-Ukubuka Okujulile Kwekhebula Le-UL11627: Inketho Ethandwayo Yokuxhumanisa Isitoreji Samandla Kagesi{2}}I-Voltage Energy Storage - Ibhulogi

Ukuthuthukiswa okusheshayo kwezinhlelo zokugcina amandla (ESS), ama-photovoltaic inverters kanye nemishini yamandla avuselelekayo kwenza isilinganiso se-voltage, ukumelana nokushisa nokuphepha kwezintambo zangaphakathi kubalulekile ekusebenzeni kwesistimu ezinzile. I-UL11627 iyikhebula le-elekthronikhi elivalekile le-PVC. Ihambisana ne-UL 758 AWM. Ivamise ukusetshenziselwa izinto ezifana nokuxhunywa kwebhethri nezintambo ezishintshashintshayo zangaphakathi ngoba ikwazi ukuphatha amazinga okushisa afika ku-105 degrees Celsius kanye nama-voltage afika ku-2000 volts.

I-UL11627 iwela ngaphansi kwe-AWM Style 11627 yezinga le-UL 758, ngokuhlolwa okufanelekile okwenziwa ngokuya nge-UL 1581. Amapharamitha ayo abalulekile ami kanje:

I-Voltage elinganiselwe: 2000V AC / 2000V DC
Izinga lokushisa elilinganiselwe: 105 degree
I-Conductor: I-Single-core solid or stranded; ithusi elingenalutho noma ithusi elifakwe ethini
I-Insulation Material: I-PVC (i-Polyvinyl Chloride); itholakala ngemibala ehlukahlukene; ukushuba kwe-insulation efanayo; kulula ukuhlubula nokusika
I-Flame Retardancy: Iphumelele i-UL VW-1 ne-CSA FT1 ukuhlolwa kwelangabi eliqondile
Ukuthobela Imvelo: Ihambisana ne-RoHS nezinye izidingo
I-Gonga Radius: Ivamise ukuzungeza izikhathi eziyisi-6 ubukhulu bekhebula ukuze kufakwe okugxilile

Imvamisa ukwakhiwa kuyi-conductor eboshiwe efakwe ungqimba lwe-PVC olwengeziwe. Ubukhulu bokufakwa kwe-insulation kumageji amancane (isb. 18-26 i-AWG) cishe bungu-0.76 mm, futhi bukhuphuka ngokufanele kumagaraji amakhulu. Ukumelana ne-conductor kuhambisana nokucaciswa okusebenzayo kwe-AWG. (Ukumelana okuphezulu kwe-24 AWG cishe ku-94.2 Ω/km (ku-20℃) futhi ku-10 AWG cishe ku-3.5 Ω/km. Lezi zicaciso zenza intambo ifaneleke ngokukhethekile izinhlelo zokusebenza zokuxhuma kwangaphakathi lapho i-voltage ephezulu, umthamo wamanje ophakathi ukuya phezulu kanye nokuguquguquka okudingekayo.
Izinzuzo zomkhiqizo obalulekile ukuqina kokufakwa kwe-insulation, ukukhumula kalula, ukumelana nowoyela, i-oxidation namakhemikhali, ukuguquguquka okuphezulu komzila ezindaweni eziqinile kanye nesitifiketi esigcwele okwenza ukuthunyelwa emakethe yaseNyakatho Melika kube nomoya oshisayo noma ukuhlangabezana nezidingo zamakhasimende zokuthola isitifiketi se-UL.

