Description

Technical Field

[0001] The utility model belongs to the technical field of electrical cabinets, and in particular relates to a high- and low-voltage electrical mechanism with low-voltage heat dissipation protection. Background Art

[0002] Electrical cabinets are made of steel and are used to control, protect and distribute electricity. The materials used are generally divided into hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel plates, cold-rolled steel plates are softer and more suitable for the production of electrical cabinets. Electrical cabinets are mainly composed of switches, instruments, protection components, etc., which can control and protect the power system. Electrical cabinets are widely used and are mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring and transportation industry, etc. In the industrial field, electrical cabinets are mainly used to control motors, transmit signals and protect electrical equipment; in the construction field, electrical cabinets are usually used to control power distribution, lighting and HVAC equipment; in the transportation field, electrical cabinets are widely used in transportation facilities such as railways, subways, and highways to control signal lights, access control, power stations, vehicle detection and other equipment.

[0003] The main reasons for heat dissipation defects in high and low voltage electrical mechanisms are as follows:

[0004] Inadequate heat dissipation design: High and low voltage electrical mechanisms generate a lot of heat during operation. If the heat dissipation design is unreasonable or insufficient, the heat cannot be effectively dissipated, resulting in heat dissipation defects. For example, insufficient heat dissipation surface area, unreasonable number and position design of heat dissipation holes, etc. will affect the heat dissipation effect.

[0005] Poor ventilation: High and low voltage electrical mechanisms usually need to operate in a closed environment. If the ventilation is poor and the air circulation is not smooth, the heat cannot be effectively discharged, thus causing heat dissipation problems.

[0006] Heat dissipation blind spots: The existing high and low voltage electrical mechanisms have complex shapes and there are blind spots in the airflow, making it difficult to achieve efficient heat exchange and easily causing heat accumulation. Utility Model Content
