AI Technical Summary

Technical Problem

When an existing circuit breaker experiences an internal fault, the state of the opening and closing handles does not match the actual position of the moving contact, leading to misjudgment by operators and affecting maintenance safety.

Method used

An electrical switching device is adopted, which, through the cooperation of the trigger component and the switching switch, realizes real-time feedback of the moving contact position. Independent of the traditional handle indication mechanism, it accurately reflects the actual opening and closing status of the circuit breaker by utilizing the contact state between the trigger part and the contact.

Benefits of technology

It ensures accurate feedback of the circuit breaker's true on/off status even in the event of an internal fault, improving maintenance safety. It also enables synchronous monitoring and switching of multiple signals through multiple triggering units and transfer switches, thereby improving detection efficiency and applicability.

Abstract

The application relates to the technical field of circuit breakers, in particular to an electrical conversion device and a circuit breaker, which comprises a triggering assembly and a conversion switch, the conversion switch comprises a contact, the triggering assembly comprises a triggering part, the triggering assembly can move relative to the conversion switch, and the triggering assembly can move to the triggering part to abut against the contact. The structure is independent of a traditional handle indication mechanism, when internal faults of the circuit breaker cause the handle state to be inconsistent with the actual position of the moving contact, the real on-off state of the conversion switch can still be accurately fed back through the contact state of the triggering part and the contact, and the safety hidden danger of maintenance caused by misjudgment of the on-off state of the circuit breaker by an operator is fundamentally solved.
