Voltage drop kye ki?

Voltage drop kwe kukendeera kwa potential y’amasannyalaze okubeerawo nga current ekulukuta okuyita mu conductors mu circuit. Kino kibaawo kubanga kondakita zonna-okuva ku waya z’ekikomo okutuuka ku bitundu bya bbaatule-erina obuziyiza obuzaaliranwa obuwakanya okukulukuta kw’amasannyalaze, okukyusa amasoboza g’amasannyalaze agamu mu bbugumu.

Makanika wa vvulovumenti agwa wakati ku nkola y’amasannyalaze enkulu. Obuziba bwe buyita mu kondakita yenna, busisinkana obuziyiza okuva mu nsengekera ya atomu y’ekintu. Empalirizo eno ey’obuziyiza ereeta okufiirwa kw’amasoboza, okweyoleka ng’okukola ebbugumu n’okukendeera kwa vvulovumenti mu kifo w’ogenda okugeraageranya n’ensibuko.

Etteeka lya Ohm liwa ensengekera y’okubala ku kintu kino: V=I × R. Okugwa kwa vvulovumenti kwenkana akasannyalazo akakubisibwamu obuziyiza. Mu nkola, waya etisse ampere 10 nga zirina 0.5 ohms of resistance ejja kufuna ettondo lya 5-volt along its length.

Enkolagana wakati w’enkyukakyuka zino si ya kusigala. Emigugu gya current egya waggulu gyongera ku vvulovumenti okugwa mu kigerageranyo. Mu ngeri y’emu, obuziyiza bukyuka n’ebintu bya kondakita-Ekika ky’ekintu, omusalaba-ekitundu eky’ekitundu, obuwanvu, n’ebbugumu byonna bikola emirimu. Kondakita z’ekikomo ziraga obuziyiza bwa mita nga 1.68 × 10⁻ 4 Ohm-ku ddiguli 20 , ate aluminiyamu alaga obuziyiza obw’amaanyi ku mita 2.82 × 10⁻⁸ ohm-.

Ebikolwa by’ebbugumu bigatta ensonga. Ku buli ddaala ly’ebbugumu erya diguli 1, okuziyiza kw’ekikomo kulinnya ebitundu 0.393%. Kondakita akola ku 75℃mu kifo kya 20℃afuna roughly 21.5% more resistance, directly increasing voltage drop.

Ku nkola za kasannyalazo ezikyukakyuka, okubala kufuuka kwa maanyi nnyo. AC circuits zirimu impedance okusinga resistance ennongoofu-okugatta resistance ne reactance okuva mu inductive ne capacitive elements. Ensengekera ekyuka n’egenda ku v=i × z, nga Z ekiikirira impedansi. Emiwendo gya reactance gisinziira ku frequency, nga frequency eza waggulu zongera inductive reactance.

Obuwanvu bwa kondakita bukiikirira ensonga esinga okugolola. Obuziyiza bw’amasannyalaze bugeraageranye butereevu n’obuwanvu bwa kondakita-obuwanvu bwa waya bukubisaamu emirundi ebiri obuziyiza era ekivaamu okugwa kwa vvulovumenti. Okudduka kwa waya kwa ffuuti 100 kujja kufuna emirundi ebiri ku vvulovumenti y’okudduka kwa ffuuti 50 wansi w’emigugu egy’amasannyalaze egy’enjawulo.

Wire Gauge ereeta enjawulo nnene mu kukola. Omutindo gwa Wire Gauge (AWG) ogw’Amerika gulaga nti waya y’ekikomo eya AWG 14 erina obuziyiza bwa 2.5 ohms ku buli ffuuti 1,000, ate AWG 10 ekka okutuuka ku 1.0 ohm buli ffuuti 1,000. Buli essatu-gauge ekendeera nga ekubisaamu emirundi ebiri ekitundu ky’omusalaba-ekirala, okusala obuziyiza mu kitundu.

