High-efficiency heat-dissipation power distribution cabinet

Abstract

The invention relates to the field of power equipment, in particular to a high-efficiency heat-dissipation power distribution cabinet. The high-efficiency heat-dissipation power distribution cabinet comprises a vertically arranged supporting and mounting barrel, wherein a supporting and mounting plate is horizontally arranged under the supporting and mounting barrel; a rotating door is rotationally arranged at the right end of the supporting and mounting barrel through a hinge; a plurality of heat dissipation holes are uniformly formed at the wall of the supporting and mounting barrel; a limiting rotating column is vertically arranged in the middle portion of the inside of the supporting and mounting barrel; a limiting mounting sleeve is arranged at the top of the supporting and mounting barrel in a manner of matching with the limiting rotating column, through the three-dimensional multilayer mounting structure, the mounting quantity of the power elements of the device is obviously increased, and the heat is dissipated by porous uniform diversion, diversion small cage package is controlled by cooperating with a guide lifting structure so that the inside heat dissipation efficiencyis controllable, the axial rotation shifts so that the inside power component homoenergetic of device is maintained quickly, and the radiating efficiency and the operating stability of the power distribution cabinet are obviously improved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a high-efficiency heat dissipation power distribution cabinet. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control 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 nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] At present, the outer box of the exis...

AI Technical Summary

Problems solved by technology

[0003] At present, the outer box of the existing power distribution cabinet has poor heat dissipation function. When the factory uses the high and low voltage power distribution cabinet for a long time, it is easy to cause certain safety hazards due to the high temperature, which makes the internal parts damaged during operation.

[0004] Chinese patent (notification number CN208908315U) discloses a power distribution cabinet with ventilation and heat dissipation. Although it can perform ventilation and heat dissipation, the internal mechanism adopts an integrated installation structure, which has low space utilization, and the heat dissipation adopts a large channel blowing structure, which has low heat dissipation efficiency.
