Description
【Technical field】
It the utility model is related to electromechanical appliance field, more particularly to a kind of new external series gap arrester device.
【Background technology】
With the insulating that overhead distribution is transformed, the insulated circuit of traditional design, it is difficult to bear direct thunder or sensing
The effect of thunder, because thunderbolt insulated overhead line can produce huge lightning surge, when it exceedes the pressure-resistant water of wire insulation
Usually (generally higher than 139KV) will find electric field most weak spot along wire and puncture the insulating barrier of wire (generally in insulator
In the range of 30 centimeters of both ends), the breakdown point of aperture size is formed, flashover, last power frequency then are formed to insulator creeping discharge
Electric arc fuses after burning on one point and led to formation metallic short circuit passage after the metal development of insulator root, power frequency arc fixation
Line.The device of the application discharging gap of being connected by nonlinear resistance current limiting element (arrester) with line insulator forms.Can
Effectively solves problem above.The product not only has the good overvoltage releasability of arrester, and in normal operation, tool
There is preferable stability, it is easy for installation, it is applied widely, there is very big promotional value.
【Utility model content】
According to above technical problem, it is good that main purpose of the present utility model is to provide a kind of stability, easy for installation, can have
Effect limitation lightning surge, the new external series gap arrester device to increase the service life.
The technical solution of the utility model is：A kind of new external series gap arrester device, it is characterised in that：It is exhausted including circuit
Edge, bottom plate, arrester, starting rod, the ball electrode of aluminium half, insulating sheath；The line insulator is installed on the left of bottom plate, described
Arrester is arranged on the right side of bottom plate, and upper metal annex of the insulating sheath parcel above line insulator is described
Starting rod is connected with upper metal annex；The ball electrode of aluminium half is arranged on arrester top, the ball electrode of aluminium half with it is described
Starting rod forms external series gap.
Further, the arrester is formed using nonlinear resistance current limiting element.
Further, the described device is installed by support.
Compared with prior art, the utility model has the advantages that：
(1) it is easy for installation, it is not required to change insulator, is also not required to change original circuit design；
(2) there is good nonlinear wind vibration, discharge overvoltage performance sensitive, can with fast shut-off power frequency continued flow,
Effectively limitation lightning surge, so as to protect wire not to be blown, be not required to circuit breaker trip arc extinguishing, will not cause power failure or
Influence power supply quality；
(3) it is not required to break wire insulation, without solving wire sealing waterproof problem, does not interfere with wire mechanical stretching
Energy and service life；
(4) isolation effect of series gap can avoid forming single-phase dead ground connection during failure, nor affect on the safety fortune of circuit
OK.
(5) according to the environmental condition of different regions, the outer discharge gap distance of different series connection is designed, so as to both ensure to discharge
Sensitivity, it is low that and can isolates power-frequency voltage, line loss in normal operation, extends the service life of product, non-maintaining.
(6) insulating sheath is employed, the powered position such as electrode and gland is wrapped in the inside by insulating boot, operation is using more
Safety.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model；
In figure：1 bottom plate, 2 line insulators, 3 arresters, 4 starting rods, the ball electrode of 5 aluminium half, 6 insulating sheaths, 7 tops gold
Belong to annex；
【Embodiment】
The technical solution of the utility model is described in detail below by specific embodiment.
A kind of as shown in figure 1, new external series gap arrester device, it is characterised in that：Including line insulator 2, bottom plate 1,
Arrester 3, starting rod 4, the ball electrode 5 of aluminium half, insulating sheath 6；The line insulator 2 is installed on the left side of bottom plate 1, described lightning-arrest
Device 3 is arranged on the right side of bottom plate 1, and upper metal annex 7 of the parcel of insulating sheath 6 above line insulator 2 is described
Starting rod 4 is connected with upper metal annex 7；The ball electrode 5 of aluminium half is arranged on the top of arrester 3, the ball electrode 5 of aluminium half with
The starting rod 4 forms external series gap.
Further, for the arrester 3 using nonlinear resistance current limiting element composition, arrester is Zinc-Oxide Arrester, is adopted
With high-performance zinc oxide resistor disc, there is good nonlinear wind vibration, discharge overvoltage performance sensitive, can quickly cut
Disconnected power frequency continued flow, effectively limits lightning surge, so as to protect wire not to be blown, is not required to circuit breaker trip arc extinguishing, Bu Huizao
Into power failure or influence power supply quality；
Further, the described device is installed by support.Wherein described support uses 304 stainless steels, prolonged
It is durable.
Protection philosophy：When lightning surge or other failure causes trigger flashover formation metallicity arc discharge short circuit over the ground
When, KA levels power frequency continued flow can be directed directly towards arrester 3 by starting rod 4 on the device by the ball electrode 5 of aluminium half, and by means of
The power frequency continued flow of sinusoidal waveform is transformed into peaked wave by the nonlinear characteristic of arrester 3.Peaked wave electric current has phase before zero passage
When current amplitude is smaller in the long time, meanwhile, the residual voltage of current limiting element cuts down discharge voltage, electric arc moment is extinguished and is reached
Power frequency continued flow is blocked rapidly, reaches the mesh for effectively preventing aerial condutor from fusing (lightning-caused breaking) or tripping by power frequency continued flow high temperature
's.Briefly its arc quenching principle is by the draining ring with insulator series gap, znr current limliting member
The reasonable cooperation of part, the through-flow action in the presence of lightning surge discharge lightning surge energy, it is excessively electric effectively to limit thunder and lightning
Pressure.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it is all contained within the scope of protection of the utility model.
