Description

A kind of pure air gap arrester
Technical field
The present invention relates to a kind of pure air gap arrester.
Background technology
When the operation principle of lightning arrester is impacted for being subject to lightning current when circuit, electric current is by the discharging gap electric discharge on insulator.Electric current is by releasing aftercurrent greatly by tower grounding after the step-down of zinc oxide arrester resistor disc.Existing lightning arrester is all adopt to install an angle bar on power transmission sequence shaft tower tower head, zinc oxide arrester installed by angle bar, the upper discharging gap that lightning arrester is installed is hung vertically in above wire, when Lightning Over-voltage, on lightning arrester, directly discharge to wire in gap, wire easily occurs and blows when the high temperature starting the arc.In addition, can swing by nature at the larger wire of thunderstorm weather wind-force, cause wire and discharging gap of arrester distance to swing change with the wind, on lightning arrester, gap and wire can not ensure effective arcing distance, can not play lightning protection effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of long service life, security performance is good, intensity is high, proportion is little, lightweight, and the pure air gap arrester that thermal endurance, corrosion resistance and radiation resistance are strong.
For solving the problem, the present invention adopts following technical scheme: a kind of pure air gap arrester, comprise discharge counter, and the discharge counter frame be arranged on below discharge counter, and the overarm be arranged on below discharge counter frame, and be arranged on the lightning arrester body of overarm below, and the upper gap bar be arranged on below lightning arrester body, and be arranged on overarm below, with lightning arrester body fixing omnipotent hook side by side, and the lower gap bar be arranged on below the bar of gap, and the insulator be arranged on above the bar of lower gap, and be arranged on below insulator, wire installing hole is connected conplane with lower gap bar, described lightning arrester body and insulator be arranged in parallel, Gan Hexia gap, described upper gap bar is pressed into by carbon fiber, high-carbon graphite, copper powder, white comminuted steel shot and electroconductive resin, wherein, percentage by weight shared by carbon fiber is 20%, percentage by weight shared by high-carbon graphite is 40%, percentage by weight shared by copper powder is 5%, percentage by weight shared by white comminuted steel shot is 5%, percentage by weight shared by electroconductive resin is 30%, wherein, the shape of described carbon fiber is bar-shaped, circular, octangle, ellipse or Long Circle.
As preferably, described connection wire installing hole is connected with wire.
As preferably, described pure air gap arrester entirety is all-sealed structure, described pure air gap arrester is also provided with resistor disc and insulating cylinder, is filled with high density liquid autovulcanization silicon rubber between resistor disc and insulating cylinder, and whole product becomes to be integrated from inside to outside.Seal box explosion-proof performance the is had improvement of matter.
The invention has the beneficial effects as follows: described lightning arrester body and insulator be arranged in parallel, being connected firmly, it is accurate to make the upper and lower gap of lightning arrester effectively fix arcing distance, can not swing with the wind, lightning protection effect is better, fabricated structure lightning arrester and insulator and up and down gap package unit can assemble on ground, and once lifted, it is convenient to install, reduce the work high above the ground time, safety and economic benefit obvious.This invention is because lightning arrester and wire are by air insulation, and resistor disc damages without galvanic corrosion, achieves non-maintaining, solves a large amount of repair and maintenance costs.In addition, upper gap bar is also the same with lower gap bar adopts carbon fibre materials, and adds that copper powder and stainless steel powder be pressed into, and has high strength (being 5 times of steel part); The thermal endurance strong high temperature of resistance to more than 2000 degrees Celsius (can); Thermal coefficient of expansion is low; Proportion little (being 1/5 of steel part), lightweight; The features such as resistance to electric arc, corrosion resistance and radiation resistance are strong; Carbon fiber can forever use.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of pure air gap arrester of the present invention.
Embodiment
Consult shown in Fig. 1, a kind of pure air gap arrester, comprise discharge counter 1, and the discharge counter frame 9 be arranged on below discharge counter 1, and the overarm 8 be arranged on below discharge counter frame 9, and the lightning arrester body 2 be arranged on below overarm 8, and the upper gap bar 6 be arranged on below lightning arrester body 2, and be arranged on below overarm 8, with lightning arrester body 2 fixing omnipotent hook 7 side by side, and the lower gap bar 4 be arranged on below gap bar 6, and the insulator 5 be arranged on above lower gap bar 4, and be arranged on below insulator 5, wire installing hole 3 is connected conplane with lower gap bar 4, described upper gap bar 6 and lower gap bar 4 are pressed into by carbon fiber, high-carbon graphite, copper powder, white comminuted steel shot and electroconductive resin, wherein, percentage by weight shared by carbon fiber is 20%, percentage by weight shared by high-carbon graphite is 40%, percentage by weight shared by copper powder is 5%, percentage by weight shared by white comminuted steel shot is 5%, percentage by weight shared by electroconductive resin is 30%, wherein, the shape of described carbon fiber is bar-shaped, circular, octangle, ellipse or Long Circle.Certainly, described upper gap bar 3 and lower gap bar 4, except being carbon fiber, can also be made with materials such as steel, iron, Bai Gang.
