Description

Technical Field

[0001] The utility model relates to the technical field of vector frequency converters, in particular to an advanced vector frequency converter. Background Art

[0002] Vector inverter technology is based on the DQ axis theory. Its basic idea is to decompose the motor current into D-axis current and Q-axis current, where the D-axis current is the excitation current and the Q-axis current is the torque current. In this way, the excitation current and torque current of the AC motor can be controlled separately, making the AC motor have control characteristics similar to those of the DC motor, greatly improving the control characteristics of the AC motor.

[0003] However, current vector inverters will generate a lot of heat during use, which will cause the internal temperature of the vector inverter to be too high, thus affecting the normal operation of the vector inverter. Therefore, we propose an advanced vector inverter to solve the above problem. Utility Model Content

[0008] Preferably, the blowing drive mechanism includes a motor, a driving rod and driving blades. The motor is fixedly installed in the mounting frame, one end of the driving rod is fixedly installed on the output shaft of the motor, and the other end of the driving rod is fixedly installed with the driving blades, so as to facilitate the delivery of external air into the air guide circular groove through the air inlet.

[0009] Preferably, the spoiler mechanism includes a bracket and spoiler blades, the bracket is fixedly installed at the air outlet end of the diverter slot, and the spoiler blades are rotatably installed on one side of the bracket.

[0010] Preferably, a first dustproof net is provided in the air inlet, and the first dustproof net is located above the motor to prevent dust and impurities in the external air from entering the vector inverter case through the air inlet.

[0011] Preferably, the two air outlets on the vector inverter housing are symmetrically arranged, and a second dustproof net is arranged in the air outlet to prevent dust and impurities in the external air from entering the vector inverter housing through the two air outlets.

The bracket 11 is fixedly installed at the air outlet end of the diverter groove 5, and a spoiler blade 12 is rotatably installed on one side of the bracket 11. By providing a spoiler mechanism at the air outlet ends of the plurality of diverter grooves 5, the air delivered to the vector inverter case 1 is turbulent, which facilitates the uniform delivery of air to the vector inverter case 1; two air outlets 13 are respectively provided on the top sides of the vector inverter case 1.

[0021] Furthermore, the air inlet 3 is connected to the air guide circular groove 4, and a diverter plate 10 is fixedly installed on the bottom inner wall of the air guide circular groove 4. The diverter plate 10 diverts the air delivered to the air guide circular groove 4, so that the outside air is delivered to the air inlet ends of multiple diverter grooves 5 from the left and right directions respectively, and then enters the vector inverter case 1 through the air outlet ends of multiple diverter grooves 5.
