Description
Technical field
The utility model relates generally to the inclined field of strong wind area power transmission line wind, refers in particular to a kind of adjustable type power transmission line wind deflection preventive, may be used for reducing power transmission circuit caused by windage tripping operation.
Background technology
In recent years, there is windage yaw discharge more than 300 altogether in the circuit more than 110kV belonging to State Grid Corporation of China, there are 31 windage yaw arcing faults in the 500kV transmission line that wherein National Electric Wire Netting Construction Ltd,Co. is administrative, relates to the provinces, cities and regions such as Jiangsu, Zhejiang, Anhui, Hubei, Henan, Shandong, Shanxi, Beijing, the Inner Mongol, Heilungkiang, Liaoning altogether.From above data, the windage yaw discharge rate of ultra-high-tension power transmission line seems not high, but with lightning stroke flashover and switching impulse flashover unlike, most windage yaw discharge occurs under operating voltage " due to the continuity of wind; generally can not successful reclosing after windage yaw discharge tripping operation; thus result in the stoppage in transit of circuit " operating experience shows, current windage yaw discharge rate index oneself can not meet the requirement that line security runs.
Windage yaw discharge accident is the major safety risks that electrical network normally runs, and circuit is because of reclosing not easily success after windage yaw discharge tripping operation, have a strong impact on the safe and stable operation of electric power system, thus " angle of wind deflection of insulator string and wire jumper is excessive is the immediate cause producing windage yaw discharge accident to cause great economic loss, therefore the windage yaw of high-voltage transmission line insulator string and wire jumper is subject to the extensive concern of research and engineering field, minimum air void between further investigation transmission circuit insulator string and the angle of wind deflection of wire jumper and wire to shaft tower, and the inclined flashover performance of circuit wind resistance is assessed, important practical meaning in engineering and technical economic benefit is had to the safe operation and overhead line structures design level that improve electrical network.And for working line, carrying out windage yaw " V " falsification, to make difficulty large.In order to reduce the impact of windage yaw on transmission line, particularly operating in the circuit of strong wind area, being necessary a kind of simple wind deflection preventive of design, with the inclined ability of the wind resistance improving transmission line, reducing the number of times that transmission line has a power failure because of windage yaw.
Summary of the invention
In order to solve the problem of power transmission circuit caused by windage tripping operation, the utility model is intended to design the inclined insulator of a kind of power transmission line wind, to reduce the angle of wind deflection of the insulator that transmission line causes under windage yaw effect, improve the wind-deviation ability of transmission line, reduce the probability that transmission line trips because of windage yaw.
The technical solution adopted in the utility model is:
This kind of adjustable type power transmission line wind deflection preventive forms triangle by wind-deviation insulator and shaft tower and line insulator, and it is rotatable that wind-deviation insulator is fixed on shaft tower, drives line insulator to deflect to stop wire under wind action.
Described wind-deviation insulator is made up of U bolt, fixing gold utensil, support, connecting rod and special insulation; Wherein fixing gold utensil adopts welding manner to be connected with support; Its assembly is fixed on shaft tower by U bolt by fixing gold utensil and support, is then fixed on support by connecting rod one end, and the other end connects special insulation.
The link of described connecting rod and special insulation has multiple hole, and pitch of holes is 3 ~ 10cm, and the degree of depth regulating special insulation to insert connecting rod can realize the total length of the sub-connecting rod of special insulation.
Described fixing gold utensil and support are made by stainless steel, and connecting rod can according to field condition by stainless steel tube or high strength epoxy resin pipe, and its pipe thickness is not less than 0.5cm.
The utility model is adopted to have following advantage:
1, wind-deviation insulator rotatably can not ensure that line insulator does not also rotate with the wind under wind action after circuit is connected with wind-deviation insulator.
2, because wind-deviation insulator is rotatable, when wind speed is larger, wind-deviation insulator may be stressed excessive and damage, and adopts U bolt, the multiple parts composition of fixing gold utensil, support, connecting rod and special insulation can be convenient to when damaging change.
3, connecting rod there is adjustment hole can regulate the total length of wind-deviation insulator, be convenient to in-site installation.
In sum: adjustable type power transmission line wind deflection preventive can reduce the angle of wind deflection of the insulator that transmission line causes under windage yaw effect, improve the wind-deviation ability of transmission line, reduce the probability that transmission line trips because of windage yaw.
