摘要

本文报道了不同厚度的卡普顿H型薄膜的试验和测量结果。测量的量是电容、耗散系数、表面电阻率和体积电阻率。测试变量为电压、温度、频率和压力。电绝缘材料的退化主要是由于高能质子、电子和空间等离子体的相互作用。此外,当航天器面对太阳或遮挡太阳时,由于航天器所承受的极端温度而引起的热循环带来了退化。测量的绝缘材料的性能是体积电阻率、表面电阻率、电容和耗散系数。体积电阻率用于间接表示绝缘材料的均匀性;材料的处理或检测影响绝缘材料质量的导电杂质。它常被用作各种类型的含水率,机械连续性和劣化的间接测量。表面电阻率用于指示在任何时候碰巧在样品表面上的污染程度。它常被用作衡量吸湿和污染物在表面沉积(1)和变质,影响材料绝缘性能。电容用来表示电介质的特性,当电介质表面之间存在电位差时,它允许存储分离的电荷。电容或介电常数的变化表明材料的整体分子性质的变化。耗散系数用于表示交流功率损耗。耗散系数的变化是绝缘性能稳定性的量度,而耗散系数的值是在规定使用条件下绝缘性能质量的量度。

Measurement of Degradation Properties of Dielectric Materials Used on Spacecraft Power Systems
This paper reports the results of tests and measurements made on Kapton type H films of varying thicknesses. The quantities measured are capacitance, dissipation factor, surface resistivity and volume resistivity. The test variables are voltage, temperature, frequency and pressure. The electrical insulating materials suffer degradation primarily due to the interaction of high energy protons, electrons and space plasma. Furthermore, the degradation is brought about by the thermal cycling due to the extreme temperatures to which the spacecraft is subjected when the spacecraft is facing the sun or eclipsed from the sun. The properties of the insulating materials targeted for measurement are Volume Resistivity, Surface Resistivity, Capacitance and Dissipation factor. The volume resistivity is used to indicate, indirectly, the uniformity of an insulating; material either with regard to processing or to detect conductive impurities which affect the quality of the insulating material. It is often used as an indirect measure of moisture content, mechanical continuity and deterioration of various types. The surface resistivity is used to indicate the level of the contamination that happens to be on the surface of the sample at any time. It is often used as a measure of moisture absorption and contaminant deposition on the surface (1) and deterioration, which affect the materials insulating properties. The capacitance is used to indicate the property of a dielectric which permits the storage of electrically separated charges when potential difference exists between the dielectric surfaces. The change in capacitance or dielectric constant indicates the changes in the bulk molecular properties of the material. The dissipation factor is used to indicate the A. C. power loss. The change in dissipation factor is a measure of the stability of the insulating properties, where as the value of the dissipation factor is a measure of the quality of the insulating properties under specified service conditions.
