Non-lightening earthling lightning protection device and method

Abstract

The invention belongs to the technical field of lightning protection, and discloses a non-lightening earthling lightning protection device and method, which can realize lightning protection without forming a lightning stroke point in a large range. The method comprises steps: an atmospheric electric field intensity threshold value is preset; the ground atmospheric electric field intensity of a protection area is detected in real time; when the actual electric field intensity measurement value is greater than the atmospheric electric field intensity threshold value, whether thundercloud existsabove the protection area or not is determined; the risk that the thundercloud forms lightning stroke in the area is judged according to the actual measured ground atmospheric electric field intensityof the protection area; plasmas are diffused to the atmospheric space in the protection area, bidirectional charge neutralization is carried out on charges developed from the bottom of the thundercloud to the ground and charges escaping from the tip of the ground, so that the development of the charges at the bottom of the thundercloud to the ground of the protection area and the upward development of the charges escaping from the tip of the ground are inhibited, the formation of lightning stroke conditions is destroyed, and the construction of a lightning-stroke-free protection area is completed. Thus, the purpose of no lightning stroke in the protection area can be achieved, and the formation of secondary lightning stroke can be avoided.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to a lightning protection device and method for non-leading lightning into the ground. Background technique [0002] At present, the protection of direct lightning strikes at home and abroad is to lead the lightning into the ground and passive lightning protection. The metal tip is used to connect the lightning, and the lightning current is released to the soil around the protected object through the grounding body, so as to achieve direct strike. The purpose of lightning protection. [0003] A large number of engineering cases show that this lightning protection method of leading lightning into the ground not only cannot protect against lightning strikes, but will increase the frequency of lightning strikes near the lightning protection protection area; The lightning method will form a secondary lightning strike in the surrounding space, resulting in strong lightning ...

Problems solved by technology

[0004] Aiming at the problem that the existing method of leading lightning into the ground and receiving lightning in the passive lightning protection technology tends to cause high frequency of lightning strikes and easy formation of secondary lightning strikes, the present invention must provide a protection device and method for direct lightning strikes, with non-destructive The principle of lightning induction and the active lightning protection method destroy the formation of the discharge channel between the cloud and the ground, realize the formation of no lightning strike points in the lightning protection protection area, and avoid secondary disasters caused by induction lightning in the protection area, which can effectively solve the problems in the background technology.
