Abstract:
1. A horn spark gap with a deion chamber of a non-blowout design having a multi-part insulating housing as a supporting and accommodating body for the horn electrodes and the deion chamber as well as means for conducting the arc-induced gas flow, wherein the insulating housing is divided in the plane spanned by the horn electrodes and forms a first and a second half-shell, characterized in that the horn electrodes have an asymmetrical form comprising a longer and a shorter electrode, wherein both electrodes extend almost in parallel or with a small divergence in the ignition region, the arc travel path between the electrodes is delimited in the direction of the deion chamber by a plate-shaped insulating material, wherein the plate-shaped insulating material is inserted into a respective first shaped portion of the respective half-shell in a form-fitting manner, the first shaped portions furthermore accommodate a ferromagnetic deposit of the arc travel path, wherein the plate-shaped insulating material electrically isolates the respective deposit from the electrodes, the half-shells have further second shaped portions which accommodate an insertable deion chamber part in a form-fitting manner, wherein apertures or openings in the respective half-shell are located between the respective first and second shaped portions and the shorter electrode ends in front of the deion chamber part, with the result that the gas flow only passes partially into the deion chamber.
