Special
It is suitable for high building microwave communication station, radar base station, Beacon station, communication base station, military base, radar room, bank building, astronomical meteorological station and other important places.

 

Pre-discharge
When the ightning rod is struck by lightning, the flash is connected by the flash. Through the lightning waveform processing device, a coupling capacitor is formed by using a 3mm gap between the shell and the Central Earth rod, at the same time, when the shell passes through a inductance coil grounding (Central Earth rod) and the pilot is close to the Lightning receiver, due to the extremely high frequency, the inductance is in an open-circuit state, and the capacitance is short-circuit to the high frequency. Therefore, under the action of coupling capacitance, the electric field intensity on the surface of the lightning receiver increases rapidly until the avalanche process is triggered, so that lightning leakage can be put into the ground in an instant, thus effectively achieving the purpose of lightning protection and safety protection.

Function
Conventional lightning protection can be divided into direct lightning protection, inductive lightning protection and comprehensive lightning protection. Lightning protection device against direct lightning generally consists of three parts, namely lightning receiver, down lead and grounding body; Lightning receiver is divided into ightning Rod, ground wire, Lightning belt and lightning conduction. The lightning protection principle of taking ightning Rod as the Lightning receiver is: ightning rod is connected to the underground through wires, forming an equal potential difference with the ground, and using its own height, the Lightning Cloud electric field with the electric field strength increased to the limit value is distorted, start ionization and downward pilot discharge; Ightning Rod produce tip discharge under the action of strong electric field, forming upward pilot discharge; The two combine to form lightning path, and then pour into the earth to achieve lightning protection effect. In fact, ightning rod is lightning rod, which can draw and discharge the surrounding lightning in advance, and transmit the lightning current to the ground through its own grounding conductor to avoid direct lightning strike of the protected object.
