ABSTRACT:
This invention aims at preventing a thunderbolt attack detecting circuit from determining that no thunderbolt is approaching because the thunderbolt attack detecting circuit turns to its initial condition due to power interruption caused by an approaching thunderbolt and is changed over into a normal condition in the thunderbolt approaching status maintained. This thunderbolt disaster protecting apparatus includes a thunderbolt attack detecting circuit for determining whether or not any thunderbolt is approaching by detecting a thunderbolt signal and a switching mechanism for changing over to the normal condition in which a protection object device is connected to an electrical path or to thunderbolt resisting condition in which the protection object device is separated from the electric path.
