Definitions

  • the invention relates to an arrangement for load switching according to the preamble of claim 1, and to an associated method.
  • Such a switching arrangement is known from DE-C 25 20 670.
  • both switch contact pairs can act as main or resistance switch contact pairs depending on the switching direction and thus the contact wear on both switch contact pairs progresses evenly, regardless of whether the corresponding transformer to be switched often with the full load current, which leads to excessive consumption of the Main switching contact pair leads, or at idle, with a very low load current with a correspondingly low erosion of this pair of contacts.
  • a disadvantage of the known circuit is that the single-pole changeover switch, which, depending on the direction of rotation of the drive, makes the function assignment of the switch contact pairs as the main or resistance switch contact pair. switches the entire load current that leads to load dissipation.
  • the object of the invention is to change the known switching arrangement so that only a minimum of switching movements from the energy accumulator must be carried out in the shortest possible time and in rapid succession; the other switching operations should be possible without current and thus be able to take place before or after its dissolution, regardless of the energy store.
  • the step transformer to be switched is provided with tap steps 1, 2, 3;
  • the two load branches are located between two tap stages 2, 3, each of which has two pairs of switch contacts lying in series, on the one hand the contact pair 4.1 in series with the contact pair 7, on the other hand the contact pair 4.2 in series with the contact pair 6.
  • a continuous current contact pair 8, 9 is connected in parallel.
  • a switching resistor 5 is arranged between the contact pairs of each load branch.
  • the two contact pairs 4.1, 4.2 of each load branch, each facing the tap selector, are designed as a common double-pole changeover switch 4; the other two contact pairs 6, 7 facing the load conductor 10 of each load branch are power switching contact pairs which are mechanically coupled to the permanent current contact pairs 8, 9.
  • Steps i) to p) show a further, analog switching step back to the starting position.
  • FIG. 3 Another exemplary arrangement for load switching is shown in FIG. 3.
  • the two individually operable permanent current contact pairs 8, 9 are replaced by a single changeover switch 11, which connects the contacts facing the tap stages 2, 3 in each load branch, acting directly as a bypass with the load lead 10.
  • the changeover switch 11 is mechanically coupled to the other contacts in such a way that the same procedure results.
  • FIG. 4 again shows the corresponding switching sequence when switching to another tap level (steps a-h) and back again (steps i-p).
