Intelligent anti-thunder distribution line overhead line structure

Abstract

The invention relates to the technical field of distribution lines, and specifically relates to an intelligent anti-thunder distribution line overhead line structure. The intelligent anti-thunder distribution line overhead line structure comprises a tower, an overhead ground wire, a ground wire support, an insulated tower top and a tower ground wire, wherein the overhead ground wire is an opticalfiber cable, a metal stranded wire is arranged on the outer layer of the optical fiber cable, and an optical fiber is arranged on the inner layer of the optical fiber cable. The optical fiber cable isspanned on the distribution line overhead line structure, the metal stranded wire on the outer layer of the optical fiber cable has the effects of shielding lightning strokes and coupling and reducing lightning current, the optical fiber has a communication function, and simultaneously, intelligent sensing for distribution lines is realized by using a photoelectric effect of the optical fiber andmonitoring wire load current, fault current, tower vibration and the like in a non-contact mode. By setting the insulated tower top and the overhead ground wire, the insulation level of the overheadline structure is greatly promoted through the insulated tower top, and the overhead ground wire has the effect of shielding lightning strokes, so that the lightning withstand level of the distribution line overhead line structure is greatly promoted. By using the intelligent anti-thunder distribution line overhead line structure, the damage on the distribution lines caused by lightning strokes can be reduced, moreover, the power supply reliability of the distribution lines is improved, and high-quality electric power service is provided.

Description

technical field [0001] The invention relates to the technical field of power distribution lines, in particular to an intelligent lightning protection power distribution line tower. Background technique [0002] Among the common distribution lines, the insulation level of 10kV overhead distribution lines is low, and lightning strikes the conductors easily causing distribution line faults. The current 10kV distribution overhead lines basically do not add lightning protection wires. However, with the improvement of society's requirements for the reliability of distribution network power supply, the research and application of lightning protection lines for 10kV overhead lines are also in-depth. In recent years, measures to erect lightning protection lines for 10kV overhead lines at home and abroad have achieved certain results. In common distribution lines, the installation of overhead lightning protection lines on distribution network lines can reduce the lightning-induced ove...

AI Technical Summary

Problems solved by technology

[0003] At present, the overhead ground wires erected on the towers of distribution lines are all metal stranded wires, which only have the function of lightning protection. It can be seen that the ground wires erected on distribution lines are only for lightning protection, and the economical and technical characteristics are relatively poor.
