变电站内SF_6断路器性能特点及其运行维护

SF_6 Circuit Breaker Performance Characteristic and Its Running Attention of the Substation Inside

变电站高压断路器维护工作对电力系统稳定运行、灵活调度及故障处理起关键作用,是各地各级调度控制中心实现集中调控、继电保护装置控制的最主要、最直接对象,也是变电运维人员停、送电工作中配合调度操作的开断、关合电网电路的主要设备。目前,国内变电站所应用电压等级在35kV及以上的断路器中,以SF_6断路器为主。本文主要对SF_6断路器结构特征、性能特点、日常维护工作、常见故障类型及处理办法进行了介绍。

The maintenance work of high voltage circuit breaker for substations play a key part in stable eperation,flexibe dispatching and fault processing of the power system. It is the most main and direct object for each place and each stage dispetding control center to realize central regulation and control and relay protection control. It is also the main equip meat of closing network circuits. The paper presents the structural characteristiss,performance characteristic,routineattention and common faults of SF6 circuit breaker.
