Abstract
The utility model relates to a lightning protection column type composite insulator which overcomes the poor security performance of the conventional lightning protection column type composite insulator that affects the service lifetime. The lightning protection column type composite insulator comprises an insulation core rod, a silicone rubber umbrella skirt, and a sheath, wherein the silicone rubber umbrella skirt is located at the periphery of the sheath; the insulation core rod is arranged inside the sheath; two ends of the sheath are each provided with a connecting piece; and an insulating layer is arranged between the sheath and the insulation core rod. An insulating layer is arranged between the sheath and the insulation core rod in the insulator, thereby improving the insulating performance, providing protection, and prolonging the service lifetime.
Description
Technical field
The utility model relates to a kind of insulator, refers in particular to a kind of lightning protection post composite insulators.
Background technology
The 10kV suspended insulated guide wire had both had the effect of common pin insulator support wire and insulation with FLZJ50-300 (A/B) type puncture lightning protection post composite insulators; Has again the defencive function that prevents lightning-caused breaking.Be applicable to the power station facility, have good hydrophobicity, ageing resistance, proof tracking and electrical erosion resistance have very high bending strength, and its shock resistance, shockproof and anti-fragility can be good, lightweight, easy for installation.During installation, wire need not divest insulated hull, and easy construction is reliable, has alleviated greatly again operator's labour intensity simultaneously.The lightning protection principle of lightning protection column type porcelain insulator is: insulated conductor is fixed between the pressing plate and high voltage piercing electrode of lightning protection pillar insulator.In the time of lightning strikes; when lightning overvoltage surpasses certain numerical value; cause flashover between the arc guide rod of lightning protection pillar insulator and grounding electrode-extinguishing arc cap; form short-channel; the power frequency arc that continues just burns between arc guide rod and extinguishing arc cap; protect insulated conductor to avoid being burnt, thereby also just avoided the generation of the anti-lightning strike broken string accident of insulated conductor.Existing lightning protection pillar insulator exists the striking weak effect can not realize effective lightning protection, thereby affects the serviceability of insulator.Existing its plug of lightning protection post composite insulators and sheath fit, and therefore can not effectively realize insulation effect, cause lightning protection properties to reduce.
Summary of the invention
In order to overcome deficiency and the defective in background technology, the utility model provides a kind of lightning protection post composite insulators, solves existing lightning protection post composite insulators and exists security performance relatively poor, thereby affect the problem in useful life.
The technical solution of the utility model is: a kind of lightning protection post composite insulators, comprise insulation mandrel, silicon rubber full skirt and sheath, described silicon rubber full skirt is positioned at the sheath periphery, described insulation mandrel is located in sheath, the two ends of described sheath are respectively equipped with connector, the insulating barrier that is provided with between described sheath and insulation mandrel.
Described insulating barrier is made by glass fiber material.
Described insulation mandrel is the epoxy resin fiberglass material.
The beneficial effects of the utility model: the insulating barrier because this insulator is provided with between sheath and insulation mandrel, improve insulation property, play the effect of protection, improve useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, insulation mandrel 1, silicon rubber full skirt 2, sheath 3, connector 4, insulating barrier 5.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
As shown in the figure, a kind of lightning protection post composite insulators, comprise insulation mandrel 1, silicon rubber full skirt 2 and sheath 3, described silicon rubber full skirt 2 is positioned at sheath 3 peripheries, described insulation mandrel 1 is located in sheath 3, the two ends of described sheath 3 are respectively equipped with connector 4, the insulating barrier 5 that is provided with between described sheath 3 and insulation mandrel 1.According to such scheme, the insulating barrier because this insulator is provided with between sheath and insulation mandrel improves insulation property, plays the effect of protection, improves useful life
In the utility model, described insulating barrier 5 is made by glass fiber material.It is high that the glass fibre glass fibre has heatproof, anti-corruption, the advantage such as heat insulation, that tensile strength is high, and electrical insulating property is good.
In the utility model, described insulation mandrel 1 is the epoxy resin fiberglass material, and epoxy resin fiberglass has the higher and good electrical insulating property of compression strength, improves lightning protection effect.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
