Description

Stockbridge damper resetting means in short distance
Technical field
The utility model relates to a kind of power distribution network power tool, is specifically related to a kind of stockbridge damper resetting means.
Background technology
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.Overhead transmission line arranges stockbridge damper and may be used for eliminating circuit self-vibration and eliminate the resonance that wind etc. causes, it is the highest that stockbridge damper is arranged on wire
Near point, after Long-Time Service, stockbridge damper may along wire slide downward, and after slip, its shockproof effect will weaken greatly.Therefore, stockbridge damper will reset by maintainer timely, to reduce or remit the generation of accident, ensures the normal power supply of electrical network.
The reset instrument of stockbridge damper of network operation personnel is varied, the cardinal principle of this kind of instrument be utilize one slidably mechanism slide on wire, pull this slide mechanism to beat stockbridge damper by staff, stockbridge damper resetted.This kind of device needs at least two people to coordinate, and slide mechanism is placed on wire in work high above the ground by a staff, and another one staff pulls slide mechanism to move in below.Its major defect is: 1. need many personnel to coordinate, and 2. operation likely produces error, stockbridge damper is resetted accurate not.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides stockbridge damper resetting means in a kind of short distance, and can reset stockbridge damper and operate simple and easy accurately.
The technical solution of the utility model realizes in the following manner: stockbridge damper resetting means in a kind of short distance, comprise insulating bar, insulating bar one end is provided with two fixed levers, fixed lever and motion bar are hinged and connected, motion bar is connected with pull bar, pull bar is connected with baffle plate, be connected by jointed shaft in the middle part of two motion bars, Compress Spring and extension spring is also connected with between two motion bars, Compress Spring is arranged between jointed shaft and insulating bar, extension spring is arranged between jointed shaft and pull bar, is also connected with stay cord bottom motion bar.
Described fixed lever is connected with sleeve, and sleeve is connected with insulating bar by screw thread.
Anti-slip rubber layer is provided with inside described pull bar.
Described insulating bar is telescopic insulation rod.
Two baffle plates are provided with projection and the groove of cooperation.
The utility model blocks the card ereisma on stockbridge damper by baffle plate and pull bar, pull insulating bar that card ereisma can be made to move on wire, and then realize the reset of stockbridge damper.Its operation is fairly simple, does not need many people to coordinate, and is easy to when operating insulating bar control displacement, makes the reset of stockbridge damper more accurate.
Accompanying drawing explanation
Be briefly described to the accompanying drawing used below, apparently, the accompanying drawing in the following describes is only examples more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is baffle arrangement schematic diagram.
Wherein: 1. insulating bar, 2. stay cord, 3. sleeve, 4. fixed lever, 5. Compress Spring, 6. motion bar, 7. extension spring, 8. pull bar, 9. jointed shaft, 10. baffle plate, 11. is protruding, 12. grooves.
Embodiment
Below in conjunction with the accompanying drawing in the utility model example, be clearly and completely described the technical scheme in the utility model example, obviously, described example is only the utility model part example, instead of whole examples.Based on the example in the utility model, those of ordinary skill in the art are not making the every other example obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in drawings, stockbridge damper resetting means in a kind of short distance, comprise insulating bar 1, insulating bar 1 one end is provided with two fixed levers 4, fixed lever 4 and motion bar 6 are hinged and connected, motion bar 6 is connected with pull bar 8, pull bar 8 is connected with baffle plate 10, be connected by jointed shaft 9 in the middle part of two motion bars 6, Compress Spring 5 and extension spring 7 is also connected with between two motion bars 6, Compress Spring 5 is arranged between jointed shaft 9 and insulating bar 1, and extension spring 7 is arranged between jointed shaft 9 and pull bar 8, is also connected with stay cord 2 bottom motion bar 6.
General stockbridge damper is primarily of cast iron tup, wire clamp clamping plate, steel strand wire, card ereisma composition, and wherein card ereisma is stuck on wire, the body shape of card ereisma is cuboid, when stockbridge damper slides time i.e. card ereisma cause along wire slip.Utility model works principle is as follows: not using state, under the acting in conjunction of Compress Spring 5 and extension spring 7, two baffle plates 10 are in contact condition, after the displacement of discovery stockbridge damper, tension stay cord 2, make baffle plate 10, pull bar 8 is in deploying device, now hand-held insulating bar 1 is by pull bar 8, baffle plate 1 is placed on card ereisma both sides, unclamp stay cord 2 afterwards, baffle plate 10, pull bar 8 is at Compress Spring 5, card ereisma is blocked under the effect of extension spring 7, now pull insulating bar 1 can realize the movement of card ereisma on wire, and then achieve the reset of stockbridge damper, after reset, again strain stay cord 2, being separated of resetting means and stockbridge damper can be realized.The utility model can realize the reset of stockbridge damper within several meters, is not suitable for stockbridge damper and offsets excessive distance.But stockbridge damper slippage several meters is just easy to be found by maintainer, therefore practical operation is very convenient.
As preferably, described fixed lever 4 is connected with sleeve 3, and sleeve 3 is connected with insulating bar 1 by screw thread.Because often use insulating bar in electric power overhaul personnel upkeep operation, insulating bar is flexibly connected with sleeve 3 by the utility model, both can be used alone insulating bar and has operated other work, also can use whole device reset stockbridge damper.Described insulating bar 1 is telescopic insulation rod, so that the operation of device, transport and preservation.
As a step is preferred again, is provided with anti-slip rubber layer inside described pull bar 8, anti-slip rubber layer is set and can better blocks card ereisma, anti-sliding stop.
As preferred further, two baffle plates 10 are provided with projection 11 and the groove 12 of cooperation.After blocking card ereisma, protruding 11 are just in time stuck in groove 12, make whole device can well drive card ereisma to move.
