Pa Juni 28^th2023, muyezo wamabatire osungira mphamvuANSI/CAN/UL 9540:2023:Muyezo wa Mphamvu Zosungirako Mphamvu ndi Zida ikupereka kukonzanso kwachitatu.Tidzasanthula kusiyana kwa tanthauzo, kapangidwe ndi kuyesa.

Mafotokozedwe owonjezera

• Onjezani tanthauzo la AC ESS
• Onjezani tanthauzo la DC ESS
• Onjezani tanthauzo la Dwelling Unit
• Onjezani tanthauzo la Energy Storage Management System (ESMS)
• Onjezani tanthauzo la External Warning Communication System (EWCS)
• Onjezani tanthauzo la Flywheel
• Onjezani tanthauzo la Malo Okhazikika
• Onjezani tanthauzo la Kusintha kwa Mapulogalamu Akutali

Chofunikira Chatsopano pamapangidwe

• Pa Battery Energy Storage System (BESS), mpanda uyenera kukumana ndi mayeso a UL 9540A Unit Level.
• Gasket ndi zisindikizo zimatha kutsatira UL 50E/CSA C22.2 No. 94.2 kapena kutsatira UL 157 kapena ASTM D412
• Ngati BESS imagwiritsa ntchito mpanda wazitsulo, mpandawo uyenera kukhala zinthu zosapsa kapena zigwirizane ndi UL 9540A unit.
• Kutsekera kwa ESS kuyenera kukhala ndi mphamvu komanso kukhazikika.Izi zitha kutsimikiziridwa ndikupambana mayeso a UL 50, UL 1741, IEC 62477-1, UL 2755, ISO 1496-1 kapena milingo ina.Koma kwa ESS yochepera 50kWh, kulimba kwa mpanda kungawunikidwe kudzera mu muyezo uwu.
• Yendani mkati mwa ESS yotetezedwa ndi kuphulika ndi kutulutsa mpweya.
• Mapulogalamu omwe atha kukwezedwa patali ayenera kutsatira UL 1998 kapena UL60730-1/CSA E60730-1 (mapulogalamu a Gulu B)
• ESS yokhala ndi mabatire a lithiamu-ion mphamvu ya 500 kWh kapena kupitilira apo iyenera kuperekedwa ndi njira yolumikizirana yochenjeza (EWCS) kuti idziwitse ogwiritsa ntchito za vuto lomwe lingachitike pachitetezo.
• Kuyika kwa EWCS kuyenera kuloza NFPA 72. Alamu yowonekera iyenera kukhala yogwirizana ndi UL 1638. Alamu yamawu iyenera kukhala yogwirizana ndi UL 464/ ULC525.Mulingo wapamwamba wamawu wama alamu omvera suyenera kupitilira 100 Dba.
• ESS yokhala ndi zamadzimadzi, kuphatikiza ESS yokhala ndi zoziziritsa zomwe zimakhala ndi zoziziritsa zamadzimadzi, ziyenera kupatsidwa njira zina zodziwira kuti zatsitsidwa kuti ziwone kutayika kwa choziziritsa.Kutulutsa koziziritsa komwe kwazindikirika kumapangitsa kuti pakhale chizindikiro chochenjeza ku ESS yowunikira ndi kuwongolera dongosolo ndipo adzayambitsa alamu ngati aperekedwa.
• Phokoso la phokoso lochokera ku ESS panthawi yogwira ntchito liyenera kukhala la maola a 8 olemetsa nthawi ya 85 Dba.Itha kuyesedwa kudzera mu 29 CFR 1910.95 kapena njira yofananira.Dongosolo lomwe lili ndi maphokoso opitilira malire awa liyenera kupatsidwa zilembo zochenjeza ndi malangizo.(Izi zikupitirirabe malire a EU machinery Directive, yomwe ndi 80 Dba)
• Electrochemical ESS yokhala ndi malo ophatikizika pomwe pali kuthekera kwa mpweya woyaka moto mkati mwa malo otsekeredwa kuchokera kuzinthu zosazolowereka monga kuthawa kwamafuta ndi kufalikira, zidzaperekedwa ndi deflagration kapena kuphulika kotetezedwa molingana ndi NFPA 68 kapena NFPA 69. Chitetezo sichili chofunika ngati kuyezetsa molingana ndi UL 9540A ndi kuwunika kwa ngozi ya deflagration kukuwonetsa kuti kuchuluka kwa mpweya woyaka woyezedwa pakuyesedwa kumakhalabe pansi pa 25 % LFL.Kwa ESS makabati / enclosures, chitetezo china kuposa momwe taonera chingagwiritsidwe ntchito ngati zatsimikiziridwa kuti ESS cabinet / enclosure yapangidwa kuti itetezere bwino ku zoopsa chifukwa cha zowonongeka zoyaka pamene ESS yayesedwa molingana ndi Unit Level kapena Kuyesa kwa Level UL 9540A.
• ESS yokhala ndi zolimba zowopsa (ie pyrophoric kapena zitsulo zotulutsa madzi) zidzapangidwa ndikukhazikitsidwa molingana ndi NFPA 484.

