When the leakage current of spark gap main body 102 is acquired by non-contact current sensor, it is not
Directly contact with spark gap main body 102 and arrester ground line so that detection part is divided completely with lightning-arrest position
From, it does not interfere with each other, it is ensured that drop-type arrester 100 can be with stable operation.Meanwhile, signal is used to amplify
Circuit, A/D modular converter and logic controller (PLC or CPU), by non-contact current sensor collection
Spark gap leakage current, amplify through signal, after the process of mould revolution and logic controller, both can pass through
Display screen and alarm show and Realtime Alerts in real time.At the same time it can also be what dependence was connected with logic controller
The data of leakage current of an arrester are stored by data memory module, in order to inquiry in good time and analysis spark gap
The record data produced during history run, and analysis result is processed in time, it is to avoid accident
Occur.
Drop-type arrester also includes that dust clears up system, and dust cleaning system includes the first dust stratification detection dress
Put, the second dust stratification detects device and dust blow device, and dust blow device includes being swept into device of air 11,
In the present embodiment, being swept into device of air can be supply fan or inlet air compressor, is swept into device of air
Defecator 12 is set at the air inlet of 11, be swept into device of air 11 be arranged at PCB 2 electricity
The cleaning pipeline 13 of circuit component 19 installed surface side connects, and cleans on pipeline 13 also at multiple components
19 be arranged over, arranges multi-disc bimetallic at each self adaptation gas outlet 14 at multiple self adaptation gas outlet 14
Sheet 15, the bimetal leaf 15 at each self adaptation gas outlet 14 is when bimetal leaf 15 is in relatively cold state
Self adaptation gas outlet 14 is closed, when bimetal leaf 15 is in relatively Warm status to self adaptation gas outlet 14
Lateral direction bends, and is opened self adaptation gas outlet 14, 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, element radiating
Sheet is made up of multiple fin monomers 16, electric insulation between multiple fin monomers 16, the first capacitance measurement
Device is connected with comparator and to comparator feedback actual measurement capacitance, comparator is also connected with memorizer, memorizer
Middle Memory Reference capacitance, reference capacitance value is multiple fin monomers when element radiating sheet non-accumulation dust
Capacitance between 16, when surveying capacitance beyond the threshold value set so that reference capacitance value is as the criterion, clearly
Sweep into device of air 11 to start, through filtered air via the self adaptation gas outlet 14 cleaned on pipeline 13
Blowout, cleans component 19, and dirty air is discharged in housing 11 through exhaust outlet 20.
Second dust stratification detection device light-beam generator is arranged on the circuit elements in PCB 2 with at least one
The mirror surface 17 of position between part 19, it is internal that light-beam generator is arranged on housing 1, light-beam generator with
Rectilinear light beam is transmitted into mirror surface 17 by fixing angle, and after being reflected minute surface 17 reflection, light beam is thrown
It is mapped to be provided with on the photosensitive switch 18 within housing 1, 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, at bimetal leaf
15 bend to self adaptation gas outlet 14 lateral direction, by 14 dozens, self adaptation gas outlet when being in relatively Warm status
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；
So that the area of each self adaptation gas outlet 14 is along with the element below self adaptation gas outlet 14
Temperature is different and different.Because for the element that temperature is the highest, its area of dissipation can be designed to the biggest, or dissipates
Heat surface partly is more conducive to the exchange of heat, but the structure being exactly more conducive to heat to exchange also is
Air flowing change can be caused more acutely or to make air pass through thinner gap, and this structure is the most favourable
In generation and the increase of dust stratification, the dust accumulated after the identical time is the most, just with more cleaning when
Many air mass flows are cleared up.
When fin accumulation dust is more when, the gap between fin can reduce, and fin is as one
The electric capacity of individual entirety can diminish, so when electric capacity is varied down to certain value when, may mean that dust accumulates
Arrive certain stage, so needing to clear up dust.
