Electromagnetic operation device

摘要

An electromagnetic operation device, comprising electromagnetic operators 4 each paired with a vacuum valve 1 of each phase of three phases, is equipped with main shafts 2 that can operate independently for each phase and a three-phase connecting shaft 3 that synchronizes the operation of the three phases in accordance with the operation of each main shaft. The rod 44 of the electromagnetic operator 4 is connected with the blade 45 of the main shaft 2 at the fulcrum 46 and the blade 47 of the three-phase connecting shaft 3 is connected with the blade 45 of the main shaft 2 by the linkage 7. The motion of a main shaft 2 that has operated quicker than the others is transmitted to the other main shafts via the three-phase connecting shaft 3 so as to synchronize the operation of the three phases.
