Abstract
The utility model discloses a clamping tool used for electriferous replacement of a first insulator of a power transmission line tension single chain at a wire side. The clamping tool includes a transitional connecting plate; the transitional connecting plate is provided with two symmetric extended fittings; each extended fitting is connected with one end of a screw rod; and the other ends of the screw rods are connected with an insulator end clamping plate. Compared with the prior art, the clamping tool of the utility model has the advantages of simple structure, light weight, ingenious design, safety and reliability. With the clamping tool adopted, electriferous replacement of a first insulator of a 110-to-220kV power transmission line tension single chain at a wire side can be realized, and therefore, problems such as difficulties in power outage, long operation time and high labor intensity can be solved, and great economic benefits can be brought about, and the clamping tool is of high practicability, and technical blank in electriferous operation can be filled.
Description
Technical field
The utility model relates to a kind of charged for replacement power line tension list string side of wire was first insulator jig, belongs to electric power apparatus examination technical field.
Background technology
At present, known a lot of 110kV of transformer station, 220kV bus-bar insulator all adopts the connected mode of single string, due to the nonlinear Distribution of insulator, spread voltage on every a slice insulator and pollution level are all different, according to the regularity of distribution of the working voltage of insulator, high by cross-arm side first insulator and side of wire was first insulator other insulator of born voltage ratio that is in operation, the spread voltage particularly bearing by side of wire was first insulator is the highest, therefore be in operation the most aging, cause the dielectric strength of insulator to reduce, finally become low value or zero resistance insulator, jeopardize the safe operation of electrical network.After insulator generation problem, just must overhaul it, all the time owing to there is no effectively separately side of wire was first insulator to be carried out method and the jig of live-line replacing, so all take interruption maintenance at every turn, the mode that whole string is changed, one-stop operation is ordered till end-of-job power transformation operation personnel operating equipment resumes operation from scheduling, at least need 6 hours, so will certainly increase its labour intensity and interruption duration, cause a large amount of energy losses, increase the operating risk that a lot of operations bring, so existing replacing method is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practical, reliability is safe, simple to operate, can carry out monolithic charged for replacement to 110-220kV power line tension list string side of wire was first insulator, there is lower cost of manufacture, lightly facilitate, can save the more activity duration, alleviate the jig of a kind of charged for replacement power line tension list string side of wire was first insulator of operating personnel's labour intensity, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: the jig of charged for replacement power line tension list string side of wire was first insulator, comprise transition connecting plate, in transition connecting plate, be provided with two symmetrical prolongation gold utensils, extend gold utensil and be connected with one end of screw mandrel, the other end of screw mandrel is connected with insulator end clamp.
In transition connecting plate, be provided with connecting hole, transition connecting plate is connected with prolongation gold utensil by connecting hole.
Transition connecting plate is joined by connecting hole and drawtongs.
Owing to having adopted technique scheme, when replacing, insulator end clamp is arranged on second insulator of side of wire was, the drawtongs of transition connecting plate is stuck on wire, tighten up insulator by leading screw, make insulator lax, insulator is changed; Compared with prior art, the utility model not only has simple in structure, the advantage that quality is light, and design ingenious, safe and reliable, can carry out monolithic charged for replacement to 110-220kV power line tension list string side of wire was first insulator and solved the problems such as interruption duration difficulty, the activity duration is long, labour intensity is large, there is larger economic benefit and practicality, solve the problem in actual production work, also filled up a blank of live line working.