Okulonda ebintu kikulu nnyo. Ekikomo ne aluminiyamu bye bifuga okukozesebwa kw’amasannyalaze olw’omuwendo-obulungi, naye obutambuzi bwabyo bwawukana nnyo. Ekikomo kiwa obuziyiza obutono ebitundu 61% okusinga aluminiyamu, ekitegeeza nti kondakita za aluminiyamu zeetaaga dayamita ennene okukwatagana n’engeri y’okugwa kwa vvulovumenti y’ekikomo.

Load current ekola empalirizo evuga ku voltage drop. Ebyuma ebikuba amperage esingako bikola obuzito bwa vvulovumenti ennene mu kigerageranyo okuyita mu buziyiza bwe bumu. Circuit eyinza okukola mu ngeri ekkirizibwa ku amperes 10 naye efuna obuzibu bwa voltage obuzibu nga load yeeyongera okutuuka ku 30 amperes.

Omutindo gw’okuyungibwa gutera okuleeta ensonga z’okugwa kwa vvulovumenti okubalirira okusubwa. Loose terminal screws, corroded connections, oba crimps ezitamala zikola localized high-ebifo ebiziyiza. Ebitundu bino ebizibu bikola ebbugumu erisukkiridde n’okufiirwa kwa vvulovumenti ebikuŋŋaanyiziddwa mu bifo ebimu okusinga okugabibwa mu buwanvu bwa kondakita.

Enkola za lithium za battery pack zitunuulira okusoomoozebwa okwetongodde okw’okugwa kwa vvulovumenti mu kiseera ky’enzirukanya y’okufulumya ey’amaanyi -Eri wakati. Obuziyiza obw’omunda munda mu butoffaali bwa lithium, mu ngeri entuufu 20-50 milliohms ku butoffaali obw’omutindo ogwa waggulu, bugatta n’okuziyiza okuyungibwa mu paaka yonna. Ensengeka ya 24-cell series nga erina milliohms 40 buli katoffaali ekola 960 milliohms total internal resistance nga tennalowooza ku buziyiza bwa interconnection.

Voltage Drop

Okupima kulina okubaawo mu mbeera y’okutikka. Awatali kutambula kwa current, tewali voltage drop eriwo okupima. Enkulungo enzigule ejja kulaga vvulovumenti y’ensibuko mu kifo kyonna, nga tewali mawulire ga mugaso ku nkola y’enkola wansi w’embeera entuufu ey’okukola.

Enkola entuufu erimu okuteekebwa kwa mita eziwera ku bifo bibiri eby’enjawulo ate nga n’enkulungo ekola ku mugugu ogujjuvu oba ogwa bulijjo. Teeka probe esooka ku source voltage point-Terminal ya battery oba circuit breaker output. Teeka probe eyokubiri ku terminal y’okuyingiza omugugu. Enjawulo ya vvulovumenti wakati w’ebisomeddwa bino ekiikirira okugwa kwa vvulovumenti okubuna ekitundu ekyo eky’enkulungo.

Okusobola okwekenneenya enkola enzijuvu, abakugu bakola ebipimo by’okutonnya kwa vvulovumenti mu bitundu. Kebera okuva ku source okudda ku circuit breaker, breaker okutuuka ku junction box, junction box okutuuka ku final outlet oba load. Enkola eno ezuula ebitundu ebimu ebizibu okusinga okukakasa obutali bumativu mu nkola okutwaliza awamu.

Digital multimeters ziwa obutuufu obumala ku mirimu egisinga obungi, wadde nga mita za RMS entuufu ziwa okusoma okutuufu ennyo ku AC circuits nga tezirina-sinusoidal waveforms. mita za kalaamu zikkiriza okupima kwa kasasiro awatali kutaataaganyizibwa kwa nkulungo, okw’omugaso okubala okugwa kwa vvulovumenti okusuubirwa ku miwendo egyapimwa.

