Abstract

The invention discloses a novel combined arc extinguishing lightning protection device, and belongs to the technical field of lightning protection and arc extinguishing, the novel combined arc extinguishing lightning protection device comprises an end portion arc extinguishing unit, a sealing arc extinguishing unit and an insulator chain, the sealing arc extinguishing unit is arranged on the insulator chain in parallel, and the end portion arc extinguishing unit is arranged at the upper end or the lower end of the insulator chain and is electrically connected with an insulator chain end portion metal piece. When the end portion arc extinguishing unit is arranged at the upper end of the insulator string, the bottom of the insulator string is grounded, and when the end portion arc extinguishing unit is arranged at the bottom of the insulator string, the bottom of the end portion arc extinguishing unit is grounded. The arc extinguishing integrality is high, reignition is avoided, the arc is integrally cut off at the same time instead of being cut off in sections, and the medium recovery speed tends to be infinite and reaches the limit of itself, so that the arc extinguishing speed is high, and the reignition is avoided.

Description

technical field

[0001] The invention relates to the field, in particular to a novel combined arc extinguishing and lightning protection device. Background technique

[0002] Lightning strikes will bring different forms of damage and destruction to power facilities, and thundercloud discharge will cause lightning strike overvoltage in the power system. Lightning strike overvoltage may cause damage to insulators and transmission lines; the impact flashover caused by lightning strikes on transmission lines will cause flashover of line insulators, and then generate a large power frequency current, damage insulator strings and fittings, and cause line accidents; Electric shock on the transmission line or lightning protection line may cause broken strands or even rupture, making the transmission work impossible.

[0003] The existing lightning protection and arc extinguishing device can make the volt-second characteristics of the active arc extinguishing parallel gap more flat, b...
