VD4真空开关组装分析与探索

Analysis and Exploration of the Assembling of VD4 Vacuum Switch

高压开关运行超限导致废旧率持续升高,通过对废旧开关的检查,发现两台35 kV真空废旧开关的故障有互补性,通过"一测一调"分析法进行调试,成功把两台废旧开关组装修复,通过试验检测,该开关各项指标均符合使用要求,为今后开关组装奠定基础。

Overrunning operation of high-vohage switches led to rising scraping rate. Through checking of scraped switches it was found that the faults of lwo scraped 35 kV vac- uum switches were supplementary to each other and the switches were successfully reassem- bled and restored using the ＂test and adjustment＂ analysis method. Test and measurement showed that the switches indicated qualified index, laying the basis for switch reassembly in the future.
