Strut type porcelain insulator for saline-alkali heavy pollution of oil field

Abstract

The invention discloses an oil field saline-alkali heavy pollution pillar type porcelain insulator which comprises a lower fixing piece and an upper fixing piece, an insulating core is arranged between the lower fixing piece and the upper fixing piece, and the insulating core comprises an insulating column, a plurality of large umbrella skirts and a plurality of small umbrella skirts. The large umbrella skirts and the small umbrella skirts are evenly arranged in the outer circumferential direction of the insulation column in a staggered mode, a ceramic cap is arranged above the insulation column, the upper end of the ceramic cap is connected with an upper fixing piece, the upper end of the insulation column extends into the ceramic cap to be fixedly connected, and the lower end of the insulation column is fixedly connected with a lower fixing piece. The insulating cap is of a hemispherical structure, and the cross section area of the insulating cap is larger than that of the large umbrella skirt and the small umbrella skirt. Compared with the prior art, the porcelain insulator has the advantages that the structure is simple, and the dry protection creepage distance and the wet withstand voltage performance of the porcelain insulator are obviously improved; the problem that flashover fault power failure occurs in the oil field saline-alkali soil in spring and autumn rainy days, and oil extraction production is affected is solved, and the effect is reliable.

Description

technical field [0001] The invention relates to the field of oil well equipment in oil fields, in particular to a pillar type porcelain insulator with heavy pollution from salt and alkali in oil fields. Background technique [0002] The operation of oil well equipment in the oil field ensures normal power supply is the first step in oil production and production. The ordinary pillar porcelain bottle used in the 35kV power station in the salt-alkali heavily polluted area runs in the spring and autumn drizzle. Frequent flashovers lead to power outages, which affect a large number of oil wells and stop production. Therefore, in the common pillars Insulation links must be added to the porcelain bottle. The salt-alkali heavy-dirty porcelain bottle should have the performance of high humidity and flashover voltage resistance while ensuring the withstand voltage. At present, it is basically solved by superimposing one more insulator of the same type. Obvious disadvantages: [0003...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the use of ordinary pillar porcelain vases, the humidity is high in spring and autumn drizzle, and the protection creepage cannot guarantee dryness, resulting in flashover and power failure;

[0004] 2. In the saline-alkali heavily polluted area of ​​the oil field, ordinary pillar porcelain bottles are discharged in case of filthy and wet surfaces in drizzle, and the insulators need to be cleaned frequently. Frequent cleaning will cause power outages and shutdowns, affecting oil production;

[0005] 3. Due to the heavy saline-alkali pollution area of ​​the oil field, the humidity is high in the spring and autumn drizzle, the surface of the ordinary pillar porcelain bottle flashes over, and the power failure occurs, which seriously affects the oil production and causes great economic losses.
