Ngesikhathi kulungiselelwa ukwakhiwa kwe-aiziteshi zokushaja ze-ev, umbuzo wokuqala nobalulekile abangani abaningi ababhekana nawo uthi: “Kufanele ngibe ne-transformer enkulu kangakanani?” Lo mbuzo ubalulekile ngoba iziguquli zamabhokisi zifana “nenhliziyo” yayo yonke inqwaba eshajayo, eziguqula ugesi onamandla kagesi ube ugesi ongamandla kagesi aphansi otholakalayo.inqwaba yokushaja imoto kagesi, futhi ukukhethwa kwayo kuhlobene ngokuqondile nokusebenza kahle, izindleko zokuqala kanye nokulinganisa okuzayo kwesiteshi sokushaja i-ev.
1. Isimiso esiyisisekelo: ukufanisa amandla kuwumongo
Isinyathelo sokuqala ekukhetheni i-transformer ukwenza ukufanisa amandla okunembile. I-logic eyisisekelo ilula kakhulu:
Bala inaniisiteshi sokushaja imoto kagesiamandla: Hlanganisa amandla azo zonke iziteshi zokushaja ohlela ukuzifaka.
Umthamo we-transformer ehambelanayo: Umthamo we-transformer (iyunithi: kVA) kufanele ibe mkhulu kancane kunamandla apheleleisiteshi sokushaja se-ev(iyunithi: kW) ukuze ushiye imajini ethile nesikhala sebhafa sesistimu.
2. Amacala angokoqobo: izindlela zokubala ezingaqondwa ngokuphazima kweso
Masisebenzise izimo ezimbili ezijwayelekile ukuze sikubalele:
Ikesi 1: Yakha izinqwaba zokushaja ezisheshayo ezingu-5 120kW DC
Isamba sokubala kwamandla: amayunithi ama-5 × 120kW/iyunithi = 600kW
Ukukhetha i-Transformer: Ngalesi sikhathi, ukukhetha isiguquli sebhokisi esingu-630kVA kuyisinqumo esifanelekile nesivamile. Ingakwazi ukuthwala ngokugcwele amandla angu-600kW kuyilapho ishiya umkhawulo ofanele ukuze kuqinisekiswe ukusebenza okuzinzile nokusebenza kahle kwemishini.
Icala lesi-2: Yakha i-10120kW DC inqwaba yokushaja okusheshayo
Isamba sokubala kwamandla: amayunithi ayi-10 × 120kW/iyunithi = 1200kW
Ukukhetha I-Transformer: Ukuze uthole amandla angu-1200kW esewonke, ukukhetha kwakho okuhle yi-1250kVA box transformer. Lokhu kucaciswa kwenzelwe leli zinga lamandla, kuqinisekisa ukutholakala kwamandla anele futhi okuthembekile.
Ngezibonelo ezingenhla, uzothola ukuthi ukukhethwa kwama-transformer akucatshangwa nje, kodwa kunomqondo ocacile wezibalo okufanele ulandelwe.
3. Ukucabanga okuthuthukile: gcina indawo yentuthuko yesikhathi esizayo
Ukuba nokuhlela okubheke phambili ekuqaleni kwephrojekthi kuwuphawu lwebhizinisi acumen. Uma ubona kusengaphambili ukuthi kungenzeka ukunwetshwa esikhathini esizayoisiteshi sokushaja imoto kagesi, kufanele ucabange ukuyinika “amandla” anamandla lapho ukhetha “inhliziyo” esinyathelweni sokuqala.
Isu elithuthukile: Thuthukisa umthamo wesiguquli ngenotshi eyodwa njengoba ibhajethi ivuma.
Odabeni lwama-piles angu-5, uma unganelisekile ngo-630kVA, ungacabangela ukuthuthukela ku-800kVA transformer.
Ngekesi lenqwaba eyi-10, i-transformer enamandla ka-1600kVA ingacatshangelwa.
Izinzuzo zalokhu zisobala: lapho udinga ukwandisa inani leinqwaba yokushaja imoto kagesiesikhathini esizayo, asikho isidingo sokuthatha indawo ye-transformer, okuyimishini ewumgogodla nebizayo, futhi kudingeka ukunwetshwa komugqa okulula kuphela, okusindisa kakhulu izindleko nesikhathi sokutshalwa kwezimali kwesibili, okuvumelaisiteshi sokushaja izimoto evukuba nokukhula okuqinile.
Sengiphetha, ukukhetha i-transformer efanele aev ishajaiwuhlelo lokuthatha izinqumo olulinganisa “izidingo zamanje” “nentuthuko yesikhathi esizayo”. Izibalo zamandla ezinembile zibalulekile ekuqinisekiseni ukuzinza kwemisebenzi yamanje, kuyilapho ukuhlela okulingene ukubheka phambili kuwumshuwalense obalulekile wokuqhubeka nokukhula kwe-ROI.
Uma uhlela aisiteshi sokushajaiphrojekthi futhi usenemibuzo mayelana nokukhethwa kwe-transformer, sicela ukhululeke ukuxhumana nathi. Sizimisele ukusebenzisa ulwazi lwethu lobuchwepheshe ukuze sikunikeze ukubonisana kwamahhala kwesixazululo esingokwezifiso ukuze sikusize wakhe isiteshi sokushaja esisebenza kahle esinamandla okukhula!
