Description

Technical Field

[0001] The invention belongs to the technical field of power cabinets, and in particular relates to an environmentally friendly power cabinet with good waterproof performance. Background Art

[0002] The power cabinet, also known as the distribution cabinet or electrical control cabinet, is an important device for controlling, protecting and distributing electric energy in the power system. It is widely used in industrial, commercial and residential buildings to ensure the safe, reliable and efficient operation of the power system. Through built-in circuit breakers, fuses, overload protection devices, etc., the power cabinet can automatically cut off the power supply when the circuit is overloaded or short-circuited to protect the circuit and equipment from damage. The power cabinet distributes the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. In the rainy season or humid environment, if the power cabinet is not tightly sealed, external moisture may penetrate into the cabinet, causing circuit leakage, resulting in equipment damage, and even fire and other serious consequences. Water ingress will accelerate metal corrosion and aging of insulating materials, affect the strength and electrical performance of the equipment, and shorten the life of the equipment.

[0003] In the prior art, the internal structure of the power cabinet fails to fully consider the waterproof requirements. For example, the inlet holes and drainage holes are improperly designed, resulting in moisture seeping into the cabinet through the inlet holes. The moisture cannot be removed in time, increasing the risk of equipment getting damp. Summary of the invention
