Technical Field

The utility model relates to the field of power distribution cabinets, in particular to a basement power distribution cabinet which is convenient for ventilation and moisture-proofing.

Background Art

A distribution cabinet is a device used to distribute, control and protect power systems. It is commonly used in industrial, commercial and residential buildings. It is responsible for transmitting electrical energy from the power source to various electrical equipment while providing necessary electrical protection functions. The main functions of the distribution cabinet include power distribution, overload and short-circuit protection, power metering, electrical control and monitoring of the power system. They ensure the stable and reliable operation of the power system and provide control and management of each circuit.

With the continuous development of social economy, the electrical equipment used by people is increasing, so a large number of distribution cabinets are needed to meet people's daily electricity needs. The distribution cabinets of some communities and office buildings are usually set up in the basement. Because the basement is not exposed to sunlight all year round and the air circulation is poor, the basement is relatively more humid, which can easily cause the electrical appliances inside the distribution cabinet to get damp and age, resulting in damage to the distribution equipment. For this reason, we propose a basement distribution cabinet that is easy to ventilate and moisture-proof to solve the above problems.
