Problems solved by technology

[0006] The dissipative array (DAS) generates plasma under the action of the thundercloud electric field to neutralize the thundercloud charge. Due to the self-assessment avoidance effect, the plasma generated is far from sufficient for lightning elimination, resulting in a high probability of failure in lightning elimination, especially through Semiconductor lightning suppressors with insufficient flow are often destroyed by lightning

Abstract

The invention relates to a passive plasma lightning expeller. The passive plasma lightning expeller comprises a metal outer cover, wherein a plurality of discharge needles are uniformly arranged at the outer wall of the metal outer cover; an insulator is arranged at the inner wall of the opening end of the metal outer cover, an electrode is arranged at the bottom part of the insulator, a separating device is arranged between the electrode and the inner wall of the metal outer cover, and the electrode is connected with ground through a grounding line. The passive plasma lightning expeller has the advantages that by arranging the metal outer cover, the discharge needles, primary discharge needles and the electrode, under the action of a lightning cloud electric field, the primary discharge needles and the lightning cloud can produce passive primary discharge, and the metal outer cover and the electrode produce passive secondary discharge, so that a large amount of plasmas is produced by two stages of discharge; positive ions drift to the lightning cloud, the negative charges in the lightning cloud are neutralized, and then the lightning cloud is weakened, so as to protect buildings.

Description

[0001] Technical field: [0002] The invention relates to the technical field of lightning protection, in particular to a passive plasma lightning drive. [0003] Background technique: [0004] For more than 260 years, the international lightning protection community has mainly used the lightning rod (lightning receptor) invented by Franklin, which attracts the thundercloud electric field to concentrate on its metal needle and increases the electric field intensity at the needle end, so that the thundercloud electric field breaks down the metal needle and will be strong. The lightning current leaks into the ground through its grounding body, which brings negative hazards such as counterattack, step voltage, connection voltage, and electromagnetic pulse induced overvoltage damage to the strong and weak current system. [0005] The early discharge lightning arrester (ESE) of the same lightning receiving mechanism attracts more lightning side strikes and shielding strikes, which i...