Enkola za bbaatule zeetaaga enkola ez’enjawulo. Okupima voltage drop mu lithium battery configurations kizingiramu okugezesa byombi wansi wa NO-load ne currents ez’enjawulo ezifuluma. Akatoffaali akalamu kayinza okusoma 3.7V nga kaggule-circuit naye nga kakka ku 3.5V wansi w’omuwendo gw’okufulumya 1C, ekiraga nga 0.2V okugwa okuva mu buziyiza obw’omunda.

Enkola ez’omulembe ez’okuddukanya bbaatule zirondoola obutasalako vvulovumenti mu butoffaali ssekinnoomu n’ebitundu ebipakiddwa. Enkola zino zizuula enkola z’okutonnya kwa vvulovumenti eziraga obutoffaali obuvunda, okuyungibwa obubi, oba amasannyalaze agasukkiridde agafuluma nga tegannaba kutondawo nsonga za bukuumi.

Omulimu gw’ekyuma gukendeera nga vvulovumenti y’okugabula egwa wansi w’ebiragiro ebigereddwa. Mota zisika akasannyalazo aka waggulu nga zigezaako okusasula vvulovumenti entono, ekivaako okubuguma okusukkiridde n’okukendeeza ku bulungibwansi. Mota ekoleddwa okukola 240V eyinza okusikiriza amasannyalaze agasingako ebitundu 25% nga gaweereddwa 216V, okwambala okwanguwa ennyo.

Enkola z’okutaasa ziraga ebikolwa ebirabika. Bulbs ezitangaala zizikira mu ngeri eyeetegeerekeka, ate nga ebikondo bya LED biyinza okuwuuma oba okukyusa ebbugumu lya langi. Amataala aga fluorescent gayinza okulemererwa okutandika okwesigamizibwa oba okuvaamu ekitangaala ekikendedde. Obubonero buno bulaga nti voltage drop esukka 5-7% ku nominal supply voltage.

Obuwulize bw’ebyuma eby’amasannyalaze bwawukana nnyo. Kompyuta ne microprocessor-ebyuma ebifugibwa bigumira enkyukakyuka za vvulovumenti obubi-bangi okuggalwa oba okukola obubi nga vvulovumenti zisukka 10%. Ebifuga amakolero biyinza okuvaayo ku bitundu 15% wansi wa vvulovumenti ey’erinnya, okuyimiriza enkola z’okufulumya.

Okukola ebbugumu kyanguyiza n’okugwa kwa vvulovumenti okuyitiridde. Amasoboza agabula mu kondakita gakyusa butereevu mu kufulumya ebbugumu. Circuit eriko 10V drop ku 20A esaasaanya 200 watts nga ebbugumu mu waya okusinga okutuusa amaanyi ago ku load. Ebbugumu erya waggulu ligenda likendeera mu kuziyiza omuliro, ne kireetawo obulabe bw’omuliro.

Battery Packs Lithium .Okukendeeza ku busobozi okuva ku vvulovumenti okugwa wansi w’omugugu. Enkola y’okuddukanya bbaatule eyinza okukomya okufuluma nga tennatuuka nga vvulovumenti egwa ku musingi gw’okusalako, wadde ng’obutoffaali busigala n’omusanvu ogw’amaanyi. Kino "voltage SAG" effect kifuuka kyamanyibwa mu high-discharge applications, okukendeeza ku busobozi obukozesebwa ne 10-20% bw'ogeraageranya n'okufulumya okutono.

Obutoffaali bwa lithium bulaga obubonero bw’okugwa kwa vvulovumenti obutali bwa nnyiriri mu layini okubuna ekipimo kyabwo eky’okufulumya. Okuva ku full charge ku 4.2V buli katoffaali, voltage plateaus around 3.7V for most of the capacity range nga tennagwa mangu wansi wa 3.4V. Wansi w’omugugu omuzito, okuziyiza okw’omunda kuleeta okugwa kwa vvulovumenti okw’enjawulo okuleeta vvulovumenti y’obutoffaali mu kitundu eky’okukka okw’amaanyi nga tekinnatuuka.

