Abstract

The invention discloses a cooling system of a variable frequency generator. The cooling system comprises an engine case, a generator, a generator shell, a fan blade, a generator rear cover, an insulation board, an inversion controller and a generator crankshaft, wherein the generator comprises a generator rotor and a generator stator; the generator rotor is arranged on the generator crankshaft; the generator shell is fixed on the generator case; the generator stator is fixed on the generator shell and is positioned in the generator rotor; the fan blade is positioned between the generator rotor and the generator rear shell; and the inversion controller and the insulation board are positioned on two sides of the generator shell respectively. The fan blade rotates to generate strong wind pressure, and cold air is sucked, and is discharged from an air outlet of the generator shell after fully cooling the generator stator and the generator rotor, so that the inversion controller, the generator case and the insulation board are compulsively cooled.

Description

technical field [0001] The invention relates to a variable frequency generator, in particular to a cooling system for a variable frequency generator. Background technique [0002] At present, permanent magnet generators are widely used in frequency conversion generators on the market. When this generator outputs high power, both the stator and the rotor will generate a lot of heat. If the heat cannot be taken away in time and quickly, the insulation performance of the stator will be destroyed and the magnet on the rotor will be demagnetized, thereby reducing the service life of the generator and affecting the performance of the generator. At present, the cooling method of the frequency conversion generator usually adopts to place the engine and the generator in a sealed space, use a cooling fan, and place the frequency converter at the front end of the fan. This structure makes the generator and the engine share a cooling air road. Because the temperature of the box and th...
