摘　　要：阐述传统的过欠电压保护器采用模拟器件、机械式、互感式,存在体积大、功耗高的问题,探讨一种新型过欠电压保护器的设计,该保护装置的特点是采用了一位双值转换电路,使磁保持继电器的线圈两端不会同时出现高电平,从而提高装置的可靠性。This paper describes the problems of large volume and high power consumption in traditional overvoltage and undervoltage protectors that use analog devices,mechanical devices,and mutual inductance.It explores the design of a new type of overvoltage and undervoltage protector.The characteristic of this protection device is the use of a dual value conversion circuit,which prevents high levels from appearing at both ends of the coil of the magnetic holding relay,thereby improving the reliability of the device.
