Amaziko edatha anamhlanje afuna ulawulo olucokisekileyo lwamandla. Kuyimfuneko ukujonga ngaxeshanye ubume bemithwalo nokulawula ukudityaniswa kwezixhobo. Oku kunokwenziwa ngokusebenzisa iikhabhinethi, iimodyuli okanye iiyunithi zokuhambisa amandla. Sithetha malunga naluphi uhlobo lwezixhobo zamandla ezifanelekileyo kwiimeko ezithile kwisithuba sethu usebenzisa imizekelo yezisombululo zeDelta.
Ukunika amandla iziko ledatha elikhula ngokukhawuleza lidla ngokuba ngumngeni. Izixhobo ezongezelelweyo kwii-racks, izixhobo eziya kwimodi yokulala, okanye, ngokuchaseneyo, ukunyuka komthwalo kukhokelela ekungalinganini kunikezelo lwamandla, ukwanda kwamandla asebenzayo kunye nokusebenza okuncinci kwenethiwekhi yombane. Iinkqubo zokuhambisa amandla zinceda ukuphepha ilahleko, ukuqinisekisa ukusebenza ngokufanelekileyo kwezixhobo kunye nokukhusela kwiingxaki ezinokwenzeka zokubonelela ngombane.
Xa uyila amanethiwekhi ombane, iingcali ze-IT zihlala zijongene nokhetho phakathi kweekhabhinethi, iimodyuli, kunye neeyunithi zokuhambisa amandla. Emva koko, ngokwenene, zonke iindidi ezintathu zezixhobo zixazulula iingxaki ezifanayo, kodwa kumanqanaba ahlukeneyo kunye neeseti ezahlukeneyo zokukhetha.
Ikhabhinethi yokuhambisa amandla
Ikhabhinethi yokusabalalisa amandla, okanye iPDC (ikhabhinethi yokusabalalisa amandla), sisixhobo sokulawula amandla aphezulu. Ikhabhinethi ikuvumela ukuba ulungelelanise ukunikezelwa kwamandla kwi-racks ezininzi kwiziko ledatha, kunye nokusetyenziswa kweekhabhinethi ezininzi ngexesha elinye kwenza kube lula ukulawula ukusebenza kwamaziko amakhulu edatha. Ngokomzekelo, izisombululo ezifanayo zisetyenziswa ngabaqhubi beeselula - ukubonelela umbane kwiziko ledatha elinama-racks angama-5000, ngaphezu kwe-50 iikhabhinethi zokuhambisa amandla zazifuneka, e Shanghai.
Ikhabhinethi ye-Delta InfraSuite yePDC, enobukhulu obufanayo nekhabhinethi eqhelekileyo ye-intshi ye-19, iquka iibhanki ezimbini ze-single-pole breakers circuit breakers ezikhuselwe ngamaqhekeza awongezelelweyo. Ikhabhinethi inokulawula iiparitha zangoku zesekethe nganye kunye nokutshintsha okuhlukileyo. Ikhabhinethi yokusabalalisa amandla ine-alarm eyakhelwe-ngaphakathi yokwabelana ngomthwalo ongalinganiyo. Njengokhetho, iikhabhinethi zeDelta zixhotyiswe ngeenguqu ezongezelelweyo zokuvelisa amandla ombane ahlukeneyo, kunye neemodyuli zokukhusela kwingxolo ye-impulse, ezifana nezo zidalwe ngokukhutshwa kombane.
Ukulawula, ungasebenzisa umboniso we-LCD owakhelwe ngaphakathi, kunye neenkqubo zolawulo lwamandla zangaphandle eziqhagamshelwe nge-RS232 ye-serial interface okanye nge-SNMP. Isixhobo sixhunyiwe kwinethiwekhi yangaphandle ngemodyuli ekhethekileyo ye-InsightPower. Ikuvumela ukuba uthumele izilumkiso, idatha yephaneli yolawulo kunye neeparamitha zobume bosasazo lwenethiwekhi kumncedisi ophakathi. Eli licandelo eliphambili elenza ulawulo olukude kunye nokubeka iliso, kwaye yazisa iinjineli zenkqubo yeziganeko ezibalulekileyo nge-SNMP imigibe kunye ne-imeyile.
