摘要

本文介绍了为实现交流- 50hz 25kV电气化铁路与医院安装在铁路隧道上的非常敏感的医疗设备之间的电磁兼容而提出的修正措施。拟议的修正行动是基于敏感设备将要安装的区域的地板屏蔽。为了验证该解决方案的正确性,开发了一个简化的电磁模型,并通过一些测量验证了现有铁路在尽可能相似的条件下运行。最后,由于实际条件是在导电土中,因此将有限元技术应用于最终的性能计算。

Measuring, modelling and correction actions for EMC assessment between high speed railway and medical equipment
This paper presents the correction actions proposed to achieve the Electromagnetic Compatibility between AC-50Hz 25kV electrified railway and the very sensitive medical equipment to be installed in a hospital over the railway tunnel. The proposed correction action is based on the floor-shielding of the area where the sensitive equipment will be installed. In order to validate the correctness of the solution, a simplified electromagnetic model had been developed and verified with some measurements, over existing railways operating in as similar as possible conditions. Finally, as the real conditions will be in a conductive soil, FEM techniques had been applied to the final performance calculus.
