PROBLEM TO BE SOLVED: To provide an operation mechanism of a switch gear capable of improving a switching property of a long gap. SOLUTION: Electromagnetic actuators 18a, 18b are composed of operation rods 26a, 26b jointed to a movable shaft of the switch gear, armatures 20a, 20b pinched by the operation rods 26a, 26b, yokes 19a, 19b forming a flux path, and solenoid coils 23a, 23b, 24a, 24b opening and closing the switch gear. The plurality of electromagnetic actuators 18a, 18b are arrayed in parallel, and respective operation rods 26a, 26b are jointed to each other. COPYRIGHT: (C)2006,JPO&NCIPI
