Yintoni iiYunithi zaMandla aphantsi?

Ndichithe iminyaka elishumi elinesihlanu kwirempu e-DFW phambi kokuba ndiye kwintengiso yezixhobo zenkxaso. Emva phaya sabiza ii-GPU "ziinqwelo" kwaye akukho mntu wayecinga kakhulu ngazo. Uxhume intambo, wabetha iswitshi, walinda ukukhanya okuluhlaza. Ugqibile. Abaqhubi beenqwelo-moya banokuqhuba iinkqubo zabo ngaphandle kokutshisa amafutha e-jet emhlabeni.

Iyunithi yamandla asemhlabeni yenza kanye le nto igama liyithethayo. Inika inqwelomoya amandla ombane ngelixa iinjini zicimile. Ingcamango elula. Akukho lula ukubulawa.

Nantsi into abantu abaninzi abangaphandle koshishino abangayiqondiyo. Iinqwelomoya aziwusebenzisi umbane ofanayo nowendlu yakho. Indawo ophuma kuyo eludongeni inikezela nge-120 volts kwi-60 Hz. Loo maxesha-60 imijikelo ngesekondi nganye-isebenza kakuhle kwizikhenkcezisi kunye nezifudumezi-moya. Kodwa yenza iinjini zombane zibe nzima.

Ubunzima bukubulala kwinqwelomoya. Yonke iponti oyigcinayo kubunzima bemoto yiponti onokuyizalisa ngabakhweli abahlawulayo okanye imithwalo. Ke iinjineli zenqwelomoya zahamba ne400 Hz emva phaya koo-1950. Ngelo xesha, iimotor kunye ne-transformers ziyancipha kakhulu. Injini ye-400 Hz inobunzima besiqingatha sobunzima bemoto obungama-60 Hz kwimveliso yamandla efanayo.

Urhwebo yilahleko yothumelo. Ubuninzi be-frequency ephezulu kuthetha ukuba amandla amaninzi ayopha kumgama. Kodwa ngaphakathi kwinqwelo-moya, imigama mifutshane. Ukonga ubunzima ngaphezu kokuhlawula.

Oku kudala intloko ebuhlungu phantsi. Awukwazi ukuqhuba intambo yolwandiso ukusuka kwisakhiwo se-terminal. Igridi yesikhululo seenqwelomoya isebenza kuma-50 okanye ama-60 Hz njengayo yonke enye indawo. Kukho into ekufuneka iguqule loo mandla osetyenziso ukuya kuma-400 Hz.

Le nto yiGPU.

Inguqulelo elula: iGPU ithatha nawuphi na umthombo wamandla enawo-injini yedizili, umbane osetyenziswayo, ipakethe yebhetri{1}}kwaye ivelisa i-115 volts AC ku-400 Hz. Okanye i-28 volts DC yeenqwelomoya ezincinci. Imveliso ihamba ngentambo enamafutha ukuya kwisixhobo esikufutshane nempumlo yenqwelomoya.

Inguqulelo entsonkothileyo ibandakanya abaguquli bamaza, izilawuli zombane, iisekethe zokhuselo, kunye nezinto ezimalunga newaka ezinokuhamba kakubi ngo-2 AM xa inqwelomoya ilibaziseke kwaye wonke umntu uyakhala.

Ndibone iiyunithi eziqinileyo-ezisuka kwi-ITW GSE ziqhuba ngokugqibeleleyo iminyaka esibhozo kungekho nto ngaphandle kotshintsho lokucoca. Ndikhe ndabona neeyunithi zedizili ezintsha kraca zisitsha kuba umntu ulibele ukujonga into yokupholisa. Izixhobo zilungile kuphela njengabantu abazigcinayo.

Uninzi lwezikhululo zeenqwelo moya zisebenzisa umxube wazo zombini.

