摘要
SF6气体在电力工业中用于断路器、开关设备及其他电气设备的绝缘和灭弧,在中高压设备中有广泛的应用,世界每年生产的SF6气体80%用于电力设备中。然而,SF6是一种很强的温室气体,其对全球气候变暖的影响程度是二氧化碳的23900倍,因而寻找与之性能相当的替代气体是近几年国内外研究工作的重点。本文从绝缘角度介绍了国内外SF6替代气体的研究现状以及最新发展,对研究工作提供有益的参考。
SF6 gas is used in the power industry for the insulation and arc extinguishing of circuit breakers, switchgear and other electrical equipment. It is widely used in medium and high voltage equipment. The SF6 gas produced annually in the world is used in power equipment at 80%. However, SF6 is a very strong greenhouse gas that has 23, 900 times as much carbon dioxide as global warming. Therefore, looking for a substitute gas with comparable performance has been the focus of recent years at home and abroad. Originally introduced from the perspective of insulation at home and abroad SF6 alternative gas research status and the latest development of the research provide a useful reference.
