在开发新型的300kV及500kV的气体断路器中电流开断后热SF6介质恢复特性的研究
Gaoya dianqi, 1987 一、引言 许多学者已进行了热SF6气体的介电特性的试验研究,但他们只是研究了稳定条件下或电极间隙中气体均匀分布时的SF6介电强度。实际上断路器在开断和介电恢复过程中,断路器中或靠近电屏蔽处,SF6气体的压力和温度并不是均匀的,存在温度和压力梯度以及气体流动时间隙的介电特性问题,这些都是很有现实意义的。本文所研究的就是关于流动的热SF6气体的击穿特性。气体流动或是由电弧能量本身造成,或是由断路器压气活塞的运动而形成。研究的方法是;根据设计的试验装置,在灭弧室由电弧加热SF6气体,并把这种热气体引至电极间隙,
