Description

A kind of UHV transmission line bunch of insulator charged for replacement method and gold utensil thereof
Technical field
The present invention relates to electric power overhaul field, in particular it relates to a kind of UHV transmission line bunch of insulator Charged for replacement method and gold utensil thereof.Described method when extra-high voltage strain insulator string is exchanged, can with walk Two walk three coasters, hoist engine cooperation, can alleviate disengaging weight when extra-high voltage strain insulator string is charged to be exchanged, And gold utensil is not easy to skid off, reduce work difficulty, conveniently insulator chain is carried out the most charged exchange.
Background technology
In the past, extra high voltage network, the commonly used double bundle conductor of such as 220kV transmission line of electricity, therewith The insulator joined the most all uses double serial type formula.Its charged exchange transmission line of electricity and insulator string thereof are livewire work item Big event in mesh, needs in the case of meeting safe distance, tightens up insulator chain and be replaced insulator Deng work.
Generally, for various load being made to tighten up such as silk for exchanging the various fixtures of the double insulator string of transmission line of electricity The instruments such as bar, tackle pulley, hydraulic pressure tightener, machinery tightener coordinate with fixture, carry out charged to insulator chain Monolateral exchange, reduces work difficulty, improves operating efficiency.Such as, a kind of 220KV strain insulator is exchanged and is used Fixture, described fixture includes that the first fixture and the second fixture, described first fixture and the second fixture are separately positioned on For the first gusset piece and second gusset piece of connecting insulator string, described first fixture is provided with first sliding Car hole and bottle supporting frame aperture, described second fixture is provided with the 3rd coaster, the second coaster hole and lead screw hole, described Connecting on first coaster hole and have the first coaster, described second fixture is connected by tightening device and the first fixture 1. During use, after load tightening device is installed, utilize tightening device to tighten up insulator chain, be allowed to unilateral insulator pine After relaxation, manpower departs from and slowly relaxes to ground, meanwhile, keeps side insulator to connect intact, to increase peace Quan Xing.After being assigned a new job in side, fixture installation is carried out operation to opposite side.
But, in recent years, need for electricity amount is greatly increased, as the 220kV transmission line of electricity of super-pressure with cannot Meet requirement, occur in that 500KV, the 800KV even UHV transmission line of 1000kV.Described 500KV, The UHV transmission line of 800KV even 1000kV uses 4-8 split conductor, and its transmission line of electricity uses respectively 2-4 insulator string, the more conventional 220kV transmission line of electricity of weight sharply increases.Such as, the extra-high voltage of 500KV Transmission line of electricity uses 2-4 string, 28-31 sheet/string, the insulator of substance 8KG/ sheet, and the extra-high voltage of extra-high voltage is defeated Electric line uses 3-4 string, 78/string, the insulator of substance 28-30KG/ sheet, and gross weight sharply increases.This Sample, it is also proposed more the power supply reliability of UHV transmission line, livewire work, charged exchange insulator chain High requirement.
Such as, in the past, when the strain insulator string of 220kV transmission line of electricity is exchanged, because it uses 2-4 string, 28-31 sheet/string, the insulator of substance 8KG/ sheet, when charged exchange insulator chain, still can be right Described insulator chain is used motor-driven grinding mill and is easily got loose so that it slowly comes off and hangs down to ground, to be repaired Again or reset after exchanging insulator chain.
But, the UHV transmission line of extra-high voltage uses 3-4 string, 78/string, substance 28-30KG/ sheet Insulator is then bigger because of described extra-high voltage strain insulator string weight, and manpower cannot get loose, even if using motor-driven strand Mill, its operation is inconvenient, laborious;When carrying out strain insulator string and exchanging, it is necessary to use two-three pieces of connection Fishplate bar, by go here and there more, always weigh several tons insulator chain secondary connect after, get loose, change.Thus, right The connection of described gusset piece proposes requirements at the higher level.It addition, because of the restriction of existing production specification and use habit and system Cause this requirement, existing charged exchange insulator chain with, as gusset piece or the fixture of main connecting elements be Normalized isosceles triangle or isosceles trapezoid, have hypotenuse, so that strain insulator string operation is unstable, Easily sliding out, causing extra-high voltage strain insulator string to be exchanged cannot easily be carried out, and even results in safe thing time serious Therefore generation.