Okweraliikirira ku byokwerinda kujja nga voltage drop ereeta current esukkiridde. Ebikozesebwa okuliyirira vvulovumenti entono nga tusikayo amasannyalaze agasingawo agatikka ebyuma ebikuuma circuit. Circuit breakers ziyinza okugwa mu ngeri eteetaagisa, oba ekisinga obubi, kondakita zibuguma okusukka ebbugumu erigereddwa nga obukuumi tebunnakola.

Etteeka ly’amasannyalaze mu ggwanga liwa ebiteeso okusinga ebyetaago ebikakatako ku kkomo ly’okugwa kwa vvulovumenti. NEC 210.19(a)(1) eraga okukomya okugwa kwa vvulovumenti ku nkulungo z’amatabi ku 3% ku vvulovumenti essiddwa ku kifo ekisinga okufuluma. NEC 215.2(a)(4) etegeeza ekkomo erifaanagana eri abawa emmere.

Okugwa kwa vvulovumenti okugatta mu nkulungo zombi ez’okuliisa n’ez’amatabi tekulina kusukka bitundu 5% okusinziira ku NEC Informational Notes. Kino kisobozesa okukyukakyuka mu nteekateeka y’enkola-okugwa kwa 2% feeder kukkiriza okugwa kw’ettabi 3%, oba okugatta okulala okw’enjawulo nga kuliko ebitundu 5% oba wansi.

Ebyuma ebikozesebwa mu byuma bikalimagezi ebirina okulowoozebwako mu ngeri ey’enjawulo. NEC 647.4(d) Ekoma ku kugwa kwa vvulovumenti okutuuka ku 1.5% ku nkulungo z’amatabi eziweereza amaloboozi/vidiyo ezikwatagana oba ebyuma ebifaananako bwe bityo, nga omugatte gw’okugabula n’ettabi nga bigattiddwa awamu tebisukka 2.5%. Ekkomo lino erikakali liziyiza ensonga z’okukola mu byuma ebikozesebwa mu bulamu obwa bulijjo (precision electronics).

Omutindo gw’ensi yonna gwawukana. Ebiragiro bya Bungereza wansi wa BS7671 biraga okugwa kwa vvulovumenti okusingawo okwa 3% ku nkulungo z’amataala (6.9V ku nkola za 230V) ne 5% ku nkulungo endala (11.5V). Etteeka lya Canadian Electrical Code 8-102 mu ngeri y’emu likoma ku nkulungo z’amatabi okutuuka ku bitundu 3% ate omugatte ne gukka okutuuka ku bitundu 5%.

Ku nkola za 120V, 3% yenkana 3.6V maximum drop. Ku 240V circuits, 3% ekkiriza 7.2V okugwa. Ebipimo bino bikakasa nti ebyuma bifuna vvulovumenti emala ekola nga bikoma ku kasasiro w’amasoboza n’okubuguma mu kondakita.

Enkola za bbaatule tezirina mutindo gwa universal voltage drop, nga abakola ebintu bawa enkola-okulungamya okwetongodde. Okuteekebwa kwa bbaatule ya lithium mu ngeri entuufu kutunuulira wansi wa 2-3% okugwa kwa vvulovumenti okuva ku terminal za bbaatule okutikka wansi w’embeera y’okufulumya esinga obunene, wadde ng’okukozesa okw’amaanyi amangi kuyinza okukkiriza okutuuka ku bitundu 5%.

Basic DC Voltage drop okubala kugoberera etteeka lya Ohm butereevu: VD=I × R, nga VD ye voltage drop, I ye current mu amperes, ate R ye resistance ya kondakita mu ohms. Bala obuziyiza bwonna okuva mu bipimo bya waya n’obuwanvu, okukubisaamu amasannyalaze g’omugugu.