Iiyunithi ezilungisiweyo zihlala esangweni. Batsala amandla kwigridi yombane yesikhululo seenqwelomoya kwaye bayiguqule. Intambo ifikelela kwinqwelo-moya ngomngxuma{2}phezulu okwikonkrithi okanye umbhobho ogxunyekwe kufutshane. Akukho kuphelelwa kwedizili. Akukho ndleko zamafutha. Akukho kucwangcisa iintloko. Kodwa uzinikele. Ukuba loo yunithi iyaphuka, ukhangela i-backup yeselula ngelixa abakhweli bebukele ngefestile.

Iiyunithi ezihambayo zikhwela kwiinqwelo ezinamavili. Abasebenzi abaphantsi bazirhuqa ngeetrektara. Imisebenzi yesikolo esidala yayiqhuba yonke into ngale ndlela. Ukubhetyebhetye kuyinyaniso. Ukupaka iinqwelomoya kwindawo ekude engenawo amandla amiselweyo? Roll iyunithi ehambayo ngaphaya. Ukusebenza kwempahla kwicala elikude lentsimi? Isivumelwano esifanayo.

I-downsides nayo iyinyani. Utshisa idizili yokurhuqa ezi zinto ubuye ubuye naphambili. Ukugcwala kwezithuthi kwindlela ephumayo kuthetha amathuba amaninzi eengozi. Kwaye umntu kufuneka alungelelanise ukuba yeyiphi iyunithi eya apho. Loo nto ivakala iyinto engenamsebenzi de ube neenqwelomoya ezingama-200 ngosuku kunye neeyunithi ezintathu phantsi ukulungiselela ukulungiswa.

Ibhulorho-iiyunithi ezinyusiweyo zijinga phantsi kwebhulorho yejethi. Bahamba kunye nebhulorho, ngoko ke intambo ihlala isondele kwisixhobo senqwelomoya. Isisombululo esikrelekrele. Kodwa oomatshini bayabathiya ngenxa yokuba awukwazi ukusevisa iyunithi ngelixa inqwelomoya isesangweni. Zama ukucacisela umphathi wakho ukuba kufuneka ukhuphe ibhulorho ngaphandle kwenkonzo ngexesha lokutyhala emva kwemini.

Kwiminyaka elishumi edlulileyo, ii-GPU{{0}ezinamandla ebhetri ibingumdla wokwazi. Iipakethi ze-Lead-bezinzima kakhulu kwaye azizange zihlale. Unokufumana iinqwelomoya ezintathu okanye ezine ezijikayo ngaphambi kokuba ufune ukutshaja kwakhona.

I-lithium iron phosphate yatshintsha loo nto.

Iiyunithi zebhetri ezintsha zinokubamba ishumi okanye ishumi elinesibini emxinwa-umzimba ujike kwintlawulo enye. Banobunzima obungaphantsi kwesiqingatha somlinganiselo weasidi -enobunzima. Kwaye bathule. Nditsho ndithule nyani. Akukho msindo wedizili. Akukho kuphelelwa. Abasebenzi abaphantsi baqaphela ngoko nangoko.

IJapan Airlines yaqala ukuqhuba ii-GPU zebhetri ye-lithium kwisikhululo seenqwelomoya saseMatsuyama kulo nyaka uphelileyo. Izizathu zabo ezichaziweyo yayikukuncitshiswa kokukhutshwa kwezinto ezikhutshwayo kunye nengxolo. Kodwa ndiyakrokrela ukuba oyena mqhubi ibiziindleko zokuyigcina. Iinjini ze-diesel zifuna utshintsho lwe-oyile, ukutshintshwa kohluzo, ukucocwa kwe-injector. Iipakethi zebhetri azifuni nto.

I-AERO Specialties ithengisa iyunithi kunye neeseli ze-lithium iron phosphate ezingenayo i-cobalt. Ibalulekile loo nto kuba ikhonkco lobonelelo nge-cobalt lubugqwirha{1}}ngokwemigaqo nangolungiselelo. Iibhetri zikwatshintshela kwezinye izixhobo ezisemhlabeni xa zingakwazi ukumelana nomsebenzi ophezulu-zifuna iGPU kwakhona. Okwesibini-ukusetyenziswa kobomi. Smart.

