Zusammenfassung:To provide an AE measuring device for an electric wire that can easily make an AE measurement to determine a disconnection of an electric wire.SOLUTION: The shafts of a main pulley 20, a first sub pulley 30, and a second sub pulley 40 are located in a zigzag alignment in the substrate 10 of an AE measuring device 1. The main pulley 20, the first sub pulley 30, and the second sub pulley 40 are provided in the shafts. The main pulley 20, the first sub pulley 30, and the second sub pulley 40 hold an electric wire 300 while the device is moving along the electric wire 300, and a measurement is made on the AE wave of the electric wire 300. It thus becomes possible to easily and stably measure an accurate AE wave, with the radius of curvature, the angle, and the strength of the electric wire 300 being kept at a certain level.SELECTED DRAWING: Figure 1 【課題】電線の断線判定のためのAE測定を容易に行うことができる電線のAE測定装置を提供する。【解決手段】AE測定装置1の基板10に、メインプーリー20と、第1サブプーリー30と、第2サブプーリー40の各軸を千鳥状に配置し、各軸にメインプーリー20と、第1サブプーリー30と、第2サブプーリー40と、を設け、メインプーリー20と、第1サブプーリー30および第2サブプーリー40と、によって電線300を挟持しながら電線300に沿って移動して、電線300のAE波の測定を行うようにした。これにより、電線300の曲率半径、角度、強さを一定に保ちながら、AE波の測定を行うことができ、安定して正確なAE波を容易に測定することができる。【選択図】図1
