| 内容記述 | The superconducting magnet system for the JT-60SA consists of 18 toroidal field coils (TFC), the central solenoid (CS) comprising four electrically independent stacked modules, and six plasma equilibrium field coils (EFC). The voltage including fre-quency is applied to the CS module by the power supply in the op-erating conditions. It is possible to induce an inhomogeneous voltage distribution in the coil by causing resonance phenomenon, and to damage the insulation between conductors in the coils. Based on the previous studies, the resonance characteristics and the voltage dis-tribution between the conductors were evaluated considering the in-fluence of structures (ground resistance, CS structure, TFC case, and EFC cover). As a result, it can be concluded that the influence of resonance phenomenon, and the ground resistance on the voltage between the conductors in the CS module is negligible small under the operating conditions. These analyzed results become the funda-mental data to evaluate the electric stability of the coils and to pro-tect coil systems. | |||||
