Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a high-performance vector frequency converter. Background Art

[0002] A high-performance vector inverter is a device that converts the power supply frequency into an adjustable output frequency to control the motor speed. Its core principle is vector control based on the DQ axis theory. By decomposing the motor current into D-axis current and Q-axis current, the motor model is decoupled. This inverter has many advantages, such as fast response, large starting torque, high efficiency and energy saving, etc. Specifically, the vector inverter can quickly adjust the motor operating state and is suitable for various applications in industrial automation and modern production, such as cargo bundling, welding and sewage pumps.

[0003] Some high-performance vector inverters currently on the market: for example, the utility model patent with authorization announcement number CN212572360U discloses a high-performance vector inverter, which uses a soft suction cup to quickly adsorb and fix the device to the fixed surface by pressing, and uses an air pump and air pipe to evacuate the soft suction cup to enhance the adsorption force, firmly attach to the surface of the fixed surface, and lock the soft suction cup through the fixed plate to prevent air leakage, so as to quickly and stably complete the device fixation. However, since the installation and fixing method of the inverter is relatively single and only has an adsorption and fixing installation method, the suction cup adsorption and fixing installation method is difficult to apply to walls with uneven surfaces and pores, and cannot be applied to installation in various environments, and has great limitations.

[0004] So we proposed a high-performance vector inverter to solve the above problems. Utility Model Content

[0009] Furthermore, a first dustproof net is arranged at a position on the side of the inverter body corresponding to the fan cavity, and a second dustproof net is arranged at a position on the top of the inverter body corresponding to the ventilation hole.
