摘　　要：针对电力绝缘子出现断裂、发热以及强度、阻值降低等故障,利用瓷壁耐压及陡波等试验方法,在不同试验条件下对各种用途的绝缘子进行出厂检测,保证了绝缘子的出厂质量,利用离线检测和在线检测方法,实现了运行中绝缘子故障检测的要求。离线检测方法以红外检测和紫外检测方法为发展方向,在线检测方法以泄露电流和脉冲电流法为主流检测方法。出厂前和运行中的离线、在线的检测方法对故障绝缘子有良好的检测效果,为研究绝缘子检测奠定了基础。Insulator on power system may appear break,heat,resistance and strength reduction before they go out and in service.Test methods of porcelain wall pressure and steep wave for various insulator use of the factory inspection under different experiment conditions.The testing is an important way to guarantee the insulator quality.Detection methods of offline and online meet the requirements of the detecting defects.In the offline testing,large area detection of infrared and ultraviolet are the development direction.The main online detection methods are the leakage current and pulse current methods.Methods which before they go out and in service have a good effect on the faulty insulator detection,and also lay a deep foundation for the new method and new technology in the future study of insulator detection.
