Ukushaja i-EV Ukushaja Ukuvikelwa

Ukushaja i-EV - ukwakhiwa kokufakwa kagesi

Ukushaja imoto kagesi kungumthwalo omusha wokufakwa kwamandla kagesi aphansi ongaletha izinselelo ezithile.

Izidingo ezithile zokuphepha nokuklama zinikezwa ku-IEC 60364 Ukufaka amandla kagesi anamandla aphansi - Ingxenye 7-722: Izidingo zokufakwa noma izindawo ezikhethekile - Izimpahla zezimoto zikagesi.

Umdwebo. I-EV21 inikeza ukubuka konke ngobubanzi bokusetshenziswa kwe-IEC 60364 yezindlela ezahlukahlukene zokushaja ze-EV.

[a] esimweni seziteshi zokushaja ezisemgwaqweni, “ukusethwa kwangasese kwe-LV” kuncane, kepha i-IEC60364-7-722 isasebenza kusukela endaweni yokuxhuma okusetshenziswayo kuye endaweni yokuxhuma ye-EV.

I-Fig. EV21 - Ububanzi bokusetshenziswa kwe-IEC 60364-7-722 standard, echaza izidingo ezithile lapho kuhlanganiswa ingqalasizinda yokushaja i-EV kokufaka okusha noma okukhona kwe-LV kagesi.

Kumele kuqashelwe futhi ukuthi ukuhambisana ne-IEC 60364-7-722 kwenza kuphoqeleke ukuthi izingxenye ezahlukahlukene zokufakwa kokushaja kwe-EV zihambisane ngokuphelele namazinga womkhiqizo we-IEC ahlobene. Isibonelo (akuphelelanga):

Isiteshi sokushaja se-EV (izindlela 3 no 4) kufanele zithobele izingxenye ezifanele zochungechunge lwe-IEC 61851.
Ama-Residual Current Devices (RCDs) kufanele athobele elinye lalawa mazinga alandelayo: IEC 61008-1, IEC 61009-1, IEC 60947-2, noma i-IEC 62423.
I-RDC-DD izothobela i-IEC 62955
Idivayisi evikela ngaphezulu izohambisana ne-IEC 60947-2, IEC 60947-6-2 noma i-IEC 61009-1 noma izingxenye ezifanele zochungechunge lwe-IEC 60898 noma uchungechunge lwe-IEC 60269.
Lapho iphoyinti lokuxhuma liyisokhethi-socket noma isixhumi semoto, lizothobela i-IEC 60309-1 noma i-IEC 62196-1 (lapho kungadingeki khona ukushintshana), noma i-IEC 60309-2, IEC 62196-2, IEC 62196-3 noma i-IEC TS 62196-4 (lapho kudingeka khona ukushintshana), noma izinga likazwelonke lama-socket-outlets, inqobo nje uma isilinganiso samanje singeqi ku-16 A.

Umthelela we-EV yokushaja ngokufunwa kwamandla okuphezulu kanye nobukhulu bemishini
Njengoba kushiwo ku-IEC 60364-7-722.311, “Kuzocatshangelwa ukuthi ngokusetshenziswa okujwayelekile, iphoyinti ngalinye lokuxhuma lisetshenziswa kumanje okulinganisiwe noma kusilinganiso samanje sokushaja esimisiwe sesiteshi sokushaja. Izindlela zokucushwa kwesilinganiso samanje sokushaja esiphezulu sizokwenziwa kuphela ngokusebenzisa ukhiye noma ithuluzi futhi kufinyeleleke kuphela kubantu abanamakhono noma abafundisiwe. ”

Usayizi wesifunda onikezela iphoyinti elilodwa lokuxhuma (imodi 1 no-2) noma isiteshi esisodwa sokushaja se-EV (imodi 3 no-4) kufanele wenziwe ngokuya ngobukhulu besikhathi sokushaja (noma inani eliphansi, uma nje ukumiswa kwaleli nani kungatholakali abantu abangenamakhono).

