Abstract

The utility model relates to a 220kV power transmission line four-split tightening type jumper suspension clamp. The 220kV power transmission line four-split tightening type jumper suspension clamp includes an inverted-T-shaped clamp hanging plate and two clamp bases arranged at two sides of the clamp hanging plate; a weight is arranged below the clamp hanging plate; the upper side and the lower side of each clamp base are respectively provided with a pressing cover; the clamp bases are provided with grooves; bolt holes are formed in the grooves; and bolts pass through the bolt holes in the grooves, so that the clamp bases can be fixedly connected with the clamp hanging plate. With the 220kV power transmission line four-split tightening type jumper suspension clamp adopted, horizontal and vertical distances between sub-conductors of a jumper can be decreased, and the interlayer spacing and length of cross arms of a tension tower can be shortened, and the materials of the clamp can be saved. The 220kV power transmission line four-split tightening type jumper suspension clamp is advantageous in more beautiful and concise appearance, and convenient processing and construction.

Description

220kV transmission line quadripartion shrunk type jumper suspension wire clamp
Technical field
The utility model relates to a kind of for the fixing gold utensil of wire jumper of jumper suspension string end, is specifically related to a kind of 220kV transmission line quadripartion shrunk type jumper suspension wire clamp.
Background technology
Along with the high speed development of Chinese national economy, circuit ability to transmit electricity is required to improve constantly, in 500kV electric pressure circuit, conventional conductors on quad bundled also progressively starts to be applied in the transmission line of 220kV electric pressure.The wire jumper of common 500kV and above transmission line, in order to suppress the electric field strength on wire jumper surface, heading spacing value is generally identical with shelves inside conductor, is 400-500mm.For 220kV transmission line quadripartion wire jumper, adopt at present the jumper suspension wire clamp of heading spacing 400-500mm, thereby cause tower head oversize.And in fact, the wire jumper of 220kV transmission line surface electric field strength is less, 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 jumper suspension wire clamp, shorten cross-arm length and the cross-arm interfloor distance of strain rod tower, reduce project cost, therefore be necessary to develop new 220kV quadripartion jumper suspension wire clamp.
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 shrunk type jumper suspension wire 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 shrunk type jumper suspension wire clamp, the wire clamp link plate and two wire clamp bases that are arranged at wire clamp link plate both sides that comprise inverted T-shaped, the below of described wire clamp link plate is linked with heavy punch piece, and described in each, the both sides up and down of wire clamp base are provided with gland.
Further, described gland and described wire clamp base are all symmetricly set in the both sides of described wire clamp link plate.
Further, described wire clamp base is bolted on described wire clamp link plate.
Further, between described bolt and described wire clamp base, be provided with pad and spring shim.
Further, on described wire clamp base, be provided with groove, be provided with bolt hole in groove, wire clamp base is fixedly connected with described wire clamp link plate by the bolt hole in groove by bolt.
Further, described heavy punch piece hang on the below of described wire clamp link plate by bolt.
The beneficial effects of the utility model are: the 220kV transmission line quadripartion shrunk type jumper suspension wire clamp that the utility model provides, reduced the horizontal and vertical distance between wire jumper sub-conductor, can shorten strain rod tower cross-arm interlamellar spacing and cross-arm length, and saved the material of wire clamp, profile is more attractive in appearance, succinct, processing and easy construction.

In figure, 1-gland, 2-wire clamp base, 3-wire clamp link plate, 4-bolt, 5-heavy punch piece, 6-pad, 7-spring shim, 8-nut.
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 shrunk type jumper suspension wire clamp of the present utility model as depicted in figs. 1 and 2, the wire clamp link plate 3 and two wire clamp bases 2 that are arranged at wire clamp link plate 3 both sides that comprise inverted T-shaped, the below of wire clamp link plate 3 is linked with heavy punch piece 5, heavy punch piece can hang on by bolt the below of wire clamp link plate 3, the both sides up and down of each wire clamp base 2 are provided with gland 1, gland 1 and wire clamp base 2 are all symmetricly set in the both sides of wire clamp link plate 3, on wire clamp base 2, be provided with groove, in groove, be provided with bolt hole, wire clamp base 2 is fixedly connected with wire clamp link plate 3 by the bolt hole in groove by bolt 4, between bolt 4 and wire clamp base 2, be provided with pad 6 and spring shim 7.
During use, both sides gland 1 and base 2 are clamped respectively to four wire jumpers on both sides, then be placed in respectively the both sides of wire clamp link plate 3, then inserting bolt 4, bolt 4 is horizontally, puts into successively pad 6, spring shim 7, finally overlaps upper cap nut 8, and it is whole fixing.Then heavy punch piece 5 is hung on to wire clamp link plate below, and available 3 bolts are fixed.
The 220kV transmission line quadripartion shrunk type jumper suspension wire clamp that the utility model provides, reduced the horizontal and vertical distance between wire jumper sub-conductor, its heading spacing is 1/5th of existing quadripartion jumper clamp, can shorten strain rod tower cross-arm interlamellar spacing and cross-arm length, and saved the material of wire clamp, profile is more attractive in appearance, succinct, 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.
