Abstract

PURPOSE: Not to stop the motor and to continue its operation by selecting and detecting temporary power-off and temporary open phases and detecting speed of an induction motor and sequentialy controlling the circuits of a power breaker thyrister switches, contactors, invertors.
CONSTITUTION: A power breaker SI is set at the power side of a wound-rotor induction motor 1M, on the output side of a rectifying circuit SR is equipped a surge absorbing condenser C3 in series with a thyrister switch (THR) S2, and a high resister R3 is connected in parallel with a contactor S3 which opens the THS by breaking the condenser C3. The DC current transformer DCCT which detects the DC output voltage IDC of the rectifying circuit SR and a current transformer C which detects the output voltage of an inverter circuit SCR are installed. Therefore, not only temporary power-off and temporary open phases are detected separately but also the speed of the motor 1M is detected. According to that condition the power breaker SI, THRS2, contactor S3 invertor circuit SCR are controlled sequentially so that the motor 1M can maintain its operation without stopping itself.
