    Abstract: In view of the requirement of automatic control for vacuum circuit breaker trolly from State Grid, an intelligent device with many features such as automatic switching for the trolly, controlling the forward and reverse rotation, motor locked-rotor protection, remote status display was designed, by using MC68HC908GR8 micro-controller as main control and communication module, two relays as motor control module, and Hall current transformer as sampling motor current. The experimental results show that the controller can do measurement accurately, switch stably and reliably by various function tests with switchgear, EMC experiments, and on-site operation.
            Key words: vacuum circuit breaker; trolly; automatic control unit; Hall current transformer; relay
