Description

A kind of series gap metal oxide arrester
Technical field
The utility model is related to field of high-voltage electrical equipment, especially a kind of series gap metal oxide arrester.
Background technology
In power transmission, thunderbolt is subject in multi-thunder area, the tower arm voltage of high tension electric tower can rise when thunderbolt is met It is high.The conventional mode of route protection is in electric substation or power plant end installing arrester, when the transmission and distribution line of the dozens of kilometres that is continuous When road meets with thunderbolt, moment tower arm current potential rises, although in power plant end or electric substation's end installing arrester, but thunderbolt ripple Wanting the several seconds can just arrive at power plant end or electric substation end, therefore before arrester not yet generating function, in electric line Steel tower tower arm current potential rise, strike back insulator, cause defective insulation, cause market occur tripping operation power-off situation.
Utility model content
The utility model provides a kind of series gap metal oxide arrester, tripping operation when can reduce thunderbolt, have a power failure it is several Rate.
The utility model specifically adopts the following technical scheme that realization:
A kind of series gap metal oxide arrester, in electric line, one end of the arrester is metal The electricity of material compressing tablet, the electricity compressing tablet keeps certain the air gap, institute with the equal compressing tablet of the wire of built on stilts electric line Stating arrester includes:Multiple resistor discs, band and the insulation supporting pillar being serially connected, the resistor disc periphery is formed in one Binder, the band is wound on the resistor disc, and electrode, the insulating supporting are drawn in the case where the terminal of the band is provided with Post by the electricity compressing tablet with it is described under draw electrode and combined.
Preferably, also include fixed seat, the tower seat in the fixed seat connection electric line.
Preferably, the fixed seat is zinc-plated fixed seat.
Preferably, the resistor disc is metal oxide resistance.
Preferably, the electricity compressing tablet is ring or the tablet with geometry.
The series gap metal oxide arrester that the utility model is provided, its advantage is:Using line type oxygen Compound arrester, when thunderbolt is to steel tower, because the flashover voltage of the residual voltage ratio insulator of arrester is low, jumps when can reduce thunderbolt Lock, the probability having a power failure;Noted by electric glue between compressing tablet and resistor disc and be integrally bonded structure, when thunderbolt destruction is met with not Can fragment splashing;By installing insulation supporting pillar additional, suspension insulator can be replaced in electric line, save transmission & distribution electric installation Through costly.

Specific embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model is disclosed A part for appearance, it is mainly used to illustrate embodiment, and running of the associated description of specification to explain embodiment can be coordinated former Reason.Coordinate and refer to these contents, those of ordinary skill in the art will be understood that other possible implementation methods and this practicality are new The advantage of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in figure 1, a kind of series gap metal oxide arrester that the present embodiment is proposed, used in electric line In, its one end is the electricity compressing tablet 16 of metal material, and electricity compressing tablet 16 is protected with the equal compressing tablet 21 of the wire of built on stilts electric line 22 Hold the air gap S.Arrester 10 includes the multiple resistor discs 12 being serially connected, and resistor disc 12 is core parts and is metal oxygen Compound resistor disc, resistor disc 12 can have the ability of good C-V characteristic and resistance to transient overvoltage for pressure-sensitive ceramic resistor, And the binder that between each resistor disc 12 is concatenated and whole peripheries of resistor disc 12 are formed in one, and band 13 is wound in resistance To insulate and fixed resistance piece 12 on piece 12, band 13 draws electrode 14 in the case where terminal is provided with, the material of electricity compressing tablet 16 for aluminium or Copper and be ring or the tablet with certain geometrical shape.
In addition, fixed seat 11 is located at another terminal to connect the seat of the tower in electric line, fixed arrester 10 is played Purpose, fixed seat 11 can be zinc-plated fixed seat, fixed seat 11, resistor disc 12, band 13 and under draw electrode 14 be arranged one into The cluster parachute shape insulator 15 of type, to lengthen creepage distance, increases dielectric strength.
The present embodiment has for clearance type circuit Oxide Arrester, i.e. leakage conductor with the wire on electric line Outside concatenation gap, is formed by overcoat Oxide Arrester body and series gap, and its function is used to limit lightning surge Part operation overvoltage.And electric equal compressing tablet is directly integrally bonded structure with resistor disc with glue note, is struck by lightning or transmits electricity when meeting with During line fault electric current, cause pressure to discharge and cause arrester fragmentation, be unlikely to fragment splashing.
Embodiment 2
As shown in Fig. 2 a kind of another embodiment of series gap metal oxide arrester that the present embodiment is proposed, arrester 30 one end is connected with built on stilts electric line 42, and arrester 30 includes the multiple resistor discs 33 being serially connected, resistor disc 32 Be core parts and be metal oxide resistance, resistor disc 32 can for pressure-sensitive ceramic resistor have good C-V characteristic and The binder that between the ability of resistance to transient overvoltage, and the concatenation of each resistor disc 32 and whole peripheries of resistor disc 32 are formed in one, And band 33 is wound on resistor disc 12 with insulation and fixed resistance piece 32, band 33 draws electrode 34 in the case where terminal is provided with, absolutely Edge support column 37 draws electrode 34 with and is combined with electric compressing tablet 36, the other end of insulating supporting post 37 and built on stilts electric line 42 The equal compressing tablet 41 of wire connect.In addition, fixed seat 31 is located at another terminal to connect the seat of the tower in electric line, fixation is played The purpose of arrester 30, fixed seat 31 can be zinc-plated fixed seat.
