| 1 | 纳米氮化铝改性对芳纶1313绝缘纸介电特性的影响显示文摘聚合物纳米复合材料因其优良的介电性能在电介质绝缘领域得到了广泛的应用。为获得性能优良的绝缘纸,将纳米氮化铝(AlN)添加到芳纶1313中。将改性后的绝缘纸进行浸油处理,研究了AlN对油浸芳纶1313介电性能的影响。结果表明:纳米Al N能有效降低绝缘纸的电导电流,以及提升其交流击穿电场强度;同时Al N能够抑制空间电荷向介质内的注入、迁移和积聚,使绝缘纸内空间电荷分布更加均匀。另外聚合物纳米材料的界面特性使得改性后绝缘纸的相对介电常数和介电损耗值有所升高,介损松弛峰值也向低频段移动。芳纶1313/Al N油浸绝缘纸介电性能的变化归因于纳米粒子与聚合物之间的界面效应使界面区域陷阱浓度和深度增大,限制了电荷的运动。 | 柏舸 廖瑞金 刘娜 柳海滨 杨丽君 Shakeel Akram | 2015 | 高电压技术2015，41，2： | 15 |
| 2 | Hydrogen evolution and electromigration in the corrosion of aluminium metal sheath inside high‐voltage cables显示文摘The urgent need for power transmission is the reason for leading research on the safer operation of high‐voltage cables.These high‐voltage cables are emerging as an efficient technology for underground power transmission.However,the electrochemical corrosion of aluminium(Al)metal sheaths in these cables is a common and challenging degradation process.Herein,the corrosion mechanisms and electrochemical analysis are investigated by using scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FTIR),electrochemical impedance spectroscopy(EIS)and laboratory‐designed electro-chemical characterisation techniques.In the corrosion experiments,the authors evaluated the corrosion rate by measuring the release rate of hydrogen gas and explored the different roles of sodium polyacrylate(NaPA)during the corrosion process.It is found that the complexation reactions between NaPA and Al inhibited corrosion while increased the resistance of the buffer layer.The proposed mechanisms of corrosion in this study can improve the lifespan and sustainability of high‐voltage power transmission. | Yidong Chen Kai Zhou Jiamin Kong Shakeel Akram Xiancheng Ren Xiaoshan Zhang Yuan Li Qi Zhao | 2022 | High Voltage2022，7，2： | 7 |

| 4 | Insulating materials for realising carbon neutrality:Opportunities,remaining issues and challenges显示文摘The 2050 carbon-neutral vision spawns a novel energy structure revolution,and the construction of the future energy structure is based on equipment innovation.Insulating material,as the core of electrical power equipment and electrified transportation asset,faces unprecedented challenges and opportunities.The goal of carbon neutral and the urgent need for innovation in electric power equipment and electrification assets are first discussed.The engineering challenges constrained by the insulation system in future electric power equipment/devices and electrified transportation assets are investigated.Insulating materials,including intelligent insulating material,high thermal conductivity insulating material,high energy storage density insulating material,extreme environment resistant insulating material,and environmental-friendly insulating material,are cat-egorised with their scientific issues,opportunities and challenges under the goal of carbon neutrality being discussed.In the context of carbon neutrality,not only improves the understanding of the insulation problems from a macro level,that is,electrical power equipment and electrified transportation asset,but also offers opportunities,remaining issues and challenges from the insulating material level.It is hoped that this paper en-visions the challenges regarding design and reliability of insulations in electrical equipment and electric vehicles in the context of policies towards carbon neutrality rules.The authors also hope that this paper can be helpful in future development and research of novel insulating materials,which promote the realisation of the carbon-neutral vision. | Chuanyang Li Yang Yang Guoqiang Xu Yao Zhou Mengshuo Jia Shaolong Zhong Yu Gao Chanyeop Park Qiang Liu Yalin Wang Shakeel Akram Xiaoliang Zeng Yi Li Fangwei Liang Bin Cui Junpeng Fang Lingling Tang Yulin Zeng Xingtao Hu Jiachen Gao Giovanni Mazzanti Jinliang He Jianxiao Wang Davide Fabiani Gilbert Teyssedre Yang Cao Feipeng Wang Yunlong Zi | 2022 | High Voltage2022，7，4： | 4 |
