Gaoya dianqi, 1983 高压断路器的分、合闸速度,对开断性能的影响很大。已有的测量断路器分、合闸速度的方法虽很多,但多适用于测量较大开距的断路器,如油断路器、空气断路器和六氟化硫断路器等。对于开距较小的真空断路器来说,上述测量装置均不适用。过去,由于我们一般只能测量真空断路器的平均分、合闸速度,因而对其全部行程的速度特征和缓冲性能,都不能作深入的分析和测量。

Gaoya dianqi, 1972 1.引言 已往,关于真空电弧基本特性的文献多局限于数千安以下。随着真空断路器的迅速发展,有必要对更大电弧电流的真空电弧作一基本的研究。在大功率输配电系统中,要求断路器开断60千安左右的电流(有效值),因而真空断路器也就要求能开断这样的电流。
