Abstract

The invention relates to a horn spark gap lightning arrestor with a deion chamber (6) for quenching arcs in a housing (1) and controlling the internal gas flow for adjusting a different response of the arc produced in the case of power pulse current loading, on the one hand, and of the arc induced by follow-on current, on the other hand. For this purpose, the distance between the opposite electrode faces of the horn spark gap in the striking region is kept very small and there is only a slight widening of the distance in the diction of the end of the horn spark gap in order to prevent undesired migration of the arc in the event of lighting pulse current.
