Abstract
The utility model relates to a 220kV power transmission line quad-bundle jumper wire parallel groove clamp. The parallel groove clamp comprises a clamp main body. A pressing cover is respectively arranged above and under the clamp main body. The pressing covers arranged above and under the clamp main body are fixed on the clamp main body through bolts. The clamp main body and the pressing covers form a rectangle with round corners. Preferably, rectangular projections are arranged on the pressing covers. Rectangular grooves matching rectangular projections are arranged on the clamp main body. The provided parallel groove clamp decreases the horizontal and vertical distances between wires, can shortens the tensile pole tower cross-arm layer spacing and the cross-arm length, shortens the tower head size, saves clamp materials, has a more beautiful and concise appearance than a quad-bundle jumper wire spacing bar used at present, and is convenient for processing and construction.
Description
Technical field
The utility model relates to a kind of for keeping the gold utensil of wire jumper fixed geometry, is specifically related to a kind of 220kV transmission line quadripartion wire jumper parallel groove clamp.
Background technology
Along with the high speed development of Chinese national economy, circuit ability to transmit electricity is required to improve constantly, conductors on quad bundled conventional in 500kV electric pressure circuit also progressively starts to be applied in the transmission line of 220kV electric pressure.In order to suppress the electric field strength on wire jumper surface, for the wire jumper of 500kV and above transmission line, heading spacing value is generally identical with shelves inside conductor, is 400-500mm.For 220kV transmission line quadripartion wire jumper, conventionally to fix with jumper wire spacing rod at present, heading spacing is also 400-500mm, and tower head size is increased.And in fact, less, identical with the 500kV circuit heading spacing of wire jumper surface electric field strength of 220kV transmission line, the horizontal and vertical spacing of division wire jumper can be compressed to very little.In order to reduce the spacing of 220kV transmission line quadripartion wire jumper sub-conductor, shorten cross-arm length and the cross-arm interfloor distance of strain rod tower, reduce project cost, thus be necessary to develop new 220kV quadripartion wire jumper parallel groove clamp, to replace quadripartion jumper wire spacing rod.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of 220kV transmission line quadripartion wire jumper parallel groove clamp is provided.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of 220kV transmission line quadripartion wire jumper parallel groove clamp, comprise wire clamp main body, the above and below of described wire clamp main body is provided with gland, the gland of described wire clamp main body above and below is bolted in wire clamp main body by one, described wire clamp main body and a rectangle with fillet of described gland composition.
Further, described gland is provided with rectangular preiection, in described wire clamp main body, is provided with the rectangular recess matching with described rectangular preiection.
Further, between described bolt and described gland, be provided with pad and spring shim.
The beneficial effects of the utility model are: the 220kV transmission line quadripartion wire jumper parallel groove clamp that the utility model provides, reduce the horizontal and vertical distance between wire, can shorten strain rod tower cross-arm interlamellar spacing and cross-arm length, dwindle tower head size, and save the material of wire clamp, profile is more attractive in appearance, succinct than the quadripartion jumper wire spacing rod using at present, processing and easy construction.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
220kV transmission line quadripartion wire jumper parallel groove clamp of the present utility model is as shown in Fig. 1-Fig. 6, comprise wire clamp main body 2, the above and below of wire clamp main body 2 is provided with gland 1, two glands 2 of wire clamp main body 2 above and belows are fixed in wire clamp main body 2 by a bolt 3, and wire clamp main body 2 and gland 1 form a rectangle with fillet.As shown in Figure 6, gland 1 is provided with rectangular preiection 8, is provided with the rectangular recess 7 matching with rectangular preiection 8 in wire clamp main body 2, is provided with pad 4 and spring shim 5 between bolt 3 and gland 1.
When use, upper and lower two glands 1 are fixing by concaveconvex structure and a bolt 3 with wire clamp main body 2.When mounted, first not inserting bolt 3, after sandwiching wire jumper, only fix with gland 1 and the concaveconvex structure of wire clamp main body 2, after treating that four wire jumpers all install, then inserting bolt 3, put into successively pad 4, spring shim 5, finally overlap upper cap nut 6, be completely fixed.
The 220kV transmission line quadripartion wire jumper parallel groove clamp that the utility model provides, reduce the horizontal and vertical distance between wire, its heading spacing is to commonly use at present 1/5th of jumper wire spacing rod, can shorten strain rod tower cross-arm interlamellar spacing and cross-arm length, dwindle tower head size, and saved the material of wire clamp, profile is more attractive in appearance, succinct than the quadripartion jumper wire spacing rod using at present, processing and easy construction.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection range of the utility model claim.
