Abstract
The utility model provides a serial yoke plate for 1150-kilovolt compact type 12-bundle leads, which is formed by combining an upper yoke plate, a lower yoke plate and double parallel hanging plates together by bolts, wherein the upper yoke plate and the lower yoke plate are provided with parallel hanging plate connecting holes and 12 pendant connecting holes. The upper yoke plate and the lower yoke plate are integral plates, and the double parallel hanging plates are fixed in between by the bolts, therefore, the weight of the integral plates is reduced, when the product is used in an area with heavier wind, with swinging of the leads, the structure has enough space for suspension clamps swinging for 30 degrees at the left side and right side of the parallel hanging plates, thus avoiding damaging the product caused by instantaneous higher torsional force generated by the suspension clamps or the yoke plates when the moving area is not enough. Simultaneously, the double parallel hanging plates are adopted, thus being capable of distributing the stress uniformly, preventing certain end from being highly stressed for long time, and avoiding fracture due to the fatigue strength of material. The 12 pendant connecting holes are processed by milling both sides of the yoke plates, thus being capable of meeting the requirement on connection of suspension hanging plates of any tonnage.
Description
Technical field
The utility model relates to a kind of 1150KV compact ten binary fission lead string yoke plates, belongs to the UHV transmission line field.
Background technology
At present, UHV TRANSMISSION LINES IN CHINA network voltage grade is ± 800KV, exchange 1000KV, along with national economy and science and technology development, develops the more electric power transmission network of voltage levels, can better service in society.Yoke plate be transmission line dangle the string in vitals, mainly bear the wind-force of weight, icing weight and the horizontal direction of vertical direction lead.Lead is connected with yoke plate by suspension clamp, guarantees its division radical and spacing by yoke plate.
Traditional UHV transmission line engineering lead string is generally six divisions, eight divisions with yoke plate, and great majority be that whole yoke plate, single-piece weight are bigger, and some hangers connection hole employing steel bushing welds.This version at first can not satisfy the above requirement of eight bundle conductors, and secondly construction and installation and transportation bring very inconvenience, once more, for the lower product of indivedual welding qualities, when discontinuity, very likely produce the commissure rupture failure, cause power grid accident.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of 1150KV compact ten binary fission lead string yoke plates are provided, construction and installation and convenient transportation, and intensity height and single-piece weight are little.
The technical solution of the utility model is: 1150KV compact ten binary fission lead string yoke plates, comprise upper connective plate and lower linking plate, and it is characterized in that: also comprise two parallel link plates, upper connective plate, lower linking plate and parallel link plate form through the bolt member fixed combination; Last lower linking plate all has parallel link plate connecting hole; Last lower linking plate is provided with 12 connecting holes that dangle on circumference ten halves directions, the two-sided thickness of slab processed of milling is adopted in the connection hole of dangling.
Aforesaid 1150KV compact ten binary fission lead string yoke plates, it is characterized in that: also be provided with the insulator string installing hole on the upper connective plate, lower linking plate is provided with weight sheet installing hole and weight saving hole, and the construction hoisting hole is arranged in upper connective plate or lower linking plate or upper and lower yoke plate to be had.
Aforesaid 1150KV compact ten binary fission lead string yoke plates, it is characterized in that: bolt member comprises bolt, nut and Type B closed pin.
Aforesaid 1150KV compact ten binary fission lead string yoke plates, it is characterized in that: bundle spacing is 350～450mm, breaking load is 160～1200KN.
The beneficial effects of the utility model are: the utility model extra high voltage network 1150kV compact ten binary fission lead string yoke plates, be applicable to 1150kV compact ten binary fission leads usefulness, bundle spacing is 350～450mm, and breaking load is 160～1200KN.Last lower linking plate is whole plate, the centre is two parallel link plate bolt, reduce the weight of whole plate thus, bring convenience to construction and installation and transportation, when product runs on bigger regional of wind-force, along with the swing of lead, this structure has enough spaces to make suspension clamp locate to swing 30 ° about parallel link plate, in order to avoid the zone of action when not enough, make suspension clamp or yoke plate produce bigger twisting resistance of moment, so that product destroys.Adopt two parallel link plates simultaneously, the stress of the yoke plate that can evenly distribute is unlikely to a certain end director time and is in bigger stress, avoids producing rupture failure because of the fatigue strength of material.12 hangers places adopt the two-sided thickness of slab processed of milling, and can satisfy the dangle connection of link plate of any different tonnage.
