    Abstract: Introduction was made to a kind of intelligent dual power supply switching in three-phase 220 V power supply system. This method mainly coordinated the automatic bus transfer equipment with the contactor to realize the intelligent switching of power supply, analyzed the electrical circuit diagram and contrasted the advantages of the pure single contactor with those of the contactor combined with a relay. Its feasibility and reliability are confirmed through the actual installation and test. And it is finally used in water cooling system of Cuba Sancti Spiritus substation static var compensator project (SVC).
    Key words: dual power supply switching; contactor; automatic bus transfer equipment
