- the device for transferring forces disclosed therein has an arrangement with an at least partially flexible guide element with a first leg and a second leg, which are arranged for opposing current flow so as to generate an electromagnetic force and comprises a latchable lever arrangement the electromagnetic force on the one hand to increase the contact pressure force when the contact system is closed and on the other hand in a turn-off operation to support the opening operation of the contact system is available.
- Object of the present invention is to develop a device of the type mentioned, which has a simple structure.
- the housing of the switching device on side walls bearing surfaces for the stationary arrangement of the first leg.

- the housing of the switching device has an inner dimension between a guide surface of a first terminal and a further guide element of a rear housing wall, which is slightly larger than an outer dimension of the support plate such that the support plate within the housing between the guide surface and the further guide element of the housing is slidably guided.
- FIG. 1 shows a three-dimensional schematic view of a device according to the invention in a switching device
- Fig. 2 is a detail view of the embodiment of
- FIG. 1 shows a switching device 1 in the form of a circuit breaker with a three-phase arrangement, as used for example for power distribution in the medium voltage range.
- a pole 2, 3, 4 is provided in each case with a housing 5.
- the housing 5 of the pole 2 of FIG. 1 is shown partially transparent for the sake of better clarity, wherein the housing 5 is typically made of an insulating material, for example epoxy resin or another plastic, around the poles 2, 3 and 4 to isolate each other electrically.
- the pole 2 will be described in more detail below.
- a vacuum interrupter 6 with a arranged in a vacuum-tight housing, figuratively not apparent contact system of a moving contact and a fixed contact for switching or interrupting a run on the switching device 1 current, in particular, for example, in a short circuit after a predetermined time, the switching device 1 for Switching off the part of the power supply network connected to the switching device 1 is provided.
- the moving contact of the contact system of the vacuum interrupter 6 is brought out of the vacuum interrupter 6 in a vacuum-tight manner via a contact pin 7 and mechanically coupled via a drive rod 8 to a drive for initiating a drive movement for opening or closing the contact system, not shown figuratively illustrated contact pressure spring exerts a contact pressure force on the moving contact of the vacuum interrupter in the closed state via the drive rod.
- the drive rod 8 has an insulating element 10 provided with ribs 9 for the electrical decoupling of drive and moving contact connection bolt.
- the BewegCountanInstitutInstitut für Bolzen 7 is electrically connected to a first terminal 11 of the switching device 1 via a flexible conductor element 12 which is fixed contact of the contact system of the vacuum interrupter 6 electrically connected via a fixed contact connection pin to a second terminal 13 of the switching device 1, wherein the first terminal 11 and the second terminal 13 for electrically conductive connection, for example with a
- the flexible conductor element 12 comprises a first leg 14, which is arranged stationarily in the housing 5, in which it rests on bearing surfaces 15 of the pole housing 5, which are better visible in the housing of the pole 4.
- a second leg 16 of the flexible conductor element 12 is electrically conductively connected to the BewegCountan gleichbolzen 7 and guided on a fixed to the BewegCountan gleichbolzen 7 support plate along and held it.
- the first leg 14 and the second leg 16 are arranged in such a way that a current conducted via the switching device 1 flows through the first leg 14 and the second leg 16 in opposite directions, so that an electromagnetic repulsive force between the first leg 14 and the second leg 16 Leg 16 is generated.
- the second leg 16 is guided and held below the support plate 17 along this, so that such electromagnetic repulsive force between the first leg 14 and second leg 16 by the stationary arrangement of the first leg 14 on the bearing surfaces 15 of the housing 5 via the second leg 16 acts on the support plate and thus presses the Bewegumblean gleichbolzen 7 upwards in the embodiment and on the contact system of moving contact and fixed contact of the vacuum interrupter 6 exerts a contact pressure force which supports the contact pressure of the contact pressure spring 9 in the closed state of Needlessys- system or increased.
- the housings 5 of the poles 2, 3 and 4 of the switching device 1 in this case have an inner dimension between side walls 18 and 19, which is slightly larger than an outer dimension of the support plate 17 such that the support plate 17 within the housing 5 between the side walls eighteenth and 19 of the housing 5 of the poles 2, 3 and 4 is slidably guided, so that occurring lateral forces are absorbed in a short-circuit current from the housing 5, in particular not to a deflection of movable Can lead parts such as the Bewegjoran gleichbolzen or the flexible conductor elements. Furthermore, the support plate is guided in addition to the lateral guide on the rear housing wall of the housing 5 and the front of a provided on the first terminal 11 guide member, as explained in more detail below with reference to FIG 2.

- Leg 14 is connected by means of fastening elements 21 to the first terminal 11 electrically conductive.
- the first leg 14 rests on the bearing surfaces 15 of the housing 5 of the switching device 1 and is thus arranged stationarily in the housing 5.
- the insulator 10 of the drive rod 8 can also be seen, as well as fastening elements 22 for fastening the first terminal 11 to the housing 5.
- the first terminal 11 further has a guide surface 23 on its side facing the support plate 17, which guide surface 23 together with a On the rear housing wall of the housing 5 provided further guide member 24 forms a guide of the support plate 17 by the distance between the guide surface 23 and the other guide member is slightly larger than the dimension of the support plate 17, such that here also a sliding guide is made possible , by the analogous to the guide through the side walls 18 and 19 ensures a recording of forces and a deflection of moving parts is effectively suppressed by such forces.
- the arrangement of the first leg 14 and second leg 16 for the opposite current flow is due to the opposing current flow a repulsive electromagnetic force generated between the first leg 14 and the second leg 16, which increases the contact pressure of the contact pressure spring and in particular at a short circuit current occurring leads to a significant increase in the contact pressure, so that in a short-circuit current, the contact system can be kept closed for a controlled time until a Short circuit is located in the power distribution network and then subsequently the contact system of the vacuum interrupter 6 can be opened to a shutdown of the over
