Ngophuhliso olukhulayo lweshishini elitsha lezithuthi zamandla, i-DC yokutshaja imfumba, njengeyona ndawo iphambili yokutshaja iimoto zombane ngokukhawuleza, ngokuthe ngcembe ikwindawo ebalulekileyo kwintengiso, kwaye.BeiHai Amandla(I-China), njengelungu lentsimi yamandla amatsha, nayo yenza igalelo elibalulekileyo ekuthandeni nasekukhuthazeni amandla amatsha. Kweli nqaku, siza kuchaza ngokubanzi iimfumba zokutshaja ze-DC ngokwetekhnoloji yesicelo, umgaqo wokusebenza, amandla okutshaja, ubume bokuhlelwa, iimeko zokusetyenziswa kunye neempawu.
Ukusetyenziswa kweteknoloji
I-DC yokutshaja imfumba (ebizwa ngokuba yi-DC yokutshaja imfumba) ithatha itekhnoloji ye-elektroniki yamandla aphambili, kwaye undoqo wayo ilele kwi-inverter yangaphakathi. Ingundoqo ye-inverter yi-inverter yangaphakathi, enokuthi iguqule ngokufanelekileyo amandla e-AC ukusuka kwigridi yamandla ukuya kumandla e-DC kwaye inikezele ngokuthe ngqo kwibhetri yesithuthi sombane sokutshaja. Le nkqubo yokuguqulwa yenziwa ngaphakathi kwendawo yokutshaja, ukuphepha ukulahlekelwa kwamandla okuguqulwa kwe-EV kwi-inverter yebhodi, ephucula kakhulu ukusebenza kakuhle kokutshaja. Ukongezelela, isithuba sokutshaja kwe-DC sixhotyiswe ngenkqubo yokulawula ehlakaniphile elungelelanisa ngokuzenzekelayo ukutshaja kwangoku kunye ne-voltage ngokwexesha langempela lebhetri, iqinisekisa inkqubo yokutshaja ekhuselekileyo nesebenzayo.
UmGaqo wokuSebenza
Umgaqo osebenzayo we-DC yokutshaja imfumba ikakhulu ibandakanya imiba emithathu: uguqulo lwamandla, ulawulo lwangoku kunye nolawulo lonxibelelwano:
Uguqulo lwamandla:I-DC yokutshaja imfumba kufuneka kuqala iguqule amandla e-AC kumandla e-DC, aphunyezwa ngumlungisi wangaphakathi. Umlungisi udla ngokuthatha isekethe yokuhlaziya ibhulorho, eyenziwe ngeediode ezine, kwaye inokuguqula iziqingatha ezingalunganga nezilungileyo zamandla e-AC zibe amandla eDC ngokulandelelanayo.
Ulawulo lwangoku:Iitshaja zeDC kufuneka zilawule umsinga wokutshaja ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwenkqubo yokutshaja. Ulawulo lwangoku lufezekiswa ngumlawuli otshajayo ngaphakathi kwemfumba yokutshaja, enokuthi iguqule ngokuguquguqukayo ubungakanani bomjelo wokutshaja ngokwemfuno yesithuthi sombane kunye nomthamo wemfumba yokutshaja.
Ulawulo lonxibelelwano:Iimfumba zokutshaja ze-DC zihlala zinomsebenzi wokunxibelelana nesithuthi sombane ukuqonda ulawulo kunye nokubeka iliso kwinkqubo yokutshaja. Ulawulo lwezonxibelelwano lufezekiswa ngemodyuli yonxibelelwano ngaphakathi kwinqwaba yokutshaja, enokuthi iqhube unxibelelwano lweendlela ezimbini kunye nesithuthi sombane, kubandakanywa ukuthumela imiyalelo yokuhlawula ukusuka kwintlambo yokuhlawula kwisithuthi sombane kunye nokufumana ulwazi lobume besithuthi sombane.
Amandla okutshaja
Iimfumba zokutshaja ze-DC zaziwa ngamandla azo aphezulu wokutshaja. Kukho iintlobo ngeentloboItshaja zeDCemarikeni, kuquka 40kW, 60kW, 120kW, 160kW nkqu 240kW. Ezi tshaja ezinamandla eziphezulu ziyakwazi ukukhawuleza ukuzalisa izithuthi zombane ngexesha elifutshane, ukunciphisa kakhulu ixesha lokutshaja. Umzekelo, indawo yokutshaja i-DC enamandla ali-100kW inakho, phantsi kweemeko ezifanelekileyo, ukutshaja ibhetri yesithuthi sombane ukuze iphelele kwisithuba esimalunga nesiqingatha seyure ukuya kwiyure. Itekhnoloji yokutshaja kakhulu ide yonyuse amandla okutshaja aye ngaphezulu kwe-200kW, icuthe ngakumbi ixesha lokutshaja kwaye izisa uncedo olukhulu kubasebenzisi bezithuthi zombane.
