Abstract
This article reviews the current status of microstructure and electrical characteristics of zinc oxide surge arresters.Zinc oxide valve plates have superior non-linear voltage-current characteristics and energy absorption capabili-ties,making them the core components of metal oxide surge arresters in power systems.Consequently,the overvoltage protection level of metal oxide surge arresters depends on the quality of the electrical characteristics of zinc oxide valve plates,which directly determines the insulation level and manufacturing costs of the power grid equipment.With the rapid development of China's power grid,zinc oxide surge arresters are evolving towards direct current(DC),extra high voltage,and miniaturized tank high-performance designs.Internally,valve plates are developing towards high gradi-ent,high nonlinearity,large current capacity,low residual voltage,low leakage,and integrated AC/DC capabilities.This article analyzes the impact of the manufacturing formula and process on the electrical performance of the valve plates and summarizes research methods for further improving the electrical characteristics of the zinc oxide valve plates.关键词
