Definitions

  • Earthing switch 8WL6144-1A for AC 25 kV traction current systems Siemens AG known from "Product Information / Version 1.2.0 / No. A6Z00029955871” from 2013 on page 3 , is a grounding switch for railway power plants having a first main contact and a movable second main contact, wherein the movable second main contact for producing an air gap from the first main contact is movable away.
  • the earthing switches themselves are differentiated according to the standard with regard to their short-circuit breaking category.
  • the earthing switch 8WL6144-1A is a grounding switch, which is only closed by design and thus produces a grounded condition, if the catenary was previously switched off, secured against reconnection and checked for absence of voltage. These measures prevent the earthing switch from switching to a short circuit - which would damage or destroy it.
  • Earthing switches which are used for AC and DC traction power supply and are to be connected to a live catenary, must, in contrast to the known 8WL6144-1A earthing switch, be short-circuit proof. These switches are characterized today primarily by the fact that the switching blade enters the contact at a high speed and thus takes place in connection with the pre-ignition an entry into the contact at low instantaneous value of the current. Examples are z. B. switches of the series FES 3-20-1 B Fa. Driescher.
  • the object of the invention is to provide a suitable for a multiple short-circuit closing earthing switch in a railway power plant, which can be produced inexpensively.
  • the earthing switch is comparatively simple in design, uses the same platform concept for existing disconnectors and earthing switches and is inexpensive to manufacture. In operation, the earthing switch is particularly low maintenance because it is not damaged or destroyed during a short-circuit closing (in emergency situations).
  • the pre-ignition arrangement is arranged above the main contacts. This is advantageous because a protection of the main contacts is ensured because the main contacts are not in the range of thermal buoyancy of the arc column occurring. This ensures via the minimum principle of the arc, that its bases always on the appropriate, provided for this purpose tips Vorzeündan ever.
  • the pre-ignition arrangement has a pre-ignition device for each main contact.
  • Another advantage is that when replacing the Abbrandmaschine no readjustment of the entire Vorzündanowski must be done, which saves time and costs in maintenance. Furthermore, the technical availability of the catenary system is increased.
  • This material is powder metallurgically by reaction times;
  • CEP DISCOP high-performance copper materials from Compound Extrusion Products GmbH in Freiberg are known (application brochure 09/09).
  • the use of this refractory material is advantageous because it reduces the frequency of maintenance of the consumable elements.
  • the subject of the present invention is a method for grounding a part of a traction current system by means of a grounding switch according to one of the preceding claims, comprising the steps according to claim 12.
  • the same advantages arise analogously to the method according to the invention as described above for the earthing switch according to the invention.
  • FIG. 1a is the earthing switch 1 is open, so that an air gap between the main contacts 3,4 and the Vorzünd Anlagennern 5.6 is formed.
  • the earthing switch 1 is turned off in this state.
  • An existing arc typically causes an associated circuit breaker (not shown) to detect the short circuit and quickly shut down.
  • an existing arc between the pre-ignition 5.6 is already deleted before the earthing switch 1 in Figure 1c shown closed state of the main contacts 3,4 reached.
  • An induced by the arc wear is So to expect only in the field of Vorzünd Anlagenner 5.6, so that after a multiple stress by Kurz practitionerscigenen the earthing switch 1, only the Vorzünd Anlagenner must be replaced, which can be comparatively inexpensive and fast.
  • One of the substations 35 has a data processing center 15 and is set up to exchange measurement data on the state of the electric traction current network and of the feed sections with the other substations 4 via communication lines 33.
  • the earthing switch 39 according to the invention offers a comparatively simply constructed solution which is inexpensive to manufacture and requires little maintenance.
