Frequency converter with moisture-proof mechanism and use method thereof

Abstract

The frequency converter comprises a supporting bottom plate and a frequency converter body, a middle shell is fixedly connected to the middle of the top of the supporting bottom plate, the left side and the right side of the middle shell are open, a movable door is installed on the front side of the middle shell, and a lower shell is arranged at the position, close to the bottom, in the middle shell in a sleeving mode; an opening is formed in the top of the lower shell, the bottom of the lower shell is fixedly connected with the top of the supporting bottom plate, a placing plate is fixedly connected to the position, close to the top, between the inner walls of the left side and the right side of the lower shell, and the frequency converter body is placed on the top of the placing plate; through mutual cooperation of the pressing plate, the pipe body, the guide pipe, the moisture-proof sponge, the storage box and other components, water vapor or water flow in the moisture-proof sponge can be recycled, the purpose of saving resources is achieved, and meanwhile, through arrangement of a circulating pipe, a thick pipe, a buoyancy ball, a trigger block and the like, auxiliary heat dissipation and warning effects on the frequency converter body can be achieved.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter with a moisture-proof mechanism and a method for using the same. Background technique [0002] The frequency converter 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 converter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking Unit, drive unit, detection unit micro-processing unit and so on. The frequency converter 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 converter has many protection functions , such as overcurrent, o...

Problems solved by technology

[0003] At present, the damp-proof efficiency of inverters on the market is staggered when used, and it cannot effectively reuse the water vapor or water flow generated after moisture-proof, which leads to waste of resources and reduces its use efficiency. Therefore, we propose a Inverter with moisture-proof mechanism and its application method
