摘要： An arc extinguishing chamber for an electrical switchgear device, notably a circuit breaker or a current limiting unit, comprises an almost tightly sealed case made of gas-producing insulating material to house separable contacts with electrodynamic repulsion. The movable contact, in the shape of a bridge, appreciably follows the internal configuration of the case playing the role of a piston arranged on both sides of a first compartment generating pressure due to the action of the arc, and a second compartment communicating with the first via a minimal clearance J. The pressure in the second compartment is lower than that in the first compartment. Magnetic circuits can be arranged to accelerate the movable contact to the open position.

摘要： An electrical switchgear apparatus comprises a fixed frame, a circuit breaker movable in the fixed frame between a plugged-out position and a plugged-in position, a reversible plug-in and plug-out mechanism of the circuit breaker, a movable means for detecting an indexed position of the mechanism or of the circuit breaker, linked to a first electrical switch, and a movable means for detecting an indexed position (open or closed) of the main contact means of the circuit breaker linked to a second electrical switch. Each of the two switches comprises an input, a first output and a switching means able to take a first position in which it connects the input of the switch electrically to the first output of the switch, the switching means being kinematically linked to the corresponding detecting means, in such a way that the switching means is in its first position if and only if the corresponding detecting means is in its active position. The output of one of the switches is connected to the input of the other switch. A state indicating device is thus achieved with an input terminal, a first output terminal and means designed to electrically connect the input terminal and the first output terminal if and only if the main contact means and the switchgear apparatus are simultaneously in their indexed position.

摘要： The device comprises two power supply terminals, a local control terminal and remote control and presence detection terminals. It can operate in fully autonomous manner, the power supply terminals being connected to a voltage supply source by means of a local control switch, closing of which causes excitation of a coil of the electro-magnet. It can also operate in conjunction with a communication module. In this case, the terminals are permanently supplied by the source, the local control terminal is connected to one of the power supply terminals by a local control switch and the remote control and presence detection terminals are connected to the module. The device automatically detects the presence of the module and causes excitation of the coil if the supply voltage is sufficient and if a control signal is applied to it either by the local control switch or by the module.

摘要： An auxiliary trip device for a circuit breaker which includes an electromechanical actuating device and an energy storage system. The electromechanical actuating device includes a coil housed in a sheath which has a central bore containing a plunger fixed to a push-rod, and a fixed core spaced apart from the plunger, via a first spring. The push-rod is slidable within the bore to actuate a latch device of the energy storage system, which in turn releases a blade which is cooperable with a trip bar of the circuit breaker on which the auxiliary trip device is placed. The blade is biased by a second spring which releases and stores energy greater than released and stored energy of the first spring.

摘要： The device compares a voltage representative of the supply voltage of the electromagnet with two distinct inrush thresholds and a drop-out threshold. As soon as this voltage reaches one of the inrush thresholds, the device commands switching to an inrush phase of preset duration. The first inrush threshold is representative of a voltage of about 40 to 50% of the rated supply voltage of the electromagnet, whereas the second inrush threshold is representative of 70 to 85% of this voltage. The same control device can thus be used with both an under-voltage release and a shunt release or for a circuit breaker closing electromagnet.
摘要翻译： 该装置将代表电磁体的电源电压的电压与两个不同的突入阈值和辍学阈值进行比较。 一旦该电压达到其中一个浪涌阈值，器件将命令切换到预设持续时间的浪涌阶段。 第一个浪涌阈值代表电磁铁额定电源电压的约40至50％的电压，而第二个涌入阈值代表该电压的70至85％。 因此，相同的控制装置可以同时使用欠压释放和分流释放或断路器闭合电磁体。

摘要： A breaking device for a low voltage circuit breaker comprises in each pole a switching bar, a pair of stationary contacts connected to the connection terminals, a double-break rotary contact extending in a housing of the bar, and two arc chutes disposed on each side of the bar. Two contact pressure springs ensure elastic positioning of the rotary contact along the longitudinal direction of the pole.

摘要： The trip bar is sub-divided into a first actuating part associated to the trip rod of the actuator and a second actuating part operating in conjunction with the indicating device. A mechanical coupling link is arranged between the two actuating parts being adjustable between a coupled position and a disengaged position. An operating lever performs locking of the second actuating part in the active position to keep the fault information on the indicating device, whereas the first actuating part returns automatically to the inactive position when said mechanical link is in the disengaged position.
