Extinguish power frequency arc before relay protection action.The arrester of the present invention can preferably reduce influence of the thunder and lightning to transmission line of electricity,
Improve the Stability and dependability of power system.
As a kind of enforceable mode, refer to shown in Fig. 2, arc extinguishing unit includes the electrode being connected with spiral umbrella disk 5
51 and the rubber layer 52 in the outside of electrode 51 is covered in, electrode 51 has smooth edge, the electrode 51 of adjacent arc extinguishing unit
Spaced formation the air gap, the outside of rubber layer 52 are symmetrical arranged two electric discharge projections 53.
In each arc extinguishing unit, the electric discharge projection 53 of two electric discharge projections 53 arc extinguishing unit adjacent with both sides respectively is mutual
Face and spaced, the formation gap in arcing chamber 54 between two electric discharge projections 53 facing each other.
That is, in each arc extinguishing unit, the electric discharge projection 53 protruded outward is symmetricly set in the center of arc extinguishing unit
Line both sides, and the inner of two electric discharge projections 53 is smaller than its outer end spacing, makes the end of electric discharge projection 53 respectively to both sides
Direction extension where adjacent arc extinguishing unit, to be formed respectively between the electric discharge projection 53 of the arc extinguishing unit adjacent with both sides
Less gap in arcing chamber 54.
More preferably, electrode 51 can be sphere pole, elliptical electrodes, circular electrode, or other have smooth edge
Electrode.The air gap being spaced between electrode 51 is stabilized, and ensure that the reliability of arc extinguishing section.
Electrode 51 is sphere pole in the present embodiment, and sphere pole is partially retained in the rubber layer 52 of insulation, adjacent
The air gap between sphere pole 51 be present, the air gap passes through the gap in arcing chamber 54 that the outside of rubber layer 52 is set and outside sky
Gas connects.Under lightning wave effect, the air gap between sphere pole 51 made of metal is breakdown, electric arc occurs.Thunder and lightning
After ripple acts on, the air between the air gap is heated by the electric arc simultaneously expansion, and electric arc is pushed out the air gap so that arc length increases
Add, temperature reduces, and promotes arc extinction.
Further, can not only be with each arc extinguishing unit pair as shown in figure 1, being arranged grading ring 1 respectively at the both ends of arc extinguishing section
Electric field should be formed, moreover it is possible to make electric discharge more stable.
As a kind of enforceable mode, grading ring 1 is may also set up in the upper end of resistive segments, makes electric discharge more stable.
Further, as shown in Fig. 2 the spacing distance between the electrode 51 of adjacent arc extinguishing unit is more than or equal to 5
Millimeter, and less than or equal to 10 millimeters, the air gap is formed between adjacent electrode 51, because the air gap is smaller, and quantity
More, multiple the air gaps make arc extinguishing section have multiple short air gap.The width of gap in arcing chamber 54 is smaller, and it is more than or equal to 2.5
Millimeter, and less than or equal to 5 millimeters.In arc burning, the air of expanded by heating is smaller from width by electric arc in the air gap
Gap in arcing chamber 54 blow out, make arc extinction.
Further, the cross-sectional area for projection 53 of discharging is gradually reduced from inside to outside, so that electric discharge occurs.
Further, the end for projection 53 of discharging is spherical in shape, makes electric discharge more stable.
As another enforceable mode, arc extinguishing unit includes arc-extinguishing tube and the aerogenesis being attached on the inwall of arc-extinguishing tube
Material layer, gas can be discharged when gas exhausted material layer is heated, that is to say, that arc extinguishing unit can use air-flow arc extinguishing unit.Work as production
Gas material layer is higher than the speed of air expansion by gas velocity during heat, discharged caused by electric arc, so as to the gas energy
Electric arc is blown out.The gas exhausted material layer that gas can be discharged by being set in arc-extinguishing tube belongs to prior art, will not be repeated here.Due to gas
Flow arc extinguishing unit and preferentially used more by airflow function, the easy generating material aging of related components therein, arc extinguishing section for a long time
The structure of weight short air gap.
Further, as shown in figure 3, resistor main body 4 includes epoxy resin cylinder 41 and is stacked and placed on the interior of epoxy resin cylinder 41
Multiple resistor discs 42 in chamber.
As a kind of enforceable mode, resistor disc 42 is matal-oxide resistor piece, in the present embodiment, using zinc oxide electricity
Hinder piece.
The arrester of the present invention, using the resistive segments with zinc oxide resistance sheet and the arc extinguishing section phase with multiple short air gap
The structure mutually connected.Under the operating mode of normal operation circuit, arc extinguishing section bears the additional power-frequency voltage of the overwhelming majority, that is,
Say, multiple short air gap bears line voltage.
