Multi-mode power distribution cabinet

Abstract

The invention discloses a multi-mode power distribution cabinet. The multi-mode power distribution cabinet comprises a cabinet body, wherein a top cover is fixedly connected to the top end of the cabinet body; a circle of strip-shaped ventilation holes are formed in the side wall of the top cover, and fans are fixedly arranged on the two sides of the inner wall of the top end of the top cover respectively; two rows of insulation heat dissipation plates are hung above the inner part of the cabinet body through an electric telescopic rod and a corresponding connecting arm; electric heating wiresare fixed on the heat dissipation plates; a fourth temperature sensor and a third temperature sensor are further installed at the lower end of the interior of the cabinet body separately; a first temperature controller is further arranged in the cabinet body; a row of strip-shaped heat dissipation holes are formed in the side walls of the two ends of the cabinet body; the inner wall of each strip-shaped heat dissipation hole is rotationally connected with an air guide plate through a rotating shaft; and the air guide plate can adjust the opening degree of the strip-shaped heat dissipation holes. According to the multi-mode power distribution cabinet, a proper temperature can be kept by utilizing the heating wires when the temperature of the cabinet body is relatively low; meanwhile, different heat dissipation modes are adjusted according to different temperature values in the cabinet body, so that energy waste is avoided; and in addition, a heating assembly can be freely folded and put according to needs, so that the cabinet is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a multi-mode power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and 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] For some high-voltage power distribution cabinets used for power distribut...

AI Technical Summary

Problems solved by technology

[0003] For some high-voltage power distribution cabinets used for power distribution and control of high-end electromechanical equipment, especially the internal electrical components are more precise, so these precision electrical components have higher requirements on temperature conditions, the temperature fluctuates from high to low, or is too high or too high. Low will affect the precision of electrical components, resulting in inaccuracy of control parameters, and although the existing ordinary high-voltage power distribution cabinets have simple heat dissipation and heating components, it is often difficult to meet the relatively stable temperature conditions in the cabinet. The heating element is fixed installation, which not only poses a safety hazard, but also hinders the cooling effect of the fan
