摘　　要：Shaanxi Electric Power（monthly issue）is a science and technology journal which is administrated by State Grid Corporation of China,sponsored by Shaanxi Electric Power Corporation.The journal mainly reflects the new achievement,new technology,new trend in the fields ofdomestic＆international energy,electric technology.The scopeofShaanxi Electric Power covers new energy and distributed power generation,In order to detect internal detect of composite insulators,this paper proposes a detection system based on microwave reflection nlethod for composite insulator detection,which transmits the microwave into the composite insulators. By ulilizing the property that microwave reflects and refracts in different media, the reflected wave signal is detected to determine whether the detects oeeur in internal insulator. The paper verifies the feasibility of the microwave reflection method by theoretical analysis, establishes an experimental platform to perform non-destructive testing experiments, summarizes the data distribution through experiments on samples without internal defects,and proposes preliminary criterion. Finally, the practical effect of the method is verified through experiments on samples with internal defeets. Experiments show that the microwave reflection method has an obvious effect on the detection of the internal detects of the composite insulators.
