Graphite layer evenly-brushing device for high-voltage cable

Abstract

The invention discloses a graphite layer evenly-brushing device for a high-voltage cable. The device comprises a rotation drum; the wire entering end of the rotation drum is circumferentially connected with a plurality of supporting rods through bolts; the central axes of the supporting rods are perpendicular to the central axis of the rotation drum; the end portions of the supporting rods are rotationally provided with roller brushes; a curved groove is arranged in the outer wall of the rotation drum; a hollow air pipe is arranged below the rotation cylinder; the air pipe is provided with anair inlet and an air outlet; the air inlet is connected with an air blowing pump through a pipeline; the air outlet is connected with an air extracting pump through a pipeline; a jacking rod is fixedonto the air pipe; the upper end of the jacking rod abuts against two side walls of the curved groove; the jacking rod is provided with a first conductive block and a second conductive block; the first conductive block and the second conductive block are connected with each other through a wire; a hollow traction rod is fixedly connected to the air pipe; a mounting disk is arranged on the top of the traction rod; the disk outer wall and disk inner wall of the mounting disk form a cavity; and a plurality of suction cups which are communicated with the cavity are evenly arranged on the disk inner wall. With the technical schemes of the invention adopted, evenly brushing treatment can be performed on the graphite layer of the high-voltage cable, so that a uniform graphite layer can be obtained.

Description

technical field [0001] The invention belongs to the technical field of high-voltage cable production equipment, and in particular relates to a high-voltage cable graphite layer brushing device. Background technique [0002] High-voltage cables are power cables used to transmit 1KV-1000KV voltage. The composition from the inside to the outside mainly includes: conductors, insulating layers, inner protective layers and outer protective layers. Since the high-voltage cables are subject to DC withstand voltage inspection on the outer protective layer after leaving the factory, delivery acceptance, laying and installation, it is necessary to coat a complete and uniform semi-conductive layer on the surface of the outer protective layer to facilitate inspection of the mechanical seal of the outer protective layer of the cable. Performance and insulation level, and at present, the semiconductor layer is usually obtained by coating liquid graphite on the surface of the outer protecti...
