Design of Intelligent AC Contactor

Article Preview

Abstract:

Aiming at the problem of high energy consuming and failure rate on traditional AC contactor, the implement method of intelligent AC contactor is presented. The smart structures concept is introduced into the domain of AC contactor and the microcontroller C8051F040 is used as the control core. The intelligent AC contactor is a comprehensive system which assembles data acquisition and control, fault self-diagnosis and protection Function, etc. DC operation and on-line monitoring of the running state is also realized. Experiments show that the system has characteristics of low cost , accurate indication for running state and fault location, good protecting function, completely eliminating the noise and vibration operation, good performance in energy-saving , etc.
