Description

The wing card of adjustable strain insulator
Technical field
The utility model relates to single string bolt shape strain insulator string charged for replacement device on high voltage power transmission and transforming circuit, the substation bus bar, the wing card of particularly a kind of adjustable strain insulator.
Background technology
At present single string bolt shape changing strain insulator string on high voltage power transmission and transforming circuit, the substation bus bar adopts earth potential, bottle-holding rack replacing insulator under electrified, use be the wing card of monoblock type.Because the selection of insulator is mechanical strength and the creepage distance that compares that designs insulator by factors such as conductor cross-section, load, the close grade of salt ash, height above sea level, meteorological conditions, so cause a power transmission and transformation line because of the needs of economy, safety, reliability service, need to use the insulator of multiple disk track and model, generally between φ 250-420mm.Insulator string on present operating high voltage power transmission and transforming circuit, the substation bus bar, the old and new's model is used alternatingly, production firm's model differs, during operating maintenance owing to special or other reason with using insulator multi-vendor, multiple model in a string, just produced multiple disk track insulator, and the wing card of integral type can't change with using disk track insulator not of uniform size in a string.Because the wing card of monoblock type can't be adjusted to the width of be fit to installing with arm-tie according to on-the-spot insulator disk track, the bottle-holding rack link can't lifting, can not with insulator pin with is connected bowl transferring on the same axis of strain clamp.
The utility model content
The utility model purpose provides the wing card of a kind of adjustable strain insulator of the single string bolt shape strain insulator string charged for replacement that uses disk track not of uniform size on a kind of ultra-high-tension power transmission line, the substation bus bar.It can be according to the corresponding adjusting insulation of the different disk tracks of on-the-spot insulator arm-tie spacing, and make far-end operation by insulating bar, the bottle supporting frame is with the leading screw vertical lift, make the bowl head of insulator pin and connecting clamp reach same axis, make it be in best demolition, installation seat, so that smooth, quick demolition, installation insulator string.
Realization the utility model purpose is taked technical scheme: a kind of adjustable expansion resistant airfoil card, comprise front card, rear card, and respectively connect the insulation board lock device that can swing at the two ends of front card main body, in the middle of front card main body, connect two liftable front card leading screw links; Respectively connect the rear card lock device that to swing at the two ends of rear card card;
The insulation board lock device tightens together by the two ends of front card pressing plate with bolt and front card main body, insulation board lock device, front card pressing plate, front card main body three contact site all are made to zigzag, front card leading screw link upper end is combined with ratchet, ratchet is by rocking arm attended operation ring, ratchet can be locked by lock pin, and rocking arm connects together by connecting rod; Rear card lock device tightens together by the two ends of rear card pressing plate with bolt and rear card card, and rear card lock device, rear card pressing plate, rear card card three contact site also all are made to zigzag;
Two ends in front card main body connect the insulation board lock device left-right symmetry that can swing, connect the rear card lock device left-right symmetry that can swing at the two ends of rear card card, connect two liftable front card leading screw link left-right symmetry in the middle of front card main body.
Because insulation board lock device of the present utility model and rear card lock device can freely swing, and can adjust as required distance between the insulation board, block leading screw link liftable before adding, therefore can adapt to disk track replacing insulator string not of uniform size; Shorten the repair time simultaneously, increased work efficiency, reduced operation easier, improved the safety work environment.
