Abstract
A breaker device for interrupting current flowing on a transmission line, the device comprising three electrical branches (B, B, B) connected in parallel, including a main branch (B) in which the current to be interrupted flows and an auxiliary branch (B), the main branch comprising at least one semi-conductor breaker cell (CEL) connected in series with at least one mechanical interrupter/disconnector (S), the auxiliary branch (B) comprising at least one thyristor, the breaker device further comprising a control circuit (CM) suitable for interrupting a current that flows in the main branch. Once the current is interrupted in the semi-conductor element of the breaker cell of the main branch, the control circuit acts to command the thyristor of the auxiliary branch (B) to be put into a conductive state whenever a current flowing in the voltage limiter(s) reaches the value of the current that is flowing in the transmission line.
