In order to improve the performance of intelligent circuit breaker and its reliability

we utilized the objectoriented technology for smart vacuum circuit breaker physical structure and function（service）based on IEC 61850 standard.The operational status of internal logical node of intelligent breaker was established to integrate the measuring information flow of field parameters

the monitoring information flow of status data and the operating and controlling information flow.According to the characteristic of intelligent breaker status parameters

the IEC 61850 standard repository can be extended based on IEC 62271 standards

and the IED server model was built suitable for intelligent breaker.The model includes the temperature testing of the switch contacts

the detection of vacuum switch motion and the primary circuit parameters testing.Finally

we accomplished the IEC 61850 implemented in the intelligent breaker communication.It is showed that the feasibility of intelligent vacuum breaker status monitoring through the closing test.
