| description | The invention provides a device for preventing an under-voltage tripping control module of a low-voltage switch from being damaged and a use method, and belongs to the technical field of power circuit breaker guarantee. The device comprises a lightning protection module, a voltage stabilization module, an under-voltage detection module, a power-off time delay module and a power transmission time delay module; the lightning protection module is hung on the alternating current bus; the output end of the lightning protection module is connected with the voltage stabilization module, and the output end of the voltage stabilization module is connected with the under-voltage detection module, the power-off time delay module and the power transmission time delay module. And the output end of the under-voltage detection module is connected with the power-off delay module. The under-voltage tripping controller module is protected from being damaged by lightning stroke through a protection line, harmonic wave resistanc |
