    Abstract:A new type of intelligent recolser controller installed on the outdoor rod is developed, which is mainly composed of microcontroller of Intel 87C196KC-20 and CPLD devices. This controller integrates all the functions of measuring, controlling, protection, fault diagnosis, communication, remote-controlled operation and self-power devices with infra-red remote control devices as a unit. The controller applies the distributed structure, field concentration line and intelligent technology to seal up the synthetic servomechanisms such as the microcomputer-based protection and measuring devices in the second stage of the mini out-door transformer substation, which are distributed on the outdoor circuit switches on the spot and formed as a whole . Therefore ,this technology can transform a large number of ordinary homemade SF6circuit beaker and vacuum circuit breaker into intelligent circuit recloser, thus replacing the expensive imported automatic circuit recolser .

     

    Key words: 80C196KC; intelligent recloser controller; alternating current sampling; on-line real-time detection
