摘　　要：介绍一种分布式高压断路器状态在线监测装置的构成及工作原理。该装置不但具有其他同类产品所具有的功能 ,而且还增加了分闸合闸过渡过程的电压电流波形的测量记录 ,并从中分析出对高压断路器主触头损坏影响最大的电弧电流与时间的积分值、累加值、电弧重燃次数、电弧电流的最大值等参数。装置还兼有测量高压断路器绝缘拉杆泄漏电流值的功能。为高压断路器是否需要检修提供判断依据。Presents the construction and operating principle of an on line monitoring system for distributed high voltage circuit breakers, which has the function of measuring the waveforms of voltage and current in the process of disengagement and engagement in addition to the functions of similar products, and such parameters as integral and accumulated values of arc current and time, number of arc reburns and maximum value of arc current having maximum effect on damage of primary contacts of high voltage circuit breakers obtained through analysis of these waveforms, and the function of detecting leakage current from the insulated pull rod of high voltage circuit breaker as well, thereby providing the basis for judging if a high voltage circuit breaker needs check and repair.
