Description
Technical field
The utility model relates to a kind of device preventing stockbridge damper positioning, belongs to field of electrical equipment.
Background technology
At present, along with the quickening of domestic industry paces, power circuit also increases thereupon, and overhead transmission line is widely used due to advantages such as cost are low, ability to transmit electricity is strong, is the chief component of China's electrical network.But the effect of the meteorological conditions such as overhead power line wind-engaging, ice, low temperature, makes circuit produce vibration and wave.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.For eliminating the resonance that circuit self-vibration and elimination wind etc. cause, needing to install stockbridge damper on transmission pressure and ground wire, because it carrys additionally at circuit tower bar suspension point place, to absorb or damping vibration energy, changing circuit wobble frequency, prevent the vibration of circuit or wave.Existing wire stockbridge damper to be caved in jaws clamping transmission pressure or ground wire by bolt.For making anti-rattler firm position, easily firmly excessive in installation process, make the stressed member of stockbridge damper produce metal fatigue; Wire expands with heat and contract with cold because temperature Change produces; Wind-force vibrations make stockbridge damper get loose, and these factors all easily make stockbridge damper occur positioning phenomenon.Cause shockproof effect to decline, threaten line security to run.For making stockbridge damper return fix, needing interruption maintenance, having a strong impact on power supply reliability, and maintainer need move to the positioning point of stockbridge damper on wire by instruments such as insulating ladders, maintenance workload and difficulty are comparatively large, and danger coefficient is higher.
Summary of the invention
The utility model object easily occurs positioning phenomenon in order to the stockbridge damper solved on overhead power line, affects the problem of power supply reliability, provide one and prevent stockbridge damper positioning device.
One described in the utility model prevents stockbridge damper positioning device, and aerial condutor is provided with insulator by wire clamp, arranges two stockbridge dampers in the bilateral symmetry of wire clamp,
The described stockbridge damper positioning device that prevents comprises two parallel groove clamps, two stockbridge damper fastening bolts, two annulus binding posts and metallic cable,
The two ends of metallic cable are provided with an annulus binding post, are fastened on two stockbridge dampers by annulus binding post by stockbridge damper fastening bolt, and then are fixed on by metallic cable between two stockbridge dampers;
Arrange two parallel groove clamps in wire clamp bilateral symmetry, aerial condutor and metallic cable are fixed together by each parallel groove clamp side by side.
Advantage of the present utility model: the generation being avoided stockbridge damper positioning phenomenon by the fixing of this device and restriction, the shockproof effect maintaining stockbridge damper reduces maintenance difficulty, alleviates labour intensity, ensures the safe operation of transmission line; This device is succinctly easy for installation, and solid and reliable maintenance is convenient, with low cost suitable for large-scale promotion.
Accompanying drawing explanation
Fig. 1 adopts the mounting structure schematic diagram preventing stockbridge damper positioning device from fixing stockbridge damper described in the utility model;
Fig. 2 is the link structural representation preventing stockbridge damper positioning device from fixing stockbridge damper described in the utility model;
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Embodiment one: present embodiment is described below in conjunction with Fig. 1 to Fig. 3, one described in present embodiment prevents stockbridge damper positioning device, and aerial condutor 3 is provided with insulator by wire clamp 1, arranges two stockbridge dampers 4 in the bilateral symmetry of wire clamp 1,
The described stockbridge damper positioning device that prevents comprises two parallel groove clamps, 2, two stockbridge damper fastening bolts, 5, two annulus binding posts 6 and metallic cable 7,
The two ends of metallic cable 7 are provided with an annulus binding post 6, are fastened on two stockbridge dampers 4 by annulus binding post 6 by stockbridge damper fastening bolt 5, and then are fixed on by metallic cable 7 between two stockbridge dampers 4;
Arrange two parallel groove clamps 2 in wire clamp 1 bilateral symmetry, aerial condutor 3 and metallic cable 7 are fixed together by each parallel groove clamp 2 side by side.
The diameter of stockbridge damper fastening bolt 5 matches with the size of annulus binding post 6 connecting hole.
The length of metallic cable 7 is the distance between two stockbridge dampers 4 of wire clamp 1 both sides.
Annulus binding post 6 is fixed on the two ends of metallic cable 7, annulus binding post 6 is fastened on the metallic cable 7 of annulus binding post 6 effect wire clamp both sides stockbridge damper 4 played and is connected and fixed wire both sides stockbridge damper 4 by two ends by stockbridge damper fastening bolt 5, parallel groove clamp 2 is used for metallic cable 7 to be fixed on aerial condutor 3, plays the effect fixing this device.According to the size of size determination annulus binding post 6 connecting hole of stockbridge damper fastening bolt 5.The length of the distance determination metallic cable 7 after correctly installing by regulatory requirements according to wire clamp 1 both sides stockbridge damper 4 between two stockbridge dampers 4.
The consistency and elasticity of metallic cable 7 meets installation requirement and plays the effect of fixing stockbridge damper 4, and the length of stockbridge damper fastening bolt 5 meets the technological standards requirement after connecting annulus binding post 6.
By this device by the fixing of wire clamp 1 both sides stockbridge damper 4 with is connected serve to stockbridge damper 4 fix and restriction avoid stockbridge damper 4 positioning phenomenon generation and, the shockproof effect maintaining stockbridge damper 4 reduces maintenance difficulty, alleviate labour intensity, ensure the safe operation of transmission line.