I-IEC 60364-7-722.311 ibuye ithi “Njengoba wonke amaphuzu wokuxhuma wokufaka angasetshenziswa ngasikhathi sinye, isici sokuhlukahluka kwesifunda sokusabalalisa sizothathwa silingane no-1 ngaphandle kokuthi kufakwe umthwalo wokulawula kumishini yokunikezela ye-EV noma efakiwe umfula, noma inhlanganisela yakho kokubili. ”

Isici sokuhlukahluka okufanele sicatshangelwe ngamashaja e-EV amaningi ngokulingana silingana no-1 ngaphandle kokuthi kusetshenziswa i-Load Management System (LMS) ukulawula la mashaja e-EV.

Ukufakwa kwe-LMS ukulawula i-EVSE ngakho-ke kunconywa kakhulu: kuvimbela ukwengamela, kuthuthukisa izindleko zengqalasizinda kagesi, futhi kunciphise izindleko zokusebenza ngokugwema ukuphakama kwezimfuno zamandla. Bheka i-EV ishaja- izakhiwo zikagesi njengesibonelo sezakhiwo ezine-LMS nangaphandle kwayo, okukhombisa ukwenziwa okuzuziwe ekufakweni kukagesi. Bheka ukushaja kwe-EV - ukwakhiwa kwedijithali ngemininingwane eminingi ngokuhlukahluka okuhlukile kwe-LMS, namathuba angeziwe angenzeka ngezibalo ezisuselwa emafini kanye nokugadwa kokushaja kwe-EV. Futhi hlola izindlela zokushaja ze-Smart ngokuhlanganiswa okuhle kwe-EV ngezinhloso zokushaja okuhlakaniphile.

Ukuhlelwa kwama-conductor nezinhlelo zomhlaba

Njengoba kushiwo ku-IEC 60364-7-722 (Izigaba 314.01 kanye no-312.2.1):

Kuzonikezwa isekethe elizinikele lokudlulisa amandla lisuka / liye emotweni kagesi.
Kuhlelo lwe-TN earthing, isekethe elihlinzeka ngephoyinti lokuxhuma ngeke lifake umqhubi we-PEN

Kufanele futhi kuqinisekiswe ukuthi izimoto ezisebenza ngogesi ezisebenzisa iziteshi zokushaja zinemikhawulo ehlobene nezinhlelo ezithile zomhlaba: isibonelo, izimoto ezithile azikwazi ukuxhunywa ku-Mode 1, 2, no-3 kuhlelo lwe-IT earthing (Isibonelo: Renault Zoe).

Imithethonqubo emazweni athile ingafaka izidingo ezingeziwe eziphathelene nezinhlelo zomhlaba kanye nokuqapha ukuqhubeka kwe-PEN. Isibonelo: icala lenethiwekhi ye-TNC-TN-S (PME) e-UK. Ukuhambisana ne-BS 7671, esimweni sekhefu elikhuphukayo le-PEN, ukuvikelwa okuhambisanayo okususelwa ekuqapheni kwamandla kufanele kufakwe uma ingekho i-electrode yendawo yasendaweni.

Ukuvikelwa ekuhlaselweni ugesi

Izicelo zokushaja i-EV zandisa ubungozi bokushaqeka kagesi, ngenxa yezizathu eziningana:

Ama-plugs: ubungozi bokuyekiswa kokuqhutshwa koMvikeli Womhlaba Wokuvikela (PE).
Ikhebula: ubungozi bokulimazeka kwemishini ekwehlukanisweni kwekhebula (ukuchobozwa ngokugingqika kwamathayi emoto, ukusebenza okuphindaphindwayo…)
Imoto kagesi: ubungozi bokufinyelela ezingxenyeni ezisebenzayo zeshaja (isigaba 1) emotweni ngenxa yokucekelwa phansi kokuvikelwa okuyisisekelo (izingozi, ukugcinwa kwemoto, njll.)
Izindawo ezimanzi noma zamanzi anosawoti (iqhwa onlet yemoto kagesi, imvula…)

