Abstract
380,658. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Dec. 2, 1931, No. 33453. Convention date, Dec. 9, 1930. Addition to 379,804. [Class 38 (v).] In an " expansion " switch wherein the pressure developed by the arc in the expansion chamber is conserved until it is adequate to lift the cover, of the chamber and thereby open a large peripheral passage to permit of rapid expansion as in the parent Specification, additional means are employed to ensure that the cover remains raised at the zero of the A.C. cycle notwithstanding the sudden reduction of pressure. In the arrangement shown in the Figure, the cover 34 of the expansion chamber 33 carries with it (when adequate pressure has been developed) a piston 40 working in the outer condensation chamber and connected to the cover by guided pins 35 on which springs 42 are arranged. The pistons have valves 45, 46 which open to allow free upward movement but close to retard return movement of the piston thereby ensuring that the cover is held raised from the expansion chamber during the zero passage. In a modification, the walls of the chamber are made of magnetic material and surrounded by a coil carrying the main current. The cover is provided with magnetic insets so that it is held down electromagnetically until just before the zero of the A.C. cycle when the pressure developed forces it against the action of springs into the raised position at the zero of the A.C. cycle.
