Abstract
The utility model is a power cable and overhead line connecting device and aims to provide a power cable and overhead line connecting device which is reliable in connection, good in safety, neat and beautiful in wiring and convenient in phase adjustment. The power cable and overhead line connecting device comprises a cross arm embracing a tower, wherein three outdoor post insulators which are linearly arranged at equal intervals are fixed on the cross arm. The power cable and overhead line connecting device is characterized in that three upright wiring copper bars are respectively fixed on the front end faces of the outdoor post insulators, the wiring copper bar in the middle of the end connected with a power cable is shorter, and the other two wiring copper bars at both sides are longer, upper wiring holes are respectively opened on the upper ends of the wiring copper bars and the upper wiring holes are used for fixedly connecting an overhead line, lower wiring holes are respectively opened on the lower ends of the wiring copper bars, and the lower wiring holes are roughly positioned on the arc line of a same radius and are used for fixedly connecting a power cable. The power cable and overhead line connecting device is especially suitable for power cable replacement at the connection of an overhead line and a power cable or live working environments with a load replacing fuse, a column switch or the like.
Description
Technical field
The utility model relates to the jockey that is used for supply line in the electric power system, more specifically to the jockey of a kind of cable and overhead wire.
Background technology
Now to be connected outward appearance unbecoming, quite in disorder for a large amount of outdoor high-voltage cables and overhead wire.The suspension earth connection is inconvenient, long construction period, run into cable and overhead wire phase place when inconsistent adjustment difficulty large, waste time and energy, without impetus, cause easily cable fault when cable joint is connected with overhead wire, there is potential safety hazard, the safety of serious threat electrical production.
The utility model content
The purpose of this utility model provides that a kind of connection is reliable, fail safe is good, wiring neat appearance, phase place is easy to adjust, and particularly suitable has cable transposing or test and be installed in on-load a kind of cable of the live line working environment (the 3rd class live line working) when changing drop type, on-load and changing on-pole switch etc. and the jockey of overhead wire.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: it includes the cross-arm of embracing shaft tower, be fixed with three outdoor post insulators that the word order spacing is identical at cross-arm, it is characterized in that the front end face of post insulator is fixed with 3 upright copper busbars out of doors, described 3 copper busbars are short for be connected the middle copper busbar of an end with cable, two copper busbars on both sides are long, be shaped with wiring hole in the upper end of copper busbar, upper wiring hole is fixedly connected with for overhead wire, the lower end is shaped with lower wiring hole, roughly on the circular arc line with Radius, lower wiring hole power supply cable is fixedly connected with described 3 lower wiring holes.
Described copper busbar is vertical zigzag.
Described upper wiring hole respectively has up and down parallel two groups, is used for the fine setting of distance when overhead wire connects.
Described lower wiring hole respectively has up and down parallel two groups, is used for the fine setting of distance when cable connects.
Below the bending part of each copper busbar front end face, be connected with for the Q-RING that articulates earth connection.
According to the cable of such scheme manufacturing and the jockey of overhead wire, owing to used fixing copper busbar, when cable is connected with overhead wire, after the transition and length adjustment by fixing copper busbar, so that when connecting, more can exert all one's strength between them, connect more reliable, convenient, simultaneously because three copper busbars are short in the middle of the terminals with cable adopt, the structure of two length of sides, can satisfy under normal conditions three situations that cable adapter length is identical, so that each the phase line degree of tightness after connecting is consistent, can not bend, the unnatural situation such as tension, and when occur the wiring phase place not to the time, can arbitrarily change connection to three wiring, the length difference problem can not occur, be convenient to commutation, use very convenient and safety.This structure is specially adapted to the live line working environment at the cable transposing of overhead wire and cable junction or on-load replacing fuse, on-pole switch etc.
