Due to the Zinc-Oxide Arrester existing defects of single gap, the arrester in series multiple gap is researched and developed as countries in the world Emphasis.
For example, Authorization Notice No. is CN105529617B Chinese invention patent, a kind of electric discharge main body, absolutely of including is disclosed The leakage conductor of edge and auxiliary electrode, wherein electric discharge main body includes metal electrode and substrate.The electric discharge main body is wrapped in On the insulator, the insulator upper and lower ends portion be provided with auxiliary electrode, the auxiliary electrode be used for connect high-tension line and Ground connection;The auxiliary electrode for being used to connect high-tension line and one end of the electric discharge main body constitute the second discharging gap or direct Connection;The auxiliary electrode for being used to be grounded is directly connected to the electric discharge main body other end, or another with the electric discharge main body End forms the 3rd discharging gap.
In another example, the Chinese utility model patent of Application No. 201420685764.4 discloses a kind of new gap and kept away Thunder device, including be elongated insulator and unit of an arrester, it is characterised in that its top of striking arm, which is provided with, is fixed on arrester Fixed cover on element, below provided with the sliding sleeve that can slide up and down, fixed cover and sliding sleeve connect with first connecting rod and second respectively One end of bar is rotated by swivel pin and connected, and the other end of first connecting rod and second connecting rod is rotatably connected on one by tumbler Rise, control device of the tumbler provided with the horizontal range between control first connecting rod and second connecting rod.It can be drawn by regulation The vertical distance of arc arm, so that the spacing between striking arm and grounding electrode is adjusted, to realize to different voltages, the guarantor of Multiple Type Protect the protection of cable.
The defect that above-mentioned prior art is present is:It is complicated, install inconvenient, it is impossible to which avoiding flashover, (flashover is existing As:During gas or breakdown liquid dielectric around solid insulator, along solid insulator surface discharge phenomena), resistant energy Power is not strong, using metal oxide resistance, easy aging, has a strong impact on the life-span of electricity consumption line security and arrester.
The content of the invention
The defect existed for prior art, the present invention proposes a kind of without using metal oxide resistance, resistant The multi-chamber arrester with series gaps of superior performance.
The technical scheme is that:A kind of multi-chamber arrester with series gaps, including earth plate, supports insulative, line Folder, connection flexible circuit conductor, electric pole plate, lightning-arrest component, wherein, the sub- lower end of supports insulative is fixedly connected with earth plate, upper end with it is upper Battery lead plate is fixedly connected, and wire clamp is fixedly connected by connecting flexible circuit conductor with the upper end of supports insulative and electric pole plate, Top electrode Plate is provided with projection;Lightning-arrest component includes bottom electrode, arc-chutes, full skirt, and lightning-arrest component lower end is fixedly connected with earth plate, taken shelter from the thunder Component upper end is provided with bottom electrode, and discharging gap is formed between bottom electrode and electric pole plate, and multiple arc-chutes and full skirt are equidistant Ground is arranged on lightning-arrest component.
Further, the spacing of arc-chutes is 2.5~3mm.
Further, the spacing of full skirt is 18~24mm.
Further, full skirt is made up of insulating materials.
Further, the spacing of discharging gap is 180~220mm.
The beneficial effect of arrester of the present invention is:
1st, arrester of the present invention is simple in construction, easy for installation;
2nd, arrester of the present invention significantly increases the service life without using metal oxide resistance;
3rd, full skirt is set on lightning-arrest component, increases flashover distance, thoroughly avoid flashover, improve anti-pollution characteristic.
Brief description of the drawings
Fig. 1 is the structural representation of arrester of the present invention.
Shown in being marked in figure:1- earth plates, 2- supports insulatives, 3- wire clamps, 4- connection flexible circuit conductors, 5- electric pole plates, 51- Projection, 6- takes shelter from the thunder component, 61- bottom electrodes, 62- arc-chutes, 63- full skirts, 7- discharging gaps.
Embodiment
Arrester of the present invention is described further with reference to Figure of description and Concrete facts mode.
As shown in figure 1, arrester of the present invention, including earth plate 1, supports insulative 2, wire clamp 3, connection flexible circuit conductor 4, Electric pole plate 5, lightning-arrest component 6, wherein, 2 lower ends of supports insulative are fixedly connected with earth plate 1, and upper end is fixed with electric pole plate 5 Connection, wire clamp 3 is fixedly connected by connecting flexible circuit conductor 4 with the upper end of supports insulative 2 and electric pole plate 5, and electric pole plate 5 is set There is projection 51;Lightning-arrest component 6 includes bottom electrode 61, arc-chutes 62, full skirt 63, and the lower end of component 6 of taking shelter from the thunder is fixed with earth plate 1 to be connected Connect, the lightning-arrest upper end of component 6 is provided with bottom electrode 61, and discharging gap 7, multiple arc extinguishings are formed between bottom electrode 61 and electric pole plate 5 Room 62 and full skirt 63 are equally spacedly arranged on lightning-arrest component 6.
