Bjalo ka sedirišwa sa motheo tšhemong ya go ela mohlagase, kgopolo ya go hlama ya sedirišwa sa go hlahloba gagamalo e laola ka go lebanya go botega ga yona, go dirišwa gabonolo le go bona e sa le pele ga thekinolotši. Kgahlanong le morago ga tlhabollo ya ka pela ya ditshepedišo tša mohlagase, go itirela ga intasteri, maatla a mafsa, le digridi tše bohlale, tlhamo ya bahlahlobi ba gagamalo ba sebjalebjale ga e sa lekanyeletšwa go mešomo ya motheo ya go ela gagamalo. Go e na le moo, e lebišitše tlhokomelo go dikarolo tše nne tša motheo: go nepagala, polokego, bohlale le go fetofetoga le maemo, mola gape go elwa hloko boitemogelo bja modiriši le bokgoni bja go boeletšwa ga theknolotši.
1. Go nepagala: Lefsika la sekhutlo la go botega ga tekanyo .
The primary task of a voltage tester is to provide high-precision measurement results, which is the fundamental starting point of its design. From a circuit perspective, designers must select the appropriate sensor technology based on the target measurement range, such as low voltage (0-1000V), medium voltage (1kV-35kV), or high voltage (>35KV). Ka mohlala, phahameng - nepahetseng resistive dividers kapa gagamalo ditransfoma (PTS) ba tloaelehileng sebediswa ka tlaase-gagamalo maemo a, ha phahameng-gagamalo maemo a itšetlehile ka capacitive dividers kapa Optical gagamalo disensara (OVT) ho fokotsa pontšo attenuation le tšitiso.
Mabapi le moralo wa potoloho, phahameng-di-amplifiers tsa tshebetso tse nepahetseng, 24-bit σ-Δ analoge-go -diphetolelo tsa dijithale (di-adc), le tlaase-dimmojule tsa taolo ya matla a noise ke senotlolo. Ya pele e netefatša go godišwa ga mothalo ga matshwao a go fokola, mola ya morago, ge e fetolela digasefase tša analoge go matshwao a dijithale ka godimo-ADC ya tharollo, e ka swara go fetofetoga ga millivolt goba gaešita le microvolt. Phepelo ya mohlagase ya fase-lešata e thibela ripple ya yona go šitišana le dipoelo tša go ela. Go feta fao, dialgoritmo tša tefo ya themperetšha le mekgwa ya go lekanya (bjalo ka pre-calibration le mosediriši-side automatic calibration) di nepagetše gape bakeng sa diphošo tšeo di hlolwago ke themperetšha ya tikologo le go tšofala ga dikarolo, go boloka go nepagala ka kakaretšo ka gare ga ±0.1% goba gaešita le ±0.05% (bakeng sa dika tša maemo a godimo).
2. Polokego: Mogala wa Bophelo ka godimo-maemo a gagamalo a gagamalo .
Bahlahlobi ba gagamalo gantši ba dirišetšwa go dira diteko tša didirišwa tše di phelago, gomme tlhamo ya bona ya tšhireletšego e tswalana ka go lebanya le tšhireletšego ya bao ba šomago. Bakeng sa maemo a go fapana a gagamalo, batšweletši ba swanetše go kgomarela maemo a go ikarola a mohlagase a go tia (go swana le IEC 61010 le GB 4793) le go phethagatša mekgwa ye mentši ya tšhireletšo go hlola "lepheko la polokego."
For low-voltage (≤1000V) applications, an insulated casing (such as ABS + PC flame-retardant material, with a withstand voltage rating of ≥3kV) and a double insulation structure (basic insulation + supplementary insulation) are essential. For medium- and high-voltage (>1KV) dikopo, phahameng-gagamalo ho itšehla thajana diprobe kapa faeba -optic phetiso thekenoloji ba bohlokwa. Ka mohlala, ba bang ba phahameng-gagamalo bahlahlobi ba fetola phahameng-gagamalo matshwao ba tlaase-gagamalo matshwao a sebelisa capacitive gagamalo divider. Pontšo ena e ka nako eo fetisoa ka faeba Optical (matshwao a optical ke non- conductive) ho ADC modula ka tlaase-gagamalo lehlakoreng, ka ho feletseng severing kgokelo motlakase pakeng tsa phahameng{10}}galase potoloho le tshebetso ya tshebetso. Go feta fao, tšhireletšo ya gagamalo ya go feta tekanyo (OVP), tšhireletšo ya go feta tekanyo (OCP), le dipotologo tša tšhireletšo ya potologo tše kopana-di hlokomela matshwao a go tsenya ka nako ya nnete. Ge moedi o fetilwe (mohlala, gagamalo ya ka pela e feta 120% ya legoro), potologo ya go ela e kgaolwa ka pela gomme alamo (mamelwang-ya go bona) e hlohleletša go thibela tshenyo ya didirišwa goba kgobalo ya motho ka noši.
