Patent GB-868774-A (GB)
Title: An anti-hunting arrangement for electric circuit breakers
Inventor: SLANY JAROSLAV
IPC: H02H7/22
Filed: 1959-03-13
Abstract: 868,774. Protective arrangements. ZAVODY V.I. LENINA PLZEN, NARODNI PODNIK. March 13, 1959, No. 8772/59. Class 38 (5). In an anti-hunting arrangement for controlling the operation of an air-blast circuit-breaker, the closing of a control switch 12 effects the energizing of a closing valve solenoid 2. The closing of the circuit-breaker causes the operation of an air-pressure-operated rotary switch to open contacts 4 and close contacts 3. Should the circuit-breaker be closed on to a fault, the contacts 11 of an over-current relay are closed to effect the energizing of the opening valve solenoid 1 through the contacts 3, and the energizing of the coil 7 of a relay 6 which changes over its contact 9. The opening of the circuitbreaker is accompanied by the restoration of the contacts 3, 4 but the circuit-breaker is not automatically reclosed if the control switch 12 is held closed as the changing over of the contact 9 has completed a holding circuit for the relay 6 and has opened the circuit for the closing solenoid 2.