Ukubheka lezi zingozi ezandisiwe, i-IEC 60364-7-722 ithi:

Ukuvikelwa okungeziwe nge-RCD 30mA kuphoqelekile
Izindlela zokuvikela "ukubeka lapho kungatholakali khona", ngokusho kwe-IEC 60364-4-41 Annex B2, azivunyelwe
Izinyathelo ezikhethekile zokuvikela ngokwe-IEC 60364-4-41 Annex C azivunyelwe
Ukwehlukaniswa kukagesi kokuphakwa kwento eyodwa yemishini esetshenziswa njengamanje kwamukelwa njengendlela yokuvikela nge-transformer ehlukanisayo ehambisana ne-IEC 61558-2-4, futhi amandla wesekethe ahlukanisiwe ngeke adlule ama-500 V. Isixazululo seModi 4.

Ukuvikelwa ekuhlaselweni ugesi ngokunqanyulwa okuzenzakalelayo kokuphakelayo

Izigaba ezingezansi zinikeza izidingo eziningiliziwe ze-IEC 60364-7-722: ejwayelekile ka-2018 (ngokususelwa kuzigaba 411.3.3, 531.2.101, no-531.2.1.1, njll.).

Indawo ngayinye yokuxhuma ye-AC izovikelwa ngawodwana wensali eyinsalela (i-RCD) enensalela yokusebenza yamanje esalayo engeqi kuma-30 mA.

Ama-RCD avikela indawo ngayinye yokuxhuma ngokuya ngo-722.411.3.3 kufanele ahambisane okungenani nezidingo zohlobo lwe-RCD A futhi azoba nensalela yokusebenza elinganiselwe esingeqile kuma-30 mA.

Lapho isiteshi sokushaja i-EV sine-socket-outlet noma isixhumi semoto esihambisana ne-IEC 62196 (zonke izingxenye - “Ama-plug, amasokhethi, izixhumi zezimoto kanye nezindawo zokungena ezimotweni - Ukushaja okusebenzayo kwezimoto zikagesi”), izindlela zokuvikela iphutha le-DC Okwamanje kuzothathwa, ngaphandle kwalapho kuhlinzekwa khona yisiteshi sokushaja se-EV.

Izinyathelo ezifanele, zephoyinti ngalinye lokuxhuma, zizoba ngale ndlela elandelayo:

Ukusetshenziswa kohlobo lwe-RCD B, noma
Ukusetshenziswa kohlobo lwe-RCD A (noma F) ngokuhlangana ne-Residual Direct Current Detecting Device (RDC-DD) ehambisana ne-IEC 62955

Ama-RCDs kufanele athobele elinye lamazinga alandelayo: IEC 61008-1, IEC 61009-1, IEC 60947-2 noma IEC 62423.

Ama-RCDs azonqamula bonke abaqhubi ababukhoma.

I-Fig. EV23 ne-EV24 ngezansi zifingqa lezi zidingo.

Akufaneleki

(alikho iphoyinti lokuxhuma le-AC nokuhlukaniswa ngogesi)

amanothi:

i-RCD noma imishini efanele eqinisekisa ukunqanyulwa kokuphakelayo uma kwenzeka iphutha le-DC ingafakwa ngaphakathi kwesiteshi sokushaja se-EV, ebhodini lokushintshana elikhuphukayo, noma kuzo zombili izindawo.
Izinhlobo ezithile ze-RCD njengoba kukhonjisiwe ngenhla ziyadingeka ngoba isiguquli se-AC / DC sifakiwe ezimotweni zikagesi, futhi ezisetshenziselwa ukushaja ibhethri, zingahle zikhiqize ukuvuza kwamanje kweDC.

Yini inketho oyithandayo, i-RCD yohlobo B, noma uhlobo lwe-RCD A / F + RDC-DD 6 mA?

Indlela esemqoka yokuqhathanisa lezi zixazululo ezimbili umthelela ongaba khona kwamanye ama-RCD ekufakweni kukagesi (ubungozi bokuphuphuthekisa), kanye nokuqhubeka okulindelekile kwensizakalo yokushaja i-EV, njengoba kukhonjisiwe ku-Fig. EV25.

