Abstract

A frequency converter for a generator set according to the invention comprises a casing, wherein a side wall of the casing is provided with a control panel and a binding post, and the upper end surface of the casing is provided with a plurality of heat dissipation holes; and a radiator disposed on the other side wall of the casing and including a box body filled with an insulating coolant, whereinthe box body comprises a left end cover and a right end cover which are connected through an insulating strip, the left end cover is connected to 0V ground, the right end cover is grounded, the outerwall of the left end cover is provided with a heat conduction silicone grease layer, a shielding layer is disposed in the middle of the heat conduction silicone grease layer, the shielding layer is connected to the 0V ground, and a side of the heat conduction silicone grease layer away from the box body is fixedly connected with the side wall of the casing. The frequency converter for the generator set has higher heat dissipation efficiency and is resistant to electromagnetic interference.

Description

technical field [0001] The invention belongs to the technical field of frequency converters, and in particular relates to a frequency converter for a generator set. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the alternator by changing the power frequency. The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter adjusts the voltage and frequency of the output terminal by switching off the internal IGBT, and provides the required voltage and frequency according to the actual needs of the generator, thereby achieving the purpose of energy saving and speed regulation. The existing frequency converter often causes failure of the frequency converter due to poor heat dissipation, which affects the normal operation of the freq...
