摘要
空气绝缘起始放电电压在不同压力下表现出不同的特征。介绍了在不同电极系统和不同压力下的空气绝缘局部放电模拟实验方法,对气体放电机理、电子崩产生过程以及空气压力对放电起始电压的影响进行分析探讨。通过模拟实验得出,在给定电极间隙下气体的起始放电电压随气体压力的增大而增大。
The initial discharge voltage using pressured air as insulation medium has different characters under diverse pressures. The simulative experiment approaches to air insulation partial discharge in diiFerent elec-trodes system and various pressures are introduced, and the mechanism of air discharge, the course of ava-lanche and the effect of air pressure on initial discharge voltage are analyzed and discussed in this paper. The results of simulation experiment showed that with increase in air pressure, there occurs increase in original discharge voltage of air.
