摘　　要：近年来,预付费电能表使用损坏频次呈缓慢上升趋势,其主要原因是设备运行环境不稳定和客户私自调试操作导致,造成预付费电能表使用寿命大幅度缩短和设备资源浪费。基于此,结合实际案例分析,设计出一种能够在延时时间到达后,输出脉冲信号经过零输出控制模块的晶闸管断开脱扣线圈电源的装置,可以达到线圈短时间得电的目的,减少线圈的送电时间,以此解决客户在负控处于通电状态的情况下,频繁合闸造成负控继电器及跳闸开关线圈烧毁的问题。In recent years,the damage frequency of prepaid meters is increasing slowly,because of the unstable operating environment and the private debugging by customers,so the lifespan of the prepaid meters is greatly shortened and the equipment resources are wasted.Based on this,an anti-burn device is designed that can disconnect the power supply of the tripping coil through the thyristor of the zero-output control module after the delay time is reached.The coil can be energized for a short period of time to reduce the power-on time.Therefore,the burning of the negative control relay and the tripping switch coil is solved,caused by frequent closing of meter when the negative control is in the energized state.
