摘要

针对某一带气动操动机构GIS断路器分、合闸操作异常振动问题展开研究。首先在运行现场测量了断路器动作过程中的振动加速度

发现气动机构在分闸操作时的振动是导致异常振动发生的重要原因

同时研究发现降低气动机构工作气压仍不足以避免异常振动问题;然后分别对带气动和液压操动机构的试验断路器的振动强度进行了仿真计算和现场测试

发现带竖直方向布置液压机构的断路器的振动强度最小且持续时间最短。表明采用竖直方向布置液压操动机构后

GIS断路器的振动特性明显改进。

Abstract

The abnormal vibration during switching operation of a GIS circuit breaker with pneumatic mechanism was analyzed. Firstly

the vibration acceleration of the circuit breaker during switching process was measured in field

and it was found that the vibration of the pneumatic mechanism in separating operation caused the abnormal vibration

while reducing the pneumatic mechanism’s working pressure could not sufficiently avoid this abnormal vibration. Secondly

the vibration strengths of one circuit breaker with pneumatic mechanism and two circuit breakers with hydraulic mechanism were simulated and measured

and the results showed that the circuit breaker with a vertically arranged hydraulic mechanism has the minimum vibration strength and duration

which indicates that vertical arrangement of hydraulic mechanism can effectively improve vibration characteristics of GIS circuit breakers.
