Abstract

The invention discloses a self-supplementing liquid-state back-flushing arc extinguishing device, and belongs to the technical field of lightning protection arc extinguishing. The self-supplementing liquid-state back-flushing arc extinguishing device comprises a back-flushing pipe, an automatic liquid supplementing bin and a liquid storage box; the back-flushing pipe is vertically and downwards arranged in an inverted mode, the bottom of the automatic liquid supplementing bin and the back-flushing pipe are arranged in a sealed mode, and the liquid storage box is arranged at the upper end of the automatic liquid supplementing bin and arranged in a sealed mode; a small plastic ball and liquid are placed in the liquid storage box, the small plastic ball sinks to the bottom of the liquid, the small plastic ball is arranged at the bottom in the back-flushing pipe to block the nozzle, and the liquid is stored in the back-flushing pipe. The arc extinguishing pressure of the cut-off arc reaches 100 barometric pressures, the recoil pressure is helped to act on the impact arc and cut off the impact arc, an arc building channel is cut off, the reignition of the impact arc is delayed, and the lasting and huge recoil pressure destroys the continuous discharge condition and the reignition condition.

Description

technical field [0001] The invention relates to the technical field of lightning protection and arc extinguishing, in particular to a self-supplementing liquid recoil arc extinguishing 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 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. [0003] The single recoil arc extinguishing device can effectively reduce the lightning current and make the v...
