The objective of the invention is to be achieved through the following technical solutions:
A kind of lightning protection pillar insulator comprises that an insulating shield and is arranged at the clamp gold utensil that is made of upper holder block and lower lock block of this insulating shield inside, also comprises a starting rod that is connected with this clamp gold utensil side; The insulator that one two ends are connected with cross-arm with this clamp gold utensil lower end respectively; Be arranged on the following steel pin of close cross-arm one end in this insulator;
Wherein, the lower surface of this upper holder block and the upper surface of lower lock block are provided with some grooves, and this upper holder block is connected with two clamp nuts by two bolt inserts with lower lock block.
Wherein, be provided with the puncture ratchet in this groove.
Wherein, clamp nut is provided with jack panel fully.
Wherein, this starting rod is bending, and its other end is near this time steel pin.
Wherein, this starting rod is with an insulating sleeve outward.
Wherein, this starting rod is a hemisphere jut near an end of this time steel pin.
Wherein, this time steel pin is provided with a jag near a side of this starting rod.
Positive progressive effect of the present invention is:
A kind of lightning protection pillar insulator realizes that post insulator and arc-preventing metal utensil unite two into one, and has insulation and supports lead, preventing arc, simplification circuit, reduction cost and the reusable characteristics of energy; And insulator employing composite material, good insulation preformance, creepage distance is big, has improved anti-filthy level; Insulating shield adopts silastic material simultaneously, good insulation preformance, and anti-aging, fire resistance is good.

Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
Shown in Fig. 1,2,4,5,6,7 and 8, a kind of lightning protection pillar insulator, it comprises that an insulating shield 1, is arranged at the clamp gold utensil 2 that is made of upper holder block 21 and lower lock block 22 of this insulating shield 1 inside, starting rod 3 that these clamp gold utensil 2 sides are connected, two ends and is arranged in this insulator 4 following steel pin 5 near these cross-arm 6 one ends with insulator 4, that these clamp gold utensil 2 lower ends are connected with cross-arm 6 respectively.Be equal to conventional method, the starting rod 3 best outsides towards cross-arm 6.When thunderbolt takes place, cause the flashover discharge between starting rod 3 and the following steel pin 5, form short-channel, lasting power frequency arc moves to burning between starting rod 3 and the steel pin 5, avoids burn with guardwire.Insulator 4 wherein plays pillar, insulation and the antifouling effect of supporting lead 9 simultaneously.
Wherein, these upper holder block 21 lower surfaces and lower lock block 22 upper surfaces are provided with some grooves 27,28, can be provided with puncture ratchet 26 on it as required; When being provided with puncture ratchet 26, the insulating barrier that need not divest lead 9 can be realized the puncture energising, avoids core water inlet and corrosion, makes things convenient for installation; When being provided with puncture ratchet 26, lead 9 divests insulating barrier and can switch on.
Further, above-mentioned ratchet 23 adopts copper products, and the surface is through electroplating or plating is handled, prevent copper aluminium in conjunction with the time oxidation.
