Definitions

  • the invention relates to an electrical high-voltage gas pressure switch with a contact arrangement which has at least one fixed and one movable contact piece and with a device for equalizing the electrical field.
  • the present invention has for its object to improve the switching properties of high-voltage gas pressure switches of the type mentioned.
  • the object is achieved in that the device for equalizing the electric field has two differently drivable field electrodes.
  • an optimal field equalization in the area of the switching path can be achieved at any time by a suitable drive of the field electrodes.
  • the field electrodes can be moved by a pivotably mounted two-armed lever.
  • the use of a two-armed lever means that only one field electrode is directly coupled to the drive device or can be driven by a separate energy store. A different movement of the two field electrodes with respect to one another can also be achieved in a simple manner in this way.
  • the field electrodes are arranged axially on the same side of the switching path.
  • the two field electrodes can be arranged and controlled with respect to one another in such a way that simple field control is possible. Due to the controllable spatial position of the two field electrodes in relation to one another, a variable spatial contour is generated during a switching process, which brings about very good field uniformity.
  • An advantageous embodiment of the invention can be that the field electrodes can be driven in opposite directions to one another.
  • the field electrodes are arranged coaxially with one another and concentrically.
  • Another advantageous embodiment of the invention can be that the first field electrode is annular and the second field electrode is designed as an open cap.
  • the special shape of the field electrodes enables the formation of the desired spatial contour with small masses to be accelerated.
  • FIG. 1 schematically show an example of an embodiment of the high-voltage gas pressure switch according to the invention.
  • FIG. 1 shows an axial section through a high-voltage compressed gas switch designed according to the invention, the switched-on state being shown.
  • FIG. 2 shows an axial section through a high-voltage compressed gas switch designed according to the invention, a dynamic state between the switched-on state and the switched-off state being shown.
  • FIG. 3 shows an axial section through a high-voltage gas pressure switch designed according to the invention, the switch-off state being shown.
  • the high-voltage gas switch has a contact arrangement 1, 2, 3, which is part of the interrupter unit of the high-voltage gas switch.
  • the contact arrangement has a fixed pair of contacts 1, 2 and a movable bridging contact piece 3.
  • the top bridging contact piece 3 is firmly connected to a compression cylinder 4 and can be driven axially with the latter via a drive 5. According to FIG. 1, the bridging contact piece 3 connects both fixed contacts 1, 2 in the switched-on state. According to FIG. 3, the bridged contact piece 3 is arranged outside the switching path lying between the fixed contacts 1, 2 in the switched-off state.
  • the high-voltage gas pressure switch has a device for equalizing the electrical field.
  • Said device has two field electrodes 6, 7 which are movable in opposite directions to one another. Both electrodes 6, 7 are articulated on a fixedly pivoted two-armed lever 8 and can be moved in opposite directions by this.
  • the tension spring 9 forms the drive for the field electrodes 6, 7 during the switch-off movement. In the state represented by FIG. 1, the tension spring 9 is shown in the tensioned state. In the switched-on state, the compression piston 4 forms a stop for the second field electrode 7.
  • the second field electrode 7 initially detaches from the compression cylinder 4. In this state, the first ring-shaped field electrode 6 contributes significantly to the uniformization of the electrical field.
