Abstract

The invention discloses a magnetic type self-repairing cable protection pipe, and belongs to the field of cables. The scheme that an expansion repairing ball is extruded by impact force to trigger a repairing device of the expansion repairing ball is adopted to repair a damaged part at the outer end of a wrapping layer, so that the damage of the outer end of the wrapping layer is avoided. An arc-shaped top plate and a supporting plate buffer the impact force of the outer end of the wrapping layer, so damage caused by extrusion to the embedded cable is effectively reduced; when the expansion repair ball is triggered by extrusion, repair glue is extruded out of the hollow expansion ball and covers the damaged position of the wrapping layer; and when the outer end of a pre-buried cable is damaged due to excessive impact force, an electromagnetic field is generated, the electromagnetic field adsorbs the rubber magnetic particles in the fixing pipe, the insulating glue and the rubber magnetic particles are adsorbed to the outer side of the pre-buried cable through the release holes, and leakage current is not likely to be conducted while the rubber magnetic particles and the electromagnetic field are adsorbed to each other, so the safety after repair is improved.

Description

technical field [0001] The invention relates to the field of cables, more specifically, to a magnetic self-repairing cable protection tube. Background technique [0002] Cable is a general term for optical cables, cables and other items. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, and power transmission. It is a common and indispensable thing in daily life. Because cables are charged, So installation requires special care. [0003] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulated covering layer, the cable has the characteristics of internal electrification and external insulation. [0004] The wire and cable products used in the power system power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oi...