Lokhu kukhawulelwa kususelwa esikhathini samanje se-DC esamukelekayo ngohlobo A RCDs ngokwamazinga we-IEC 61008/61009. Bheka isigaba esilandelayo ukuthola eminye imininingwane engcupheni yokuphuphuthekisa kanye nezixazululo ezinciphisa umthelela futhi zikhulise ukufakwa.

Okubalulekile: lezi izixazululo ezimbili kuphela ezihambisana nezinga le-IEC 60364-7-722 lokuvikelwa ekushayweni ugesi. Abanye abakhiqizi be-EVSE bathi banikela "ngezinto zokuvikela ezakhelwe ngaphakathi" noma "ukuvikelwa okushumekiwe". Ukuthola kabanzi ngobungozi, nokukhetha isisombululo esiphephile sokushaja, bheka iPhepha Elimhlophe elinesihloko esithi Izinyathelo Zokuphepha zokushaja izimoto zikagesi

Ungakusebenzisa kanjani ukuvikelwa kwabantu kukho konke ukufakwa yize kukhona imithwalo ekhiqiza imisinga yokuvuza ye-DC

Amashaja e-EV afaka izinguquko ze-AC / DC, ezingakhiqiza ukuvuza kwamanje kwe-DC. Lokhu kuvuza okukhona manje kwe-DC kudluliswa ukuvikelwa kwe-RCD yesekethe (noma i-RCD + RDC-DD), ize ifike kunani lokukhubeka le-RCD / RDC-DD DC.

Isilinganiselo samanje se-DC esingageleza ngesifunda se-EV ngaphandle kokukhubeka yile:

I-60 mA ye-30 mA RCD yohlobo B (2 * IΔn ngokwe-IEC 62423)
I-6 mA ye-30 mA RCD Uhlobo A (noma i-F) + 6mA RDC-DD (ngokwe-IEC 62955)

Kungani le DC evuzayo njengamanje ingaba yinkinga kwamanye ama-RCD wokufakwa

Amanye ama-RCD ekufakweni kukagesi "angabona" le DC yamanje, njengoba kukhonjisiwe ku-Fig. EV26:

Ama-RCD akhuphukayo azobona i-100% yamanje yokuvuza kwe-DC, noma ngabe yiluphi uhlelo lomhlaba (TN, TT)
Ama-RCD afakwe ngokufana azobona kuphela ingxenye yalokhu kwamanje, kuphela ngohlelo lwe-TT earthing, futhi kuphela lapho iphutha livela esifundeni abasivikelayo. Kuhlelo lwe-TN earthing, i-DC yokuvuza okuhamba ngohlobo B RCD ibuyela emuva kumqhubi we-PE, ngakho-ke ayinakubonwa yi-RCDs ngokufana.

Umdwebo. I-EV26 - Ama-RCDs ochungechungeni noma ngokufana athintwa yimanje yokuvuza kwe-DC edluliswa ngohlobo B RCD

Ama-RCD ngaphandle kohlobo B aklanyelwanga ukusebenza kahle lapho kukhona ukuvuza okukhona manje kwe-DC, futhi mhlawumbe "kuphuphuthekiswe" uma lokhu kwamanje kuphakeme kakhulu: umnyombo wazo uzokwenziwa amandla kazibuthe ngalo mzuzu we-DC futhi ungahle ungabi nandaba nephutha le-AC njengamanje, isb. i-RCD ngeke isakhubeka uma kwenzeka kunephutha le-AC (isimo esingahle sibe yingozi). Lokhu kwesinye isikhathi kubizwa ngokuthi "ubumpumputhe", "ukuphuphuthekisa" noma ukukhubazeka kwama-RCD.

Izindinganiso ze-IEC zichaza i-offset ye-DC (ephezulu) esetshenziselwa ukuhlola ukusebenza okulungile kwezinhlobo ezahlukene zama-RCD:

10 mA yohlobo F,
6 mA yohlobo A
kanye no-0 mA wohlobo AC.

