Abstract
A shielding power transmission line pole tower lightning-protection ring comprises a first-layer head grading ring, a second-layer head grading ring, a shunting support, a bent main support, a mounting fixer and the like, and is characterized in that the main support of the lightning-protection ring is bent, and the upper end of the bent main support is fixedly connected with the shunting support while the lower end is fixedly connected with the mounting fixer. The head grading rings of the lightning-protection ring can be arranged into 1-5 layers, wherein the first-layer head grading ring is higher than or equal to the second-layer head grading ring in height, the second-layer head grading ring is higher than or equal to a third-layer head grading ring in height, and the rest can be deduced in the same manner. The shielding power transmission line pole tower lightning-protection ring can be conveniently mounted at the top of a power transmission line to shield a power transmission line pole tower and greatly weaken the lightning guide performance of the top of the power transmission line pole tower, thereby performing the function of lightning protection.
Description
Title of the present utility model is: the lightning-arrest ring of protected type electric power line pole tower.
Technical field
The utility model is used 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 the electric power line pole tower lightning protection, might cause the insulator string of electric power line pole tower to suffer the back flashover overvoltage injury.
Summary of the invention
The purpose of this utility model is to provide the protected type electric power line pole tower lightning-arrest ring, and the lightning-arrest ring of this shaft tower can overcome the existing existing above-mentioned defective of lightning rod.
Design of the present utility model is to realize like this, it comprises eight parts such as ground floor head grading ring, second layer head grading ring, shunting support, holder,head, holder,head connector, main support, main support connector, main support fixing holder, the main support that it is characterized in that it can be provided with bending in 0 °～180 ° scopes, holder,head connector and main support connector are fabricated structure.Its head grading ring can be set to 1～5 layer, wherein, ground floor head grading ring be higher than or etc. be higher than second layer head grading ring, second layer head grading ring be higher than or etc. be higher than the 3rd layer of head grading ring, by that analogy.
The utility model can be installed in the electric power line pole tower top easily, never with direction shielding shaft tower is installed.At thunderstorm weather, what it can weaken the electric power line pole tower top greatly draws the thunder performance, prevents the shaft tower that is struck by lightning.
Therefore, than existing lightning rod, the utlity model has following remarkable advantage:
1, can shield electric power line pole tower from different directions, what weaken the electric power line pole tower top greatly draws the thunder performance, thereby plays the effect of lightning protection, makes the electric power line pole tower lightning protection more safe and reliable.
2, design, manufacturing, construction and installation are easy.
3, low price, long service life.
