In this known arrangement, it is provided that the two pivotable contact fingers or Kontaktfingerpakete are mounted on an electrically conductive common axis which is arranged parallel to the rotatable switching shaft and that in each of the two pivotable contact fingers or Kontaktfingerpakete a separate mechanical, electrically conductive stop for Formation of each switched end positions is assigned.

DE 10 2011 107 460 A1 describes a diverter switch for a tap changer for uninterrupted switching between winding taps of a tapped transformer. The tap changer has a selector for powerless preselection of the new winding tap to be switched to below, and a diverter switch for subsequent rapid uninterrupted switching from the previous to the preselected new winding tap. The diverter switch has two load branches, each of which has a permanent main contact in parallel with each other for continuous current operation in stationary operation and at least one switching contact and at least one resistance switching contact. The tap changer is driven by a motor drive in such a way that the motor drive by a continuous rotational movement of a drive shaft actuates the selector and at the same time biases a power storage of the diverter switch. Due to the triggered energy storage, the switching contacts and resistance switching contacts in a switch-specific sequence are suddenly connected. The permanent main contacts of both load branches are actuated directly from the drive shaft so that at the beginning of each switch the permanent main contact in the previously leading the load current branch slowly opened and closed as completion of each switch the permanent main contact in the new, the load current branch is slowly.

In the 1 is a first embodiment of a switch 10 and a first embodiment of a switching device 11 with a switching shaft 12 and this switch 10 shown schematically.

In these embodiments, the switch comprises 10 a pedestal 13 , a primary fixed contact 14U , a primary swivel contact 15U , a primary contact carrier 16 , a primary drive mechanism 17 and a bearing tube 18 , At the pedestal 13 is the shift shaft 12 rotatably arranged and the primary fixed contact 14U attached. The primary swivel contact 15U is pivotable about a pivot axis A on the base 13 stored that he has a first end position in which he is at the primary fixed contact 14U is applied, and a second end position in which it is from the primary fixed contact 14U is isolated, can take. In the 1 the second end position is shown. The pivot axis A and the shift shaft 12 are coaxial.

The primary fixed contact 14U , the primary swivel contact 15U , the primary contact carrier 16 and the bearing tube 18 are each made of solid copper and thus electrically conductive. The primary swivel contact 15U is formed knife-shaped at its free, radially outer end and extends radially to the pivot axis A. The primary fixed contact 14U has a receiving groove 19 ( 7 ) for the primary swivel contact 15U which also extends radially to the pivot axis A and in the 1 to the left and with respect to the pivot axis A clockwise open. The shift shaft 12 and the pedestal 13 consist of insulating material and are therefore not electrically conductive. The bearing tube 18 is at his in the 1 lower end with the socket 13 screwed.

So if the knife-shaped primary fixed contact 14U in the receiving groove 19 is located and thus the primary swivel contact 15U at the primary fixed contact 14U is applied, then they are electrically connected to each other and the switch 10 closed. If, however, the knife-shaped primary fixed contact 14U outside the receiving groove 19 is and thus the primary fixed contact 14U from the primary fixed contact is disconnected, then they are not electrically connected to each other and the switch 10 open.

The primary contact carrier 16 includes a ring 20 and a radially outwardly projecting flange 21 at which the primary swivel contact 15U screwed with its solid, radially inner end. The ring 20 whose axis is coaxial with the pivot axis A, is pivotable about the pivot axis A on the outer peripheral surface of the bearing tube 18 and thus on the shift shaft 12 stored ( 6 ). The primary contact carrier 16 is at its flange 21 with the primary swivel contact 15U and at his ring 20 with the bearing tube 18 electrically connected, so that the primary swivel contact 15U with the bearing tube 18 is electrically connected. On the inner peripheral surface of the ring 20 and the outer peripheral surface of the bearing tube 18 a ring-shaped lamellar contact element is supported 22 springy off ( 6 ), for a safe, durable and good electrical connection between primary contact carrier 16 and bearing tube 18 even when they are moved by panning against each other.

The primary drive mechanism 17 includes a scanner 23 and a connecting rod 24 at one end with the scanner 23 connected is. The scanner 23 is displaceable radially to the pivot axis A on the base 13 stored by being in the 1 lower end in a radial guide groove on the base 13 attached guide block 25 sitting. The connecting rod 24 is at the other end with the primary swivel contact 15U connected by pivoting with the flange 21 of the primary contact carrier 16 connected is. The primary drive mechanism 17 can over the scanner 23 be coupled to a suitable drive source, for example, a pneumatic or hydraulic or electromechanical power cylinder or, as will be described in more detail below, the shift shaft 12 can be.

In the 2 and 3 is a second embodiment of a switch 10 and a second embodiment of a switching device 11 with a switching shaft 12 and this switch 10 shown schematically, wherein the 2 a first switching position of the switch 10 and the switching device 11 and the 3 shows a second switching position. These embodiments are similar to the first embodiments, so that below all the differences are explained in detail. With this switch 10 and this switching device 11 For example, the three phases U, V, W of a three-phase system can be switched.

