Abstract
The interlock control for a circuit breaker and a disconnector comprises a moving bar for opening or closing the circuit breaker and a displacement rod for displacing a disconnector rod to open or close the disconnector. The moving bar is driven by an arm which is secured to an outlet shaft and which is rotatable in a plane perpendicular to the outlet shaft, and the displacement rod is driven via an L-shaped piece which is movable about an axis that is substantially parallel to the outlet shaft, the arm driving the L-shaped piece during a second opening or closing stage of the circuit breaker via a wheel which is fixed to the arm and which slides in a notch of the L-shaped piece. The outlet shaft makes it possible to achieve interlocking by means of a single control, thereby providing a high level of reliability and of safety.
