Ngesikhathi sokulungiselela ukwakhiwa kwe-iziteshi zokushaja ze-eV zezentengiselwano, umbuzo wokuqala noyinhloko abangane abaningi abahlangana nawo uthi: “Kufanele ngibe ne-transformer enkulu kangakanani?” Lo mbuzo ubalulekile ngoba ama-transformer ebhokisi afana “nenhliziyo” yayo yonke inqwaba yokushaja, aguqula ugesi onamandla aphezulu ube ugesi onamandla aphansi otholakalayo.izinqwaba zokushaja izimoto zikagesi, futhi ukukhethwa kwayo kuhlobene ngqo nokusebenza kahle kokusebenza, izindleko zokuqala kanye nokukhula kwesikhathi esizayo kwesiteshi sokushaja se-ev.
1. Isimiso esiyisisekelo: ukufanisa amandla yisisekelo
Isinyathelo sokuqala ekukhetheni i-transformer ukwenza ukufaniswa kwamandla okunembile. I-logic eyisisekelo ilula kakhulu:
Bala inani elipheleleisiteshi sokushaja izimoto zikagesiamandla: Engeza amandla azo zonke iziteshi zokushaja ohlela ukuzifaka.
Umthamo we-transformer ohambisanayo: Umthamo we-transformer (iyunithi: kVA) kufanele ube mkhulu kancane kunamandla aphelele e-isiteshi sokushaja se-ev(iyunithi: kW) ukushiya umkhawulo othile kanye nesikhala se-buffer sesistimu.
2. Amacala asebenzayo: izindlela zokubala ezingaqondakala ngokushesha
Ake sisebenzise izimo ezimbili ezijwayelekile ukuze sikubale:
Ikesi 1: Yakha ama-pile okushaja okusheshayo angu-5 angu-120kW DC
Ukubalwa kwamandla aphelele: amayunithi ama-5 × 120kW/iyunithi = 600kW
Ukukhetha i-transformer: Okwamanje, ukukhetha i-transformer yebhokisi engu-630kVA kuyindlela efaneleke kakhulu futhi evamile. Ingathwala kahle umthwalo ophelele ongu-600kW ngenkathi ishiya isilinganiso esifanele ukuqinisekisa ukusebenza okuzinzile nokuphumelelayo kwemishini.
Icala 2: Yakha 10Izinqwaba zokushaja okusheshayo ze-DC ezingu-120kW
Ukubalwa kwamandla aphelele: amayunithi ayi-10 × 120kW/iyunithi = 1200kW
Ukukhethwa kwe-Transformer: Ukuze uthole amandla aphelele angu-1200kW, ukukhetha kwakho okungcono kakhulu i-transformer yebhokisi engu-1250kVA. Le ncazelo yenzelwe leli zinga lamandla, iqinisekisa ukunikezwa kwamandla okwanele nokuthembekile.
Ngezibonelo ezingenhla, uzothola ukuthi ukukhethwa kwama-transformer akugcini nje ngokucatshangwa, kodwa kune-logic ecacile yezibalo okufanele ilandelwe.
3. Ukucabanga okuthuthukile: gcina isikhala sentuthuko yesikhathi esizayo
Ukuba nokuhlela okubheke phambili ekuqaleni kwephrojekthi kuyisibonakaliso sobuhlakani bebhizinisi. Uma ubona ukuthi kungenzeka ukuthi kwandiswe iphrojekthi esikhathini esizayo.isiteshi sokushaja imoto kagesi, kufanele ucabangele ukuyinika “amandla” aqinile lapho ukhetha “inhliziyo” esinyathelweni sokuqala.
Isu elithuthukisiwe: Thuthukisa umthamo we-transformer ngenothi elilodwa njengoba isabelomali sivuma.
Uma kwenzeka ama-piles ama-5, uma unganelisekile nge-630kVA, ungacabanga ngokuthuthukela ku-transformer engu-800kVA.
Ngesitsha esinezinqwaba eziyi-10, kungacatshangwa nge-transformer enamandla kakhulu engu-1600kVA.
Izinzuzo zalokhu zisobala: uma udinga ukwandisa inaniizinqwaba zokushaja izimoto zikagesiesikhathini esizayo, asikho isidingo sokushintsha i-transformer, okuyimishini eyinhloko nebiza kakhulu, futhi kudingeka ukunwetshwa komugqa okulula kuphela, okusindisa kakhulu izindleko nesikhathi sokutshalwa kwezimali kwesibili, okuvumelaisiteshi sokushaja izimoto ze-evukuba nokukhula okunamandla.
Ekuphetheni, ukukhetha i-transformer efanele ye-ishaja ye-evkuyinqubo yokwenza izinqumo elinganisela “izidingo zamanje” “nentuthuko yesikhathi esizayo”. Ukubalwa kwamandla okunemba kubalulekile ekuqinisekiseni ukuzinza kwemisebenzi yamanje, kuyilapho ukuhlela okubheke phambili okulinganiselwe kuyisivikelo esibalulekile sokukhula okuqhubekayo kwe-ROI.
Uma uhlelaisiteshi sokushajaiphrojekthi futhi usenemibuzo mayelana nokukhetha i-transformer, sicela ukhululeke ukuxhumana nathi. Sizimisele ukusebenzisa ulwazi lwethu lobuchwepheshe lobuchwepheshe ukukunikeza ukubonisana kwezixazululo ezenziwe ngokwezifiso mahhala ukukusiza wakhe isiteshi sokushaja esisebenzayo esinamandla okukhula!
