Yuniti z’amasannyalaze g’oku ttaka kye ki?

Namala emyaka kkumi n’etaano ku ramp ku DFW nga sinnagenda mu kutunda ebyuma ebiwanirira ku ttaka. Mu kiseera ekyo GPUs twaziyita "the carts" era tewali yazilowoozaako nnyo. Wasiba waya, n’okuba switch, n’olinda ettaala ya kiragala. Okumala. Abavuzi b’ennyonyi baali basobola okuddukanya enkola zaabwe nga tebayokya mafuta ga nnyonyi ku ttaka.

Ekitundu ky’amasannyalaze ku ttaka kikola ekyo kyennyini erinnya bwe ligamba. Ewa ennyonyi amaanyi g’amasannyalaze nga yingini zizikiddwa. Endowooza ennyangu. Si kutta kwangu nnyo.

Ekizibu kya 400 Hz

Wano waliwo ekintu abantu abasinga ebweru w’omulimu guno kye batamanyi. Ennyonyi tezikozesa masannyalaze ge gamu n’ennyumba yo. Omukutu gwo ogwa wall outlet gukuwa volts 120 ku 60 Hz. Eyo frequency-60 cycles buli second-ekola bulungi ku firiigi ne air conditioners. Naye kifuula mmotoka z’amasannyalaze okuzitowa.

Obuzito bukutta mu nnyonyi. Buli pawundi gy’okekkereza ku buzito bwa mmotoka, pawundi gy’osobola okujjuza ng’osasula abasaabaze oba emigugu. Kale bayinginiya b’ennyonyi baagenda ne 400 Hz emabega mu myaka gya 1950. Ku frequency eyo, motors ne transformers bikendeera nnyo. Mota ya 400 Hz eyinza okuzitowa kitundu kya motor ya 60 Hz gy’ezitowa olw’amaanyi ge gamu agafuluma.

Okusuubulagana kwe kufiirwa mu kutambuza. Frequency eya waggulu kitegeeza nti amasoboza mangi gavaamu omusaayi mu bbanga. Naye munda mu nnyonyi, amabanga gaba matono. Okukekkereza obuzito okusinga okuliyirira.

Kino kireeta okulumwa omutwe ku ttaka. Tosobola kumala gadduka extension cord okuva ku kizimbe kya terminal. Omukutu gw’ekisaawe ky’ennyonyi gutambulira ku sipiidi ya 50 oba 60 Hz nga buli wamu. Ekintu kirina okukyusa amaanyi ago aga utility okudda ku 400 Hz.

Ekyo ekintu ye GPU.

Ekituufu Ekibeerawo Munda

Enkyusa ennyangu: GPU etwala ensibuko yonna ey’amaanyi gy’erina-yingini ya dizero, amasannyalaze agakozesebwa, bbaatule-era efulumya AC ya 115 volts ku 400 Hz. Oba 28 volts DC ku nnyonyi entono. Ekifuluma kiyita mu waya y’amasavu okutuuka mu kifo ekiriraanye ennyindo y’ennyonyi.

Enkyusa enzibu erimu ebikyusa frequency, voltage regulators, protection circuits, n’ebintu nga lukumi ebiyinza okutambula obubi ku ssaawa 2 ez’oku makya ng’ennyonyi elwawo nga buli omu akuba enduulu.

Ndabye solid-state units okuva mu ITW GSE nga zidduka flawlessly okumala emyaka munaana nga tewali kirala okuggyako enkyukakyuka mu filter. Nze era ndabye ne dizero empya ddala nga zikwata omuliro kubanga waliwo eyeerabira okukebera coolant. Ebikozesebwa birungi nnyo ng’abantu ababiddaabiriza.

Mobile Versus Ebitereezeddwa

Ebisaawe by’ennyonyi ebisinga biddukanya byombi nga bitabuddwamu.

