An intelligent protection and monitoring system for high voltage switchgear based on CAN bus is introduced. Based on Intel 87C196KC, a 16-bit industrial-grade single-chip microcomputer, the application of field bus and intelligent technology integrates protection, measurement, control, telecontrol and fault diagnosis Automation functions scattered in place on the switchgear.In order to improve the system’s real-time and reliability, the use of twisted pair as the communication medium CAN bus as a communication network connecting the switchgear, constitute a fully distributed structure.The actual operation results show , The system has the advantages of high reliability, real-time, anti-interference ability, low cost.
