Multiphase circuit breaker system having a short-circuit link

摘要

The circuit breaker system contains a plurality of phase conductors, a circuit breaker having a plurality of breaker poles, and a short-circuit link having a star point and a plurality of link conductors combined at the star point. Each of the phase conductors is electrically conductively connected to in each case one of the breaker poles and each link conductor is electrically conductively connected to in each case one of the phase conductors in each case one of several first disconnectors to which short-circuit current can be applied. In order to avoid expenditure on assembly and downtimes of the circuit breaker system when carrying out simulation experiments with the aid of the short-circuit link, the circuit breaker system contains a second disconnector which, when closed, electrically conductively connects the star point to ground and which is opened when a short-circuit current is applied to the short-circuit current link.
