摘　　要：在10kV配电线路送电过程中发现保护误动,通过在现场对配电线路进行合闸电流测试,发现在合闸过程中存在很大的合闸涌流。通过测试数据分析了合闸涌流的大小和特性,并分析了产生的原因和影响因素。分析了微机保护装置对合闸涌流误动的原因,提出了解决办法,并在生产现场应用,成效明显。In the paper, a very big on-off inrush in 10 kV distribution switching is presented, the values and characteristics of the on-off inrush from the measuring values are researched, the causes and factors are analyzed. An improved method is proposed to resolve the computer protection overreaching on distribution lines switching-off. Experimental results verify that the method is correct and effective.
