摘　　要：分析电子式剩余电流保护器产品故障的原因,提出其脱扣电磁铁可靠性提高的必要性。通过脱扣电磁铁的改进设计以及关键参数的计算,得出改进后参数。采用仿真方法验证此改进设计方案的效果。通过试验对装有改进后脱扣电磁铁的产品进行验证,验证其性能达到设计指标和可靠性要求。Analysis was made on the failure model of residual current operated protective device, and the root cause is the failure of electronic relay inside. Research was taken to improve the parameters of the relay. Simulatiotl was done and the result could meet the goal. The tests result of the products with this new relay shows the improvement of reliability was obvious.