Under lightning wave effect, multiple short air gap is breakdown, and lightning surge is applied on zinc oxide resistance sheet so that oxygen
Change the action of zinc resistor disc, the resistance of resistor disc 42 is reduced, and lightning current is let out downwards along zinc oxide resistance sheet and the short air gap of breakdown
It is put into the earth.That is, electric arc punctures along zinc oxide resistance sheet, multiple short air gap and three grading rings 1, now zinc oxide is electric
Resistance piece is in low resistance state, and lightning current is released to the earth by above-mentioned breakdown path.
Lightning wave action time is very short, and when the lightning current on conductive path is decayed, but electric arc does not extinguish, line voltage is applied
The both ends of zinc oxide resistance sheet are added in, zinc oxide resistance sheet recovers to high resistance state, and power frequency continued flow electric current is only milliampere level.By
Recover in the resistance of zinc oxide resistance sheet, freewheel current very little, afterflow electric arc is cut off quickly, and only amplitude is milliampere rank
Power frequency continued flow flows through zinc oxide resistance sheet.In power frequency continued flow zero passage, gap in arcing chamber of the electric arc in multiple short air gap arc extinguishing section
Go out blowout, extinguish.For traditional arrester, arrester proposed by the present invention can be by the amplitude of power frequency continued flow electric current
A milliampere rank is limited in, reduces the power frequency short circuiting arc caused by thunder and lightning punctures gap, and then avoid power frequency continued flow electric current pair
Power network impacts.
When the zinc oxide resistance sheet in arrester is because of phenomena such as longtime running or external factor cause aging, damage, electricity
Hindering the resistance of piece 42 reduces, and freewheel current amplitude reaches kilo-ampere level, or during most serious, resistor disc is short-circuit under thunderbolt state,
Again or resistance is difficult to recover after thunder and lightning wave attenuation.Because multiple short air gap arc extinguishing section has very strong arc extinction performance, work as height
When flowing through short air gap (i.e. the air gap) up to the freewheel current of kilo-ampere rank, the air in the air gap is because of heat caused by electric arc
And expanded by heating, power frequency continued flow electric arc leave from the gap in arcing chamber 54 between sphere pole 51, that is to say, that electric arc is along between arc extinguishing
Gap 54 is released outside gap in arcing chamber 54, and electric arc makes the resistance of electric arc increase, electric arc by being elongated during narrower gap in arcing chamber 54
Temperature reduce, so as to promote arc extinction, cut off power frequency continued flow.
From the foregoing, it will be observed that even if there is short trouble in zinc oxide resistance sheet, because arc extinguishing section has multiple short air gap structure, still
The power frequency continued flow electric arc of kilo-ampere rank can so be extinguished before relay protection acts, avoid the generation of short-circuit trip accident.
Further, resistor main body 4 also includes the crimping armor clamp 43 and two bullets for being sealed on the both ends of epoxy resin cylinder 41
Property part 44, each elastic component 44 are separately positioned between each crimping armor clamp 43 and resistor disc 42.
As shown in figure 1, the end metal fitting 2 of crimping armor clamp 43 and arrester is connected through a screw thread, it is ensured that when lightning wave applies
At the both ends of resistive segments, the resistor disc 42 to stack together can realize effective electrical connection.
In the present embodiment, elastic component 44 is spring.The upper end of spring above acts against crimping gold above
The lower surface of tool 43, its lower end contact is in the upper surface of the resistor disc 42 of the top；The upper end contact of underlying spring exists
The lower surface of the resistor disc 42 of bottom, its lower end act against the upper surface of underlying crimping armor clamp 43.
Further, the spacing distance of adjacent annular umbrella disk 3 is more than or equal to 35 millimeters.The spacer of annular umbrella disk 3
From smaller, it can make arrester that there is larger creepage length.
From the foregoing, it will be observed that the arrester of the present invention, in transmission line of lightning strike, the resistance of resistor disc 42 reduces, and effectively lets out
Lightning current is put, resistor disc 42 can also recover resistance, the power frequency continued flow electric current after limitation lightning wave effect after thunder and lightning wave attenuation
Amplitude, ensure that circuit is struck by lightning.Meanwhile after lightning surge decays, even if the resistor disc 42 in arrester is damaged or lost
Effect, when causing power frequency continued flow amplitude too high, power frequency continued flow can also be effectively cut off before relay protection of power system action, protected
Demonstrate,prove the normal table operation of transmission line of electricity.
