Multi-purpose electrical cabinet special for frequency converter

Abstract

The invention discloses a multi-purpose electrical cabinet special for a frequency converter. The multi-purpose electrical cabinet is reasonable and simple in structure, low in production cost and convenient to install, and has complete functions; a rain cover is arranged, so that rain is effectively shielded; bird repelling mirrors and bird repelling bells are arranged for effectively repelling birds; the freedom degree of the electrical cabinet is limited through a clamping block, so that sliding of the electrical cabinet is effectively avoided; a fan is used for heat dissipation, and rainwater can be prevented from entering a ventilating chamber through a blind window; when the electrical cabinet does not work, air pressure rods drive an L-shaped frame to rise to block a vent hole for effective dust removal, a draft fan is used for drafting air, dust in the air is drafted out, the dust is adsorbed on an airtight conveying belt, and the dust in the airtight conveying belt is removedthrough clean water in a dust removal chamber; an anti-moving device is arranged, so that the stability of the whole device is improved; a locking device is further arranged in the electrical cabinet,other electrical elements can be clamped between a left clamp and a right clamp, and the multi-purpose electrical cabinet is achieved through the technical characteristics.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a multipurpose electrical cabinet dedicated to frequency converters. 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. [0003] The frequency converter 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 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, overvoltage, over...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a special multi-purpose electrical cabinet for frequency converters in order to solve the above problems, which solves the problem of single function of the current frequency converter electrical cabinets, poor heat dissipation effect, poor dustproof effect, and poor shock absorption effect. The mobile performance is inconvenient, and there are no problems with rainproof and bird repelling functions
