Abstract

The invention discloses an electric cabinet, a method and a device for modular combination of the electric cabinet. The electric cabinet comprises a filtering module used to filter interference signals of power signals and improve electromagnetic compatibility effect of the electric cabinet, a drive module used to drive a variable frequency motor and realize rotating speed adjustment of the variable frequency motor, a rectification inverse module used for converting power systems, and a master control module used to control loads to realize a control function of the electric cabinet. When a power system is not matched, the rectification inverse module performs voltage conversion. The electric cabinet solves a problem in the prior art that universality degree of an air conditioning controlmainboard is poor, and universality degree is improved, and rapid maintenance and changing can be realized.

Description

technical field [0001] The invention relates to the technical field of electric control equipment, in particular to an electric control box and a modular combination method and device for the electric control box. Background technique [0002] In order to suit different groups of people, there are various styles of air conditioners on the market. Especially in the field of army air conditioners, the appearance and size of air conditioners are even more strange. In order to better adapt to the car body itself, its specifications are determined by the car body itself. The common types are: integral air conditioner, split air conditioner, and roof-mounted air conditioner. Class air conditioners are divided into multiple types according to functions such as cooling only, heat pump, frequency conversion, and fixed frequency. Although the internal motherboards and control methods are mostly similar, they have various shapes. It takes a lot of time to design and develop each one i...
