Description
Technical field
The invention belongs to electrical power distribution line facility related fields, and in particular to it is a kind of can prevent insulated overhead line by
Lightning-caused breaking ensures the lightning-proof composite insulator of overhead insulating power distribution network safety.
Background technology
With global warming, lightning electricity ring meteorology is growing on and on, and lightning stroke causes the loss of electric system obvious to all, absolutely
The lightning-caused breaking of edge conducting wire occurs again and again.Conventional lightning protection pillar insulator mainly has Lightningproof composite post insulator and lightning protection porcelain
Two kinds of insulator.The housing cluster parachute of lightning-proof composite insulator using composite silicone rubber material, insulator producer be reduce at
This is easy to adulterate using poor material, while silastic material is easily pipped to influence dielectric strength by flying bird；Lightning protection porcelain
Insulator is not easy to be pipped by birds, but while being struck by lightning it is frangible fall, to which article or pedestrian can be injured by a crashing object.The present invention is using insulation
Plug covers porcelain insulator as carrier, mandrel outer, when insulator is by lightning stroke fragmentation, because internal core rod will not be broken, therefore will not
From falling from high altitude.The structure that insulation mandrel is combined with porcelain insulator, the advantages of remaining composite insulator and porcelain insulator, again
Overcome it is each its shortcomings that.
Insulated conductor is widely applied on domestic high-tension line now, but the resistance to thunder of insulated conductor inadequate natural endowment is horizontal
When by being struck by lightning, it is easy to happen lightning stroke flashover, tripping and lightning-caused breaking accident；The country prevents 10KV overhead insulatings from leading at present
The measure that line lightning-caused breaking is taken has：Overhead ground wire, installation Zinc-Oxide Arrester etc. are set up, but is had the following disadvantages：It throws
It is larger to provide cost, construction and installation are complicated, and lightning protection effect is also undesirable.Because a little high-tension line lightning protection post composite insulators are met the tendency of
And give birth to, the distance of its insulation striking body of high-tension line lightning protection pillar insulator and discharge contact currently on the market is that fixation can not
It adjusts, can not be adjusted according to environment, height above sea level；Or according to different places to use to need to customize different high-tension lines anti-
Thunder support insulator, this is undoubtedly uneconomic.
Utility model content
Utility model aims to solve the problems of the prior art, provide a kind of reasonable design, it is safe to use can
The lightning-proof composite insulator leaned on.
In order to realize technical problem to be solved in the utility model, using following technical scheme：A kind of lightning protection is compound absolutely
Edge, including insulating protective cover, clamp gold utensil, parachute skirt, steel feet, insulation mandrel, cross-arm, draw fox stick, gap ball one, gap
Ball two；The clamp gold utensil includes fixed torque nut, upper clamp gold utensil, tension seat, and fixed torque nut is one knot up and down
Structure, centre are equipped with groove, and the inside of fixed torque nut upper half part is arranged for circular hole non-threaded, fixed torque nut lower half
The inside of part is set as internal thread, and fixed torque nut is matched with screw rod；It is set on the tension seat there are two screw rod, it is fixed
Torque nut connects tension seat together with upper clamp gold utensil；The tension seat, parachute skirt, steel feet connect on insulation mandrel successively
It connects；The tension seat side, which is equipped with, draws fox stick, and gap ball one is equipped on the outside of steel feet；Cross-arm and steel are equipped with below the steel feet successively
Foot bolt；The insulating protective cover is arranged in the outside of clamp gold utensil.
When the power transmission line in clamp gold utensil needs to clamp, turns fixed torque nut top and fastened, when reaching one
When determining torsion, fixed torque nut top is broken apart with lower part, to keep the power on clamp gold utensil suffered by power transmission line uniform, is prevented
Overexertion when only turning and destroy power transmission line；The size of torsion can be realized by the depth of nut upper groove；It is different thick
The nut used on thin power transmission line can change size according to demand, while the depth of nut upper groove also changes correspondingly.
Further, the groove that fixed torque nut is vertically connected with is equipped with spacing collar, and spacing collar can be conducive to manually grasp
Accuracy when making, prevents maloperation.
Further, the starting rod is bent downward, and bottom is equipped with gap ball two, and is directed toward the gap ball one of steel feet setting,
On the same line.
Further, it is equipped with gum cover on the outside of the starting rod, plays certain insulation and the effect of fox stick is drawn in protection.
Advantageous effect：It is the utility model simple structure and reasonable design, safe and reliable, due to using fixed torsion spiral shell
Mother protects power transmission line in the installation of equipment, while being provided with insulation starting rod and gap ball again, when clamp gold utensil in lightning stroke
Later, it will pass through insulation starting rod to draw away electric current, be punched on the ball of gap, reduce the damage to composite insulator, only need to change
Expense is saved, is brought convenience to line upkeep, save trouble and labor without a whole set of products is needed to change by the bad striking body that is struck by lightning.
