Description

A dust-proof and heat-dissipating electrical cabinet

technical field

The utility model belongs to the technical field of power distribution equipment, in particular to a dust-proof and heat-dissipating electrical cabinet.

Background technique

Electrical cabinets, also known as distribution boxes, distribution cabinets, 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 level of equipment should provide protection, monitoring and control of the load. Due to the large number of internal electrical equipment, a large amount of heat will inevitably be generated during operation. Usually, a separate cooling device needs to be installed inside to dissipate heat, while a lot of dust is often accumulated on the outside, and the dust is flying. It may cause current flying string, thus posing a safety hazard. However, there are still various problems in various dust-proof and heat-dissipating electrical cabinets on the market.

For example, a multifunctional high-voltage electrical cabinet disclosed by the authorization announcement number CN207165976U, although the utility model has a novel structure, the electrical cabinet can be radiated by the heat dissipation structure and can also be dust-proof. The cabinet enters the environment for drying, and is also equipped with solar power generation, which can supply power to some equipment of the electrical cabinet through solar energy. At the same time, it is also equipped with an automatic fire extinguishing device and a bird repelling device, which can improve the continuous protection function of the electrical cabinet, but it has not solved the problem. The existing dust-proof and heat-dissipating electrical cabinets have problems that the internal temperature is high and cannot be replaced, the external cold air cannot come in and circulate, and the shell needs to be cleaned manually. For this reason, we propose a dust-proof and heat-dissipating electrical cabinet.
