UMBUZO: Yintoni abaFumaneka abaSebenzisi ngayo phambi kokutshintsha ilothe{0}}Iibhetri ze-Acid ngeLithium?
A: Qinisekisa ukuba isixokelelwano esikhoyo siyakwazi ukuxhasa iprofayili yevoltage yentlawulo yebhetri ye-lithium. Iiseli ze-LiFePO4 zine-curve yentlawulo eyahlukileyo kune-VRLA, kwaye abanye abahlaziyi abadala banokungahambelani ngaphandle kohlaziyo lwe-firmware okanye imodyuli yetshaja ye-lithium ezinikeleyo. Kwakhona qinisekisa ukuba iprotocol yonxibelelwano ye-BMS (i-SNMP, i-Modbus, i-CAN ibhasi) iyahambelana nomlawuli wesayithi, kwaye i-DC ekhoyo i-breakers yesekethe ireyithwe kwi-fault current yebhanki entsha.
Umbuzo: Ngaba i-Telecom BESS inokudityaniswa neePaneli zeSolar kunye neeJenereyitha?
A: Ewe. ISolar-ibhetri{2}}iisixokelelwano zejenereyitha ezixutyiweyo ziya zisiba semgangathweni wokucinywa-kwegridi kunye neendawo ezibuthathaka{4}}zegridi yetelecom. I-BESS igcina amandla elanga emini, inikezela ngomthwalo ebusuku, kwaye ilungelelanisa ne-auto yejenereyitha{6}}ingqiqo yokuqala ukugcina amandla ngexesha elongeziweyo elisezantsi{7}}lokukhanya kwelanga. Ukudityaniswa okufanelekileyo kufuna ukuhambelana nesiphumo somlawuli welanga kwixabiso leeparamitha zentlawulo yebhetri kunye nokucwangcisa i-generator start/stop thresholds ngokusekelwe kwibhetri ye-SoC.
Umbuzo: Yeyiphi iMigangatho yoShishino eSebenzayo kwiiNkqubo zaMandla ezigciniweyo zeTelecom?
A: Imigangatho engundoqo iquka i-ETSI EN 300 132-2 (−48 V DC ujongano lwamandla ezixhobo ze-ICT), i-ITU -T L.1200 series (DC feeding power for telecom), ITU{4}}T L.1397 (ujongano nolawulo lweenkqubo zebhetri), kunye NEBS (Network Equipment{6}}Ulwakhiwo lokusingqongileyo kunye nokubanjwa kweSistim. Ukhuseleko lwebhetri lusenokuwela phantsi kwe-IEC 62619 (iimfuno zokhuseleko kwiiseli ze-lithium zesibini kwizicelo zoshishino) kunye ne-UL 1973 (iibhetri zezicelo ezimileyo).
Ukuqukumbela
Inkqubo yogcino lwebhetri yetelecom ayilogcino nje - sisiseko sokufumaneka kwenethiwekhi. Umnxeba ngamnye oyehliweyo, iseshoni yedatha engaphumelelanga, kunye nokuhanjiswa kwexesha likaxakeka ngexesha lokucima kombane kubonisa iindleko ezithe ngqo kumsebenzisi kunye noluntu oluxhomekeke kuqhagamshelwano.
Ukukhetha isixokelelwano esilungileyo kuthetha ukungqamanisa ubume bebhetri, umthamo, ulawulo lobushushu, kunye nokubeka iliso kumthwalo okhethekileyo wendawo nganye, iimfuno zokuzimela, iimeko zokusingqongileyo, kunye{0}}nobuchule bokusebenza bexesha elide. Ifomula yokulinganisa, -itheyibhile yohlobo lwesigqibo, kunye nokuhlolwa kokudityaniswa okuchazwe kwesi sikhokelo kubonelela ngesiqalo esisebenzayo kubasebenzisi be-telecom, amaqela okuthenga, kunye neenjineli zeprojekthi ezivavanya ukusasazwa kwabo okulandelayo kwe-BESS.
Ngaphambi kokuba uchaze inkqubo, yenza umlinganiselo wemithwalo yesayithi yakho, chaza iithagethi zakho zokuzimela, uvavanye imiqobo yakho yokusingqongileyo, kwaye ubale iindleko zizonke zobunini kubomi benkonzo obulindelekileyo obupheleleyo. Ngoyilo olufanelekileyo, i-telecom BESS iyanciphisa ixesha lokuphumla, inciphisa iindleko zokusebenza, kwaye ixhasa ukufumaneka kwenethiwekhi efunwa ngababhalisi kunye nabalawuli.
