本文通过对试验结果的分析,讨论了PTC陶瓷的老化机理,提出在居里温度以上的温度下进行预老化来提高元件稳定性的方法及进行深入研究的设想。
In this paper, the aging mechanism of PTC ceramics is discussed through the analysis of the test results. The methods of improving the stability of the components by pre-aging at a temperature above the Curie temperature are proposed and the idea of further research is put forward.
