Abstract
In order to prevent the occurrence of power grid security incidents, it is very necessary to carry out non-destructive testing of crimp-type power fittings involved in ultra-high-voltage transmission lines. In this paper, for the first time, we have carried out a non-destructive flaw detection application study on power fittings using portable X-ray backscatter imaging technology. It was found that the outline of the flaw detection image corresponding to the aluminum power fittings was clearly visible and the resolution was high. With the continuous maturity of the transmission line inspection robot technology, the portable X-ray backscattering equipment can be carried out autonomously with the help of the robot arm, which is expected to promote the rapid and diversified development of the field of non-destructive testing of electric power fittings.
