摘要
Abstract
Because of its light weight,excellent pollution flashover performance,high mechanical strength and easy maintenance,composite insulators are widely used in our country about ten million. But for its particularity, the traditional insulator detection methods cannot be completely used in the composite insulator's detection,so it needs a new type composite insulator testing technology to promote the development of composite insulators. In this paper, we test the through ability of X-ray for composite insulator,and we get some parameters for the X-ray detection technology for composite insulator. Then we use the nondestructive testing technology of X-ray to detect lots of simulation defects in four areas of composite insulators (the umbrella skirt and sheath area,the mandrel area,the connection interface between the sheath and the mandrel,the metal parts area),to detect some used composite insulators,with those parameters. From the many X-ray imaging drawing we get,it can be clearly see that the internal structure of composite insulators,that the defects type and their position,and it can be measured the sheath thickness and the mandrel diameter. The result can be used as a practical reference for the X-ray detection technology for composite insulators' defect detection and type detection.关键词
