| description | The circuit breaker operating mechanism is characterized in that a lever, a primary lock catch, a secondary lock catch and a jump pin are erected and installed on a rack, a handle is installed on the lever, the lever is connected with an upper connecting rod, the jump pin acts on the primary lock catch and the secondary lock catch which are in linkage for locking and unlocking, and the jump pin, the upper connecting rod, a lower connecting rod and a rotating shaft are sequentially and rotationally connected to form a four-bar mechanism. The moving contact is installed on the rotating shaft and is contacted with and separated from the static contact. The operating mechanism drives the upper connecting rod, the lower connecting rod and the rotating shaft to move through rotation of the lever, the primary lock catch and the secondary lock catch are matched to lock and unlock the jump pin, the main tension spring provides energy storage for movement of the operating mechanism, and finally contact and separation o |
