Imoto yombane: umngcipheko wokufikelela kwiindawo ezisebenzayo kwitshaja (iklasi 1) emotweni ngenxa yokutshatyalaliswa kokhuseleko olusisiseko (iingozi, ukugcinwa kwemoto, njl.
Indawo ezimanzi okanye ezinamanzi anetyuwa (ikhephu kwindawo yokungena kwezithuthi zombane, imvula…)

Ukuthatha le mingcipheko inyukayo, IEC 60364-7-722 ithi:

Ukhuseleko olongezelelweyo nge-RCD 30mA kunyanzelekile
Inkqubo yokukhusela "ukubeka ngaphandle ukufikelela", ngokwe-IEC 60364-4-41 isiHlomelo B2, ayivumelekanga
Amanyathelo okhuseleko akhethekileyo ngokwe-IEC 60364-4-41 Isihlomelo C awavumelekanga
Ukwahlulwa kombane kunikezelo lwento enye yezixhobo ezisetyenziswayo ngoku kwamkelwa njengenyathelo lokhuselo kunye nesiguquli esizimeleyo esithobela i-IEC 61558-2-4, kwaye umbane wesekethe eyahluliweyo awuyi kuba ngaphezulu kwe-500 V. Esi sisetyenziswa ngokuqhelekileyo Isisombululo seNdlela 4.

Ukukhuselwa kukothuka kombane ngoqhawulo oluzenzekelayo lonikezelo

Imihlathi engezantsi ibonelela ngeemfuno ezineenkcukacha ze-IEC 60364-7-722: imigangatho ka-2018 (esekwe kwiCandelo 411.3.3, 531.2.101, kunye no-531.2.1.1, njl.).

Indawo nganye yokudibanisa i-AC iya kukhuselwa ngokukodwa sisixhobo esishiyekileyo sangoku (i-RCD) esinentsalela yokusebenza yangoku engagqithiyo kwi-30 mA.

Ii-RCDs zikhusela indawo nganye yokuxhuma ngokungqinelana ne-722.411.3.3 iya kuthi ihambelane ubuncinci neemfuno zohlobo lwe-RCD A kwaye iya kuba nentsalela yokusebenza elinganisiweyo yangoku engekho ngaphezulu kwe-30 mA.

Apho isikhululo sokutshaja se-EV sixhotyiswe nge-socket-outlet okanye isinxibelelanisi sezithuthi esithobela i-IEC 62196 (onke amalungu - "Iiplagi, iindawo ezikhutshelwa khona, izihlanganisi zezithuthi kunye neendawo zokungena kwezithuthi - Ukutshaja okusebenzayo kwezithuthi zombane"), amanyathelo okhuselo nxamnye nephutha leDC Okwangoku kuya kuthathwa, ngaphandle kwaxa kubonelelwe sisikhululo sokutshaja se-EV.

Olu thintelo lusekwe kwi-DC max yangoku eyamkelekileyo ngohlobo A RCDs ngokwemigangatho ye-IEC 61008/61009. Jonga umhlathi olandelayo ngolwazi oluthe kratya kumngcipheko wokumfamekisa kunye nezisombululo ezinciphisa ifuthe kunye nokwandisa ufakelo.

Kubalulekile: ezi zizisombululo ezibini kuphela ezihambelana nomgangatho we-IEC 60364-7-722 wokukhusela kukothuka kombane. Abanye abavelisi be-EVSE bathi banikezela "ngezixhobo ezikhuselweyo ezakhiweyo" okanye "ukhuselo olungisiweyo". Ukufumana okuninzi malunga nobungozi, kunye nokukhetha isisombululo esikhuselekileyo sokutshaja, jonga kwiPhepha leNgcacisonkqubo elinemilinganiselo yoKhuseleko yokutshaja izithuthi zombane

Ungalwenza njani ukhuseleko lwabantu kulo lonke ufakelo ngaphandle kobukho bemithwalo evelisa imisinga yokuvuza kweDC

Itshaja ze-EV zibandakanya iinguqulelo ze-AC / DC, ezinokuthi zivelise ukuvuza kwangoku kwe-DC. Oku kuvuza okwangoku kwe-DC kudluliswa kukhuseleko lwe-RCD yesekethe (okanye i-RCD + RDC-DD), ide ifike kwi-RCD / RDC-DD DC yexabiso lokukhubeka.

