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 an electrode activation compound consisting of several components is applied to at least one of the electrodes to ensure the ignition properties.
- a surge arrester which has two electrodes inserted on the end face into a ceramic insulator, the facing electrode surfaces of which are coated with an activation compound, which is arranged in depressions in the electrode surface.
- Arranged on the inner wall are a plurality of ignition lines which run in the axial direction of the ceramic insulator and which are designed as so-called center ignition lines without a direct connection to the electrodes (US 4,266,260 A / DE 28 28 650 C2).
- gas-filled surge arresters it is common for gas-filled surge arresters to be arranged in a space which is encapsulated against external light during their operation are to arrange an additional ionization source in the form of a punctiform deposit made of a radioactive material on the inner wall of the insulator.
- the gas filling of the surge arrester can consist of a radioactive gas (US 3,755,715 AI).
- a radioactive gas US 3,755,715 AI
- an electroluminescent material as an additional ionization source, which is applied to the inner wall of the insulator as a coating connecting the two electrodes of the conductor (DE 43 18 944 C2).
- the invention is based on the object of designing the discharge gap in such a way that it has a very small size even without the use of an additional ionization source Has ignition delay in the dark room.
- the invention provides that, in addition to the usual base component in the form of one or more alkali metal or alkaline earth metal halides and / or sodium and / or sodium and / or potassium silicate in an amount of 30-60% by weight as further components a barium compound and a so-called transition metal in metallic form such as titanium, hafnium, zirconium, vanadium, niobium or chromium in an amount of 5 to 25% by weight and one Oxide compound made of cesium and a so-called transition metal such as tungsten, chromium, molybdenum, niobium or vanadium, i.e.
- a barium compound and a so-called transition metal in metallic form such as titanium, hafnium, zirconium, vanadium, niobium or chromium in an amount of 5 to 25% by weight and one Oxide compound made of cesium and a so-called transition metal such as tungsten, chromium, molybdenum, n
- barium compound preferably a barium-aluminum alloy (BaAl 4 ), and a so-called transition metal in metallic form among the components of the electrode activation composition such as titanium, hafnium, zirconium, vanadium, niobium or chrome.
- a barium aluminum and metallic titanium as components of an activation composition is known per se (DE 26 19 866 C2), as is the use of the base component in the form of one or more alkali or alkaline earth metal halides and / or sodium - and / or potassium silicate (DE 26 19 866 C2, DE 37 23 571 C2, DE 27 35 865 C2).
- oxide compound composed of cesium and a transition metal such as zirconium, tungsten, tantalum and molybdenum as the emission material for discharge lamps, in order thereby to achieve a low breakdown and operation throughout the life of the lamp ⁇ to allow voltage.
- the oxide compound is dispersed in the pores of a sintered body made of high-melting metal. yaws. Barium aluminate or barium tungstate can be used as further emission material (DE 30 08 518 C2).
- an activation compound is incorporated into the waffled surface of the electrodes, which contains potassium chloride in an amount of 50% by weight.
- metallic titanium in an amount of 17% by weight
- barium-aluminum compound in an amount of also 17% by weight
- cesium-tungstate in an amount of 16% by weight.
- the activation mass can contain smaller proportions of oxides of cesium and the transition metals used, that is to say cesium oxide, titanium oxide and tungsten oxide.
