Abstract
1472036 Arc-quenching elements SIEMENS AG 3 March 1975 [3 April 1974] 8817/75 Heading H1N The arcing horns of high-voltage circuit breakers or other isolating devices are fitted with arc-quenching elements each comprising a tube containing a body of material which will vaporize with the heat of the arc, the tube having an axial slot at least in the region of the body to enable the vapour to emerge and quench the arc. The vaporizable material may be a plastics, a detonating substance, an admixture, or a succession of plastics bodies interspersed with detonators.
