电力设备绝缘损伤形式及自修复材料研究进展

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.
