A closing device and a circuit breaker with the closing device. The closing device comprises a chamber, a closing drive mechanism (11), a volume-variable component (7), a driver (9), and a closing handle (2), in which the closing drive mechanism (11) and the volume-variable component (7) are set in the chamber, and the driver (9) is configured in the volume-variable component (7). The volume-variable component (7) is configured to increase or decrease the volume under the control of the driver (9). The closing drive mechanism (11) is configured to transfer the force generated by the increased volume of the volume-variable component (7) to the closing handle (2). The closing device possesses the advantages of simple configuration, convenient operation and low cost.

Disclosed is a circuit breaker having a cam rotation delaying function employed to block current, the circuit breaker performing a charging operation and a charting operation, the circuit breaker including a closing spring having one end portion rotatably coupled to each of plates, a driving lever rotatably installed at each of the plates and connected to another end portion of the closing spring so as to be rotated responsive to compression and extension of the closing spring, a cam rotatably installed at each of the plates and configured to press the driving lever for rotation, a link mechanism having a plurality of links rotatably installed at each of the plates and connected to the driving lever for operation, a movable contact rotatably installed at a side of each of the plates and contactable with a terminal by an operation of the link mechanism, and a cam delaying mechanism installed at each of the plates and configured to attenuate a rotational force of the cam due to a restoring force of the closing spring, whereby an excessive rotation of the cam can be prevented by the cam delaying mechanism so as to allow stable and complete toggling operation of the link mechanism and a smooth restoring operation of the closing spring, thereby providing more stable operation of the circuit breaker.
摘要:
The present invention relates to a switch device for controlling electrical equipment. Such a switch device comprises a body piece (15), a sliding member (14) and contact surfaces controlled by the sliding member (14), means for latching the sliding member (14) into a closed/open position of the switch and for unlatching the sliding member (14) from said positions, a spring-arming plate (11) and switch actuator springs (10). The invention is implemented by making a slot (33) into the sliding member (14) that controls the second movable set of contact surfaces in the switch and adapting compatible interlock means (34) to the housing or body piece (15) of the switch, said interlock means serving to inhibit the movement of said sliding member (14) by virtue of partially entering the slot (33) made into the sliding member (14). Additionally, the spring-arming plate (11) is provided with a projection (32) capable of covering the slot (33) made into the sliding member (14) and thus preventing the interlock means (34) from inhibiting the movement of the sliding member (14) when the switch is being opened or closed. The switch device is also provided with another set of springs (31) for storing the mechanical energy required for a remote-controlled operation.