| 5 | 重复方波参数对变频电机绝缘放电频域能量分布影响研究显示文摘采用双极性重复方波电压,借助特高频测试方法,实验研究了重复方波电压幅值、频率、占空比、上升时间对变频电机匝间绝缘放电频域能量分布的影响规律。结果表明:放电0.50 GHz以上频域能量随占空比的增大而明显增加;频域各频段能量随脉冲电压幅值的增大而增加,1.50 GHz以上高频能量随频率的提升不断衰减;脉冲电压上升速率对放电频域能量影响显著,放电脉冲在1.00~2.00 GHz高频能量随电压上升速率的增大而增加。在设计用于高频、陡脉冲电压下变频电机绝缘PDIV测试的特高频传感器时,应充分考虑上述脉冲参数对频域能量的分布影响,以提升PDIV测试的灵敏度和信噪比。 | 于超凡 王鹏 马世金 李佩宜 Shakeel AKRAM | 2022 | 绝缘材料2022，55，2： | 3 |
| 6 | Pulse width modulation voltage source deadtime effect on partial discharge and lifetime of inverter‐fed motor insulation显示文摘This paper analyses the impact of square wave pulse voltage deadtime on the partial discharge(PD)and the lifetime of turn-to-turn insulation.A bipolar repetitive pulse voltage with a deadtime of 0–10μs is produced using double half-bridge solid-state switches having push–pull technology controlled by a field-programmable gate array.The mechanism of the discharge process at rising and falling edges of the pulse voltage before and after deadtime is analysed in detail.The discharge amplitude and PD probability at the rising/falling edges of the voltage waveform increase as the deadtime increases from 0 to 10μs due to the remanent charges.The number of PD and their intensity is higher at the first rising/falling edges of pulse voltage as compared to the second rising/falling edges for all deadtimes 0–10μs.As the deadtime increases beyond 2μs,the number of PDs increases and concentrates at a specific phase angle of rising/falling edges.These localise discharges degrade the insulation material and reduce its lifetime.This study helps to identify the inverter-fed motor insulation faults due to deadtime.It can provide guidelines to motor insulation designers to determine the limit value of deadtime to compensate PD and ensure the safer operation of such motors. | Shakeel Akram Peng Wang Pengfei Meng Gian Carlo Montanari Farhan Hameed Malik | 2022 | High Voltage2022，7，6： | 2 |
| 7 | 高压电缆阻水缓冲层的白斑现象及析氢腐蚀机理显示文摘近年来,高压电缆中的电化学腐蚀诱发了多起本体击穿故障,造成了重大的经济损失。这种故障的特点是击穿的电缆中的缓冲层上有明显的白斑,然而,产生这种故障的机理尚未明确。针对这一问题,该文研究不同样本中白斑的成分,并用电化学手段定量分析白斑产生的过程,并研究白斑产生的电化学机理。首先,通过红外光谱(Fourier transform infrared spectroscopy,FTIR)、X射线能谱(energy dispersive spectrometer, EDS)和扫描电子显微镜(scanning electron microscope,SEM)分析事故现场白斑的化学成分和形貌。随后,在实验室培养了白斑,分析其化学成分,并把结果与事故现场的分析结果进行对比。通过对比FTIR和EDS结果可以发现,故障电缆和实验室培养的白斑的主要成分都是氢氧化铝,根据相应的电化学反应方程,可认为这是一种在交流电场下的析氢腐蚀现象。通过对腐蚀副产物氢气的浓度检测,水分、电流密度和是否含有阻水粉等会影响腐蚀速率。根据电化学分析,聚丙烯酸钠在腐蚀初期吸收水分,加速了腐蚀;而在腐蚀过程中,其与铝离子络合形成不吸水的络合物,反而抑制了腐蚀,但增加了缓冲层的电阻率,这可能会导致局部过热。最后提出了白斑产生的电化学机理,该研究可为高压电缆的腐蚀检测和新的缓冲层设计提供理论依据。 | 陈熠东 周凯 雷清泉 任显诚 孔佳民 李原 赵琦 李泽瑞 Shakeel Akram | 2023 | 中国电机工程学报2023，43，12： | 2 |
| 8 | 正弦及双极性脉冲电压下变频电机匝间绝缘PDIV对比分析显示文摘在频率为50 Hz的正弦、双极性方波和双极性短脉冲电压下,采用新能源汽车3种典型的具有耐电晕特性的匝间绝缘绞线对,研究了3种电压对其局部放电起始电压(PDIV)特性的影响规律。结果表明:频域滤波后的有效带宽内,双极性重复短脉冲及方波电压下的放电频域能量主要分布在0.5~0.9 GHz;保持其他测试环境不变,正弦及双极性重复方波电压下的PDIV几乎相等,而正弦和方波电压下的PDIV比双极性重复短脉冲下的PDIV低约20%,并且随着脉宽的增加,双极性重复短脉冲电压下的PDIV呈下降趋势。根据研究结果,在对匝间绝缘进行PDIV测试时,正弦和方波电压是较为保守评估变频电机匝间绝缘PDIV的测试电压;在对绞线对等容性试样进行PDIV测试时,可考虑采用正弦电压替代脉冲电压。 | 师洋 王鹏 刘新霆 程驰宙 郭厚霖 Shakeel AKRAM | 2022 | 绝缘材料2022，55，1： | 1 |
| 9 | 基于三线法的低压散绕变频电机绝缘短板判定方法研究显示文摘低压散绕变频电机匝间绝缘的局部放电起始电压(PDIV)随脉冲电压上升时间变化而变化,导致现行标准难以发现上升时间变化时的绝缘系统短板。对此,考虑脉宽调制上升时间,联合重复脉冲和正弦电压下的PDIV测试技术,提出了确定低压散绕变频电机绝缘短板的三线法。首先,在正弦电压下测定主绝缘和相间绝缘PDIV,得到主绝缘和相间绝缘的PDIV最小值分布;然后,使用上升时间为50~200 ns的重复脉冲对低压散绕变频电机匝间绝缘进行PDIV测试,得到PDIV随上升时间变化的拟合曲线;最后,根据确定的三线图,考虑电机运行时上升时间,确定绝缘系统短板,并通过击穿实验验证三线法的可行性。结果表明:采用此方法可以对低压散绕变频电机绝缘短板进行判定,通过击穿实验验证了三线法的可行性。 | 程驰宙 王鹏 刘新霆 师洋 郭厚霖 Shakeel AKRAM | 2022 | 绝缘材料2022，55，5： | 0 |