Lokho kusho ukuthi, ngokubheka izici zama-RCDs njengoba kuchazwe ngamazinga e-IEC:

Uhlobo lwe-RCDs AC alunakufakwa ngenhla kwanoma yisiphi isiteshi sokushaja se-EV, ngaphandle kwenketho ye-EV RCD (uhlobo B, noma thayipha A + RDC-DD)
Uhlobo lwe-RCDs A noma u-F lungafakwa ngenhla kwesiteshi esisodwa sokushaja se-EV, futhi kuphela uma lesi siteshi sokushaja se-EV sivikelwe ngohlobo lwe-RCD A (noma F) + 6mA RCD-DD

Isixazululo se-RCD yohlobo A / F + 6mA RDC-DD sinomthelela omncane (umphumela ocwayiza kancane) lapho kukhethwa amanye ama-RCD, noma kunjalo, futhi kukhawulwe kakhulu ekusebenzeni, njengoba kukhonjisiwe ku-Fig. EV27.

I-Fig. EV27 - Isiteshi esisodwa se-EV esivikelwe uhlobo lwe-RCD A / F + 6mA RDC-DD singafakwa ezansi nomfula wohlobo lwe-RCDs A no-F

Izincomo zokuqinisekisa ukusebenza kahle kwama-RCD ekufakweni

Ezinye izixazululo ezikhona zokunciphisa umthelela wamasekethe e-EV kwamanye ama-RCD wokufakwa kukagesi:

Xhuma ama-EV wokushaja ama-circuits phezulu ngangokunokwenzeka ekwakhiweni kukagesi, ukuze afane namanye ama-RCD, ukunciphisa kakhulu ingozi yokuphuphuthekisa
Sebenzisa uhlelo lwe-TN uma kungenzeka, ngoba akunamphumela wokuvala amehlo kuma-RCD ngokufana
Kuma-RCDs akhuphuka amasekhethi wokushaja we-EV, noma

khetha uhlobo B RCDs, ngaphandle kokuthi uneshaja eyi-1 EV kuphela esebenzisa uhlobo A + 6mA RDC-DDor

khetha ama-RCD angama-B angewona uhlobo aklanyelwe ukumelana namanani wamanje e-DC angaphezu kwamanani acacisiwe adingeka kumazinga we-IEC, ngaphandle kokuthinta ukusebenza kwawo kokuvikela i-AC. Isibonelo esisodwa, ngamabanga womkhiqizo weSchneider Electric: uhlobo lwe-Acti9 300mA uhlobo A RCDs lungasebenza ngaphandle kokuphuphuthekisa ukusebenza lukhuphukele phezulu kuma-circuits ama-4 EV wokushaja avikelwe ama-Rm angama-30mA. Ngeminye imininingwane, thintana nomhlahlandlela we-XXXX Electric Earth Fault Protection ohlanganisa amatafula wokukhetha nezikhethi zedijithali.

Ungathola nemininingwane eminingi esahlukweni F - Ukukhethwa kwe-RCDs lapho kukhona imisinga yokuvuza komhlaba ye-DC (futhi isebenza kuzimo ezithile ngaphandle kokushaja i-EV).

Izibonelo ze-EV ukushaja imidwebo kagesi

Ngezansi kunezibonelo ezimbili zemidwebo kagesi yamasekhethi wokushaja we-EV kwimodi 3, ehambisana ne-IEC 60364-7-722.

