A method carries out a switchover of an on-load tap-changer using a drive system. The drive system includes at least one motor which acts on a drive shaft, a control device and an encoder system which is directly or indirectly coupled to the drive shaft. The method includes receiving a signal for switching the on-load tap-changer from the control device; determining by the control device whether switching to a current tap was performed from an upward or downward direction, and whether switching will be performed to a next tap in the upward or downward direction; selecting, on the basis of the determination, one of a plurality of travel profiles for the drive system of the on-load tap-changer, on the basis of which the switchover is carried out; and carrying out and monitoring the switchover by the drive system according to the selected travel profile.

A drive system drives at least one switch. The drive system includes: a drive shaft, which is configured to connect the drive system to the at least one switch and at least one motor, which is configured to be coupled to the drive shaft; a feedback system which is configured to determine a position of the drive shaft and, based on this position, to generate a feedback signal; and a controller which, based on the feedback signal, selects a stored travel profile from a plurality of travel profiles and controls the motor in accordance with the selected travel profile.

Drive system for a switch, and method for driving a switch

A method for carrying out a switchover of a switch from a current switching position to a target switching position by means of a drive system. The method includes receiving, by the drive system, a switching signal from a control device, determining, via a feedback signal of a feedback system, at least one value for a first position of a drive shaft of the drive system, determining, by the control device, a value for a second position of the drive shaft on the basis of the target switching position, to be moved to, of the switch, and ascertaining, by the control device, a difference between the value for the first position and the value for the second position of the drive shaft. The control device, depending on the feedback signal, acts on a motor until the value for the second position of the drive shaft is reached.

A drive system drives a switch. The drive system includes: a drive shaft connecting the drive system to the switch; a motor configured to drive the drive shaft; a feedback system; and a controller. The feedback system is configured to: determine at least one value for a position of the drive shaft; and generate a feedback signal based on the at least one value. The controller acts on an operation of the motor depending on the feedback signal.
