    摘要: A gas-filled overvoltage arrester with an electrode activation compound. In order to ensure a high degree of adherence of the activation compound to the electrodes in a gas-filled hydrogen-containing overvoltage arrester, the activation compound comprises a first aluminum component, a second halide component, and a third dielectric or ferroelectric metal oxide component. These three components are present in the proportions of 50 to 70, 20 to 40, and 3 to 10 mol. %, respectively.

    摘要: A spark gap (1; 21; 50) is indicated with a cavity (3; 23; 43), which is enveloped by two terminal electrodes (7a, 7b; 27a, 27b; 47a 47b) having an electrical insulator (2; 22; 42) placed therebetween, and with a rod electrode (4; 24; 44), which projects into a tubular electrode (5; 25; 45). Provided in one implementation are recesses (11; 41) of the terminal electrodes on the side of the cavity (3; 43) and a guidance of the terminal electrodes on the inside wall of the insulator. In another implementation, reinforcement electrodes (12a, 12b; 27c, 27d) are provided, which are connected to one of the terminal electrodes. The two implementations can be combined.
