    摘要： A circuit breaker having means for quickly opening a pair of contacts, a U-shaped flux board which surrounds the conductors that have contacts attached to the end portions thereof, so that the electromagnetic repulsive force produced by the electric current that flows through the opposing conductors in opposite directions relative to each other, will be added to the operation of the contact-opening means. The circuit breaker of the invention is further equipped with arc shielding members surrounding the contacts, so that the arc established across the contacts will not stretch to the conductors in the vicinities of the contacts, and so that the arcing voltage is greatly increased.

    摘要： The present invention relates to a circuit breaker comprising a pair of contactors each comprising a rigid conductor with a contact secured thereon, wherein at least one of the contactors is also provided with an electrically conductive projection secured on the rigid conductor in proximity to the contact, the contact and the projection having their peripheries surrounded by a high resistivity arc shield of a resistivity higher than the rigid conductors. An arc extinguishing plate assembly is also provided to cool and extinguish an arc drawn across the gap between the contacts. With this arrangement, the arc is confined and has its voltage raised by the effects of the arc shield, and the size of the foot of the arc is limited such that it does not spread to the surface of the conductor in the vicinity of the contact. Further, the foot of the arc is caused to shift from the contact to the projection, substantially preventing wear of the contact and further extending the length of the arc to more effectively cool and extinguish the arc.

    摘要翻译： 本发明涉及一种断路器，其包括一对接触器，每个接触器包括固定在其上的接触件的刚性导体，其中至少一个接触器还设有固定在靠近触头的刚性导体上的导电突起， 接触和突起具有由高电阻率高于刚性导体的高电阻率电弧屏蔽包围的外围。 还提供灭弧板组件以冷却和熄灭穿过接触件之间的间隙的弧。 通过这种布置，电弧被限制并且其电压由电弧屏蔽的作用而升高，并且电弧脚的尺寸受到限制，使得其不会在接触附近扩散到导体的表面 。 此外，使电弧的脚从接触件移动到突出部，从而基本上防止接触件的磨损并进一步延长电弧长度以更有效地冷却和熄灭电弧。

    摘要： A circuit interrupter which comprises, in a compartment defined in an electrically insulating housing, a pair of separable contacts defining, when separated, an arcing region therebetween, and an operating mechanism, including a tripping unit and an operating handle, for opening and closing the separable contacts. The housing which includes an electrically insulating bottom wall has a gas exhaust passage having an inlet opening in the inner surface of the housing. The inlet of the gas exhaust passage is located in the bottom wall at a position effective for exhausting an arced gas generated in the arcing region without contacting the operating mechanism.
