Abstract
The utility model discloses a combined type damper for an overhead power transmission line. Small hammers with the same type are combined into a heavy hammer; and by optimally combining various dampers with different frequency characteristics, a group of dampers have straighter frequency characteristics, wide covering range and more effective damping effect, weakens the fatigue damage, improves the operation stability of the line and prolongs the service life of the line.
Description
Technical field
The utility model relates to a kind of overhead transmission line stockbridge damper, specifically, is the combined stockbridge damper of a kind of overhead transmission line.
Background technology
The lead of overhead transmission line is referred to as the vibration of lead owing to reasons such as the effect that is subjected to external force such as wind, ice, corona cause the periodic vibration of lead, and the vibration on transmission line at present mainly contains aeolian vibration, waves, deices jump, inferior span vibration etc.Lead is in the fatigue that these states will cause lead for a long time, causes conductor cord disconnection or disconnected thigh, makes the operation of circuit have very big potential safety hazard.Now the method for using is to install stockbridge damper additional preventing its vibration on cable, but because actual environment is complicated, traditional stockbridge damper can not satisfy the vibration damping requirement of circuit operation far away.How reducing effectively or being controlled at the fatigue damage that produces owing to vibration in service of circuit under the complex environment is the problem of needing solution at present badly
Summary of the invention
The purpose of this utility model provide a kind of compact conformation flexibly, use simple installation, vibration proof superior performance, effectively reduce the novel combined stockbridge damper of lead fatigue damage.
The utility model adopts following technical scheme:
The combined stockbridge damper of a kind of overhead transmission line comprises wire clamp pressing plate and hammer body, and hammer body is made up of a pair of tup and steel strand wire, a pair of tup is connected to the two ends of steel strand wire, the wire clamp pressing plate is connected with hammer body, and the wire clamp pressing plate also connects a hammer body at least again except that a hammer body that has connected.
The shape of described hammer body and/or size difference.
Described wire clamp pressing plate is connected with the steel strand wire of hammer body, and connected mode is crimping.
Described wire clamp pressing plate is made up of at least two block pressur plate pieces, fixes by round head square neck bolt between the pressing plate.
Compared with prior art, the utlity model has following advantage:
1, the utility model frequency coverage is wide.Broken the pattern that one section steel strand wire of transmission line tradition stockbridge damper are chosen two tups, combination according to 3 kinds of different frequencies (high frequency, intermediate frequency, low frequency), 3 kinds of stockbridge damper optimum organizations are got up, make one group of stockbridge damper have more straight frequency characteristic, wide coverage.
2, the utlity model has significant vibration proof performance.The power of combined stockbridge damper does not reach the summation of its each single hammer consumption power, and when the stockbridge damper of same quantity was installed, the utility model was more effective to vibration damping, the vibration-isolating effect of system, can extension wire operation stability and life-span.
But 3, the utility model simplified design and construction and minimizing operation maintenance workload.Because the utility model frequency characteristic coverage is wider, apply to cross in the transmission line and can cancel damping wire, and then convenient design and construction.
4, the utility model provides a kind of new solution route for the circuit vibration proof, adopts and is combined into weight with the form hand hammer, efficiently solves to improving high band vibrationproof performance and requiring the bigger contradiction of stockbridge damper weight ratio.
5. the utility model adopts round head square neck bolt to make stockbridge damper possess good anticorona characteristic, and the existing stockbridge damper of energy-saving effect is more remarkable.

Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with Figure of description:
Embodiment as shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is the combined stockbridge damper of a kind of overhead transmission line, comprise wire clamp pressing plate 1 and three hammer bodies, every hammer body is made up of a pair of tup 2 and steel strand wire 3, and tup 2 is connected to the two ends of steel strand wire 3, and steel strand wire 3 adopt high strength steel strand, tup 1 adopts the tuning-fork-type tup, perhaps also can adopt the tup of other shape, be crimped on the two ends of steel strand wire 3 respectively, the identical but size dimension difference of the shape of every hammer body; Wire clamp pressing plate 1 constitutes the wire clamp pressing plate jointly by three block pressur plate pieces, perhaps also can adopt the clamp block of different numbers, all connects a hammer body on each block pressur plate piece, and steel strand wire 3 crimping of clamp block and hammer body are fixed.
Connected by bolt between the clamp block, bolt adopts round head square neck bolt to prevent corona, connects the lead of holding with a firm grip by the bolt between the clamp block, thereby stockbridge damper is fixed on the overhead transmission line.
The beneficial effect of present embodiment be the stockbridge damper compact conformation flexibly, use simple installation, vibration proof superior performance, effectively reduce the lead fatigue damage.
