摘　　要：提出一种基于电磁感应原理的架空线路绝缘子防(融)冰技术构想方案:在绝缘子外表面涂敷绝缘导热涂料,在绝缘子铁帽表面缠绕高频闭合感应线圈,在绝缘子附近(导线下方)安装一高频电磁波发射装置;启动高频电磁波发射装置向闭合感应线圈发射高频电磁波,使其获得感应电磁能,致使线圈产生感应电流而发热,并通过绝缘导热材料传导到绝缘子表面,从而达到防(融)冰的目的。推导了高频闭合感应线圈所获得的感应电磁能(所能产生的热量)与高频电磁波波长、发射天线半径、闭合感应线圈结构尺寸等各项参数之间的关系,并进行了建模仿真,验证了各片绝缘子都能获得一定的电磁能和方案的有效性。A conceptual solution of insulator deicing based on electromagnetic induction principle is proposed：coats the insulator with insulating and heat-conductive dope and winds its iron cap with high -frequency inductive coils;powers on the high-frequency electromagnetic launcher nearby the insulator（below the transmission line） and transmits high-frequency electromagnetic wave to the closed induction coils;the insulator coating conducts the heat generated by the inductive current in the coil for deicing. The relationship between the electromagnetic energy obtained by the coils（heat generated） and the parameters is deduced,such as electromagnetic wave length,transmission and simulation are carried out,which shows the solution is antenna radius,coil size,etc.,and the modeling valid and each insulator piece obtains a certain amount of electromagnetic energy.