Okugeza: enkola ya 12V DC egaba ampere 30 okuyita mu ffuuti 50 eza waya y’ekikomo eya AWG 10 (1.0 ohm buli ffuuti 1,000). Obuziyiza bwonna awamu bwenkana 50/1,000 × 1.0=0.05 ohms. Voltage drop yenkana 30A × 0.05Ω=1.5v, ekiikirira 12.5% ku 12V supply-esukkiridde okusobola okukola obulungi.

Okubala kwa AC okw’omu kitundu kimu-kukozesa enkola efaananako bwetyo n’ensonga y’okutereeza: VD=2 × k × i × d ÷ cm, nga k ye constant ya kondakita (12.9 ku kikomo, 21.2 ku aluminiyamu), i ye kasasiro, d eri emu{{4} ebanga mu bigere mu bigere, ate CM eri ekitundu ekyekulungirivu eky’enkulungo okuva mu kitundu kya milimo ekyekulungirivu.

Enkola ssatu-Enkola za Phase zikyusa ensengekera: VD=1.732 × k × i × d ÷ cm. Ensonga 1.732 (ekikolo kya square ekya 3) ekola enkolagana ya phase mu balanced three-phase loads.

Bayinginiya batera okukola emabega okuva ku kugwa kwa vvulovumenti okukkirizibwa okuzuula obunene bwa kondakita obwetaagisa. Okuddamu okutegeka ensengekera: cm=1.732 × K × I × D ÷ VD ekkiriza okubala ekitundu kya MIL ekyekulungirivu ekitono ekyetaagisa okukuuma vvulovumenti egwa wansi w’omusingi gw’ekigendererwa.

Okubala kwa lithium battery pack voltage kulina okubala ensibuko za resistance eziwera. Obuziyiza bw’obutoffaali obw’omunda bwongera ku buziyiza bw’okuyunga (nickel strips oba busbars) n’okuziyiza waya ez’ebweru. Ku 24-Cell series pack nga okozesa obutoffaali obulina 30mΩ internal resistance, total pack resistance etuuka ku 720mΩ nga tennalowooza ku biyungo. Ku 50A discharge, okugwa kwa vvulovumenti okw’omunda kwokka kwenkana 36V-substantial mu 88.8V pack ey’erinnya.

Mu dizayini y’ebizimbe, okuzuula ebipande by’amasannyalaze wakati okusinga ku nsonda z’ebizimbe kiyinza okusala obuwanvu bwa kondakita omugatte ebitundu 30-40%.

Parallel conductor adduka bulungi okukubisaamu waya cross-ekitundu eky’ekitundu. Okuddukanya kondakita bbiri 10 AWG mu parallel kitondekawo obusobozi obwenkanankana ne waya emu eya 7 AWG, emirundi mingi ku muwendo gw’ebintu ebitono. Buli kkubo erikwatagana litwala ekitundu kya kasasiro, ekikendeeza ku vvulovumenti okukka okutuuka ku bitundu 25% ku ekyo kondakita omu ky’ayinza okufuna.

Okuddaabiriza omutindo gw’okuyungibwa kuziyiza obuzibu bw’okugwa kwa vvulovumenti mu kitundu. Torque entuufu ku terminal screws, anti-ebirungo ebiziyiza okuyungibwa ku biyungo bya aluminiyamu, n’ebikozesebwa ebituufu ebya crimp bikakasa ebiyungo ebitono-ebiziyiza. Ekiyungo ekikalu nga kyongerako 0.1 ohm resistance yokka mu 30A circuit ekola 3V voltage drop ku nsonga eyo emu.

