Abstract
The invention relates to a lightning protection spark gap assembly. The lightning protection spark gap assembly comprises: a lightning protection spark gap (1); a safety fuse device (8) which can be triggered by a bridge initiator (7) and which is connected between a first or second voltage line (S1, S2) and a corresponding main connection (1, 1b) of the lighting protection spark gap (1); and an indicator device (4′) for detecting a secondary current flow connecting to a pulse current flow or a corresponding portion of the secondary current flow, and for triggering the safety fuse device (8) by activating the bridge initiator (7) when the detected secondary current flow or the corresponding portion of the secondary current flow fulfills a first predefined criterion, wherein the lightning protection spark gap (1) has a first and a second divergent electrode (21a, 21b) and an arcing chamber (25), and wherein the indicator device (4′) is electrically connected to the first or second divergent electrode (21a, 21b) and/or the arcing chamber (25) in such a way that it detects the secondary current flow or the corresponding portion of the secondary current flow in the area (L) in which the secondary current arc flows.
