Abstract
The utility model belongs to the technical field of electrical equipment structure and relates to a lightning protection device which comprises a lightning protection body. One end of an insulation terminal is fixed on the lightning protection body while the other end of the same is fixed through a fixing component, and an electroconductive electric rod, an electroconductive stator, a rain sheltering cover and a current drainage column are arranged on the lightning protection body. The electroconductive electric rod and the electroconductive stator are arranged at the top of the lightning protection body, so that when under a lightning attack, the electroconductive electric rod discharges towards the electroconductive stator, and the lightning protection device starts working and leads voltage into the ground; the current drainage column below the lightning protection body can increase throughput of lightning current, increase lightning leading speed and timely lead the lightning voltage into the ground; in severe environments like a thunderstorm and wind blowing, the rain sheltering cover can effectively block a lightning current passage between a lightning rod and the insulation layer and can cooperate with the insulation layer to play a certain role in protecting the lightning protection body, so that service life of the lightning protection device is prolonged.

Utility model content
The purpose of this utility model be to provide a kind of lightning-arrest intensity high, can be at the lightning arrester of long-term work under adverse circumstances.
A kind of lightning arrester of the present utility model, special character is to comprise lightning-arrest body 1, and insulated terminal 2 one end are fixed on lightning-arrest body 1, and one end is fixing by fixation kit 3;
Described lightning-arrest body 1 top is provided with bearing 4, bearing 4 tops are fixed with lightning rod 5, bearing 4 belows are fixed with conduction torch 6, conduction torch 6 is fixedly connected with conduction stator 7 by insulating supporting, lightning-arrest body 1 top is fixed in conduction stator 7 bottoms, lightning-arrest body 1 bottom is connected with earial drainage post 8, and earial drainage post 8 is fixedly connected with flange 10 by joint pin 9;
Described lightning-arrest body 1, bearing 4, insulated terminal 2 outsides are equipped with insulating barrier 11, and insulating barrier 11 intervals form the first valve block 12, are interval with the second valve block 13 on insulated terminal 2;
Described lightning rod 5 is provided with taking shelter from rain of umbrella with bearing 4 junctions and covers 14, and the cover 14 of taking shelter from rain is blocked the lightning current passage of lightning rod 5 and insulating barrier 11 completely.
One of the present utility model is improved and is, described the first valve block 12 is 4-6, and the second valve block 13 is 2-4.
The utility model another kind improves and is, the coating that described insulating barrier 11 makes for silicon rubber composite material.
