Isikhokelo Sokugqibela Sokufakela Izikhululo ze-DC Ezixhonywe Eludongeni ze-MIDA: Ucwangciso Lwendawo Olucwangcisiweyo Lokusetyenziswa Kwendawo Eninzi

Intshayelelo: Ukubaluleka koFakelo loBugcisa

Njengoko ukwamkelwa kwezithuthi zombane (ii-EV) kukhawulezisa, amashishini ukusuka kwiihotele ukuya kubaqhubi beenqwelo-mafutha ayayiqonda ixabiso lokubonelela ngokutshaja ngokukhawuleza kwe-DC. Nangona kunjalo, impumelelo yesikhululo sokutshaja imiselwa kudala ngaphambi kokuba imoto yokuqala ifakelwe. Ukufakelwa kobuchwephesha kunye nocwangciso lwendawo olucwangcisiweyo ziintsika ezimbini zeprojekthi yokutshaja ye-EV ephumelelayo. Esi sikhokelo sihlola iindlela ezilungileyo zokufaka izitishi ze-DC ezixhonywe eludongeni ze-MIDA's 40kW, 60kW, kunye ne-80kW ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokusetyenziswa okuphezulu kwendawo.

Inyathelo 1: Uvavanyo loMbane kunye noVavanyo lweGridi

Ngaphambi kokukhetha indawo ebonakalayo, uvavanyo olucokisekileyo lweziseko zombane zesiza luyimfuneko. Iitshaja ze-DC ze-MIDA zizixhobo ezinamandla aphezulu ezifuna umbane oqinileyo onezigaba ezi-3.

Iimfuno zamandla

Kwitshaja engama-80kW, ukutsalwa kombane ophezulu kungadlula i-120A. Kucetyiswa ukuba ufake i-sub-panel ezinikeleyo eneMolded Case Circuit Breaker (MCCB) elinganiswe ngokuphindwe kayi-1.25 kunombane olinganisiweyo wetshaja. Umzekelo, iyunithi engama-60kW idla ngokufuna ubuncinane i-125A breaker ukuze ikwazi ukusingatha ukutshaja komthwalo opheleleyo okuqhubekayo.

Iprotokholi yokuGcina umhlaba (yokuGcina umhlaba)

Iitshaja ze-MIDA ziquka inkqubo yokujonga umhlaba enobuchule. Ukumelana nomhlaba kufuneka kube ngaphantsi kwe-4Ω. Kwiindawo ezinomoya ophantsi, iintonga zomhlaba ezongezelelweyo okanye i-groundfill ekhethekileyo inokufuneka. Itshaja ayizukuyiqala ukuba ibona uqhagamshelo lomhlaba olunganelanga, nto leyo ekhusela imoto kunye nomqhubi kwiimpazamo zombane ezinokubakho.

Inyathelo lesi-2: Ukukhethwa kweSayithi eCwangcisiweyo

Into "efakelwe eludongeni" yeyona nzuzo inkulu ye-MIDA, evumela ucwangciso lwesiza oluyilwe ngendlela eyiyo olungenakulinganiswa neeyunithi ezime phantsi.

Ukuphucula Indawo

Kwiigaraji zokupaka okanye kwiindawo zokupaka ezixineneyo zasezidolophini, yonke imitha yesikwere ibalulekile. Ukufaka iyunithi yokutshaja eludongeni okanye kwintsika yesakhiwo kugcina indawo yomgangatho icocekile, kuthintela ukungqubana kwezithuthi kwaye kube lula ukugcinwa.

Ulawulo lweeCable kunye nokuFikeleleka

Khetha indawo evumela intambo yokutshaja yemitha ezi-5 (okanye eyokuzikhethela yemitha ezi-7) ukuba ifikelele lula kwindawo yokungena yesithuthi, nokuba imoto ipakwe ngentloko okanye ingasemva. I-holster yesibhamu sokutshaja kufuneka ibekwe kubude be-1.2 ukuya kwi-1.4 yeemitha ukuze ihambelane ne-ADA kwaye kube lula ukuyisebenzisa.

