Abstract

The invention discloses a device and a method for installing a cable intermediate joint with a moisture-proof structure. The device comprises a core wire stripping device, a polishing device, a silicagel sealing ring and a cable cold-shrinking intermediate joint. The core wire stripping device is used for respectively processing two sections of cable joints to be processed into a pencil head shape. The grinding and polishing device is used for polishing the cable pencil heads of the stripped two sections of the cable; the silica gel sealing ring is used for sleeving the polished cable pencilhead; the cable cold shrinkage intermediate joint is used for installing two sections of cables sleeved with silicone sealing ring and completing sealing connection of the two sections of cables afterglue pouring and cold shrinkage. The device is used to implement the method. The invention solves the technical problem of the safety hidden danger caused by the poor sealing effect of the current distribution network cable intermediate joint.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a device and method for installing a cable intermediate joint with a moisture-proof structure. Background technique [0002] At present, during the connection construction of the power cable joints, the two sections of the cables all use pre-cooled intermediate joints. During the operation of the cable, the moisture will form water droplets between the electrical insulation and the insulation of the intermediate joint prefabricated part. When the water droplets accumulate to a certain amount, water trees will be formed. Under the action of an electric field, the cable will undergo water tree aging, which will eventually lead to breakdown of the insulation. This kind of harm is hidden, not easy to find, and usually not taken seriously by people. This hazard will greatly reduce the service life and safety of cables, and will bring huge economic losses and negative social impacts c...
