要約(英語): High-speed spring-operated mechanism that enables 2-cycle interruption was developed by improving the trip control unit and the link mechanism that connects the interrupter. This mechanism had almost the same composition as a conventional 3-cycle interruption GCB, and we optimized the mechanism to achieve 2-cycle interruption. The solenoid was optimally designed by using a coupled analysis of a nonlinear magnetic field analysis with finite elements model and a dynamic analysis with a kinematic model. We used these analyses to investigate the core material, the number of coil turns, and the stroke of the solenoid. We also calculated the dynamic characteristics of the GCB with the spring operated mechanism in order to satisfy the objective time of opening contact, and the lever of the trip control unit and the lever of the link mechanism were improved. A prototype GCB, which was built based on the above analyses, demonstrated sufficient performance.
