KUC711AE 3BHB004661R0001 ABB KUC711AE

KUC711AE

The main circuit of KUC711AE 3BHB004661R0001 device performs two functions of rectification and magnetic extinction. The system adopts three-phase fully controlled bridge silicon controlled rectifier circuit to provide DC excitation current to the rotor windings of synchronous motor. KUC711AE 3BHB004661R0001 de-magnetized circuit is composed of silicon controlled 7, 8KGZ and diode GZ in reverse parallel, in fact, it is composed of a high-power electronic switch, to complete the synchronous motor in the asynchronous starting process into the starting resistance, automatically cut after the start, ensure the synchronous motor in the asynchronous starting period, Rotor excitation winding is neither open nor short circuit, so as to avoid the excitation winding under overvoltage and overcurrent. KUC711AE 3BHB004661R0001 excitation device control part: The system control part includes S7200PLC, Pro-face touch screen, KGLF-2 microcomputer excitation controller three parts. KUC711AE 3BHB004661R0001 PLC mainly completes the relay circuit logic control work mode switching, PI adjustment during operation and external communication and other work, Pro-face touch screen mainly completes the system parameter setting and operation fault, working time, set operation parameters information query, Pro-face touch screen has excitation current and excitation voltage record curve information viewing.
