| 1 | Influence of morphological variations on the AC breakdown of XLPE insulation in submarine cable factory joints显示文摘Extruded crosslinked polyethylene(XLPE)submarine cables with factory joints play a significant role in cross-sea transmission interconnection projects.Morphological variations in the insulation of submarine cables and factory joints are caused by differences in process parameters.The dielectric properties of XLPE are affected by its morphology.In this study,samples of XLPE insulating materials were taken from the cable bulk,cable–joint transition,and factory joint,respectively,of a 500 kV high-voltage AC submarine cable.The crosslinked morphology was obtained by extraction and infrared spectrometer.The crystal morphology was obtained by the way of etchant,differential scanning calorimetry,and X-ray diffractometry.The Weibull distribution was used to gather statistics of AC breakdown strength.The results show that in comparison with the cable bulk,the contents of crosslinked byproducts are higher in the cable–joint transition and factory joint.At the same time,there is a sparse distribution in terms of crystal morphology,with the appearance of smaller grains and lower crystallinity,in the cable–joint transition and factory joint.These morphological variations would generate more heat during electron transport and lengthen the free paths of electrons,then lead to the occurrence of AC breakdown.The results might provide insights into the optimisation of the morphology of XLPE,in particular submarine cable factory joints. | Zhenpeng Zhang Jiankang Zhao Wei Zhao Lisheng Zhong Liexiang HU Wenbin Rao Mei Zheng Shaoxin Meng | 2020 | High Voltage2020，5，1： | 1 |
| 2 | A fully self-powered, natural-light-enabled fiber-optic vibration sensing solution显示文摘Fiber-optic sensors have been developed to monitor the structural vibration with advantages of high sensitivity,immunity to electromagnetic interference(EMI),flexibility,and capability to achieve multiplexed or distributed sensing.However,the current fiber-optic sensors require precisely polarized coherent lasers as the lighting sources,which are expensive in cost and suffer from the power supply issues while operating at outdoor environments.This work aims at solving these issues,through developing a fully self-powered,natural-light-enabled approach.To achieve that,a spring oscillator-based triboelectric nanogenerator(TENG),a polymer network liquid crystal(PNLC),and an optical fiber were integrated.The external vibration drove the PNLC to switch its transparency,allowing the varia-tion of the incident natural light in the optical fiber.Compared with the majority of conventional TENG-based active vibration sensors,the developed paradigm does not suffer from the EMI,without requirements of the signal preamplifica-tion which consumes additional energy.The vibration displacement monitoring was performed to validate the sensing effectiveness of the developed paradigm. | Jiaqi Wang Ho-Yin Man Cuiling Meng Pengcheng Liu Shaoxin Li Hoi-Sing Kwok Yunlong Zi | 2021 | SusMat2021，1，4： | 0 |
