Phakathi kweentlobo ezahlukeneyo ze-UPS, eyona nto ixhaphake kakhulu kumagumbi omncedisi wokungena i-Smart UPS esuka kwi-APC (ngoku eyi-Schneider Electric). Ukuthembeka okugqwesileyo kunye nexabiso eliphantsi kwimarike yesibini negalelo kwinto yokuba abalawuli benkqubo, ngaphandle kokucinga okuninzi, bancamathele idatha ye-UPS kwiiracks kwaye bazame ukukhupha inzuzo ephezulu kwi-hardware yeminyaka eyi-10-15 ngokutshintsha nje iibhetri. Ngelishwa, oku akusoloko kunika umphumo olindelekileyo. Makhe sizame ukufumanisa ukuba yintoni kwaye wenze njani ukwenza i-UPS yakho isebenze "njengentsha".
Ukukhetha ibhetri
Onke amanqaku kunye nezihloko kwiiforum malunga nokukhetha ibhetri ye-UPS zihlala zifana nezihloko ekukhetheni i-oyile ye-injini yeemoto / iimoto. Masizame ukungafani nabo, kodwa ukuqonda imigaqo esisiseko yokukhetha iibhetri usebenzisa umzekelo womenzi we-CSB.
Siyabona ukuba banenqwaba yemigca yebhetri eyahlukeneyo: GP, GPL, HR, HRL, UPS, TPL.
Masiqale ukufunda: GP, GPL - iibhetri zokusetyenziswa jikelele kwimisinga yokukhupha ephantsi naphakathi. Kucetyiswa ukuba kusetyenziswe iinkqubo zokhuseleko kunye nomlilo kunye ne-UPS. Azisifanelanga. Nangona zihlala zithengwa ngaphandle kokuzikhathaza ngokufunda iimpawu zabo.
Uchungechunge lwe-HR - iibhetri ezinomthamo wamandla owandisiweyo kunye nokuvumela ukukhutshwa okunzulu (ukuya kwi-11% yomthamo oseleyo), luncedo ngakumbi xa kufuneka ukukhutshwa okuphezulu. Umahluko phakathi kweebhetri "H" uyilo olukhethekileyo lwegridi evumela ukwanda kwamandla ombane ngama-20%. Zezona zilungele ukusetyenziswa kwizityalo zamandla aphezulu kunye ne-UPS.
Ileta "L" kuluhlu lubonisa ukuba ezi ziibhetri ezinobomi obude benkonzo (uBomi obude) ekusebenzeni kwe-buffer ukuya kwiminyaka eyi-10.
Ewe, uchungechunge lwe-UPS yibhetri eyenzelwe ngokukodwa ukusebenza kwimowudi ephezulu yangoku kunye nexesha elifutshane lokukhupha.
Mna, ndakhetha ixesha elide phakathi kwe-UPS kunye ne-HRL, kodwa ndagqiba ekubeni ndithathe i-HRL. Ngelishwa, kuya kwenzeka ukuthetha malunga nendlela abaya kuziphatha ngayo emsebenzini wexesha elide kwiminyaka emi-5, kwaye i-necroposting ayibonakali iyamkeleka kakhulu. Ke ngoko, siya kucinga ukuba olu lukhetho lwam kwaye andizukuyinyanzela. Kodwa kufuneka uqonde ukuba kufuneka ukhethe iibhetri eziphezulu zangoku, kuba kufuneka zikwazi ukukhulula amandla abo aqokelelweyo kwimizuzu engama-20-30.
Ukukhethwa kokudibanisa ibhetri
Ukuqwalasela ukuba iibhetri ezininzi zisetyenziswa kwindibano, kunqweneleka kakhulu ukuba baneempawu ezifanayo. Ngenxa yokuba ibhetri enye ephantsi iya kukhokelela kwinto yokuba yonke indibano ayiyi kusebenza konke konke njengoko kulindelwe.