Battery Pack Configurations Balance voltage drop ku nsonga endala ez’okukola dizayini. Series-Enteekateeka ezifaanagana zigaba akasannyalazo mu miguwa egy’enjawulo egy’enjawulo, nga kikendeeza ku kasannyalazo buli katoffaali n’okugwa kwa vvulovumenti ey’omunda. Ensengekera ya 24S2P (obutoffaali 24 mu lunyiriri, emiguwa ebiri egy’enjawulo) ekendeeza ku kitundu ky’amasannyalaze agafuluma okuyita mu buli lunyiriri bw’ogeraageranya ne 24S1p.

Enkola z’okuddukanya bbaatule za lithium zisobola okuliyirira ebikolwa eby’okugwa kwa vvulovumenti okuyita mu kulondoola okw’omulembe. Advanced BMS units zipima voltages z’obutoffaali ssekinnoomu wansi w’omugugu, nga zibala embeera entuufu eya chajingi wadde nga voltage sag. Kino kiziyiza okuggwaawo kw’amazzi agafuluma nga tekinnatuuka era kiyamba okukozesa obusobozi obusobola okukozesebwa.

Lithium battery packs ziraga enjawulo voltage drop characteristics ezawukana ku lead ey’ennono-battery za asidi. Obuziyiza obw’omunda mu butoffaali bwa lithium obw’omutindo buva ku 20-80 milliohms okusinziira ku kemiko y’obutoffaali n’obunene. Obutoffaali bwa LifePO4 butera okulaga obuziyiza obw’omunda obusingako katono (40-80mΩ) bw’ogeraageranya n’obutoffaali bwa NMC (20-50mΩ), wadde nga LifePO4 egaba obulamu obw’enzirukanya ey’oku ntikko.

Enteekateeka y’obutoffaali ekosa nnyo ensengekera ya vvulovumenti egwa. Ebiyungo bya series bikubisaamu voltage nga bikuuma obusobozi bwa current, naye era okugatta resistances ez’omunda. A 24-series pack of 40mΩ cells ekola 960mΩ total internal resistance. Ebiyungo ebikwatagana bikubisaamu obusobozi bwa kasasiro nga bwe bigerageranya obuziyiza obw’omunda-obutoffaali busatu mu parallel bukendeeza ku buziyiza obulungi eri ekitundu kimu kya kusatu eky’obutoffaali bumu.

Omutindo gw’okufulumya gukwata nnyo ku bunene bw’okugwa kwa vvulovumenti. Obutoffaali bwa lithium bulaga obuziyiza obw’omunda obutakyukakyuka okubuna emiwendo gy’okufulumya, ekitegeeza nti vvulovumenti egwa minzaani mu layini ne current. Akatoffaali akalina obuziyiza bwa 40mω kafuna 0.04V okukka ku 1A naye 2.0V okukka ku 50A. Enjawulo eno eya 2V esobola okusika vvulovumenti y’obutoffaali okuva ku 3.7V plateau ey’erinnya okudda mu kitundu eky’okukendeera okw’amaanyi.

Ebikolwa by’ebbugumu byongera ku nsonga z’okugwa kwa vvulovumenti. Lithium cell internal resistance yeeyongera nnyo ku bbugumu eri wansi-etera okukubisaamu emirundi ebiri wakati wa 25℃ne -20℃. Battery pack eraga 5% voltage drop ku room temperature eyinza okufuna 10% voltage drop mu mbeera ya freezing, severely limiting usable capacity.

Okuziyiza okuyungibwa kwongera ku buziyiza obw’omunda obw’obutoffaali. Ebiyungo bya nickel strip wakati w’obutoffaali biyingiza 5-20 milliohms buli kiyungo okusinziira ku buwanvu bw’omuguwa, obuwanvu, n’omutindo gw’okuweta. Okunoonyereza okwakolebwa mu 2024 ku dizayini ya bbaatule kwazuula nti emiguwa gya nickel egyasiigiddwako giriko 0.237Ω omugatte nga girina 11.735V voltage drop ku 50A, ate nga n’ensengeka ya niiki ennongoofu yatuuka ku 0.048Ω n’enjawulo ya 2.82V drop-A kumpi emirundi 5.

