Abstract

Since SF/sub 6/ gas has been specified as one of the greenhouse gases, we attempt to develop new insulation gases or gas mixtures alternative to SF/sub 6/ gas for gas insulated switchgears (GIS). In this paper, we investigated partial discharge (PD) and breakdown (BD) characteristics of CO/sub 2/ gas and CO/sub 2/ gas mixtures as one of the promising candidates without using SF/sub 6/ gas. Experimental results revealed PD inception and BD strengths for different gas pressure and CO/sub 2/ content under lightning impulse voltage and ac high voltage application.

非均匀电场作用下CO/sub - 2/和CO/sub - 2/气体混合物的电绝缘特性
由于SF/sub - 6/气体已被指定为温室气体之一，我们试图开发新的绝缘气体或气体混合物替代SF/sub - 6/气体用于气体绝缘开关设备(GIS)。本文研究了CO/sub - 2/气体和CO/sub - 2/气体混合物在不使用SF/sub - 6/气体的情况下的局部放电(PD)和击穿(BD)特性。实验结果表明，在雷击电压和交流高压作用下，不同气体压力和CO/sub 2/含量下的PD起始和BD强度。