Ubuninzi be-DC yangoku enokuhamba kwisekethe ye-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 yohlobo A (okanye F) + 6mA RDC-DD (ngokwe-IEC 62955)

Kutheni le DC yokuvuza ngoku inokuba yingxaki kwezinye ii-RCD zofakelo

Ezinye ii-RCDs kufakelo lombane zinokuthi "zibone" le DC yangoku, njengoko kubonisiwe kwi-Fig.

I-RCDs ephezulu iya kubona i-100% ye-DC yokuvuza ngoku, nokuba yeyiphi na inkqubo yomhlaba (TN, TT)
Ii-RCDs ezifakwe ngokuhambelana ziya kubona kuphela isahlulo sale nkqubo yangoku, kuphela kwinkqubo yomhlaba we-TT, kwaye kuphela xa kukho isiphoso kwisekethe abayikhuselayo. Kwinkqubo yomhlaba we-TN, i-DC yokuvuza ngoku ihamba ngohlobo lwe-B RCD ibuyela umva nge-PE conductor, kwaye ke ayinakubonwa yi-RCDs ngokuhambelana.

Umzobo. I-EV26-Ii-RCDs kuthotho okanye ngokuhambelana zichaphazeleka kukuvuza okukhoyo ngoku kwe-DC okuvunyelwe ngohlobo B RCD

Ii-RCDs ngaphandle kohlobo B azenzelwanga ukuba zisebenze ngokuchanekileyo kubukho be-DC yokuvuza okukhoyo, kwaye mhlawumbi "kumfanyekisiwe" ukuba le yangoku iphezulu kakhulu: eyona nto ibalulekileyo iya kuba yimagnethi yile DC yangoku kwaye isenokungakhathali kwimpazamo ye-AC Okwangoku, umz. i-RCD ayisayi kuphinda ikhubeke kwimeko yeempazamo ze-AC (imeko enokuba yingozi). Oku ngamanye amaxesha kubizwa ngokuba "kukumfama", "ukumfamekisa" okanye ukungafuneki kwe-RCDs.

Imigangatho ye-IEC ichaza (ubuninzi) be-DC offset esetyenziselwa ukuvavanya ukusebenza ngokuchanekileyo kweentlobo ezahlukeneyo ze-RCD:

10 mA yohlobo F,
I-6 mA yohlobo A
kunye ne-0 mA yohlobo AC.

Oko kukuthi, kuthathelwa ingqalelo iimpawu ze-RCDs njengoko kuchaziwe yimigangatho ye-IEC:

Uhlobo lwe-RCDs AC alunakufakwa ngakwisikhululo sokutshaja se-EV, ngaphandle kokukhetha i-EV RCD (uhlobo B, okanye uhlobo A + RDC-DD)
Uhlobo lwe-RCDs A okanye u-F unokufakwa ngakwindawo ephezulu yesikhululo se-EV, kwaye kuphela ukuba esi sikhululo sokutshaja se-EV sikhuselwe luhlobo lwe-RCD A (okanye F) + 6mA RCD-DD

Uhlobo lwe-RCD A / F + 6mA RDC-DD isisombululo asinampembelelo incinci (isiphumo sokuqhwanyaza kancinci) xa ukhetha ezinye ii-RCDs, nangona kunjalo, ikwanomda kakhulu ekusebenzeni, njengoko kubonisiwe kwi Ikhiwane. EV27.

