摘要
随着国民经济与社会现代化的发展与建设,我国电力行业和高速铁路的发展越来越快。作为连接各种电气设备、传输和分配电能的交联聚乙烯(XLPE)电缆终端和乙丙橡胶(EPR)电缆终端也越来越多地应用于输配电网络以及高速铁路牵引供电系统中。与此同时,电网安全运行的要求也日益严格,而电缆终端作为电缆绝缘中相对薄弱的环节,其故障率始终居高不下,引起了业界和学者的广泛关注。综述了目前研究人员发现的电缆终端缺陷的主要类型,介绍了常用于检测电缆终端缺陷的方法,并总结了这些检测方法的特点。
As the cross-linked polyethylene(XLPE) and ethylene propylene rubber(EPR) cable terminals are increasingly utilized in transmission and distribution networks, as well as the traction power supply systems of the high-speed railways, their defects and failures have attracted considerable attentions for both the industry and the scholars. Simultaneously, the standards for the safe operation of the electricity system are becoming increasingly stringent. As a relatively weak link in the cable insulation, the cable terminal have a high failure rate during its operation. Therefore, this study summarizes the most prevalent forms of cable terminal faults discovered by field operators and researchers, as well as the methods commonly employed to detect cable terminal failures. This paper can provide an overall horizon to the freshman of this field and give a comprehensive summary of the current trend in defect inspection methods of cable terminals.
