AI Technical Summary

Technical Problem

Existing methods for moisture protection in distribution boxes involve frequent switching on heating wires for drying and frequent replacement of desiccants, resulting in high energy consumption and maintenance costs.

Method used

Design a desiccant reduction device. When an abnormal humidity is detected by a humidity sensor, the controller controls the heating wire to heat the desiccant. An external circulation air path is formed through the air inlet and outlet pipes to achieve rapid heating and reduction of the desiccant, restore its moisture absorption capacity, and avoid frequent desiccant replacement and frequent operation of heating equipment.

Benefits of technology

It effectively reduces maintenance costs and energy consumption, ensures the continuity of the desiccant's moisture-proof effect, avoids the energy waste of frequent desiccant and heating equipment replacement, and improves the moisture-proof effect.

Abstract

The utility model relates to a drying agent reduction device for a distribution box. The drying agent reduction device comprises a mounting frame, a reduction bin, a drying agent bin, a humidity sensor, an air inlet pipe and an exhaust pipe, the reduction bin is mounted on the mounting frame, the reduction bin is provided with a heating cavity, and a heating wire is arranged in the heating cavity; a drying window for gas exchange with the distribution box is formed in the side wall of the reduction bin; the drying agent bin is arranged in the reduction bin, a drying agent capable of being heated and reduced is arranged in the drying agent bin, and a plurality of air holes are formed in the drying agent bin; one end of the air inlet pipe communicates with the reduction bin, and the other end communicates with the outside; one end of the exhaust pipe is communicated with the reduction bin, the other end of the exhaust pipe is communicated to the outside, and fans and electric control valves are arranged on the air inlet pipe and the exhaust pipe; the humidity sensor is installed on the installation frame and located in the distribution box. And when the humidity sensor detects that the humidity in the distribution box is abnormally increased, the heating wire, the fan and the electric control valve are opened to heat and restore the drying agent, so that the continuous moisture-proof effect of the drying agent is ensured.
