Description
Technical field
The present invention relates to a kind of electric power overhaul instrument, in particular it relates to a kind of 800KV strain insulator strings disengaging fixture
And its method.During powered exchange of the fixture when exchanging to 800KV strain insulator strings, three cunnings can be walked with walking two
Car, hoist engine coordinate, and can mitigate disengaging weight during the powered exchange of 800KV strain insulator strings, and fixture is not easy to skid off, and drop
Low work difficulty, it is convenient that easily powered monolateral exchange is carried out to insulator chain, improve work efficiency.
Background technology
In the past, extra high voltage network, such as 220kV transmission lines of electricity generally adopt double bundle conductor, and matching is exhausted
Edge also all adopts double serial type formulas.Its powered transmission line of electricity and its insulator string exchanged is for the significant terms in livewire work project
Mesh, needs in the case where safe distance is met, and tightening up insulator chain carries out changing the work such as insulator.
Generally, it is various loads can be made to tighten up such as screw mandrel, cunning for exchanging the various fixtures of transmission line of electricity double insulator string
The instruments such as car group, hydraulic pressure tightener, mechanical tightener and fixture coordinate, and powered monolateral exchange is carried out to insulator chain, work is reduced
Make difficulty, improve work efficiency.For example, a kind of 220KV strain insulators exchange fixture, the fixture include the first fixture and
Second fixture, first fixture and the second fixture are separately positioned on the first gusset piece and second for connecting insulator string
On fishplate bar, on first fixture, be provided with the first coaster hole and bottle supporting frame aperture, be provided with second fixture the 3rd coaster,
Second coaster hole and lead screw hole, are connected with the first coaster on the first coaster hole, second fixture by tightening device with
First fixture 1 connects.During use, after load tightening device is installed, insulator chain is tightened up using tightening device, be allowed to unilateral insulation
After son is lax, manpower departs from and slowly relaxes to ground, meanwhile, keep insulator connection in side intact, to increase safety.Treat
After the completion of side is assigned a new job, fixture is attached to opposite side carries out operation.
However, in recent years, need for electricity amount is greatly increased, will meeting as the 220kV transmission lines of electricity of supertension
Ask, occur in that 500KV, even the 800KV UHV transmission line of 1000kV.The 500KV, the 800KV even spy of 1000kV
Ultra-high-tension power transmission line uses 4-8 split conductors, its transmission line of electricity to use 2-4 insulator strings respectively, and more conventional 220kV is defeated for weight
Electric line is sharply increased.For example, the UHV transmission line of 500KV using 2-4 strings, 28-31 pieces/string, substance 8KG/ pieces it is exhausted
Edge, using 3-4 strings, 78/string, the insulator of substance 28-30KG/ pieces, gross weight is drastically for the UHV transmission line of 800KV
Increase.So, to UHV transmission line power supply reliability, livewire work, powered exchange insulator chain it is also proposed higher
Requirement.
For example, in the past, when the strain insulator string to 220kV transmission lines of electricity is exchanged, because which uses 2-4 strings, 28-
31/string, the insulator of substance 8KG/ pieces, in powered exchange insulator chain, still borrow motor-driven strand to the insulator chain
Mill is easily released so which slowly comes off and hangs down to ground, resets after to be repaired or exchange insulator chain.
However, the UHV transmission line of 800KV using 3-4 string, 78/string, substance 28-30KG/ pieces insulator then
Because the 800KV strain insulator strings weight is bigger, manpower cannot be released, even if borrowing motor-driven grinding mill, which operates inconvenience, takes
Power；When carrying out strain insulator string and being exchanged, it is necessary to using two-three pieces of gusset pieces, by many strings, gross weight up to several tons of insulation
After the secondary connection of substring, released, changed.So as to the connection to the gusset piece proposes requirements at the higher level.In addition, because existing
The restriction of production specification and the requirement of use habit and manufacturing cost, existing powered exchange insulator chain are used, are connected as main
The gusset piece or fixture of component is normalized isosceles triangle or isosceles trapezoid, with hypotenuse, so that strain insulator
String operation is unstable, easily slides out, and causing 800KV strain insulator strings to be exchanged easily cannot be carried out, and safety is even resulted in when serious
The generation of accident.
