Abstract
The utility model relates to high tension insulator electrical equipment, specifically relates to a kind of built on stilts single back line lightning arrester.A kind of built on stilts single back line lightning arrester, comprise pillar body, it is characterized in that: in the middle part of described pillar body, cross bar is installed, bottom is provided with the A-frame for support rail, described pillar bodies top and cross bar two ends are separately installed with lightning arrester, described lightning arrester connects earth lead, and described earth lead is arranged on pillar body.The one of this spline structure makes somebody a mere figurehead single back line lightning arrester, and to have lightning protection effect good, the advantage that anti-lightning zone is wide.
Description
Technical field
The utility model relates to high tension insulator electrical equipment, specifically relates to a kind of built on stilts single back line lightning arrester.
Background technology
Lightning arrester mainly for the protection of ultra-high-tension power transmission line, not by effect that thunder and lightning destroys.
Existing lightning arrester is mostly single installation and connects high pressure and ground connection, and the lightning arrester of this spline structure exists lightning protection effect difference, and anti-lightning zone is little, cannot meet the shortcoming of existing demand.
Summary of the invention
The purpose of this utility model is exactly that it is good that the one provided has lightning protection effect, the built on stilts single back line lightning arrester that anti-lightning zone is wide for above-mentioned existing shortcoming.
The technical solution of the utility model is achieved in that a kind of built on stilts single back line lightning arrester, comprise pillar body, it is characterized in that: in the middle part of described pillar body, cross bar is installed, bottom is provided with the A-frame for support rail, described pillar bodies top and cross bar two ends are separately installed with lightning arrester, described lightning arrester connects earth lead, and described earth lead is arranged on pillar body.
Described lightning arrester is provided with main lightning-arrest insulator and pair and takes shelter from the thunder insulator, and described master insulator bottom of taking shelter from the thunder is provided with ground connections, and centre is provided with high voltage connections, is provided with secondary lightning-arrest insulator between described ground connections and high voltage connections end.
Described ground connections is Z-shaped structure.
The beneficial effects of the utility model are: the one of this spline structure makes somebody a mere figurehead single back line lightning arrester, and to have lightning protection effect good, the advantage that anti-lightning zone is wide.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, pillar body 2, cross bar 3, A-frame 4, lightning arrester 5, earth lead 6, main lightning-arrest insulator 7, secondary lightning-arrest insulator 8, ground connections 9, high voltage connections.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1: a kind of built on stilts single back line lightning arrester, comprise pillar body 1, it is characterized in that: in the middle part of described pillar body 1, cross bar 2 is installed, bottom is provided with the A-frame 3 for support rail 2, described pillar body 1 top and cross bar 2 two ends are separately installed with lightning arrester 4, described lightning arrester 4 connects earth lead 5, and described earth lead 5 is arranged on pillar body 1.
Described lightning arrester 4 is provided with main lightning-arrest insulator 6 and pair and takes shelter from the thunder insulator 7, described master insulator 6 bottom of taking shelter from the thunder is provided with ground connections 8, centre is provided with high voltage connections 9, is provided with secondary lightning-arrest insulator 7 between described ground connections 8 and high voltage connections 9 end.
Described ground connections 8 is in Z-shaped structure.
The one of this spline structure makes somebody a mere figurehead single back line lightning arrester, and to have lightning protection effect good, the advantage that anti-lightning zone is wide.
