A kind of electrical equipment with good heat dissipation performance with the function of adjusting air pressure

Abstract

The invention relates to power equipment with an air pressure adjustment function and good heat dissipation performances, and the equipment comprises a main body and a door plate. The door plate is disposed at one side of the main body, and one side of the door plate is hinged to the main body. A heat dissipation mechanism is disposed above the main body, and a pressure adjustment mechanism is disposed below the main body. The heat dissipation mechanism comprises a water storage tank, a cooling pipe, a connecting pipe, a power chamber, and a power assembly. The pressure adjustment mechanism comprises a pressure adjustment box, a dust removing assembly, and a pressure adjustment assembly. The pressure adjustment box is fixed below the main body. The pressure adjustment assembly comprises adrive unit and a pressure adjustment unit, and the pressure adjustment unit comprises a push rod, a moving plate, a fixed plate, an opening, a cavity, a gas pipe, two limiting units, and two sealing units. The power equipment provided by the invention changes the gas pressure in the main body through the pressure adjustment mechanism, and can operate normally in a convenient way. Moreover, the heat dissipation mechanism is used for dissipating the head in the main body, and achieves the cooling function.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an electric equipment with the function of adjusting air pressure and good heat dissipation performance. Background technique [0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power distribution cabinets are a type of power equipment. Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. The power distribution cabinet is the general name of 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. The electrical energy distributed to the nearest load, this level of equipment should provide protection, monitoring and control of the load. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] When the existing power distribution cabinet operates in an area higher than 2000 meters above sea level, due to the high altitude, it will affect the arc extinguishing ability of electrical appliances. Arc is a form of gas discharge, which is affected by medium conditions. Due to the high altitude Higher, lower air pressure, more difficult to extinguish the arc, not only that, the existing power distribution cabinets use air cooling to dissipate heat, the thinner the air, the more difficult it is to dissipate heat, and the air in plateau areas is thinner, more difficult to dissipate heat
