Abstract
917,631. Protective arrangements. WHIPP & BOURNE Ltd., and WHIPP, C. L. Feb. 24, 1959 [Feb. 25, 1958], No. 6024/58. Class 38 (5). An anti-pumping circuit-breaker control system comprises an electrically-controlled device C for closing the circuit-breaker, a contactor A for controlling the device C, a manual switch 22 for controlling the contactor, and a relay B which is initially controlled by the device C and has maintaining contacts B1 and normally closed contacts B2 in series with the contactor A. When the switch 22 is closed the contactor A closes its contacts A1 to energize the device C. The device C closes the circuit-breaker and closes contacts C1 to energize the relay B which opens contacts B2 to de-energize the contactor A and closes the maintaining contacts B1. Should the circuit-breaker trip open whilst the manual switch 22 is held closed, the circuit-breaker does not automatically reclose as the relay B at contacts B2 prevents the reclosing of the contactor A. Contacts 23, closed when the circuitbreaker is closed, complete a holding circuit for relay B when the switch 22 is released. Should the contacts C1 re-open when the circuit-breaker is closed with the device C de-energized, then further contacts 24, closed by the circuitbreaker when closed, are provided. Alternatively a single set of contacts operated by the circuit-breaker may be connected across the switch 22 and contacts B1.
