Problems solved by technology

In the process of realizing the present invention, the inventor found that the cooling method of the frequency converter in the prior art has the following problems: when the cooling air passes through the cover of the frequency converter, it will simultaneously sweep the heat sink side and the component integration side of the frequency converter, so that When the generator set is used under the condition of rain or high air humidity, the cooling wind may carry rainwater or water droplets into the component integration side of the inverter and adhere to the components, which may cause damage to the components; at the same time, the air The dust and other tiny particles in the air will enter the component integration side with the cooling air, and some of them will adhere to the components. Over time, the dust and other tiny particles adsorbed and accumulated on the components will gradually increase, which may affect the performance of the components. Negative Effects

Abstract

The invention relates to a variable-frequency generator unit. The variable-frequency generator unit comprises an engine and an electric generator driven by the engine; the engine is provided with a fan cover for accommodating a cooling fan; the variable-frequency generator unit is characterized by further comprising a frequency converter, a frequency converter cover for accommodating the frequencyconverter and a flow guide cover, wherein a frequency converter air inlet and a frequency converter air outlet are formed in the side, facing towards a frequency converter cooling fin, of the frequency converter cover; and the flow guide cover is used for an air flue from the frequency converter cover air outlet to the fan cover, so that the variable-frequency generator unit is conducive to ensuring frequency converter and engine cooling, is conducive to water and dust prevention of frequency converter components, is conducive to reducing, even avoiding damage to the frequency converter components by dust, rainwater, water spray and the like, and is conducive to enabling wind to enter smoothly and reducing wind noise.

Description

technical field [0001] The invention relates to the field of generators, in particular to a variable frequency generator set. Background technique [0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It is composed of a power system, fuel system, rack system, power generation system, control system, exhaust system, etc. The frequency conversion generator set is also equipped with a frequency converter. In the existing engine-driven variable frequency generator sets, the frequency converter is placed in the frequency converter cover and arranged opposite to the fan cover, so that cooling air enters the frequency converter cover to realize cooling of the frequency converter. In the process of realizing the present invention, the inventor found that the cooling method of the frequency converter in the prior art has the following problems: when the cooling air passes through the cover of the frequency conv...
