SF6及常见断路器故障原因及处理办法

The Causes of Machineryfault and Treatment Method of SF6 and Common Circuit Breaker

高压断路器(开关)是电力系统中最重要的电器,是能在正常负载、过载、空载或短路故障情况下都能开合电路的一种高压电器设备。由于其直接影响电力系统的安全与稳定运行,故其现实状态下运行状态的好坏意义重大。基于断路器重要作用,即为保障电力系统安全稳定运行,该文介绍了高压断路器的常见故障并对各种故障的原因进行了详细分析,为电力系统的运行和检修人员提供一定的参考。

High voltage circuit breaker （switch） is the most important electrical equipment in power system.It can open and close the circuit of a high voltage electrical equipment under the normal load,overload,open circuit or short-circuit fault condition.The reality state is significance because it impacts the safety and sta-bility of power system directly.This paper introduces the common faults of high voltage circuit breaker and reasons for al kinds of faults are analyzed in detail for ensuring the safe and stable operation of power sys-tem.It provides certain reference for power system operation and maintenance staff.
