超导磁悬浮系统需要大量的接地线圈，将需要在室外使用很长一段时间。因此，在接地线圈运行过程中，必须确保有效的维护。我们使用局部放电测量作为评估推进线圈绝缘性能的一种方法。局部放电是在推进线圈模具树脂绝缘内部的空隙中发生的一种微小的介电击穿现象。我们知道，当局部放电发生时，会发射宽带电磁波。在这样的工程背景下，对以局部放电为重点的绝缘诊断方法进行了验证。局部放电可以作为预测推进线圈绝缘失效的物理指标。在本文中，我们开发了一个局部放电试样来评估绝缘性能。采用局部放电试验试样进行了试验，并利用射电干涉仪系统组成了局部放电检测装置。
Superconducting Maglev systems require a huge number of ground coils will be required for outdoor use over an extended period. Therefore, it is necessary to secure efficient maintenance during the operation of ground coils. We use partial discharges measurement as a method for evaluating the insulation performance of propulsion coils. Partial discharge is a small dielectric breakdown phenomenon that occurs in the void inside mold resin insulation of the propulsion coil. It is known that broadband electromagnetic waves are emitted when partial discharge occurs. Under such an engineering background, insulation diagnosis methods focusing on partial discharge were verified. Partial discharge can be used as physical indicator to predict insulation failure of the propulsion coils. In this paper, we developed a partial discharge test specimen to evaluate insulation performance. A test using a partial discharge test specimen was performed, we composed configuration capable of detecting a partial discharge using radio interferometer system.
