High-heat-dissipation easy-to-carry power distribution cabinet based on injection and suction principle

Abstract

The invention provides a high-heat-dissipation easy-to-carry power distribution cabinet based on an injection and suction principle, and relates to the technical field of power equipment. The high-heat-dissipation easy-to-carry power distribution cabinet based on the injection and suction principle comprises a cabinet body, ventilation openings are formed in the left side and the right side of thecabinet body, a wind shield is rotatably connected to the interior of the ventilation opening, a gear is fixedly installed on the side, close to the interior of the cabinet body, of the wind shield,the inner side of the gear is engaged with a bending rod, a first spring is fixedly connected to the bottom end of the bending rod, and a lifting rod is fixedly installed in the center of the top endof the bending rod. The high-heat-dissipation easy-to-carry power distribution cabinet based on the injection and suction principle can extract and discharge the hot air at the top of the cabinet body, so that the heat dissipation effect of the cabinet body is improved; the cabinet body is sealed after the normal temperature is recovered, so that dust cannot enter the cabinet body, and normal power-on of an internal circuit is guaranteed; and the cabinet body can be carried conveniently, and meanwhile, operation of universal wheels is more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a high heat dissipation and easy-to-carry power distribution cabinet based on the ejection-absorption principle. Background technique [0002] The power distribution cabinet refers to the final equipment of the power distribution system such as the power distribution cabinet, the lighting distribution cabinet, and the metering cabinet. It is a general term for the motor control center. The center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads, and provide protection, monitoring and control for the loads. [0003] Since the lines in the power distribution cabinet are concentrated and dense, a large amount of heat will be generated during the working process. In order to ensure the normal power supply of ...

AI Technical Summary

Problems solved by technology

[0003] Since the lines in the power distribution cabinet are concentrated and dense, a large amount of heat will be generated during the working process. In order to ensure the normal power supply of the lines, the power distribution cabinet needs to have good heat dissipation performance, and the vents of the traditional power distribution cabinet are all opened. At the left and right ends, but the hot air generated will flow upwards, so the heat dissipation effect of the traditional power distribution cabinet is not good, and when the vent is always open, it is easy for dust to enter the interior of the power distribution cabinet, which is harmful to the line. In order to facilitate the transfer and handling of the power distribution cabinet, universal wheels are installed at the bottom of the traditional power distribution cabinet. However, in order to make the power distribution cabinet stable, the traditional universal wheels need to be moved manually. Contraction or stretching, the operation is cumbersome and laborious
