摘　　要：利用同面多点电容感应技术,设计了一种实时测量输电线路覆冰厚度的传感器.传感器基于电容感应技术,通过测量模拟输电导线周围不同位置金属电极的电容值变化,并对电容值进行分析与计算,得出模拟导线上的覆冰厚度.通过对同面多个金属导线电极电场、电容的理论分析、仿真,以及低温下对系统的冰冻试验,验证了传感器在监测输电线路覆冰厚度的可行性.Using multi-point coplanar capacitance sensing technology, we designed a kind of real-time simulation of on-line monitoring sensor for transmission lines ice thickness. The sensor uses capacitance induction cladding ice thickness, which analoging the capacitance change of the metal electrode around transmission line, and stimulating the ice thickness for wires. Through the simulation and analysis of electric field, capacitor for the surface with multiple metal wire electrode, and testing the system under the low freezing temperature, we verify the feasibility of this sensor on-ling monitoring ice thickness for transmission lines.
