摘要
Abstract
The heterogeneity of oxidizing resistors is proposed leading to the deterioration of the resistors.The deteriorated resistor increases the leakage current and the power loss of the lightning arrester,resul-ting in the breakdown of the lightning arrester and affecting the secure and reliable operation of the power system.Based on on-site research,the zinc oxide resistor of lightning arrester was taken as the object of study,the aging characteristics of the zinc oxide resistor were analyzed through a combination of experi-ment and simulation.An accelerated aging test on zinc oxide resistor was conducted,and the accelerated aging characteristic curves of the resistor were obtained.The aging characteristic curve gradually decrea-ses with time and stabilized finally,indicating the long-term stability of the tested resistor.In addition,multi-physical field coupling simulation was conducted to intuitively analyze the cloud maps of surface temperature and electric field in the present experiment condition,as well as the streamline map of air-flow changes near the resistor.The simulation is a significant supplement to the existing aging test meth-ods,and the research results is valuable for the aging characteristics of zinc oxide resistor.关键词
