SF_6混合气体在开关设备中的应用

摘要

Introduced the SF6 gas has the fine extinguishing of arc and the insulating ability,but the SF6 gas is one kind of recognition greenhouse gas,under the premise of reduce emissions of greenhouse gas in the whole world,in order to reduce the use of SF6 gas,the switching equipment industry has begun to make use of SF6 gas mixtures to do for equipment＇s insulation and the extinguishing of arc medium.This article also introduced the ratio selection of SF6 gas mixtures,the insulating ability,the extinguishing of arc mechanism,the gas recovery method and so on.%介绍了SF6气体具有优良的灭弧和绝缘性能,但SF6气体是一种公认的温室气体,在全球减排温室气体的前提下,为减少SF6气体的使用,开关设备行业开始采用SF6混合气体做为设备的绝缘和灭弧介质。本文同时介绍了SF6混合气体的比例选择、绝缘性能、灭弧机理、气体回收方法等。
