Technical Field

The invention relates to the field of frequency converter case hoisting, in particular to a frequency converter case hoisting structure.

Background

The frequency converter is an electric control device which applies a frequency conversion technology and a microelectronic technology and controls an alternating current motor by changing the frequency mode of a working power supply of the motor. The frequency converter mainly comprises a rectifying unit (alternating current to direct current), a filtering unit, an inverting unit (direct current to alternating current), a braking unit, a driving unit, a detection unit micro-processing unit and the like. The frequency converter adjusts the voltage and frequency of an output power supply by switching on and off an internal IGBT, provides the required power supply voltage according to the actual requirement of the motor, and further achieves the purposes of energy saving and speed regulation.
