Device for freezing prevention and heat preservation of generator set in winter

Abstract

The invention relates to a device for freezing prevention and heat preservation of a generator set in winter. The device comprises a box body and the generator set arranged in the box body, wherein the generator set comprises an engine and a generator driven by the engine, an anti-freezing system is arranged on the generator set, the anti-freezing system comprises a radiator arranged on the outer side of a rotor of the generator set, a corresponding fan is arranged on the inner side of an air inlet of the radiator, the fan is installed on the rotor of the generator set and used for rotationally feeding air, a heating belt is arranged between the inner side of the air inlet of the radiator and the fan, so that heat emitted by the heating belt heats air and is transmitted to the generator set in an accelerated mode through the fan, and normal starting and operation of the generator set in a cold environment are ensured. According to the device, the anti-freezing system capable of automatically monitoring and starting in the closed generator set can be adopted in cold seasons and regions so as to adapt to the cold application environment, and it is guaranteed that the generator set can be normally started and run in the low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to a device for winter antifreeze and heat preservation of a generating set. Background technique [0002] Diesel engine structure generator sets have a wide range of applications, such as: unit backup power supply, field operations, emergency power, disaster relief, large ships, yachts and vehicles with their own power supply, mobile communication base stations and many other occasions. [0003] The diesel engine drives the generator set to generate electricity, and the inverter converts the electricity generated by the generator into a stable single-phase power supply. However, when the working environment of the diesel engine, generator and inverter is relatively harsh, such as the ambient temperature in cold seasons It can reach -50°C. The internal temperature of the diesel generator set in the prior art is the same as the external ambient temperature when th...

[0003] The diesel engine drives the generator set to generate electricity, and the inverter converts the electricity generated by the generator into a stable single-phase power supply. However, when the working environment of the diesel engine, generator and inverter is relatively harsh, such as the ambient temperature in cold seasons It can reach -50°C. The internal temperature of the diesel generator set in the prior art is the same as the external ambient temperature when the diesel generator set is stopped. When the external ambient temperature is too low, the generator set cannot be started and operated normally. antifreeze measures
