Six-splitting separation rods are arranged on the steel clamp rack, and the current leading wires penetrate through the six-splitting separation rods. Soft jumper separation rods are arranged on the current leading wires, and the current leading wires are fixed by the soft jumper separation rods. A hanging component is arranged on the steel clamp rack. The hard jumper device achieves the purposes of simple structure and good corona discharge prevention property.
Description
Technical field
The utility model relates to a kind of bridle wire apparatus, relates in particular to the hard bridle wire apparatus of a kind of extra-high voltage direct-current six division squirrel-cage.
Background technology
The drainage wire jumper of strained angled tower is to be related to the very important member of extra high voltage network wire insulation suspension system reliability service, adopts wire jumper to connect between the strain section of ultra-high-tension power transmission line.When electric pressure is low, the lead of adjacent strain section generally all adopts flexible conductor to connect, along with the rising of electric pressure and the increase of wire jumper sag, in order to satisfy after the wire jumper windage yaw electric clearance to body of the tower, need the cross-arm length of lengthening iron tower, thereby increased tower head size and circuit width of corridor, thereby the windage yaw that has strengthened circuit is waved, also just limit the scope of application of flexible jumper device, can not satisfy the above high-tension line demand of 800kV.
Summary of the invention
The utility model provides the good extra-high voltage direct-current of a kind of performance simple in structure, anticorona six division squirrel-cage hard bridle wire apparatus.
The technical solution adopted in the utility model is as follows:
The hard bridle wire apparatus of a kind of extra-high voltage direct-current six division squirrel-cage, comprise drainage thread, the steel spider, on the steel spider, be provided with six division conductor spacers, drainage thread passes six division conductor spacers, on drainage thread, be provided with the flexible jumper conductor spacer, and drainage thread fixed by the flexible jumper conductor spacer, on the steel spider, be provided with suspension member.
Reasonablely be: suspension member of the present utility model comprises insulator, is provided with ball-eye in the upper end of insulator, is provided with U type link on ball-eye, is provided with socket-clevis eye in the lower end of insulator, is provided with link plate on socket-clevis eye.
Reasonablely be: the utility model is provided with the movable balance weight piece on the steel spider.
Compared with prior art, the utlity model has following advantage:
1, the utility model is simple in structure.Adopt this hard jumper wire construction of the utility model, with six roots of sensation drainage thread respectively six division conductor spacers from the steel spider pass, again the steel spider is suspended on the iron tower with suspension member, the electrical distance that has kept drainage thread and ground well, make that the drainage thread overcurrent is smooth and easy, avoid the appearance of local overheating phenomenon; Whole bridle wire apparatus is simple in structure, and cost is low, in addition, because the utility model is a rigid structure, has limited the windage yaw of wire jumper and has waved.
2, the anticorona performance of the utility model is good.Because in the utility model, drainage thread passes from six division conductor spacers respectively, so drainage thread itself forms the ring shielding body, can effectively shield the corona on the steel spider, has guaranteed electric property of the present utility model.The discharge inception voltage of whole device improves 260KV than the hard wire jumper of pipe matrix.
3, spider of the present utility model adopts steel material, and bending resistance is strong; Spider is the segmentation manufacturing, adopts chuck to connect between every section, connects on the one hand simply, on the other hand convenient transportation.
4, the utility model is provided with the movable balance weight piece on spider, the fast position of adjustable weight in use, thus reach the purpose of spider maintenance level, simple to operate.
