Abstract
In view of situation that existing controller and networking communication of low-voltage breaker adopt user-defined protocol,which has shortcomings of poor reliability and exchangeability in communication,the paper introduced a design scheme of a new type of intelligent controller for low-voltage breaker based on DeviceNet protocol and introduced its design of hardware and software in details.The controller not only has functions of a general controller,but also has DeviceNet fieldbus interface,which can communicate with computers in control center expediently.The experiment result showed that the controller has advantages of reliable running and convenient operation.
