摘要

Improvements in connection arrangements for switching under load without interruption in stepped transformers of the type in which each selector arm of the stepped switch has been assigned at least one load switch, characterized in that the vacuum switches provided as load switches they are connected with their input pole directly and/or indirectly through impedances with the selected selector arms and with their output pole in direct connection with a single circuit breaker contact switch so that, by connecting the power circuit in step by step of the selector arms with their, or with their assigned vacuum switches, is switched through both selector arms with their vacuum switches assigned in the other selector arm and its vacuum switch.
