The capacitive method is considered to be a suitable icing-detection technology, but the lack of fundamental parameters restricts the development of icing-detection sensors. In this paper, an artificial icing laboratory, a capacitive sensor, and some simulation conductors have been designed for obtaining the artificial icing samples. Subsequently, the same characteristic values of artificial icing have been measured by an LCR device, under a selected frequency. This research found that the value of the icing dielectric constant closely correlated with its density, internal sublayer, and the test temperature. Finally, a fitting formula has been presented for calculating the relative dielectric constant, which may provide some important reference value for the design of icing-detection sensors.
电容法被认为是一种合适的结冰检测技术，但缺乏基本参数限制了结冰检测传感器的发展。本文设计了一个人工结冰实验室、一个电容传感器和一些模拟导体，以获得人工结冰样本。随后，在选定的频率下，使用 LCR 设备测量了具有相同特征值的人工结冰样本。研究发现，结冰的介电常数值与其密度、内部亚层和测试温度密切相关。最后，提出了一个计算相对介电常数的拟合公式，这可能为结冰检测传感器的设计提供一些重要的参考价值。
