摘要

气体作为绝缘与灭弧介质广泛应用于电力设备中

但由于存在温室效应和液化温度高这两个严重的环境问题

几十年来国内外众多研究机构与学者针对该问题开展了大量的研究工作

取得了很多有价值的成果。从绝缘与灭弧等方面综述了国内外对SF

替代气体的研究现状及进展情况

并着重介绍了目前该领域较为关注的几种气体

分别从单一常规气体、SF

混合气体和CF

I、c-C

、C

O等环保气体3个方面展开讨论。基于目前的研究现状

分析了SF

替代气体的研究中面临的主要问题

提出了气-固复合绝缘技术、新型环保气体分解和复合特性、散热性能、组分监测及补气策略等亟待研究的内容

旨在为我国SF

替代气体的探索与新型环保电力设备的研究提供一定的参考与借鉴。

Abstract

gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However

the application of SF

gas faces two serious problems

including the heavy global warming effect and high liquefaction temperature. To deal with this issue

lots of research institutes have carried out many experiments and theoretical investigations in recent decades

from which a lot of valuable results have been obtained. We review the recent research progress in SF

substitute gases

and emphatically introduce several gases and gas mixtures concerned recently

including single common gas

mixture

and new enviroment-friendly gas. Based on the research progress

the main problems faced are analyzed

and the is

sues needed to study urgently are proposed

such as gas-solid composite insulation technology

decomposition

and composition characteristics

heat dispersion performance

composition monitor

and gas filling strategy. Some valuable references are expected to provide for exploration on SF

substitute gases and development of new enviroment-friendly electric power devices.
