摘要
本文通过对10kV商用真空断路器在额定电压及额定电流下所进行的一定次数的电寿命试验,得到了高电压下真空电弧的弧压值及运用降低电压法时所需弥补的试验次数n,在此基础上,将试品在364V/630A下进行10~4+n次的电寿命试验,所得到的试验结果与额定电压下实测的基本相同,从而从实验的角度进一步证实了降低电压法与全电压法基本是等价的。
The equivalence of electric endurance test for 10kV vacuum circuit breaker between rated and reduced voltage has been confirmed by mean of the same results of several tests under rated voltage and 104 +n tests under 364V approximately. The increased testing number of reduced voltage test, n, could be calculated out with the rated voltage.
