[0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion. In daily life, drawer-type low-voltage switchgear is often seen. It is a kind of equipment used in power plants, substations, communities, petrochemical industry, textile and other industrial and mining industries. The cabinet structure can be divided into three types: drawer-type structure, separate structure and fixed structure. The drawer-type low-voltage switchgear has better sealing performance and can better provide power reliability.

[0003] Most of the existing low-voltage switch cabinets are not moisture-proof. Since electrical components are installed inside the low-voltage switch cabinet, short circuits and other conditions are prone to occur when exposed to moisture, causing damage to the electrical components and making the low-voltage switch cabinet unable to operate normally. In addition, since the operating environment of the low-voltage switch cabinet is poor and dusty, dust entering the low-voltage switch cabinet can easily cause line aging and short circuits, resulting in a short service life of the low-voltage switch cabinet, a short number of failures, and a high risk of safety hazards.

[0004] The prior art CN213093734U is a moisture-proof drawer-type low-voltage switch cabinet. It avoids the cabinet from directly contacting the ground by setting a moisture-proof base.
