| Abstract: | Based on symmetrical analysis theory,the stator current of motor is decompounded into positive-sequence current,negative sequence current and zero-sequence current to distinguish the running state and fault type of the motor according to their magnitude of current.The technology of INTEL80C196KB MCU is applied to design and fulfill a new kind of micro-processor protective device for asynchronous motor.The device has perfect protective functions,unfailing performance,steady operation and easy attendance.The criterion of protection,the hardware structure and the protection algorithm are introduced. |
