摘要

由于其优异的灭弧及绝缘性能已被广泛应用于电力开关设备中

然而因其巨大的温室效应指数正日益受到关注并基于环保的压力成为被替代的研发热点。文中介绍了无SF

气体绝缘开关设备中干燥空气作为介质的使用及相关的问题

涉及到干燥空气的绝缘性能、干燥空气与其他绝缘介质的性能对比、干燥空气使用时对水份含量的要求

干燥空气泄漏时的检验方法以及隔离开关开断母线转移电流时所使用的原理等

以此作为无SF

以干燥空气绝缘的开关设备的应用技术基础。

Abstract

Because of its excellent insulation and arc quenching performances

is widely used in the power system such as in switchgear equipment. Because of its high global warming potential

reducing its usage or replacing SF

has become a focus from many researchers and a heat topic in the field of switchgear. The application of dry air as the insulation gas in SF

-free gas insulated switchgear and some related issues are discussed in this paper

including the insulation property of dry air

comparison of dry air with other insulation gases

the required humidity in the utilization of dry air

the detection of gas leakage

and the basic principles used in disconnector to interrupt bus bar transferring current. The paper p

rovides technical basis for dry air insulated switchgears.
