Description
Technical field
The present invention relates to a kind of and hook lines to replace tool, and simultaneously hook wire clamp is semi-automatic for especially a kind of overhead transmission line jumper wire
Replacement tool.
Background technology
Aerial high-voltage power transmission line is the important component of power grid, and 220kV transmission lines of electricity are generally using double divisions at present
Conducting wire, the electrical connection of strain rod tower generally use double jump line form, and double jump line is taken and hook wire clamp fixes two wire jumpers
It prevents from mutually whipping or significantly swinging, while also some 110kV line jumpers is that conducting wire surplus material passes through simultaneously hook
What wire clamp and connecing used.But with the influence for being subjected to wind in circuit operational process and wave, rain, aoxidize etc. natural environments,
It often will appear and hook cable clip bolt loosen or the defects of oxidation serious even rupture failure, so as to cause generating heat, whipping, damaging
Wound, the serious major accident for resulting even in wire jumper fracture.
By taking 220kV circuits as an example（110kV circuit distances are more narrow）：Since strain rod tower cross-arm spacing is generally at 3 meters
It left and right, and wire jumper arc sag is generally at 2.2 meters or so is deducted if this results in personnel and be directly entered wherein to carry out equipotential live line work
Human body occupied space cannot be satisfied 2.1 meters with the combinational gap of electrification wire jumper and cross arm of tower, or be examined on wire jumper
It cannot be satisfied with the ground potentials body such as cross arm of tower 1.8 meters of safe distance requirement when repairing operation, therefore for wire jumper and hook line
The replacement operation of folder is generally by the way of interruption maintenance.So it is unfavorable for the stabilization of power grids, two form huge confession
Electric loss.
