Definitions

  • the invention relates to a tap changer for uninterrupted switching between winding taps of a tapped transformer according to the preamble of the first claim.
  • a tap changer which has a total of four vacuum interrupters per phase.
  • a vacuum interrupter as the main contact and in each case a further vacuum interrupter, are provided in series connection with a transfer resistor, as a resistance contact.
  • the main contact of the disconnecting side is first opened, then closes the resistor contact the receiving side, so that between the two stages n and n + 1 through the switching resistors limited compensating current flows.
  • the previously closed resistance contact has opened the disconnecting side, then closes the main contact of the receiving side, so that the entire load current from the new winding tapping n + 1 leads to the load dissipation; the switching is completed.
  • the vacuum interrupter of the switched load branch carries the continuous current in steady state operation.
  • the object of the invention is therefore to provide a tap changer of the type mentioned above, which allows the management of high continuous currents without additional mechanical permanent contacts.
  • This object is achieved by a tap changer having the features of the first claim.
  • the subclaims relate to advantageous developments of the invention.
  • the general inventive idea is to divide the continuous current to all acting as the main contact switching elements of both load branches and next to the at least one switching element in the current leading load branch also - at least one switching element in the non-load current - already existing, but in the prior art functionless Load branch in the continuous current to include.
  • the object of the invention is achieved without more switching elements or larger sized switching elements would be required.
  • a first load branch is provided in which a vacuum interrupter MSV1 acting as a main contact and, in parallel thereto, a crossover resistor R1 and a vacuum interrupter TTV1 acting as a resistance contact are located.
  • the second load branch has, quite analogously, a vacuum interrupter MSV2 and, in parallel with this, another reversing resistor R2 and a vacuum interrupter TTV2.
  • a first mechanical change-over contact MTF1 is provided in the first load branch, through which the side of the vacuum interrupter not connected to the load discharge line L
  • a second mechanical changeover contact MTF2 is furthermore provided in the second load branch, by means of which the side of the vacuum interrupter MSV2 not connected to the load lead L can also be selectively connected to the previous tap n of the tap winding or to the new winding tap n + 1.
  • mechanical contacts constructed identically and / or combined into a single module.
  • the invention is not limited to the use of vacuum interrupters as switching elements.
  • tap changer with mechanical contacts or semiconductor switches as switching elements are possible; the advantages of the invention apply to such tap changers as well.
