Abstract
This paper introduces a new vacuum load - breaking switch with main and auxiliary circuit
which is of lower current chopping level
higher transferring current. It can be mainly used for load control and short- circuit pro-tection in three - phase ring circuits or in the terminal distribution system and industrial devices at urban districts. In ad-dition
the combinations with such load - breaking switch are specially applicable to transformer protections.
