LIGHTNING PROTECTOR WITH IGNITION DEVICE WITH SLIDING ELECTRICAL DISCHARGE ALONG A DIELECTRIC

摘要

The lightning rod including the detonator includes an insulator having a center electrode 110 having a free end 111 and a ground end 112, and an outer surface 121a surrounding the center electrode and continuously contacting the free end of the center electrode. And an outer surface of the insulator part 121 ′ a partially uncovered portion 121 ′ a of the outer surface connected to the free end of the center electrode defines an insulator bridge between the outer electrode and the free end of the center electrode. A covering electrically conductive external electrode 122 is provided, wherein the bridge guides the spark between the free end of the central electrode and the conductive external electrode that is charged in a suitable atmospheric state during discharge of the external electrode.
