Title: Lightning protection device
Inventor: IGARASHI MASAHIRO
IPC: H05F3/04
Filed: 2000-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a lightning arrester which does not induce the falling of a thunderbolt even if there is a lightening raid, while a conventional lightning conductor, sharpened to easily cause corona discharge or upward streamer, inductively attracts not only lightning right over but also lightning far away, positively lets the thunderbolt fall and results in power failure, communication interference or computer malfunction. SOLUTION: An electrode in a basin disc, metallic wire circular or metallic rod umbrella circular shape formed of metal or carbon fiber has a diameter few hundred times larger than that of a current lightning conductor. The central upper face is in a smooth or cavity (doughnut) form. Therefore, the field strength of the upper face of the electrode is extremely low hardly to cause and corona discharge and prevent the inducement of the falling of a thunderbolt. If a thunderbolt falls, a ground electrode and a ground conductor placed similarly to those in conventional arresting facilities prevents lower capability than conventional.
