Abstract
PURPOSE: To ensure a large starting torque by restricting the starting current through combination of a starting transformer provided on the primary side of a motor and Δ connection empolying the motor having the primary winding changeabl in Y-Δ.
CONSTITUTION: When starting a motor 1, a contactor system is closed in the order of a Δ connection contactor 2, a starting transformer neutral point contactor 3 and a main contactor 4. Here, the motor starts with the primary side winding and the Δ connection through a starting transformer 7 on the power supply side. After the starting is completed, the motor is operated as rated according to the following procedures in order: closing an auxiliary contactor, opening the starting transformer neutral point contactor 3, opening the Δ connection contactor 2 and closing a Y connection contactor 6.