In these embodiments, the switch comprises 10 additionally two more primary fixed contacts 14V . 14W , two the other primary fixed contacts 14V . 14W assigned further primary swivel contacts 15V . 15W , three secondary fixed contacts 26U . 26V . 26W , three the secondary fixed contacts 26 assigned secondary swivel contacts 27U . 27V . 27W , a secondary contact carrier 28 and a secondary drive mechanism 29 , The other primary fixed contacts 14V . 14W and the secondary fixed contacts 26 are analogous to the primary fixed contact 14U formed, the other primary pivot contacts 15V . 15W and the secondary swing contacts 27 are analogous to the primary swivel contact 15U trained, the secondary contact carrier 28 is analogous to the primary contact carrier 16 trained, and the secondary drive mechanism 29 is analogous to the primary drive mechanism 17 educated. The first primary fixed contact 14U , the first primary swivel contact 15U , the first secondary fixed contact 26U and the first secondary swing contact 27U For example, the first phase U may be assigned, the second primary fixed contact 14V , the second primary swivel contact 15V , the second secondary fixed contact 26V and the second secondary swing contact 27V the second phase V, and the third primary fixed contact 14W , the third primary swivel contact 15W , the third secondary hard contact 26W and the third secondary swing contact 27W the third phase W.

At the pedestal 13 are the other primary fixed contacts 14V . 14W and the secondary fixed contacts 26 attached. The primary fixed contacts 14 are at equal angular intervals of 120 ° with respect to the pivot axis A to the base 13 arranged. The secondary fixed contacts 26 are also at equal angular intervals of 120 ° with respect to the pivot axis A to the base 13 arranged, but at 60 ° to the primary fixed contacts 14 offset; In addition, they lie in a plane that is above the primary fixed contacts 14 lies. Besides, their recording grooves are 19 ' opposite to the grooves 19 the primary fixed contacts 14 aligned, namely in the 1 open in the counterclockwise direction.

Each additional primary swivel contact 15V . 15W and each secondary swing contact 27 is pivotable about the pivot axis A so on the base 13 stored in that it has a first end position in which it at the respectively associated fixed contact 14V . 14W . 26 abuts, and a second end position in which he from this respectively associated fixed contact 14V . 14W . 26 is isolated, can take. In the 2 are the secondary swing contacts 27 in the first end position and the primary swing contacts 15 shown in the second end position. In the 3 are the secondary swing contacts 27 and the primary swivel contacts 15 shown in the first end position.

The primary contact carrier 16 includes two more radially from the ring 20 outwardly projecting flanges 21 to which the other primary swivel contacts 15V . 15W are screwed with their solid, radially inner ends. Consequently, the primary swing contacts 15 over the primary contact carrier 16 electrically connected to each other.

The secondary contact carrier 28 includes as the primary contact carrier 16 a ring 20 ' and three radially outwardly projecting flanges 21 ' to which the secondary swivel contacts 27 are screwed with their solid, radially inner ends. Consequently, the secondary swing contacts 27 via the secondary contact carrier 28 electrically connected to each other. The ring 20 ' whose axis is coaxial with the pivot axis A is like the ring 20 about the pivot axis A pivotally on the outer peripheral surface of the bearing tube 18 and thus on the shift shaft 12 stored ( 6 ), but above the ring 20 , The secondary contact carrier 28 is at his flanges 21 ' with the secondary swivel contacts 27 and at his ring 20 ' with the bearing tube 18 electrically connected, so that the secondary swivel contacts 27 with the bearing tube 18 and therefore over the bearing tube 18 with the primary swivel contacts 15 are electrically connected. The bearing tube 18 can therefore be used as a common derivative or star point for the primary swing contacts 15 and the secondary swing contacts 27 serve. On the inner peripheral surface of the ring 20 ' and the outer peripheral surface of the bearing tube 18 rests like the primary contact carrier 16 another annular lamellar contact element 22 springy off ( 6 ), for a safe, durable and good electrical connection between secondary contact carrier 28 and bearing tube 18 even when they are moved by panning against each other.

The primary swing contacts 15 are at the angular intervals of the primary fixed contacts 14 , in these embodiments, at equal angular intervals of 120 °, on the ring 20 arranged. The secondary fixed contacts 26 are also in the angular intervals of the secondary fixed contacts 26 , in these embodiments, at equal angular intervals of 120 °, on the ring 20 ' arranged, however, in its first end position by 60 ° to the primary pivot contacts 15 placed in their first end position ( 3 ); In addition, they lie in a plane that is above the primary pivot contacts 15 lies.

The secondary drive mechanism 29 includes like the primary drive mechanism 17 a scanner 23 ' and a connecting rod 24 ' at one end with the scanner 23 ' connected is. The scanner 23 ' is displaceable radially to the pivot axis A on the base 13 stored by being in the 2 lower end in a radial guide groove on the base 13 attached guide block 25 ' sitting. The connecting rod 24 ' is at the other end with the second secondary swivel contact 27V , the Indian 2 can not be seen, since it is in the second secondary fixed contact 26V is connected by pivoting with the corresponding flange 21 ' of the secondary contact carrier 28 connected is. The secondary drive mechanism 29 can like the primary drive mechanism 17 over the scanner 23 ' be coupled to a suitable drive source, for example, a pneumatic or hydraulic or electro-mechanical working cylinder or, as will be described in more detail below, the shift shaft 12 can be.

