非接触給電システムの技術開発動向

摘要

Recently, a carriage monorail and battery buses using a non-contact power supply system have been put to practical use. The linear transformer system can feed electricity to moving or rotating equipments without involving abrasion and heavy maintenance. Of course, this system may be applied to railway systems. However, compatibility and interoperability are taken seriously in railway systems, accordingly it may be difficult to make drastic changes in the railway vehicle and infrastructure. In this paper, we report a survey result of domestic and foreign non-contact power supply systems, keeping in view its practical use in railway system.%近年,感電の心配や摩耗がなく,移動体や回転体にエrnネルギ供給の可能な非接触給電技術を用いた電池バスやrn工場内搬送装置の実用化が進んでいる。
