This paper analyzes the current situation of intelligent switchgear in the case of medium voltage

on the guiding ideology of integrated design and integrity test

an intelligent switchgear and integration of intelligent components are designed

introduces the implementation methods of integrity test as well as the functional verification of intelligent unit. The intelligent switchgear is integrated by the design of primary and secondary equipment. It is the first equipment in China

that based on IEC 61850 protocol and the digital instructions of GOOSE

to operate circuit breakers and earthing switch

and the type test has been completed. Simultaneously

the intelligent comparison test has also been completed

and test status in real time over the network protocol to upload record in the background has been achieved.