| 10 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 11 | The effect of pulse voltage rise rate on the polypropylene surface hydrophilic modification by ns pulsed nitrogen DBD显示文摘The nanosecond(ns) pulsed nitrogen dielectric barrier discharge(DBD) is employed to enhance the hydrophilicity of polypropylene(PP) surface and improve its application effect.The discharge characteristics of the ns pulsed nitrogen DBD with different pulse rise times(from 50to 500 ns) are investigated by electrical and optical diagnostic methods and the discharge uniformity is quantitatively analyzed by image processing method.To characterize the surface hydrophilicity,the water contact angle(WCA) is measured,and the physical morphology and chemical composition of PP before and after modification are analyzed to explore the effect of plasma on PP surface.It is found that with increasing pulse rise time from 50 to 500 ns,DBD uniformity becomes worse,energy efficiency decreases from 20% to 10.8%,and electron density decrease from 6.6 × 10^(11)to 5.5 × 10^(11)cm^(-3).The tendency of electron temperature is characterized with the intensity ratio of N_(2)/N_(2)^(+)emission spectrum,which decreases from 17.4 to15.9 indicating the decreasing of T_(e) with increasing pulse rise time from 50 to 500 ns.The PP surface treated with 50 ns pulse rise time DBD has a lower WCA(~47°),while the WCA of PP treated with 100 to 500 ns pulse rise time DBD expands gradually(~50°–57°).According to the study of the fixed-point WCA values,the DBD-treated PP surface has superior uniformity under50 ns pulse rise time(3° variation) than under 300 ns pulse rise time(8° variation).After DBD treatment,the increased surface roughness from 2.0 to 9.8 nm and hydrophilic oxygencontaining groups on the surface,i.e.hydroxyl(-OH) and carbonyl(C=O) have played the significant role to improve the sample’s surface hydrophilicity.The short pulse voltage rise time enhances the reduced electric field strength(E/n) in the discharge space and improves the discharge uniformity,which makes relatively sufficient physical and chemical reactions have taken place on the PP surface,resulting in better treatment uniformity. | 刘峰 李舒豪 赵昱雷 Shakeel AKRAM 张丽 方志 | 2023 | Plasma Science and Technology2023，25，10： | 0 |
| 12 | Significantly enhanced flashover voltage of epoxy in vacuum by graded surface roughness modification显示文摘The flashover strength of epoxy(EP)insulations in the High voltage direct current applications of future energy grids can be improved by tailoring their surface condition.This work aims to improve the DC surface flashover characteristics of EP after being treated with sandpaper of different gradings.Samples with virgin EP and homogenously modified EP considering varying surface roughness(R_(a)=0.54,3.16,5.24,and 8.35μm)are prepared.Different experimental characterisations,such as water contact angle,surface intrinsic conductivity,surface voltages,flashover strength,and trap distributions are conducted and evaluated to analyse the difference between virgin and treated EP.Moreover,based on the obtained experimental results of homogenously treated EP and theoretical analysis,the concept of surface functionally graded materials(SFGMs)is put forward.The flashover voltages of homogenously treated EP are augmented significantly compared to virgin EP regardless of the voltage polarity and enhanced by enhancing the surface roughness.The sample T_(Model‐C) with SFGM design shows a 45.02%and 43.75%improvement in the negative and positive flashover voltages than that of the virgin EP.In the end,COMSOL simulations are conducted to justify the experimental findings and to analyse the difference between virgin and modified samples in terms of electric field distribution. | Inzamam Ul Haq Feipeng Wang Shakeel Akram Muneeb Ahmed Muhammad Tariq Nazir | 2023 | High Voltage2023，8，5： | 0 |
