摘要： 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.

摘要： 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.

摘要： In a method for cleaning an on-load tap changer (19) in a regulating transformer (20), provision is made for the on-load tap changer (19) to comprise a moving contact (11) and a fixed contact (12); for a cleaning signal to be generated; for the moving contact (11) to be frictionally moved relative to the fixed contact (12) on the basis of the cleaning signal. An on-load tap changer (19) in a regulating transformer (20) comprises: —a moving contact (11) and a fixed contact (12); —a contact drive (17) which is coupled to the moving contact (11); —a control device (18) which is connected to the contact drive (17) and is designed in such a manner that the control device can generate a cleaning signal and can transmit said signal to the contact drive (17); wherein the contact drive (17) is designed in such a manner that the contact drive can frictionally move the moving contact (11) relative to the fixed contact (12) on the basis of the cleaning signal.
