Abstract

The invention discloses a frequency converter cabinet body with dustproof and moistureproof performance, comprising a support frame, a first plate body, a second plate body, an upper plate body, a lower plate body, a vent pipe, a controller, a fan, a filter screen, and a moisture absorption box, wherein the support frame is in a cuboid shape; the support frame is composed of an upper fixing frame,a lower fixing frame and a connecting column; the upper fixing frame and the lower fixing frame are both rectangular frame structures; the upper fixing frame is located directly above the lower fixing frame; four corners of the upper fixing frame and the four corners corresponding to the lower fixing frame are connected by the connecting column; and a top of the upper fixing frame is covered withthe upper plate body. According to the frequency converter cabinet body with dustproof and moistureproof performance, the cabinet body can be effectively air-cooled, and has the moistureproof and dustproof function by disposing the filter screen, the moisture absorption box and the fan with the two-way air blowing function in the vent pipe, and by changing the blowing direction of the fan, the moisture absorption box after moisture absorption can be weathered and dried under the action of hot air, so that the moisture absorption box keeps good moisture absorption capacity.

Description

【Technical field】 [0001] The invention relates to the technical field of frequency conversion machines, in particular to the technical field of frequency conversion cabinets. 【Background technique】 [0002] The frequency conversion machine is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The frequency conversion machine 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 conversion machine adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency conversion machine has many protection functions , such as overc...
