摘要
为寻找真空断路器投切电容器组时发生爆炸的原因 ,在运行电网上进行了 10kV真空断路器投切电容器组的试验。 5组样机为不同批号和洁净度的真空灭弧室 ,将其安装于同一组真空断路器上投切同一组电容器组。通过分析试验结果 ,得出结论 :爆炸原因是真空断路器投切电容器组时发生重击穿并产生较高的过电压 ;真空灭弧室内部洁净度是影响真空断路器投切电容器组重击穿率的重要因素 ;真空断路器在投运前进行 5
This paper introduces the opening closing capacitor experiment of 10 kV vacuum circuit breaker taken under the running power system. The conclusion is that it re striked and produced higher overvoltage in the time of opening closing;it verifies the fact that cleanliness of the arc interrupter is very essential for the re strike rate of the vacuum circuit breaker.
