Muva nje i-International Electrotechnical Commission EE igunyaze, yakhipha futhi yakhansela izinqumo ezimbalwa ze-CTL kumabhethri, okubandakanya ikakhulukazi izinga lesitifiketi esiphathwayo sebhethri i-IEC 62133-2, izinga lesitifiketi sebhethri yesitoreji samandla IEC 62619 kanye ne-IEC 63056. Okulandelayo okuqukethwe okuqondile kwesinqumo:

I-IEC 62133:2017, IEC 62133:2017 +I-AMD1:2021:khansela imfuneko ye-voltage yomkhawulo webhethri engu-60Vdc

NgoZibandlela wezi-2022, i-CTL yakhipha isinqumo sokuthi amandla kagesi emikhiqizo yephakethe lebhethri awakwazi ukudlula u-60Vdc. Asikho isitatimende esicacile mayelana nomkhawulo wamandla kagesi ku-IEC 62133-2, kodwa sisho izinga le-IEC 61960-3.

Isizathu esenza ukuthi lesi sinqumo sikhanselwe yi-CTL ukuthi “umkhawulo kagesi ophezulu ongu-60Vdc uzokhawulela imikhiqizo ethile yezimboni ukuthi ingene kulokhu kuhlolwa okujwayelekile, njengamathuluzi kagesi, njll.

I-IEC 62133:2017, IEC 62133:2017 +I-AMD1:2021:khansela imfuneko yokusebenza kwezinga lokushisa lokushaja

Ngokufanayo, esinqumweni sesikhashana esikhishwe ngoZibandlela wonyaka odlule, kwahlongozwa ukuthi lapho kushajwa ngendlela ye-Athikili 7.1.2 (edinga ukushaja emikhawulweni yokushisa yokushaja ephezulu nephansi), nakuba ku-Appendix A.4 yezinga elishiwoyo. ukuthi uma izinga lokushisa eliphezulu/eliphansi lokushaja lingeyena u-10℃/45℃, izinga lokushisa eliphezulu elilindelekile lidinga ukuba +5℃ kanye nezinga lokushisa eliphansi lokushaja lidinga -5℃. Nokho, ngesikhathi sokuhlolwa kwangempela, ukusebenza kuka-+/-5°C kungashiywa futhi ukushaja kungenziwa ngokuvumelana nezinga lokushisa elivamile eliphezulu/eliphansi lokushaja.

Lesi sinqumo saphasiswa emhlanganweni we-plenary ye-CTL walo nyaka.

I-IEC 62619: 2017: sebenzisa i-BMS ethuthukisiwe evela eceleni ukuze uhlole ukuphepha ekusebenzeni kwebhethri

Lokhu kulungiswa kumayelana nokuhlolwa kokuphepha komsebenzi wesistimu yebhethri ye-BMS.

Manje abakhiqizi abaningi bebhethri bathenga i-BMS kwabanye abantu, okungase kubangele ukuthi umkhiqizi webhethri angakwazi ukuqonda umklamo we-BMS onemininingwane. Lapho umenzeli wokuhlola enza ukuhlola kokuphepha okusebenzayo ngeSijobelelo H se-IEC 60730-1, umenzi akakwazi ukunikeza ngekhodi yomthombo ye-BMS.

Kulokhu, umenzeli wokuhlola angakwazi ukuhlola ikhodi yomthombo ngokuzimela nomkhiqizi we-BMS ukuze avikele amalungelo akhe empahla yobuhlakani. Ukuhlaziywa kokuphepha okusebenzayo kohlelo lwebhethri kubalulekile, futhi ukuhlola ngeke kukhanselwe ngenxa yokuthi umkhiqizi webhethri akakwazi ukuhlinzeka ngekhodi yomthombo.

Njengamanje, lesi sinqumo siseyisixazululo sesikhashana futhi sizovunywa emhlanganweni weqembu le-CTL ngo-2024.(PDSH 2230)

I-IEC 63056: 2020: i-voltage yokuhlola ukumelana ne-insulation

I-IEC 63056:2020 Isigaba somthetho 7.4 (Ukuhlolwa kokufakwa kukagesi ngesikhathi sokuthutha nokufakwa) sibhekisela ku-IEC 62133:2017 yokuhlolwa kokumelana nokufakwa. Leli iphutha lokuhlela. Ireferensi kufanele ibe yi-IEC 62133-2:2017. Leli phutha lazisiwe ku-IEC TC21A.

I-IEC 63056 ejwayelekile ingamboza imikhiqizo ene-voltage ephezulu ye-1500Vdc, kepha i-voltage yokuhlola ye-IEC 62133-2:2017 ukuhlolwa kokumelana nokufakwa ngu-500Vdc. Uma i-voltage ephezulu yesistimu yebhethri idlula i-500Vdc, iyiphi i-voltage yokuhlola okufanele isetshenziswe?

Ukuhlolwa kokumelana ne-insulation kusasebenzisa i-IEC 62133-2:2017 5.2 ukuze kuhlolwe. Izintambo nokufakwa kufanele kube ngokwanele ukumelana ne-voltage ephezulu elindelekile futhi kuhlolwe ngokuya ngezidingo ze-IEC 60950-1:2005, 3.1 kanye no-3.2 (bheka i-IEC 63056: 2020 isigatshana 5.2).

Bheka umfanekiso ongezansi, lapho wenza ukuhlolwa kokumelana nokufakwa kwe-insulation, kunezindlela ezimbili zokuxhuma umhloli wokumelana nokufakwa. Uma idivayisi yokuhlola kanye nesampula yokuhlola kuxhunywe ochungechungeni, ama-voltage akho azobekwa phezulu, futhi okunye ukwahlukanisa kwesistimu yebhethri kungase kumelane nomthamo wokuhlola ongaphezu kobubanzi. Ingabe ukuhlolwa kochungechunge kufanele kwenziwe ngalesi sikhathi?

Ukuxhunywa kochungechunge okungadala i-voltage superposition akufanelekile. Isizathu salo mehluko ukuthi inhloso ye-IEC 63056:2020 ukukala "ukumelana nokufakwa kwe-insulation koxhumana nabo be-DC kanye namandla omqhubi wokuvikela wesistimu". Inhloso ye-IEC 62133-2:2017 ukukala “ukumelana nokufakwa phakathi kwetheminali evumayo yebhethri nendawo yensimbi eveziwe yangaphandle (ngaphandle kokuxhumana kukagesi). Njengamanje, lesi sinqumo siseyisinqumo sesikhashana futhi sizovunywa emhlanganweni weqembu le-CTL ngo-2024.(PDSH 2229)
