Under-voltage protection circuit structure of high-power generator load

The utility model discloses an under-voltage protection circuit structure of a high-power generator load. The under-voltage protection circuit structure comprises a generator, a generator controller and a low-voltage power distribution cabinet. The generator controller is electrically connected with the generator; the under-voltage protection circuit structure of the high-power generator load further comprises an intermediate relay and a low-voltage circuit breaker. The generator controller is electrically connected with the intermediate relay; the intermediate relay is electrically connectedwith the low-voltage circuit breaker; and the generator is electrically connected with the low-voltage power distribution cabinet through the low-voltage circuit breaker. The problems that the voltageoutput to a low-voltage power distribution room by a generator in the initial power supply stage is unstable and the load of a logistics center is easy to undervoltage burnout in the prior art are solved. 本实用新型公开了一种大功率发电机负载的欠
