大功率纵磁场真空断路器的大电流加速电寿命试验的研究
摘要
通过对国产10kV/630A/20kA真空断路器实际电寿命试验以及大电流开断试验
研究了大功率纵磁场真空断路器采用大电流加速电寿命试验方法的可行性
试验及理论分析表明
对于纵磁场真空断路器采用大电流加速电寿命试验不仅方法可行
而且还能由短路电流分断次数推算出等效额定电流下的操作次数来。
Abstract
The possibility of life test of axial magnetic type vacuum switches by high current acceleration has been investigated. The test result and the theoretical analysis show that not only this test method is utilizable but also an equivalent switch life at rated current can be calculated fromnumber of short-circuit current breaking.
