Title:
MUTUAL-INDUCTANCE CONTACTLESS CURRENT STARTER FOR COMMERCIAL REFRIGERATION COMPRESSOR MOTOR
Document Type and Number:
WIPO Patent Application WO/2016/004783
Kind Code:
A1
Abstract:
A mutual-inductance contactless current starter for a commercial refrigeration compressor motor. A permanently running capacitor (C2) is connected between a primary winding leading-out end (M) and a secondary winding leading-out end (S) of a motor. A primary and secondary winding combination leading-out end (L) is connected to an end B of an alternating-current power supply. The mutual-inductance contactless current starter comprises a current transformer (L1), bidirectional controllable silicon (T) and a starting capacitor (C1). One end (1) of a primary coil of the current transformer (L1), one end (3) of a secondary coil of the current transformer (L1) and a T1 pole of the bidirectional controllable silicon (T) are connected to an end A of the alternating-current power supply. The other end (2) of the primary coil of the current transformer (L1) is connected to the primary winding leading-out end (M) of the motor. The other end (4) of the secondary coil of the current transformer (L1) is connected to a G pole of the bidirectional controllable silicon (T). A T2 pole of the bidirectional controllable silicon (T) is connected to one end of the starting capacitor (C1). The other end of the starting capacitor (C1) is connected to the secondary winding leading-out end (S) of the motor. The mutual-inductance contactless current starter is energy-saving and highly efficient, has a simple circuit structure and high universality, can withstand high current, and ensures reliable and safe starting of the motor.
