Cabinet for frequency converter and frequency converter

Abstract

The invention relates to a cabinet for a frequency converter and the frequency converter. The frequency converter comprises a rectification module, a filtering module connected with the rectification module, an inversion module connected with the filtering module and a control unit connected with the inversion module. Wherein the cabinet comprises a cabinet body, a cabinet door, an accommodating space formed between the cabinet body and the cabinet door, and a spacing member which is arranged in the cabinet body and divides the accommodating space into an upper cavity and a lower cavity, the upper cavity is used for installing the control unit, and the lower cavity is used for accommodating the rectification module, the filtering module and the inversion module. Heat generated by the rectification module, the filtering module and the inversion module can be effectively prevented from being absorbed by electrical apparatus elements in the control unit, the probability that the electrical apparatus elements in the control unit are aged or fail due to too high heating is reduced, and the service life of the frequency converter can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of frequency converters, and in particular relates to a cabinet for frequency converters and a frequency converter including the cabinet. Background technique [0002] With the continuous progress and development of electronic technology, the frequency converter technology is also gradually improving, but due to the large number of heat-generating components in the frequency converter (such as rectifier modules, filter modules, inverter modules and control units) and some parts are not reasonable enough, resulting in The electrical components in the control unit are prone to aging or failure due to overheating, which in turn affects the life of the inverter. Contents of the invention [0003] In order to solve all or part of the above-mentioned problems, the purpose of the present invention is to provide a cabinet for frequency converters and a frequency converter including the cabinet, which solves the pr...