Yuniti ezitakyukakyuka zituula ku kikomera. Basika amasannyalaze okuva ku mudumu gw’amasannyalaze ku kisaawe ne bagakyusa. Cable etuuka ku nnyonyi ng’eyita mu kinnya ekifuluma-up mu seminti oba hose reel essiddwa okumpi awo. Tewali mukka gwa dizero. Tewali ssente za mafuta. Tewali kulumwa mutwe mu nteekateeka. Naye ggwe weewaddeyo. Yuniti eyo bw’emenya, oba osikambula okunoonya ‘mobile backup’ ng’abasaabaze balaba mu ddirisa.

Mobile units zitambulira ku bigaali ebiriko emipiira. Abakozi ku ttaka bazisikambula ne tulakita. Emirimu gy’amasomero amakadde buli kimu gyakiddukanya bwe kiti. Okukyukakyuka kw’ebintu kwa ddala. Ennyonyi zisimba ku siteegi ey’ewala nga tewali masannyalaze gatakyukakyuka? Yiringisiza mobile unit eyo. Okuddukanya emigugu ku ludda olw’ewala olw’ennimiro? Ddiiru y’emu.

Ebibi nabyo bya ddala. Oyokya dizero okusika ebintu bino okudda n’okudda. Ebidduka ebingi ku kkubo kitegeeza emikisa mingi egy’obubenje. Era omuntu alina okukwasaganya unit ki egenda wa. Ekyo kiwulikika nga ekitaliimu nsa okutuusa lw’ofuna ennyonyi 200 olunaku ne yuniti ssatu wansi okuddaabiriza.

Yuniti eziteekeddwa ku bridge-ziwanikiddwa wansi w'omutala gwa jet. Zitambula n’omutala, kale bulijjo waya ebeera kumpi n’ekifo ennyonyi we zikwata. Okugonjoola ensonga mu ngeri ey’amagezi. Naye bamakanika babakyawa kubanga tosobola kukola service ya unit ng’ennyonyi eri ku ggeeti. Gezaako okunnyonnyola supavayiza wo nti olina okuggya omutala mu nkola mu kiseera ky’okusika emisana.

Enkyukakyuka ya Battery

Emyaka kkumi egiyise, GPU ezikozesa bbaatule-zaali za kwegomba. Lead-acid packs zaali nzito nnyo era nga teziwangaala. Wandifunye mpozzi ennyonyi ssatu oba nnya okukyuka nga tonnaba kwetaaga kuddamu kucaajinga.

Lithium iron phosphate yakyusa ekyo.

Yuniti za bbaatule empya zisobola okukwata enkyukakyuka kkumi oba kkumi na bbiri enfunda-body turns ku charge emu. Zizitowa wansi wa kitundu ky’ebyo ebiringa eby’omusulo-asidi bye bizitowa. Era basirise. Ntegeeza genuinely quiet. Tewali kuwuuma kwa dizero. Tewali mukka gufuluma. Abakozi b’oku ttaka baakirabye mangu.

Japan Airlines yatandika okukola GPU za bbaatule za lithium ku kisaawe ky’ennyonyi e Matsuyama omwaka oguwedde. Ensonga ze baategeeza zaali za kukendeeza ku bucaafu obufuluma mu bbanga n’amaloboozi. Naye nteebereza nti ddereeva omutuufu yali ssente za ndabirira. Yingini za dizero zeetaaga okukyusa woyiro, okukyusa ffilta, okuyonja empiso. Battery packs kumpi tezeetaaga kintu kyonna.

Kkampuni ya AERO Specialties etunda yuniti erimu obutoffaali bwa lithium iron phosphate obutaliimu cobalt. Ekyo kikulu kubanga enjegere z’okugabira kobalt kavuyo-mu mpisa n’enteekateeka. Battery era zikyuka ne zidda mu byuma ebirala eby'oku ttaka nga tezikyasobola kukwata mulimu gwa GPU ogwetaagisa ennyo-. Ekyokubiri-enkozesa y'obulamu. Okulabika obulungi.

