Abstract:This paper designed a kind of DC motor driven device system based on large power driving chip BTM7752G as core power apparatus. The system was used for power system switchgear intelligent control. The system adopted ATmega128 as main control chip to accomplish electric switchgear needed intelligent real-time action instruction analysis, mechanism device position state test and data transmission treatment, remote control and real-time state display etc intelligent functions treatment. BTM7752G chip has built-in over voltage and over current protect functions in favor of complicated electromagnetic environment developing use and stability of functions. The apparatus model selection design plan provided by the system not only makes for new and old equipment intelligent reformation and upgrading plant preinstallation and maintenance simplification, but also can provide reference for common electric equipment electric execution mechanism in leading of intelligent electrical functions.
Key words:intelligent grid; H-bridge; electric actuating mechanism; BTM7752G chip
