It is often used for infrequent
step-down starting of large capacity squirrel cage asynchronous motors to improve the impact on the transmission network during motor
starting. Although it is an old-fashioned starting device, the use of its multiple tap depressurization can not only adapt to the needs of
various load starting, but also obtain larger starting torque. Its function is to use the characteristics of transformer depressurization to
reduce the starting current of the motor. Three phase self coupling step-down starting transformer - Applicable occasions: Suitable for
infrequent step-down starting of three-phase squirrel cage asynchronous motors with a power of 14KW-3000KW.
