CIRCUIT BREAKER COMPRISING A DEVICE FOR INSERTING A RESISTOR INTO A POWER LINE

摘要

The invention relates to a circuit breaker (10) for a high-voltage power line, comprising at least one cutoff chamber (12) with dual contact motion, a member (24) for driving the simultaneous and opposite motion of the contacts of the cutoff chamber, a device (28) for inserting a resistor into the power line, comprising two contacts (36, 38) capable of being placed in contact with one another, characterized in that each contact (36, 38) of the insertion device (28) is connected to the driving member (24) such that the driving member (24) drives the contacts (36, 38) of the insertion device simultaneously with the driving of the contacts (18, 20) of the cutoff chamber (12) only during a closing phase of the circuit breaker (10).
