摘要
通过对小型断路器电磁脱扣器电磁吸力的计算分析,选择不同磁轭以找到合适的电磁吸力值,解决电磁吸力与反力弹簧的配合问题,提高了电磁脱扣器动作灵敏度与一致性。
On the basis of calculation and analysis for electromagnetic suction of electromagnetic tripping device of miniature circuit breaker,different magnetic yokes were chosen to find the suitable electromagnetic suction value, in order to solve the problem of coordination between electromagnetic suction and the force of spring, to improve the electromagnetic tripping device action sensitivity and consistency.