I-Fig. EV28 - Isibonelo somdwebo kagesi wesiteshi esisodwa sokushaja kumodi 3 (@home - application residential)

Ukuvikela ukuvikelwa ugesi ngohlobo lwe-30mA RCD yohlobo B (i-30mA RCD yohlobo A / F + RDC-DD 6mA nayo ingasetshenziswa)
I-RCD ekhuphukayo iwuhlobo A RCD. Lokhu kungenzeka kuphela ngenxa yezici ezithuthukisiwe zale-XXXX Electric RCD: ayikho ingozi yokuphuphuthekisa ngamandla okuvuza adluliswa ngohlobo B RCD
Iphinde ihlanganise iSurge Protection Device (kunconyiwe)

I-Fig. EV29 - Isibonelo somdwebo kagesi wesiteshi esisodwa sokushaja (imodi 3) enezindawo ezi-2 zokuxhuma (uhlelo lokuhweba, ukupaka…)

Indawo ngayinye yokuxhuma inesifunda sayo esizinikele
Ukuvikelwa ekushayweni ugesi ngo-30mA RCD uhlobo B, okukodwa kwephoyinti ngalinye lokuxhuma (i-30mA RCD yohlobo A / F + RDC-DD 6mA nayo ingasetshenziswa)
Ukuvikelwa kwe-overvoltage nohlobo lwe-RCDs B kungafakwa esiteshini sokushaja. Uma kunjalo, isiteshi sokushaja singanikwa amandla kusuka ku-switchboard ngesifunda esisodwa se-63A
iMNx: eminye imithethonqubo yezwe ingadinga ukushintshwa okuphuthumayo kwe-EVSE ezindaweni zomphakathi
Ukuvikelwa kokuqubuka akuboniswa. Ingangezwa esiteshini sokushaja noma ebhodini lokushintsha elikhuphukayo (kuya ngebanga eliphakathi kweswitchboard nesiteshi sokushaja)

Ukuvikelwa kokuqhuma kwesikhashana

Ukukhuphuka kwamandla okwenziwe isiteleka sombani eduze kwenethiwekhi kagesi kusakazeka kunethiwekhi ngaphandle kokuncishiswa okuphawulekayo. Ngenxa yalokho, i-overvoltage engase ivele ekufakweni kwe-LV ingeqa amazinga amukelekayo wokumelana namandla kagesi anconywe ngamazinga e-IEC 60664-1 kanye ne-IEC 60364. Imoto kagesi, eklanyelwe isigaba sevoltage II ngokwe-IEC 17409, kufanele zivikelwe kuma-overvoltages angadlula ku-2.5 kV.

Ngenxa yalokho, i-IEC 60364-7-722 idinga ukuthi i-EVSE efakwe ezindaweni ezifinyeleleka emphakathini zivikelwe ekuqothulweni kwesikhashana. Lokhu kuqinisekiswa ngokusetshenziswa kohlobo lokuvikela noma lokuthayipha uhlobo lwesi-1 (SPD), oluhambisana ne-IEC 2-61643, efakwe ebhodini lokunikezela ngemoto kagesi noma ngqo ngaphakathi kwe-EVSE, ngezinga lokuvikela elingu-Up ≤ 11 kV.

Ukuvikelwa kokukhuphuka ngokuxhuma kwe-equipotential

Isivikelo sokuqala okufanele sisetshenziswe (i-conductor) esiqinisekisa ukubopha kwe-equipotential phakathi kwazo zonke izingxenye zokufakwa kwe-EV.

Inhloso ukubopha bonke abaqhubi abaphansi nezinsimbi ukuze kwakheke amandla alinganayo kuzo zonke izindawo ohlelweni olufakiwe.

Ukuvikelwa kokuqubuka kwe-EVSE yasendlini - ngaphandle kohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

I-IEC 60364-7-722 idinga ukuvikelwa ekuqubukeni kwesikhashana okwenziwe kuzo zonke izindawo ezinokufinyelela komphakathi. Imithetho ejwayelekile yokukhetha ama-SPD ingasetshenziswa (Bona isahluko J - Ukuvikelwa kwe-Overvoltage).

