摘要（英）：

The invention discloses an apparatus for detecting a high-voltage cable by using reflection high-energy electron diffraction and belongs to the field of damage-free detection of high voltage cables. The invention provides an apparatus which can detect a high voltage cable which is at an online operation state in a damage-free manner by using reflection high-energy electron diffraction. According to the invention, the apparatus includes an interdigital transducer, a solar panel, a storage battery and a control unit. The apparatus is structured in that: the control unit includes a PIC18F4520/TQFP chip U1, a CA258P chip U3, and a LM239U4, a 2 pin of the U3 are respectively connected to one end of a resistor R11 and one end of a resistor R12, the other end of the R12 is connected to an output end of the solar panel, the other end of the R11 is in separate connection to 1 pin of the U3 and one end of a resistor R30, and the other end of the R30 is connected to a 27 pin of the U1.
