| 1 | 用于现场老化交联聚乙烯电力电缆的降解评估参数(英文)显示文摘The cables are more likely to deteriorate after several years of service in Shanghai,a city with a humid climate and abundant rainfall.Before assessing the aging status of those cables,it is critical to present effective test parameters which are sensitive to the aging process under special field conditions.Therefore,we have performed water tree investigation,tensile test,and differential scanning calorimetry(DSC)test on hundreds of cable samples removed from service.A large number of typical bowtie water trees were found in cable insulation and the water tree content was proposed to characterize the degree of water treeing.Based on Arrhenius Equation and equivalent thermal history parameters estimated from DSC profiles,we also proposed a new parameter ln(t/τθ)to characterize the aging status of cable insulation,Where,t is treated duration andτθis the thermal life under treated temperature.The applicabilities of water tree content,tensile strength,and ln(t/τθ)are tested using the analysis of variance(ANOVA).Then we investigated the relationship between the tensile strength and the water tree content using regression analysis,and analyzed the relationship between ln(t/τθ)and the tensile strength.The results indicated that each of these parameters performs differently with cables which experienced different degrees of age related degradation,and can be used to identify the aging status of field aged cables.The tensile strength can reflect the water treeing condition of field aged cables very well as a commonly used functional parameter.Since ln(t/τθ)is strongly related to the tensile strength,it is an effective parameter to characterize the aging status of field aged cable insulation.Using this newly proposed parameter is more time saving because of the convenience in sampling. | LIU Fei JIANG Pingkai LEI Qingquan ZHANG Li | 2015 | 高电压技术2015，41，4： | 7 |
| 2 | 基于Arrehenius模型的电气电缆使用寿命评估技术显示文摘电气电缆是高速动车组中最重要的材料之一,准确用寿命直接影响到动车组的运行安全和车辆的运营成本。采用基于Arrehenius模型的方法对动车组电缆使用寿命进行了评估。推导Arrehenius数学模型,同时为了解决问题方便进行了相应的简化,通过最小二乘法进行了模型中参数的求取,最后通过电缆加速热老化试验验证了方法的可行性。 | 袁东辉 张海峰 刘长英 | 2017 | 佳木斯大学学报(自然科学版)2017，35，1： | 5 |
| 3 | 船用聚氯乙烯电缆剩余寿命快速评估方法显示文摘为对船用聚氯乙烯电缆的剩余寿命进行无损快速评估,本文提出一种通过剩余硬度保留率来对其进行检测的方法。在不同温度下对船用聚氯乙烯电缆进行快速热老化试验,并对其绝缘电阻、拉伸强度、硬度和断裂伸长率进行检测。在此基础上,拟合得到不同工作温度下老化时间和剩余硬度保留率之间的函数关系,建立了基于硬度的船用聚氯乙烯电缆剩余使用寿命的预测模型。根据研究结果表明:剩余硬度保留率能够用来评估船用聚氯乙烯电缆的实际老化情况,结合建立的预测模型就能完成对船用聚氯乙烯电缆使用状况的无损评估,与传统的评估方法相比,这种方法操作起来更加简单。 | 谢占宇 纪玉龙 刘宏甲 周创成 孙玉清 | 2019 | 哈尔滨工程大学学报2019，40，7： | 3 |
| 4 | 动车组高压跨接电缆加速寿命试验研究显示文摘高压跨接电缆作为动车组动力系统的重要部件,直接决定了动车组能否平稳运行。本文对动车组高压跨接电缆进行了温度-振动双维度的加速寿命试验,建立了温度应力和振动应力的函数与某寿命特征的对数函数的加速寿命模型,通过极大似然函数方法求解模型中的未知参数,获得电缆在常温、正常振动频率时的使用寿命。 | 刘博 李振辉 | 2020 | 内燃机与配件2020，，6： | 2 |
