Distributed partial discharge on-line monitoring system

The invention discloses a distributed partial discharge on-line monitoring system, which is characterized in that a signal monitoring system is arranged in a distributed manner to monitor partial discharge signals of power equipment of each monitoring place, and the partial discharge signals are transmitted to a central processing system for unified processing and analysis through optical fibers in a time division multiplexing manner; the problems of instability of long-distance signal transmission and signal attenuation in a traditional detection method are avoided, and the cost of large-range online monitoring is reduced. 本申请公开了一种分布式局部放电在线监测系统，分布式设置信号监测系统对各个监测地的电力设备的局部放电信号进行监控，时分复用地通过光纤将局部放电信号传输给中央处理系统进行统一处理和分析，避免了传统检测方法中长距离信号传输的不稳定和信号衰减的问题，降低大范围在线监测的成本。
