Heat dissipation device for high and low voltage switch cabinet

Abstract

The invention discloses a heat dissipation device for high and low voltage, comprising a base, the top of the base is fixedly connected with a switch cabinet body, the top of the switch cabinet body is fixedly connected with a transmission box, and one side of the inner wall of the transmission box The motor is fixedly connected through the connecting block, the outer surface of the output shaft of the motor is covered with a first bevel gear, and the top and bottom of the inner wall of the transmission box are connected with the first transmission shaft and the second transmission shaft through bearings in turn from left to right. drive shaft and third drive shaft. The invention relates to the technical field of electrical equipment. The heat dissipation device for high and low voltage switchgears achieves high-efficiency heat dissipation for the switchgear, greatly enhances the heat dissipation effect, and realizes the timely operation of the electrical components inside each individual box. The generated heat is dissipated, which ensures the normal operation of the electrical components inside the high and low voltage switchgear, thereby prolonging the service life of the electrical components inside the high and low voltage switchgear.

Description

Technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a heat dissipation device for high and low voltage switch cabinets. Background technique [0002] High and low voltage switch cabinets are equipment for connecting high voltage or low voltage cables. Generally, power supply bureaus and substations use high voltage cabinets, which are then stepped down by transformers to low voltage cabinets, and low voltage cabinets to various power distribution boxes. Low-voltage switchgear is nothing more than a piece of electrical equipment that assembles some protective devices such as switch and circuit breakers into one, and its application is very wide. [0003] The current high and low voltage switch cabinets are mostly composed of multiple sealed cabinets fixedly installed with each other. When in use, each individual cabinet in the switch cabinet will generate higher heat. However, the current high and low voltage switch cabinets ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a heat dissipation device for high and low voltage switch cabinets, which solves the problem that the heat dissipation effect is poor and the heat generated by the electrical components inside each individual box cannot be dissipated in a timely manner.
