Description
Technical field
The present invention relates to a kind of bolt type and regulate elbow, be specifically related to a kind of overhead transmission line bolt type rigid jumper with regulating elbow, belong to overhead transmission line gold utensil technical field.
Background technology
Since the reform and opening-up, China's power industry is fast-developing, and particularly in recent years, along with growing continuously and fast of need for electricity, electric power development speed is further accelerated.Power industry is the basic industry that involves the interests of the state and the people.Optimizing the energy resources configuration, ensure national energy security, for national economy and social development provides high-quality, reliably supply of electric power, is that the important mission of building a harmonious socialist society is served in power industry.
Wire jumper is the important component part of transmission line, and its effect is the wire that connects the strain tower both sides.When electric pressure was low, the wire 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 steel 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 as much as possible the tower head size, saving steel reduces cost, and former 500kV circuit flexible jumper commonly used can not satisfy extra high voltage line wire jumper demand.
The wire jumper that the extra high voltage direct current transmission line engineering adopts is generally the rigid jumper structure, the wire jumper each several part keeps rational distance to steel 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 greatly 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, although using method is the same not to the utmost, but all exist common problem, be exactly that the flex point that occurs of the junction of rigid jumper and drainage thread is shaped bad, flex point place corona problem is difficult to solve.Aluminum pipe type rigid jumper wire 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 transmission line now is divided into two kinds, aluminum pipe type rigid jumper wire and cage rigid jumper.The aluminum pipe wire jumper mainly is the wire 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 wire.Aluminum pipe type rigid jumper wire has following advantage: the processing of aluminum pipe wire jumper is simple, easy construction, the aluminum pipe part can be in factory process and pre-assembled, aluminum pipe only need be installed during on-the-spot the installation is connected with conductor spacer to be connected with the termination wire jumper and gets final product, accelerate the installation rate of wire jumper, alleviated workman's work high above the ground labour intensity; Be electrically connected with one section short twisted wire between wire and aluminum pipe, 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, having increased the weight of the weight of wire jumper, having increased the vertical component of system of jumping line, 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 jumper strings, can reduce like this alternate stress that the drainage thread root produces, and reduce wriggling tired.Because the aluminium tube type wire jumper has good practicality and economy, obtained using widely in the UHV transmission line engineering.
When adopting rigid jumper, wire jumper also comprises the aluminum tube supporting structure except comprising wire and conductor spacer.When line construction, owing to being subjected to the impact of structural shape, conductor rigidity and the circuit sub-conductor relative position etc. of strain tower, the sub-conductor moulding after installing in the wire jumper is often neat not as circuit, and " dog leg " phenomenon easily occurs.This not only causes wire jumper sub-conductor surface electric field intensity powerful than circuit sub-conductor surface field, makes wire jumper easily produce corona, and needs to adjust the sub-conductor position, has reduced efficiency of construction, causes the waste of wire and gold utensil.
