Abstract
The utility model relates to a lightning protection column type ceramic insulator and mainly solves a problem that service life is influenced by reduced safety performance caused by poor lightning protection performance existing in a lightning protection column type insulator in the prior art. The lightning protection column type ceramic insulator comprises a sheath, an umbrella skirt and an insulation core rod, wherein the insulation core rod is arranged in the sheath, two ends of the sheath are provided with metal tools, the insulation core rod and the sheath are integrated into one body, a lower end of the sheath is mounted with an arc striking plate, the arc striking plate extends upwards in an inclination mode along two sides of the sheath, and end portions of the arc striking plate are provided with bending portions. According to the lightning protection column type ceramic insulator, a solid column type insulator is employed, the insulation core rod and the sheath are integrated into one body, the umbrella skirt is prepared by ceramic materials, arc striking effects of the arc striking plate are exerted, so lightning protection effects can be effectively realized, and service life is improved.
Description
Technical field
The utility model relates to a kind of insulator, refers in particular to a kind of lightning protection pillar porcelain insulator.
Background technology
Lightning protection pillar porcelain insulator be by mucilage binding for good and all on metab, sometimes a kind of rigidity insulator that also has a cap or one or more insulating part to form, and availablely be installed on the supporting structure with being contained in stud on the metab or one or several bolt rigidity.Be used for nominal voltage and be higher than 1000V, frequency is not more than 100Hz, and height above sea level is no more than 1000m, common area and in, insulation and support lead usefulness in the alternating electromotive force circuit in heavy pollution area, the ambient temperature of its infield is between-40 ℃ ~+40 ℃.The lightning protection post composite insulators can replace pin insulator, pin insulator belongs to type B insulator, and puncture, the damage phenomenon of being easy to generate in service causes the toughened glass insulator breakage, in servicely easily puncture along insulator is inner, thereby influence useful life of product.
Summary of the invention
In order to overcome deficiency and the defective in the background technology, the utility model provides a kind of lightning protection pillar porcelain insulator, solves existing lightning protection pillar porcelain insulator and exists lightning protection effect relatively poor, thereby cause security performance to reduce, and impacts the product problem in useful life.
The technical solution of the utility model is: a kind of lightning protection pillar porcelain insulator, comprise sheath, full skirt and insulation mandrel, described full skirt is positioned at the sheath periphery, described insulation mandrel is located in the sheath, the two ends of described sheath are provided with gold utensil, and described insulation mandrel and sheath are wholely set and form, and the lower end of described sheath is equipped with run-on tab, described run-on tab is tilted to along the both sides of sheath and extends, and the end of described run-on tab is provided with bending part.
Described run-on tab is symmetrically distributed in the central shaft both sides of sheath.
Described bending part is arc.
Described full skirt is that ceramic material is made.
The beneficial effects of the utility model: because this lightning protection pillar porcelain insulator adopts solid pillar insulator, insulation mandrel and sheath are wholely set and form, and full skirt to be ceramic material make, and the striking effect by run-on tab, can effectively realize lightning protection effect, improve useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, insulation mandrel 1, silicon rubber full skirt 2, sheath 3, gold utensil 4, insulating barrier 5, bending part 6.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
As shown in the figure, a kind of lightning protection pillar porcelain insulator, comprise sheath 1, full skirt 2 and insulation mandrel 3, described full skirt 2 is positioned at sheath 1 periphery, and described full skirt 2 is made for ceramic material, described insulation mandrel 3 is located in the sheath 1, the two ends of described sheath 1 are provided with gold utensil 4, and described insulation mandrel 3 is wholely set with sheath 1 and forms, and the lower end of described sheath 1 is equipped with run-on tab 5, described run-on tab 5 is tilted to along the both sides of sheath 1 and extends, and the end of described run-on tab 5 is provided with bending part 6.According to such scheme, because this lightning protection pillar porcelain insulator adopts solid pillar insulator, insulation mandrel and sheath are wholely set and form, and being ceramic material, makes full skirt, and the striking effect by run-on tab, can effectively realize lightning protection effect, improve useful life.
In the utility model, described run-on tab 5 is symmetrically distributed in the central shaft both sides of sheath 1, and described bending part 6 is arc.When thunderbolt takes place the time; when lightning overvoltage surpasses certain numerical value; cause flashover leading between arc plate and the extinguishing arc cap of lightning protection pillar insulator; 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.
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.
