Development of the Ground Coil for Practical Use by the Combined Propulsion, Levitation and Guidance System

摘要

It is required to reduce the cost of ground coils used in the superconducting maglev system given their large quantity in use. They should also have high reliability and improved workability at installation. Therefore, we developed a ground coil for practical use by the combined Propulsion, Levitation and Guidance system (PLG coil) to reduce the construction cost of the superconducting maglev line. After repeating calculation and examination, we made some PLG coils on trial, and examined them to confirm their initial performance. As a result, we confirmed that their initial insulation strength was satisfactory and they were able to be put into practical use.
