Heat dissipation frequency converter

Abstract

The invention discloses a heat dissipation frequency converter. The heat dissipation frequency converter comprises a box body and a frequency converter body, a mounting seat is arranged at the bottom in the box body, the frequency converter body is mounted on the mounting seat, a damping assembly is arranged at the bottom of the box body, a high-temperature detection assembly is arranged at the bottom of the frequency converter body, a heat dissipation assembly is arranged in the box body, the high-temperature detection assembly is in control connection with the heat dissipation assembly, the right side of the box body is provided with heat dissipation holes and is detachably connected with a dustproof net. By arranging the damping assembly, the damping effect can be achieved, the frequency converter body is prevented from being damaged due to vibration, meanwhile, the high-temperature detection assembly is arranged, when the temperature in the box body is too high, the high-temperature detection assembly controls the heat dissipation assembly to work, heat dissipation is conducted on the interior of the box body, heat generated by the frequency converter body can be dissipated out through the heat holes, the dustproof net can play a dustproof role, dust is prevented from entering the box body through the heat dissipation holes, drying agent particles in the containing box can play a drying role, and the interior of the box body is prevented from being moist.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a heat dissipation frequency converter. Background technique [0002] Inverter (Variable-frequency Drive, VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating 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 protection and so...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, an overcurrent protection device is generally installed when the frequency converter is used to ensure the normal use of the frequency converter. The installation position is fixed, which will lead to a general heat dissipation effect. When the inverter is used for a long time, it will have a certain impact on the service life of the inverter due to the difficulty in dissipating heat.
