Description

TECHNICAL FIELD

[0001] The utility model relates to distribution line technical field, especially a simple 10kV straight pole overhead lightning conductor device structure. BACKGROUND

[0002] The lightning overvoltage on the distribution line is divided into two kinds of direct lightning overvoltage and lightning induction overvoltage. The direct lightning overvoltage is produced by lightning cloud discharge hitting overhead insulated line, and because the insulation level of the distribution line is low and the phase distance is small, the direct lightning may hit one phase or hit multiple phases at the same time, which easily causes phase-to-phase short circuit. The lightning induction overvoltage is produced on the line by electromagnetic induction through the object on the ground or the ground near the lightning hitting overhead insulated line, and the lightning induction overvoltage on the three-phase conductor has the same polarity and similar amplitude, which may cause single-phase flashover or develop into phase-to-phase short circuit.

[0003] In the past distribution network engineering design process, the lightning protection of 10kV overhead line mainly relies on the installation of line lightning arresters. After a long time of operation, the line lightning arresters are prone to internal faults, which reduces the lightning protection effect, and the faulty lightning arresters are not easy to identify and replace, which causes power supply hidden danger of the line. SUMMARY

[0004] Therefore, the utility model aims at providing a simple 10kV straight pole overhead lightning conductor device structure which can solve the lightning protection problem of straight pole, and the lightning stroke of the conductor can be converted into back flashover of the lightning conductor after lightning stroke, and the discharge of lightning current by the pole and the lightning conductor is shunted, which is beneficial to reduce the energy flowing through the line metal oxide lightning arrester.

[0005] The utility model adopts the following method to realize: a simple 10kV straight pole overhead lightning conductor device structure, including straight pole body, the straight pole body is equipped with the hoop, be provided with the fixed part for realizing lightning conductor fixed on the hoop, the fixed part includes U ring, U ring is connected with the hoop setting, the lower end of U ring is connected with the overhang wire clamp, the first aluminum tape is embedded on the overhang wire clamp, the first steel strand is embedded in the first aluminum tape or the fixed part includes the supporting plate, the supporting plate is arranged in the front of the hoop, the front of the supporting plate is hingedly provided with U-shaped limiting block on both ends, the upper vertical rod of U-shaped limiting block extends outwardly with the extension block, the extension block is fixed on the supporting plate through the bolt, the second aluminum tape is arranged in the U-shaped limiting block, and the second steel strand is arranged in the second aluminum tape.

[0006] The utility model discloses beneficial effect lies in: the utility model discloses has added the hoop and the fixing spare in the device, need not install a large number of line lightning arrester, only need erect and install a steel strand on overhead line top, set up lightning conductor can convert the flashover caused by the direct lightning of lightning conductor into the counterattack flashover after lightning, and the discharge of lightning current of electric pole and lightning conductor is shunted, and it is favorable for reducing the energy of flowing through line metal oxide lightning arrester, through full and modeling analysis and actual installation on the spot, not only can satisfy 10kV straight pole overhead lightning protection requirement, but also can be adjusted flexibly according to the installation position on the spot, improve construction efficiency, and improve power supply quality.
