Abstract
The utility model relates to an antifouling lightning arrester of metal oxide, comprising a porcelain sleeve, umbrella skirts, etc., wherein, the diameter of the umbrella skirts is respectively arranged as 80-84 mm and 101-105 mm; the vertical distance between the umbrella skirts is respectively arranged as 22-26 mm and 42-46 mm. Because the diameter of the umbrella skirt is increased, the vertical distance between the umbrella skirt is lengthened, preventing the water column state formed when sewage flows upward to cause the sewage to form small drops to drop, and avoiding that the surface of the lightning arrester discharges electricity to ground.
Description
The utility model relates to a kind of lightning arrester, specifically a kind of 10KV anti-fouling type metal oxide arrester.
At present, the designed creepage distance of existing 10KV metal oxide arrester insulator generally is 290mm, lightning arrester full skirt 7-8 sheet, and the vertical range between the full skirt is shorter, is generally about 20mm.When meeting rain, snow weather, rainwater, snow-broth mix with impurity such as dust in air, on the full skirt face of lightning arrester, form sewage and mobile, because close together between the full skirt, sewage will form the water column state when the trickling downwards of full skirt surface, cause the lightning arrester surface creepage apart from shortening, thereby form discharge over the ground.
The utility model promptly is to provide a kind of anti-fouling type metal oxide arrester at above-mentioned the deficiencies in the prior art.
The purpose of this utility model realizes like this:
A kind of anti-fouling type metal oxide arrester comprises lightning arrester insulator, full skirt, it is characterized in that the diameter of lightning arrester 1,3,5,7 full skirts is set to 101mm-105mm, and the diameter of 2,4,6 full skirts is 80mm-84mm; 1, the vertical range between 3,5,7 full skirts is set to 42mm-46mm, and the air line distance of full skirt 1,3,5,7 and full skirt 2,4,6 is set to 18mm-22mm, and the vertical range between full skirt 2,4,6 and the full skirt 3,5,7 is set to 22mm-26mm.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
As shown in the figure, under the situation that does not increase former lightning arrester insulator height, by testing repeatedly, comparing, the diameter of full skirt 1,3,5,7 is set to 103mm at last, the diameter of full skirt 2,4,6 is set to 82mm, and the vertical range between the full skirt 1,3,5,7 is set to 44mm, and the air line distance between full skirt 1,3,5,7 and the full skirt 2,4,6 is set to 20mm, vertical range is set to 24mm, and the creepage distance of lightning arrester insulator design is set to 350mm.
Because the full skirt diameter is apart from lengthening, strengthen with vertical range between the diameter full skirt, thereby formed water column state when having prevented effectively that sewage from flowing downward on the full skirt surface forms the globule drippage when sewage is flowed downward, thereby has avoided the discharge over the ground on lightning arrester surface.
