Research on Intelligent Vacuum Circuit Breaker Controller based on Embedded Network Control System

An intelligent releaser with embedded network control function is introduced. And the field bus technology, embedded technology, Ethernet technology and intelligent protection control technology are integrated and applied to the actual products. Based on the front edge of the world´s intelligent electric appliance, the mining vacuum circuit breaker (VCB) of low voltage and large current, which has protective and communication function, has been developed. Moreover, the intelligent protection and control function, network communication and monitor function are implemented by adding the intelligent control module and adopting embedded system and TCP/IP protocol. The system covers the main functions, such as, the protection of short circuit, over-voltage, under voltage, overload and earthing, the real-time communication between Ethernet and terminal computer, the display about the current and voltage of circuit and faults information, the historical data review and print. In order to increase the efficiency, realize the monitoring on-line for remote distance, the intelligent VCB based on the network, communication, openness and compatibility has been developed
