高气压下氮氧混合气体的工频击穿特性

Gaoya dianqi
文中通过工频击穿实验研究了不同电场均匀度、配比、气压下氮氧混合气体的工频绝缘特性。实验发现：板—板电极下，配比对氮氧混合气体的击穿电压影响较小，氮氧混合气体的击穿电压随充气压力的提高均呈增长趋势；棒—板电极下氮氧混合气体的击穿电压明显降低；针—板电极下氮氧混合气体的击穿电压在0.6~0.9 MPa出现“驼峰”效应，随着针—板电极间距增大，“驼峰”效应越发显著，较高气压下绝缘强度出现饱和。综合分析表明，在不同电场均匀度下，0.8 MPa时80%N2/20%O2与SF6在0.4 MPa时80%的绝缘强度相当。

少油断路器的新观念

Gaoya dianqi, 1960
该文主要是介绍法国最近试验的150千伏,800安,3500兆伏安少油断路器。它一相一个断点,利用压缩空气压油,这是它使用上的特征,其构造非常简单。 它的灭弧室内设置有几根压油管,开断时用压力油吹弧,使电弧强烈冷却而去游离化。下面有充氮气的贮气室,电动泵大约有80大气压的压力 ...