When PCB 2 and component 19 dust stratification are more when, the dust stratification on mirror surface 17 is also
More, when dust stratification is more when, dust can produce obvious diffuse-reflectance effect, weakens reflection greatly
The direct reflection effect of minute surface 17, can cause photosensitive switch 18 cannot receive the light intensity of sufficient intensity with quilt
Trigger.The automatic monitoring for element surface dust stratification degree is also achieved by another mode, thus aobvious
Improving of writing element surface dust stratification is more and the short circuit that causes or heat radiation are smooth and element that is that cause burns
Ruin problem.
By arranging capacitance detecting and light detection two ways, can backup each other, to guarantee when dust accumulates
To dust cleaning system when of certain stage 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 when some surface attachment after dust, after particularly dust accumulation is more, it will occur significantly
Diffuse-reflectance.Thus when having improve dust and free from dust or the when that dust being many and dust is few, photosensitive switch
The discrimination of 18 light intensity being able to receive that, improves the reliability for light-intensity test, reduces by mistake
The probability started.
Particularly, fin monomer 16 is arranged on an insulating thermal conductor 23, each fin monomer
Between 16, the bearing of trend along diffusion sheet is split.
Insulating thermal conductor 23 can be attachment insulating barrier on metal material, is significantly reducing heat conductivility
In the case of so that each fin monomer 16 mutually insulated, so that structure between each monomer of fin
Become electric capacity.By making each fin split along bearing of trend, permissible between each fin monomer 16
Independent composition electric capacity, it is simple to wiring.
Particularly, the quantity of the bimetal leaf 15 at each self adaptation gas outlet 14 is 6.Double gold
Belonging to sheet 15 and include active layers and passive layer, active layers is manganin manganin alloy, and the material of passive layer is mainly nickel
Ferroalloy.
When the quantity of bimetal leaf 15 is 6 when, in each bimetal leaf 15, laterally restrict tension force
The most less, so that bimetal leaf 15 forms bigger flexural deformation, the quantity of sheet metal foot
More than enough, it is not necessary to be further added by the quantity of sheet metal to reduce the reliability of system.
Bimetal leaf 15 uses monel as active layers, and its deformation quantity is relatively big, thus obtains brighter
Aobvious 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, as
Fruit is cleared up not in time, it will causes element radiating not smooth, thus reduces 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 reality between fin monomer away from
Defection declines, the air of the non-conductor as electricity between metal fin, also has shared by partial air
Space replaced by dust, so the electric capacity between fin monomer can along with the accumulation of dust step by step
Decline.When the low lower limit to threshold value of capacitance, start and be swept into device of air.
In addition to this detection mode, it is also provided with the mode of light detection, when dust amasss on mirror surface
Tired more when, the reflectance of direct reflection can be reduced, reduce the light that photosensitive switch can receive
According to intensity, photosensitive switch sensing is less than reflection light, then photosensitive switch Guan Bi, startup cleans air inlet dress automatically
Put.
It is swept into after device of air starts and absorbs the most filtered cleaned air from the external world, send into and clean pipeline
In.Shape is altered in steps owing to the bimetal leaf at self adaptation gas outlet is as variations in temperature, so
Self adaptation gas outlet now has been opened, and, the self adaptation gas outlet above hotter element is beaten
Opening bigger, the self adaptation gas outlet above the most colder element is opened less, so that totally empty
The flow of gas can be different according to the different temperatures of element distribution, with improve cleaned air utilization imitate
Rate.Can allow be swept into after device of air first blows the very first time and be automatically switched off, the such as very first time can be half point
Clock.Then second time that waited allows and is suspended in the ash fall in enclosure interior space, because while self adaptation goes out
The dust of component surface is blown afloat by giving vent to anger of QI KOU, and constantly to enclosure interior space make-up air,
Saying from main trend, the air being mixed with dust can be discharged from exhaust outlet, but cannot guarantee that certain time it
After, the air being mixed with dust will all be discharged from enclosure interior space.So after blowing over a period of time,
The air in space in housing, is still the air being mixed with a small amount of dust in fact, so needing to wait for a period of time,
Dust in air is allowed to settle.Such as second time can be 3 minutes or 2 minutes.Ash fall in housing
Afterwards, then detect electric capacity, if remaining less than threshold value, then continue to clean, the most then
So the most repeatedly, so that the dust on element and circuit board is cleaned up.
