A spark-gap arrangement encapsulated in a pressure-proof housing, for diverting harmful disturbances due to overvoltage, including at least two electrodes disposed substantially opposite one another in a housing that is conductive or provided with a conductive coating, between which a discharge space is formed and which are insulated from the housing. In accordance with the spark-gap arrangement a trigger voltage to form a subsidiary spark gap in the discharge space can be applied directly by the conductive housing, so that by the subsidiary spark gap the main spark gap between the main electrodes can be ignited.

Pressure-resistant encapsulated air-gap arrangement for the draining off of damaging perturbances due to overvoltages

The invention relates to a spark gap arrangement for use in power supply systems, especially in low-voltage systems, comprising an arcing chamber in which an electric arc is formed between two electrodes of the spark gap. An intermediate chamber ( ) is provided downstream of the arcing chamber ( ). Said intermediate chamber has a much greater volume than the arcing chamber ( ). A pressure-proof flow channel ( ), preferably consisting of metal, is provided as the connection between the arcing chamber ( ) and the intermediate chamber ( ).
