Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, and more specifically to a high-efficiency moisture-proof large-scale power distribution cabinet. Background Art

[0002] A large distribution cabinet usually contains multiple small distribution cabinets, which are used to distribute power and control electrical equipment to meet the needs of different circuits. Large distribution cabinets are usually equipped with inspection ports to facilitate the inspection, maintenance and replacement of internal equipment.

[0003] When it rains and there is water on the ground, the distribution cabinet is prone to moisture and water ingress. The inspection ports of existing large distribution cabinets are not designed reasonably, which can easily lead to liquid entering through the inspection ports. The poor sealing performance of some inspection ports will also increase the possibility of liquid entry. Once the liquid enters the inspection port, it will only be discovered during regular maintenance. If appropriate measures are not taken in time, excessive liquid accumulation will cause the equipment under the inspection port to be exposed to a humid environment, increasing the risk of equipment damage and posing a safety hazard.

When the seal is not good, the water entering the surrounding frame is introduced into the detection groove through the water guide groove (the water guide groove is low in the middle and high at the end), which can be detected in time by the liquid sensor, so that the maintenance personnel can be notified in time to take corresponding measures to prevent the liquid from entering the inspection port and causing adverse effects.

[0036] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
