BVAC.N99系列真空断路器主触头电阻值超差分析及改进措施

Error analysis and improvement measures about the main contact's resistance values of the BVAC.N99 series vacuum breaker

针对BVAC.N99系列真空断路器运用和二年检、四级修检修情况,对BVAC.N99系列真空断路器真空开关管导通后主触头电阻值超出了给定参数200μΩ进行了详细分析,并提出了相应的改进措施和改善真空开关管导通阻值处理方法。

This paper aims at application,two years overhaul and level four maintenance of BVAC. N99 series vacuum circuit breaker, after conducting the main contact resistanee value over a given parameter of 200 μΩ conducted a detailed analysis of the BVAC. N99 series vacuum breaker vacuum switch tube, and improvenment measures were put forward to improve the vacuum switch tube conduction resistance of the corresponding processing method.
