Capacitor short-circuiting in a high voltage converter

摘要

A short-circuiting arrangement for capacitors of a high voltage converter are provided, the capacitors each having two connection terminals, the arrangement including a short-circuiting wire configured to be moved along while in sliding contact with the connection terminals and including a short-circuiting section with electrically conductive material connected to a ground potential and a probing section with electrically conductive material and a voltage evaluating unit electrically connected to the short-circuit section and the probing section and configured to detect, as the probing section and short-circuiting section are connected to the respective connection terminals, the voltage across the capacitor, compare the voltage with a discharge threshold and halt or move the short-circuiting wire based on the detected voltage.
