Description
Affiliated technical field
The utility model relates to a kind of UHV transmission line six division cage rigid jumper devices, and wire jumper adopts the continuous lead current-carrying of the six roots of sensation, and its parts mostly are hidden in the bundle conductor, can effectively avoid the generation of corona.
Background technology
In the ultra high voltage aerial power transmission line, the drainage bridle wire apparatus of strain tower is to be used for connecting the lead that the iron tower both sides link to each other with insulator string, and it is continuous to be conductively connected.When electric pressure is low, the lead of adjacent strain section generally all adopts flexible conductor to connect, rising along with electric pressure, 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.For the windage yaw that limits wire jumper is waved, wire jumper is designed to the structure of rigidity, thereby can reduces the tower head size, reduce track investment.
When adopting rigid jumper, the wire jumper each several part keeps rational distance to iron tower ground connection, thereby reduces the sag of wire jumper, and owing to the rigidity of wire jumper, under the wind-force effect, its rocking tendency can significantly reduce, and therefore, can shorten the length of cross-arm simultaneously.Also install and use in the domestic 750KV supertension line, confirmed the validity and the practicality of rigid jumper.Through taking all factors into consideration the applicable cases of past at 500kV, 750kV circuit: the female wire jumper of aluminum tube is in the 750kV line applications, and corona phenomenon is comparatively serious.
Summary of the invention
Mainly by drainage thread (1), stay pipe (2), six division hood type jumper wire spacing rods (3), weight sheet links such as (4) constitutes the rigid jumper device.Drainage thread (1) passes six division hood type jumper wire spacing rods (3), is provided with six division jumper wire spacing rods (5) on drainage thread (1), is provided with suspension member on stay pipe (2).
In order to forming six division hood type jumper wire spacing rods of cage type, owing to become the anchor ear structure with the fixing partial design of stay pipe, but the distance regulated at will between per like this two conductor spacers guarantees that whole cage type the waist phenomenon of collapsing can not occur, on-the-spot easy for installation.In addition, because the utility model is a rigid structure, has limited the windage yaw of wire jumper and waved.
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 corona, has guaranteed electric property of the present utility model.
The technical scheme in the invention for solving the technical problem is:
The utility model provides a kind of UHV transmission line six division cage rigid jumper devices: shaft tower both sides strain insulator-string drainage plate is connected with flexible jumper, adopt 6 continuous sub-conductor drainages, six division jumper wire spacing rods are installed, the interval of finishing the both sides flexible jumper on the flexible jumper of both sides; Interlude at wire jumper uses fixedly six roots of sensation line of rigid jumper device, to form mouse cage.Adopt two simply connected V-arrangement strings that it is suspended on the shaft tower simultaneously.
Conductor spacer on the whole mouse cage spider is designed to the split hood type.The hood type conductor spacer is held head part and is used by aluminium alloy and make, and the rubber blanket that wire clamp inner lining protection twisted wire is used is in order to the clamping wire jumper.Hood type conductor spacer installation site is flexible, can move arbitrarily along stay pipe along line direction, also can move towards adjusting angle according to flexible jumper perpendicular to line direction.Wire clamp chuck end portion has adopted arc transition simultaneously, can effectively avoid the generation of corona.
Whole rigid jumper device adopts circular steel pipe as the skeleton matrix, and the spider stay pipe of cage body adopts the seamless steel pipe manufacturing.For the ease of transportation, whole cage type spider stay pipe is divided into three sections, adopts ring flange to link to each other bolted between three sections.Suspension member adopts two simply connected V-arrangement string structures, and what the link plate that is connected with stay pipe adopted is hood type.
For preventing that wire jumper is swung by the external force effect, can install weight sheet (4) additional as required on stay pipe.The weight sheet is cylinder iron made, and its structure is designed to U type open type, is fixed on the stay pipe by stud and clamping plate.Easy for installation, can after installing, install whole bridle wire apparatus.
The beneficial effects of the utility model are:
1. after adopting the cage type rigid jumper, limit the windage yaw of wire jumper and waved, reduced the tower head size, reduced track investment.
2. used six division conductor spacers of hood type, but the distance regulated at will between per like this two conductor spacers guarantees that whole cage type the waist phenomenon of collapsing can not occur, on-the-spot easy for installation.
3. stay pipe adopts syllogic, is convenient to transportation, and is easy for installation.
4. the weight sheet adopts U type, convenient and flexible installation.
