Novel mobile wall-mounted frequency converter case

Abstract

The invention discloses a novel mobile wall-mounted frequency converter case comprising a frequency converter case body. Convenient lubrication limiting sliding devices are fixedly connected to four corners of the outer wall of one side, away from a case door, of the frequency converter case body; and the frequency converter case body is connected with a wall-mounted track by the convenient lubrication limiting sliding devices. A brake support plate is fixedly connected to the outer wall of the bottom of the wall-mounted track; and the outer wall of one side, away from the frequency convertercase body, of the wall-mounted track is fixedly connected with the wall surface. The invention relates to the technical field of related frequency converter equipment. The novel mobile wall-mounted frequency converter case is suitable for indoor factory rooms with high dust and indoor humidity. The frequency converter case can be mounted on the wall and can move up and down automatically, so thatthe frequency converter case can be stored at a high altitude, so that the space utilization rate is increased; and the dust accumulation amount and the moisture degree inside the frequency convertercase can be reduced.

Description

technical field [0001] The invention relates to the technical field of frequency converter related equipment, in particular to a novel mobile wall-mounted frequency converter chassis. 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), 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, overload...

AI Technical Summary

Problems solved by technology

[0003] Due to the wide range of use of frequency converters, the control boxes of frequency converters used in production plants are mostly fixed and installed on the wall or directly vertically. In order to ensure the heat dissipation effect inside the control box of the frequency converter, it is necessary to Ventilation and cooling ports are provided on the side of the box, but in a dusty or humid environment, when the inverter control box is installed at a lower position, not only the space utilization rate is reduced, but also the dust deposition inside the inverter control box is serious, and the humidity is relatively high. High, short circuit is easy to occur inside the inverter control box