| 13 | Impact of air pressure variations on electrical vehicle motor insulation显示文摘Variation in air pressure severely affects the insulation of electric vehicle(EV)motors,hence weakening the reliability of EVs for safe operation.Nomex‐polyimide‐Nomex,a typical insulation material for EV motors,was used to investigate the motor insulation performance under different air pressures.The results show that the partial discharge inception voltage is significantly reduced for EV motors operated at lower air pressures,and the probability of partial discharge(PD)occurrence is increased.The macroscopic results reveal that the active area of the PD expands at low pressure,while the non‐corroded ring appears in the centre.Additionally,although the number and amplitude of the PD increase significantly with decrease in air pressure,the active area of the PD expands and electrical stress on the insulation per unit area increases slowly.Therefore,when the pressure decreased from 60 to 40 kPa,the endurance life does not show a significant downward trend.Furthermore,the dielectric constant and loss of the low‐pressure samples significantly change during the ageing process,which further indicates critical degradation of the insulation.The aforementioned investigations reveal that the air pressure at different altitudes has a significant impact on the performance of insulation materials. | Peng Wang Chaofan Yu Shakeel Akram Ziyuan Fan Wenhuan Zhao | 2023 | High Voltage2023，8，5： | 0 |
| 14 | Electrical Tracking,Erosion and Fire Retardancy Performance of Silicone Rubber Insulation Containing Aluminum Trihydrate,Graphene and Glass Fiber Additives显示文摘Silicone rubber composite is a priority electrical insulating material used in high-voltage outdoor insulation applications.Low electrical tracking/erosion and poor flame resistance performance of silicone rubber once ignited,substantially reduce its working life.This paper attempts to investigate tracking/erosion performance of room temperature vulcanized(RTV)silicone rubber along with flame retardant parameters using aluminum trihydrate(ATH),graphene nanosheets(GN)and milled glass fiber(GF)additives.The inclined plane test(IPT)was performed in line with criteria defined in IEC 60587 using step-up tracking voltage method while flame retardancy is evaluated according to ASTM E 1354.0 using a cone calorimeter.Results suggest 30% of ATH assists in improving physical tracking/erosion resistance of pristine silicone elastomer rubber by impeding development of leakage current and a great reduction in maximum average temperatures on the surface of RTV2.Further improvement in performance of RTV2 is achieved through introduction of 1%of GN and 5% of GF as seen in RTV4.Moreover,30% of ATH reduces heat release rate and smoke production rate,and this trend is improved with the introduction of GN/GF.RTV4 has pop up as the most promising silicone rubber composite with excellent electrical tracking,erosion,and flame resistance performance relative to its counterparts in this study. | M.Tariq Nazir Arslan Khalid B.Toan Phung Arup K.Das Peter Cheetham Ashish Paramane Shakeel Akram Khoi Loon Wong | 2023 | CSEE Journal of Power and Energy Systems2023，9，5： | 0 |
