摘要

本文讨论了飞机变流器和电机之间的电缆绝缘问题。重点介绍了对电缆进行的热老化试验，并分析了电容的变化。测试是在用聚酰亚胺和聚四氟乙烯(PTFE)绝缘的三线屏蔽电缆样品上进行的。研究表明，电缆导体间电容与电缆电绝缘老化有关。

May the capacitance of power cables be an aging indicator?

The presented paper concerns the insulation of cables providing the link between the converters and electrical machines in aircraft. It focuses on thermal aging tests performed on cables with the analysis of the capacitance variation. The tests were conducted on samples of a three-wire shielded cable, insulated with polyimide and polytetrafluoroethylene (PTFE). This study shows that the capacitance between the conductors of a cable is correlated with the aging of its electrical insulation.