Umzobo. EV27 - Esona sikhululo siphezulu se-EV sikhuselwe luhlobo lwe-RCD A / F + 6mA RDC-DD inokufakwa emazantsi e-RCDs uhlobo A kunye no-F

Iingcebiso zokuqinisekisa ukusebenza ngokuchanekileyo kwee-RCDs kufakelo

Ezinye zezisombululo ezinokubakho zokunciphisa ifuthe leesekethe ze-EV kwezinye ii-RCD zofakelo lombane:

Qhagamshela ii-EV zokutshaja iisekethi phezulu kakhulu kulwakhiwo lombane, ukuze zihambelane nezinye iRCDs, ukunciphisa kakhulu umngcipheko wokumfamekisa.
Sebenzisa inkqubo ye-TN ukuba kunokwenzeka, njengoko kungekho siphumo sokumfamekisa kwii-RCD ngokuhambelana
Kwii-RCDs ezikhulayo zeesekethe zokutshaja ze-EV, nokuba

khetha uhlobo B RCDs, ngaphandle kokuba unetshaja ye-1 kuphela esebenzisa uhlobo A + 6mA RDC-DDor

khetha ii-RCDs ezingezizo ezohlobo lwe-B ezenzelwe ukumelana namaxabiso ama-DC angaphaya kwamaxabiso achaziweyo afunekayo kwimigangatho ye-IEC, ngaphandle kokuchaphazela ukusebenza kwabo kukhuseleko lwe-AC. Umzekelo omnye, kunye nohlu lweemveliso zombane zeSchneider: uhlobo lweActi9 300mA uhlobo lwee-RCDs lunokusebenza ngaphandle kokumfamekisa ukusebenza ukuya kuthi ga kwi-4 EV yokutshaja imijikelezo ekhuselwe zii-30mA zohlobo lwe-RCDs. Ngolwazi oluthe kratya, nxibelelana nesikhokelo soKhuselo lweMpazamo yoMbane weXXX oquka iitafile zokukhetha kunye nokukhetha kwidijithali.

Unokufumana iinkcukacha ezithe kratya kwisahluko F - ii-RCDs ezikhethiweyo kubukho bamaza okuvuza komhlaba e-DC (ikwasebenza nakwiimeko ngaphandle kokutshaja kwe-EV).

Ukukhuselwa kokukhusela i-EVSE yangaphakathi-ufakelo kusetyenziswa ibhasi-ngaphandle kwenkqubo yokukhusela umbane (i-LPS) -ukufikelela koluntu

Lo mzekelo uyafana nowangaphambili, ngaphandle kokuba ibhasi (inkqubo ye-busbar trunking system) isetyenziselwa ukuhambisa amandla kwi-EVSE.

Umzobo. I-EV31 -Ukhuselo lokunyuka kwe-EVSE yangaphakathi-ngaphandle kwenkqubo yokukhusela umbane (i-LPS) -ukufakwa kusetyenziswa ibhasi-ukufikelela koluntu

Kule meko, njengoko kubonisiwe kwi Ikhiwane.

Uhlobo lwe-2 SPD luyafuneka kwi-switchboard ye-voltage esezantsi (MLVS)
Ii-EVSE zinikezelwa zisemgceni webhasi, kwaye ii-SPDs (ukuba ziyafuneka) zifakelwe ngaphakathi kweebhokisi zebhasi
Uhlobo olongezelelweyo lwe-2 SPD luyafuneka kwindawo yokuqala yokuphuma kwebhasi eyondla i-EVSE (ngokubanzi umgama oya kwi-MLVS ungaphezulu kwe-10m). Ezi EVSE zilandelayo zikhuselwe yile SPD ukuba zingaphantsi kwe-10m kude
Ukuba olu hlobo longezelelweyo 2 SPD luye phezulu <1.25kV (e (8/20) = 5kA), akukho mfuneko yokongeza nayiphi na enye i-SPD kwindlela yebhasi: zonke ezi zilandelayo ze-EVSE zikhuselekile.
Uhlobo lwe-3 SPD luyacetyiswa kwakhona kwiNkqubo yokuLawulwa kweMithwalo (i-LMS) njengezixhobo ze-elektroniki ezibuthathaka. Olu hlobo lwe-3 SPD kufuneka lufakelwe ezantsi luhlobo lwe-2 SPD (olucetyiswa ngokubanzi okanye olufunekayo kwibhodi yokutshintsha apho i-LMS ifakwe khona).

