Abstract

The embodiment of the invention discloses a cable accessory and a moisture-proof method thereof. Comprising a cable accessory interface assembly, a plurality of hollow circular tubes and a plurality of hollow prisms, the cable accessory interface assembly comprises an insulating inner surface layer, an insulating middle surface layer and an insulating outer surface layer; the hollow circular pipes are filled with repairing liquid and are transversely arranged in the insulating inner surface layer and the insulating outer surface layer; wherein the repairing liquid is used for carrying out absorption reaction on moisture and moisture entering the cable accessory interface assembly; the roughness of the surface of the hollow circular tube is within a preset range value, so that the migration energy of discharge electrons is reduced; the plurality of hollow prisms are vertically arranged in the insulating middle surface layer; the multiple hollow prisms are filled with repairing liquid. Holes are formed in the surface of the hollow prism and used for preventing the electron discharge process so as to improve the discharge voltage of the cable accessory interface. Through the device, the moisture-proof performance of the cable accessory is improved, so that the probability of cable insulation damage is reduced.

Description

technical field [0001] The present application relates to the technical field of moisture-proofing of cable accessories, and in particular, to a cable accessory and a moisture-proof method thereof. Background technique [0002] Power cable accessories are necessary devices to connect the cable body, connect the cable with the transmission line and the equipment in each substation, and realize the power transmission. [0003] Statistical analysis shows that most of the cable faults are the result of the coupling of multiple factors such as overvoltage and harsh climate environment, among which the majority of faults are caused by moisture and water immersion in cable accessories. [0004] In the prior art, after the moisture or moisture in the environment enters the interior of the cable accessories, partial discharge is prone to occur, so that a large amount of electric charges accumulate at the connection between the cable accessories and the cable, which easily causes the ...
