Description
Technical field
A kind of the present invention relates to electric power overhaul devices and methods therefor, in particular it relates to extra-high voltage (1000KV) transmission line of electricity
Whole string strain insulator exchange devices and methods therefor.Described UHV transmission line whole string strain insulator exchange device and
Its method can mitigate disengaging weight during the powered exchange of extra-high voltage strain insulator string, and fixture is not easy to skid off, and reduces work
Difficulty, conveniently carries out easily powered monolateral exchange to insulator chain, improves work efficiency.
Background technology
In the past, extra high voltage network, the such as commonly used double bundle conductor of 220kV transmission line of electricity, matching is exhausted
Edge also all adopts double serial type formulas.Its powered transmission line of electricity and its insulator chain exchanged is for the significant terms in livewire work project
Mesh, needs, in the case of meeting safe distance, to tighten up insulator chain and carry out changing the work such as insulator.
Generally, it is various loads can be made to tighten up 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 cooperation, carry out powered monolateral exchange, reduce work to insulator chain
Make difficulty, improve work efficiency.For example, a kind of 220KV strain insulator exchange fixture, described fixture include the first fixture and
Second fixture, described first fixture and the second fixture are separately positioned on the first gusset piece and second for connecting insulator string
On fishplate bar, described first fixture is provided with the first coaster hole and bottle supporting frame aperture, described second fixture is provided with the 3rd coaster,
Second coaster hole and lead screw hole, described first coaster hole is connected with the first coaster, described second fixture pass through tightening device with
First fixture 1 connects.During use, after load tightening device is installed, tighten up insulator chain using tightening device, be allowed to unilateral insulation
After son is lax, manpower departs from and slowly relaxes to ground, meanwhile, keeps side insulator to connect intact, to increase safety.Treat
After the completion of being assigned a new job in side, fixture is attached to opposite side and carries out operation.
However, in recent years, need for electricity amount greatly increases, and the 220kV transmission line of electricity as supertension will meeting
Ask, occur in that the UHV transmission line of 500KV, 800KV or even 1000kV.The spy of described 500KV, 800KV or even 1000kV
Ultra-high-tension power transmission line uses 4-8 split conductor, and, respectively using 2-4 insulator string, more conventional 220kV is defeated for weight for its transmission line of electricity
Electric line sharply increases.For example, the UHV transmission line of 500KV use 2-4 string, 28-31 piece/string, substance 8KG/ piece exhausted
Edge, the UHV transmission line of 800KV uses 3-4 string, 78/string, the insulator of substance 28-30KG/ piece, the spy of 1000KV
Ultra-high-tension power transmission line uses 3-4 string, 5,60/string, the insulator of the substance piece of KG/ more than 20, and gross weight sharply increases.So, right
The power supply reliability of UHV transmission line, 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 line of electricity is exchanged, because it uses 2-4 string, 28-
31/string, the insulator of substance 8KG/ piece, in powered exchange insulator chain, still borrow motor-driven strand to described insulator chain
Mill easily got loose so that it slowly comes off and hangs down to ground, to be repaired or exchange insulator chain after reset.
As described above, the ultrahigh voltage alternating current transmission lines strain insulator string weight of 1000KV is bigger, manpower cannot get loose,
Even if borrow motor-driven grinding mill, its operation is inconvenient, laborious；Carrying out when strain insulator string is exchanged it is necessary to use two-three pieces
Gusset piece, by many strings, several tons of the insulator chain of always weighing is secondary connect after, got loose, changed.Thus, to described gusset piece
Connection propose requirements at the higher level.In addition, because of the restriction of existing production specification and the requirement of use habit and manufacturing cost, existing band
It is normalized isosceles triangle or isosceles ladder that electricity exchanges insulator chain use, the gusset piece as main connecting elements or fixture
Shape, has hypotenuse, so that strain insulator string operation is unstable, easily slides out, and leads to 1000KV strain insulator string to be exchanged
Cannot easily carry out, when serious, even result in the generation of security incident.
Application No. " 201410359584.1 ", a kind of invention entitled " strain insulator string for super-high voltage transmitting line
The patent of charged for replacement gold utensil and its method " discloses a kind of following technical proposals：
