摘要

本文的实验结果表明，与UL-1446[1]中常用的通过击穿电压的下降特性来评价相容性的方法相比，采用介电法或介电分析法可以监测和表征绝缘材料在密封加热条件下化学老化过程的规律，具有更高的灵敏度、效率和分辨率。发现了利用介电法加速与功能因素相关的绝缘系统老化试验的新前景。

A new approach to compatibility of magnet wire and varnish using dielectrometry

This paper presents an experimental results which show that the regular pattern of chemical aging process of insulating materials under sealed heating condition can be monitored and characterized by dielectrometry or dielectric analysis with higher degree of sensitivity, efficiency and resolution in comparision with the usual method in which the compatibility is assessed by the drooping characteristic of breakdown voltage according to UL-1446 [1]. It is also found a prediction of new prospect that may be feasible to accelerate the aging test of an insulation system associated with functional factors by dielectrometry.
