    摘要: A breaker device for interrupting current flowing on a transmission line, the device comprising three electrical branches (B1, B2, B3) connected in parallel, including a main branch (B1) in which the current to be interrupted flows and an auxiliary branch (B2), the main branch comprising at least one semi-conductor breaker cell (CEL1) connected in series with at least one mechanical interrupter/disconnector (Sm), the auxiliary branch (B2) 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 (B2) 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.

    摘要: For application to medium- and high-voltage circuit breakers, the control device makes it possible to actuate opening of the circuit breakers used in the medium- and high-voltage networks very quickly. The spring used in the control device is a spring of the composite type, having a curved C- or Ω-shape. The spring has a stationary first end and a movable second end that is pivotally connected to the end of a lever device, that is itself constrained to rotate with the drive shaft of the control device.
