Abstract

A 10kV distribution line tower lightning protection device is composed of a lightning rod, a support rod, a clamp, bolts, etc. The lightning rod (1) is formed by bending a vertical part and a diagonal brace. The lower end of the diagonal brace of the lightning rod (1) is welded to the clamp (4) and the grounding connection plate (6). The lower end of the vertical part of the lightning rod (1) is welded to the support rod (2). The other end of the support rod (2) is welded to the clamp (3). The clamp (3) and clamp (4) are made of flat iron bent into two semi-circles with ears and drilled with holes and connected by bolts (5). During installation, the clamp (3) and clamp (4) are fixed to the tower of the distribution line with bolts (5). The grounding connection plate (6) is connected to the grounding wire. This device can greatly reduce the direct lightning strike on the conductor and avoid accidents such as wire breakage, grounding, circuit breaker tripping, and equipment damage.

Description

10kV Distribution Line Tower Lightning Protection Device

technical field

The utility model relates to a power line lightning protection device, in particular to a 10kV power distribution line tower lightning rod.

Background technique

The 10kV power distribution line is equipped with lightning protection devices at the station area and the head end. However, since the 10kV power distribution lines are relatively long, lightning strikes cause disconnection, grounding, tripping, and equipment damage accidents often occur. Therefore, further solutions are needed.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art and design a kind of 10kV power distribution line tower lightning protection device.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a 10kV power distribution line tower lightning protection device, which is composed of a lightning rod, a support rod, a hoop, and a bolt, and is characterized in that: the lower end of the vertical part of the lightning rod (1) is connected to the support rod ( 2) Welding, the other end of the support rod (2) is welded with the upper hoop (3), the lower end of the diagonal brace of the lightning rod (1) is welded with the lower hoop (4) and the ground connection plate (6), and the upper hoop ( 3), the lower hoop (4) is respectively bent by two flat irons and drilled with holes to connect with bolts (5).

As a preference, the 10kV distribution line tower lightning protection device according to claim 1 is characterized in that: the support rod is a V-shaped support rod (7), and the elbow end of the V-shaped support rod (7) is vertical to the lightning rod (1). The lower end of the part is surrounded and welded, and the other two ends of the V-shaped support rod (7) are welded with the upper hoop (3).

The beneficial effects of the utility model compared with the prior art are:

It greatly reduces the disconnection, grounding, tripping and equipment damage accidents caused by lightning strikes. The production process is simple, the cost is low, and the installation is convenient.
