Abstract
The utility model discloses an insulating plug for the outlet of an outdoor cable protection pipe, characterized by comprising an outer sheath, a silicone rubber inner liner layer and bolts, wherein the edges of both sides of the outer sheath are provided with locking sides, the locking sides are provided with through holes, the inner walls of the outer sheath and the locking sides are respectively provided with the silicone rubber inner liner layer, and the bolts are fixedly arranged inside the through holes. The insulating plug for the outlet of an outdoor cable protection pipe is simple in structure, low in cost and easy in mounting, and can effectively prevent water from entering into the cable protection pipe, thereby reducing power distribution accidents, ensuring the normal operation of the lines, and reducing the maintenance rate of the power distribution cable lines.
Description
Technical field
The utility model relates to the outdoor cable protection tube outlet water-tight device that uses on a kind of distribution cable circuit; a kind of outdoor cable protection tube exports the 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 the distribution accident, guarantee that circuit normally moves.
Background technology
In recent years; quickening along with 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 that brings thus damages and causes line tripping to happen occasionally; directly affect the safe operation of circuit, cause a hidden trouble for equipment and personal safety.After the construction of traditional cable line, along with exposing to the sun and rain, there is the summer high temperature depression in the effective waterproof clay shutoff of cable protection, sinks, and winter low temperature hardens, dry and cracked defective, brings potential safety hazard at aspects such as waterproof, cable are impaired.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, with low cost, install easily, can effectively prevent water inlet in the cable protection pipe, guarantee the outdoor cable protection tube outlet insulator seal plug of the normal operation of circuit.
In order to reach above purpose; the technical scheme that the utility model adopts is: this outdoor cable protection tube outlet insulator seal plug; it is characterized in that: comprise that overcoat, silicon rubber inner covering and bolt consist of; the edge, both sides of overcoat is provided with locking edge; locking edge is provided with through hole; all be provided with the silicon rubber inner covering on the inwall of described overcoat and locking edge, bolt fixedly is located in the through hole.
Described overcoat is made of upper ring cap, spacer shell and lower ring set, and the top of spacer shell is fixed on the bottom of upper ring cap, and the bottom of spacer shell is fixed on the top of lower ring set, and upper ring cap, spacer shell and lower ring set are as a whole.
The cross section of described overcoat, for circular-arc, or semicircle.
The beneficial effects of the utility model are: simple in structure, with low cost, install easily, effectively prevent water inlet in the cable protection pipe, and reduce the distribution accident, guaranteed the normal operation of circuit, reduced the maintenance rate of distribution cable circuit.

Embodiment
Make the utility model with reference to accompanying drawing 1, Fig. 2, Fig. 3.This outdoor cable protection tube outlet insulator seal plug; it is characterized in that: comprise overcoat; silicon rubber inner covering 5 and bolt 6 consist of; the edge, both sides of overcoat is provided with locking edge 4; locking edge 4 is provided with through hole 7; all be provided with silicon rubber inner covering 5 on the inwall of described overcoat and locking edge 4; bolt 6 fixedly is located in the through hole 7; like this, overcoat can be set in the exit of cable protection pipe, the top of silicon rubber inner covering 5 is wrapped on the cable; the bottom is wrapped on the outlet outer wall of protection tube; with bolt 6 fixing getting final product, to prevent water inlet and loosening in the cable protection pipe, play a protective role again; simple in structure, easy to use.
Described overcoat is made of upper ring cap 1, spacer shell 2 and lower ring set 3, and the top of spacer shell 2 is fixed on the bottom of upper ring cap 1, and the bottom of spacer shell 2 is fixed on the top of lower ring set 3, and upper ring cap 1, spacer shell 2 and lower ring set 3 are as a whole.
The cross section of described overcoat, as a whole is circular-arc, is made by the material that can bend, and such as tagger etc., during use, both sides can be curved inwardly, the locking edge 4 of both sides is coincided together after, fixing with bolt 6.
The cross section of described overcoat is semicircle, is made by the hard material that can not bend, and such as cast iron sheet, thick paster, duroplasts etc., the outer end of each semicircle is provided with locking edge, during use, needs two semicircles are buckled togather, and fixes with bolt again.
Size and the cable of described upper ring cap 1 adapt, and size and the protection tube of lower ring set 3 adapt, and the diameter of lower ring set 3 is greater than the diameter of upper ring cap 1.
