Description
Technical Field
The utility model relates to a distributed ionization lightning arrester, and belongs to the technical field of lightning protection.
Background
The lightning disaster is the third meteorological disaster which is just next to rainstorm flood and landslide. The lightning has high discharge voltage, large current amplitude, short discharge process and great destructiveness, seriously threatens the life and property safety of human beings, and meanwhile, the severe weather often influences the safe and stable operation of power grids, telecommunication and traffic and also influences the effective running of major military operations. Therefore, the steps for developing the lightning protection device are never stopped in the industry for researching the lightning mechanism.
The traditional lightning protection device is provided with a lightning rod, a lightning rod which discharges in advance, a semiconductor lightning arrester and the like.
The working principle of the lightning rod is that a thundercloud electric field is attracted to be concentrated on a metal rod of the lightning rod to increase the strength of the electric field at the end of the metal rod, so that the thundercloud electric field breaks through air and discharges strong thunder and lightning into the ground through a grounding body of the lightning rod. The device has the advantages of simple structure, stable performance, convenient maintenance, small protection angle, high requirement on grounding resistance, contact voltage and step voltage risk, easy formation of induced current on a protected object in the lightning receiving process and unsuitability for protecting weak current equipment.
The lightning rod which is discharged in advance generates a head-on pilot which is faster than the common lightning rod. Before the natural head-on leader is formed, it is rapidly propagated in the direction of lightning until the lightning is captured and guided to the ground. The device can effectively avoid the phenomena of 'shielding failure' and 'side failure' of the traditional lightning rod. But the protection radius is close to that of a common lightning rod, and the requirement on the ground resistance is high. There is also a risk of contact and step voltages.
The semiconductor lightning arrester is designed by utilizing the point discharge principle of a metal needle electrode. Plasma is generated under the action of the thundercloud electric field, and the thundercloud charges are neutralized. The device has the capability of neutralizing the descending leader of thundercloud, and can effectively weaken the main discharge current of lightning stroke. But the flux is limited, and the semiconductor lightning arrester is usually destroyed by lightning.

With the enhancement of the thundercloud electric field, the positive charges at the tip end are gradually increased, the negative charges are accumulated on the cylinder wall of the discharge cylinder under the repulsion of the thundercloud electric field, the discharge electrode in the discharge cylinder is positively charged, and with the increase of the charges, the strong electric field can ionize air to generate a large amount of corona ions. Positive corona charges are diffused into the air and continuously interact with thundercloud charges to weaken the development speed and strength of the descending leader of the thundercloud, and meanwhile, a corona shielding layer is formed on the lightning driver and a protected object to inhibit the starting of the ascending connection leader and block the conduction of an upper channel and a lower channel, so that the lightning stroke phenomenon in a protection range is avoided.