Umdwebo. EV30 - Ukuvikelwa kokuqubuka kwe-EVSE yasendlini - ngaphandle kohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

Lapho isakhiwo singavikelwe uhlelo lokuvikela umbani:

Uhlobo lwe-2 SPD luyadingeka ebhodini eyinhloko yamandla kagesi aphansi (MLVS)
I-EVSE ngayinye inikezwa isifunda esizinikezele.
Uhlobo olungeziwe lwe-2 SPD luyadingeka ku-EVSE ngayinye, ngaphandle kokuthi uma ibanga ukusuka kuphaneli elikhulu kuya ku-EVSE lingaphansi kuka-10m.
Uhlobo lwe-3 SPD nalo lunconyelwa iLoad Management System (LMS) njengemishini ye-elektroniki ebucayi. Lolu hlobo lwe-3 SPD kufanele lufakwe ezansi nohlobo lwe-2 SPD (okuvame ukunconywa noma kudingeke ebhodini lokushintsha lapho kufakwa khona i-LMS).

Ukuvikelwa kokuqubuka kwe-EVSE yasendlini - ukufakwa kusetshenziswa ibhasi - ngaphandle kohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

Lesi sibonelo sifana nesangaphambilini, ngaphandle kokuthi ibhasi (ibhasi trunking system) isetshenziselwa ukwaba amandla ku-EVSE.

I-Fig. EV31 - Ukuvikelwa kokuqubuka kwe-EVSE yasendlini - ngaphandle kohlelo lokuvikela umbani (LPS) - ukufakwa kusetshenziswa ibhasi - ukufinyelela komphakathi

Kulokhu, njengoba kukhonjisiwe ku-Fig. EV31:

Uhlobo lwe-2 SPD luyadingeka ebhodini eyinhloko yamandla kagesi aphansi (MLVS)
Ama-EVSE ahlinzekwa kusuka esitimeleni, futhi ama-SPD (uma kudingeka) afakwa ngaphakathi kwamabhokisi wokuthinta ibhasi
Uhlobo olungeziwe lwe-2 SPD luyadingeka ebhokisini lokuqala lokuphuma kwebhasi elondla i-EVSE (ngokujwayelekile ibanga eliya kwi-MLVS lingaphezu kwe-10m). Ama-EVSE alandelayo nawo avikelwe yile SPD uma engaphansi kwe-10m kude
Uma lolu hlobo olwengeziwe 2 SPD lune-Up <1.25kV (at I (8/20) = 5kA), asikho isidingo sokwengeza enye i-SPD esitimeleni: konke okulandelayo kwe-EVSE kuvikelwe.
Uhlobo lwe-3 SPD nalo lunconyelwa iLoad Management System (LMS) njengemishini ye-elektroniki ebucayi. Lolu hlobo lwe-3 SPD kufanele lufakwe ezansi nohlobo lwe-2 SPD (okuvame ukunconywa noma kudingeke ebhodini lokushintsha lapho kufakwa khona i-LMS).

Ukuvikelwa kokuqubuka kwe-EVSE yasendlini - ngohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

I-Fig. EV32 - Ukuvikelwa kokuqubuka kwe-EVSE yasendlini - ngohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

Lapho isakhiwo sivikelwe uhlelo lokuvikela umbani (LPS):

Uhlobo lwe-1 + 2 SPD luyadingeka ebhodini eyinhloko yamandla kagesi aphansi (MLVS)
I-EVSE ngayinye inikezwa isifunda esizinikezele.
Uhlobo olungeziwe lwe-2 SPD luyadingeka ku-EVSE ngayinye, ngaphandle kokuthi uma ibanga ukusuka kuphaneli elikhulu kuya ku-EVSE lingaphansi kuka-10m.
Uhlobo lwe-3 SPD nalo lunconyelwa iLoad Management System (LMS) njengemishini ye-elektroniki ebucayi. Lolu hlobo lwe-3 SPD kufanele lufakwe ezansi nohlobo lwe-2 SPD (okuvame ukunconywa noma kudingeke ebhodini lokushintsha lapho kufakwa khona i-LMS).

Qaphela: uma usebenzisa ibhasi yokuhambisa, sebenzisa imithetho ekhonjiswe kusibonelo ngaphandle kwe-LTS, ngaphandle kwe-SPD ku-MLVS = sebenzisa Uhlobo 1 + 2 SPD hhayi Uhlobo 2, ngenxa ye-LPS.

