摘要
本文提出一种注入式高压隔离开关刀闸状态在线监测系统,通过电压互感器开口三角绕组,将外加电源信号注入高压隔离开关刀闸监视回路,在线监视高压隔离开关刀闸的状态。本方法能够可靠监测轻载、空载、重载线路高压隔离开关刀闸的运行状态。同时还具有监测精度高、速度快、持续工作能力强等优点,可以方便、快捷、可靠地监测开关刀闸运行状态,很好地满足系统对开关刀闸运行状态监视的需求。
This paper proposed an on-line monitoring system for the injection high-voltage isolating switch knife gate state.The injected signal power supply injects the power signal into the monitoring circuit of high-voltage dis?connector switch through the open triangle winding of voltage transformer,and monitors the state of the high-voltage disconnector switch on-line.This method can reliably detect the operating state of the switch and switch of the high voltage isolation switch for light load or no load lines.At the same time,it has the advantages of high detection accura?cy,high speed and strong continuous working ability.It can detect the operation status of switch conveniently,quick?ly and reliably,which satisfies the requirement of the system for monitoring the operation status of switch switch.
