摘　　要：SF6断路器是一种将SF6气体作为灭弧介质的断路器,主要是通过SF6的气体作为绝缘介质以及灭弧介质的无油化断路器设备,其绝缘性能和灭弧特征都明显的高于油断路器。但是在实际应用的过程中会因为气压值的变化而出现压力降低等相关的一些安全问题。文章主要讲解了其在运行中存在的问题并同时提出了可行性的解决方案。SF6 circuit breaker is a kind of circuit breaker which takes SF6 gas as arc extinguishing medium.It is mainly an oil-free circuit breaker with SF6 gas as insulating medium and arc extinguishing medium.Its insulation performance and arc extinguishing characteristics are obviously higher than that of oil circuit breaker.But in the process of practical application,there will be some safety problems such as pressure drop due to the change of air pressure value.This paper mainly explains the problems in operation and puts forward feasible solutions.
