A kind of special external series gap lightning arrester of electric railway, including insulator and arrester, it is characterised in that：The arrester includes two lightning arrester bodies and two bar electrodes, described two lightning arrester bodies and two bar electrodes are connected by the form connected, the insulator is respectively arranged at the two ends with a lightning arrester body, the lightning arrester body is provided with protective coat, the other end of the lightning arrester body is provided with a bar electrode, the bar electrode includes discharging rod and discharge metal head, and the discharging rod and discharge metal head are Integral connection structure, and series gap is formed between described two bar electrodes.What the utility model reached has the beneficial effect that：Simple structure, easy for installation flexible, simple gap dielectric change or simple power frequency high voltage pulse can not all cause the misoperation of arrester to be tripped, and substantially increase networking normality security.
Description
Technical field
The present invention relates to electric equipment field, a kind of lightning-arrest dress in the special external series gap of electric railway is related specifically to
Put.
Background technology
High-speed railway corridor is linearly distributed, distance, and region span is big, and lightening activity is more frequent along the line, high at present
Fast railway contact line mainly uses lightning conducter as the major measure of thunder-lightning, but the tripping rate with lightning strike of this lightning protection measures is very
Height, in order to make up the deficiency of lightning conducter lightning protection measures, zinc oxide arrester with series gaps is introduced in applied to high-speed railway touching net,
But current zinc oxide arrester with series gaps structure is single, simple gap dielectric change or simple power frequency high voltage pulse all can
Cause the misoperation of arrester to be tripped, increased the workload of arrester later maintenance.
Utility model content
In order to solve the above problems, it is special outer that the utility model provides a kind of electric railway for reducing misoperation tripping operation
Series gap lightning arrester.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of electric railway is special outer
Series gap lightning arrester, including insulator and arrester, it is characterised in that：The arrester include two lightning arrester bodies and
Two bar electrodes, described two lightning arrester bodies and two bar electrodes are connected by the form connected, and the insulator two ends are each
A lightning arrester body is provided with, the lightning arrester body is provided with protective coat, and the other end of the lightning arrester body is provided with one
Bar electrode, the bar electrode includes discharging rod and discharge metal head, and the discharging rod and discharge metal head are Integral connection structure,
Series gap is formed between described two bar electrodes.
Further technical scheme is：The insulator is AF bar shape suspension insulators or the horizontal bracket insulation of T lines
Son.
Further technical scheme is：The lightning arrester body is fixed on insulator two in the form of anchor ear is installed
End.
Further technical scheme is：The material of the protective coat is silicon rubber.
Further technical scheme is：The discharging rod of the bar electrode is wrapped up using silica gel.
Further technical scheme is：The discharge metal head of the bar electrode is hemispherical.
It is using the beneficial effect produced by above-mentioned technical proposal：
Simple structure, it is easy for installation flexible, because using two duplexes of lightning arrester body, simple gap dielectric becomes
Change or simple power frequency high voltage pulse can not all cause the misoperation of arrester to be tripped, substantially increase networking normality security.

Set 4, the other end of the lightning arrester body 2 is provided with a bar electrode 3, and the bar electrode 3 includes discharging rod 5 and discharge metal head
6, the discharging rod 5 and discharge metal first 6 are Integral connection structure, and series gap is formed between described two bar electrodes 3.
Further preferred：The insulator 1 is AF bar shape suspension insulators or the horizontal bracket insulator of T lines.
Further preferred：The lightning arrester body 2 is fixed on the two ends of insulator 1 in the form of anchor ear 7 is installed.
Further preferred：The material of the protective coat 4 is silicon rubber, and silicon rubber has good weatherability, effectively
Ground lightning arrester body is not corroded by wind and rain.
Further preferred：The discharging rod 5 of the bar electrode 3 is wrapped up using silica gel, is protected discharging rod not contaminated and is damaged
It is bad, improve the insulating properties of discharging rod.
Further preferred：The discharge metal first 6 is hemispherical, is prevented effectively from and the situation of point discharge occurs, so that
Protection device is not damaged by.
