Abstract
The utility model discloses an insulating plug for the outlet of an outdoor cable protection pipe. The insulating plug comprises an external-insulation seal pipe, and an outdoor cable is arranged in the external-insulation seal pipe. The external-insulation seal pipe is composed of a conical pipe body at the end portion and a diameter-equivalent pipe segment connected and integrated with the conical pipe body, and at least three pipe contracting seams are uniformly arranged in the conical pipe body. A silicone-rubber lining is also arranged in the external-insulation seal pipe, and is provided with pipe contacting seams at positions corresponding to the pipe contracting seams in the conical pipe body. A buckling edge is arranged on the external-insulation seal pipe, and the silicone-rubber lining wraps the inner wall of the buckling edge. The external surface of the diameter-equivalent pipe segment is provided with outside threads, and the inner wall of a diameter-equivalent pipe segment of a sheath pipe which matches the external-insulation seal pipe is provided with inside threads. The insulating plug for the outlet of the outdoor cable protection pipe is simple in structure and convenient to operate, water is effectively prevented from entering the cable protection pipe, distribution accidents are reduced, the normal running of a line is ensured, and the maintenance rate of the distribution cable line is decreased.
Description
Technical field
The utility model relates to the outdoor cable protection tube outlet water-tight device using on a kind of distribution cable circuit; a kind of outdoor cable protection tube outlet insulator seal plug specifically; be mainly used in the shutoff of transformer station and switchgear house turnover cable protection pipe; prevent that the interior water inlet of cable protection pipe and mouth of pipe cable are impaired; improve the cable cycle of operation; reduce distribution accident, guarantee that circuit normally moves.
Background technology
In recent years; along with the quickening of power grid construction; the extensive use of distribution cable circuit; the shutoff situation of cable protection pipe outlet also exposes many problems; the cable insulation bringing thus damages and causes line tripping to happen occasionally; directly affect the safe operation of circuit, cause a hidden trouble to equipment and personal safety.After the construction of traditional cable line,, along with exposing to the sun and rain, there is summer high temperature depression, sink in the effective waterproof clay shutoff of cable protection, and winter low temperature hardens, dry and cracked defect, brings potential safety hazard at aspects such as waterproof, cable are impaired.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of outdoor cable protection tube outlet insulator seal plug is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of outdoor cable protection tube outlet insulator seal plug, comprise external insulation sealed tube, electrical outdoor cable is arranged in external insulation sealed tube, external insulation sealed tube forms by the conical pipe of end with the equal diameter pipeline section that conical pipe connects as one, on conical tube, be at least evenly provided with three draw seams, in insulated enclosure pipe, be also provided with silicon rubber inner covering outside, on silicon rubber inner covering, stitch corresponding position with the draw and be also provided with draw seam, on external insulation sealed tube, be provided with locking edge, silicon rubber inner covering is wrapped on the inwall of locking edge, on equal diameter pipeline section outer surface, be provided with external screw thread, on the equal diameter pipeline section inwall of the outer tube matching with external insulation sealed tube, be provided with internal thread.
Above-mentioned outdoor cable protection tube outlet insulator seal plug, the equal diameter tube section ends of insulated enclosure pipe is provided with positioning and locking annular steps outside, and equal diameter tube section ends and the positioning and locking annular steps of outer tube are interference fit.
Above-mentioned outdoor cable protection tube outlet insulator seal plug, described draw seam is six.
Adopt above-mentioned technical characterictic, the utility model has following advantage: on conical tube, be provided with draw seam, outer tube is packed into after external insulation sealed tube, turn outer tube, draw seam tightens up, receive the object of clamping cables linear sealing, be provided with silicon rubber liner simultaneously in external insulation sealed tube, its sealing effectiveness is ensured more.The utility model is simple in structure, easy to operate, effectively prevents water inlet in cable protection pipe, reduces distribution accident, has guaranteed the normal operation of circuit, has reduced the maintenance rate of distribution cable circuit.
