Suzhou three-phase auto transformers | autotransformers principle Jiangsu | Suzhou autotransformer factory ..

SZG autotransformer is mainly used in 50Hz / 60Hz voltage industrial power lifting; input voltage 380 V output voltage 220V, 200V, 110V, etc., general and imported equipments. LW-QZB series of auto-transformers for AC 50Hz, rated voltage of 380V, power 14KW-300KW three-phase squirrel cage induction motors non-frequent voltage starting, in order to improve the impact on the transmission network during motor starting. Scope: LW-QZB series autotransformer application and 380V50Hz power 300KW and the following three-phase squirrel cage induction motor for infrequent operating conditions starting the buck; the use of auto-transformer step-down features, reduce the motor starting current, in order to improve the impact on the transmission network motor starting. Features: This series transformer with 65% (60%), 80% of the two starting voltage tap, if need smaller starting torque can be used 65% (60%) of the tap, a large torque can be used 80% of taps . The transformer can be fitted in the XJ01, J11 series auto decompression starting box as the main parts.
