Research on the Application of Phased Array Detection Technology in Composite Insulator Interface Debonding Detection

Abstract

The main reasons for the failure of composite insulator are the fracture of core rod and the breakdown of interface. However, due to the particularity of composite insulator, the traditional insulator detection method is not fully applicable to it. In this paper, phased array detection technology is used to detect the interface debonding defects of composite insulator sheath and core rod, and clear interface debonding signals are obtained. The research results can provide research basis for the application of phased array detection technology in the field of composite insulator defect detection.
