Abstract

The utility model relates to a conductor spacer that is used for splitting cophase wire on power transmission line comprises frame, frame tip through bolted connection's fastener, and its key feature is that frame end connection fastener department sets up the damping pad that both sides face all has the unsmooth tooth of central slope for cylindric cap to closing, cap inner wire clamp, the utility model discloses can effectively prevent corona phenomenon's emergence, the damping pad structure can ensure that the volume of compressed is a constant, has prolonged the life of damping pad and has kept good damping characteristic, the utility model discloses convenient operation, compact structure is reasonable, is the fabulous substitute product of current various forms conductor spacer.

Description

Conductor spacer

Technical field

The utility model relates to power circuit equipment technical field, relates in particular to a kind of conductor spacer that is used to divide on transmission line with phase conductor.

Background technology

Existing conductor spacer is according to the difference of its bundle conductor quantity, in-line, triangle, cross or quadrangle are arranged, its basic structure is that the wire clamp by framework and Qi Ge end constitutes, damping portion between framework and the wire clamp is made up of a plurality of rubber columns, axle sleeve and wire clamp plum blossom hole, and this structure is comparatively complicated, and requirement on machining accuracy is higher, manufacturing cost is also higher, from operating position, existing conductor spacer damping characteristic is relatively poor, the shock absorbing performance is bad, especially has the generation of corona phenomenon.

Summary of the invention

The purpose of this utility model is at existing conductor spacer above shortcomings, provides that a kind of damping characteristic is good, the shock absorbing performance is good and can effectively prevent the conductor spacer that corona phenomenon takes place.

The purpose of this utility model is achieved through the following technical solutions, a kind of conductor spacer, comprise that the framework and the end that have two ends at least connect solid wire clamp through bolt, it is characterized in that the frame ends setting is cylindric involutory cap, the Zhou Duan of cap is circular-arc, end face is cancave cambered surface, the damping arm of wire clamp places the both sides in the cap to be provided with the both sides end face all shaggy tooth, the all centroclinal damping pad of its concavo-convex flank of tooth, shaggy tooth respectively with adjacent cap in parietal tooth, damping arm tooth coincide, the lateral surface that the damping arm of wire clamp and cover plate are installed with bolt is provided with groove, and damping arm groove also is provided with the interior hexagonal corresponding with the nut of bolt.

The utility model is cylindric cap with the design of the end of framework, in the turning joint portion with wire clamp can being enclosed in, and the week of cap end and end face all design and be circular-arc, can prevent the generation of corona phenomenon effectively, play anticorona and lightning-arrest effect; The design of damping pad two sides introversion is considered wire clamp when doing axial motion, the characteristic that the decrement of outer ledge can be bigger than inside center decrement, thereby can guarantee that the compressed amount of damping pad is a constant; Groove and interior hexagonal are set on the wire clamp, and the bolt that can make connection is evagination not, and only can finish fastening work, handled easily with a spanner; The utility model compact conformation, reasonable is the existing fabulous substitute products of various types conductor spacer, can be widely used in the same phase conductor of division in the ultra-high-tension power transmission line.

Embodiment

The utility model is by framework 1, the cap 2 of framework 1 end, the wire clamp of forming by damping arm 3 and cover plate 4, the damping pad 6 of cap 2 internal damping arms 3 both sides and securing member constitute, needs according to bundle conductor quantity, framework 1 can be an in-line, it also can be triangle, it also can be quadrangle, each end of framework 1 all is provided with columned cap 2, except that the cap 2 of end, be I-shaped skeleton, cap 2 is made up of fixing two parts with activity, fasten through bolt 5, fixed part and framework 1 are one, the Zhou Duan of cap 2 is circular-arc, and its end face is cancave cambered surface, and cap 2 standing part inner faces are provided with location notch along center line, damping arm 3 afterbodys of wire clamp place in the location notch, and damping arm 3 tail end both sides equate with the diagonal pitch of opposite side location notch with the spacing on one side location notch both sides, place; 3 both sides of cap 2 internal damping arms are provided with damping pad 6, and all there is centroclinal shaggy tooth damping pad 6 two sides, and both sides shaggy tooth and adjacent cap 2 inboard shaggy tooths, damping arm 3 afterbody shaggy tooths coincide; The damping arm 3 of wire clamp connects solid with cover plate 4 through bolt 7, it is fluted that damping arm 3, cover plate 4 are installed with the lateral surface of bolt, the interior hexagonal that also has corresponding bolt 7 nuts in the groove of damping arm 3, help using a spanner can finish fastening work, the line portion of the wrapping up in two ends evagination of wire clamp prolongs, increased the contact area with institute's bundle conductor, got rid of the rubber blanket that use in existing wire clamp clamp place, the parcel lead is more firm.

Claims

1, a kind of conductor spacer, comprise that the framework and the end that have two ends at least connect solid wire clamp through bolt, it is characterized in that the frame ends setting is cylindric involutory cap, the Zhou Duan of cap is circular-arc, end face is cancave cambered surface, the damping arm of wire clamp places the both sides in the cap to be provided with the both sides end face all shaggy tooth, the all centroclinal damping pad of its concavo-convex flank of tooth, shaggy tooth respectively with adjacent cap in parietal tooth, damping arm tooth coincide, the lateral surface that the damping arm of wire clamp and cover plate are installed with bolt is provided with groove, and damping arm groove also is provided with the interior hexagonal corresponding with the nut of bolt.

2, conductor spacer according to claim 1 is characterized in that the cap of frame ends is made of fixed part and movable part two parts, and fixed part and framework are one.
