Problems solved by technology

[0002] At present, there are various designs of frequency converters. Some frequency converters have poor heat dissipation performance due to the unreasonable layout of internal components. Capacitor bursting, etc., which greatly affect the service life of the components and the safety of the inverter; some inverter designs can only complete a single function, so when it is necessary to use new energy to achieve AC motor speed regulation and grid-connected power generation At the same time, it is necessary to use frequency converters with two functions at the same time, which causes the problems of high price and large area occupation of the frequency converter when it is used, resulting in waste of resources; in addition, the existing frequency converters still have unreasonable general assembly, It is not easy to expand and maintain problems, which not only increases the production cost of the frequency converter, but also increases the assembly cost of the internal components of the frequency converter

Abstract

The invention discloses a frequency changer which comprises a cabinet, a modularized component and a radiator component. The modularized component is arranged in the cabinet, the radiator component is arranged outside the cabinet, the modularized component comprises an alternating-current branch device set, a direct-current branch device set, an electrical device set and a power device set, the cabinet is divided into a first cabinet and a second cabinet through a partition, the first cabinet is used for containing the alternating-current branch device set, and the second cabinet comprises a first area used for containing the electrical device set, a second area used for containing the power device set, and a third area used for containing the direct-current branch device set. The modularized component is arranged reasonably, so that the frequency changer is enabled to be more reasonable and compact in assembly structure and easy to expand, maintain, manufacture and mount. In addition, power grid composite power supply and grid-connected power generation of the frequency changer can be realized, and the frequency changer has needed using functions and is good in heat radiating performance.
