摘　　要：为了满足国家标准对断路器分闸脱扣器需满足电压动作极限值的要求,笔者对高压断路器分闸的动作电压限值做了简要介绍,高压断路器分闸的动作电压限值,比较了中国国家标准GB与国际电工标准IEC对此要求的差异以及由此产生的问题,并以HMB-1型操动机构的分闸线圈为例介绍了此类问题的解决思路,为解决同类技术问题提供了有价值的设计参考。In order to meet the requirements of voltage action limits in the national standard （GB） for circuit breaker trip release, this paper introduced the voltage action threshold of high-voltage circuit breaker trip release, compared the deviation between IEC and GB standards, and discussed the problems caused whereby. The method to solve the problems was described through an example of release coil in HMB-1 drive.
