Muchidimbu:

UL 2054 Ed.3 yakaburitswa muna Mbudzi 17, 2021. Senhengo yechiyero cheUL, MCM yakapinda mukuwongorora chiyero, uye ikapa mazano ane musoro echigadziriso chakazogamuchirwa mushure.

Yakadzokororwa Content:

Shanduko dzakaitwa kune zviyero zvinonyanya kubatanidzwa nezvikamu zvishanu, izvo zvinotsanangurwa sezvinotevera:

• Kuwedzera kwechikamu 6.3: General zvinodiwa pakuumbwa kwewaya uye materminal:

l Waya inofanirwa kuiswa insulation, uye inofanirwa kusangana nezvinodiwa zve UL 758 uchifunga kana tembiricha inogona kuitika uye voltage yakasangana mubhatiri pack inogamuchirwa.

l Misoro yemawaya uye materminals anofanirwa kusimbiswa nemichina, uye kubata kwemagetsi kunofanirwa kupihwa, uye hapafanirwe kuve nekunetsana pane zvinongedzo uye materminal. Mutobvu unofanirwa kuve wakachengeteka, uye uchengetedzwe kure nekumucheto kwakapinza uye zvimwe zvikamu zvinogona kukuvadza waya insulator.

• Kudzokororwa kwakasiyana kunoitwa muChimiro chose; Zvikamu 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, Chikamu 23 musoro, 24.1, Appendix A.
• Kujekeswa kwezvinodiwa kune zvinyorwa zvekunamatira; Chikamu 29, 30.1, 30.2
• kuwedzera kwezvinodiwa uye nzira dzeMark Durability Test
• Made Limited Power Source Test chinhu chinodiwa; 7.1
• Yakajekesa kuramba kwekunze muyedzo muna 11.11.

Iyo Short Circuit Test yakarongedzerwa kushandisa waya yemhangura kupfupi dunhu rakanaka uye risingafadzi anode pachikamu 9.11 cheyekutanga chiyero, ikozvino chakadzokororwa sekushandisa 80 ± 20mΩ ekunze resistors.

Special Notice:

Izwi rokuti: T_max+T_amb+T_ma yakaratidzwa zvisizvo muchikamu 16.8 uye 17.8 chechiyero, nepo kutaura chaiko kuchifanira kuva T._max+T_amb-T_ma,tichireva chiyero chepakutanga.
