摘　　要：电气设备失效会严重威胁电网安全。为了确保电网安全可靠运行,也为了给电气设备的状态检测评价和预测评估及故障诊断提供科学依据,对电气设备进行系统深入地失效分折显得尤为重要。分析了电气设备失效的成因、特征及发展过程。The electrical equipment failure can seriously damage the safety of the power grid. In order to ensure the safe and reliable operation of the power grid,the electrical equipment is examined and evaluated,and it provides the scientific basis to the fault diagnosis. It has special significance to conduct deeply and systematically study to the electrical equipment failure. The cause of formation,the characteristics and the failure developing process of electrical equipment failure are presented.
