Abstract: Example embodiments of the present disclosure relate to an adjusting mechanism of a circuit breaker and a corresponding circuit breaker. The adjusting mechanism comprising an operating rod, a transmitting rod, an adjusting block, a bracket and an adjusting bolt. The operating rod is configured to operate a moving contact of the circuit breaker via a contact spring arranged between the operating rod and the moving contact. The transmitting rod is pivotally coupled to the operating rod and configured to drive the operating rod to move towards or away from a stationary contact of the circuit breaker. The adjusting block is pivotally coupled to the transmitting rod at a position different from the operating rod and comprising a thread hole. The bracket comprises a first supporting element and a second supporting element spaced from the first supporting element along a first direction, each of the first supporting element and the second supporting element comprising a through hole extending along the first direction. The adjusting bolt extends through the through hole of the first supporting element, the thread hole of the adjusting block, and the through hole of the second supporting element sequentially along the first direction, the adjusting bolt comprising an external thread engaging with the thread hole, such that when the adjusting bolt is actuated to rotate about its axis, the adjusting block slides along the first direction between the first supporting element and the second supporting element. According to embodiments of the present disclosure, a stroke of the contact spring can be adjusted in a convenient and precise manner.

Abstract: Embodiments of the present disclosure relate to a switch device, comprising: a first three-position switch; a second three-position switch disposed below the first three-position switch; a circuit breaker disposed between the first three-position switch and the second three-position switch. A first interlock unit is disposed above the circuit breaker and connected to the circuit breaker and the first three-position switch, and configured to block a manual operation of the first three-position switch in a closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the first three-position switch is manually operated in an open state of the circuit breaker. A second interlock unit is disposed below the circuit breaker and connected to the circuit breaker and the second three-position switch, and is configured to block a manual operation of the second three-position switch in the closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the second three-position switch is manually operated in the open state of the circuit breaker.
