Brief description of the drawings
Fig. 1 is 1 structure diagram of the utility model embodiment.
Reference numeral includes：
It is grounded knot body 1, deck 2, lower binding post 3, body 4, cable 5, indicator 6, wire clamp 7.
Embodiment
The utility model, Split type structure installation combining form is flexible, preferable to installation space position adaptability.
The utility model includes：It is grounded knot body 1, deck 2, lower binding post 3, body 4, indicator 6 and wire clamp 7.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：As shown in Figure 1, the lower binding post 3 of the downside of knot body 1 connection, 2 front end of deck connection, 4 tail of body are grounded
End, 7 front end link indicator of wire clamp, 6 tail end, the mutual split of this three parts is into absolute construction, moreover, ground connection knot body 1 is top
Portion has the insulator of adhesive structure, and the middle part of body 4 has varistor and arc-chutes respectively, and 4 head end of body is first with indicator 6
End is installed by electrode respectively.
In foregoing, deck 2, lower binding post 3 and wire clamp 7 are electric conductor.
In foregoing, there is articulated connection knot respectively between deck 2 and body 4 and between indicator 6 and wire clamp 7
Structure.
In foregoing, steel ball electrode is installed respectively on 4 head end of body and 6 head end face of indicator.
In foregoing, 4 head end of body has more cell structures with 6 head end of indicator.
In foregoing, 4 inside casting glue stabilization member of body.
In the present embodiment, arrester is made of main body 4, indicator 6, deck 2 and wire clamp 7.Wherein, indicator 6 is
Accessory is matched, indicates the quenching process of arrester.Body 4 is made with indicator 6 of AC gapless metal oxide material；
AC gapless metal oxide has excellent nonlinear wind vibration, and response characteristic is good, big, residual without afterflow, discharge capacity
Force down, suppress overvoltage ability it is strong, it is resistance to it is filthy, anti-aging, from height above sea level constraint, simple in structure, gapless, sealing be tight, the service life
The features such as long.4 encapsulating sealing of body, it is stable and reliable for performance；Deck 2 and wire clamp 7 are high using stainless steel intensity, fixed
Reliably, should not get rusty；Lower binding post 3 is connected by conducting wire with the earth, and arrester original paper can be can be visually seen in outside in the earth
Connection, will not be produced without the mistaken ideas being connected to.Varistor possesses good nonlinear characteristic, therefore is presented under power-frequency voltage
Very high impedance operator ensures the insulation against ground of circuit, and low impedance characteristic is presented under lightning surge can release lightning current,
So as to cut down lightning current peak value to circuit can tolerance range, can not release lightning surge completely.
When mounted, 1 top adhesive of ground connection knot body is fixed is suspended on the lower section of cable 5 to the present embodiment, and lower 3 lower end of binding post is true
Ground connection is protected, it is clamping in lower 3 epimere of binding post with deck 2 moreover, be clamped to beside it with wire clamp 7 on cable 5,
Then, adjust 6 posture of body 4 and indicator respectively so that 4 head end of body and 6 head end of indicator close to.
In the present embodiment, under varistor effect, high resistance shape is presented in normal system operating voltage in arrester
State, only microampere order electric current pass through.Low resistance is just presented in it under the effect of overvoltage high current, so as to limit arrester both ends
Residual voltage.
At work, when overvoltage is produced in 5 circuit of cable, it is first that voltage is added in lightning arrester body 4 to the present embodiment
Potential difference is formed between end and 6 head end of indicator, is started between 6 head end multi-chamber system steel ball electrode of 4 head end of body and indicator
Electric discharge.Big electric arc caused by high-power lightning surge is converted into substantial amounts of small electric arc, is put when reaching between steel ball electrode
During piezoelectric voltage, small electric arc is produced between steel ball electrode, gases at high pressure caused by arc-chutes are by electricity during electric arc discharges
Arc is blown in surrounding air, so that arc extinction, the maximum quenching time is 10ms, has the function that lightning-arrest arc extinguishing.In power frequency
Under voltage, ensure 5 insulation against ground of cable with the synthetic material on the air gap and body 4, when lightning current invades distribution line
When, arrester switchs to working status from state of insulation, and arrester is reduced to base under varistor effect from very high impedance
The substantially zeroed short-circuit condition of this impedance, is quickly all discharged into external system by lightning current, so as to protect distribution line
Safety.And the distribution line that lightning current is all released to external system, which also need be not excessively, worries shadow of the residual voltage to system safety
Ring.
The utility model is used for the insulation for protecting AC input transformation device, is damaged from lightning surge and switching overvoltage
Evil.Suitable for transformer, transmission line of electricity, switchboard, switchgear, electric metering box, vacuum switch, parallel capacitor, rotation
The overvoltage protection such as rotating motor and semiconductor devices.
Disclosed above is only the embodiment of the utility model, and still, the utility model is not limited to this, any ability
What the technical staff in domain can think change should all fall into the scope of protection of the utility model.
