Abstract
The invention relates to a transmission line fitting in a power system, and particularly relates to a torsional damper, which comprises a short steel stranded wire and cast ion hammer heads connected at two ends of the short steel stranded wire. Wire clamping plates are connected onto the short steel stranded wire; the wire clamping end of each wire clamping plate is semicircular; and transverse ends at two sides of each wire clamping plate are provided with slopes. Through improvement on the wire clamps of the torsional damper respectively, a non-barrier type structure is formed, and a non-barrier channel is built in the entire line. As for the improvement, the mechanical performance and the electrical performance of a ground line are not changed, demands of high-efficiency line patrol by a robot can be met, the robot can pass through the obstacle in a though mode rather than in a jumping mode, safety of operation of the robot is improved, and patrol efficiency is improved.
Description
technical field
The present invention relates to a kind of electric power system power transmission line accessory, i.e. stockbridge damper.
Background technology
In the prior art, the effect of the meteorological conditions such as overhead power line wind-engaging, ice, low temperature, makes circuit produce vibration and dynamic dance.Vibration frequency is higher and amplitude is very little, and wind vibration makes overhead wire at suspension point place repeatedly by stubborn folding, causes fatigue of materials, finally causes disconnected stock, line-outage contingency.The frequency of waving is very low, and amplitude is very large, is easy to cause alternate flashover, causes the serious accidents such as line tripping, power failure or burn wire.Conventional stockbridge damper is carried additionally at circuit tower bar suspension point place, to absorb or damping vibration energy, changes circuit wobble frequency, prevents the vibration of circuit or wave.The resonance that stockbridge damper causes for eliminating circuit self-vibration and elimination wind etc.
Aerial high-voltage power transmission line is the important component part of electrical network.At present, the tour mode of patrolling and examining of transmission line mainly adopts artificial line walking, and domestic also have the transmission of electricity enterprise of only a few carrying out the experiment work with helicopter routing inspection 500kV circuit.
Robot line walking becomes possibility at present, but on overhead wire, stockbridge damper and suspension clamp are that it hinders, in the process of transformation circuit, how to stockbridge damper and suspension clamp transformation, become unobstructed type structure, erecting unobstructed passage, is the needs promoting the efficient line walking of robot.
Summary of the invention
The object of the invention is for above-mentioned deficiency and a kind of stockbridge damper be convenient to robot line walking and passed through is provided.
Technical solution of the present invention is: stockbridge damper, comprises the cast iron tup that short steel strand wire are connected with its two ends, short steel strand wire are connected with clamp, and clamp plate holder conductor wire end is semicircle, and the horizontal end band in every block clamp both sides has domatic.
Advantage of the present invention is: by respectively to the improvement of stockbridge damper wire clamp, become unobstructed type structure, thus unobstructed passage is erected on whole piece circuit, this is improved, does not all change mechanical property and the electric property of ground wire, meet the demand adapting to the efficient line walking of robot simultaneously, realize the robot mode of passing through to break the barriers, and without the need to leap mode across obstacle, thus both improve the fail safe that robot runs, also improve and patrol and examine efficiency.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is Fig. 1 side structure sketch.
Embodiment
See Fig. 1,2, parts title is as follows: steel strand wire 1, cast iron tup 2, clamp 3, and semicircle 4, domatic 5, wire 6.
See Fig. 1,2, stockbridge damper, comprises the cast iron tup 2 that short steel strand wire 1 are connected with its two ends, and short steel strand wire 1 are connected with clamp 3.Clamp 3 presss from both sides conductor wire end for semicircle 4, and the horizontal end band in every block clamp 3 both sides has domatic 5.
Time stockbridge damper is clipped on wire 6, form the semicircle cambered surface of projection a little on wire 6 surface, semicircle cambered surface two ends have domatic, and this structure is convenient to robot roller (as wire rope pulley, centre is concave arc groove) by reducing obstacle.
