Gaoya dianqi, 2014 为了解决在进行GIS耐压试验时发生电击穿故障后击穿放电点难以精确定位的问题,对GIS的放电定位方法进行了归纳,并介绍了一种基于超声波检测法的GIS无线击穿定位系统,该系统具有定位效果好、安全可靠、抗干扰性能好、无线通信稳定等诸多优点。通过现场应用,准确定位了多起GIS设备内部击穿故障。

Gaoya dianqi, 1977 五、无重击穿少油断路器灭弧室结构设计要点。 如前所述,开断线路充电电流时,电弧分解的气体可能削弱灭弧室绝缘,引起触头间隙击穿、沿灭弧室内表面闪络、灭弧片击穿等现象,从而引起重燃。所以,从无重击穿的要求来看,灭弧室结构设计时,应注意下述各点。 1.应便于使电弧分解的气体 ...

Gaoya dianqi由于受各断口合闸操动分散性、触头表面状况迥异、真空间隙击穿电压的分散性等影响，双断真空断路器的关合预击穿现象往往表现为各断口的非同时预击穿。现阶段仍缺乏串联真空间隙的非同步关合预击穿特性相关研究，文中目标是实验研究双断口真空断路器非同步关合的预击穿开距和预击穿电压分布的特性。实验以两个串联连接的12 kV商用真空灭弧室为研究对象，设置4组关合实验条件：两个断口同步关合、低压侧比高压侧快1 ms关合、高压侧比低压侧快0.5 ms关合、高压侧比低压侧快0.2 ms关合 ...
