Description
Technical field
The present invention relates to a kind of arrester with series gaps.
Background technology
When the operation principle of lightning arrester is impacted for being subject to lightning current when circuit, electric current is by the electric discharge of discharging gap up and down on insulator.And after the step-down of zinc oxide arrester resistor disc is filtered, aftercurrent is imported the earth by tower grounding.Existing all be two annulus, be added in insulator two ends, its advantage is not by the restriction in direction, even if electric discharge ring rotates also can not change arcing distance.But its shortcoming be from insulator umbrella leaf too close to, easily cause insulator umbrella leaf burn to dodge when lightning current is excessive, and destroy insulator, affect lightning arrester useful life and release lightning current effect.Existing annulus is all made of aluminum simultaneously, and it is all poor that resistance to electric arc burns poor performance, corrosion resistance and ageing resistance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of long service life, good conductivity, light weight, corrosion-resistant, aging-resistant arrester with series gaps.
For solving the problem, the present invention adopts following technical scheme: a kind of arrester with series gaps, comprise lightning arrester main body, and the insulator be arranged in lightning arrester main body, and upper discharge lever on the insulator and lower discharge lever are set, described upper discharge lever and lower discharge lever are oppositely arranged and form air gap between upper discharge lever and lower discharge lever; Gap between described upper discharge lever and lower discharge lever is fixing on the insulator; Described upper discharge lever and lower discharge lever 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%; The shape of described carbon fiber is bar-shaped, circular, octangle, ellipse or Long Circle.
As preferably, described upper discharge lever and lower discharge lever all adopt compression molding.
As preferably, described insulator be provided with pressing plate between upper discharge lever and lower discharge lever and be connected, described pressing plate adopts the inner surface of zigzag fashion.
As preferably, described pressing plate adopts 6 millimeters thick white steel plates.
As preferably, described lightning arrester main body is connected gold utensil with being provided with between insulator.
As preferably, between described lightning arrester main body and contiguous block, be provided with split pin.
As preferably, described arrester with series gaps entirety is all-sealed structure, described arrester with series gaps is also provided with resistor disc and insulating cylinder, high density liquid autovulcanization silicon rubber is filled with between resistor disc and insulating cylinder, whole product becomes to be integrated from inside to outside, sealing and explosion-proof performance the are had improvement of matter.
The invention has the beneficial effects as follows: owing to adopting upper discharge lever and lower discharge lever, therefore from insulator umbrella leaf distance, can not cause burn blade cause umbrella leaf dodge fall phenomenon occur.Pressing plate adopts 6 millimeters thick white steel plates making zigzag fashion with insulator hardware contact position, just can overcome after tightening like this due on discharge lever and lower discharge lever rotate the problem that the discharging gap that causes changes.Upper discharge lever and lower discharge lever are that carbon fiber adds copper powder and white comminuted steel shot is pressed into, and have 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 feature such as resistance to electric arc, corrosion resistance, ageing-resistant and ultraviolet are strong; Carbon fiber can forever use, and uses 20 years at most under ordinary metallic material natural environment.
