Kwinkqubo yokulungiselela ulwakhiwo lwe-aizikhululo zokutshaja ev, umbuzo wokuqala kunye nongundoqo odibana nabahlobo abaninzi: "Ndimele ndibe ne-transformer enkulu kangakanani?" Lo mbuzo ubalulekile kuba iziguquli zebhokisi zifana “nentliziyo” yayo yonke imfumba yokutshaja, iguqula umbane onamandla ombane omkhulu ube ngumbane one-voltage ephantsi ekhoyo.iimfumba zokutshaja iimoto zombane, kunye nokukhethwa kwayo kuhambelana ngokuthe ngqo nokusebenza kakuhle, iindleko zokuqala kunye nokulinganisa kwexesha elizayo lesikhululo sokutshaja i-ev.
1. Umgaqo osisiseko: ukuhambelana kwamandla ngundoqo
Inyathelo lokuqala ekukhetheni i-transformer kukwenza umdlalo ochanekileyo wamandla. Ingqiqo esisiseko ilula kakhulu:
Bala itotaliisikhululo sokutshaja isithuthi sombaneamandla: Dibanisa amandla azo zonke izikhululo zokutshaja oceba ukuzifaka.
Umthamo wesiguquli esihambelanayo: Umthamo wesiguquli (iyunithi: kVA) kufuneka ube mkhulu kancinane kunamandla ewonkeisikhululo sokutshaja ev(iyunithi: kW) ukushiya umda othile kunye nesithuba se-buffer kwinkqubo.
2. Iimeko ezisebenzayo: iindlela zokubala ezinokuqondwa ngokukrwaqula
Masisebenzise iimeko ezimbini eziqhelekileyo ukubalela wena:
Imeko 1: Yakha i-5 120kW DC iimfumba zokutshaja ngokukhawuleza
Iyonke indlela yokubala amandla: iiyunithi ezi-5 × 120kW/iyunithi = 600kW
Ukukhetha umguquli: Ngeli xesha, ukukhetha i-630kVA ibhokisi ye-transformer yeyona nto ifanelekileyo kwaye iqhelekileyo. Iyakwazi ukuthwala ngokupheleleyo umthwalo opheleleyo we-600kW ngelixa ishiya umda ofanelekileyo ukuqinisekisa ukusebenza okuzinzileyo nokusebenzayo kwezixhobo.
Ityala lesi-2: Yakha i-10I-120kW DC iimfumba zokutshaja ngokukhawuleza
Iyonke indlela yokubala amandla: iiyunithi ezili-10 × 120kW/iyunithi = 1200kW
UKhetho lweTransformer: Ngamandla ewonke ayi-1200kW, eyona ndlela onokukhetha kuyo yi-1250kVA yebhokisi yokutshintsha. Le nkcazelo ilungiselelwe lo mgangatho wamandla, iqinisekisa unikezelo lwamandla olwaneleyo noluthembekileyo.
Ngokusebenzisa le mizekelo ingasentla, uya kufumanisa ukuba ukukhethwa kwabaguquli akucingelwanga nje, kodwa kunengqiqo ecacileyo yeemathematika.
3. Ukucinga okuphezulu: gcina indawo yophuhliso lwexesha elizayo
Ukuba nesicwangciso esijonge phambili ekuqaleni kweprojekthi luphawu lweshishini acumen. Ukuba ubona kwangaphambili ukuba kunokwenzeka ukwandiswa kwexesha elizayo leisikhululo sokutshaja iimoto zombane, kufuneka ucinge ukunika "amandla" anamandla xa ukhetha "intliziyo" kwisinyathelo sokuqala.
Isicwangciso esiphezulu: Ukuphucula umthamo we-transformer ngenotshi enye njengoko uhlahlo lwabiwo-mali luvumela.
Kwimeko yeemfumba ezi-5, ukuba awonelisekanga yi-630kVA, ungacinga ngokunyusela kwi-800kVA transformer.
Kwimeko ye-10-pile, i-transformer enamandla ngakumbi ye-1600kVA inokuqwalaselwa.
Izibonelelo zale nto zicacile: xa ufuna ukwandisa inani leiimfumba zokutshaja iimoto zombanekwixesha elizayo, akukho mfuneko yokutshintsha i-transformer, eyona nto ingundoqo kunye nezixhobo ezibizayo, kwaye ulwandiso lomgca olulula kuphela olufunekayo, olugcina kakhulu iindleko kunye nexesha lotyalo-mali lwesibini, ukuvumelaisikhululo sokutshaja iimoto evukuba nokukhula olomeleleyo.
Ukuqukumbela, ukukhetha i-transformer efanelekileyo kwi-aev itshajayinkqubo yokwenza izigqibo ezilinganisa "iimfuno zangoku" kunye "nophuhliso lwexesha elizayo". Ubalo oluchanekileyo lwamandla luyisiseko ekuqinisekiseni ukuzinza kwemisebenzi yangoku, ngelixa ukucwangciswa okujonge phambili okuphakathi kuyi-inshurensi ebalulekileyo yokukhula okuqhubekayo kwe-ROI.
Ukuba uceba aisiskhululo sokugcwalisaIprojekthi kwaye usenemibuzo malunga nokukhethwa kwe-transformer, nceda uzive ukhululekile ukuqhagamshelana nathi. Sizimisele ukusebenzisa amava ethu obugcisa obuchwephesha ukuze sikubonelele ngesisombululo esilungiselelweyo sasimahla ukukunceda ukuba wakhe isikhululo sokutshaja esisebenzayo esinokukhula!
