摘　　要：提出了一种基于空气与冰的电阻特性差异实现电力输电网线路与塔架覆冰厚度自动检测的新型覆冰厚度传感器及其检测方法。空气与冰的电阻值具有明显的数值差异,将被检测物体表面空间划分为空气、冰两种具有不同物理特征的区域并将其切割为多层空间,对各分层的电阻值进行检测,并根据其数值差异来综合测定电力输电线路与塔架表面覆冰厚度,从而实现在恶劣的野外工作环境下对电力输电网覆冰厚度变化进行自动连续监测的目的。A novel ice accretion thickness sensor and detection theory based on the difference of the resistance value of air and ice was reported, which can realize automatic detection of the electricity supply network. The resistance value of air and ice has obvious differences, the surface space of object is divided into air area and ice area that are two kinds of area with different resistance value characteristics, which are cut into multi-layer space. The resistance value and temperature of every layer are measured, and the thickness of the ice accretion is determined according to the resistance difference between layers, thus realize the automatic detection of the ice accretion of the electricity supply network in the severe working environment.
