Sealed moisture-proof electrical power distribution box

Abstract

The invention discloses a sealed moisture-proof electrical power distribution box and relates to the technical field of power distribution boxes. The sealed moisture-proof electrical power distribution box comprises an outer box body and an outer box cover. An inner box body is fixed to one inner side of the outer box body; an air inlet hole and an air outlet hole are formed in the opposite innerwalls of the inner box body respectively; a first U-shaped clamping slot is fixedly formed in one side face of the inner box body; a second U-shaped clamping slot is fixedly formed in one inner wall of the inner box body; a second moisture absorbing plate is matched with the inner wall of the second U-shaped clamping slot; the inner wall of the first U-shaped clamping slot is matched with an air intake and dehumidification assembly; the air intake and dehumidification assembly includes a clamping block, ventilating adjustment plates and a push block. By designing the outer box body, the outerbox cover, the inner box body, an inner box cover, the air intake and dehumidification assembly, a first exhaust fan, a rectangular box and a second exhaust fan, a box body is sealed and also dividedinto two spaces for separate dehumidification, and the whole box is small in size and solves the problems that existing power distribution boxes with dehumidification functions are generally large insize, mostly conduct open dehumidification and cannot meet requirements of an underground environment.

Description

technical field [0001] The invention belongs to the technical field of distribution boxes, in particular to a sealed and moisture-proof electrical distribution box. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Monitor and control. When the power distribution cabinet is used in an underground space such as an underground parking lot, since the underground space usually has humid air, the power distribution cabinet needs to have a corresponding moisture-proof function. [0003] If the outdoor power distribution cabinet operates in a humid environment, it will bring hidden dangers to its safety. When the temperature is above 30°C and the relative humidity of the air is above 80%, it will cause condensation, which will cause corrosion of the terminals of power equipment. , Reduce the insulation performa...
