摘要

The invention relates to the field of power industry, and in particular, to the means of lightning protection of high-voltage overhead power lines (VL).; Technical result of utility model - increase the reliability and manufacturability of lightning protection of overhead line.; The apparatus comprises a non-linear resistor (1) formed as a varistor column, enclosed in an insulating housing, and a supporting insulator (2). The resistor (1) and insulator (2) are fixed on the plate (3) anchor-corner pole of a bracket (4) at a fixed distance from each other. The external spark gap (5) formed between the first discharge electrode (6) secured to the lower flange (7) of the resistor (1) and a second discharge electrode (8) secured to the bottom flange (9) of the insulator (2). The electrode (8) formed as a metal torus elongated in the direction of the resistor (1).; The dimensions of the spark gap (5), the electrode (8) and the electrical parameters of the nonlinear resistor jointly satisfy the relations given in the description.; Overhead, the proposed device provided with lightning protection, has a substantially lower probability of lightning blackouts when passing overhead in areas with bad conductive primers. 2 n.p.f. 2 z.p.f. 1 yl.
