Abstract

PURPOSE: To prevent erroneous function of high speed braking by duplifying brake circuit.
CONSTITUTION: When the condition of main machine stopping condition relay 4 is satisfied and parallel circuit breaker 52 is opened, time limit device 52T for counting the time after disaarangement is functioned. Normally time limit device 52T sets the time elapsed after disaarangement with 100% rate untill it reaches to 30% speed. When the rotation of generator drops below 30% of rated one, condition of speed relay 14-1 is satesfied while simultaneously the condition of time limit device 52T is satisfied to function aux. relay 14-1X thus to function braking solenoid 75S
