Abstract

The invention discloses a power distribution box waterproof structure. The waterproof structure comprises a box body, a box door is hinged to the box body, the surfaces of the inner walls of the two sides of the box body are movably connected with a plurality of drying agent storage grooves, a bagged drying agent is arranged in the drying agent storage grooves, an air inlet is formed in the upperend of the box body and is connected with a draught fan through an air pipe, a filtering and drying assembly is further connected between the draught fan and the air pipe, an air outlet is formed in the lower portion of one side wall of the box body, and a height adjusting assembly is further arranged at the lower end of the box body. The drying agent storage grooves are formed in the box body tocontain the bagged drying agent, so moisture contained in air in the box body can be adsorbed at ordinary times, and the phenomenon of short circuit caused by too high air humidity in the box body canbe effectively avoided. The filtering and drying assembly is arranged to make air, sucked in by the draught fan, dried and filtered, the dried air enters the box body, the air in the box body can bereplaced, and when the air humidity in the box body is too high, the air humidity in the box body can be rapidly reduced, so the dehumidification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power devices, in particular to a waterproof structure for a power distribution box. Background technique [0002] The distribution box is divided into power distribution box, lighting distribution box and metering box, and is the final equipment of the power distribution system. The distribution box is a general term for the motor control center. The distribution box is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] The voltage in the distribution box is high. If water enters, it will leak electricity, which will cause danger, and will...
