FIELD: electricity.

SUBSTANCE: drive comprises an AC converter-fed motor (1) with permanent magnets, the output shaft (2) of which is connected to a driving shaft (3) of the OLTC device, a programmable logical controller (4), a unit (5) of power switching of the AC converter-fed motor windings (1) with permanent magnets, a sensor (6) of the switching angle of the AC converter-fed motor windings (1), a sensor (7) of position and speed of the AC converter-fed motor (1) shaft, a control panel (8), a panel (9) of OLTC device position indication, a source (10) of uninterrupted supply. The output of the source (10) is connected to the first input of the controller (4), the second input of the controller (4) is connected to the output of the panel (8), its third input is connected to the output of the device for remote control of the OLTC drive, its fourth input is connected to the first output of the unit (5), its fifth input is connected to the output of the sensor 6, its sixth input is connected to the output of the sensor (7), the first output of the controller (4) is connected to the first input of the unit (5), its second output is connected to the input of the panel (9), its third input is connected to the input of the device for remote control of the OLTC drive, the second input of the unit (5) is connected to the source of supply, its third input is connected to the output of the sensor (6), its fourth input is connected to the output of the sensor (7), its second output is connected to windings of the AC converter-fed motor (1), at the same time the sensor (6) and the sensor (7) are placed on the common axis with the AC converter-fed motor (1).

EFFECT: higher operational reliability of the drive, reduced labour intensiveness in manufacturing, higher accuracy of positioning during regulation.
