摘要
实验表明,在SF_6中加入10％的空气可明显提高在极不均匀电场中的雷电冲击击穿电压。因此在气体绝缘开关柜中采用混合比为90/10的SF_6/空气混合气体,可望使开关柜尺寸进一步缩小。
Experiments snow that adding 10% air to SF6 gas can apparently increase the lightning impulse breakdown voltage of SF6 in a highly non-uniform electric field.It is expected that the dimension of cubicle type GIS can be further reduced if the SF6/air (90/10)gas mixture is used.
