Abstract

The invention discloses an explosion-proof frequency converter. The explosion-proof frequency converter comprises a fixed box, wherein a damping device is fixedly connected to the bottom of the innerwall of the fixed box; a supporting plate is fixedly connected to the top of the damping device; the top of the supporting plate is fixedly connected with an explosion-proof box; vent holes are formedin the top of the explosion-proof box; a motor is fixedly connected to one side of the inner wall of the fixed box; the output shaft of the motor is fixedly connected with a threaded rod through a coupler; the surface of the threaded rod is in threaded connection with a moving block, and the bottom of the moving block is fixedly connected with a first rack; and the surface of the first rack is meshed with a gear. The invention relates to the technical field of frequency converters. By virtue of the explosion-proof frequency converter, the problem that a current frequency converter cannot wellperform heat dissipation is solved, so that the damage and explosion risks of the frequency converter are reduced, unnecessary troubles are avoided for people, the economic loss is reduced, and the frequency converter is well protected.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to an explosion-proof frequency converter. 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, filtering, inverter, braking unit, drive unit, and detection unit. And other components, 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 over-current, over-voltage, overload protection and so on. With the continuous improvement...
