Design of a New Kind of Intelligent Controller for Low-Voltage Circuit Breaker

The design of intelligent controller in low-voltage circuit breaker based on the microprocessor DS80C390 was introduced in this paper. Besides possessing the essential three sections of protection functions, the intelligent circuit breaker has the functions of measuring and displaying such parameters as voltage, current, power factor and state of circuit breaker as well as function of pre-warning. The data and control information can be remotely transferred by applying the CAN fieldbus technology. Applying integrated chips, small volume, high reliability, low cost and short period of design were achieved.
