Background

The overhead transmission line has great significance for normal and safe power supply by keeping the conductor intact. With the continuous development of power grids, the transmission capacity and the voltage grade of a power transmission line are continuously improved, and a multi-split conductor is generated in order to inhibit corona discharge and reduce line reactance. The space between the split conductors is small, and the corners of the strain tower are large or small, so that the strain drainage wire is easily contacted with the hardware, and the strain drainage wire and the hardware are easily damaged under the action of external force such as wind. In order to ensure reasonable clearance between the drainage wire and the connecting hardware fitting, avoid fatigue damage of the strain clamp and avoid damage caused by whipping and colliding of the wire to the hardware fitting, the distance-adjusting spacer is gradually and widely applied.

The distance-adjusting spacing rod mainly comprises a wire fixing clamp, an extension pull rod fixing clamp and a fastening nut. The wire fixing clamp consists of a wire fixing clamp body a, a wire fixing clamp cover plate b and an eyelet bolt c, and the extension pull rod fixing clamp consists of an extension pull rod fixing clamp body d, an extension pull rod fixing clamp cover plate e and an eyelet bolt f. A conventional spacer structure is shown in fig. 1.

The connecting end of the lead fixing clamp body a is designed into a threaded pipe form, and the structure is shown in figure 2; the connecting end of the extension pull rod wire clamp body d is designed into a threaded rod form, and the structure is shown in figure 3. The two are in threaded connection, and the distance is adjusted by rotating the threads. The wire clamp body is connected with one end of the wire clamp cover plate through a pin shaft, the cover plate can freely rotate along with the pin shaft, the matching surface of the other end is designed into a plane form, and the wire clamp body and the wire clamp cover plate are connected through the swing bolts c and f, the swing bolts also rotate along with the pin shaft and freely swing in the swing bolt mounting grooves.

The distance-adjusting spacing rod in the structural form is relatively troublesome to install, a plurality of constructors are required to be matched, the relative positions of the drainage wire and the wire fixing wire clamp body a need to be fixed firstly, then the drainage wire is fixed by installing one end of the drainage wire, the wire clamp body d is fixed by installing the extension pull rod by opening the chuck at the other end of the drainage wire, and meanwhile the two chucks are adjusted by threads to be fixed by tightening the fastening nut after the distance between the two chucks and a reasonable distance is obtained.

Once the installation is accomplished, if need readjust the drainage wire and the relative position of extension pull rod fixed clamp body d, need pull down the roll adjustment conductor spacer again, then look for suitable position and reinstall, greatly increased the work load of construction installation.
