Abstract
A pivot supporting structure for a circuit breaker and a circuit breaker. The pivot supporting structure comprises: a supporting body having a supporting hole for receiving and pivotally supporting a pivot pin connected to an actuating mechanism of the circuit breaker, wherein at least one strain gauge are mounted to the supporting body for sensing the force acting on the pivot supporting structure by the actuating mechanism. This pivot supporting structure can accurately sense the characteristic force applied, such that the contact force and mechanical characteristics of the circuit breaker can be on-line monitored.

A pivot supporting structure for a circuit breaker, comprising:
- a supporting body having a supporting hole for receiving and pivotally supporting a pivot pin connected to an actuating mechanism of the circuit breaker,
- wherein at least one strain gauge are mounted to the supporting body for sensing the force acting on the pivot supporting structure by the actuating mechanism.
A circuit breaker, comprising:
- an actuating mechanism for actuating a movable contact of the circuit breaker;
- and
- a pivot supporting structure comprising a supporting body having a supporting hole for receiving and pivotally supporting a pivot pin connected to an actuating mechanism of the circuit breaker;
- at least one strain gauge mounted to the supporting body for sensing the force acting on the pivot supporting structure by the actuating mechanism;
- and
- wherein the supporting body of the pivot supporting structure is fixed to a base of the circuit breaker, and the supporting hole of the pivot supporting structure is coupled to a lever of the actuating mechanism via a pin.