| 15 | A classification of genes involved in normal and delayed male puberty显示文摘Puberty is a pivotal biological process that completes sexual maturation to achieve full reproductive capability.It is a major transformational period of life,whose timing is strongly affected by genetic makeup of the individual,along with various internal and external factors.Although the exact mechanism for initiation of the cascade of molecular events that culminate in puberty is not yet known,the process of pubertal onset involves interaction of numerous complex signaling pathways of hypothalamopituitary-testicular(HPT)axis.We developed a classification of the mechanisms involved in male puberty that allowed placing many genes into physiological context.These include(i)hypothalamic development during embryogenesis,(ii)synaptogenesis where gonadotropin releasing hormone(GnRH)neurons form neuronal connections with suprahypothalamic neurons,(iii)maintenance of neuron homeostasis,(iv)regulation of synthesis and secretion of GnRH,(v)appropriate receptors/proteins on neurons governing GnRH production and release,(vi)signaling molecules activated by the receptors,(vii)the synthesis and release of GnRH,(viii)the production and release of gonadotropins,(ix)testicular development,(x)synthesis and release of steroid hormones from testes,and(xi)the action of steroid hormones in downstream effector tissues.Defects in components of this system during embryonic development,childhood/adolescence,or adulthood may disrupt/nullify puberty,leading to long-term male infertility and/or hypogonadism.This review provides a list of 598 genes involved in the development of HPT axis and classified according to this schema.Furthermore,this review identifies a subset of 75 genes for which genetic mutations are reported to delay or disrupt male puberty. | Maleeha Akram Syed Shakeel Raza Rizvi Mazhar Qayyum David J Handelsman | 2023 | Asian Journal of Andrology2023，25，2： | 0 |
| 16 | Physical,Thermal and Partial Discharge Evaluation of Nano Alumina Filled Silicone Rubber in an Inclined Plane Test显示文摘Silicone rubber(SiR)composite material is a modern-day insulator for high voltage outdoor applications.The imperfection attributed to SiR is its weak resistance to tracking and erosion when exposed to an outdoor polluted environment which reduces its operational lifetime.This paper investigates the performance of SiR with the addition of 0,1,2.5,5,10 and 20%by weight contents of nano alumina(Al_(2)O_(3)).Inclined plane tests are performed according to IEC 60587 using the step up tracking voltage method with an initial voltage of 3.0 kV and the contaminant solution flow rate is maintained at 0.3 ml/min using a peristaltic pump.The applied voltage level is increased at a rate of 0.25 kV/h.Results suggest that physical tracking,erosion,RMS leakage current and surface partial discharge(PD)performance of samples is improved with the addition of nano alumina.The tracking length,eroded mass,RMS leakage current and average PD magnitude are measured 22%,79%,30%and 52%lesser in 20 wt%relative to 0 wt%,respectively.A thermal distribution analysis is undertaken with infrared camera and it is discovered that heat is accumulated in the discharge area of the liquid flow.The maximum temperature on the insulating specimen is decreased with increasing nanofiller contents.The above promising findings can be due to better thermal stability with low chain mobility at the interaction zone of SiR and alumina.Moreover,less liquid evaporation due to better thermal conduction and improved physical bonding between SiR and nano alumina are possible reasons behind the excellent performance of nanocomposites. | M.Tariq Nazir Faizan Tahir Butt Haider Hussain B.Toan Phung Shakeel Akram M.Shoaib Bhutta Ghulam Yasin | 2022 | CSEE Journal of Power and Energy Systems2022，8，4： | 0 |
