High-voltage inverter convenient to move

Abstract

The invention discloses a high-voltage inverter convenient to move. The high-voltage inverter convenient to move is simple and reasonable in structure, low in production cost, convenient to mount andcomplete in function. A moving device, with the damping function, special for the inverter is provided, the damping function is achieved, when the inverter is transported, the inverter is protected, the inverter is not prone to damage, and economic losses are reduced; a spring is arranged between a groove and a support, vibration can be effectively resisted, a handle is rotated, a clamping block clamps the inverter, shaking is prevented, damage in the transporting process is avoided, a hydraulic rod works, a lifting frame descends, a concave frame covers the inverter, the freedom degree of theinverter can be limited to a great degree, a rotating motor drives a rotating shaft to rotate, a first shaft sleeve and a second shaft sleeve move to achieve ascending and descending of the sliding rod, the height of the whole device is greatly adjusted, through motor ascending and descending, the inverter is stable and efficient, the inverter cannot be damaged, an air pressure rod extends out ofa universal wheel and is moved through the universal wheel, and after the air pressure rod is moved to the designated place, the air pressure rod retreats from the universal wheel.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a mobile high-voltage 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. [0003] 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 prote...

AI Technical Summary

Problems solved by technology

[0004] At present, the inverter is directly placed on the transportation equipment to transport the inverter. During the transportation, the inverter will be vibrated, which will easily damage the parts on the inverter; and the position of the inverter is not fixed, so it is easy to transport. In the event of a collision, the frequency converter is more likely to be damaged, resulting in economic losses. Therefore, it is urgent to develop a frequency converter that has a shock-absorbing function and is protected during the transportation of the frequency converter so that the frequency converter is not easily damaged and reduces economic losses.
