As preferably, interior electrode excircle offers several screws, and umbrella sheath, the corresponding screw of insulating cylinder offer through hole, on screw and interior electrode, screw spins, interior electrode is fixedly connected with umbrella sheath, insulating cylinder, and arcing ring and screw are fixed, and arcing ring is communicated with interior electrode, resistor disc.
As preferably, described screw comprises the end of thread and the end that spins, and spins and holds end face to start there is screwed hole, and arcing ring pin and screwed hole spin fixing.
As preferably, described arcing ring is made up of at least 2 balancing poles that are socketed on the hood type ring body on umbrella sheath surface, be connected with ring body excircle and the striking ring body being connected with balancing pole outer end, on ring body, offer the through hole corresponding with interior electrode screw, by screw, ring body is connected with interior electrode.
As preferably, arcing ring is socketed on insulating cylinder and offers earth pressure release groove place.Make the d/d gas of arcing ring (being also earth pressure release mark) wash open or be out of shape by this kind of setting; form significantly mark; while making operation maintenance personnel inspection circuit, can find very easily that the anti-thunder insulator breaking down changes; avoid the generation of distribution network systems decompression and relaying protection action trip condition; thereby avoid because of broken string, insulator arc-over or puncture causing the loss of large-area power-cuts and electricity sales amount or causing great personal injury accident; ensure normal power supply; increase economic benefit, improved operation maintenance and power supply reliability.
As preferably, insulating cylinder is epoxy cylinder.
As preferably, resistor disc is zinc oxide resistance sheet.
As preferably, below interior electrode, be provided with adjustment cushion block.
The beneficial effects of the utility model: the utility model forms dual lightning protection inter space by setting up arcing ring, greatly improve lightning protection properties, and effectively prevent that insulator internal gas from sharply expanding, wash gold utensil open or destroy epoxy cylinder, cause anti-thunder insulator to damage, and gas impacts arcing ring and causes bending to play obvious mark, can find very easily that the anti-thunder insulator breaking down changes while making operation maintenance personnel inspection circuit.