Ukuvikelwa kokuqubuka kwe-EVSE yangaphandle - ngaphandle kohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

I-Fig. EV33 - Ukuvikelwa kokuqubuka kwe-EVSE yangaphandle - ngaphandle kohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

Kulesi sibonelo:

Uhlobo lwe-2 SPD luyadingeka ebhodini eyinhloko yamandla kagesi aphansi (MLVS)
Uhlobo olungeziwe lwe-2 SPD luyadingeka kuphaneli engaphansi (ibanga ngokuvamile> 10m kuya kwi-MLVS)

Ngaphezu kwalokho:

Lapho i-EVSE ixhunywe nesakhiwo sokwakha:
sebenzisa inethiwekhi ye-equipotential yesakhiwo
uma i-EVSE ingaphansi kuka-10m ukusuka kuphaneli engaphansi, noma uma uhlobo 2 SPD olufakwe kuphaneli elingaphansi line-Up <1.25kV (at I (8/20) = 5kA), asikho isidingo sama-SPDs angeziwe ku NGOKWENZEKA

Lapho i-EVSE ifakwa endaweni yokupaka, futhi ihlinzekwa ngentambo kagesi engaphansi komhlaba:

i-EVSE ngayinye izofakwa ngenduku yokumisa umhlaba.
i-EVSE ngayinye izoxhunywa kunethiwekhi ye-equipotential. Le nethiwekhi kufanele futhi ixhunywe kunethiwekhi ye-equipotential yesakhiwo.
faka uhlobo 2 SPD ku-EVSE ngayinye
Uhlobo lwe-3 SPD nalo lunconyelwa iLoad Management System (LMS) njengemishini ye-elektroniki ebucayi. Lolu hlobo lwe-3 SPD kufanele lufakwe ezansi nohlobo lwe-2 SPD (okuvame ukunconywa noma kudingeke ebhodini lokushintsha lapho kufakwa khona i-LMS).

Ukuvikelwa kokuqubuka kwe-EVSE yangaphandle - ngohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

Umdwebo. EV34 - Ukuvikelwa kokuqubuka kwe-EVSE yangaphandle - ngohlelo lokuvikela umbani (LPS) - ukufinyelela komphakathi

Isakhiwo esikhulu sinenduku yombani (uhlelo lokuvikela umbani) ukuvikela isakhiwo.

Esimweni esinjalo:

Uhlobo lwe-1 SPD luyadingeka ebhodini eyinhloko yamandla kagesi aphansi (MLVS)
Uhlobo olungeziwe lwe-2 SPD luyadingeka kuphaneli engaphansi (ibanga ngokuvamile> 10m kuya kwi-MLVS)

Ngaphezu kwalokho:

Lapho i-EVSE ixhunywe nesakhiwo sokwakha:

sebenzisa inethiwekhi ye-equipotential yesakhiwo
uma i-EVSE ingaphansi kuka-10m kusuka kuphaneli engaphansi, noma uma uhlobo 2 SPD olufakwe kuphaneli elingaphansi line-Up <1.25kV (at I (8/20) = 5kA), asikho isidingo sokwengeza ama-SPDs angeziwe ku-EVSE

Lapho i-EVSE ifakwa endaweni yokupaka, futhi ihlinzekwa ngentambo kagesi engaphansi komhlaba:

i-EVSE ngayinye izofakwa ngenduku yokumisa umhlaba.
i-EVSE ngayinye izoxhunywa kunethiwekhi ye-equipotential. Le nethiwekhi kufanele futhi ixhunywe kunethiwekhi ye-equipotential yesakhiwo.
faka uhlobo 1 + 2 SPD ku-EVSE ngayinye

Uhlobo lwe-3 SPD nalo lunconyelwa iLoad Management System (LMS) njengemishini ye-elektroniki ebucayi. Lolu hlobo lwe-3 SPD kufanele lufakwe ezansi nohlobo lwe-2 SPD (okuvame ukunconywa noma kudingeke ebhodini lokushintsha lapho kufakwa khona i-LMS).
