摘要:
The invention relates to an on-load tap-changer (1) having a switching tube (15), an energy accumulator (13) for adjusting a switch position of the switching tube (15), a detector (200) for detecting a switch position of the on-load tap-changer (1), and an on-load tap-changer mechanism (100). The switching tube (15) and the detector (200) are both mechanically coupled to the energy accumulator (13) via the on-load tap-changer mechanism (100).

The present invention relates to a motor drive having a position indicator for actuation of an on-load tap changer or diverter. The invention proposes a motor drive for actuating an on-load tap changer or diverter. This diverter has a drive motor which drives at least one load gear and an indicator gear, wherein the load gear has a first drive shaft, having a first drive pulley which is mechanically connected thereto and is connected to the drive motor, and a second drive shaft having a second drive pulley which is connected thereto. The first and second drive pulleys are mechanically coupled, wherein the second drive shaft itself is operatively connected on the first side thereof to the on-load tap changer or the diverter and can be connected by the second side thereof to the indicator gear. The indicator gear co-operates with a position indicator, by means of which the currently activated position of the on-load tap changer or diverter can be displayed, and wherein a switchable coupling device can be provided between the position indicator and the load gear.

The invention relates to an electric motor-operated on-load tap changer (1) comprising an emergency drive. An electric motor (3) and a power store (13) of said on-load tap changer (1) are mechanically coupled by means of a gear (5) that is provided with a gear housing (90). The gear (5) comprises a gear shaft (61) on which a toothing (55) is designed. For manual emergency operation, the claimed gear shaft (61) has an extension (62) which comprises a free end (65) for attaching a tool (95). The invention also relates to a method for adjusting a defined switching position of an on-load tap changer (1) when in an emergency operation mode.