Ukuhlelwa kunye noKwakha
Iimfumba zokutshaja ze-DC zinokuhlelwa ukusuka kwimilinganiselo eyahlukeneyo, njengobungakanani bamandla, inani lemipu yokutshaja, ifom yesakhiwo kunye nendlela yokufaka.
Ubume bemfumba yokutshaja:Iimfumba zokutshaja ze-DC zinokuhlelwa zibe yimfumba edityanisiweyo yokutshaja ye-DC kwaye yahlule imfumba yokutshaja ye-DC.
Imigangatho yoncedo lokutshaja:inokwahlulwa ngokwemigangatho yaseTshayina:GB/T; Umgangatho waseYurophu: I-IEC (I-International Electrotechnical Commission); Umgangatho wase-US: i-SAE (uMbutho weeNjineli zeeMoto zase-United States); Umgangatho waseJapan: CHAdeMO (eJapan).
Uluhlu lokutshaja imipu:ngokwenani lemipu yetshaja yemfumba yokutshaja inokwahlulwa ibe ngumpu omnye, imipu ephindwe kabini, imipu emithathu, kwaye inokwenziwa ngokwezifiso ngokwemfuno yokwenyani.
Ulwakhiwo lwangaphakathi lwesithuba sokutshaja:Inxalenye yombane yeIsithuba sokubiza i-DCibandakanya isiphaluka sokuqala kunye nesekethe yesibini. Igalelo lesekethe eliphambili linqanaba lesithathu le-AC amandla, aguqulwa abe yi-DC amandla amkelekileyo kwibhetri ngemodyuli yokutshaja (imodyuli yokuhlaziya) emva kokufaka i-breaker circuit kunye ne-AC smart meter, kwaye emva koko iqhagamshelwe kwi-fuse kunye neshaja umpu ukuhlawula isithuthi sombane. Isekethe yesibini iquka ukutshaja umlawuli wemfumba, umfundi wekhadi, isikrini sokubonisa, imitha ye-DC, njl.
Ukusetyenziswa kwemeko
DC ukutshaja iimfumbazisetyenziswa kakhulu kwiindawo ezahlukeneyo ezifuna ukuzaliswa ngokukhawuleza kombane ngenxa yeempawu zazo zokutshaja ngokukhawuleza. Kwintsimi yezothutho zikawonke-wonke, ezifana neebhasi zedolophu, iiteksi kunye nezinye i-high-frequency, izithuthi ezihamba phambili ezihamba phambili, i-DC yokutshaja inqwaba ibonelela ngesisombululo esithembekileyo sokutshaja ngokukhawuleza. Kwiindawo zeenkonzo zohola wendlela, iindawo ezinkulu zokuthenga, iindawo zokupaka iimoto zikawonke-wonke kunye nezinye iindawo zikawonke-wonke, iimfumba zokutshaja ze-DC nazo zibonelela ngeenkonzo zokutshaja ezifanelekileyo kubasebenzisi bezithuthi zombane ezidlulayo. Ukongeza, iimfumba zokutshaja ze-DC zihlala zifakwa kwiindawo ezikhethekileyo ezinje ngeepaki zemizi-mveliso kunye neepaki zezothutho ukuhlangabezana neemfuno zokuhlawuliswa kwezithuthi ezikhethekileyo epakini. Ngokuduma kwezithuthi zamandla amatsha, iindawo zokuhlala ziye zaqala ngokuthe ngcembe ukufaka iimfumba zokutshaja ze-DC ukubonelela ngokulula ukutshaja kwizithuthi zombane zabahlali.
Iimbonakalo
Ukusebenza okuphezulu kunye nesantya: Ukuguqulwa kwamandla e-DC yokutshaja imfumba kugqitywe ngaphakathi kwemfumba, kuthintelwa ukulahleka kwe-inverter ekwibhodi kunye nokwenza ukutshaja kusebenze ngakumbi. Kwangaxeshanye, amandla aphezulu okutshaja enza ukuba izithuthi zombane zitshajiswe ngokukhawuleza ngexesha elifutshane.
Isebenza ngokubanzi: Iimfumba zokutshaja ze-DC zilungele iimeko ezahlukeneyo zokusetyenziswa, kubandakanywa izithuthi zikawonke-wonke, izikhululo ezikhethekileyo, iindawo zikawonke-wonke kunye neendawo zokuhlala, njl., ukuhlangabezana neemfuno zokutshaja zabasebenzisi abahlukeneyo.
Ihlakaniphile kwaye ikhuselekile: I-DC yokutshaja iimfumba ezixhotywe ngenkqubo yokulawula ehlakaniphile inokubeka iliso kwimeko yebhetri ngexesha langempela kwaye ilungelelanise ngokuzenzekelayo iiparitha zokutshaja ukuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yokutshaja.
Ukukhuthaza ukuphuhliswa kwezithuthi zamandla amatsha: ukusetyenziswa okubanzi kwe-DC yokutshaja imfumba ibonelela ngenkxaso eqinileyo yokuthandwa kwezithuthi zamandla amatsha kunye nokukhuthaza uphuhliso olukhawulezayo lweshishini lezithuthi zamandla amatsha.
