Abstract

The invention discloses a damp-proof system of a cable branch box. The damp-proof system comprises a main box and an auxiliary box, wherein the main box is used for connecting and transferring cables;a sealing cover is arranged outside exhaust holes of the main box; a dehumidification cavity is formed in the auxiliary box; the lower end of the dehumidification cavity is communicated with the sealing cover through a lower branch pipe, and the upper end of the dehumidification cavity is communicated with the top of the main box through an upper branch pipe; a backflow condensation pipe is arranged outside the upper branch pipe in a sleeved mode, and a fluid capable of flowing is arranged in the backflow condensation pipe; the lower part of the backflow condensation pipe is provided with a drain pipe inclined downwards; a port is formed in the upper end of the drain pipe, wherein the port extends to the interior of the upper branch pipe and the upper end of the port is a top opening; andthe lower end of the drain pipe extends to the outside of the auxiliary box. According to the damp-proof system of the cable branch box, the humidity of the cable branch box can be reduced effectively.

Description

technical field [0001] The invention relates to a cable branch box, in particular to a moisture-proof system for a cable branch box. Background technique [0002] With the rapid development of the modernization construction of the power industry, the transformation of the power grid has started in all directions. When the underground main line cable needs to realize multi-circuit distribution and distribution at a certain distance, it is an economical, convenient and safe way to use the cable branch box as an important supporting equipment for power distribution. The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer cables, mainly for cable branching and cable transfer. [0003] The operating conditions of the cable branch box have requirements on the humidity, specifically: the average daily relative humidity does not exceed 95%, and the average monthly relative humidity does not exceed 90%; once the humidit...
