Current limiting arrangement has switching point connected in rated current path in series with vacuum switch and provided with device for increasing spark voltage

摘要

The arrangement has a vacuum switch (1) connected in a rated current path and a commutation path in parallel with the rated current path and containing a power electronic switching device (13). A second switching point (2) is connected in the rated current path in series with the vacuum switch and provided with a device (3) for increasing a spark voltage in the form of several mutually isolated plates for dividing the spark into several parts.