Malunga neminyaka emi-5 edlulileyo, ndafumanisa inkampani yaseRostov iBastion, evelisa abavavanyi bebhetri phantsi kophawu lweSkat. Andicingi ukuba ndibanga ukuchaneka okufanelekileyo kwemilinganiselo yomthamo, kodwa ukuvavanya inqanaba: i-ideal-ephila-uya-use-service-isidumbu, lo mvavanyi ungaphezulu kokwaneleyo.
Ngokomgaqo, unokulinganisa umthamo kunye ne-banal charge-discharge usebenzisa iwotshi, isibane semoto ye-21W (inika umthwalo omalunga ne-1A) kunye nomhloli, kodwa oku kudla ixesha kwaye kaninzi kunobuvila.
Ewe, njengecebo lokugqibela, sizama nje ukufaka iibhetri ezintsha kwibhetshi enye kwaye sinethemba lokuba unethamsanqa.
Umbane yinzululwazi yoqhagamshelwano
Olunye unxibelelwano olubi kwindibano yeebhetri ezi-4 luya kuzichasa zonke iinzame zakho, ngoko ke siyayichitha indibano ngononophelo olukhulu. Ngokuqhelekileyo, i-UPS isebenzisa iziqhagamshelo zebhetri ezineentambo, ezinokuthi zijikwe zibe yindawo efileyo ngokuzikhupha nje. Ke ngoko, sithatha i-screwdriver encinci esicaba, siyifake kwisidibanisi njengasesithombeni kwaye siyisuse ngononophelo ngaphandle kokwenza umgudu omkhulu. Njengoko ugxa wakho ecetyisiwe kuluvo, kufuneka nje utsale i-casing yeplastiki, hayi ucingo. Isidibanisi siphuma ngokucofa okuncinci.
Ewe, malunga nokudityaniswa okuchanekileyo kweengcingo, ndicinga ukuba akuyomfuneko ukubhala. Ukuba uye wenyuka ngaphakathi kwe-UPS, ngoko ngokucacileyo uyawazi umgaqo wonxibelelwano lweebhetri. Kwaye ngokuseleyo: isiqwenga sephepha okanye ipeni okanye i-smartphone enekhamera. Ekupheleni kwendibano, ukuba kunokwenzeka, silinganisa i-voltage kwindibano kunye nomhloli kwaye sithelekise kunye noko kufuneka kube, ngokusekelwe kwinani leebhetri.
"Ndenze yonke into njengoko kubhaliwe, kodwa akuzange kuncede."
Ewe, ngoku ubumnandi buqala. I-UPS, ngexesha lokusebenza kwayo, ngamaxesha (ngokuqhelekileyo kanye ngeentsuku ezi-7 okanye ezili-14, kuxhomekeke kwisethingi) yenza ukulinganisa okufutshane kwebhetri. Itshintshela kwimowudi yebhetri kwaye ilinganise amandla ombane ngoko nangoko nasemva kwexesha elifutshane. Isiphumo sale nto yinto ethile yokulungisa "ubomi bebhetri", engena kwirejista yayo. Njengoko ibhetri isifa ngokuthe ngcembe, imeko yale rejista iyancipha ngokuthe ngcembe. Ukusuka koku, i-UPS ibala ubomi bebhetri obushiyekileyo. Kwaye ke ngomzuzu omnye olungileyo, uqonda ukuba yonke into imbi, i-UPS ikhanyisa isalathisi esifuna ukuba ibhetri itshintshwe. Kodwa xa sithatha indawo, i-UPS ayazi ngayo! Ubume berejista "yobomi bebhetri" buhlala bufana. Kufuneka siyilungise.
Kukho iindlela ezimbini apha. Indlela yokuqala ilula kwaye iyakhawuleza - kufuneka ulungelelanise ngokupheleleyo i-UPS. Ukwenza oku, kufuneka ulayishe ngaphezu kwe-35% kwaye uqale ukulinganisa, umzekelo kwiprogram yePowerChute. Oku kusebenza malunga nesiqingatha sexesha. Kutheni kungasoloko kukho imfihlelo egutyungelwe bubumnyama. Ngoko ke, masithathe indlela ende kodwa ethembeke ngakumbi.
