Definitions
- the invention is in the field of electronic components and can be used in the design of gas-filled discharge paths with at least two electrodes, in which a glass-like electrode activation compound consisting of several components is applied to at least one of the electrodes to ensure the ignition properties.
- a glass-like electrode activation compound is customary for setting the direct response voltage U ag , the base components being sodium silicate (Na 2 S ⁇ 0 3 ), casium silicate (Cs 2 S ⁇ O and metallic titanium (Ti) and small additives of sodium tetraborate as additives (Na 2 B 4 0) and gastric silicon oxide (MgO) in this known activation mass, the basic component sodium silicate is provided in about four to six times the amount of the other basic components casium silicate and titanium. It has been found that such a compound Activation mass does not meet the increased requirements for the constancy of the DC response voltage after surge and AC loads.
- the invention is based on the task of modifying the activation compound in such a way that the increase in the direct current voltage U ag after surge current load and the Drop in the DC response voltage U ag after AC load is reduced.
- potassium electrode K 2 S ⁇ 0 3
- casium tungstate Cs 2 W0 4
- an electrode activation composition has proven to be suitable in which the base components are contained in an amount of approximately 1 to 3 parts by weight and the additives in an amount of approximately 0.1 to 0.5 parts by weight.
- the figure shows a surge arrester which consists of a ceramic insulator 1 and two electrodes 2 and 3 inserted at the end.
- An activation mass 4 is applied to the surface of the electrodes provided with depressions, which contains sodium silicate, casium silicate, potassium silicate, casium wolfra at and metallic titanium as basic components.
- Magnesium oxide provided. The individual components are in the following proportions:
- Casium tungstate about 1 to 2 parts by weight, metallic titanium about 1.5 to 2.5 parts by weight, sodium tetraborate about 0.3 to 0.5 parts by weight, magnesium oxide about 0.15 to 0.25 parts by weight.
