Feasibility of New Lightning Protection Technology
The difference between traditional lightning protection theory and our new lightning protection technology theory:
Theory is the foundation of technical measures, and the theoretical basis of traditional lightning protection technology is the theory of energy (thundercloud charge) release. It is believed that the lightning rod's lightning strike can release the energy (thundercloud charge) of the thundercloud to the earth through the lightning rod and grounding system (energy release to the grounding body).
Our new lightning protection technology theory believes that lightning energy is consumed and consumed before the zero potential point of the earth.
The traditional lightning protection technology measures start from the mechanism of lightning energy release, and the necessary condition for direct lightning protection measures is that the lightning rod must flash with the thunderstorm cloud. Only through flash can the energy of the thunderstorm cloud be released. Moreover, the smaller the resistance of the grounding body system, which is one of the components of the lightning protection system, the greater the discharged current and the faster the lightning discharge speed. This theoretical understanding suggests that the grounding resistance in lightning protection measures should be as small as possible.
According to the theory of new lightning protection technologies, lightning energy is consumed before the zero potential point of the earth; That is to say, the charges in the thunderstorm cloud are automatically distributed freely from high potential to low potential through the lightning current, and the transferred charges are finally distributed entirely on the surface of the system through which the lightning current flows; The position of the last charge point is the zero potential reference point of the earth; The speed of lightning consumption is independent of the impedance of the path it passes through. The magnitude of the impedance only depends on the corresponding magnitude of the lightning current and lightning potential that consume instantaneous power. From the perspective of lightning consumption, the resistance of the grounding body is a part of the lightning energy consumption path. For the resistance of the grounding body in series, the greater the better. The larger the resistance of the grounding body, the smaller the power consumption in other series positions, and the safer the system, When the resistance of the grounding body is zero, its effect is zero. Therefore, our new lightning protection technology measures adopt a small current, high potential consumption method, and all energy is consumed in the external series connection path outside the protection system.
The traditional lightning protection measures involve products such as lightning rods, grounding systems, SPD, etc. that must undergo direct lightning strikes, and the current passing through is the main parameter required for their quality.
Our lightning protection products must eliminate lightning rods that directly strike the ground within the protection range.
Traditional lightning protection engineering is a compliance project with national lightning protection standards, which cannot guarantee the reliability of protection;
Our new lightning protection technology project is a technical reliability project that can guarantee the safety of any system within the protection range 100%.
Traditional lightning protection measures consume lightning energy at the end of the lightning current path, which is the most dangerous high potential range at the front end of the lightning current path.
The ground potential counterattack is the fundamental cause of lightning damage to equipment, and cannot be solved by shielding, grounding, and parallel connection of SPD modules with power ports.
In fact, from a scientific perspective, lightning energy is consumed before the zero potential point.
It should be said that the effective protective measures for the counterattack against geoelectricity should be shutdown, isolation, and elimination, and the most ideal method is elimination.
Eliminate direct lightning strikes and lightning arcs within the protection range!
Eliminate direct lightning strikes and lightning flashes within the protection range!
Eliminate the stacking of ground potential within the protection range and counterattack!
Fundamentally solve the technical problem of lightning protection reliability.
