CIinjongo zesindululo:

Nge-25 kaJuni, 2021, iwebhusayithi esemthethweni ye-UL ikhuphe isindululo solungiso samva nje kumgangatho we-UL2054. Ukufunwa kwezimvo kuhlala kude kube nguJulayi 19, 2021. Oku kulandelayosyimiba emi-6 yezilungiso kwesi sindululo:

1. Ukufakwa kweemfuno eziqhelekileyo zokwakhiwa kweengcingo kunye neeterminals: ukufakwa kweengcingo kufuneka kuhlangabezane neemfuno ze-UL 758;
2. Izilungiso eziziintlobo ngeentlobo kumgangatho: ubukhulu becala isilungiso esingapelwanga kakuhle, uhlaziyo lwemigangatho ekhankanyiweyo;
3. Ukongezwa kweemfuno zovavanyo lokunamathelaness: uvavanyo lokusula ngamanzi kunye ne-organic solvents;
4. Ukwandiswa kweendlela zolawulo lwamacandelo kunye neesekethe ezinomsebenzi ofanayo wokukhusela kuvavanyo lokusebenza kombane: Ukuba zimbiniefanayoamacandeloor iisekethe ziyasebenzakunyeukukhusela ibhetri, xa uqwalasela impazamo enye, amacandelo amabini okanye iisekethe kufuneka zibe nempazamo ngexesha elinye.
5. Ukumakisha uvavanyo lonikezelo lwamandla olunyiniweyoasngokuzikhethela: ingaba uvavanyo lonikezelo lwamandla olulinganiselweyo kwiSahluko se-13 somgangatho owenziweyo luya kumiselwa ngokweemfuno zomenzi.
6. Ukuguqulwa kwegatya le-9.11-uvavanyo lwesekethe emfutshane yangaphandle: umgangatho wokuqala kukusebenzisa i-16AWG (1.3mm2) ucingo olungenanto lobhedu.; ingcebiso yolungiso:tyena ukuxhathisa yangaphandle yesekethe emfutshanekufuneke ku80±20mΩ ucingo olungenanto lobhedu.

Iimpembelelo yesindululo kuyilo lwebhetri:

Inqaku lesi-4 leisindululoinokuba nefuthe elikhulu kuyilo lwebhetri: xa ingcebiso yokuguqulwa kwimpazamo yamacandelo okhuseleko kunye neesekethe zamkelwe, xa ukhuseleko lwenziwa ngeesekethe ezimbini ezifanayo okanye amacandelo, esinye isixhobo sokhuselo kufuneka songezwe ngenxa yokuba.abokuqalakufuneka iphoswe. Umzekelo, kuvavanyo lwentlawulo engaphezulu, ukuba zimbiniefanayoIi-MOSFET ezisetyenziselwa ukhuseleko lomrhumo ogqithisileyo kufuneka zibeneziphene ngaphandle kolunye uyilo lokukhusela umrhumo ogqithisileyoukusebenza, ibhetri ilahlekelwa ukukhuselwa kwe-overcharge kwaye uvavanyo alukwazi ukugqithiswa.

Isishwankathelo, kucetyiswa ukuba abavelisi bathathe iindlela ezimbini ezahlukeneyo zokukhusela xa beyila ibhetri ukujongana notshintsho olunokwenzeka olulandelayo.
