Spain Apollo discharge lightning rod in advance (also known as a lightning rod APOLLO) has a chain reaction of active lightning protection device - active lightning rod, mainly by three kinds of systems (air power capacitors, high-voltage pulse delivery system, the current discharge system) formed, and has Double instantaneous discharge device is multi-layered with the isolation and the harsh environment of material protected by watertight, non-aging dangerous, maintenance-free, has been widely used in all types of buildings against lightning directly stroke project.
Air Power Capacitor: 90% of the cases, the Thundercloud lower negative charge accumulation, the earth sensor produces a positive charge. When Thundercloud charge accumulation to a certain extent, Thundercloud on earth can be regarded as a field strength of a great flat capacitor, the earth is being charged through the lightning rod to reach the tip, due to a lightning rod APOLLO (Apollo early discharge lightning rod) between the shell and the needle bar with insulation material and two sets of instantaneous discharge device isolation, enclosure sensor capacitor potential, its value is much lower than the tip potential, resulting in a strong potential difference.
Lightning start the system: Apollo early discharge lightning rod surrounded by built-in with a group of relying on changes in the electric field generated high-voltage pulse transformer-type transmitters. When the electric field is very high around the time (more than 50kV / m), lightning rod will absorb the energy build-up devices and accumulated by the floating potential difference through the formation of an external power to pull the conversion of energy. Then transformer type high-voltage transmitter radiation in the instantaneous high-voltage pulse in the atmosphere, ionizing the air, to enhance and enlarge lightning around the electric field strength will be increased up Leiyun discharge potential, Thundercloud and the lightning rod to shorten the distance between the insulation.
Lightning current discharge system: As this process has been strengthening its Thundercloud and the lightning rod of insulation between the shorter and shorter distances, the field strength greater the further ionization of air leading up to discharge and main discharge occurred.he high-voltage pulse of time necessary to launch in a mine-leading (Tracer) on the discharge time to reach the ground before the launch of its mine-leading average speed is 1m/μs, the entire operation process ahead of time difference, known as the discharge time in advance.
APOLLO active lightning conductor (TA ahead of discharging lightning) has the following characteristics:
→ pre-empt the discharge time of 30μs ~ 60μs, which give priority to quoted mine into the earth;
→ in the same mounting height, the Franklin lightning protection than ordinary large radius of several times;
→ pure physical structure type lightning rod, the internal non-electronic devices, non-aging, maintenance-free.
→ good looks, choose stainless steel material that can be installed in a poor environment mine sites.
→ lightning protection devices, light weight, low-load requirements.
