Abstract
402,942. Oil-break switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Dec. 22, 1932. No. 36355. Convention date, Dec. 29, 1931. [Class 38 (v).] The oil employed in liquid-break switches has the air or oxygen removed and is then impregnated with carbonic acid gas. The air is removed from the oil by any known vacuum treatment and the gas is supplied either by blowing through the oil or by bringing the oil into finely divided particles which are passed under pressure into intimate contact with the gas. To increase the receptivity of the oil it may be heated or subjected to a pressure in excess of atmospheric pressure, the pressure and heating being effected in one or several applications. In use, if the switch detonates during operation the gas is suddenly and to a considerable extent freed from the oil and settles over the oil surface. Moreover, the products of the arc cannot ignite owing to the absence of oxygen. Any loss of the gas by diffusion in switches which are in communication with the atmosphere may be replaced by mixing with the oil a substance that gives off the inert gas.
