Abstract

369,553. Heavy-current switches. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 20, 1930, No. 28189. Convention date, Sept. 23, 1929. Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] The point of separation of contacts 2, 3 is surrounded by a completely-closed chamber 1, 4, which is filled to a certain level with liquid 5, such as water, which, on an arc forming, is vaporized and sets up a pressure to extinguish the arc. The supply of liquid in the chamber can be maintained by a storage vessel, and gases may be led away from the chamber through automatically-opening valves.
