Abstract

363,437. Arc-rupturing switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Prince, D. C. ; 1424, Wendell Avenue, Schenectady, New York, U.S.A.) Oct. 1, 1930, No. 29405. Convention date, Oct. 1, 1929. [Class 38 (v).] During the opening movement of a main circuitbreaker 1, a member 10 on the operating rod 3 engages a detent 9, thereby allowing a spring 8 to open a switch 7 and insert in series with the breaker 1 a high-vacuum H.T. fuse 6 of the character described in Specification 308,665, [Class 38 (i), Electric couplings &c.]. If at this point in the travel of the movable part of the breaker 1 the arc persists, circuit is finally broken by rupture of the fuse 6. In a modification, the rod 3 operates a switch to remove a shunt from a solenoid, which is energized from a current transformer in the line and opens the switch 7.
