The data of leakage current of an arrester are stored by the data memory module that controller is connected, in order to inquiry in good time and analysis are lightning-arrest
The record data that device produces during history run, and analysis result is processed in time, it is to avoid the generation of accident.
Drop-type arrester also include dust clear up system, dust cleaning system include first dust stratification detection device, second
Dust stratification detection device and dust blow device, dust blow device includes being swept into device of air 11, in the present embodiment, cleans air inlet
Device can be supply fan or inlet air compressor, is swept at the air inlet of device of air 11 and arranges defecator 12, clearly
The cleaning pipeline 13 of the component 19 installed surface side sweeping into device of air 11 and be arranged at PCB 2 connects, and cleans pipeline
Also in multiple self adaptation gas outlet 14 that is arranged over of multiple components 19 on 13, arrange many at each self adaptation gas outlet 14
Sheet bimetal leaf 15, the bimetal leaf 15 at each self adaptation gas outlet 14 when bimetal leaf 15 is in compared with cold state by adaptive
Answer gas outlet 14 to close, bend to self adaptation gas outlet 14 lateral direction when bimetal leaf 15 is in relatively Warm status, by adaptive
Answer gas outlet 14 to open, and when the temperature of bimetal leaf 15 is the highest when, the amplitude that self adaptation gas outlet 14 is opened is the biggest；
First dust stratification detection device includes the first capacitometer for measuring cell fin, and element radiating sheet is by many
Individual fin monomer 16 is constituted, electric insulation between multiple fin monomers 16, the first capacitometer be connected with comparator and to
Comparator feedback actual measurement capacitance, comparator is also connected with memorizer, Memory Reference capacitance in memorizer, and reference capacitance value is
The capacitance between multiple fin monomers 16 when element radiating sheet non-accumulation dust, when actual measurement capacitance is beyond with benchmark electricity
During the threshold value that capacitance is as the criterion and sets, be swept into device of air 11 and start, through filtered air via clean on pipeline 13 from
Adapting to gas outlet 14 blow out, clean component 19, dirty air is discharged in housing 11 through exhaust outlet 20.
Second dust stratification detection device light-beam generator and at least one component 19 being arranged in PCB 2 it
Between the mirror surface 17 of position, it is internal that light-beam generator is arranged on housing 1, light-beam generator with fixing angle by rectilinear light beam
Being transmitted into mirror surface 17, after being reflected minute surface 17 reflection, light beam is projected onto the photosensitive switch 18 being provided with within housing 1
On, when photosensitive switch 18 senses less than reflection light, automatically start and be swept into device of air 11.
Owing to self adaptation gas outlet 14 being closed when bimetal leaf 15 is in relatively cold state, it is in relatively at bimetal leaf 15
Bend to self adaptation gas outlet 14 lateral direction during Warm status, self adaptation gas outlet 14 is opened, and when the temperature of bimetal leaf 15
The when of spending the highest, the amplitude that self adaptation gas outlet 14 is opened is the biggest；So that each self adaptation gas outlet 14
Area is different along with the temperature difference of the element below self adaptation gas outlet 14.Because for the element that temperature is the highest, it dissipates
Hot side is long-pending can be designed to the biggest, or the surface of radiator portion is more conducive to the exchange of heat, but exactly the most beneficially heat
The structure of exchange is also to cause air flowing change more acutely or to make air pass through thinner gap, and this structure is the most more
Being conducive to generation and the increase of dust stratification, the dust accumulated after the identical time is the most, just with more empty cleaning when
Throughput is cleared up.
When fin accumulation dust is more when, the gap between fin can reduce, and fin is as an entirety
Electric capacity can diminish, so when electric capacity is varied down to certain value when, may mean that dust has run up to certain stage, institute
Dust is cleared up with needs.
When PCB 2 and component 19 dust stratification are more when, the dust stratification on mirror surface 17 is the most more, when long-pending
The when that ash being more, dust can produce obvious diffuse-reflectance effect, weakens the direct reflection effect of mirror surface 17 greatly,
Photosensitive switch 18 can be caused cannot to receive the light intensity of sufficient intensity to be triggered.By another mode also achieve for
The automatic monitoring of element surface dust stratification degree, thus significantly improve that element surface dust stratification is more and the short circuit that causes or
The element burnout problems that heat radiation is not smooth and causes.