Umzobo. EV32 -Ukhuselo lokunyuka kwe-EVSE yangaphakathi-ngenkqubo yokukhusela umbane (i-LPS) -ukufikelela koluntu

Xa isakhiwo sikhuselwe yinkqubo yokhuseleko yombane (LPS):

Uhlobo lwe-1 + 2 SPD luyafuneka kwi-switchboard ye-voltage esezantsi (MLVS)
I-EVSE nganye inikwa isekethe ezinikeleyo.
Uhlobo olongezelelweyo lwe-2 SPD luyafuneka kwi-EVSE nganye, ngaphandle kokuba umgama ukusuka kwipaneli ephambili ukuya kwi-EVSE ungaphantsi kwe-10m.
Uhlobo lwe-3 SPD luyacetyiswa kwakhona kwiNkqubo yokuLawulwa kweMithwalo (i-LMS) njengezixhobo ze-elektroniki ezibuthathaka. Olu hlobo lwe-3 SPD kufuneka lufakelwe ezantsi luhlobo lwe-2 SPD (olucetyiswa ngokubanzi okanye olufunekayo kwibhodi yokutshintsha apho i-LMS ifakwe khona).

Qaphela: ukuba usebenzisa ibhasi xa usasaza, sebenzisa imigaqo eboniswe kumzekelo ngaphandle kwe-LTS, ngaphandle kwe-SPD kwi-MLVS = sebenzisa udidi 1 + 2 SPD hayi uhlobo 2, ngenxa ye-LPS.

Umzobo. I-EV33 -Ukhuselo lonyuko lwangaphandle ngaphandle kwenkqubo yokukhusela umbane (i-LPS) -ukufikelela koluntu

Kulo mzekelo:

Uhlobo lwe-2 SPD luyafuneka kwi-switchboard ye-voltage esezantsi (MLVS)
Uhlobo olongezelelweyo lwe-2 SPD luyafuneka kwipaneli esezantsi (umgama ngokubanzi> i-10m ukuya kwi-MLVS)

Ukwengeza:

Xa i-EVSE idityaniswe nolwakhiwo:
Sebenzisa uthungelwano lwezixhobo lwesakhiwo
ukuba i-EVSE ingaphantsi kwe-10m ukusuka kwipaneli esezantsi, okanye ukuba ngaba uhlobo lwe-2 SPD efakwe kwipaneli esezantsi ine-Up <1.25kV (e (8/20) = 5kA), akukho mfuneko yokongezwa kwee-SPD KUNYE

Xa i-EVSE ifakiwe kwindawo yokupaka, kwaye inikezelwa ngombane wombane ongaphantsi komhlaba:

nganye i-EVSE iya kuxhotyiswa ngentonga yomhlaba.
I-EVSE nganye iya kudityaniswa kuthungelwano lwe-equipotential. Lomnatha kufuneka uqhagamshelwe kwinethiwekhi ye-equipotential yesakhiwo.
faka uhlobo lwe-2 SPD kwi-EVSE nganye
Uhlobo lwe-3 SPD luyacetyiswa kwakhona kwiNkqubo yokuLawulwa kweMithwalo (i-LMS) njengezixhobo ze-elektroniki ezibuthathaka. Olu hlobo lwe-3 SPD kufuneka lufakelwe ezantsi luhlobo lwe-2 SPD (olucetyiswa ngokubanzi okanye olufunekayo kwibhodi yokutshintsha apho i-LMS ifakwe khona).
