Posachedwapa International Electrotechnical Commission EE yavomereza, kutulutsa ndi kuletsa zisankho zingapo za CTL pamabatire, zomwe makamaka zimakhudza kunyamula batire muyezo IEC 62133-2, mphamvu batire satifiketi yosungira mphamvu IEC 62619 ndi IEC 63056.

IEC 62133: 2017, IEC 62133: 2017 +AMD1:2021: kuletsa batire 60Vdc malire voteji chofunika

Mu Disembala 2022, CTL idapereka chigamulo chakuti ma voliyumu azinthu za batire sangapitirire 60Vdc. Palibe mawu omveka bwino okhudza malire amagetsi mu IEC 62133-2, koma amatanthauza muyezo wa IEC 61960-3.

Chifukwa chomwe chigamulochi chinaletsedwera ndi CTL ndikuti "mphamvu yamagetsi yapamwamba ya 60Vdc idzaletsa zinthu zina zamakampani kuti zisayesedwe, monga zida zamagetsi, ndi zina zotero."

IEC 62133: 2017, IEC 62133: 2017 +AMD1:2021: kuletsa kufunikira kwa kutentha kwa kutentha

Momwemonso, mu chigamulo chokhazikika chomwe chinaperekedwa mu December chaka chatha, chinaperekedwa kuti pamalipiritsa pa njira ya Article 7.1.2 (yofuna kulipira malire a kutentha kwapamwamba ndi kutsika), ngakhale mu Zakumapeto A.4 za mulingo umanena. kuti pamene kutentha kwapamwamba/kutsika kwachapira sikuli 10 ℃/45 ℃, kutentha kwapamwamba kuyenera kukhala +5 ℃ ndipo kutsika kwapang’onopang’ono kumafunika -5℃. Komabe, pakuyesa kwenikweni, ntchito ya +/-5 ° C imatha kusiyidwa ndipo kulipiritsa kumatha kuchitidwa molingana ndi kutentha kwapamwamba / kutsika kwapang'onopang'ono.

Chigamulochi chinaperekedwa pa msonkhano wa CTL chaka chino.

IEC 62619: 2017: gwiritsani ntchito BMS yopangidwa ndi gulu lachitatu pakuwunika chitetezo pakugwira ntchito kwa batri

Kusamvana uku kukukhudza kuwunika kwa chitetezo cha machitidwe a batri a BMS.

Tsopano ambiri opanga mabatire amagula BMS kuchokera kwa anthu ena, zomwe zingapangitse kuti wopanga batire asathe kumvetsetsa kapangidwe kake ka BMS. Woyesayo akamayesa chitetezo pogwiritsa ntchito Annex H ya IEC 60730-1, wopanga sangapereke khodi ya BMS.

Pamenepa, woyesa akhoza kuyesa kachidindo kochokera padera ndi wopanga BMS kuti ateteze ufulu wake wazinthu zaluntha. Kuwunika kwachitetezo cha batri ndikofunikira, ndipo kuwunikako sikungaletsedwe chifukwa wopanga batire sangathe kupereka magwero.

Pakadali pano, chigamulochi chikadakhalabe kwakanthawi ndipo chidzavomerezedwa pa msonkhano wa CTL mu 2024.(PDSH 2230)

IEC 63056: 2020: voliyumu yoyesa kukana kwa insulation

IEC 63056: 2020 Ndime 7.4 (Kuyendera kwamagetsi pamayendedwe ndi kukhazikitsa) imatanthawuza IEC 62133:2017 poyesa kukana kukana. Ili ndi vuto pokonza. Zolembazo ziyenera kukhala IEC 62133-2:2017. Cholakwika ichi chadziwitsidwa ku IEC TC21A.

IEC 63056 muyezo akhoza kuphimba mankhwala ndi voteji pazipita 1500Vdc, koma voteji mayeso a IEC 62133-2:2017 kutchinjiriza kukana mayeso ndi 500Vdc. Ngati mphamvu yayikulu ya batire ipitilira 500Vdc, ndi magetsi ati omwe amayenera kugwiritsidwa ntchito?

Kuyesa kwa insulation resistance kumagwiritsabe ntchito IEC 62133-2: 2017 5.2 pakuwunika. Mawaya ndi kutchinjiriza ziyenera kukhala zokwanira kupirira mphamvu yamagetsi yomwe ikuyembekezeka ndikuwunikidwa molingana ndi zofunikira za IEC 60950-1:2005, 3.1 ndi 3.2 (onani IEC 63056: 2020 clause 5.2).

Onani chithunzi chomwe chili pansipa, poyesa kukana kukana, pali njira ziwiri zolumikizira tester insulation resistance. Pamene chipangizo choyesera ndi chitsanzo choyesera chikugwirizanitsidwa motsatizana, ma voltages awo adzakhala apamwamba kwambiri, ndipo kusungunula kwina kwa batri kumatha kupirira voteji yoyesera kupitirira malire. Kodi kuyesa kwa mndandanda kukuyenera kuchitika panthawiyi?

Maulumikizidwe a Series omwe angapangitse kuti voteji superposition ikhale yosayenera. Chifukwa cha kusiyana kumeneku ndikuti cholinga cha IEC 63056: 2020 ndikuyesa "kukana kwa insulation kwa ma contacts a DC ndi mphamvu zoteteza makina". Cholinga cha IEC 62133-2: 2017 ndikuyezera "kukana kwachitetezo pakati pa batire yabwino ya batire ndi zitsulo zowonekera kunja (kupatula kukhudzana ndi magetsi). Pakadali pano, lingaliro ili likadali losakhalitsa ndipo livomerezedwa pamsonkhano wapagulu wa CTL mu 2024.(PDSH 2229)
