Abstract (en)
[origin: WO2018050522A1] The invention relates to a method for switching an on-load tap changer (11) comprising a tap selector (20), which comprises: a plurality of selector fixed contacts comprising a commutation contact (200) which can be connected to an original winding (12) of a regulating transformer (10), and a plurality of stage contacts (201...208) that can be respectively connected to an associated tap of a regulating winding (13) of the regulating transformer; a first selector arm (26) which can optionally contact each selector fixed contact; a second selector arm (36) which can optionally contact each selector fixed contact; a preselector (40) which switches from a first position to a second position and vice versa and can be connected to the regulating winding and the original winding, comprising a first preselector fixed contact (401), a second preselector fixed contact (402), and a third preselector fixed contact, which is connected to the first preselector fixed contact in the first position and to the second preselector fixed contact in the second position; a diverter switch (60) which can be switched from a first position into a second position and vice versa, comprising a first connection (601) which is connected to the first selector arm (26), and a second connection (602) which is connected to the second selector arm (36); and a discharge line (603) which is connected to the first terminal connection in the first position and to the second terminal connection in the second position; where when the preselector is switched, the selector arms are adjusted in such a way that one of the selector arms contacts the commutation contact and the other selector arm does not contact any of the stage contacts, and a switching of the diverter switch begins before the switching of the preselector is completed.
