Arrester, high-voltage insulators with dischargers and high-voltage power lines, use this INSULATOR

摘要

Presented gap for lightning protection of electrical components or transmission lines, comprising an insulating body and multielektrodnuyu system consisting of at least five electrodes disposed within the insulating body with the possibility of forming, under the influence of a lightning overvoltage, an electric discharge between adjacent electrodes, wherein between adjacent electrodes formed on the surface facing the insulating body discharge chambers. At least a part of the electrodes has a cylinder shape, and their end surfaces, at least in part - the shape of the second-order surface.; Also described high-voltage insulator comprising said arrester, high-voltage power line and using the insulator. 3 n.p.f. 8 z.p.f. 4 yl.
