- the invention relates to the field of high-performance switch technology, in particular to a switching device for switching high electrical currents and voltages according to the preamble of claim 1.
- Such a switching device is, for example, a generator switch which has a similar switch pole for each of three phases.
- a switch pole is designed as a metal-encapsulated switch and has an insulating gas-filled quenching chamber in which the nominal current and power current contacts of the associated phase are located.
- Such a switch pole also has a rotatable axis, which serves to transmit a force from earth potential to a high-voltage potential present in the arcing chamber. With such a force, the nominal current and Power contacts brought together or separated to switch the respective phase on or off.
- the switch poles each have a bottom flange that is at ground potential and is attached to a pole frame of a pole frame of the generator switch.
- the rotatable axes protrude so far from the base flanges that they can be driven below the pole frame table, ie on the side of the pole frame table facing away from the switch poles.
- Each of the rotatable axes is connected by means of two levers and a holder under the pole frame table to a shift linkage also located under the pole frame table.
- This shift linkage comprises a rod composed of several partial rods and a tab. At one of its ends, the shift linkage is connected to a drive rod of a hydraulic spring-loaded drive by means of the tab in such a way that a translational movement of the drive rod is converted into a rotation of the rotatable axis by the shift linkage and the two levers and the holder.
- the drive is arranged laterally next to the pole frame, the drive rod being at least approximately in an imaginary axial extension of the shift linkage, which allows a movement of the drive rod to the shift linkage to be transmitted as directly as possible.

- the drive can be arranged in such a way that the longitudinal axis of the drive rod lies in a second plane, which is parallel to the said first plane and different from this first plane. This makes it possible to adapt the switching device flexibly to structural conditions.
- the transmission comprises a first and a second rocker arm and a shaft which connects the rocker arms to one another, the first shift linkage being connected to the shaft by the first rocker arm and the second shift linkage being connected to the shaft by the second rocker arm, and the shaft is rotatably supported.

- the lever lengths of the first and second rocker arms are of the same size. In this way, forces and lever geometries, such as are used in a switching device considered to be state of the art, can be largely retained, whereby identical parts can be used. This allows an extremely cost-effective implementation of a switch according to the invention.
- the switching device has a pole frame with a pole frame table
- the drive essentially Lichen is arranged on a side of the pole frame table facing away from the at least one switch pole.
- the pole frame table is arranged substantially perpendicular to the rotatable axis. In this way, the drive can be arranged within the pole frame and the installation space required by the switching device can be minimized.
- a significant advantage is obtained if, in the case of three switch poles, each with a lever system, the transmission and the lever systems are connected to the first shift linkage in the order of transmission, lever system, lever system, lever system.
- movement of the first shift linkage on all these lever systems causes either a compressive force or a tensile force.
- the same force then acts in the same manner on all rotatable rods of the switch poles during a switching operation with great accuracy at the same time.
- identical parts can be used for the switching device according to the invention, which makes the production of the switching device considerably less expensive.

- FIGS . 1 and 2 are considered in more detail.
- Moving the drive rod 24 of the drive 2 into the drive 2 causes the three switch poles 1, 1 ' , 1 '' and thus the generator switch to be switched off as a result:

- the movement of the partial rods 13, 13 ' , 13 " leads, as described above, to a movement of the angle levers 27, 27 ' , 27 " , which in turn causes a movement of the curved levers 26, 26 ' , 26 " .
- the curved levers 26, 26 ' , 26 '' then exert a force on the brackets 25, 25 ' , 25 '' , which leads to a rotation of the rotatable axes 8, 8 ' , 8 '' .

- the described numerous rotatable connections between the elements of the switching device can for example be designed as bolt connections.
- the lever lengths L and L ' can also be selected in different sizes if the operational requirements so require. For example, if a drive 2 is to be fitted into a switching device, which has a different stroke of the drive rod 24 or a different force during the switching process than was originally intended for the switching device.
- the angle ⁇ and the angle ⁇ ' in the switched-off state have exactly the negative values as in the switched-on state.
- the positions of the first rocker arm 14 and the second rocker arm 20 are then arranged symmetrically with respect to the straight line G and the straight line G ′ in the switched-on and switched-off state. If the operational requirements make it necessary, other arrangements can also be implemented in which the angles ⁇ and ⁇ ' need not have this symmetry.
- angles ß and ß ' need not be chosen to be the same size. Different angles ß and ß ' can be realized. A structure can also be designed such that the angles ex and ⁇ are of different sizes. In such a way, adaptations of the speed-time profile realized in the switching device to changed operating requirements are very easily possible.
- the angle ⁇ does not have to be chosen so large that the lever arm of the first rocker arm 14 is parallel to a straight line which runs through the positions P2 and P4. If operational requirements make it necessary, other angles ß can also be chosen become.

- the lever length L of the first rocker arm 14 does not have to be exactly as large as the distance between the position P2 and the position P4. Even in such a case, positions P1, P2, P3 and P4 do not form a parallelogram.
- a parallelogram is advantageously formed from the positions P1, P2, P3 and P4, it being essential that the positions P3 and P4 represent two points on the longitudinal axis S of the essentially straight part of the first shift linkage.
- connection between the transmission 15 and the first shift linkage 11 is arranged approximately at one end of the first shift linkage 11. This has the advantage that the same force acts in the same way on all rotatable rods 8, 8 ' , 8 ''of the switch poles 1, 1 ' , 1 " during a switching operation with great accuracy at the same time.
