摘要

The device (2) has electric arc-discharge plates (23) that are arranged parallel to each other, and a part (50) made of gaseous plastic material. The part overlaps two of the discharge plates (23) and extends parallel to an electric arc running direction (32). Electric arc-discharge plates (24, 25) and laminar strips are provided with corresponding locking units. Insulating walls (22) are provided for fixing the discharge plates and extend parallel to the electric arc running direction.