Izindawo ezivelele kakhulu zokufaka izicelo ze-UL11627 yi-Energy Storage Systems (ESS) kanye nemishini ye-photovoltaic (PV). Ivamise ukusetshenziselwa ukuxhumana kwangaphakathi ngaphakathi kwamaphakethe ebhethri, ukuxhumana phakathi kwamabhethri namabhokisi esihlanganisi noma i-PCS (Amasistimu Okuguqula Amandla), kanye -nokufaka izintambo zangaphakathi zamanje eziphezulu kuma-inverter nama-conditioner kagesi.
Isifundo 1:Indawo yokuhlala kanye ne-C&I Energy Storage Battery Interconnection
Ekhabetheni elivamile le-lithium-yokulondoloza amandla e-ion, ukuxhumana phakathi kwamamojula ebhethri nokusuka kumamojula kuya kubha yebhasi eyinhloko kufanele kumelane nama-voltage aphezulu esistimu (ngokuvamile abe ngaphezu kuka-1000V, namanye amasistimu adizayinelwe u-1500V noma ngaphezulu). I-UL11627 (isb. 6Izicaciso ze-AWG noma ze-4AWG) iqinisekisa ukusebenza okuzinzile kwesikhathi eside ku-105℃, futhi ukufakwa kwe-PVC kunikeza ukuhlukaniswa okwanele kagesi kanye nokuvikelwa kokusebenza. Ngenxa yokuguquguquka kwayo, ingakwazi ukuzivumelanisa nesikhala esimpintshayo kanye nokudlidliza{10}}imvelo ecebile yamakhabethe amabhethri, inciphise ubunzima bokufakwa kanye nengozi yokwehluleka. Abahlinzeki abaningi bezintambo zezintambo zokugcina amandla batusa i-UL11627 njengohlobo lwekhebula lezinhlelo zokusebenza zokugcina amandla.
Isifundo 2:Izintambo zangaphakathi zama-PV Inverters nama-Power Conditioners
Amashidi amaningi edatha yomkhiqizo avela kubakhiqizi abafana ne-Sumitomo (Japan) abonisa ukuthi i-UL11627 ifanele{1}izinhlelo zokusebenza zamanje zezintambo zangaphakathi eziphezulu zama-inverter e-DC/AC nama-conditioner kagesi adinga izilinganiso zikagesi ophezulu. Kumaphrojekthi wangempela, ithusi eliboshwe ngethayelaIkhebula le-UL11627isetshenziswa phakathi kwamabhasi angaphakathi namamojula wamandla, ahlangabezana nemfuneko ye-voltage ye-2000V ye-voltage, ephase ukuhlolwa kwe-VW-1 flame retardancy, futhi ngenxa yalokho kwandisa amathuba okuba okokusebenza kudlule isitifiketi sokuphepha. Inganciphisa ngempumelelo ingcuphe yezingozi ezivela ekuqhekekeni kwamandla kagesi noma ukushisa ngokweqile ngamakhebuli avamile aphansi.
Isifundo 3:Izinqwaba zokushaja ze-EV kanye Nezisetshenziswa Ezintsha Zamandla
Amanye amamojula wamandla wokushaja izinqwaba kanye nezinto ezintsha zamandla kagesi aphinde asebenzise i-UL11627 ekuxhumekeni kwangaphakathi{1}}kwamavoltage aphezulu. Isilinganiso sayo esingu-2000V nokumelana nezinga lokushisa kunika amandla{4}ukudluliswa kwamandla okuphephile{4}ngaphakathi kwezindawo ezivalekile ezihlangene, kuyilapho kusiza ukucutshungulwa kwezintambo zezintambo kanye nokukhiqizwa okukhulu.
Ukwengeza, isetshenziswa kakhulu ekuxhumekeni kwangaphakathi ezintweni ezijwayelekile zikagesi nezikagesi, ikakhulukazi ezinhlelweni ezidinga izilinganiso zamandla kagesi aphezulu.

Amaphuzu abalulekile okuhlaziya okuqhathanisayo:

