Abstract
The two thunders of 10-35kV are escaped and are encircled shielding power transmission line pole tower composite lightning-protection device, it comprises the thunder ring of escaping, shunting support, the thunder ring splicing ear of escaping, left side folding type main support, left side splicing ear, left side fixing holder, grounding connection terminal, right lateral bend folding main support, right side splicing ear, right side fixing holder, the connecting screw of left side fixing holder and right side fixing holder, the left side splicing ear and the right side splicing ear that it is characterized in that it are respectively connected with the thunder ring splicing ear screw of escaping respectively, left side fixing holder is connected with right side fixing holder screw.And, its thunder escape ring higher than or wait higher than shunt support.The utility model can be arranged on electric power line pole tower top easily, and escaping to encircle with two thunders shields shaft tower on a large scale.At thunderstorm weather, what it can weaken electric power line pole tower top greatly draws thunder performance, thereby plays the effect of lightning protection.
Description
Technical field
The utility model is for the electric power line pole tower shocking preventing technology field of various electric pressures.
Background technology
The major defect of existing lightning rod is to draw Lei Jieshan, if be applied to electric power line pole tower lightning protection, the insulator string that likely causes electric power line pole tower is suffered to back flashover overvoltage injury.
Summary of the invention
The purpose of this utility model is will provide the two thunders of 10-35kV to escape to encircle shielding power transmission line pole tower composite lightning-protection device, and this composite lightning-protection device can overcome the existing above-mentioned defect of existing lightning rod.
Design of the present utility model is to realize like this, it comprises thunder the escape connecting screw of ring splicing ear, left side folding type main support, left side splicing ear, left side fixing holder, grounding connection terminal, right lateral bend folding main support, right side splicing ear, right side fixing holder, left side fixing holder and right side fixing holder of ring, shunting support, thunder of escaping, the left side splicing ear and the right side splicing ear that it is characterized in that it are respectively connected with the thunder ring splicing ear screw of escaping respectively, and left side fixing holder is connected with right side fixing holder screw.And, its thunder escape ring higher than or wait higher than shunt support.
The utility model can be arranged on electric power line pole tower top easily, and escaping to encircle with two thunders shields shaft tower on a large scale.At thunderstorm weather, what it can weaken electric power line pole tower top greatly draws thunder performance, thereby plays the effect of lightning protection.
Therefore,, than existing lightning rod, the utlity model has following remarkable advantage:
1, shield electric power line pole tower on a large scale with two thunders ring of escaping, what greatly weaken head of mast draws thunder performance, thereby plays the effect of lightning protection, makes electric power line pole tower lightning protection more safe and reliable.
2, design, manufacture, construction and installation are easy.
3, low price, long service life.
