摘　　要：电力设备绝缘材料在生产、安装、敷设以及服役期间受到各种人为、环境因素的影响,易出现材料本体缺陷、机械损伤以及电气损伤等不同的绝缘损伤形式。自修复材料能通过材料内部分子的物理相互作用或是一定的化学反应识别损伤并对其进行修复。自修复绝缘材料的发展对延长电力设备的使用寿命和维持设备运行稳定性具有重要意义,将有效推动电力物联网和坚强智能电网的发展。该文总结了电力设备绝缘材料的基本缺陷及损伤形式,并归纳综述了可实现绝缘材料自修复功能的方法。Materials of electrical insulation structure in power equipment will inevitably be affected by human and environmental factors during production,installation,laying,and service periods,and are prone to different forms of material damage such as intrinsic defects,mechanical damage,and electrical damage.Ideal self-healing materials are an ideal choice,which can self-identify and repair damage through physical interactions of molecules within the material or certain chemical reactions.The development of self-healing insulation materials is of great significance for extending the service life of power equipment and maintaining the stability of equipment operation,effectively promoting the development of the internet of things in power systems and strong smart grids.This paper summarizes the basic defects and damage forms of insulation materials in power equipment,and introduces the methods that can achieve the self-healing function of insulation materials.
