The invention relates to the technical field of power distribution devices, and discloses a power distribution cabinet with an automatic protection mechanism suitable for a wet zone. The power distribution cabinet comprises a shell, air holes are formed in the side surface of the shell, heat dissipation holes are formed in the bottom of the shell, a pressing plate is slidably connected to the lower part of the interior of the shell, and a supporting rod is hinged to the bottom of the pressing plate. According to the power distribution cabinet with the automatic protection mechanism suitable for the wet zone, through cooperative use of sponge and a push rod, when the humidity of the surrounding environment of the power distribution cabinet is too high, the mass of the sponge is increased after the sponge absorbs water, so that a mounting plate drives the push rod to move downwards, the through state of air holes is closed, and the effect of isolating moisture is achieved; and through cooperative use of an ejection mechanism and a baffle plate, when the internal temperature of the power distribution cabinet is too high, the baffle plate can be automatically opened, and heat dissipation holes are used for heat dissipation, so that the influence of too high working temperature on equipment operation is avoided, the maintenance cost is reduced, the loss caused by equipment damage is also avoided, and the application range of the power distribution cabinet is greatly expanded.
Description
technical field [0001] The invention relates to the technical field of power distribution devices, in particular to a power distribution cabinet with an automatic protection mechanism suitable for wet areas. Background technique [0002] The function of the power distribution device is to receive and distribute electric energy during normal operation, and to quickly remove the faulty part and restore normal operation through automatic or manual operation when a fault occurs. It can be said that the power distribution device is an important device to realize the function of electrical main wiring. The power distribution device is an important part of the power plant and the substation, and it is the concrete realization of the electrical main wiring of the power plant and the substation. Common power distribution cabinets have complex and precise electrical systems. Because water and humid environments have a great impact on the electrical system, but because heat dissipatio...
