Abstract

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 (5) is provided downstream of the arcing chamber (3). Said intermediate chamber has a much greater volume than the arcing chamber (3). A pressure-proof flow channel (4), preferably consisting of metal, is provided as the connection between the arcing chamber (3) and the intermediate chamber (5).