By arranging capacitance detecting and light detection two ways, can backup each other, to guarantee when dust runs up to necessarily
The when of stage dust cleaning system can system in time, remove the dust of element surface covering.
Laser generator 24 directionality is good, and the light after direct reflection will not occur significantly to dissipate, but works as
After some surface attachment dust, after particularly dust accumulation is more, it will obvious diffuse-reflectance occurs.Thus improve
When having dust and a free from dust or the when that dust being many and dust is few, the discrimination of the light intensity that photosensitive switch 18 is able to receive that,
Improve the reliability for light-intensity test, reduce the probability of error starting.
Particularly, fin monomer 16 is arranged on an insulating thermal conductor 23, edge between each fin monomer 16
The bearing of trend segmentation of diffusion sheet.
Insulating thermal conductor 23 can be attachment insulating barrier on metal material, in the case of significantly reducing heat conductivility,
Make each fin monomer 16 mutually insulated, so that constituting electric capacity between each monomer of fin.By making each
Fin is split along bearing of trend, can independently constitute electric capacity, it is simple to wiring between each fin monomer 16.
Particularly, the quantity of the bimetal leaf 15 at each self adaptation gas outlet 14 is 6.Bimetal leaf 15 includes
Active layers and passive layer, active layers is manganin manganin alloy, and the material of passive layer is mainly dilval.
When the quantity of bimetal leaf 15 is 6 when, the lateral restriction tension force in each bimetal leaf 15 is the most less,
So that bimetal leaf 15 forms bigger flexural deformation, the quantity of sheet metal is the most abundant, it is not necessary to be further added by sheet metal
Quantity with reduce system reliability.
Bimetal leaf 15 uses monel as active layers, and its deformation quantity is relatively big, thus obtains obvious opening
Effect.
Particularly, on the basis of the lower limit of threshold value 0.9 times of capacitance.
On the basis of capacitance when of 0.9 times of capacitance, the dust on electric elements is the most more, if not in time
Cleaning, it will cause element radiating not smooth, thus reduce the serviceability of detection device.
It is as follows that the dust of the present embodiment cleans operating principle:
The when that between component or fin, upper dust stratification being more, the actual range between fin monomer can under
Fall, the air of the non-conductor as electricity between metal fin, also have the space shared by partial air and taken by dust
In generation, so the electric capacity between fin monomer can decline step by step along with the accumulation of dust.When capacitance is low under threshold value
In limited time, startup is swept into device of air.
In addition to this detection mode, it is also provided with the mode of light detection, when dust accumulates relatively on mirror surface
The when of many, the reflectance of direct reflection can be reduced, reduce the intensity of illumination that photosensitive switch can receive, photosensitive switch sense
Should be less than reflection light, then photosensitive switch Guan Bi, automatically start and be swept into device of air.
It is swept into after device of air starts and absorbs the most filtered cleaned air from the external world, send into and clean in pipeline.Due to
Bimetal leaf at self adaptation gas outlet is as variations in temperature and shape is altered in steps, so self adaptation gas outlet now
Open, and, the self adaptation gas outlet above hotter element is opened bigger, above the most colder element
Self adaptation gas outlet is opened less, so that the flow of cleaned air can different the dividing according to the different temperatures of element
Cloth, to improve the utilization ratio of cleaned air.Can allow be swept into after device of air first blows the very first time and be automatically switched off, such as first
Time can be half a minute.Then second time that waited allows and is suspended in the ash fall in enclosure interior space, because while adaptive
Giving vent to anger of gas outlet is answered to be blown afloat by the dust of component surface, and constantly to enclosure interior space make-up air, from becoming greatly
Gesture is said, the air being mixed with dust can be discharged from exhaust outlet, but cannot guarantee that after some time, is mixed with the air of dust
Will all discharge from enclosure interior space.So after blowing over a period of time, the air in space in housing, is still mixed in fact
There is the air of a small amount of dust, so needing to wait for a period of time, allowing dust in air settle.Such as second time can be 3 points
Clock or 2 minutes.After ash fall in housing, then detect electric capacity, if remaining less than threshold value, then continue to clean, as
Fruit there is a need to if then so the most repeatedly so that the dust on element and circuit board is cleaned up.