3. Bohlale: Go tloga go "Kgoboketšo ya Datha" go ya go "Thekgo ya Phetho".
Ka go tsenelela ga Inthanete ya Dilo (IoT) le theknolotši ya dikhomphutha tša mošito, bahlahlobi ba gagamalo ba sebjalebjale ba tšwelela go tšwa go "didirišwa tša go ela tše tee" go ya go "ditheminali tše bohlale tša go hlahloba bolwetši." Moralo wa yona o bohlale o bonagala kudu ka dikarolo tše tharo:
Pele, localized bohlale ya data tshebetso. A a hahiloeng-ka microcontroller (MCU) kapa tlaase-Power processor (e kang Arm Cortex-M letoto la lihlooho tse) sekaseka dibopeho tsa maqhubu a gagamalo (joaloka dikahare harmonic, ho ruruha / sags, le flicker) ka nako ya sebele. E ntšha ditekanyetšo tša semelo ka go šomiša algorithm ya FFT (Fast Fourier Transform), yeo e ntšhago thwii diphetho tša go swana le "Tlhahlobo ya Botsitso bja gagamalo" le "e ka ba meelo ya polokego e fetilwe" go e na le go no fa dikelo tša dipalo tše tala.
Sa bobedi, bonolo motho-Tšhomišano ya khomphutha. A mmala LCD touchscreen nka sebaka sa setso analoge limithara tse kapa diphaephe dijithale, intuitively bontša gagamalo boleng, waveforms, mekhoa histori, le dikhoutu molato. Mojule wa FI wa Bluetooth/Wi-o thekga kgokagano go ditirišo tša sellathekeng goba diforamo tša leru, go kgontšha go hlokomela ka kgole le polokelo ya data (mohlala, go rekota go fetofetoga ga gagamalo mo diiri tše 24 tše di fetilego) bakeng sa tshekatsheko ya ka morago.
Sa boraro, boemo-go fetofetoga le maemo a itšego. Ka hahiloeng-ka multi{3}} litšobotsi tsa ho switjha mokgwa wa (tse kang AC / DC gagamalo tekanyo le jarolla ka ho iketsa fapaneng phetolo), mohlahlobi ka ka tsela e iketsang optimize tekanyo ditekanyetos e thehiloeng litšobotsi tsa ntho ea teko (joaloka tsitsitseng DC gagamalo ya DC tjhaja seteishene kapa 50Hz AC gagamalo ya matla a keriti). Ba bang ba phahameng-bofelo ba end le bona ba ka hlwaya mekgwa e tloaelehileng phoso (joaloka gagamalo feto-fetoga le maemo bakoang ke ikopanye le ikopanye le) le fana ka tshwanelanang tharollo ya mathata ditshitshinyo.
4. Boemo bja go fetofetoga le maemo: Go tloga go morero wa kakaretšo go ya go go dira dilo ka go ithatela .
Dinyakwa tša go dira diteko tša gagamalo di fapana kudu go ralala le diintasteri, go nyaka gore batšweletši ba šome gabotse go dira gore dikarolo tša setšweletšwa di šome gabotse bakeng sa maemo a itšego. Mohlala, ka lefapheng la tshepedišo ya mohlagase le tlhokomelo, bahlahlobi ba swanetše go ba le tekanyo ya go ela ye e nabilego (mohlala, 0.1v-1000V AC/DC) le go ganetša ga tšhitišo ye maatla ya mohlagase wa makenete (yeo e sepelelanago le maemo a EMC sehlopha sa B) go lebeletšana le tikologo ye e raraganego ya mohlagase wa makenete ya diteišene tše nnyane. Ka eneji e ncha (photovoltaic / phefo matla) maemo a, ba lokela ho tšehetsa DC phahameng gagamalo tekanyo (mohlala, 1500V PV khoele gagamalo) le thusa ka and analysis ya MPPT (maximum matla ntlha latedisa) ditekanyetos. Ka liindasteri jarolla ka ho iketsa tlhahiso mela, miniaturization (mohlala, portability), karabelo e potlakileng (nako ya tekanyo<100ms), and IP65 protection (dust and water resistance) are key specifications. In addition, modular design concepts are becoming increasingly popular. Through pluggable functional modules (such as high-precision current probes and temperature sensor interfaces), users can expand the tester's functionality based on their actual needs, avoiding the increased costs of redundant functions or the impact of missing functions on efficiency.
Mafetšo
Kgopolo ya go hlama ya mohlahlobi wa gagamalo gabotse ke tiro ya go lekalekanya magareng ga "diparamethara tša sethekniki" le "dinyakwa tša modiriši": go nepagala ke mola wa fase wa tekanyo ya mahlale, polokego ke mola wo mohwibidu wo o sa kwanantšhego, bohlale ke tlhahlo ya kaonafatšo ya intasteri, gomme go kgona go fetofetoga le maemo go maemo a itšego ke senotlelo sa katlego ya mmaraka. Nakong e tlago, ka tirišo ya didirišwa tše mpsha (tše bjalo ka di-semiconductor tša di-semiconductor) le dialgoritmo tše difsa (tše bjalo ka dika tša go bolela e sa le pele ka molato wa AI), bahlahlobi ba gagamalo ba tla tšwela pele go ya go "go nepagala mo gogolo, tšhireletšego e kgolo, le kwešišo e kgolo ya maemo a itšego," e lego molekane yo a sa šitišego yo bohlale mafapheng a matla le matla.
