Description

Technical Field

[0001] The utility model relates to the technical field of distribution lines, in particular to a structure of a simple 10kV tension pole overhead lightning protection wire device. Background Art

[0002] The lightning overvoltage on the distribution line is divided into two types: direct lightning strike overvoltage and lightning induction overvoltage. The direct lightning strike overvoltage is generated by the lightning discharge hitting the overhead insulated line. Due to the low insulation level and small phase distance of the distribution line, the direct lightning strike may hit one phase or multiple phases at the same time, easily causing phase-to-phase short circuit. The lightning induction overvoltage is generated by the lightning hitting the ground near the overhead insulated line or the electromagnetic induction on the line by the objects on the ground. The lightning induction overvoltages on the three-phase conductors have the same polarity and similar amplitudes, which may cause single-phase flashover or develop into phase-to-phase short circuit.

[0003] In the past, during the design process of the distribution network project, the lightning protection of the 10kV overhead line tension pole mainly relied on installing an integrated fixed-gap lightning arrester. After a long operation time, the internal failure of the line lightning arrester was likely to occur, resulting in a discounted lightning protection effect. Moreover, the faulty lightning arrester was not easy to identify and replace, making the line have a power supply hidden danger. Summary of the Invention

[0004] In view of this, the purpose of the utility model is to provide a structure of a simple 10kV tension pole overhead lightning protection wire device that can realize that by setting the lightning protection wire, the flashover caused by the direct lightning strike on the conductor can be converted into the counterattack flashover after the lightning strikes the lightning protection wire, and the electric pole and the lightning protection wire simultaneously shunt the discharge of the lightning current, which is beneficial to reducing the energy flowing through the line metal oxide lightning arrester.

[0005] The utility model is realized by the following method: A structure of a simple 10kV tension pole overhead lightning protection wire device includes a tension pole body. A hoop is sleeved on the upper end of the tension pole body. The left and right ends of the hoop are connected and fixed with UT wire clips through first bolts. A lightning protection wire is connected to the UT wire clips, and a parallel groove clamp is arranged on the lightning protection wire.

[0006] Further, the UT wire clip includes a U-shaped block. The U-shaped block is connected to the hoop through a first bolt. The ends of the two vertical rods of the U-shaped block are sleeved with connecting blocks through nuts. An arc-shaped clamping block is arranged at the end of the connecting block. A screw is spirally embedded in the arc-shaped clamping block. A first clamping block is arranged at the end of the screw. A first anti-slip layer is arranged on the end face of the first clamping block. Extension blocks extend outward from the front and rear end faces of the upper and lower arc-shaped clamping blocks. The extension blocks are connected through second bolts.

[0007] Further, the parallel groove clamp includes a first clamping plate and a second clamping plate. One end of the first clamping plate and the second clamping plate is hinged, and the other end of the first clamping plate and the second clamping plate is connected by a third bolt. Second clamping blocks are arranged on the inner sides of the first clamping plate and the second clamping plate, and a second anti-slip layer is arranged on the end face of the second clamping block.

[0008] The beneficial effects of the present utility model are as follows: The lightning protection wire, the UT clamp and the parallel groove clamp are added to the device, which can realize the installation of the lightning protection wire on the strain pole body, and can better solve the lightning protection problem of the strain pole. Setting the lightning protection wire can convert the flashover caused by direct lightning strike on the conductor into the counterattack flashover after lightning strike on the lightning protection wire. The pole and the lightning protection wire simultaneously shunt the discharge of the lightning current, which is beneficial to reducing the energy flowing through the line metal oxide lightning arrester. This device can not only meet the lightning protection requirements of the 10kV strain pole overhead line, but also be flexibly adjusted according to the on-site installation position, improve the construction efficiency, and improve the power supply quality.
