同轴热敏电缆电容特性的研究

Study on the capacitance property of the coaxial heat sensitive cable

同轴热敏电缆原是基于其具有的NTC热敏电阻特性研制而成的,对其结构、原理进行了介绍。实验中,发现同轴热敏电缆不仅具有良好NTC热敏电阻特性,同时还具有良好的PTC热敏电容特性,针对其具有的电容特性,做了火焰灼烧电容响应及恢复实验、重复性实验、振动和冲击实验。同轴热敏电缆电容特性的发现为其双参数控制提供了新途径。

The coaxial heat sensitive cable is mainly based on its NTC properties of heat sensitive resistance,and its structure and principle are introduced in the article. The fact is discovered that the coaxial heat sensitive cable has not only NTC resistance property but also PTC capacitance property by tests. Tests such as response / recovery time test in flame, Vibration test,and Impact test are explored against its capacitance property. The capacitance property of the coaxial heat sensitive cable is a new path to its double parameters control.
