摘要： A mechanism for a multipole circuit breaker with high currents and high electrodynamic strength, comprising a toggle device associated to a trip hook and a switching bar, an opening ratchet cooperating with the hook to perform loading and tripping of the mechanism respectively in the locked or unlocked position of the ratchet. The opening ratchet comprises a disengageable actuator causing self-unlocking of the catch in the presence of a short-circuit current exceeding a calibration threshold defined by a flexible element, said self-unlocking being commanded from a mechanical reaction generated by the electrodynamic compensation effect and causing an ultra-fast rotation of the catch to unlock the opening ratchet before the tripping component operates.

摘要： A closing system for an arc extinguishing chamber of a circuit breaker with high breaking capacity has been developed. The system according to the invention comprises a first duct equipped with a set of filters able to support usual pressures caused by the gases arising from the switching arc, in particular about 10 to 12 bars, and a second duct closed by a valve device enabling direct outlet of the exhaust gases when the pressure exceeds a threshold so as to prevent any explosion of the case. The outer wall of the extinguishing chamber is designed for the circuit breaker housing so as, including in case of opening of the valve device, to direct the gases and to prevent any arc-over on the frame. The valve device comprises a suitable membrane made from polymer, in particular aramide.

摘要： An electrical arc extinguishing chamber designed to be placed facing separable contacts of a switchgear apparatus and to extinguish the arc generated by separation of the contacts comprises two side walls facing one another and a plurality of spaced apart plates arranged between the side walls and secured by the side walls. The side walls have a stratified composite structure with at least two layers. The layers comprise a polyamide fabric impregnated with thermosetting resin. The chamber thus obtained has advantageous breaking strength properties. The edges of the side walls do not present any dielectric weakness points. The chamber is particularly suitable for low-voltage switchgear of high power ratings.

摘要： A device for measuring the wear of the contacts of a switchgear device is described. The switchgear device is of the open circuit breaker type with offset pole-shaft, and the movable contact is mounted on a sliding support. Measurement of the wear of the contacts is based on evaluation of the over-travel of the movable contact in the closed position when the latter slides in its support. This over-travel is determined by measuring the residual rotation of the pole-shaft, preferably by a contact-less magnetic rotation sensor.

摘要： A device for protection against voltage surges comprises a stationary electrode and a movable electrode arranged facing an arc extinguishing chamber. The movable electrode is driven by a mechanisms, by an electromechanical actuator and/or by an electromagnetic circuit. At rest, the movable electrode is situated at a distance from the stationary electrode. When a voltage surge occurs between the electrodes, an arc arises and extends in the chamber in which it is extinguished. If the arc continues, in particular in the case of a follow current of high energy, the movable electrode is driven to a disconnected position moving away from the stationary electrode, which has the effect of lengthening the arc even more in the chamber to facilitate its extinction and perform disconnection of the circuit. A pair of contacts may be associated in series to the electrodes, one of the contacts being stationary and the other being fixedly secured to the movable electrode. A spark gap can also be associated to the electrodes.

摘要： The contact bridge of a molded case circuit breaker is rotatably mounted in a bar by two springs arranged symmetrically from the rotation axis. Each spring is, on the one hand, anchored to the contact bridge, and, on the other hand, anchored to a rod housed in a notch of the bar. The same springs provide contact pressure and slowing-down of opening of the contact bridge at the end of repulsion travel by electrodynamic effect. The contact bridge bears on its edge cam surfaces which, at the end of opening travel, engage the anchoring rods to move them in the notches in the elongation direction of the tension springs. The energy of the contact bridge is thus taken up and stored in the springs causing slowing-down of the contact bridge. The profile of the cams can be chosen to enable reclosing of the contact bridge, this reclosing naturally being delayed by the slowing-down effect at the end of travel. The cam profile can also ensure latching of the contact bridge in the open position.
摘要翻译：模制外壳断路器的接触桥通过从旋转轴对称布置的两个弹簧可旋转地安装在杆中。一方面，每个弹簧锚固在接触桥上，另一方面，固定在杆上设置的杆上。相同的弹簧提供接触压力，并通过电动效应在排斥行程结束时减缓接触桥的开口。接触桥承在其边缘凸轮表面上，其在打开行程结束时接合锚定杆，以使它们在拉伸弹簧的伸长方向上的凹口中移动。因此，接触桥的能量被吸收并存储在弹簧中，导致接触桥的减速。可以选择凸轮轮廓以实现接触桥的重新闭合，这种重合闸自然被行进结束时的减速效应延迟。凸轮轮廓也可以确保接触桥在闭合位置的锁定。
