Detecting system and dust cleaning system.
Fuse switch 100 leaks for a long time cruelly in the external world, and by impacts such as corrosion and dusts, self performance will
Can be affected, after losing efficacy in order to avoid fuse switch 100, this problem of power grid security cannot be ensured,
Fuse switch 100 includes housing 1 and detecting system.This detecting system includes the electricity being connected with power transmission line
Current sensor, and the PCB 2 being arranged in housing 1.Wherein, amperometric can be by electric current
Transformer and digital ammeter composition, for the detection electric current by fusion tube 102.This detecting system is also
Including the signal amplification circuit being located in PCB 2, A/D modular converter and logic controller (PLC
Or CPU), amperometric is electrically connected successively with signal amplification circuit, A/D modular converter and logic controller
Connect.
When logic controller knows the electric current drop-out current more than fusion tube 102 of amperometric, logic control
Device controls alarm and sends alarm, and this explanation fusion tube is the worst or does not meets standard, needs to change, otherwise falls
Formula fuse 100 cannot normally fall.When described logic controller knows the electric current etc. of described amperometric
In zero time, described logic controller controls alarm and sends alarm, and the fuse of this explanation fusion tube 102 disconnects,
Needing to change, otherwise fuse switch 100 cannot normally fall.Wherein, so-called turn-off current refers to
The fuse that can promote fusion tube 102 carries out the minimum current fused.
Fuse switch 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, this reality
Executing in example, being swept into device of air can be supply fan or inlet air compressor, is swept into device of air 11
Air inlet at defecator 12 is set, be swept into device of air 11 be arranged at PCB 2 circuit
The cleaning pipeline 13 of element 19 installed surface side connects, and cleans on pipeline 13 also at multiple components 19
Be arranged over multiple self adaptation gas outlet 14, at each self adaptation gas outlet 14, multi-disc bimetal leaf is set
15, the bimetal leaf 15 at each self adaptation gas outlet 14 will be from when bimetal leaf 15 is in relatively cold state
Adapt to gas outlet 14 close, when bimetal leaf 15 is in relatively Warm status to self adaptation gas outlet 14 outside
To bending, self adaptation gas outlet 14 is opened, and when the temperature of bimetal leaf 15 is the highest when, adaptive
The amplitude answering gas outlet 14 to be 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, cleans
Air intake installation 11 starts, and blows out via the self adaptation gas outlet 14 cleaned on pipeline 13 through filtered air,
Cleaning component 19, 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 when being in relatively Warm status, are 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；Institute
With so that the area of each self adaptation gas outlet 14 is along with the temperature of the element below self adaptation gas outlet 14
Degree is different and different.Because for the element that temperature is the highest, its area of dissipation can be designed to the biggest, or heat radiation
The surface of part is more conducive to the exchange of heat, but being exactly more conducive to the structure of heat exchange is also meeting
Causing air flowing change more acutely or to make air pass through thinner gap, this structure is just more beneficial for
The generation of dust stratification and increase, the dust accumulated after the identical time is the most, just with more cleaning when
Air mass flow clear 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
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 18
The discrimination of the light intensity being able to receive that, improves the reliability for light-intensity test, reduces error starting
Probability.
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 the feelings of heat conductivility
Under condition so that each fin monomer 16 mutually insulated, so that constituting electricity between each monomer of fin
Hold.By making each fin split along bearing of trend, can independent structure between each fin monomer 16
Become 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 ferronickel
Alloy.
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 is enough
Many, 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 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, 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 in pipeline.
Shape is altered in steps owing to the bimetal leaf at self adaptation gas outlet is as variations in temperature, so now
Self adaptation gas outlet opened, and, the self adaptation gas outlet above hotter element is opened
Relatively big, the self adaptation gas outlet above the most colder element is opened less, so that cleaned air
Flow can be different according to the different temperatures of element distribution, to improve the utilization ratio of cleaned air.Can
Being automatically switched off to allow be swept into after device of air first blows the very first time, the such as very first time can be half a minute.So
Rear second time of wait allows and is suspended in the ash fall in enclosure interior space, because while self adaptation gas outlet
Give vent to anger and the dust of component surface is blown afloat, 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, mixed
The air having dust will all be discharged from enclosure interior space.So after blowing over a period of time, in housing
The air in space, in fact or be to be mixed with the air of a small amount of dust, so needing to wait for a period of time, allows sky
Ash fall in gas.Such as second time can be 3 minutes or 2 minutes.After ash fall in housing,
Detect electric capacity again, if remaining less than threshold value, then continue to clean, the most anti-
It is multiple, so that the dust on element and circuit board is cleaned up.
