<p><P>PROBLEM TO BE SOLVED: To provide a self-propelled electric wire inspection apparatus of a relatively inexpensive constitution capable of traveling over even power transmission lines of multiple conductors and jumper wires and inspecting the interior of electric wires. <P>SOLUTION: Traveling rollers 5a and 5b are provided for above and below electric wires 1. Bending loads are added from above and below in such a way as to be engaged with the electric wires 1. Sound when the electric wires 1 are bent by the bending loads is judged by an acoustic sensor 6 to detect anomalies of the electric wires 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
