Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model 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.
