Txheej txheem cej luam:

UL 2054 Ed.3 tau tshaj tawm thaum Lub Kaum Ib Hlis 17, 2021. Raws li tus tswv cuab ntawm UL tus qauv, MCM tau koom nrog kev tshuaj xyuas tus qauv, thiab tau muab cov lus qhia tsim nyog rau kev hloov kho uas tau txais yuav tom qab ntawd.

Cov ntsiab lus kho dua:

Cov kev hloov pauv tau ua rau cov qauv yog feem ntau koom nrog tsib yam, uas yog paraphrased raws li hauv qab no:

• Ntxiv ntawm ntu 6.3: Cov kev cai dav dav rau cov qauv ntawm cov xov hlau thiab cov terminals:

l Cov hlau yuav tsum tau rwb thaiv tsev, thiab yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm UL 758 thaum txiav txim siab seb qhov kub thiab qhov hluav taws xob tau ntsib hauv lub pob roj teeb puas tau.

l Cov taub hau thiab cov terminals yuav tsum tau muab kho dua tshiab, thiab kev sib cuag hluav taws xob yuav tsum tau muab, thiab yuav tsum tsis txhob muaj qhov nro ntawm cov kev sib txuas thiab cov terminals.Cov hlau lead yuav tsum muaj kev nyab xeeb, thiab khaws cia kom deb ntawm cov npoo ntse thiab lwm qhov chaw uas yuav ua rau cov hlau insulator.

• Lwm yam kev hloov kho yog ua thoob plaws hauv Tus Qauv;Nqe 2 - 5, 6.1.2 - 6.1.4, 6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, Nqe 23 lub npe, 24.1, Cov ntawv ntxiv A.
• Kev piav qhia ntawm qhov yuav tsum tau ua rau cov ntawv nplaum;Nqe 29, 30.1, 30.2
• Ntxiv rau qhov yuav tsum tau ua thiab cov txheej txheem ntawm Mark Durability Test
• Ua Txwv Lub Hwj Chim Qhov Chaw Ntsuas qhov kev xaiv tau;7.1
• Tshaj tawm qhov kev tawm tsam sab nraud hauv kev sim hauv 11.11.

Qhov Kev Ntsuas Hluav Taws Xob luv luv tau hais kom siv tooj liab xaim rau luv luv Circuit Court zoo thiab tsis zoo anodes ntawm ntu 9.11 ntawm tus qauv qub, tam sim no tau hloov kho raws li siv 80 ± 20mΩ sab nraud resistors.

Daim Ntawv Ceeb Toom Tshwj Xeeb:

Cov lus qhia: T_max+T_amb+T_ma tau ua pov thawj tsis raug nyob rau hauv nqe lus 16.8 thiab 17.8 ntawm tus qauv, thaum qhov kev qhia tseeb yuav tsum yog T_max+T_amb-T_mav,hais txog tus qauv qub.
