摘要： An alternator disconnector circuit-breaker of the invention presents a compact structure. The axes of opening/closure of the change-over first switch (12, 14), of the circuit-breaker second switch (22, 24), and of the disconnector switch (32, 34) are such that an angle of 90° is present between two of them. Actuator means (40) associated with synchronization means (52, 54, 56, 58) make it possible to ensure that each switch is operated in a time-shifted manner by common control means.

摘要： An alternator disconnector circuit-breaker of the invention presents a resistance (30) in series with the circuit-breaker switch (20′); the resistance (30) is of fixed ohmic value that is about 104 times greater than the value of the resistance of the main circuit of the circuit-breaker. By means of this configuration, it is possible to use a vacuum chamber as the circuit-breaker switch (20′), and to dimension the main switch (10), which, de facto, breaks the current even for very high short-circuit currents, under more advantageous conditions.

摘要： A gas blast circuit breaker comprises a cylindrical metal or insulative enclosure filled with pressurized insulative gas, a fixed arc contact and a mobile assembly coupled to an operating member comprising a gas blast cylinder associated with a gas blast nozzle and cooperating with a piston, and a mobile arc contact carried by a tubular member inside the gas blast cylinder. The inside wall of the tubular member comprises a bottleneck whose cross-section is less than the inside cross-section of the tubular member and coaxial therewith. The minimum cross-section of the bottleneck has a diameter less than or equal to the diameter of the inside cross-section of the mobile arc contact and equal to at least 0.75 times the diameter of the inside cross-section of the mobile arc contact. The operation of the circuit breaker is improved by increasing the gas pressure near the mobile arc contact by virtue of a particularly simple and low-cost arrangement.
