Abstract

PURPOSE:To normally perform a redriving operation after a filter capacitor overvoltage operation by not allowing a reclosure of main circuit if the prescribed time is not elapsed after the filter capacitor is operated at the overvoltage. CONSTITUTION:When the voltage of a filter capacitor 7 is an overvoltage, an overvoltage suppression thyristor 6 is triggered by a trigger circuit 22, an overvoltage relay 23 is operated to open a unit switch 2 and a high speed breaker 4. When an operation command is released and a flip-flop 21 is reset, the relay 23 does not become OFF until charge stored in a capacitor 31 is discharged. The time that the relay 23 becomes OFF is set to a time that a current flowed to the thyristor 6 becomes a holding current or less of the thyristor 6. Thus, the redriving operation of an induction motor can be normally performed after the capacitor is operated at an overvoltage.
