中文摘要: 在运行过程中,由于受高温、高电场和机械力的作用,高压电力电缆绝缘层的高聚物材料会发生劣化,严重时会发生绝缘击穿,导致电缆运行事故的发生.分析和比较了目前几种常用的电缆局部放电检测方法,如脉冲电流法、特高频法、超声波法、电感耦合法和电容耦合法.
Abstract:Under the operation of high voltage power cables, the high polymer material of insulating layer will deteriorate.When the deterioration becomes serious, the insulating layer will break down and lead to accidents.The current partial discharge detection methods of power cables are analyzed such as pulse current method, UHF method, ultrasonic wave method, inductive coupled method and capacitance coupled method.
keywords: power cable partial discharge detection method
