Abstract

The invention discloses a supercharged multistage recoil arc extinguishing method and system, which belong to the technical field of arc extinguishing and lightning protection, and are characterized in that a device for realizing the method is provided with a primary recoil device and a plurality of secondary recoil devices which are connected end to end; and the secondary recoil device at the topend is arranged at the bottom of the primary recoil device. The primary recoil device is characterized in that a lightning receiving assembly is arranged at one end of a hollow primary recoil pipe ina closed mode, a supercharged arc striking assembly is arranged at the other end of the primary recoil pipe, and each secondary recoil device comprises a secondary recoil pipe and a secondary lightning receiving electrode. The electric arc is subjected to primary supercharged recoil through the primary recoil device for the first time, so that the recoil effect is better, larger electric arcs canbe extinguished, meanwhile, sequential recoil is conducted through the multiple secondary recoil devices, and the pressure during recoil airflow jetting can be increased through the arranged sealingcover when the remaining electric arcs are extinguished.

Description

technical field [0001] The invention relates to the technical field of arc extinguishing and lightning protection, in particular to a pressurized multi-stage recoil arc extinguishing method and system. Background technique [0002] Lightning strikes can cause different forms of damage and destruction to power facilities. Thundercloud discharge can cause lightning strike overvoltage in the power system, which can be divided into direct lightning strike overvoltage and induced lightning strike overvoltage. Lightning 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 continuous 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 power transmission work impossible.
