GBT 18487.1-2015 waxa uu qeexayaa ereyga hadhaaga hadda jira sida soo socota: Residual current protector (RCD) waa qalabka wax lagu beddelo ee farsamada ama isku darka qalabka korantada ee shid kara, qaadi kara oo jebin kara wakhtiga ku jira xaaladaha shaqada ee caadiga ah, sidoo kalena kala gooya xidhiidhada marka hadda hadhaaga ahi waxa uu gaaraa qiime cayiman.Waa qalab beddela makaanik ama qalab koronto oo shid kara, qaadi kara oo jebin kara wakhtiga ku jira xaaladaha shaqada ee caadiga ah oo jebin kara xidhiidhada marka hadda hadhgu gaadho qiime cayiman marka la eego shuruudo cayiman.
Noocyada kala duwan ee difaaca hadda jira ayaa diyaar u ah xaalado ilaalin oo kala duwan iyo nooca ku habboon ee ilaalinta hadda jirta waa in loo doortaa muuqaalka si loo ilaaliyo.
Marka loo eego heerka caadiga ah ee hadhaaga hadda jira ee ka kooban astaamaha waxqabadka qaybta DC, ilaaliyayaasha hadda jira inta badan waxa loo qaybiyaa nooca AC ilaaliyeyaasha hadda hadhsan, nooca F ee ilaaliyayaasha hadda jira iyo nooca B.Shaqadoodu waa sidan soo socota.
Nooca AC haraaga hadda jira: sinusoidal AC haraaga hadda jira.
Nooca A haraaga difaaca hadda: nooca AC shaqada, garaaca DC hadhaaga hadda, garaaca DC haraaga hadda oo lagu kor saarayo 6mA oo siman DC hadda ah.
Nooca F ee difaaca hadda jira: Nooca A, hadhaaga hadda jira ee ka imanaya wareegyada ay ku shaqeeyaan wejiga iyo dhexdhexaadka ama wejiga iyo kirishbooyada dhexdhexaadka ah ee dhulka, garaaca hadhaaga DC ee hadda lagu kor saarayo socodka DC siman ee 10mA.
Nooca B ilaaliyaha hadda jira: Nooca F, sinusoidal AC haraaga hadda jira ee 1000Hz iyo ka hooseeya, AC haraaga hadda jira oo lagu kor saaray 0.4 jeer ficilka haraaga ah ee hadda jira ama 10mA siman DC hadda (halkii ka weyn), garaaca haraaga DC ee hadda lagu kor saaray 0.4 jeer lagu qiimeeyay hadhaaga dhaqdhaqaaqa hadda ama 10mA siman DC hadda (halkee ka weyn), hadda hadhaaga DC ee wareegyada la saxay, hadda siman ee DC haraaga.
Qaab dhismeedka aasaasiga ah ee xeesha sabuuradda ee EV guud ahaan waxaa ka mid ah shaandhaynta EMI ee qaybta wax gelinta, hagaajinta iyo PFC, wareegga awoodda beddelka, shaandhada EMI ee qaybta wax soo saarka, iwm. wareegga sixitaanka oo leh koronto-bixiye go'doon ah, halkaas oo Lg1, lg2 iyo capacitors kaaliyeyaasha ay sameeyaan shaandhada EMI-ga, L1, C1, D1, C3, Q5 waxay sameeyaan nooca kor-u-qaadista Marxaladda hore ee wareegga PFC, Q1, Q2, Q3, Q4, T1 , D2, D3, D4, D5 waxay sameeyaan wareegga beddelka awoodda ee marxaladda dambe, Lg3, lg4 iyo capacitors kaabayaal waxay sameeyaan shaandhada EMI wax soo saarka si loo yareeyo qiimaha ripple.
Inta lagu jiro isticmaalka baabuurka, waxaa hubaal ah inay jiri doonaan kuuskuus iyo gariir, gabowga aaladda iyo dhibaatooyinka kale ee laga yaabo inay ka dhigaan dahaarka gudaha xeedho baabuurka dhibaato, si dabaysha baabuurka ee habka ku dallaca AC meelo kala duwan oo ah falanqaynta qaabka guuldarada waxaa lagu heli karaa sida soo socota hababka failure.
(1) Ciladda dhulka ee dhinaca AC ee gelinta shabakada degmada, markaas oo cilada hadda taagan tahay inta jeer ee AC hadda.
(2) Ciladda dhulka ee qaybta toosiyaha, halkaas oo cilada hadda ay garaacday hadda DC.
(3) Ciladda dhulka ee DC/DC ee labada dhinac, marka cilada hadda jirta ay siman tahay DC hadda.
(4) Ciladda dhulka ee transformer-ka go'doominta, cilada hadda jirta waa AC hadda aan joogto ahayn.
Laga soo bilaabo nooca A ee hadhaaga ilaalinta hadda jira waa laga garan karaa, waxay ilaalin kartaa shaqada nooca AC, garaaca DC haraaga hadda jira, garaaca DC haraaga hadda jira ee ka sarreeya 6mA siman DC hadda, iyo dallayeeyaha DC cilladda hadda ≥ 6mA, Nooc Ilaaliyaha hadda jira ayaa laga yaabaa inuu u muuqdo mid dhuuban ama ma dhaqmi doono, taasoo keentay shaqada caadiga ah, ka dibna ilaaliyaha hadda jira ayaa lumin doona shaqada ilaalinta.
Heerka Yurub IEC 61851 kuma amrayo Nooca B, laakiin EVSE-yada leh Nooca A ee ilaaliyayaasha hadda jira, waxaa lagama maarmaan ah in sidoo kale la hubiyo in wareegga qaladka leh ee ka kooban DC ee ka badan 6mA la gooyo, mid ama mid kale.Marka lagu daro falanqaynta doorashada ilaalinta hadda jirta ee kor ku xusan, way caddahay in haddii ilaalinta khaladka sare la rabo in la daboolo, marka laga eego dhinaca badbaadada, nooca B ee hadhaaga hadda loo baahan yahay.
