Novel auxiliary device for starting generator set at low temperature

The utility model discloses a novel auxiliary device for starting a generator set at the low temperature. The novel auxiliary device comprises a diesel oil engine, a temperature sensor, a water jacket heater and a controller. The diesel oil engine comprises a water outlet header pipe and a water inlet header pipe. One end of the temperature sensor is arranged on the water inlet header pipe, and the other end of the temperature sensor is connected with the controller. The controller is connected with the water jacket heater. The water jacket heater is connected to the water outlet header pipe. The water outlet header pipe, the water inlet header pipe, the temperature sensor, the controller and the water jacket heater form a loop. The temperature sensor, the water jacket heater, the controller and the like are used cooperatively, it can be ensured that the temperature of the generator set is kept in the optimal working temperature range of 20 DEG C-40 DEG C, and the problem that a diesel oil generator can not be started fast when the environment temperature is low is solved.
