摘　　要：通过建立了微型断路器脱扣器中螺管电磁铁的有限元模型及运用有限元法,计算脱扣器在最大气隙微型断路器下,电流为触动电流时衔铁所受吸力,并利用计算出的吸力来反推弹簧参数。仿真试验表明,该方法是可行的。The finite element model of solenoid electromagnet in miniature circuit breaker release was established.When the release was under the maximum air gap,and current was touch current,using finite element method,the suction of the armature was calculated.The obtained suction was used to push the spring parameter.Experiments showed that the method was feasible.
