| Summary: | In view of problems that under-voltage electromagnetic releaser has low reliability and main circuit design scheme of common under-voltage releaser is easier to damage under-voltage releaser, an under-voltage releaser with high reliability based on capacitor depression voltage was designed. Design of main circuit, voltage signal sampling, frequency tracking, power circuit and discharge circuit of the releaser were introduced in details. The actual application shows that failure rate of the releaser is less than 1 ‰, and the releaser has higher reliability. |
