Definitions

  • the invention relates to a high voltage arrangement with a switching device.
  • a high voltage arrangement is for example from the German patent application DE 102 19 055 known.
  • EP 0 735 637 A2 is a switching device with a grounded, insulating gas filled metal housing known.
  • the local switching device has a first terminal, a second terminal and a third terminal. In various switching positions, the first connection to the second connection and in a second switching position, the first connection to the third connection. In a third switching position, the three connections are unconnected.
  • a gear is provided with a rotating element, via which movable contact parts for generating the various switching positions can be driven.
  • it is provided to arrange on an axially elongated housing each nozzle-like in the radial direction projecting flanges. Such a configuration of a housing is advantageous if, as described in the known arrangement, outdoor bushings are to be used.
  • the invention has for its object to provide a high voltage arrangement, which offers a great deal of flexibility in the assembly of high voltage assembly.
  • the invention provides that the switching device comprises a transmission, whereby the switching position of the switching device can be changed, wherein the switching device in a first switching position connects a first terminal to a second terminal and in a second switching position the first terminal to a third terminal and in a third switching position, the three terminals unconnected, wherein the drive is arranged in the housing on a central axis extending through the housing center of the housing and the drive axis is perpendicular to the central axis and the displacement of one of the electrical contact elements on the central axis and parallel to this.
  • a significant advantage of the invention is that the transmission and the switching device within the housing can be mounted differently, for example, rotated by 180 °, without having to make structural changes to the transmission or to the switching device.
  • the housing is axisymmetric, and the central axis preferably forms an axis of symmetry of the housing.
  • the displacement axis or the displacement of the two electrical contact elements is preferably perpendicular to the drive axle of the drive.
  • the high voltage assembly comprises a housing having a first housing opening and a second housing opening, wherein both the first and the second housing opening are adapted to selectively attach to them a viewing window or a ground contact terminal.
  • the viewing window and the ground contact terminal can be interchanged, so that the high-voltage arrangement can be easily reconfigured.
  • the first housing opening and the second housing opening are opposite each other with respect to the axis of symmetry.
  • the first housing opening and the second housing opening are preferably identical to allow easy replacement of viewing window and ground contact terminal when the gear is to be mounted rotated 180 ° within the housing.
  • the earthing contact terminal forms, for example, the third terminal of the high-voltage arrangement, which can be connected to the first contact by the switching device.
  • the two housing openings and one in one of the two housing openings inserted viewing window are dimensioned and aligned such that through the viewing window through both the position of a first electrical contact element, which can connect the first terminal and the second terminal to each other, as well as the position of a second electrical contact element, the first terminal and the third terminal can connect with each other, is recognizable from the outside.
  • One of the two contact elements forms, for example, a ground contact element and the other of the two contact elements, for example, a separating contact element of the switching device.
  • the switching device comprises a gearbox with two coupling rods, which are pivotable in a predetermined pivoting plane and each move an associated electrical contact element during pivoting, whereby the switching position of the switching device can be changed, wherein the switching device in a first switching position connects a first terminal with a second terminal and in a second switching position the first terminal with a third terminal and in a third switching position unconnected the three terminals that a drive axis of a drive of the high voltage arrangement is arranged perpendicular to the pivot plane of the coupling rods and that the two Coupling rods are mounted such that at least one of them when adjusting the switching position of the switching device by the drive axle region in which the drive axle of the drive, the pivoting plane of the two coupling rods d
  • an advantage of this embodiment of the high voltage arrangement is the fact that the internal structure of the transmission energy-saving switching allows the switching device.
  • the kinematics of the coupling rods namely the movement of the contact elements is positively influenced. Due to the fact that the coupling rods can pass through the drive axle region of the drive, it can be achieved, for example, that the switching-off contact element is moved less than the switching contact element when the switching position of the switching device changes. Starting, for example, from the third switching position, in which both contact elements are turned off and thus each have a sufficient isolation distance to their associated mating contact element, can be avoided that when switching one contact element, the other remaining off contact element is moved synchronously; because such synchronous Mitbessel is not necessary from an electrical point of view, because the distance between the contact element and mating contact element in the off contact element is already sufficient and does not need to be further increased.
  • the deflection movement of the disengaging coupling rod can be significantly smaller than the deflection movement of the engaging coupling rod and thus the contact element remaining switched off is moved less than the switching contact element. Since, due to friction, each drive movement requires drive energy, drive energy is saved due to the reduced movement stroke of the remaining contact element, in comparison to other switching devices in which the switching contact element and the remaining contact element are synchronously coupled or moved with equally large Auslenkh.
  • An advantage of this embodiment of the high-voltage arrangement is that due to the fürschwenkbarkeit or the possibility of divergence of the coupling rods through the drive axle area, both the displacement of one of the electrical contact elements as well the drive of the switching device can be arranged centrally in the housing of the high-voltage arrangement. For example, the displacement of one of the electrical contact elements parallel to the central axis of the housing and the drive axis perpendicular to the central axis, and although still in the middle of the housing, arrange.

  • Dipping the coupling rods can be achieved particularly easily if the drive is indirectly or directly in communication with the first transmission plate and the space between the two transmission plates in the drive axle area remains free for swinging through the coupling rods.
  • the first and the second connecting rod have the same distance from the drive axle in order to ensure that the movement characteristic of the contact elements from the third switching position to the second switching position is identical to the movement characteristic of the contact elements from the third switching position to the first switching position.
  • the drive communicates with the first gear plate to allow it to rotate about the drive axis; the second gear plate is rotated in this case by the two connecting rods with the first gear plate.
  • the second gear plate is preferably connected to a coaxially to the drive axle arranged drive coupling element in connection, so that this is rotated on rotation of the first gear plate and the second gear plate.
  • the drive coupling element is connected at one end to the second transmission plate and at its other end to a first transmission plate of another or second switching device of the high-voltage arrangement.
