Description

Power distribution cabinet

Technical Field

The utility model relates to a power distribution cabinet.

Background

The distribution cabinet (case) is a final-stage device of a distribution system and is divided into a power distribution cabinet (case), a lighting distribution cabinet (case) and a metering cabinet (case). The power distribution cabinet is a general name of a motor control center. The power distribution cabinet is used in the occasions with dispersed loads and less loops, and the motor control center is used in the occasions with concentrated loads and more loops. They distribute the power of a certain circuit of the upper-level distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control of the load.

The indoor power distribution cabinet mainly considers the heat dissipation problem in the design process, for example, a common machine room power distribution cabinet is used, cold air is mainly sent into by a fan at the bottom in the heat dissipation process, hot air after heat exchange is discharged through a heat dissipation groove on the surface of a cabinet body, the heat dissipation of the interior of the cabinet body is realized, however, because more electric elements are arranged in the cabinet body, blocking can be generated among the electric elements, the internal integral temperature of the cabinet body can be normally maintained, and the heat dissipation effect of the partial shielded electric elements is relatively poor.

Based on the problems, the power distribution cabinet capable of achieving uniform distribution of cold air and increasing the heat dissipation effect is designed.
