In the prior art, insulator and arrester mainly have two kinds of assembling structures：First, insulator, arrester are arranged in parallel
In transmission line of electricity, there is installation and the big technical problem of maintenance difficulties；2nd, insulator and arrester Integral design, and assemble
Discharging gap for electric discharge.Although second of assembling structure, which be easy to safeguard, installs, but is mostly to be in arrester between its electric discharge
Integral structure, this structure has the following disadvantages：First, complicated, assembling is cumbersome, and operating efficiency is low；2nd, complicated knot
Structure can bring insulating barrier easily to go out became uneven phenomenon after vulcanizing, and influence its service life；3rd, because of discharging gap and arrester one
Structure, junction reduces the bending strength of product；4th, discharging gap is nearer apart from full skirt, is easily burnt out during electric discharge.
The content of the invention
The present invention be directed to above-mentioned the deficiencies in the prior art there is provided one kind it is simple in construction, be easily installed maintenance, service life
Long fixed interval (FI) Zinc-Oxide Arrester.
The technical solution adopted for the present invention to solve the technical problems is：A kind of fixed interval (FI) Zinc-Oxide Arrester, including
Lightning arrester body, line insulator, are characterized in also including insulating support, upper sparking electrode and lower sparking electrode, arrester sheet
Body and line insulator are separately positioned on the two ends of insulating support the same side, and upper sparking electrode, lower sparking electrode are separately positioned on
The two ends of insulating support other side, the upper sparking electrode, its upper end is connected with lightning arrester body bottom electrode, and lower end is provided with
Ball discharge one, the lower sparking electrode, its upper end is connected with insulator lower end, and lower end is provided with ball discharge two, ball discharge one
Discharging gap is constituted with ball discharge two.
The insulating support can be made using high-strength insulating materials such as BMCs.In order to ensure after arrester conducting
Thunder and lightning pressure energy discharges in gap location, without along insulating support dielectric surface flashover, must be requested that insulating support has enough creep age distances.
In order to obtain enough creep age distances, at least a piece of increment fin can be provided with the middle part of insulating support.
Further, it can be provided with the middle part of insulating support between at least two panels increment fin, and adjacent increment fin
Away from for 8-15mm.
The highly preferred of increment fin is 15-25mm.
The height and quantity of increment fin reflect creep age distance.In the case where number of fins is certain, increment fin is high
Degree is bigger, and creep age distance is bigger.
The length of discharging gap is adjusted for convenience, horizontal extension portion, ball discharge can be set in upper sparking electrode lower end
One is arranged on extension free end.
Or, horizontal extension portion is set in lower sparking electrode lower end, ball discharge two is arranged on extension free end.
The horizontal extension portion can set some length specifications as needed, be also designed to adjustable length structure, such as set
It is calculated as sleeve type structure etc..
The present invention fixed interval (FI) Zinc-Oxide Arrester compared to the prior art, with beneficial effect following prominent：
（One）Discharging gap moves to the lower end of product, and the electric arc produced during electric discharge will not cause damage to product, effective to ensure
The operation safety of product；
（Two）It is simple in construction, it is cheap beneficial to assembling；
（Three）Discharging gap can be fixed accurately, not influenceed by factors such as external force and construction and installation, therefore can guarantee that arrester sheet
The requirement of body technique parameter, is determined after arcing distance according to parameter, and upper sparking electrode and/or lower sparking electrode are accurately bent
；
（Four）Easy for installation, simple to operate, workman need not adjust discharging gap, upper end and the aerial condutor phase of line insulator
Fixation.