| 17 | Sub-percent precision measurement of neutrino oscillation parameters with JUNO显示文摘JUNO is a multi-purpose neutrino observatory under construction in the south of China.This publication presents new sensitivity estimates for the measurement of the △m_(31)^(2),△m_(21)^(2),sin^(2)θ_(12),and sin^(2)θ_(13) oscillation parameters using reactor antineutrinos,which is one of the primary physics goals of the experiment.The sensitivities are obtained using the best knowledge available to date on the location and overburden of the experimental site,the nuclear reactors in the surrounding area and beyond,the detector response uncertainties,and the reactor antineutrino spectral shape constraints expected from the TAO satellite detector.It is found that the △m_(21)^(2) and sin^(2)θ_(12) oscillation parameters will be determined to 0.5%precision or better in six years of data collection.In the same period,the △m_(31)^(2) parameter will be determined to about 0.2%precision for each

| 18 | JUNO sensitivity on proton decay p→νK^(+)searches显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)is a large liquid scintillator detector designed to explore many topics in fundamental physics.In this study,the potential of searching for proton decay in the p→νK^(+)mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification.Moreover,the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals.Based on these advantages,the detection efficiency for the proton decay via p→νK^(+)is 36.9%±4.9%with a background level of 0.2±0.05(syst)±0.2(stat)events after 10 years of data collection.The estimated sensitivity based on 200 kton-years of exposure is 9.6×1033 years,which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies. | Angel Abusleme Thomas Adam Shakeel Ahmad Rizwan Ahmed Sebastiano Aiello Muhammad Akram 安丰鹏 安琪 Giuseppe Andronico Nikolay Anfimov Vito Antonelli Tatiana Antoshkina Burin Asavapibhop

| 19 | Improving the polarisation and depolarisation current measuring method to avoid ground wire interference显示文摘The ground wire is significantly interfered by the current above 1μA in the industrial field during the traditional polarisation and depolarisation current(PDC)measurement.This paper explains a method to test PDC from high-voltage wire using a principle of equipotential picoammeter,which is completely isolated from the ground wire and connected in series with the high voltage wire.In this method,a device is designed with a multi-range automatic switching function.The device can automatically switch the test range current from 1 pA to 10 mA with a resolution of 1 pA.To demonstrate the device and effectiveness of this new method,the traditional and the proposed new device are used to test the PDC of cable samples in the laboratory as well as in an industrial environment.It is worth noting that there is almost no interference on the Earth wire in the laboratory environment but massive interference in the industrial environment using a traditional method of PDC measurement from ground or Earth wire.The new method of high-voltage testing can efficiently eliminate the interference and accurately measure PDC in a strong industrial interference environment.Furthermore,the wiring of this new method and device is relatively simple,which is convenient for industrial applications. | Fan Yang Kai Zhou Shakeel Akram Muhammad Tariq Nazir | 2022 | High Voltage2022，7，5： | 0 |
| 20 | 重复方波电压上升时间对交联聚乙烯电树特性影响研究显示文摘相对于传统燃油推进,全电推进具有低能耗、低噪音、稳定可靠等优势,已成为各国海军未来发展方向。变频驱动系统为全电推进提供核心动力,其安全至关重要。连接电缆位于逆变器和电机之间,是变频驱动系统的重要组成部分,长期承受高频过电压冲击,其绝缘有早期失效的潜在隐患。在电应力下电树产生是电缆绝缘失效的重要原因,研究电力电子应力下电缆绝缘的电树特性具有重要意义。本文在上升时间320~960 ns、峰峰值12 kV、频率5 kHz的重复方波电压下,研究了上升时间对交联聚乙烯电树特性的影响规律。研究表明:重复方波上升时间对交联聚乙烯电树引发特性影响显著,随着上升时间减小,相同时间内电树引发概率和引发长度明显增加,电树形态由丛状和单一的枝状逐渐转变为密集树枝状。其主要原因可能为:在重复方波电压的上升沿和下降沿,方波电压极性反转和介质中空间电荷迁移、恢复具有时间差,会引起背景电场与空间电荷的附加电场正向叠加。研究结果有望为逆变器供电条件下电缆绝缘设计提供实验和理论依据。 | 黄路 王鹏 朱英伟 陈逸雯 Shakeel Akram 马世金 | 2023 | 电工电能新技术2023，42，5： | 0 |
