Introduction was made to the hardware and software design of a kind of intelligent controller for low-voltage circuit-breakers based on high performance 16-bit processor, DSPIC30F6011A. The three point intersection algorithm was used to calculate the effective values of electrical parameters. The action response time of short circuit current was improved greatly. The intelligent circuit-breaker nut only realized the basic protection functions, but also monitored the field parameter of low-voltage distribution system and regional chain functions were realized with improvement of the system＇s reliability. The circuit-breaker could communicate with the monitoring system through the field bus to meet the requirements of low-voltage distribution system at present.
