Ezweni lanamuhla ledijithali elisheshayo, kubalulekile ukuqinisekisa ukuthi amasistimu akho abalulekile ahlala esebenza ngesikhathi sokucima kukagesi. Kumabhizinisi nezikhungo zedatha, izixazululo ezithembekile zokulondoloza amandla zibalulekile.Izipele zebhethri le-lithium ezifakwe kwi-rackziyizinqumo ezidumile ngenxa yokusebenza kahle kwazo okuphezulu, ukwakheka okuhlangene, nempilo ende. Kodwa-ke, ukunquma usayizi olungile wesipele sebhethri ye-lithium efakwe ku-rack kungaba umsebenzi onzima. Lesi sihloko sizokuqondisa ekucabangeni okudingekayo kanye nezibalo ukuze uthole umkhiqizo ohambisana nezidingo zakho.
Funda mayelana ne-rack mount ibhethri ye-lithium
Ngaphambi kokuthi singene kubukhulu, kubalulekile ukuqonda ukuthi iyini ibhethri ye-lithium efakwe kwi-rack. Lawa masistimu aklanyelwe ukuhlinzeka ngogesi ongaphazamiseki (i-UPS) kumishini ebalulekile kuma-server racks. Ngokungafani namabhethri endabuko e-lead-acid, amabhethri e-lithium anikeza izinzuzo ezimbalwa, okuhlanganisa:
1. Impilo ende yesevisi: Impilo yesevisi yamabhethri e-lithium ingafinyelela iminyaka eyi-10 noma ngaphezulu, okuyinde kakhulu kunaleyo yamabhethri e-lead-acid.
2. I-Higher Energy Density: Iletha amandla engeziwe endaweni encane, okuyenza ilungele izinhlelo zokusebenza zokukhweza i-rack.
3. Ishaja Ngokushesha: Amabhethri e-lithium ashaja ngokushesha, aqinisekisa ukuthi isistimu yakho isilungile ngesikhathi esincane.
4. Isisindo Esilula: Isisindo esincishisiwe senza ukufakwa nokugcinwa kube lula.
Ukucatshangelwa okubalulekile kokulinganisa
Lapho ulinganisa ibhethri ye-lithium eyisipele efakwe kwi-rack, kunezici ezimbalwa okufanele uzicabangele:
1. Izidingo zamandla
Isinyathelo sokuqala ukuhlola izidingo zamandla zedivayisi ofuna ukulenza ikhophi yasenqolobaneni. Lokhu kuhilela ukubala isamba samanzi sawo wonke amadivayisi azoxhunywa ebhethrini eliyisipele. Ungathola lolu lwazi ngezicaciso zedivayisi noma ngokusebenzisa i-wattmeter.
2. Izidingo zesikhathi sokusebenza
Okulandelayo, cabanga ukuthi ama-backups adinga ukuhlala isikhathi eside kangakanani phakathi nokucisha. Lokhu kuvame ukubizwa ngokuthi “isikhathi sokusebenza”. Isibonelo, uma udinga ukugcina isistimu isebenza imizuzu engama-30 phakathi nokuphela kukagesi, udinga ukubala isamba samahora wama-watt adingekayo.
3. Ukusebenza kahle kwe-inverter
Khumbula, isiguquli siguqula amandla e-DC ukusuka kubhethri kuya kumandla we-AC kusuka kudivayisi, ngesilinganiso esisebenza kahle. Ngokuvamile, lolu hlu luyi-85% kuya ku-95%. Lokhu kufanele kufakwe ezibalweni zakho ukuqinisekisa ukuthi unomthamo owanele.
4. Ukwandiswa kwesikhathi esizayo
Cabangela ukuthi uzodinga yini ukungeza izisetshenziswa eziningi ngokuzayo. Kuwukuhlakanipha ukukhetha ikhophi yasenqolobaneni yebhethri engavumela ukukhula okungase kube khona, okuvumela ukuthi kufakwe okokusebenza okwengeziwe ngaphandle kokushintsha isistimu yonke.
5. Izimo zemvelo
Indawo yokusebenza yebhethri nayo ithinta ukusebenza kwayo. Izinto ezifana nezinga lokushisa, umswakama, nomoya kufanele zicatshangelwe njengoba zithinta ukusebenza kahle kwebhethri nempilo yokuphila.
Bala usayizi ofanele
Ukuze ubale usayizi ofanele wokukhweza isipele ibhethri ye-lithium, landela lezi zinyathelo:
Isinyathelo 1: Bala amandla aphelele
Engeza amanzi awo wonke amadivayisi ohlela ukuwaxhuma. Isibonelo, uma une:
- Iseva A: 300 watts
- Iseva B: 400 watts
- Ukushintsha kwenethiwekhi: 100 watts
Ingqikithi yamandla = 300 + 400 + 100 = 800 watts.
Isinyathelo sesi-2: Thola isikhathi sokusebenza esidingekayo
Nquma ukuthi ufuna ukuthi izipele zakho zihlale isikhathi esingakanani. Kulesi sibonelo, cabanga ukuthi udinga imizuzu engama-30 yesikhathi sokusebenza.
Isinyathelo sesi-3: Bala amahora wama-watt adingekayo
Ukuze uthole inombolo edingekayo yamahora wama-watt, phinda isamba se-wattge ngesikhathi esidingekayo sokusebenza ngamahora. Njengoba imizuzu engama-30 amahora angu-0.5:
Amahora we-Watt = 800 Watts × amahora angu-0.5 = amahora angu-400 Watt.
Isinyathelo sesi-4: Lungisa ukusebenza kahle kwe-inverter
Uma i-inverter yakho isebenza kahle ngo-90%, udinga ukulungisa amahora we-watt ngokufanele:
Amahora we-watt alungisiwe = amahora angama-watt angama-400 / 0.90 = amahora angama-444.44 watt.
Isinyathelo sesi-5: Khetha ibhethri elilungile
Manje njengoba usunamahora we-watt owadingayo, ungakhetha ibhethri le-lithium elifakwe kwi-rack elihlangabezana noma elidlula lo mthamo. Abakhiqizi abaningi bahlinzeka ngezichasiselo ezihlanganisa isamba sehora le-watt-hora lesistimu yebhethri labo, okwenza kube lula ukuthola ukukhetha okulungile.
Ekuphetheni
Ukukhetha usayizi olungileibhethri ye-lithium efakwe kwi-rackkubalulekile ekuqinisekiseni ukwethembeka kwezinhlelo ezibucayi. Ngokuhlola ngokucophelela izidingo zakho zamandla, izidingo zesikhathi esengeziwe, nezinhlelo zokunweba zesikhathi esizayo, ungenza izinqumo ezinolwazi ukuze ugcine imisebenzi yakho isebenza kahle ngesikhathi sokucima. Ngezinzuzo zobuchwepheshe be-lithium, ukutshala imali ohlelweni oluyisipele lwebhethri akukwazi nje ukukhulisa ukuqina kwakho kokusebenza kodwa futhi kusize ukudala ikusasa lamandla elizinzile. Kungakhathaliseki ukuthi uphatha isikhungo sedatha noma ibhizinisi elincane, ukuqonda izidingo zakho zamandla kuyisinyathelo sokuqala sokuqinisekisa ukuthi imisebenzi yakho ivikelekile ekuphazamisekeni okungalindelekile.
