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
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.
