Abstract
The utility model discloses a bolted damper for an overhead transmission line, which comprises a line clamp body and a line clamp cover plate, wherein the line clamp body and the line clamp cover plate are connected together by a fastening piece. Upon installation, the line clamp cover plate is opened relatively to the line clamp body but not separated. The damper is compact and flexible in structure and convenient and safe in installation. Reasonable design of the line clamp body and the line clamp cover plate that are applicable to line diameter range and the use of high-quality high-strength stainless steel fastening piece guarantee enough and durable grip of the damper line clamp to lines and meet the requirement of transmission line for long-term use. A damper head and a steel stranded wire are fixed by pressure-welding technique, form sufficiently firm contact and increase the grip of the damper head to the steel stranded wire. The optimized design of product appearance, including the shielding design of the line clamp body stiffener to bolts, and the use of non-magnetic anti-corrosion material causes the damper to have outstanding energy-saving effect and excellent corrosionresistance.
Description
Technical field
The utility model relates to a kind of overhead transmission line stockbridge damper, relates in particular to a kind of stockbridge damper that had not only prevented the sliding and corrosion of pine but also energy-saving effect is arranged.
Background technology
The aeolian vibration of overhead transmission line conductor is to threaten one of key factor of transmission line safe operation, by stockbridge damper is installed on lead, can effectively reduce the aeolian vibration level of lead, and it is suppressed in the safe range.
Present widely used stockbridge damper exists the stockbridge damper wire clamp to be difficult for holding with a firm grip lastingly lead owing to multiple reasons such as himself structure and installations, and then the stockbridge damper phenomenon of loosening slippage on the line takes place.Stockbridge damper has the design and installation position of its regulation on transmission line, in case after the slippage, will completely lose its vibration-isolating effect, if untimely discovery is also corrected, finally cause the vibrating fatigue of overhead transmission line conductor to be destroyed possibly.
Present widely used stockbridge damper is owing to multiple reasons such as himself structure and materials, and the loss of electric energy such as ubiquity corona, magnetic hysteresis eddy current can not have been satisfied the energy-conserving and environment-protective requirement that transmission line improves day by day.
Summary of the invention
The purpose of this utility model provide a kind of compact conformation flexibly, use simple installation, novel locking energy-saving vibration prevention hammer that grip is enough and lasting.
The utility model adopts following technical scheme:
A kind of overhead transmission line bolt type stockbridge damper, comprise wire clip body and wire clamp cover plate, wire clip body and wire clamp cover plate link together by securing member, and the wire clamp cover plate is fully opened the back and is not separated with wire clip body, the below crimping of wire clip body is steel strand wire fixedly, steel strand wire two ends crimping fixed hammer and tup.
Wire clamp adopts non magnetic high-strength aluminum alloy material, and securing members such as connecting bolt adopt non magnetic austenitic stainless steel, and tup adopts the allumen material.
Compared with prior art, the utlity model has following advantage:
1, the utility model compact conformation is flexible, uses simple installation safety.Because nut is fixed on the wire clip body with fashion of extrusion and does not drop, and hang in the process of lead opening the wire clamp cover plate, the wire clamp cover plate does not separate with body, after directly tight a bolt and get final product.
2, the utility model can guarantee enough and lasting grip, can satisfy the long-term instructions for use of transmission line.Because wire clamp is suitable for the appropriate design of wire range, avoid big wire casing to join little lead, to strengthen the contact area of wire clamp and lead, increase stiction, and select the high-strength stainless steel fastening of high-quality for use, therefore not only can guarantee the grip that requires, and can keep its original grip constant for a long time, prevent the loosening slippage of stockbridge damper.
3, tup of the present utility model and steel strand wire adopt compression joint technique to fix, and have avoided the flanging process and the casting of metals technology of relative complex, and between steel strand wire and tup because of crimping can form abundant firm contacting, increased the grip of tup to steel strand wire.
4, the utlity model has obvious energy-saving effect.Wire clamp adopts non magnetic high-strength aluminum alloy material, securing members such as bolt adopt non magnetic austenitic stainless steel, greatly reduce the loss of magnetic hysteresis eddy current electric energy, and the slyness of wire clamp and tup design, the wire clip body reinforcement is to the Shielding Design of bolt, corona is no longer produced, and comparing traditional stockbridge damper more has energy-saving effect.
5, the utlity model has superior decay resistance.Because wire clamp adopts aluminum alloy material, securing members such as bolt adopt stainless steel, and tup adopts the allumen material, makes product more corrosion-resistant, are fit to the use than heavily contaminated or coastal area.

Fig. 2 does not separate schematic diagram with wire clip body after the wire clamp cover plate is opened.
Fig. 3 is the fixing and shielding bolt schematic diagram of nut extruding.
Embodiment
A kind of overhead transmission line stockbridge damper, comprise wire clip body 1 and wire clamp cover plate 2, wire clip body 1 and wire clamp cover plate 2 link together by securing member 3, and wire clamp cover plate 2 is fully opened the back and is not separated with wire clip body 1, the below crimping of wire clip body 1 is steel strand wire 4 fixedly, steel strand wire 4 two ends crimping fixed hammer 5 and tups 6.Wire clip body 1 is a reinforcing rib structure, and wherein 7 is reinforcement, the bolt of bolt fastener 3 can be shielded in structure.Tup 5 and tup 6 are tuning fork shape, and the kirsite material, and fix with steel strand wire 4 crimping.
The utility model overhead transmission line stockbridge damper comprises the wire clip body 1 and the wire clamp cover plate 2 that link together by securing members such as bolt 3, and wire clamp cover plate 2 is opened, and hangs lead, directly tights a bolt and closes tight cover plate.
