Definitions

  • the invention relates to an electrodynamic drive, especially for high voltage switching devices, the one by two coils which can be alternately fed by a voltage source having actuatable armature, which one to be driven Switching contact of a switching device is actuated by the Anchor in the course of a switching process on the one hand a first Auxiliary contact arrangement, which is driving him coil of the voltage source separates and on the other hand, a second Auxiliary contact arrangement is actuated, which for a subsequent switching process to be activated coil ready for use.
  • An electrodynamic drive for electrical switching devices goes with respect to the operation of the driven Switching contact of the electrical switching device by a of two alternately powered by a voltage source Coils operable anchor, for example from the DE 43 04 921 C1. Through this electrodynamic drive Although it is ensured that a by the electric Switch to be executed safely, but it runs is not guaranteed that the electrodynamic drive after a switching process without time delay immediately is ready for the subsequent switching operation.
  • the disadvantage is the known electro-dynamic drive also that, starting from the fact that increasingly as Voltage source a capacitor bank is used as it does, among other things, the drive device for a DC switch according to DE 38 41 592 A1 provides, the Operational readiness of electrical switching devices and thus is also limited by high voltage switching devices. The is especially the case because the current flow is instantaneous not interrupted after completion of a switching operation will, what with unnecessary discharge of the capacitors connected is.
  • a switching device has a electrodynamic drive with two from a voltage source alternately feedable coils. Furthermore, over one Anchor of the electrodynamic drive a first Auxiliary contact arrangement and a second auxiliary contact arrangement actuated, by means of which a switching of the voltage source between the alternately fed coils.
  • a movable switching contact causes a connection or disconnection the first and the second auxiliary contact arrangement.
  • the movable switch contact is arranged by means of the armature Movable stop elements.
  • the invention is therefore based on the object, a to create electrodynamic drive that is not just a ensures rapid switching of the auxiliary contact arrangements, but also a reliable long-lasting design represents that only a small additional space on the Electrodynamic drive required.
  • this is an electrodynamic Drive according to the preamble of claim 1 characterized achieved that actuated by the anchor Auxiliary contact arrangements two each on the inner circumference of Coil arranged sliding contacts have.
  • auxiliary contact arrangements actuatable by the armature two each on the inner circumference of Coils arranged sliding contacts, so can on the Use of separately driven auxiliary contact arrangements be waived. This will be the mass to be accelerated of the anchor by the movable contacts of the Auxiliary contact arrangement no longer charged additionally. There is also a hitting and the associated Shaking the entire drive to operate a movable switching contact not necessary.
  • the sliding contacts are each protected inside the coils and arranged hardly require additional space.
  • An advantageous embodiment may provide that the by the anchor closable sliding contacts in dependence from the position of the anchor with this one current path form.
  • the sliding contacts inside the coils should advantageously have a length which corresponds to the axial length of Ankers corresponds as well as an inlet area for a trouble-free running in of the armature in the coils. deviant Of course, this height of the sliding contacts also a lower height are selected, but then the sliding contacts arranged on the inner circumference of the coils to be arranged on the inlet side for the anchor. The height The sliding contacts will eventually but also by a Safe guiding of the armature within the coils is determined.
  • An activation of the respective, after a movement of the anchor from one to the other coil for a subsequent one Switching operation made ready coil can at the according to the invention electrodynamic drive in dependence from the arrangement of the coils and the sliding contacts of the first and second auxiliary contact arrangement then take place when the corresponding sliding contact is closed by the armature.
  • connection of the first sliding contact the first auxiliary contact arrangement with the voltage source via a switch associated with the switch operation and according to the connection of the switch-on associated Coil over a the switch-on associated Switch.
  • the invention is based on two embodiments a schematic drawing explained in more detail.
  • FIG. 1 and 2 there is the electrodynamic Drive from two alternately powered by a voltage source 1 Coils 2, 3, wherein as a voltage source 1, a capacitor bank is used as well as from the anchor 4, which can be actuated by the coils 2, 3 and via the shift rod 5 with the switching contact, not shown a High voltage switching device is connected. It is the Coil 2 the switch-on in the direction of arrow 18 and the coil 3 the switch-off in the direction of arrow 19th assigned. At the inner periphery of the coil 2 is a first of two sliding contacts 6, 7 existing auxiliary contact arrangement and on the inner circumference of the coil 3, a second also consisting of two sliding contacts 9, 10 auxiliary contact arrangement.
  • Figures 1 and 2 corresponds to the height of the sliding contacts 6, 7 and 9, 10, although the length of the armature 4, but the effects intended by the invention may then also be achieved when the acceleration of the armature 4 at his sliding into the other coil 2, 3 so big is that through its kinetic energy a safe ending the switching process is ensured and thus by interpretation the sliding contacts 6, 7 and 9, 10, in particular with respect a shorter length, already a premature interruption of the sliding contacts 6, 7 or 9, 10 and the Anchor 4 closed circuit can be done, so before the armature 4 leaves the respective coil 2 or 3.
  • the electrodynamic drive according to FIG. 3 corresponds to FIG essential to that of Figure 1 and 2, but in contrast to the electrodynamic drive according to Figure 1 and 2 is here by a modified circuit arrangement of the coils 2, 3 and the sliding contacts 6, 7 and 9, 10 of the first and second Auxiliary contact arrangement in cooperation with the input and Switching off associated switches 13, 15 and the Voltage source 1 in the form of a capacitor battery discharging the capacitor bank on a switching operation reduces a minimum and at the same time the electrodynamic Drive ready for a subsequent switching operation made.