Isilinganiso samandla kagesi:I-UL11627 ihola kakhulu ngesilinganiso esingu-2000V, okuyenza ilungele amasistimu anama-voltage aphezulu okusebenza noma lawo adinga amamajini okuphepha amakhulu.I-UL10269yakhelwe ngokukhethekile ukugcinwa kwamandla; isilinganiso sayo esingu-1250V DC sifaka izicelo eziningi ze-BESS yaseNyakatho Melika futhi sithobelana nemibandela efanelekile ye-NEC. I-UL3271, ekalwe ku-600V, ifaneleka kangcono imishini yendabuko yezimboni.
Izinga lokushisa nezinto ezibonakalayo: I-insulation ye-XLPE esetshenziswa kuI-UL3271Imelana namazinga okushisa afika ku-125℃futhi inikeza ukumelana okuphakeme ekugugeni okushisayo namafutha uma kuqhathaniswa ne-PVC evamile, okuyenza ifanelekele{1}izindawo{2}}zezinga lokushisa eliphezulu{2}}eziphezulu noma izimo ezihlanganisa imithwalo eshisayo eqhubekayo. Nakuba i-PVC esetshenziswa ku-UL11627 naku-UL10269 isebenza ngokuthembekile ku-105 degree, i-XLPE ibamba inzuzo ehlukile ngaphansi{7}}izimo zezinga lokushisa ezinde.
Isikhundla sohlelo lokusebenza:I-UL10269 iyisixazululo "sokugcina amandla esizinikezele" esilungiselelwe ukuxhumana kwe-DC njengamamojula ebhethri namabhasi.I-UL11627inketho eguquguqukayo efanelekayo-izintambo ze-voltage zangaphakathi eziphezulu. I-UL3271 iyifanele kakhulu impahla yezimboni noma yokuphakela ugesi edinga izilinganiso zokushisa eziphakeme.

Lapho ukhetha ikhebula, cabangela lokhu okulandelayo: uma iphrojekthi iqondise emakethe yaseNyakatho Melika futhi isebenzisa amakhabethe e-ESS ajwayelekile, i-UL10269 ingase ihambisane kangcono nezidingo zesitifiketi; uma i-margin ephakeme kagesi noma ukuguquguquka okukhulu okudingekayo, i-UL11627 inikeza izinzuzo; futhi uma isebenza-ezindaweni ezizungezile{3}}zezinga lokushisa eliphezulu, i-UL3271 kufanele kube inketho ekhethwayo.

①I-Voltage yesistimu: Beka kuqala i-UL11627 lapho i-voltage yesistimu isondela noma idlula i-1000V; cabanga nge-UL10269 yezinhlelo zokusebenza ezijwayelekile zesitoreji samandla esingu-1250V DC.
②Izinga lokushisa kanye nemvelo: I-XLPE-i-insulated UL3271 iyinketho ephephile ezindaweni ezinamazinga okushisa aphezulu ekhabhinethi noma ukuchayeka kuwoyela/ugrisi.
③I-Conductor nokuvumelana nezimo: Khetha i-AWG ephansi (igeji ewugqinsi) yezinhlelo zokusebenza eziphakeme{{0}zamanje; ithusi elihlanganisiwe linikeza ibhalansi ye-conductivity kanye nokumelana ne-oxidation.
④Ukuqinisekiswa Kwesitifiketi: Qinisekisa ukuthi umphakeli uhlinzeka ngesitifiketi se-UL esivumelekile futhi uhlangabezana namazinga emvelo afana ne-RoHS.
⑤Izinyathelo zokuphepha zokufaka: Namathela ezidingweni zerediyasi egobayo encane (imvamisa izikhathi ezi-4–6 kunobubanzi obungaphandle) futhi ugweme ukulimala kokufakwayo okubangelwa imiphetho ebukhali noma amakhona.

Ngesilinganiso sayo samandla kagesi aphezulu angu-2000V, ukumelana nezinga lokushisa elingu-105 degree, nokuguquguquka okuhle kakhulu kokucubungula,I-UL11627inketho ethembekile{0}yekuxhumo lwebhethri lamandla kagesi aphezulu kanye nezintambo zangaphakathi kuma-inverter e-photovoltaic. Ukuqhathanisa neI-UL10269(eklanyelwe ngokukhethekile ukugcinwa kwamandla) kanye ne-UL3271 ({1}}izinga lokushisa eliphezulu i-XLPE) iveza ukuthi ngayinye inamandla ayo: I-UL11627 inikeza i-high voltage margin, i-UL10269 iqondana kangcono namazinga e-North American ESS, futhi i-UL3271 ihamba phambili{5}}ezimweni zokushisa eziphezulu.
