Multistage ionization charge-eliminating lightning protection device

Abstract

The invention relates to a multistage ionization charge-eliminating lightning protection device, which comprises a thundercloud bottom charge gathering unit, a multistage ionization processing unit and a ground anisotropic charge gathering unit. The thundercloud bottom charge gathering unit comprises a thundercloud charge gathering net pin tray, charge gathering metal pins and a charge fixing and conducting rod. The charge gathering metal pins are fixedly installed on the thundercloud charge gathering net pin tray, and the lower part of the thundercloud charge gathering net pin tray is fixed to the charge fixing and conducting rod. The multistage ionization processing unit comprises at least two layers of ionization pole plates and an insulating layer therebetween, and the topmost ionization pole plate is fixedly installed at the lower end of the conducting rod of the thundercloud bottom charge gathering unit. The ground anisotropic charge gathering unit comprises a ground anisotropic charge gathering net pin tray and charge gathering metal pins, wherein the ground anisotropic charge gathering net pin tray is fixedly installed together with the lowermost ionization pole plate of the multistage ionization processing unit, and the charge gathering metal pins are fixedly installed on the lower surface of the ground anisotropic charge gathering net pin tray. The multistage ionization charge-eliminating lightning protection device has a good charge gathering effect, a stable and firm structure and low cost.

Description

technical field [0001] The invention belongs to the technical field of lightning protection, in particular to a multi-stage ionization and charge elimination lightning protection device. Background technique [0002] At present, in the field of direct lightning protection at home and abroad, the theory of "leading lightning currents into the ground" invented by American scientist Franklin in 1752 has been carried out on the basis of the theory. The lightning protection device is designed and installed according to the shape, category, and use properties of a certain protected object, and the lightning current is attracted to the lightning protection device and introduced into the earth, so as to realize the lightning protection of the protected object. [0003] In recent years, it has appeared in China that by gathering the charge energy at the bottom of the thundercloud, the air is discharged between the upper and lower plates, and ions with positive and negative charges ar...

AI Technical Summary

Problems solved by technology

According to the simulation calculation of the local electric field strength of this structure, the local electric field strength of the highest needle is much higher than that of other metal inclined needles, so its focusing effect is not good.

In addition, there are problems with the firmness of the multiple single-armed metal inclined needles, and the consequences are unpredictable once they are detached!

[0007] (2) The discharge effect is not good

[0012] Third, the cost is high, which is not conducive to the popularization of the application market
