In order to improve the operation safety and reliability of intelligent circuit breaker

this paper first introduce a new type of intelligent circuit breaker mechanical properties on-line monitoring and state evaluation technology of working architecture. And then concrete analysis and illustrates the principle of on-line monitoring which is related to intelligent circuit breaker mechanical properties

such as closing coil current and the energy storage electric current

dynamic contact travel-time characteristic and the auxiliary contacts and so on. Next

this paper provides an effective intelligent circuit breaker state evaluation method

which can get equipment failure information from the monitoring data and waveform analysis

and the collected data can make the corresponding fault diagnosis

and improve the safety and reliability of the intelligent circuit breaker operation.
