High-voltage power cabinet with good heat dissipation effect

Abstract

The invention relates to the technical field of power cabinets, in particular to a high-voltage power cabinet with a good heat dissipation effect. The cabinet comprises a cabinet body, a PLC is fixedon the upper side wall of the cabinet body, air inlet hoods are arranged above the two side walls of the cabinet body, and air exhaust hoods are arranged below the two side walls of the cabinet body;air can be conveniently fed through the arranged air inlet hoods when a draught fan rotates, the air inlet hoods are arranged on the side walls of the cabinet body, dust can be prevented from enteringthe cabinet body, and water drops can be prevented from entering the cabinet body from the air inlet hoods at the top of the cabinet body when moisture regaining occurs to the cabinet body. The arranged exhaust hoods can exhaust air flowing from the top out of the cabinet body, circulation of air in the cabinet body is ensured, an arranged heat dissipation mechanism can rapidly blow air into thecabinet body, and when the heat dissipation mechanism carries out exhausting, the air speed in the cabinet body can be changed, so the heat dissipation effect of the cabinet body is improved; therefore, the air flowing speed in the cabinet body can be changed, and the ventilation effect of the cabinet body is better.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to a high-voltage power cabinet with good heat dissipation effect. Background technique [0002] The power cabinet is 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.

AI Technical Summary

Problems solved by technology

[0003] For hot areas and high-voltage power cabinets with many power components inside the power cabinet, although the power cabinet can dissipate heat, the power components inside the power cabinet will generate more heat during long-term use. If the heat dissipation is not timely It is easy to cause the internal temperature of the cabinet to rise, thereby affecting the operation of the power cabinet, and in more serious cases, it will cause an open flame in the power cabinet

However, the heat dissipation process of the existing high-voltage power cabinet is cumbersome, and fans are usually used for heat dissipation, and the heat dissipation effect is not satisfactory. Therefore, a high-voltage power cabinet with good heat dissipation effect is proposed to solve the above problems
