Description

A complete set of cabinet structure with openable top cover

technical field

The invention relates to the technical field of complete cabinet structures, in particular to a complete cabinet structure with an openable top cover.

Background technique

High and low voltage complete sets of equipment include switch cabinets, switchboards, control boxes, switch boxes and other electrical equipment. 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. Power distribution cabinet is a general term for motor control center. The power distribution cabinet is used in situations where the load is relatively scattered and there are few circuits; the motor control center is used in the situations where the load is concentrated and there are many circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This class of equipment shall provide protection, monitoring and control of the load.

Various AC equipment power distribution cabinets have been developed and used for many years. Although they are very mature products, they still require troublesome steps and have certain dangers when installing or maintaining internal equipment. Generally, it is necessary to remove the cover fixed on the top of the cabinet first, and then remove the cover from the top of the cabinet with a height of 2 to 3 meters before completing the installation or removal of the internal equipment. The cover plate of the existing cabinet top is generally integrated with the cabinet, and the cover plate does not have a detachable function, so the entire installation and disassembly process of the equipment inside the cabinet is relatively cumbersome.

The use of high and low voltage complete equipment cabinets will appear in some harsh environments, which have extremely high requirements on equipment performance. Once the equipment is stopped or damaged due to excessive temperature, it will cause economic losses and bring inconvenience to people's lives. The heat dissipation effect in the housing of the high and low voltage complete sets of equipment is poor, and it will take up a lot of installation space. To this end, we have introduced a complete cabinet structure with an openable top cover.
