The invention provides a light-operated modularization intelligent vacuum switch with the phase-selecting function, comprising an intelligent phase-selecting controller low-potential unit, a high-potential unit, a power driving unit, a multi-way energy-acquiring operating power system, a permanent magnet actuating mechanism, a vacuum arc extinguishing chamber, an outer insulating system, and the like. A DSP signal processor with high performance and flexible control technique are adopted to rapidly and accurately judge the optimum switching phase of the switch for reliable operation; an optical control interface is adopted to realize high-pressure and low-pressure isolation, simplify the insulating structure and ensure strong anti-jamming ability; a novel permanent magnet actuating mechanism is adopted to ensure simple structure, flexible control and high reliability; and a novel reliable power source scheme with a multi-way energy-acquiring operating power system for acquiring energy by current, voltage and low potential is adopted. According to the requirement, series-connected and parallel-connected building block combination can be carried out on the light-operated modularization intelligent vacuum switch with the phase-selecting switch so as to realize the intelligent vacuum switch with higher voltage grade.
