摘要
Abstract
The phased array technology can be used to detect the seal defects in the intermediate joint of high-voltage cable,but the successful application of this technology is based on the clear structure of the joint and the clear position of the seal.Because of the complex structure of the intermediate joint,it is difficult to determine the exact position of the seal after installation,resulting in difficult identification of defects and low detection rate.On this basis,an ultrasonic based multi-layer structure location detection method for high-voltage cable intermediate joint is proposed.The models of different structural regions are established according to intermediate joints.Comsol simulation software is used to analyze three different structural regions of the liner section,seal edge section and seal section by the ultrasonic scanning.Different structural areas of the intermediate joint are tested.After comparative analysis,it can be seen that obvious insulation sealant echoes appear at 3.5 mm,heat shrink pipe(waterproof tape)echoes appear at 34.5 mm,22 mm and 24 mm,and lead seal(liner)echoes appear at 36.5 mm,24 mm and 26 mm.The experimental results show that the proposed method can reflect the structure information of each layer of the intermediate joint quickly and intuitively,and provide a certain reference for the multi-layer structure location detection of the high-voltage cable intermediate joint.关键词
