Description

A kind of anticorona aluminum pipe conductor spacer
Technical field
The utility model relates to a kind of anticorona aluminum pipe conductor spacer, is specifically related to the anticorona aluminum pipe conductor spacer of a kind of overhead transmission line, belongs to overhead transmission line gold utensil technical field.
Background technology
Adopt wire jumper to connect between the strain section of ultra-high-tension power transmission line.When electric pressure was low, the lead of adjacent strain section generally all adopted flexible conductor to connect; Along with the rising of electric pressure, the wire jumper sag is also along with increase, in order to satisfy after the wire jumper windage yaw the electric clearance of body of the tower, needs to lengthen the cross-arm length of iron tower.Thereby reduce the wire jumper sag and the windage yaw deviant is to dwindle the effective ways of strain tower size, and wire jumper sag and skew depend mainly on the wire jumper of employing or the fixing mode of wire jumper.In order to dwindle the tower head size as much as possible, save steel, reduce cost, former 500kV circuit flexible jumper commonly used can not satisfy extra high voltage line wire jumper demand.Extra high voltage line needs the more wire jumper mode of science, and rigid jumper is exactly a kind of method preferably.When adopting rigid jumper, the wire jumper each several part keeps rational distance to iron tower ground connection, thereby reduce the sag of wire jumper, simultaneously, because the rigidity of wire jumper, under the wind-force effect, its rocking tendency can significantly reduce, therefore can shorten the length of cross-arm. abroad by actual testing authentication this result, installation and use in the domestic 750kV supertension line have also confirmed validity and the practicality of rigid jumper.Rigid jumper is the most complicated part of line construction, and its corona is more serious than general line hardware.Multiple rigid jumper form has also been used in the part of the 750kV of the Northwest transmission line and other engineering, though using method is the same not to the utmost, but all exist common problem, it is bad to be exactly that the flex point that occurs of the junction of rigid jumper and drainage thread is shaped, and flex point place corona problem is difficult to solve.Aluminum pipe formula rigid jumper is owing to its design feature, and the corona problem of aluminum pipe end is more serious than other form wire jumpers.The rigid jumper that uses on 500kV and the above electric pressure transmission line is divided into two kinds, aluminum pipe formula rigid jumper and squirrel-cage rigid jumper now.The aluminum pipe wire jumper mainly is the lead wire jumper that replaces conventional design with 2 horizontal aluminum pipes, and 2 horizontal aluminum pipes are separated by with conductor spacer.Two ends become a wire clamp, drainage thread, connection gold utensil etc. with four and link to each other with lead.Aluminum pipe formula rigid jumper has following advantage: simple, the easy construction of aluminum pipe wire jumper processing, the aluminum pipe part can be in factory process and pre-assembling, only need install during on-the-spot the installation behind aluminum pipe and the conductor spacer to be connected with the termination wire jumper and get final product, accelerate the installation rate of wire jumper, alleviated workman's work high above the ground labour intensity; Twisted wire with one section weak point between lead and aluminum pipe is electrically connected, and can be adapted to the length of various strain insulator-strings and the variation of circuit corner; A whole set of wire jumper shape is completely fixed, and forming effect is good, has beautified environment; Owing to after the aluminum pipe wire jumper counterweight, increased the weight of the weight of wire jumper, increased the vertical component of wire jumper system, the overall structure good stability; The inboard wire jumper gravity of corner is by the suspention pull bar, and the outside and middle phase gravity hang by two string wire jumper strings, can reduce the alternate stress of drainage thread root generation like this, and it is tired to reduce wriggling.
Because aluminum pipe formula wire jumper has good practicality and economy, obtained using widely in the UHV transmission line engineering.Aluminum pipe formula wire jumper is mainly by aluminum pipe, aluminium tube joint, the aluminum pipe conductor spacer, the suspention conductor spacer, the weight sheet, aluminum pipe terminal drainage gold utensil, the drainage wire clamp, several sections such as wire jumper insulator string are formed, rigid element is made up of two parallel aluminum pipes, distance needs to use the aluminum pipe conductor spacer with convenient suspention between aluminum pipe in order to keep, the position of opening middle side part outside aluminum pipe of the present common aluminum pipe conductor spacer that adopts, because this place's field intensity is bigger, the opening part that causes the aluminum pipe conductor spacer visual corona occurs easily in that UHV transmission line is in service, thereby causes corona power loss, radio interference, TV interference and noise jamming.
