Problems solved by technology

The reason why the traditional lightning rod currently in use is made into a spire and placed at a high place is to make it easier to discharge and get closer to the cloud layer, but it essentially responds passively to changes in the electric field of the thundercloud, that is, passively induces lightning. , without the function of discharging in advance, which may easily cause faults such as lightning tripping of high-voltage substations

Abstract

The invention relates to the technical field of lightning protection equipment, in particular to a predischarge lightning conductor. The predischarge lightning conductor comprises an air-terminal body (1), a downlead, a supporting rod (2) and a substrate (3), wherein the air-terminal body (1) is fixedly connected with one end of the downlead; the other end of the downlead is connected with the substrate (3); the substrate (3) is grounded; the downlead is arranged in the supporting rod (2); a lightning conductor cover (4) is arranged at the upper part of the supporting rod (2); a solar absorption board (5) is mounted on the outer surface of the lightning conductor cover (4); a storage battery (6) and a predischarge induction device (7) are internally arranged in the lightning conductor cover (4); and the predischarge induction device (7) is connected with the conductor cover (4) and the downlead in a circuit mannner. Compared with the prior art, the predischarge lightning conductor is novel and simple in structure; a predischarge function is achieved; protection radius is larger; lightning current pulse intensity in each air terminating is reduced; and a secondary effect caused by lightning induction is reduced.

Description

[technical field] [0001] The invention relates to the technical field of lightning protection equipment, in particular to a pre-discharge lightning rod. [Background technique] [0002] Lightning is a phenomenon of violent discharge of charged clouds to ground buildings and the ground. Strong lightning currents can cause serious damage to buildings and equipment. Therefore, lightning rods are widely used in petrochemical warehouses, radio and television, gas stations, building buildings, beacon stations, communication base stations, meteorological stations, military bases, radar rooms, bank buildings and other high-rise buildings. A lightning protection device composed of lightning-termination body, down-conductor and grounding device, in which the lightning-termination body is installed on the frame and higher than the object to be protected, and is used to intercept lightning strikes so that it does not fall on objects within the protection range of the lightning rod. And ...
