Definitions

  • the invention relates to a step transformer according to the preamble of claim 1.
  • Step transformers of this type are usually equipped with center changeovers, which can only be actuated when the transformer is switched off. To set the voltage, the transformer must therefore always be switched off.
  • transformers in which a voltage setting can be carried out under load i.e. transformers in which a voltage setting can be carried out under load.
  • the mere replacement of a transformer equipped with a diverter by a transformer that can be regulated under load is of course very complex. Therefore, efforts are being made to replace the existing diverter with a load selector in such transformers. In general, this does not cause too much difficulty for transformers with star point tapping.
  • modified load selectors of a conventional type can now be used to convert the step transformer with center tap. That it is no longer necessary to use two load selectors per phase or one two-pole load selector per phase. It is possible to provide the load selector on the transformer instead of the original diverter without major modifications. However, it is also possible to use a load selector of the attachment type.
  • the step transformer has two winding parts W1, W2, which are provided with three taps 1, 2, 3 and 4, 5, 6 towards the center M.
  • the taps are each connected to a fixed step contact Kl, K2, K3 or K4, K5, K6 of a load selector.
  • the step contacts K1 to K6 are arranged in a circle in the usual way.
  • the load selector has a movable contact system 10; which can be pivoted around the center of the circle from one to the next step contact.
  • the movable contact system has a main contact 11 and two resistance contacts 12 and a sliding contact 13,
  • annular discharge contact 14 which is connected to a two-part annular discharge contact 14, 15.
  • the main contact 11 is directly connected to the sliding contact 13, while the resistance contacts 12 are each connected to the sliding contact 13 with the interposition of the transition resistors 16.
  • the annular discharge contact is - as I said - in two parts, the first part 14 being assigned to the step contacts K1 to K3 and being electrically connected to the tap 4 of the winding part W2 which is located away from the center, while the second part 15 of the discharge contact is the step contacts K4, K5, K6 is assigned and is electrically connected to the tapping 3 of the first winding part W1 lying towards the center M.
  • the lowest voltage setting is present in the position shown in FIG. 1.
  • the current profile goes from tap 1 via the step contact K 1, the main contact 11, the sliding contact 13, the discharge contact 14 to the tap 4.
  • the winding parts lying between the taps are therefore all removed.
  • the movable contact system 10 is moved from the step contact K1 to the step contact K2.
  • the two step contacts Kl and K2 are briefly bridged in the usual way, in that one of the resistance contacts 12 is still in contact with the step contact Kl, while the other resistance contact 12 has already come into contact with the step contact K2 (see also FIG. 2).
  • the change takes place of the movable contact system 10 from the step contact K3 to the step contact K4.
  • the sliding contact 13 also changes from the diverter contact 14 to the diverter contact 15. If the current profile was initially from the tap 3 via the step contact K3 and the diverter contact 14 to the tap 4, the current profile is after the switching operation has been completed from the tap 3 via the diverter contact 15 and the tap contact K4 for tapping 4.
  • This switching step means no change in voltage on the tap transformer.
  • the movable contact system changes from step contact K4 to step contact K5, whereby the winding part lying between taps 4 and 5 is switched on with a further voltage increase.
  • the movable contact system can be moved to the K6 step contact.
  • the discharge contacts 14, 15 lie in a plane below or above the fixed step contacts K1-K6 arranged in a circle, and the movable contacts can be designed as roller bridges.
  • the arrangement is in no way limited to the number of stages shown.
