- the main contact of the turn-off side is first opened, after which the resistance contact of the receiving side is closed, so that between the two stages n and n + 1 through the Overload resistors limited compensating current flows. After the previously closed resistive contact has opened the disconnecting side, then closes the main contact of the receiving side, so that the entire load current from the new winding tapping n + 1 leads to the load dissipation, whereby the switching is completed.
- the vacuum interrupters used in this known tap-changer and numerous similar known embodiments instead of conventional mechanical contacts for load switching have a number of advantages. Since the contacts themselves are encapsulated in a vacuum, high switching capacities can be achieved. The encapsulated, hermetically sealed contacts also can not lead to the fouling and contamination of the surrounding insulating oil in the tap-changer by contact erosion or arcing. Furthermore, vacuum interrupters are now available as very compact components; they have a small footprint and require only relatively low actuation forces.

- a tap changer for uninterrupted switching between at least two winding taps of a tapped transformer with the features of independent claim 1 is proposed.
- a load branch is provided with at least two parallel paths.
- Each of these paths can comprise a series arrangement of at least one vacuum interrupter and at least one mechanical switching element, which in the present context can also be referred to as a variably adjustable or switchable switching contact.
- One of the at least two paths may be associated with a resistor arranged in series with the respective vacuum interrupter and the mechanical switching element.
- the at least two winding taps can be variably coupled together and / or acted upon with a load dissipation.
- the total of at least two vacuum interrupters and at least two mechanical switching elements with a defined time offset to each other in each case in different switching directions can be switched together.
- at least one of the mechanical switching elements has a relation to the other switching elements or vacuum interrupters and independent of the switching direction temporally relocated switching or trip time, whereby certain switching states can be realized in a simple, reliable and exactly reproducible manner by mechanical means.
- the relocated switching or tripping time has a defined time interval to the other switching or trip times of the other mechanical switching elements and vacuum interrupters.
- a temporally relocated switching or trip time having mechanical switching element switches all other switching elements and vacuum interrupters downstream.
- the tap changer according to the invention provides a rotatable switching shaft, the actuators are assigned for each actuation phase for the mechanical switching elements or vacuum interrupters, the actuators are each assigned to the switching shaft rotatable, concentric cams with frontal contours. These end contours can be formed in particular by projections, cams o. The like., Which are suitable for operating the switching elements and / or vacuum interrupters.
- the switching times triggered by the at least one cam plate corresponding to the mechanical switching element that is to be shifted in time are delayed in time regardless of its direction of rotation or of the direction of rotation of the switching shaft relative to the rotational movements of the other cams or of the other actuating elements.
- an additional permanent main contact may be provided on the tap changer and / or coupled thereto.
- each have a mechanical contact (MC) may be present, which carries a continuous current.

- the delayed in each switching direction switching or triggering of at least one mechanical switching element can be realized in the tap changer, that the at least one switching means and the cam associated therewith a freewheeling element for phase shifting the switching time is assigned depending on the direction of rotation of the switching shaft.
- This freewheeling element may in particular comprise a circular segment-shaped, for switching shaft concentrically arranged guide slot for a driver of the cam and a sleeve-like separator which is fixed to the housing fixed against the rotatable shaft and cams and decouples the rotational movements of the shift shaft and mounted on this cam from each other.
- the separator ensures in a simple and effective manner that the cam is not uncontrolled rotated when turning the shift shaft, for example.
