摘　　要：归纳了在预试环节中出现的断路器分、合闸电磁铁最低动作电压变化的原因。通过对国内外文献的研究,由电磁铁动特性理论提出了针对最低动作电压进行在线监测的关键参数。经过初步的实验证明了这些关键参数的提取,对于有效地监测最低动作电压具有有效的作用。This paper summarized the reasons of the lowest action voltage change on the circuit breaker closing electromagnet in thepre-test link. Through the study of literature at home and abroad, put forward the key parameters of on-line monitoring to the lowestaction voltage based on the electromagnet dynamic characteristic theory. Preliminary experiments showed these key parametersextraction had effective function for monitoring of the minimum action vohage.