Embeera ya chajingi ekwata ku nneeyisa y’okugwa kwa vvulovumenti. Obutoffaali obujjudde obusannyalazo bukuuma vvulovumenti ennywevu wansi w’omugugu ogw’ekigero, naye obutoffaali obufuluma ennyo (wansi wa 20% embeera y’omusannyalazo) bulaga okweyongera kw’okuziyiza okw’omunda. Kino kitondekawo ekikolwa eky’okukulukuta (cascading effect) nga vvulovumenti egwa amangu nga bbaatule ekendeera, ekikendeeza ku busobozi obusobola okukozesebwa mu bitundu 20-30% ebisembayo ku busobozi obugereddwa.

Enkola z’okuddukanya bbaatule zikola emirimu emikulu mu kuddukanya ebikolwa eby’okugwa kwa vvulovumenti. Active cell balancing during charging ekakasa voltages ezifaanagana okuyita mu series-obutoffaali obuyungiddwa, okuziyiza obutoffaali obunafu okukomya omulimu gwa pack. Mu kiseera ky’okufulumya, BMS units zirondoola voltage wansi w’omugugu okuziyiza over-okufulumya cells ssekinnoomu ne bwe pack voltage esigala waggulu cutoff thresholds.

Okukwatagana kw’obutoffaali mu kiseera kya pack assembly kikendeeza ku voltage drop obutakwatagana. Obutoffaali obulina obusobozi obufaanagana, obuziyiza obw’omunda, n’okwefuula-emiwendo gy’okufuuwa gikola mu ngeri y’emu wansi w’omugugu. Obutoffaali obutakwatagana bukola enkyukakyuka za vvulovumenti ezikoma ku pack yonna ku nkola y’obutoffaali obusinga obunafu, okwonoona obusobozi mu butoffaali obw’amaanyi.

Ebikwata ku byuma biyinza okunyooma ddala-Ensi yonna, naddala motor inrush oba capacitor charging currents ezikola voltage drop spikes.

Obubonero bwa voltage drop butera okukoppa ebizibu ebirala eby’amasannyalaze. Amataala agazikira gayinza okulaga okugwa kwa vvulovumenti naye era gayinza n’okulaga ebiyungo ebitali binywevu, okuyingira mu mpeereza etali nnene, oba ensonga z’okugabira abantu ebikozesebwa. Ebipimo bya vvulovumenti ebitegekeddwa wansi w’omugugu byawula wakati w’ebivaako bino.

Battery pack diagnostics zeetaaga enkola ez’enjawulo. Okugezesa obusobozi wansi w’emiwendo gy’okufuluma okufugibwa kiraga obutoffaali obulina obuziyiza obw’omunda obuyitiridde. Akatoffaali akalaga vvulovumenti eya wansi ennyo wansi w’omugugu bw’ogeraageranya ne NO-embeera y’omugugu eraga obuziyiza obw’omunda obugulumivu, nga kyetaagisa okukyusibwa okuzzaawo omulimu gwa pack.

Voltage Drop

Enkola z’amasannyalaze ga RV n’ennyanja zitera okusanga okusoomoozebwa kw’okugwa kwa vvulovumenti. Cable empanvu eva ku bbanka za bbaatule okutuuka ku migugu, ng’egattibwa wamu n’ebyuma ebiwanvu-ebiriwo nga ebyuma ebifuuwa empewo ne microwaves, bikola amatondo ga vvulovumenti omunene. A 30-Foot run ya 10 AWG wire egaba 20 amperes ekka nga 1.2V-problematic mu 12V systems (10% loss) naye nga esobola okuddukanyizibwa mu 24V systems (5% loss).

