Definitions

  • the invention relates to a disconnector for switchgear, in particular for traction current systems with commutation devices.
  • circuit breakers and circuit breakers which are designed for a high switching speed, work with spring-loaded actuators and complicated special solutions for the unlocking mechanisms. Apart from their complexity, these are also not fast enough for the intended field of application for railway power plants with electronic commutation devices, in which a fast disconnection of a damaged route exit and possibly a fast restart are necessary. A considerable part of the entire switching process must already be used for unlocking.
  • Switching devices for self-switches and current limiting switches with a separate drive device, contact arrangement and separate switch-on device are also known with an electrodynamic drive, so-called Thomson drive, see e.g. DE-A 36 42 282.
  • the Thomson drive works with a coil and an opposite disc made of conductive material, in which when the coil is excited, e.g. through a capacitor discharge, a current is induced. The opposing currents exert a force on the disk which is connected to a contact. The force is very quick.
  • a separate unlocking mechanism can be dispensed with if necessary.
  • the invention is based on the object of realizing a fast disconnector with a low moving mass, without an unlocking system when disconnecting, and a locking device which is as wear-free and very fast as possible after the disconnection.
  • the catching device In the event of an immediate, very rapid return movement of the contact plate, the catching device is thus fully operational again in order to securely lock the moving parts.
  • FIG. 1 shows the disconnector according to the invention, the two contact plates 1 being connected in parallel.
  • the electrical connection to a connector 3 is established via contact lamellae 2.
  • the electrical connection is made from the connector 4 via the contact blades 5 to the contact plates 1, so that the current path is established in the direction of the arrow and thus a contact bridge is formed.
  • the winding 6 is excited via a capacitor discharge device, not shown, so that the two contact plates 1 are repelled very quickly in opposite directions in the axial direction until the iron disks 7, which are firmly connected to the contact plates 1, abut the permanent-magnet capture devices.
  • the permanent magnetic capture device advantageously consists of a permanent magnet 8, which is provided with an unlocking winding 13 and is connected to the housing 12 via a damping buffer 9 and the damping disk 10.
  • the winding 6 is arranged in a winding support which is arranged between the connecting pieces 3 and 4.
  • the connectors 3 and 4 are advantageously cast together with the winding 6.
  • the moving mass essentially the contact plate 1 and the iron disk 7 and part of the contact pressure spring 11, are braked via the damping buffer 9 and the damping disk 10.
  • the contact pressure spring 11 is used with a suitable spring preload, which is selected so that on the one hand it ensures the necessary contact pressing force of the contact plate 1 when the disconnector is closed and on the other hand enables the iron disk 7 to be securely locked on the permanent magnet 8 when the disconnector is open.
  • the contact pressure spring 11 is supported on the housing 12, which is screwed to the connectors 3 and 4.
  • the lock is released to close the circuit breaker by means of a short current surge in the unlocking winding 13, which is arranged within the permanent magnet 8, whereby the holding force of the permanent magnet 8 is partially compensated, so that the spring force of the contact pressure spring 11 moves the contact plate 1 again in the direction of the connecting pieces 3 and 4 and thus closes the disconnector again.
  • the simple switching path creates a double opening distance.
  • the contact plate does not require any stranded wires.
  • the mode of operation is such that a capacitor discharge takes place via the windings 22 and 23 lying in series and thus the contact plates 1 are repelled, are then caught by the means described in FIG. 1 and remain securely locked.
  • the winding 6 or the windings 22 and 23 are designed in a rectangular or circular shape in FIG. 1 and FIG.
  • a reaction-free design of the disconnector is achieved by the counter-movement of the contact plates, i.e. that no forces can act externally.
  • the contact separation takes place very quickly and without an unlocking mechanism.
  • the locking in the open state takes place without mechanical locking parts and is therefore also very fast.
