Cizinhloso zesiphakamiso:

Ngomhla zingama-25 kuJuni 2021, iwebhusayithi esemthethweni ye-UL yakhipha isiphakamiso sakamuva sokuchitshiyelwa kuzinga le-UL2054. Ukucelwa kwemibono kuqhubeka kuze kube umhlaka-19 Julayi 2021. Okulandelayosyizinto eziyi-6 ezichitshiyelwe kulesi siphakamiso:

1. Ukufakwa kwezidingo ezijwayelekile zesakhiwo sezintambo namatheminali: ukufakwa kwezintambo kufanele kuhlangabezane nezidingo ze-UL 758;
2. Izichibiyelo ezixubile kuzinga: ikakhulukazi ukulungiswa kokungapeli kahle, ukubuyekezwa kwamazinga acashuniwe;
3. Ukwengezwa kwezidingo zokuhlola zokunamathelaness: ukuhlolwa kokusula ngamanzi nezincibilikisi eziphilayo;
4. Ukwenyuka kwezindlela zokuphatha zezingxenye namasekhethi anomsebenzi ofanayo wokuvikela ekuhlolweni kokusebenza kukagesi: Uma kubiliefanayoizingxenyeor izifunda ziyasebenzandawonyeukuvikela ibhethri, uma ucabangela iphutha elilodwa, izingxenye ezimbili noma amasekhethi adinga ukuba nephutha ngesikhathi esisodwa.
5. Imaka ukuhlolwa kokunikezwa kwamandla okulinganiselweasongakukhetha: ukuthi ingabe ukuhlolwa kokunikezwa kwamandla okulinganiselwe eSahlukweni 13 sezinga kuyenziwa kuzonqunywa ngokuya ngezidingo zomkhiqizi.
6. Ukuguqulwa kwesigatshana 9.11-ukuhlolwa kwesifunda esifushane sangaphandle: indinganiso yokuqala ukusebenzisa i-16AWG (1.3mm2) i-copper Wire engenalutho; isiphakamiso sokushintsha:tyena ukumelana kwangaphandle wesifunda esifushanekufanele kube80±20mΩ intambo yethusi engenalutho.

Iumthelela wesiphakamiso ekwakhiweni kwebhethri:

Isigaba sesi-4 se-isiphakamisoingase ibe nomthelela omkhulu ekwakhiweni kwebhethri: uma isiphakamiso sokulungiswa kwephutha lezingxenye zokuvikela namasekhethi sesamukelwe, lapho ukuvikelwa kwenziwa ngamasekhethi amabili afanayo noma izingxenye, enye idivayisi yokuvikela idinga ukwengezwa ngobaezakuqalakudingeka kube nephutha. Isibonelo, ekuhlolweni kwe-overcharge, uma kubiliokufanayoAma-MOSFET asetshenziselwa ukuvikela ukukhokhiswa ngokweqile adinga ukuba nephutha ngaphandle kweminye imiklamo yokuvikela ukukhokhiswa ngokweqileukusebenza, ibhethri ilahlekelwa ukuvikelwa kokukhokhiswa ngokweqile futhi ukuhlolwa akunakwenzeka ukudlula.

Kafushane, kunconywa ukuthi abakhiqizi basebenzise izindlela ezimbili zokuvikela ezihlukene lapho beklama ibhethri ukuze babhekane nezinguquko ezingase zibe khona.
