A kind of compound anti-bias wind insulator
The present invention relates to insulator technology fields, more particularly to a kind of compound anti-bias wind insulator.
In high voltage power transmission and transforming circuit, windage yaw ground connection electric discharge is always to influence one of the problem of line security is run.Insulation
Sub- windage yaw ground connection refers to that suspension insulator deviates upright position under windy conditions and deviated to steel tower tower body certain phase line is caused to connect
Ground, such accident is in recent years a lot of in the generation of 110kV Above Transmission Lines, seriously affects and threaten the safe operation of network system.In order to
Prevent windage yaw from discharging, all fixed wind-deviation insulator, is used to support the transition of wire jumper section on shaft tower, is installed in insulator lower end
Weight, and external cable is fixed by installing wire clamp, it is this although to produce one using weight to improve insulator chain windage yaw
Point effect, but the windage yaw of insulator cannot be really controlled under severe conditions；In addition external cable is fixed using wire clamp, is passed through
Frequent vibration is even waved, and external cable is easily worn by wire clamp, and since the heavier machinery to insulator of the weight ratio of weight is strong
Degree also improves very high requirement, virtually increases many costs.
The present invention cannot really control the technologies such as the windage yaw of insulator under severe conditions for existing wind-deviation insulator
Problem provides a kind of compound anti-bias wind insulator.
The purpose of the present invention is to provide a kind of compound anti-bias wind insulators, to solve the above technical problems.
The present invention using following technical scheme in order to solve the above technical problems, realized：
A kind of compound anti-bias wind insulator, including holder are connect by bolt with the first composite insulator on the holder；
First composite insulator includes the first gold utensil, the first silicon rubber umbrella, the first expoxy glass plug；Described first is compound exhausted
The lower end of edge is connect by bolt with the second gold utensil, the second composite insulator, the second composite insulator upper end by bolt with
Holder connects；Turntable is connected by shaft on second gold utensil, further includes the second perforation on the second gold utensil；The turntable includes
First perforation and flabellum；The conducting wire is fixed on turntable by wire clamp and across the first perforation and the second perforation.
In actual use, triangle rock-steady structure between the first insulator, the second insulator and holder can play very well
Supporting role, conducting wire across first be punched through wire clamp fix turntable on be then passed through the second perforation, under the action of the wind, turntable
Flabellum can rotate to drive conducting wire to rotate, tense the conducting wire at hard wire jumper, prevent conducting wire from generating wind under external force
Preferably, second composite insulator includes third gold utensil, the second silicon rubber umbrella, the second expoxy glass core
Preferably, first silicon rubber umbrella and the second silicon rubber umbrella are small antifouling by four big antifouling umbrella and four
Umbrella forms, and prevents raindrop bunchiness.
Preferably, first perforation and second is perforated apart from shaft apart from equal.
Preferably, it is set on second gold utensil there are one the limited block of protrusion, limited block can hinder when wind-force is excessive
The deflection for hindering flabellum is played the role of tightening conducting wire and will not pull apart conducting wire.
Preferably, it is arranged with rubber washer in the first perforation and the second perforation, it can be to avoid the hard of conducting wire and metal parts
Contact and damage the insulated part of conducting wire.
The present invention provides a kind of compound anti-bias wind insulator, advantage is：Absolutely using the first insulator, second
Triangle rock-steady structure between edge and holder, can play good supporting role, and conducting wire is punched through wire clamp across first
On fixed turntable and across the second perforation, under the action of the wind, turntable can drive circuit to rotate, and tense the conducting wire at hard wire jumper,
Prevent conducting wire from generating windage yaw ground connection under external force.Apparatus of the present invention are good using wind-deviation effect, simple in structure.