Siya kuyidinga: ikhompyutha ene-COM port, intambo yobunikazi (umzekelo 940-0024C), inkqubo ye-UpsDiag 2.0 (ukhuseleko lwe-UPS yakho, umlingane ucebisa ukuba kungcono ukusebenzisa i-apcfix kwimodi yamahhala. Ndiyakwazi Anditsho nantoni na malunga noku ngaphandle kokuba andikukhuthazi ukuba ucinezele kwi-UpsDiag enye into ngaphandle kokuhlela irejista 0, ngakumbi iqhosha lokulungisa impazamo yebhetri ezenzekelayo) kunye . Sinomdla kwixabiso lerejista 0. Itheyibhile ibonisa ixabiso leebhetri ezifanelekileyo, ezingqukuva kwi-vacuum. Naziphi na iibhetri zangempela ziya kunika ixabiso eliphantsi emva kokulinganisa, kodwa kungekhona kakhulu.
Umzekelo, ndiza kuthatha i-UPS SUA1500RMI2U yokwenyani. Ngexesha lokutshintshwa kwebhetri, i-UpsDiag ibonise ixabiso lerejista 0 - 42. Oko kukuthi, iibhetri zifile. Ixabiso lokulinganisa kwitheyibhile ngu-A1.
Siqala ukuhlela. Into yokuqala susa ikhadi lenethiwekhi kwi-UPS. Ukuba nekhadi lenethiwekhi akuyi kukunika ithuba lokuhlela irejista. Kutheni umbuzo kwiinjineli ze-APC. Ngethamsanqa, ungayikhupha ngelixa kushushu ngaphandle kokucima i-UPS.
Sidibanisa ikhebula, qalisa i-UpsDiag, uye kwithebhu ethi "Calibration" kwaye ujonge imeko yerejista 0. Yibhale phantsi kwiphepha lephepha, nqakraza kuyo - Guqula. Siyiphakamisa kwixabiso ukusuka kwitheyibhile yamaxabiso okulinganisa - A1. Ukuba i-UPS yakho ayikho etafileni, ngoko ke ngokomgaqo ungayiphakamisa kwi-FF. Akukho nto imbi enokuthi yenzeke kule nto, ngaphandle kwe-UPS ephazamisayo, eya kubonisa ukuba ilungele ukubamba umthwalo kude kube nokuza kwesibini.
Emva koko kufuneka silinde ibhetri ukuba ihlawule kwi-100%, layisha i-UPS ukuya kwi-35% okanye ngaphezulu kancinci kwaye uqale ukulinganisa. Ekupheleni kokulinganisa, siphinda sijonge ixabiso kwirejista ye-0 kwaye siyiqhathanise nento ebhaliweyo kwiphepha lephepha. Kwi-SUA1500RMI2U echazwe ngasentla kunye neebhetri ezintsha ze-HRL1234W, ixabiso libe yi-98, leyo, ngokomgaqo, ayikho kude kakhulu kwi-calibration A1.
Emva kwayo yonke into, sivumela ukuba sihlawule ukuya kwi-100% kwakhona, sikhuphe ikhebula le-COM, sivale ikhadi lenethiwekhi kwaye sinqwenelele i-UPS ubomi obude kunye nolonwabo kwinzuzo ye-server rack yethu.
Ngendlela, amakhadi womnatha afana ne-AP9619 kwimarike yesibini nayo yehla ngexabiso kumanqanaba amanyala. Kodwa indlela yokuzilungiselela (ukusetha kwakhona igama lokugqitha, ukuhlaziywa kwe-firmware, ukucwangciswa) sisihloko senqaku elahlukileyo.
