MULTIPHASE CIRCUIT BREAKER SYSTEM HAVING SHORT-CIRCUIT LINK Russian patent published in 2018 - IPC H01H73/00 

FIELD: electrical engineering.

SUBSTANCE: technical result is achieved by the fact that the switch system contains a plurality of phase conductors (L), a circuit breaker having a plurality of poles (GP), and short-circuit link (KSV) having star point (S) and a plurality of link conductors (LK) combined at the star point. Each of the phase conductors (L) is electrically conductively connected the corresponding one of breaker poles (GP) and each link conductor (LK) is electrically conductively connected to the corresponding one of the phase conductors (L) through the corresponding one of several first disconnectors (T1) to which short-circuit current can be applied. Switch system further comprises second disconnector (T2) which, when closed, electrically conductively connects star point (S) to ground (E) and which is opened when a short-circuit current is applied to short-circuit current link (KSV).

EFFECT: technical result is faster operation when testing by the short-circuit simulation method.