I-Start Pac ikhona kule nto ukususela ngo-1997. UJim Wurth, omnye wabasunguli, wayengumqhubi we-Eastern Airlines ohamba ngeenqwelo-moya emva kokuthatha umhlalaphantsi. Ibali liya kuthi wabambeka kwindawo ekude xa ibhetri yakhe ye-MD500 ingatshoni kwimozulu ebandayo. Wenza iyunithi yakhe yokuqala. Umfazi wakhe uJudith walibona ithuba leshishini. Kwiminyaka engamashumi amabini{6}esihlanu emva koko bathumele ngaphezulu kwe50,000 yeeyunithi.

Iiyunithi zabo ze-lithium eziphathwayo zinobunzima beekhilogram ezilishumi. Shumi. Ungaphosa enye kwindawo yempahla njenge-inshurensi. Abaqhubi beenqwelo-moya ababhabha kwizikhululo zeenqwelomoya abazaziyo bayabathanda.

IBoeing 737 okanye iAirbus A320 idinga uqhagamshelo lwe-90 kVA enye. IBoeing 777 idinga ezimbini. Isixhobo kumzimba omxinwa{6} sihlala malunga neemitha ezimbini ukusuka emhlabeni. Ububanzi-imizimba bubabeka kufutshane neemitha ezintathu, ngoko udinga ileli.

Ukuthoba ngaphantsi kuyingozi. Ukuhlawulela ngaphezulu umthamo ongasidingiyo yinkcitho nje.

Ndikhe ndabukela abaqhubi bethenga eyona yunithi inkulu ekhoyo kuba bacinge ukuba iya kugubungela yonke into. Emva koko bakhalazela ukusetyenziswa kwamafutha okanye amaxesha okutshaja. Ufuna isixhobo esifanelekileyo, hayi esona sixhobo sikhulu.

Isikhululo seenqwelomoya saseZurich sipapashe idatha kwiminyaka embalwa emva sithelekisa izinto ezikhutshwayo ezivela kwiiyunithi zamandla ancedisayo kwinqwelomoya ngokuchasene namandla aphantsi. I-APU ivelisa malunga namaxesha alishumi ngaphezulu kwe-CO2 ngeyure. Amaxesha alishumi.

Ulawulo lwebhetri lwe-European Union lufuna ukuba abavelisi babhengeze imveliso yekhabhoni. Oko kuya kutyhala izigqibo zokuthengwa kwempahla. Iinkampani zeenqwelomoya kunye nezikhululo zeenqwelo moya zokulandelela umda we-3 ukukhutshwa zifuna le datha.

IiGPU zedizili azihambi ngomso. Kodwa ulwalathiso lucacile. Wonke umenzi omkhulu wandisa imigca yemveliso yombane kunye nebhetri. ITW GSE, TLD, AERO Specialties-zonke.

Khangela iimfuno zakho zokwenyani kuqala. Mangaphi amasango? Zeziphi iintlobo zeenqwelomoya? Zingaphi iijika ngemini? Ingaba isiseko sakho sombane sijongeka njani?

Amacandelo elizwe aqinileyo-ayavakala kumasango{1}}ezendlela aphezulu anamandla aluncedo. Iiyunithi zebhetri zisebenza kakuhle kwizitendi ezikude okanye kwimisebenzi apho ungakwazi ukuqhuba iziseko zombane ngokulula. Idizili isenayo indawo yokugcina amandla okanye iindawo ezinegridi ezingathembekanga.

Musa ukuthenga ngokusekelwe kwi-spec sheet kuphela. Thetha nabaqhubi abasebenzisa izixhobo ezifanayo. Buza malunga neendlela zokungaphumeleli kunye nokufumaneka kweendawo. Iyunithi esebenza kakuhle kwindawo yovavanyo yomenzi inokusokola kubushushu behlobo lasePhoenix okanye ingqele yasebusika yaseMinneapolis.

Nebhajethi yoqeqesho. Ndibone izixhobo ezibiza imali eninzi zonakele kuba akukho mntu ufundise ii-agent ze-ramp indlela yokudibanisa kakuhle intambo. I-interlock LED ikhona ngesizathu.
