Spark gap (surge arrestor, series gap) which can be triggered

摘要

The invention relates to a spark gap which can be triggered and which has one or more spark channels which are located between the electrodes (1, 3) and are initiated by means of auxiliary electromagnetic energy, especially for switching heavy currents in surge circuits. In order to be able to ignite a very large number of spark channels virtually simultaneously in the case of such a spark gap with a very widely variable operating voltage, the invention proposes that the electrodes (1, 3) be constructed as a waveguide system which produces one or more spark flash-overs when a high-power microwave pulse is injected, which flash-overs initiate spark channels for the main circuit.
