Description
Technical field
The present invention relates to a kind of electric power overhaul instrument, in particular it relates to a kind of more than 500KV is used for transmission line resistance to
Open insulator chain charged for replacement gold utensil and using method thereof.Described gold utensil is to more than 500KV strain insulator
When string is exchanged, can walk three coasters with walking two, hoist engine coordinates, and can alleviate more than 500KV strain insulator
Disengaging weight when ribbon electricity is exchanged, and gold utensil is not easy to skid off, and reduces work difficulty, convenient to insulator chain
Carry 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 work 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 supertension 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 more than 500KV's is extra-high
Pressure transmission line uses 3-4 string, 78/string, the insulator of substance 28-30KG/ sheet, and gross weight sharply increases.
So, the power supply reliability of UHV transmission line, livewire work, charged exchange insulator chain be it is also proposed
Higher 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 more than 500KV uses 3-4 string, 78/string, substance 28-30KG/
The insulator of sheet is then bigger because of described more than 500KV strain insulator string weight, and manpower cannot get loose, even if borrowing
With motor-driven grinding mill, its operation is inconvenient, laborious；When carrying out strain insulator string and exchanging, it is necessary to use two
-three pieces of gusset pieces, by go here and there more, always weigh several tons insulator chain secondary connect after, get loose, change.
Thus, the connection to described gusset piece proposes requirements at the higher level.It addition, because of the restriction of existing production specification and use
Custom and the requirement of manufacturing cost, existing charged exchange insulator chain with, as the gusset piece of main connecting elements
Or fixture is normalized isosceles triangle or isosceles trapezoid, there is hypotenuse, so that strain insulator string behaviour
Making shakiness, easily slide out, causing more than 500KV strain insulator string to be exchanged cannot easily be carried out, time serious very
To the generation causing security incident.
