Embodiment Construction

[0015] Refer to figure 1 , The present invention is a variable frequency cabinet cabinet with adjustable heat dissipation, comprising a bottom plate 1, a column 2, a connecting rod 20, an outer cover 3, a top plate 4, a fan 31, a lifting column 40, a gauze ring 41, and a control device 5. The bottom plate 1 is a rectangle, each of the four corners of the upper end surface of the bottom plate 1 is fixed with a column 2 and the top ends of the columns 2 are connected by connecting rods 20. There are four connecting rods 20, four connecting rods 20 and four pillars 2 The top ends together constitute a rectangular frame. The outer cover 3 is a rectangular parallelepiped cover with both upper and lower ends open. The outer cover 3 surrounds the four uprights 2, and the outer cover 3 is fixed to the upright 2 and the connecting rod 20 by a number of screws. Fans 31 are fixed on the outer walls of the left and right sides of the outer cover 3, and air inlet windows 30 matched with the...

Abstract

The present invention discloses a frequency converter cabinet body with adjustable heat dispersion. The frequency converter cabinet body comprises a bottom plate, stand columns, connection rods, an outer cover, a top plate, fans, lifting columns, a yarn loop and a control device. The bottom plate is rectangular, the stand columns are respectively fixed at four corners of the upper end face of thebottom plate, the connection rods are connected between the top ends of the stand columns, there are four connection rods, the four connection rods and the top ends of the two stand columns commonly form a rectangular frame body, the outer cover is a rectangular cover body with openings at the upper and lower ends, the outer cover encloses the four stand columns, the outer cover is fixed with thestand columns and the connection rods through a plurality of screws, the fans are fixed on the outer walls of the left and right sides of the outer cover, the side walls of the left and right sides ofthe outer cover are provided with air inlet windows cooperated with air outlets of the fans, the top plate is located at the upper portion of the outer cover, and the top portions of the four stand columns are respectively embedded with the lifting columns with power devices. Through cooperation of the lifting columns and the top plate, the heat dispersion of the cabinet body is adjustable.

Description

【Technical Field】 [0001] The invention relates to the technical field of frequency conversion machines, in particular to the technical field of frequency conversion cabinets. 【Background technique】 [0002] Frequency conversion machine 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 working power supply. The frequency conversion machine is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro processing unit. The frequency conversion machine adjusts the voltage and frequency of the output power supply by the opening and closing of 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 conversion machine has many protection functions , Such as overcur...
