Overhead insulation lead lightening protection wire breaking device

Abstract

The invention discloses an overhead insulation lead lightening protection wire breaking device. The device comprises a cross arm, an insulator and an insulation lead, wherein the insulator is arrangedon the cross arm, the insulation lead is arranged on the insulator, the insulation lead is provided with two puncture type connecting fittings, the puncture type connecting fittings are respectivelyarranged on the insulation lead at two sides of the insulator, the insulation lead is connected in parallel with a bare conductor, and two ends of the bare conductor are connected in parallel with theinsulation lead through connecting with conductor connection portions of the puncture type connecting fittings. The device is advantaged in that one lead is connected in parallel with two ends of theinsulation lead taking the insulator as the center through utilizing the two puncture type connecting fittings, reconstruction cost is quite low, enforcement is convenient, the lightening protectionwire breaking effect is obvious, popularization and enforcement are facilitated, the device is convenient to mount, a sealing structure is further employed, the water can be prevented from entering the insulation lead, corrosion is prevented, and service life is longer.

Description

technical field [0001] The invention relates to the technical field of anti-lightning disconnection protection for overhead insulated transmission lines of power system distribution networks, in particular to an anti-lightning disconnection device for overhead insulated wires. Background technique [0002] Distribution lines are mainly responsible for the distribution of electric energy and are an important part of the power system. Distribution lines are directly connected with power users, and their safety and reliability directly affect the power quality and reliability of power users. With the development of society and the increasing dependence of power users on power, the reliability and importance of distribution lines Sex is getting more and more attention. Distribution network lines are mainly divided into overhead lines, overhead insulated wire lines and cable lines. Overhead insulated wire lines have the advantages of safety, reliability, economy, and convenient ...

AI Technical Summary

Problems solved by technology

[0004] At present, the main lightning protection and disconnection measures for overhead insulated lines at home and abroad mainly include adding overhead lightning protection lines, installing zinc oxide arresters, improving line insulation levels, using clamp insulators, adding current-limiting arc suppression angles, and increasing line overvoltages. Protectors and other technical measures, but these lightning protection methods have disadvantages such as difficult construction, high cost of new construction or renovation, which limit their application on overhead insulated lines of distribution network
