Abstract

865,154. Protective arrangements. ALLISCHALMERS MANUFACTURING CO. June 9, 1958 [June 17, 1957], No. 18349/58. Class 38 (5). [Also in Group XXXIX] In a circuit-breaker control system, capacitance means supply a single pulse of unidirectional current to the control winding 10 of a transductor 5 to permit sufficient current to flow through the reactance or operating windings 8, 9 to energize the closing coil 3 of a circuit-breaker to close the circuit-breaker. In Fig. 1, the transductor is of the auto-selfexcited bridge-rectifying type and has a D.C. bias winding 11. The operating winding 10 is only energized during the charging period of a capacitor 31 when a " closing " push-button switch 16 is operated so that " pumping " cannot occur if the switch 16 is maintained closed when the circuit-breaker is closed on to a fault and trips open. The capacitor 31 discharges through a resistor 32 when the switch 16 is opened to prepare the system for a reclosing operation. In an alternative arrangement, the transductor is a simple saturable reactor with a D.C. control winding and A.C. operating windings. In each case the circuitbreaker is tripped on the operation of a switch 28 to energize a trip coil 4 which actuates a latch 58 to release toggle linkage 49, 50 and permit the circuit-breaker to open.
