| 内容記述 | In order to realize the DC 1 MV power supply system for ITER neutral beam injector (NBI) and NB test facility (NBTF), insulation technologies in oil, gas, vacuum and with water have been developed. To supply cooling water and high-temperature water, mechanical and electrical properties of fiber reinforce plastic (FRP) with water absorption was clarified. The mock-up of FRP tube was fabricated and pressure tightness and voltage capability was confirmed. As for high-temperature water supply to the plasma grid, the water resistivity up to 180 oC was experimentally measured and the high-temperature water channel was successfully designed. Based on those developments, manufacturing and installation for the power supply components for the NBTF/MITICA has been progressed and completed. Finally, to verify the voltage holding capability of the DC 1 MV power supply component, high-voltage test has been started by filling SF6 gas inside the components. That was the first high-voltage test in the NBTF/MITICA power supply under the assembled configuration with all components procured by Japan. As an initial test, high-voltage of DC 1.2 MV was applied on the DC generators and DC filter. As a result, stable voltage holding without breakdown for 1 hour was successfully confirmed. | |||||