The 2 shows the first switching position of the switch 10 in which the secondary swivel contacts 27 in the first end position and the primary swing contacts 15 in the second end position. Consequently, the primary fixed contacts 14 from each other, from the secondary fixed contacts 26 and the bearing tube 18 electrically isolated or disconnected and the secondary fixed contacts 26 with the bearing tube 18 electrically connected, which can be electrically conductively connected, for example, with a common discharge connection or be.

In this switching position, for example, as described below with reference to 9 will be described in more detail, a continuous current from the currently selected taps of the windings of a three-phase control transformer on the three-phase secondary selector contacts of a selector, the three-phase associated secondary main switch, the secondary fixed contacts 26 , the secondary swing contacts 27 and the secondary contact carrier 28 to the bearing tube 18 while at the same time the three-phase primary selector contacts of the selector can be electrically conductively connected to other taps of the windings corresponding to a desired transmission ratio without electrical load or load-free and / or primary main switches associated with the three phases which are connected to the primary Selector contacts and the primary fixed contacts 14 are connected, can be closed without electrical load or load.

The 3 shows the second switching position of the switch 10 in which the secondary swivel contacts 27 and the primary swing contacts 15 are in the first end position. Consequently, the secondary hard contacts 26 and the primary fixed contacts 14 with the bearing tube 18 electrically connected. Starting from the first switching position of 2 This second switching position is achieved by operating the primary drive mechanism 17 achieved by his scanner 23 in the guide groove of his guide block 25 pushed radially outwards, so that its connecting rod 24 the primary contact carrier 16 in the counterclockwise direction in the 2 and 3 pivots about the pivot axis A.

In this switching position, for example, a short-term current from the currently selected taps on the secondary selector contacts, the secondary main switch and / or parallel to this secondary secondary switch, the secondary fixed contacts 26 , the secondary swing contacts 27 and the secondary contact carrier 28 as well as a stream of the desired, other taps via the primary selector contacts, the primary main switches and / or parallel to these switched primary sub-switches, the primary fixed contacts 14 , the primary swivel contacts 15 and the primary contact carrier 16 to the bearing tube 18 be guided.

A third switching position of the switch 10 can, for example, starting from the second switching position of 3 by actuating the secondary drive mechanism 29 be achieved by his scanner 23 ' in the guide groove of his guide block 25 ' pushed radially outwards, so that its connecting rod 24 ' the secondary contact carrier 28 in the counterclockwise direction in the 2 and 3 pivots about the pivot axis A. In this third switching position, the primary pivot contacts 15 in the first end position and the secondary swing contacts 27 in the second end position. Consequently, the secondary hard contacts 26 from each other, from the primary fixed contacts 14 and the bearing tube 18 electrically isolated or disconnected and the primary fixed contacts 14 with the bearing tube 18 electrically connected.

In this switching position, for example, a continuous current of the now new selected as desired, other taps on the primary selector contacts, the primary main switch, the primary fixed contacts 14 , the primary swivel contacts 15 and the primary contact carrier 16 to the bearing tube 18 be guided, while at the same time the secondary selector contacts of the previously selected taps without electrical load or load-free dissolved or disconnected and optionally with other, corresponding to a desired next gear ratio taps of the windings without electrical load or load-free electrically conductive and / or Secondary main switch can be opened without electrical load or load-free.

A fourth switching position of the switch 10 For example, by such operation of the primary drive mechanism 17 and / or the secondary drive mechanism 29 be achieved that the scanner 23 like in the 2 in the guide groove of the guide block 25 pushed radially inward and the scanner 23 ' in the guide groove of the guide block 25 ' pushed radially outward. In this fourth switching position, the primary pivot contacts 15 and the secondary swing contacts 27 in the second end position. Consequently, the primary fixed contacts 14 and the secondary fixed contacts 26 from each other and from the bearing tube 18 electrically isolated or separated.

In the 4 . 5 and 6 is a third embodiment of a switch 10 and a third embodiment of a switching device 11 with a switching shaft 12 and this switch 10 shown schematically, wherein the 4 a first switching position of the switch 10 and the switching device 11 according to the 2 , the 5 a second switching position corresponding to 3 and the 6 one along the line VI-VI of 5 sectioned sectional view shows. These embodiments are similar to the second embodiments, so that below all the differences are explained in detail.

In these embodiments, the primary drive mechanism comprises 17 In addition, a cam mechanism, which is a cam 30 , the rotation with the shift shaft 12 can and can be connected, and the scanner 23 includes, and includes the secondary drive mechanism 29 in addition a cam gear, which is the cam 30 and the scanner 23 ' includes. Consequently, the shift shaft 12 the drive source of the drive mechanisms 17 . 29 , The cam 30 points to each scanner 23 . 23 ' a curved path 31 . 31 ' on that the assigned scanner 23 . 23 ' slidably receives.
