断路器综合在线监测分析

介绍了一种较适用的断路器开断电寿命计算方法,指出高压断路器绝缘监测方面应注意的问题;讨论了一种基于分合闸线圈电流电压的全工况断路器二次回路完好性监测方法;同时对目前所采用的各种监测方法存在的问题做了总结,对如何更准确有效地计算高压断路器燃弧时间以及如何简单有效地实现对高压断路器机械特性进行监测的方法做了展望。

Comprehensive On-line Monitoring and Measurement Analysis of Circuit Breakers

In the papers we have summarized the ways about the online monitoring of the high voltage circuit breakers in transformer substation at present.A way based on several parameters to monitor the mechanical status of breaker is discussed.After having compared all kinds of ways to calculate the electric life of the circuit breaker,we introduce an applied method.Various attentive problems about monitoring the insulation of the circuit breaker are pointed out.A way to monitor the integrity of manipulative circuit of breaker based on the current and voltage is discussed.At the same time we have pointed out another problems about online status monitoring of breaker.We also have prognosticated the ways to accurately calculate the arc burning time and monitor the mechanical status in the papers.
