1811 マグネットクラッチ式交直電源切替器の開発(電力給電システム1,SS2:メンテナンス,コストダウン,第18回交通・物流部門大会(TRANSLOG2009)) 1811 Development of magnet clutch type exchange AC/DC switching unit

The exchange AC/DC switching unit currently used at Kuroiso Station in Tohoku line has adopted the drive system by the friction clutch as the conversion mechanism part. However, the asbestos material is used for the clutch friction plate, and the spare item cannot be produced newly in the future. Then, the exchange AC/DC switching unit with the magnet clutch that did not use asbestos was developed. The performance confirmation of the prototype was examined in the factory, and it was confirmed that the prototype operated in actually using it without trouble.
