Title: Starter for large capacity motor
Inventor: ANAYAMA OSAMU
IPC: H02J3/38
Filed: 1989-10-31
Abstract: PURPOSE:To suppress voltage drop due to starting current by controlling a switch for switching a load side bus connecting circuit of a transformer for feeding power to a load. CONSTITUTION:A throw-in command is provided to a feeder circuit switch 10 for a large capacity motor 9 on condition that a switch 8 is closed, and the large capacity motor 9 is started upon closure of the switch 10. When the value of current detected through a current transformer 11 arranged in the feeder circuit for the large capacity motor 9 drops below a prescribed level after elapse of a prescribed time necessary for attenuation of starting current of the large capacity motor 9, the bus connecting circuit switch 8 is opened thus completing starting operation of the large capacity motor 9. If the current of the motor 9 has not dropped below the prescribed level even after elapse of the prescribed time, it is considered abnormal starting and an alarm signal is produced. By such arrangement, voltage drop due to the starting current can be suppressed.
