VORRICHTUNG ZUM SCHOTTEN EINES SAMMELSCHIENENRAUMES EINER ELEKTRISCHEN SCHALTZELLE

摘要

The three phase outlets in the bus chamber wall are elongated into one large oblong opening (2, 3, 4). When the circuit breaker is withdrawn this slot is closed by two plates. One is of propeller shape comprising two blades (5, 7) mounted on an annular ring (9). It closes the ends of the slot. The other is a single flap (6) for closing the central section (3) and the hole in the ring (9). The propeller shaped part is linked to an operating rod (8) associated with the circuit breaker trolley. The central flap (6) is driven by a pin attached to the ring (9), and is located on the busbar chamber wall by another pin (12) free to move in a guide slot (11) in the wall.
