In order to improve the reliability of electromagnetic type undervoltage release,based on the deficiency analysis of the existing scheme,a new scheme of a reliable electromagnetic undervoltage releaser is proposed by op-timizing structure of main circuit. With the new scheme,the specific analysis and design of main circuit,single-chip microcomputer circuit and power circuit are demonstrated. Experiments show that the new scheme has the advantages that the overall power consumption of the new scheme circuit itself is only milliwatts and the accuracy of action point is limited within plus or minus 2 V while the cost is quite low. The scheme has successfully passed the 1. 3 times rated voltage aging test and the 4 kV EFT test.