Ebintu ebiteekebwamu amaanyi g’enjuba birina okubala okugwa kwa vvulovumenti okuva ku bipande okutuuka ku bifuga chajingi n’okuva ku bbaatule okutuuka ku inverters. Ensengekera y’enjuba esangibwa ffuuti 100 okuva ku kifuga ekisannyalazo yeetaaga okukyusakyusa mu ngeri ya kondakita n’obwegendereza. Ku nkola ya 30A, 24V, olugendo lwa ffuuti 200 okudda n’okudda n’okuva mu panels) lwetaaga waya 6 AWG okukuuma wansi wa 2% voltage drop.

Battery packs z'emmotoka ez'amasannyalaze ziraga ekyokulabirako waggulu -Ekivaamu voltage drop scenarios. EV ez’omulembe zikuba 300-400 amperes mu kiseera ky’okusannyalala. Ne 10 milliohms of excess resistance ekola 3-4V drop ku peak current, ekikendeeza ku maanyi agaliwo n’obuwanvu. Abakola ebintu bateeka ssente nnyingi mu kuyungibwa okutono nga bakozesa enkola ya ultrasonic welding ne optimized busbar designs.

Data Center Amasannyalaze Okugabanya Amasannyalaze galaga okugwa kwa vvulovumenti ku bulamu bw’ebyuma. Server power supplies rated for 200-240V Operation experience enyangu okwambala nga voltage enywevu ekka wansi wa 200V. Ebifo bikuuma vvulovumenti egwa wansi wa 2% okukuuma ebyuma eby’ebbeeyi n’okukakasa nti bikola nga byesigika.

Enkola za motor mu makolero ziraga engeri voltage drop gy’ekosaamu productivity. Motoka ya 460V efuna 8% voltage drop efuna 423V zokka. Kino undervoltage kyongera ku current draw nga 9%, ne kivaamu 19% more heat (I2r losses) mu motor windings. Omugatte guno gukendeeza ku bulungibwansi bwa mmotoka ebitundu 3-5% era gwanguyiza okumenyawo okuziyiza (insulation breakdown).

Enkodi y’amasannyalaze mu ggwanga egamba nti ekkomo ku vvulovumenti ekka okutuuka ku bitundu 3% ku nkulungo z’amatabi ate 5% nga zigatta wamu ku feeders ne branch circuits. Ku nkola za 120V, kino kitegeeza obutasussa 3.6V ku circuit ssekinnoomu ne 6V total. Electronics ezikwatagana zeetaaga ekkomo erikakali erya 1.5-2.5%.

Voltage drop yeeyongera mu layini n’obuwanvu bwa kondakita. Obuwanvu bwa waya emirundi ebiri bukubisaamu emirundi ebiri okugwa kwa vvulovumenti wansi w’omugugu gwa kasasiro gwe gumu. Enkolagana eno ey’ekigero kitegeeza nti emisinde gya waya empanvu gyetaaga ebipima waya ebinene okukuuma emitendera gy’okugwa kwa vvulovumenti okukkirizibwa.

Okugwa kwa vvulovumenti okuyitiridde tekutera kuleeta kwonooneka kwa mangu naye kwanguyira okwambala okuyita mu nkola eziwerako. Motoka zibuguma nnyo okuva mu kweyongera kw’okukuba akasannyalazo, ebyuma eby’amasannyalaze bifuna situleesi okuva mu OUT-of-spec voltage, ne bbaatule zibonaabona n’ensonga z’okucaajinga. Okukola okuwangaala nga olina okugwa kwa vvulovumenti enkulu kukendeeza nnyo ku bulamu bw’ebyuma.

Ku circuit za DC, kozesa: Voltage drop=current × resistance. Funa obuziyiza bwa kondakita okuva mu bipande ebipima waya (ohms buli ffuuti 1,000), okukubisaamu obuwanvu obwennyini, olwo emirundi gy’obuwanvu bw’omugugu. Online calculators zinyanguyiza enkola eno ku circuit zombi eza AC ne DC nga zikwata ku waya specifications automatically.
