阻容均压方式下双断口真空断路器预击穿特性研究

Gaoya dianqi
双断口真空断路器能够充分利用短真空间隙的优异绝缘性能，显著降低容性电流开合过程中的重击穿概率，提高投切电容器组的性能。文中通过实验研究了双断口真空断路器采用阻容均压方式时的预击穿特性，包括预击穿电压、预击穿开距及其分散性，并计算其威布尔分布。研究结果表明，无论电压幅值如何，高压电阻都可以通过阻断从均压电容流向真空灭弧室的放电电流来延缓击穿过程，显著提升了双断口真空断路器的预击穿特性。对于串联电阻和桥接电阻两种阻容均压方式，桥接电阻可以减少电路中使用的电阻数量，降低断路器成本和体积 ...

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。
