Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and more specifically, to a combined power distribution cabinet. Background Technology

[0002] Currently, distribution cabinets are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are few circuits; motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] As we all know, distribution cabinets contain various electrical components and are connected by various wires. When the distribution cabinet starts working, the electrical components will generate high temperatures, causing the temperature inside the distribution cabinet to rise. The distribution cabinet is a semi-enclosed structure with limited air circulation, making it difficult for hot air to dissipate. In addition, the continuous operation of the distribution cabinet will cause the electrical components and wires to be in a high-temperature environment for a long time, which will shorten the life of the electrical components and wires and create safety hazards for the distribution cabinet. Summary of the Invention

[0004] Therefore, in order to solve the problem that the lifespan of electrical components and wires is shortened due to prolonged exposure to high temperatures, leading to safety hazards in the distribution cabinet, this invention provides a modular distribution cabinet, the specific technical solution of which is as follows:
