Definitions

  • the invention relates to a tap changer according to the preamble of the first claim.
  • Such a tap changer is already known from DE 42 37 165 C1.
  • the switching mechanism consists of an elevator carriage and driven part.
  • the elevator carriage is connected to a mechanical contact acting as a pre-selection contact, which can be brought into contact with each of the fixed step contacts and with its free end slides on a contact rail, which in turn is connected to the load discharge via at least one contact resistance and a first vacuum switch .
  • the output part is connected to a trailing mechanical switch contact, which can also be connected to each of the fixed step contacts and in turn is connected to the load discharge via a second vacuum switch.
  • the object of the invention is to provide a tap changer of the generic type which allows high switching powers, ie the guidance of high load currents, and at the same time offers a high level of functional reliability.
  • a particular advantage of the tap changer according to the invention is the fact that the vacuum switch or switches in the switching branch are relieved or relieved by an additional mechanical contact in the stationary state.
  • Figure 3 shows a modified embodiment of the invention.
  • the latter is designed so that two individual contact rail parts KS A and KS B are present, between which the additional fixed contact S o is located.
  • the two contact rail parts KS A , KS B and the additional contact S o are fixed and are fixed with respect to their relative position to one another on the driven part and are moved with it.
  • the function of this embodiment is unchanged, as can be seen from the switching sequence shown in FIG. 4.
