摘要： This invention discloses a low-voltage circuit breaker with a capability of tripping quickly. Its main feature is that at least one of the side faces of the contact device provides an open flange which has an internal through hole, and the bottom of a rotating shaft disposed on the bottom part provides a stressed member. The stressed member receives the over-pressure airflow escaping from the open flange of the contact device to generate a force. The force is passed to the activating member by the rotating shaft and is magnified, then hits the latch quickly and makes a trip. An intermediate step is bypassed due to the force produced earlier, the force which is produced by the electromagnetism part in the heat energy and electromagnetic system, so that the low-voltage breaker can open quickly and reduces opening time greatly and improve the breaking capability.
摘要翻译： 本发明公开了一种具有快速跳闸能力的低压断路器。 其主要特征在于，接触装置的至少一个侧面提供具有内部通孔的开口凸缘，并且设置在底部的旋转轴的底部提供受压构件。 受压构件接收从接触装置的打开法兰逸出的过压气流以产生力。 力通过旋转轴传递到激活构件并被放大，然后快速撞击闩锁并跳闸。 由于较早产生的力，由电磁部件在热能和电磁系统中产生的力，旁路中间步骤，使得低压断路器可以快速打开并大大减少开启时间并提高断路能力。
