Dehumidification and anti-condensation distribution box

Abstract

The invention discloses a dehumidification and anti-condensation distribution box, comprising a box body, wherein a first air channel and a second air channel are arranged on the box body, a dehumidification device is respectively arranged in the first air channel and the second air channel, the dehumidification device comprises a cylindrical shell, a plurality of groups of first through holes aligned at both ends and a plurality of second through holes at one side are formed in the cylindrical shell, the first through holes and the second through holes are arranged at intervals, a rotating block is rotatably arranged in the cylindrical shell, a plurality of accommodating cavities of which both ends are communicated are arranged in the rotating block, filter screens are arranged at both ends of each accommodating cavity, silica-gel desiccants are arranged in the plurality of accommodating cavities at intervals, electric heating wires are arranged in the accommodating cavities with thesilica-gel desiccants, the rotating block is connected with an output shaft of a motor, a first air inlet fan is arranged on the first air channel, a second air inlet fan is arranged on the second airchannel, and the motor, the electric heating wires, the first air inlet fan and the second air inlet fan are all connected with a control device. The distribution box can effectively prevent the occurrence of condensation on the surfaces of internal components of the distribution box, and is low in use cost.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to a dehumidification and anti-condensation distribution box. Background technique [0002] Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box; On or off the circuit; when there is a fault or abnormal operation, the circuit is cut off or the alarm is cut off with the help of the protective device; various parameters in the operation can be displayed by means of the measuring instrument, and some electrical parameters can also be adjusted to prompt or send out the deviation from the normal working state. Signal. The distribution box can reasonably distribute electric energy, facilitate the opening and closing operation of the circuit, has a high level of safety protection, and can intuitively d...

Problems solved by technology

[0003] The distribution box needs to be cooled and dehumidified when it is in use. In the prior art, desiccant is used to absorb water vapor to prevent condensation in the distribution box. However, this method consumes a large amount of desiccant, and the desiccant needs to be replaced in a timely manner. high cost
