A kind of ultra high voltage stockbridge damper
The utility model relates to a kind of ultra high voltage stockbridge damper, belongs to power engineering apparatus field.
The stockbridge damper that China's many overhead transmission lines adopt departs from its installation site, thus lose antihunt action, transmission line is long-time running under these conditions, wire will produce disconnected stock, broken string under vibration stress, have a strong impact on the safe operation of transmission line, wire is installed the appearance that stockbridge damper can effectively overcome the above problems.Along with being on the increase of construction of the extra-high transmission line of China, large-section lead continuous application in the line, had new higher requirement to the performance of stockbridge damper, the demand while being applicable to large-section lead with the stockbridge damper of stronger anti-corona performance is also more and more obvious.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ultra high voltage stockbridge damper, this stockbridge damper is applied in transmission line, have the wire installed and stronger hold power, will it be made to depart from installation site because of the Long-term Vibration of wire, there is antihunt action more reliably, the safe operation of abundant guarantee overhead transmission line, it has self higher anticorona performance simultaneously, is therefore better applicable to the application in UHV transmission line.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of ultra high voltage stockbridge damper, this stockbridge damper comprises steel hoist cable, wire clamp, tup, sleeve pipe; Described wire clamp comprises bearing pin, wire clamp gland, wire clip body, bolt, nut, plain washer, spring washer and rubber blanket, the wire casing of described wire clamp gland is provided with protruding A, the wire casing of wire clip body is provided with protruding B, and described wire clip body lower end is provided with hole, and described tup is provided with bellmouth; Described steel hoist cable two ends are connected with the bellmouth riveting on tup by sleeve pipe, described steel hoist cable passes wire clamp lower end and passing hole and wire clamp are fixed, the upper end of described wire clip body and the upper end of wire clamp gland adopt hinge, described wire clamp gland and wire clip body respectively by protruding A and protruding B and rubber blanket and wire is installed rubber pressing after, pressing plate is blocked by pin, thus wire of holding with a firm grip, the bolts and nuts then in described wire clip body are fixed by plain washer and spring washer and wire clamp gland.
Further, described tup end is circular shape, and transition is round and smooth.
Further, the described tup end first half and the latter half are unsymmetric structure.
Further, the shape in described hole, size match with described steel hoist cable.
The beneficial effects of the utility model:
Stockbridge damper of the present utility model can suppress the aeolian vibration of wire in overhead transmission line effectively, achieve large-section lead to install and the requirement of the anticorona performance of ultra high voltage gold utensil self, have that novel structure uniqueness, stable and reliable working performance, rapid operation are simple and easy to do, considerable benefit, convenient transport, be applicable to industry and the advantage such as widely popularize.

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in figs. 1-7, a kind of ultra high voltage stockbridge damper, this stockbridge damper comprises steel hoist cable 1, wire clamp 2, tup 3, sleeve pipe 4; Described wire clamp 2 comprises bearing pin 5, wire clamp gland 6, wire clip body 7, bolt 8, nut 9, plain washer 10, spring washer 11 and rubber blanket 12, the wire casing of described wire clamp gland 6 is provided with protruding A15, and the wire casing of wire clip body 7 is provided with protruding B16, described wire clip body 7 lower end is provided with hole 13, and described tup 3 is provided with bellmouth 14; Described steel hoist cable 1 two ends are connected with bellmouth 14 riveting on tup 3 by sleeve pipe 4, described steel hoist cable 1 is through wire clamp 2 lower end and passing hole 13 is fixing with wire clamp 2, the upper end of described wire clip body 7 and the upper end of wire clamp gland 6 adopt bearing pin 5 hinged, described wire clamp gland 6 and wire clip body 7 are respectively by after protruding A15 and protruding B16 and rubber blanket 12 and the rubber pressing being provided with wire, pressing plate is blocked by pin, thus wire of holding with a firm grip, the bolt 8 then in described wire clip body 7 is fixed by plain washer 10 and spring washer 11 and wire clamp gland 6 with nut 9.
Further, described tup 3 end is circular shape, and transition is round and smooth.
Further, the described tup 3 end first half and the latter half are unsymmetric structure.
Further, the shape in described hole 13 matches with described steel hoist cable 1 with size.
During use, shockproof hammer thread clip main body 7 and wire clamp gland 6 adopt bearing pin 5 hinged, protruding A15 in the wire casing of wire clip body 7 and wire clamp gland 6 and protruding B16 is also furnished with rubber blanket 12, wire clamp gland 6 and wire clip body 7 by wire is installed rubber pressing after, pin blocks pressing plate, thus wire of holding with a firm grip.Wire clip body 7 is furnished with the hole 13 of matching with steel hoist cable 1, and steel hoist cable 1 is through hole 13, and the both sides of steel hoist cable 1 respectively configure a tup 4.Steel hoist cable 1 two ends are connected with bellmouth 14 riveting on tup 1 by sleeve pipe 4.Larger circular arc is made in anti-vibration hammer 3 end, and transition is round and smooth, and in order to ensure vibrationproof characteristic, adjustment centroid position, can shorten wire clamp 2 height simultaneously, the tup 3 end first half and the latter half have been made unsymmetric structure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
