    • The invention relates to a circuit arrangement for switching current from a contact to a thyristor connected in parallel to the contact. In the inventive circuit arrangement ohmic resistances (7, 8, 9, 10) are connected in parallel to the contact (1), whereby each ohmic resistance (7, 8, 9, 10) can be individually disconnected by means of a delayed-opening contact (3, 4, 5, 6) and the disconnection times are staggered. In this manner, it is possible to accomplish stepwise current switching and thus reliably prevent arcing at the contact (1).

    • Snap-action spring device for load-reversing switches of multiple contact switches whose spring can be loaded by a drive. In conventional load-reversing switches, a gear moves a cam disk to and fro between two end positions, so that the contacts which close last during the movement in one direction are the first to open during the reverse movement and vice versa. This rigid sequence of contacts is unsuitable for thyristor load-reversing switches. The invention proposes that the driven element be connected to a coupling element which can rotate in one direction only independently of the direction of rotation of the drive. This permits automatic contact sequence control and precludes switching errors, in a simpler manner.

    • The invention relates to an arrangement in an on-load change-over switch of an on-load tap changer for uninterrupted switch-over of the regulating winding of a transformer. On-load change-over switching is usually accomplished using mechanical switching elements. Burning of contact and contamination of oil are disadvantageous. Furthermore, there are known constructions which use a combination of mechanical switching elements and thyristors for on-load change-over switching. The disadvantage of such arrangements is mainly the too great constructional expenditure for the control elements which are liable to breakdown. According to the invention, the on-load current is supplied to a common output line via a lower winding tap or a higher winding tap of a regulating stage of a regulating winding, and through at least two selector contacts and two permanent contacts whereby the switch-over from the lower to the higher winding tap, and vice versa, is effected via a change-over switch which briefly switches the on-load current to a load relief circuit which is arranged between the root connection of the change-over switch and the common output line. The discharge circuit could comprise, for example, two thyristor circuits, the thyristors of which are connected in antiparallel, one of these thyristor circuits being connected in series with a transition resistor.
