Title: STEPPING SWITCH ON A CONTROL TRANSFORMER
Abstract:
The invention relates to a stepping switch, which is provided with a preselector, for interruption-free control on a control transformer, wherein the control transformer has one or more main windings and a stepped winding, wherein the stepping switch can be connected between different winding taps of the stepped winding which can each be connected to a load discharge line, and wherein a preselector is provided with a preselector contact by means of which the start or end of the stepped winding can be selectively connected to the end of the main winding. The invention provides a further switch by means of which a damping resistor between the root connection of the preselector contact and the end of the main winding can be switched on.
