<p>PURPOSE: An apparatus for overcoming obstacles in a power transmission line is provided to pass a spacer damper and a suspension insulator as moving on the transmission line by being placed on the power transmission line of a live cable or a non-live cable. CONSTITUTION: An apparatus for overcoming obstacles in a power transmission line includes a plurality of travelling parts(100), an up/down moving unit, a sensing part, a control part and body frames(22a,22b,22c,23a,23b,23c,24a,24b,24c). The plurality of travelling parts include a pair of driving rollers which are placed on the transmission line and travel along the transmission line. The up/down moving unit combines or separates the driving roller with or from the transmission line by widening or narrowing a space between the driving rollers. The sensing part senses obstacles by being installed in the transmission line. The control part controls the driving of the travelling part and the up/down moving unit according to the sensing of the sensing part. The travelling part is installed in the body frames.</p> |
