Abstract

Disclosed in the invention is a portable power transmission line sag detection apparatus comprising a pedestal and a programmable controller arranged at the pedestal. A left walking mechanism and a right walking mechanism that have identical structures are arranged at the pedestal; a locking mechanism is arranged between the left walking mechanism and the right walking mechanism; and a foreign matter processing mechanism is arranged at the left side of the left walking mechanism. With the detection apparatus, a problem of retreating even falling during climbing can be solved. Moreover, the foreign matter processing efficiency is high and the effect is good; and the wire sag can be detected well.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, in particular to a portable power transmission line sag detection device. Background technique [0002] The transmission and distribution network is mainly composed of overhead transmission wires and ground wires. The overhead transmission wire is mainly composed of two parts: the conductive layer and the supporting layer. The material of the conductive layer includes aluminum and aluminum alloy, and the material of the supporting layer includes galvanized steel wire, aluminum clad steel wire and carbon fiber rod. Traditional overhead power transmission lines can only realize power transmission. The Chinese patent No. 02217735.3 "An Optical Fiber Composite Overhead Ground Wire" is composed of an optical fiber unit and an aluminum-clad steel wire or galvanized steel wire concentrically twisted. Transmission and power communications. Patent No. 200420094107.9 of the Chinese pat...
