Abstract
PURPOSE: To reduce ordinary maintenance inspection frequency by relieving breaker which is frequently used at the time of electrical control of synchronous machine of its selectrical damage.
CONSTITUTION: The control unit consists of the synchronous machine S provided with the field winding 2 to be energized by the DC power source 19 through the field switch 3, the breaker 4 to short-circuit armature winding, and the load switches 16 to 18 connected in parallel with each phase of the switch. To control the synchronous machine electrically, the field switch 3 is first opened, and then after making the current of the field winding 2 zero, the load switches 16 to 18 are closed concurrently. At this time, a short circuit current corresponding to the residual magnetism of synchronous machine flows in each phase and the potential between the fixed pole and movable pole of the breaker 4 becomes zero. Afterwards, the breaker 4 is closed. Thus, the breaker can be worked within the usual operation duty.
