Description
Technical field
The invention belongs to electrical power distribution line facility related fieldss, and in particular to it is a kind of can prevent insulated overhead line by
Lightning-caused breaking guarantees the lightning-proof composite insulator of overhead insulating power distribution network safety.
Background technique
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, so that 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.
Widely apply insulated conductor on domestic high-tension line now, but the resistance to Lei Shuiping of insulated conductor inadequate natural endowment
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 insulating from leading at present
The measure that line lightning-caused breaking is taken has: setting up overhead ground wire, installation Zinc-Oxide Arrester etc., but has the disadvantage in that throwing
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 it needs to customize different high-tension lines according to different places to use and prevents
Thunder support insulator, this is undoubtedly uneconomic.
Summary of the invention
It is an object of the invention to solve the problems of the prior art, provide it is a kind of design rationally, it is safe and reliable
Lightning-proof composite insulator.
In order to realize the technical problems to be solved by the invention, using following technical scheme: a kind of lightning-proof composite insulator,
Including insulating protective cover, clamp fitting, parachute skirt, steel feet, insulation mandrel, cross-arm, draw fox stick, gap ball one, gap ball two；
The clamp fitting includes fixed torque nut, upper clamp fitting, tension seat, and fixed torque nut is upper and lower integral structure, in
Between be equipped with groove, the inside of fixed torque nut upper half part is the non-threaded setting of circular hole, fixed torque nut lower portion
Inside is set as internal screw thread, and fixed torque nut is matched with screw rod；It is set on the tension seat there are two screw rod, fixed torsion spiral shell
Mother connects tension seat together with upper clamp fitting；The tension seat, parachute skirt, steel feet successively connect on insulation mandrel；It is described
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 feet bolt are successively arranged below the steel feet；
The outside of clamp fitting is arranged in the insulating protective cover.
It when the power transmission line in clamp fitting needs to clamp, turns fixed torque nut top and is fastened, when reaching one
When determining torsion, fixed torque nut top is broken apart with lower part, to keep power suffered by power transmission line on clamp fitting 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 the effect that fox stick is drawn in certain insulation and protection.
The utility model has the advantages that the configuration of the present invention is simple, design are reasonable, safe and reliable, due to being existed using fixed torque nut
Power transmission line is protected when the installation of equipment, while being provided with insulation starting rod and gap ball again, after clamp fitting in lightning stroke,
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 and be struck by lightning
Bad striking body, no replacement is required a whole set of products are saved expense, are brought convenience to line upkeep, save trouble and labor.
