In order to achieve the intelligent operation of 126 kV high voltage vacuum circuit breaker, and meet the requirement of circuit breaker opening and closing speed, a new kind of circuit breaker opening and closing motor operating mechanism and control system was proposed. Combined with the load charac-teristic of 126 kV high voltage vacuum circuit breaker, and based on the analysis of surface-mount, dovetail groove table type, linear embedded type and type V inline four kinds of motor rotor, the design project of multi double table stick embedded type stator and the rotor permanent magnet motor were pro-posed, and then the control device with digital signal processor as the core was designed. Online experi-ment of 126 kV high voltage vacuum circuit breaker was conducted. Results show that adopting the above operation mechanism and control system satisfies the opening and closing speed demands indicator of 126 kV high voltage vacuum circuit breaker and the closing time has a good stability.
