Abstract
The utility model relates to a vibration-proof structure of a power/communication OPGW communication line. An OPGW communication line body is provided with nodes of a fixed span, each span of the OPGW communication line is provided with a damping wire, the two ends of the damping wire are respectively fixed with the two ends of the line of the span via wire clamps, the length of the damping wire of each span is greater than the length of the OPGW communication line of the span, and the damping wire is arc-shaped. The OPGW communication line body is provided with at least one vibration-proof damper. The vibration-proof structure can greatly reduce the vibration amplitude of the OPGW line in wind, and weaken fatigue damage of breeze vibration on optical cables.
Description
Technical field
The utility model relates to a kind of shockproof structure of power circuit.
Background technology
Overhead ground wire composite cable OPGW circuit is fully utilized at present, and a large amount of power communications utilizes existing OPGW circuit to be achieved the transmission of power communication signal at present.Aeolian vibration is a kind of eddy current backflow phenomenon that often occurs in OPGW circuit.The theory of mechanics of aeolian vibration is that the wind of stablizing layering occurs during by cylindrical object.In the time of wind cylindrical object, the staggered eddy current of its layering below capable become certain pressure differential, so just make cylindrical object produce the trend of movement with the perpendicular direction of the moving direction of wind.If when the natural frequency of the frequency of eddy current and optical cable is consistent, will there is aeolian vibration in wire.This aeolian vibration produces tired harm to optical cable.
Utility model content
The utility model, for the deficiencies in the prior art, provides one can greatly reduce OPGW circuit Oscillation Amplitude in wind, reduces the fatigue harm that aeolian vibration produces optical cable.
The utility model is achieved through the following technical solutions:
Power communication OPGW communication line vibration-proof structure, comprise OPGW communication line body, OPGW communication line body is provided with the node of fixing span, on the each span of OPGW communication line, damping wire is installed, the circuit two ends of the two ends of damping wire and each span are fixed together by wire clamp, between each span, the length of damping wire is greater than OPGW communication line length between each span, and damping wire forms arc shape.
Power communication OPGW communication line vibration-proof structure, described OPGW communication line body is provided with at least one stockbridge damper.
Power communication OPGW communication line vibration-proof structure, described damping wire is steel reinforced aluminium conductor.
Power communication OPGW communication line vibration-proof structure, the little tup of described stockbridge damper is towards steel tower.
Power communication OPGW communication line vibration-proof structure, between described each span damping wire length be described communication line length 1.5-2 doubly.
Its arch section of the utility model damping wire can by the vibration wave in span with and energy be delivered near wire clamp, consume the energy of vibration wave through the self-damping of damping wire, vibration is significantly weakened, reach and cut the effect of shaking.Between each span damping wire length be communication line length 1.5-2 doubly, can reach so best damping effect.Stockbridge damper is installed and can be further made up the frequency range that damping wire cannot cover, make it possible to better reduce even to eliminate aeolian vibration.Thereby reduce the fatigue harm that aeolian vibration produces optical cable.
Accompanying drawing explanation
Fig. 1 is structural representation.
Embodiment
Shown in accompanying drawing.
The utility model power communication OPGW communication line vibration-proof structure, comprise OPGW communication line body 1, OPGW communication line body 1 is provided with the node of fixing span, on the each span of OPGW communication line 1, damping wire 3 is installed, damping wire 3 is steel reinforced aluminium conductor, the circuit two ends of the two ends of damping wire 3 and each span are fixed together by wire clamp 5, and between each span, the length of damping wire 3 is greater than each span OPGW communication line 1 length, and damping wire 3 forms arc shape.OPGW communication line body 1 is provided with stockbridge damper 2 on the OPGW of each span communication line, and the little tup of stockbridge damper 2 is towards steel tower 4.The arch section of the utility model damping wire 3 can by the vibration wave in span with and energy be delivered near wire clamp 5, consume the energy of vibration wave through the self-damping of damping wire 3, vibration is significantly weakened, reach and cut the effect of shaking.Stockbridge damper 2 is installed and can be further made up the frequency range that damping wire 3 cannot cover, make it possible to better reduce even to eliminate aeolian vibration.
