Phenomenon Analysis for Frequent Pressuring of 800 kV Tank SF6 Circuit Breaker’s Operating Mechanism
摘要
高压断路器是变电站中仅次于变压器的高压开关设备
起着控制和保护的作用
为了保证750 kV超高压输变电工程安全运行
排除高压电气设备运行中可能存在的安全隐患
对黄河750 kV变电站采用的LW13-800罐式SF6断路器操动机构进行了介绍
分析了变电站断路器操动机构出现的频繁打压现象
并结合750 kV变电站现场运行经验提出了相应的解决办法和预防措施
对今后加强LW13-800罐式SF6断路器现场运行具有一定的借鉴意义。
Abstract
The importance of high-voltage circuit breaker is only inferior to transformer in substation
its function is the controlling and protection of the system.This paper introduced operating mechanism of LW13-800 tank circuit breaker’s in Huanghe 750 kV substation
analysed the phenomenon of frequent pressuring of circuit breaker’s operating mechanism
and presented the solutions and preventive measures to such problems which can be of significance to strengthen LW13-800 tank circuit breaker’s field operation in the future.
