Kwinkqubo yokulungiselela ukwakhiwa kweizikhululo zokutshaja ii-ev zorhwebo, umbuzo wokuqala noyintloko abahlobo abaninzi abadibana nawo ngulo: “Ndifanele ndibe ne-transformer enkulu kangakanani?” Lo mbuzo ubalulekile kuba ii-box transformers zifana “nentliziyo” yayo yonke inqwaba yokutshaja, ziguqula umbane osebenza ngamandla aphezulu ube ngumbane osebenza ngamandla aphantsi ofumanekayo.iinqwaba zokutshaja iimoto zombane, kwaye ukhetho lwayo lunxulumene ngokuthe ngqo nokusebenza kakuhle, iindleko zokuqala kunye nokukhula kwexesha elizayo kwesikhululo sokutshaja se-ev.
1. Umgaqo osisiseko: ukuthelekisa amandla ngundoqo
Inyathelo lokuqala ekukhetheni i-transformer kukwenza uthelekiso lwamandla oluchanekileyo. Ingqiqo esisiseko ilula kakhulu:
Bala itotaliisikhululo sokutshaja izithuthi zombaneamandla: Yongeza amandla azo zonke izitishi zokutshaja oceba ukuzifaka.
Umthamo wetransformer ohambelanayo: Umthamo wetransformer (iyunithi: kVA) kufuneka ube mkhulu kancinci kunamandla ewonke e-isikhululo sokutshaja se-ev(iyunithi: kW) ukushiya umda othile kunye nendawo ye-buffer yenkqubo.
2. Amatyala asebenzayo: iindlela zokubala ezinokuqondwa ngokukhawuleza
Masisebenzise iimeko ezimbini eziqhelekileyo ukuze sikubale:
Ityala 1: Yakha iipali zokutshaja ezikhawulezayo ze-5 120kW DC
Ukubalwa kwamandla apheleleyo: iiyunithi ezi-5 × 120kW/iyunithi = 600kW
Ukukhetha i-transformer: Okwangoku, ukukhetha i-transformer yebhokisi ye-630kVA lolona khetho lufanelekileyo noluqhelekileyo. Ingathwala umthwalo opheleleyo we-600kW ngelixa ishiya umda ofanelekileyo ukuqinisekisa ukusebenza okuzinzileyo nokufanelekileyo kwezixhobo.
Ityala lesi-2: Yakha i-10Iipali zokutshaja ezikhawulezayo ze-120kW DC
Ukubalwa kwamandla apheleleyo: iiyunithi ezili-10 × 120kW/iyunithi = 1200kW
Ukukhetha iTransformer: Ukuze ufumane amandla apheleleyo e-1200kW, ukhetho lwakho olungcono yitransformer yebhokisi ye-1250kVA. Olu lwazi lulungiselelwe eli nqanaba lamandla, luqinisekisa ukunikezelwa kwamandla okwaneleyo nokuthembekileyo.
Ngemizekelo engentla, uya kufumanisa ukuba ukukhethwa kwee-transformers akupheleli nje ekucingelweni, kodwa kunengqiqo ecacileyo yezibalo ekufuneka ilandelwe.
3. Ukucinga okuphucukileyo: gcina indawo yophuhliso lwexesha elizayo
Ukuba nocwangciso olujonge phambili ekuqaleni kweprojekthi luphawu lobuchule boshishino. Ukuba ubona kwangaphambili ukuba kunokwenzeka ukuba kwandiswe iprojekthi kwixesha elizayoisikhululo sokutshaja iimoto zombane, kufuneka ucinge ngokuyinika “amandla” aqinileyo xa ukhetha “intliziyo” kwinyathelo lokuqala.
Icebo eliphambili: Phucula umthamo wetransformer ngenotshi enye njengoko uhlahlo lwabiwo-mali luvuma.
Kwimeko yeepali ezi-5, ukuba awonelisekanga yi-630kVA, ungacinga ngokuyiphucula uye kwi-transformer ye-800kVA.
Kwityala elineepali ezili-10, i-transformer enamandla ngakumbi ye-1600kVA ingaqwalaselwa.
Iingenelo zoku zicacile: xa kufuneka unyuse inaniiinqwaba zokutshaja iimoto zombanekwixesha elizayo, akukho mfuneko yokutshintsha i-transformer, eyisixhobo esiphambili nesibizayo, kwaye kufuneka ulwandiso lomgca olulula kuphela, olugcina kakhulu iindleko kunye nexesha lotyalo-mali lwesibini, okuvumela ukubaisikhululo sokutshaja iimoto ze-evukuba nokukhula okunamandla.
Ukuqukumbela, ukukhetha i-transformer efanelekileyoitshaja ye-evyinkqubo yokwenza izigqibo elinganisela “iimfuno zangoku” kunye “nophuhliso lwexesha elizayo”. Ukubalwa kwamandla ngokuchanekileyo kubalulekile ekuqinisekiseni uzinzo lwemisebenzi yangoku, ngelixa ucwangciso olujonge phambili oluphakathi luyinshurensi ebalulekileyo yokukhula kwe-ROI okuqhubekayo.
Ukuba ucebaisiskhululo sokugcwalisaiprojekthi kwaye usenemibuzo malunga nokukhetha i-transformer, nceda uzive ukhululekile ukunxibelelana nathi. Sizimisele ukusebenzisa amava ethu obuchwephesha obuchwephesha ukukunika iingcebiso zesisombululo ezenzelwe wena simahla ukukunceda wakhe isikhululo sokutshaja esisebenzayo esinokukhula!
