摘要

《京都议定书》将SF

气体列为限制排放的6种温室效应之一。为减少SF

气体的使用量

采用SF

和SF

/CF

混合绝缘气体作为SF

替代气体是现实可行的

国内外已在部分设备中投入使用。目前

国内外关于SF

混合绝缘气体电气设备泄漏检测技术的研究较少

现有SF

检测技术能否直接应用于混合绝缘气体的检测是目前亟须解决的问题。文中以SF

和SF

/CF

两种混合绝缘气体为试验对象

模拟不同混合比的混合绝缘气体在不同距离和风力等条件下的泄漏情况

利用红外成像仪等仪器进行检测

得出了仪器的检出限值

并提出检测的的最佳条件

证明SF

泄漏检测技术可以应用于混合绝缘气体的现场检测

对于SF

混合绝缘气体泄漏现场检测具有一定的指导意义。

Abstract

gas is regarded as one of the six greenhouse gases in Kyoto Protocol. In order to reduce the amount of SF

usage

it has been shown to be feasible to use SF

and SF

/CF

mixtures as SF

alternatives and the mixtures have been used in some of the electrical equipment both domestically and abroad. There has been very little research on the detection technology of SF

mixtures

and weather the det

ection technology of SF

gas is applicable to SF

mixtures is an issue that needs to be addressed. In this paper

we make SF

and SF

/CF

mixtures as experimental subjects

simulate the leakage situations of SF

mixtures with different mixing ratios at different distance and under different wind speed. Infrared camera is used to detect gas leakage and to obtain the detection limit of the instrument

thus defining the optimum detecting conditions. It has been shown that the leakage detection technology for SF

gas can be used to detect SF

mixture leakage

which provides sensible guidance for the on-site detection of SF

mixture leakage.
