Description

Technical Field

[0001] The utility model relates to the technical field of power distribution lines, in particular to a simple 10kV straight gate-shaped pole overhead lightning conductor device fixing structure. Background Art

[0002] Lightning overvoltages on distribution lines are categorized as direct lightning overvoltage and lightning-induced overvoltage. Direct lightning overvoltage is generated by a thundercloud discharge striking an insulated overhead line. Due to the low insulation and small phase-to-phase distances of distribution lines, direct lightning strikes can strike a single phase or multiple phases simultaneously, easily causing a phase-to-phase short circuit. Lightning-induced overvoltage is generated by electromagnetic induction from lightning striking the ground or objects on the ground near an insulated overhead line. These lightning-induced overvoltages on the three-phase conductors have the same polarity and similar amplitude, potentially causing single-phase flashover or developing into a phase-to-phase short circuit.

[0003] In the past distribution network engineering design process, 10kV overhead line lightning protection mainly relied on the installation of line lightning arresters. After a long period of operation, the line lightning arresters were prone to internal failures, which reduced the lightning protection effect. In addition, the faulty lightning arresters were not easy to identify and replace, which caused power supply risks to the lines. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a simple 10kV straight gate-shaped pole overhead lightning conductor device fixing structure that can solve the lightning protection problem of long-span straight gate-shaped poles.

[0005] The utility model adopts the following method to achieve: a simple 10kV straight gate-shaped pole overhead lightning protection line device fixing structure, including a pole body, a plurality of connecting clamps are equidistantly sleeved on the upper end of the pole body, the left end of the connecting clamp is connected to the first clamping rod, the right end of the connecting clamp is connected to the second clamping rod, and the first clamping rod and the second clamping rod are connected to steel strands.

[0006] Furthermore, a reinforcing rod is connected between the first clamping rod and the second clamping rod via bolts.

[0007] Furthermore, a first arc-shaped groove is formed on the upper end of the inner side surface of the first clamping rod, and a second arc-shaped groove matching the first arc-shaped groove is formed on the upper end of the inner side surface of the second clamping rod.

[0008] The beneficial effects of the present invention are as follows: the present invention adds a steel strand, a first clamping rod and a second clamping rod to the device, and there is no need to install a large number of line lightning arresters. It is only necessary to install a steel strand (lightning conductor) above the overhead line. The lightning conductor can convert the flashover caused by direct lightning striking the conductor into a counter-flashover after the lightning strikes the lightning conductor. The first clamping rod and the second clamping rod and the lightning conductor simultaneously shunt the discharge of the lightning current, which is beneficial to reducing the energy flowing through the metal oxide lightning arrester of the line. The present device can not only meet the lightning protection requirements of 10kV straight gate-shaped pole overhead lines, but also can be flexibly adjusted according to the on-site installation position, thereby improving construction efficiency and improving power supply quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a structural diagram of the first state of the utility model.

[0010] Figure 2 This is a structural diagram of the second state of the utility model. DETAILED DESCRIPTION

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] See also Figure 1 and Figure 2 As shown, the utility model provides an embodiment: a simple 10kV straight gate-shaped pole overhead lightning conductor device fixing structure, comprising a pole body 1, a plurality of connecting clamps 2 equidistantly sleeved on the upper end of the pole body 1, a first clamping rod 3 connected to the left end of the connecting clamp 2, a second clamping rod 4 connected to the right end of the connecting clamp 2, and steel strands 5 connected to the first clamping rod 3 and the second clamping rod 4. This eliminates the need to install a large number of line lightning arresters, and only requires a single steel strand (lightning conductor) to be installed above the overhead line. The lightning conductor can convert the flashover caused by direct lightning strikes on the conductor into a counter-flashover after the lightning strikes the lightning conductor. The pole and the lightning conductor simultaneously shunt the discharge of lightning current, which helps reduce the energy flowing through the metal oxide lightning arrester of the line.
