Problems solved by technology

The existing parallel gap lightning protection device for overhead line insulator strings has the following main disadvantages: ① The parallel gap lightning protection device is only suitable for 110KV and 220KV overhead line lightning protection, and is not suitable for power distribution at and below 35KV ② The electrodes on both sides of the parallel gap are fixed structures, which cannot automatically adjust the size of the gap to dredge the power frequency arc as soon as possible

Abstract

The invention provides a parallel gap lightning protector with an oscillating arm electrode, belongs to the technical field of the lightning protection of power overhead lines, and in particularly relates to an annular parallel gap lightning protector with the oscillating arm electrode and a high-voltage overhead line insulator string; the annular parallel gap lightning protector is capable of automatically rotating according to the short circuit condition of power-frequency electric arcs, and therefore, the length of the gap is increased to extinguish the power-frequency electric arcs as soon as possible, and lightning stroke line breakage accidents are effectively reduced; the following technical scheme is adopted: a current guide ring is a conducting metal ring which closely sleeves a naked conductor obtained by peeling off an insulating layer of a lead, a lead side electrode and a ground side electrode both are spherical rod-like electrodes, one ends of the lead side electrode and the ground side electrode both are made of spherical metal relatively high in density, the other end of the lead side electrode is fixedly connected with the current guide ring, a rotating disc is arranged on the other end of the ground side electrode and hinged with one end of a fixed support, the other end of the fixed support is fixed on the lower end of an insulator, and a self-oscillating device is further mounted in the middle of the fixed support.

Description

technical field [0001] The invention relates to a parallel gap lightning protection device with swingable arm electrodes, which belongs to the technical field of lightning protection protection for electric power overhead lines, and in particular relates to a lightning protection device for electric power overhead lines of 35KV and below. Background technique [0002] Transmission line faults caused by lightning strikes are one of the main fault types of overhead transmission lines, which often cause huge economic losses and adverse social impacts. The lightning protection work of overhead transmission lines has undergone continuous research and exploration. Although some achievements have been made, the faults caused by lightning strikes still account for a large proportion of the power grid. For the distribution network of 35KV and below, due to the complex structure of the distribution network and the low design insulation level, once the distribution lines located in the...
