Abstract

The invention discloses a wire spacer for preventing wind-induced vibration of a high-voltage power transmission line. The wind spacer comprises a frame and a plurality of cable clamps evenly distributed on the circumference of the frame, wherein the cable clamps consist of wire blocking claws, vibration damping rods and socket sleeves; each vibration damping rod consists of a step shaft, two springs respectively sleeved at two ends of the step shaft and a spring sleeve; the front section and the rear section of the step shaft are different in length; one end of the sleeve is a tightening hole, the sleeve is sleeved on the long shaft rod and is in clearance fit with the long shaft rod, the other end of the sleeve is fixedly connected with the socket sleeve; the long shaft rod end of the step shaft is connected with the handle part of the wire blocking claw; the short shaft rod end of the step shaft has a section of axial movement clearance in the sleeve; the tail end of the socket sleeve is hinged with the edge of the frame. The wind spacer can resist high wind in different directions, prevent wires from vibrating, and also can effectively reduce the vibration frequency and intensity of wires, even if the wind speed reaches about 25m/s.

Description

The windproof vibration conductor spacing device that lures of ultra-high-tension power transmission line
Technical field
The present invention relates to a kind of spacer that is used in keeping parallelism wire pitch on the ultra-high-tension power transmission line, particularly a kind of and have a windproof conductor spacing device that lures vibration.
Background technology
The overhead transmission line fault is many is induced the line vibration and is risen by wind.Wind lure vibration to the destruction of transmission line except tripping operation, electric arc burn are ironed in alternate sudden strain of a muscle, the more important thing is that it makes lead, link and iron tower all bear bigger dynamic load, when load surpasses certain limit, associated components will be damaged, the safe and stable operation of serious threat electrical network.Along with heavy in section, the development of dividing overhead transmission line more, wind lures vibration accidents caused frequent, although there is multiple wind resistance to lure the conductor spacing device of vibration now, but they are only applicable to the overhead transmission line in low wind speed area about 5m/s, and only the wind energy that heads on is cushioned, when wind speed is big, particularly when the strong wind direction frequently changes, these spacers just are difficult to deal with, even can't prevent that at all wind from luring the generation of vibration.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing high-voltage power line conductive line spacer, propose a kind of conductor spacing device that can resist strong wind and can effectively prevent the vibration of different wind directions initiation lead.
The technical scheme that realizes above-mentioned purpose is: the windproof vibration conductor spacing device that lures of a kind of ultra-high-tension power transmission line, comprise circular plate frame and a plurality of wire clamps that are distributed on the framework circumference, it is characterized in that: described wire clamp is by the card line pawl of leading portion, the buffer beam in stage casing and the cover for seat of back segment are formed, described buffer beam is made up of with two springs and a spring spool of being set in these step axle two ends the axostylus axostyle of step a centre, two sections of the front and back of described step axle are not isometric, one end of described sleeve is for tightening up mouth, it be sleeved on the long section axostylus axostyle and with its formation matched in clearance, the inner face that tightens up mouth is connected to the spring other end of growing on the section axostylus axostyle, the other end of sleeve is fixedlyed connected with cover for seat, the long shaft rod termination of step axle is connected with the shank of card line pawl, there is one section axial play the stub shaft termination of step axle in sleeve, the tail end of cover for seat and the leg of frame are along hinged.
A kind of improvement as above-mentioned technology: the junction of described cover for seat tail end and framework adds rubber sleeve, and this rubber sleeve can make turning joint place of spacer also can weaken wind and lure oscillation energy.
Another improvement as above-mentioned technology: one group of stockbridge damper is installed on the described plate frame central axis, and this stockbridge damper can further improve the anti-vibration performance of spacer.
Another improvement as above-mentioned technology: the pawl core position of described card line pawl adds rubber blanket, and this rubber blanket not only makes card line pawl that lead is had bigger curable grip, and lures vibration to have certain damping action to wind.
The present invention can resist the different directions strong wind, prevents the lead concussion, even wind speed reaches about 25m/s, also can effectively reduce the frequency and the intensity of lead vibration.If each the regulation mid span in the 750KV UHV transmission line is installed a spacer of the present invention, then can guarantee the safe and stable operation of this circuit.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the present invention a kind of six windproof schematic diagram that lures vibration conductor spacing device of ultra-high-tension power transmission line at interval.This spacer totally is made up of circular plate frame 1 and the stockbridge damper assembly 11 that is distributed in six wire clamps 2 on the framework circumference and be positioned on framework 1 axis.Wherein:
Circular plate frame 1 is formed (as shown in Figure 2) by former and later two flat boards just as shape.
Each wire clamp 2 is made up of the card line pawl 3 of leading portion, the buffer beam 4 in stage casing and the cover for seat 5 of back segment.Buffer beam 4 is made up of with 71, the 72 and spring spools 8 of spring that are set in these step axle two ends a step axle 6 as shown in Figure 6.Two sections of the front and back of step axle 6 are not isometric, and spring 71 is sleeved on the long shaft rod 61, and spring 72 is sleeved on the stub shaft 62; One end of spring spool 8 is for tightening up mouth, it be sleeved on the long shaft rod 61 and with its formation matched in clearance, the inner face that tightens up mouthful is connected to spring 71 other ends; The other end of spring spool 8 is fixedlyed connected with cover for seat 5 and is made the inner bottom surface of cover for seat 5 be against the other end of spring 72; The front end of step axle 6 is that the front end of long shaft rod 61 is connected with the shank of card line pawl 3, and the follower head of step axle 6 is that stub shaft 62 follower heads have one section axial play in spring spool 8, as shown in Figure 3; The tail end of cover for seat 5 is hinged on the position, edge between framework 1 front and rear panel, as shown in Figure 2.
The above-mentioned structure of buffer beam 4 makes wire clamp 2 have two-way restoring force on it is axial.When front wind came, spring 62 was stressed, the concussion of damping lead; When back side wind came, spring 61 was stressed, same damping lead concussion.Therefore, spacer of the present invention can be resisted the different directions strong wind, prevents the lead concussion
In the present embodiment, the junction between cover for seat 5 tail ends and framework 1 front and rear panel adds rubber sleeve 9, one group of stockbridge damper assembly 11 is installed, as shown in Figure 2 on plate frame 1 central axis; The pawl core position of card line pawl 3 adds rubber blanket 10, as shown in Figure 4 and Figure 5.Such design can further strengthen the windproof vibration ability that lures of spacer of the present invention.
