Abstract

The invention relates to the technical field of frequency converter devices, and discloses a frequency converter capable of preventing high-temperature damage and a using method thereof. Through the arrangement of a temperature conduction wire and the like, when the temperature is higher than the rated temperature set by a central processing unit, the central processing unit starts a cooling system in time to cool the whole frequency converter to prevent the frequency converter from being burnt due to high temperature; by starting a motor, an input shaft rotates, then a driving gear rotates along with the input shaft, the driving gear drives a driven gear to rotate, and therefore a transmission shaft drives a transmission belt wheel to rotate, and by arranging a second transmission belt, the transmission shaft and a driven shaft drive two air-cooled heat dissipation fans to rotate correspondingly, and overall air-cooled cooling of the circuit bottom plate is achieved. And through the arrangement of a first transmission belt and the like, a cooling shaft drives a water tank heat dissipation fan to rotate, then the water tank heat dissipation fan conducts air cooling on cooling liquid, and therefore it is guaranteed that the cooling liquid keeps low temperature and is pumped back by a cooling pump to be recycled.

Description

technical field [0001] The invention relates to the technical field of frequency converter devices, in particular to a high temperature damage-resistant frequency converter 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. It is mainly composed of rectification, filtering, inverter, braking unit, drive unit, detection unit, micro-processing unit, etc. Composition, the inverter has many protection functions, such as overcurrent, overvoltage, overload protection, etc. The incoming terminal, rectifier bridge, energy storage capacitor, pre-charging circuit, inverter, current transformer, and outgoing terminal are necessary for the inverter. Then, to achieve frequency conversion, control power supply and main control board are also required; generally there ar...
