Problems solved by technology

[0002] Microwave tower is a kind of signal transmission tower, also called signal transmission tower or signal tower. Its main function is to support signal transmission and support signal transmission antenna. In order to prevent the microwave tower from being struck by lightning, lightning rods are usually installed on the top of the microwave towers on the ground, roofs and mountains. Although the risk of lightning strikes is reduced to a certain extent, lightning strikes still occur. The lightning rods used in existing microwave towers are usually The lightning rod (lightning receptor) invented by Franklin is used to attract the thundercloud electric field to concentrate on its metal needle to increase the electric field intensity at the needle end, so that the thundercloud electric field breaks down the metal needle and releases the strong lightning current through its grounding body. ground, but the lightning protection of the lightning rod usually brings negative hazards such as counterattack, step voltage, contact voltage, and electromagnetic pulse induced overvoltage damage to the strong and weak current system

Abstract

The invention belongs to the technical field of lightning protection, and discloses a microwave tower passive corona field lightning expelling device, which comprises a passive lightning dispeller arranged at the top of a microwave tower, wherein the passive lightning dispeller comprises a metal outer cover of which the bottom end is provided with an opening, the outer wall of the metal outer cover is uniformly provided with a plurality of discharge rods, the inner wall of the opening end of the metal outer cover is provided with an insulating support, the bottom of the insulating support is provided with an electrode, a discharge gap is arranged between the electrode and the inner wall of the metal outer cover, and the electrode is connected with a ground wire. According to the invention,based on the above structure, two-stage discharge under the action of a thundercloud electric field is realized, a passive first-stage discharge corona is generated between the discharge rod and thethundercloud, and a passive second-stage corona discharge is generated between the metal outer cover and the electrode; and a large number of corona ions are generated through the two-stage discharge,and the corona ions diffuse into the air and continuously interact with thundercloud charges, so that the downlink pilot development speed and intensity of thundercloud are effectively weakened.