Start Pac ebadde ku kino okuva mu 1997. Jim Wurth omu ku baatandikawo ennyonyi eno yali muvuzi wa nnyonyi ya Eastern Airlines eyabuuka nnamunkanga oluvannyuma lw’okuwummula. Emboozi egamba nti yasibira awalala remote nga battery ye eya MD500 tegenda kukola crank mu budde obw’ennyogovu. Yakola yinginiya w’ekitongole kye eky’okutandika. Mukyala we Judith yalaba omukisa gwa bizinensi. Nga wayise emyaka 20{6}}etaano basindise yuniti ezisoba mu 50,000.

Yuniti zaabwe eza lithium ezitambuzibwa zizitowa pawundi kkumi. Kkumi. Osobola okusuula emu mu kisenge omuteekebwa emigugu nga yinsuwa. Abavuzi b’ennyonyi abagenda mu bisaawe by’ennyonyi bye batamanyi babaagala nnyo.

Ensonga z’okupima obunene

Ennyonyi ya Boeing 737 oba Airbus A320 yeetaaga omukutu gumu ogwa kVA 90. Ennyonyi ya Boeing 777 yeetaaga bbiri. Ekibya ku mubiri omufunda-kituula mita nga bbiri okuva ku ttaka. Emibiri emigazi-gigiteeka okumpi ne mita ssatu, kale weetaaga amadaala.

Okukendeeza ku sayizi kya bulabe. Okusasula ekisusse ku busobozi bw’oteetaaga kuba kwonoona kwokka.

Nze ndabye abaddukanya emirimu nga bagula yuniti esinga obunene eriwo kuba baalowooza nti ejja kubikka buli kimu. Olwo ne beemulugunya ku nkozesa y’amafuta oba ebiseera by’okucaajinga. Oyagala ekintu ekituufu, so si kikozesebwa ekisinga obunene.

Puleesa y’obutonde bw’ensi

Ekisaawe ky’ennyonyi e Zurich kyafulumya ebikwata ku kisaawe emyaka mitono emabega nga kigeraageranya omukka ogufuluma mu yuniti z’amasannyalaze agayamba ennyonyi okusinziira ku masannyalaze ag’oku ttaka. APU ekola CO2 esingako emirundi nga kkumi buli ssaawa. Emirundi kkumi.

Etteeka ly’omukago gwa Bulaaya erikwata ku bbaatule liyingiddewo liragira abakola bbaatule okulangirira ebigere bya kaboni ebifulumizibwa. Ekyo kigenda kunyigiriza okusalawo ku kugula ebintu. Ennyonyi n’ebisaawe by’ennyonyi okulondoola scope 3 emissions zeetaaga data eno.

Diesel GPUs tezigenda nkya. Naye obulagirizi butegeerekeka bulungi. Buli kkampuni enkulu ekola ebintu egenda egaziya layini zaabwe ez’amasannyalaze ne bbaatule. ITW GSE, TLD, AERO Ebikugu-byonna.

Bye Ntegeeza Abaguzi

Sooka omanye ebyetaago byo ebituufu. Emiryango emeka? Bika ki eby’ennyonyi? Enkyukakyuka mmeka buli lunaku? Ebintu byo eby'amasannyalaze bifaanana bitya?

Fixed solid-state units zikola amakulu ku miryango gy'ebidduka egy'amaanyi-nga girina amaanyi amalungi ag'omugaso. Battery units zikola bulungi ku remote stands oba operations nga tosobola kuddukanya masannyalaze infrastructure mu ngeri ennyangu. Dizero ekyalina ekifo ky’amasannyalaze aga ‘backup power’ oba ebifo ebirimu emikutu egiteesigika.

Togula okusinziira ku spec sheet yokka. Yogerako n’abaddukanya emirimu abaddukanya ebyuma bye bimu. Buuza ku ngeri y’okulemererwa n’okubeerawo kw’ebitundu. Yuniti ekola obulungi mu kifo ekigezesa omukozi eyinza okulwana mu bbugumu ly’omusana mu Phoenix oba mu mbeera ey’obutiti mu Minneapolis.

Ne mbalirira y’okutendekebwa. Nze ndabye ebyuma eby’ebbeeyi nga byonoonese kubanga tewali yayigiriza ba ramp agents engeri y’okuyunga obulungi cable. LED ya interlock eriwo olw’ensonga.