Inyathelo lesi-3: Ukufakelwa kunye nokuFakelwa ngokwasemzimbeni

Uthotho lwe-MIDA WY lwenzelwe ukuba kube lula ukuyifaka, kodwa ubunzima bayo (ngesiqhelo buphakathi kwe-60kg ukuya kwi-90kg kuxhomekeke kumlinganiselo wamandla) bufuna indawo eqinileyo yokuyibeka.

Iindawo zokuFaka

Iindonga zekhonkrithi eziqinisiweyo zilungile. Ukuba uzifaka kwiindonga zezitena okanye zeebhloko, sebenzisa iibholiti zokwandisa ezinzima okanye iibholiti ezisebenzisa ipleyiti yokuxhasa. Kwiindawo ezingenaludonga olufanelekileyo, i-MIDA inikezela ngesiseko sentsimbi esikhethekileyo, esiguqula iyunithi ibe sisikhululo esincinci, esime phantsi.

Izinto eziqwalaselwayo kwiNdalo

Nangona iiyunithi zilinganiswe nge-IP54 yokusetyenziswa ngaphandle, ukubonelela nge-canopy engaphezulu kunokwandisa ubomi beyunithi ngokuyikhusela kwimitha ye-UV ethe ngqo kunye nemvula enkulu. Qinisekisa ukuba kukho ubuncinane i-30cm yendawo ecacileyo ejikeleze indawo yokungenisa umoya kunye nee-exhaust vents ukuthintela ukuxinana kobushushu.

Inyathelo lesi-4: Ukufaka iintambo kunye noKhuseleko loMlilo

Ukudibanisa iintambo ngokuchanekileyo kukwahluka phakathi kwenkqubo ethembekileyo kunye nengozi yomlilo. I-MIDA icebisa ukusebenzisa iintambo ezixhonyiweyo zekopolo (ezifana nothotho lwe-YJV-0.6/1kV) ngenxa yokuqina kwazo kunye neempawu zazo zobushushu ezibalaseleyo.

Ukungena kunye nokutywina iCable

Iintambo kufuneka zingene kwitshaja zisuka ezantsi ngee-glands ezikhethiweyo. Emva kokufakwa, kubalulekile ukusebenzisa i-sealant engatshiyo yomgangatho wezoshishino (udongwe lomlilo) ukuvala zonke iindawo zokungena. Oku akuthinteli nje kuphela ukungena komswakama kodwa kukwagcina neempuku zingangeni—isizathu esiqhelekileyo kodwa esingananzwayo see-short circuits kwizixhobo zombane zangaphandle.

Inyathelo lesi-5: Ukugunyazisa kunye noLawulo loMthwalo

Nje ukuba ufakelo lugqityiwe, isigaba sokusebenza siyaqala. Iitshaja ze-MIDA zixhasa ukulinganisela umthwalo nge-RS485 okanye i-Ethernet. Ukuba iitshaja ezininzi zifakwe kwindawo enye, zinokuthethana ukuqinisekisa ukuba umbane uphela awudluli kumthamo wesakhiwo, nto leyo ethintela ukuphuculwa kwegridi okubizayo.

Isiphelo: Ukuqinisekisa Ikamva Lesiza Sakho

Ukufaka isikhululo se-DC esixhonywe eludongeni se-MIDA lutyalo-mali kwixesha elizayo. Ngokulandela ezi zikhokelo zokucwangcisa indawo kunye nokufakela, uqinisekisa ukuba iziseko zakho zokutshaja zikhuselekile, zisebenza kakuhle, kwaye zilungele ukukhuliswa. Nokuba ufaka iyunithi enye ye-40kW yegaraji yabucala okanye iqela lezikhululo ze-80kW zeenqwelo zorhwebo, isitshixo sempumelelo sikwisicwangciso sobuchwephesha kunye nobunjineli obuphezulu be-MIDA.