Zinthu zatsopano zoyesedwa

Lakage mayeso

Kwa ESS pogwiritsira ntchito zoziziritsa kukhosi zamadzimadzi kapena zokhala ndi madzi owopsa, madzimadzi opitilira 1.5 (ngati akuyezetsa ndi madzi) mphamvu yayikulu yogwiritsira ntchito kapena kuwirikiza ka 1.1 mphamvu yogwira ntchito kwambiri (ngati kuyezetsa mpweya wa mpweya) iyenera kuyikidwa pazigawo zomwe zili ndi madzimadzi.Sipadzakhala kutayikira kwa zigawozo.

1.Ekutsekeka zotsatira

Ponyani chitsulo chozungulira ndi 50.8 mm m'mimba mwake ndi kulemera kwa 535 g kuchokera kutalika kwa 1.29 m pamwamba pa chitsanzo.

Imitsani chitsulo chozungulira ndi chingwe ndikugwedezeka ngati pendulum, ndikutsika pamtunda wa 1.29m kuti mukhudze nkhope zam'mbali.

Pambuyo pa zovutazo, DUT idzayesedwa ndi Dielectric Voltage Withstand Test.DUT idzawunikiridwa ngati pali zizindikiro zosweka kapena zowonongeka.Sipadzakhala kuwonongeka kwa mpanda komwe kungayambitse ngozi monga kuwonetseredwa kwa mbali zowopsa kapena kuwonongeka kwa dielectric.

2.Mpanda wolimba mphamvu

Mayesowa amachitidwa pa electrochemical ESS yomwe ndi ya ntchito zogona kapena ntchito zosakhalamo zochepera kapena zofanana ndi 50 kWh.Chitsanzocho chiyenera kupirira mphamvu ya 250N ± 10N ndi chida choyesera chozungulira cha 30 mm m'mimba mwake.Kuyesedwa kuyenera kuchitidwa motsatana pamwamba, pansi ndi mbali za mpanda.DUT idzayesedwa ndi Dielectric Voltage Withstand Test.Sipadzakhala kuwonongeka kapena kuwonongeka kwa dielectric.

3.Kupsinjika kwa nkhungu

Chiyeso ichi ndi cha mpanda wopangidwa ndi polymeric.Ikani chitsanzo mu ng'anjo yosungidwa pa kutentha kwa yunifolomu osachepera 10 ℃ (18 ℉) kuposa kutentha kwakukulu kwa mpanda woyezedwa panthawi yogwira ntchito ndikusunga kwa maola 7.Pambuyo pochotsedwa mu uvuni, chitsanzocho chiyenera kuyesedwa ndi dielectric voltage standstand test.Pasakhale kusweka kwa mpanda kapena kuwonongeka kwa dielectric.

Chivomezi chilengedwe

Pali zida zomwe sizingawunikidwe mwa kuyesa kokha chifukwa cha kukula kwa zida.Pazifukwa izi, pangafunike kusanthula kophatikizana ndikuyesa magawo adongosolo.Njira iyi yafotokozedwa mu IEEE 344.

Zatsopano Zowonjezera ANNEX

Onjezani annex G - CLEAN AGENT DIRECT IJEKISI YA BATTERY RACK COOLANT SYSTEM UNITS

CLEAN AGEN - Chozimitsa moto chosagwiritsa ntchito magetsi, chosasunthika, kapena cha mpweya chomwe sichisiya zotsalira zikatuluka nthunzi.

DIRECT BATTERY RACK COOLANT SYSTEM UNIT - Zigawo zodziwika zomwe zimasonkhanitsidwa kuti zizitulutsa zoyera kudzera pa mapaipi osakhazikika ndi ma nozzles ndicholinga choziziritsa ma module a batri kuti achepetse kufalikira kwamafuta mkati mwa batire loyima / makina osungira mphamvu ya batri. .

Izi zitha kuganiziridwanso ngati njira yozimitsa moto ya ESS
