Description
Technical field
The utility model relates to the improvement of stockbridge damper wire clamp.
Background technology
Stockbridge damper is the protection gold utensil that is used to prevent the lead aeolian vibration on the aerial high-voltage power transmission line.The span of high pressure overhead power line is bigger; When the aerial condutor line receives the wind perpendicular to line direction; Will form the stabilizing vortex of pressing the certain frequency alternatively up and down at its lee face; Under the effect of eddy current lift component, make overhead wire in its vertical plane, produce periodic swinging (being the overhead wire vibration).When the lucky natural frequency of vibration with overhead wire of the frequency of eddy current is identical, will form the stable vibration ripple of overhead wire, this stable vibration wave will be at the inner alternate stress that produces of overhead wire, and long term can cause the damage of overhead wire.The most serious place is overhead wire wire clamp exit.
In order to prevent and to alleviate conductor vibration to its damage that causes, near the general stockbridge damper of the installation some suspension wire clamp.When vibration took place lead, stockbridge damper also moved up and down, and produces an even opposite effect power asynchronous with conductor vibration, can reduce the amplitude of lead, even can eliminate the vibration of lead.
As shown in Figure 1, stockbridge damper generally is made up of with wire clamp 13 tup 11, steel hoist cable (steel strand wire) 12, and wire clamp is fixed on the lead 4.The wire clamp of at present domestic stockbridge damper commonly used is the pressing plate type, is used for stockbridge damper is clamped in lead.As shown in Figure 2, this wire clamp 13 is made up of wire clip body 14 and pressing plate 15 two parts, and both separate.When mounted, wire clip body 14 combines fixing with clamping wire 4 with pressing plate 15 through bolt assembly 16.
Yet on high-tension line; Owing to reasons such as long-term swing, creeps, lead is tapered in wire clamp clamping place, and the bolt assembly on the wire clamp can not compensating wire and wire clamp between the gap and occur becoming flexible; Cause stockbridge damper along the lead slippage; The normal place that departs from stockbridge damper loses the effect of stockbridge damper, the serious lead that also can wear and tear.The stockbridge damper of while pressing plate molded lines folder, the gap of its wire clip body and pressing plate front end and support place is bigger, anticorona weak effect.
Summary of the invention
The technical problem that the utility model solves provides a kind of can preventing and uses the back to occur loosening and can not clamping wire and stockbridge damper wire clamp with preferable anticorona effect for a long time.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of stockbridge damper wire clamp, comprise wire clip body and pressing plate, and this wire clip body is provided with first wire casing; This pressing plate is provided with this first wire casing and cooperates to compress second wire casing of lead; This wire clip body and pressing plate are fixed through bolt assembly, wherein: be provided with the first rubber glue watt in first wire casing of said wire clip body, be provided with the second rubber glue watt in second wire casing of said pressing plate; Contact-making surface shape between said wire clip body and the said pressing plate cooperatively interacts (at utmost reducing slit between the two), and the external margin of said wire clip body and said pressing plate is a rounding off.After the pressing plate of existing stockbridge damper wire clamp and wire clip body are fixed through bolt assembly; Between the two ends of pressing plate and the wire clip body certain clearance is arranged; The utility model then can at utmost reduce gap between the two because the contact-making surface shape between wire clip body and the pressing plate cooperatively interacts; The outline that adds wire clip body and pressing plate all adopts the rounding off design, therefore can promote anticorona effect.
One of improve: be provided with first location notch in first wire casing of said wire clip body, the said first rubber glue watt is provided with and cooperates with this first location notch to fix first positioning boss of the said first rubber glue watt; Be provided with second location notch in second wire casing of said pressing plate, the said second rubber glue watt is provided with second positioning boss that cooperates with this second location notch with the fixing said first rubber glue watt.
Two of improvement: said wire clip body bottom is provided with the installing hole that is used for fixing the steel hoist cable, and the top of said wire clip body connects with an end of said pressing plate through hinge pin, and the other end of said pressing plate is fixedly connected with said wire clip body through bolt assembly.This hinge arrangement makes the cooperation of wire clip body and wire clamp pressing plate flexibly compact, easy for installation, and the wire clamp pressing plate rotates around hinge pin and gets final product.
Three of improvement: the top of this stockbridge damper wire clamp is rounded.Adopt the slick and sly structure of this sphere, can improve the ability of anticorona level, satisfy the anticorona requirement of ultra high voltage.
Compared with prior art, beneficial effect is: on the one hand, be provided with rubber glue watt in the wire clip body of the utility model and the wire casing of pressing plate, when the wire clamp clamping wire, rubber glue watt is compressed the storage elasticity energy.When the lead deformation of creep, watt release resilience of rubber glue, the gap of compensating wire and wire clamp guarantees the wire clamp grip force, prevents the stockbridge damper slippage effectively.On the other hand; Wire clip body is compared the wire clip body of existing stockbridge damper wire clamp and the gap between the pressing plate and is obviously reduced with the gap between the pressing plate; The external margin that adds wire clip body and pressing plate adopts the rounding off design, therefore can further prevent the high-voltage corona phenomenon, the protection stockbridge damper.
