电力电缆运行状态的监测研究

结合北京电网电力电缆线路现有的主要方式、发展方向以及在线检测技术的应用研究,为实现电力电缆线路运行状态监测,保证运行安全,对4种监测技术和方法进行了研究,通过分析比较技术特点、实用方法、应用范围和优缺点等,得到不同电力电缆线路和具体位置适宜的状态监测方法,还给出了部分参考标准。现阶段,在进行电力电缆运行状态监测的同时,赞同北京电网正在执行的电力电缆线路预防性试验规程。但状态监测应用成熟后,要逐渐取代电缆线路预防性试验。

Study on Monitoring of Operation Condition for Power Cable

Combined with the existing major way and development direction as well as online detection technology for power cable line in Beijing power network, the 4 kinds of monitoring technology and method were studied for realizing the monitoring of operation condition of power cable line and guaranteeing operation safety. Through the analysis and comparison of technical characteristics, practical method, application scope and advantages and shortcomings, the suitable condition monitoring method of different power cable line and specific location, and the part of reference standard were given. After ripening of condition monitoring application, the preventive test of power cable line will be replaced by condition monitoring gradually.