Iingcali ezisebenza kwiziko ledatha zinokufumanisa ukuba yeyiphi isigaba esilayishwe ngaphezulu kunabanye kwaye sitshintshele abanye abathengi kwindawo encinci okanye ukucwangcisa ukufakwa kwezixhobo ezongezelelweyo ngexesha elifanelekileyo. Isikrini sinokubeka iliso kwiiparamitha ezifana nobushushu, ukuvuza komhlaba ngoku, kunye nobukho okanye ukungabikho komlinganiselo wombane. Inkqubo ine-log eyakhelwe-ngaphakathi egcina iirekhodi ze-500 zeziganeko zekhabhinethi, ezikuvumela ukuba ubuyisele ulungelelwaniso olufunwayo okanye uhlalutye iimpazamo ezandulela ukuvala ngokukhawuleza.
Ukuba sithetha ngoluhlu lwemodeli ye-Delta, i-PDC ixhunyiwe kwinethiwekhi yesigaba sesithathu kwaye inokusebenza nge-voltage ye-220 V kunye nokuphambuka okungaphezu kwe-15%. Umgca uquka iimodeli ezinamandla angama-80 kVA kunye ne-125 kVA.
Iimodyuli zokuhambisa amandla
Ukuba ikhabhinethi yokusabalalisa amandla yikhabhinethi eyahlukileyo enokuthi ihanjiswe ngeenxa zonke kwiziko ledatha kwimeko yokuphuhliswa kwakhona okanye utshintsho kwindawo yomthwalo, ngoko ke iinkqubo zemodyuli zikuvumela ukuba ubeke izixhobo ezifanayo ngokuthe ngqo kwii-racks. Zibizwa ngokuba yi-RPDC (iKhabhinethi yoSasazo lwaMandla eRack) kwaye ziikhabhathi ezincinci zokuhambisa ezithatha i-4U kwirack eqhelekileyo. Izisombululo ezinjalo zisetyenziswa ziinkampani ze-Intanethi ezifuna ukusebenza okuqinisekisiweyo kweqela elincinci lezixhobo. Ngokomzekelo, iimodyuli zokusabalalisa zifakwe njengenxalenye yesisombululo esibanzi sokukhusela iziko ledatha Jemani.
Xa kuziwa kwizixhobo ze-Delta, iyunithi enye ye-RPDC inokulinganiswa kwi-30, i-50 okanye i-80 kVA. Iimodyuli ezininzi zinokufakwa kwi-rack eyodwa ukunika amandla yonke imithwalo kwiziko ledatha encinci, okanye i-RPDC enye inokufakwa kwii-racks ezahlukeneyo. Olu khetho lokugqibela lufanelekile ukunika amandla iiseva ezinamandla ezifuna ulawulo lonikezelo lwamandla kunye nolwabiwo lwamandla kwakhona ngokuxhomekeke kubumbeko kunye nomthwalo.
Inzuzo yenkqubo yemodyuli kukukwazi ukwandisa amandla njengoko isikhungo sedatha sikhula kunye nezikali. Abasebenzisi bahlala bekhetha i-RPDC xa ikhabhinethi epheleleyo idala i-headroom eninzi kakhulu kwi-configuration yangoku ye-2-3 i-racks yezixhobo.
Imodyuli nganye ixhotyiswe ngesikrini esichukumisayo esiphantse sibe namandla afanayo okulawula njengePDC eyahlukileyo, kwaye ixhasa ujongano lwe-RS-232 kunye namakhadi ahlakaniphile okulawula kude. Iimodyuli zokusabalalisa zibeke iliso okwangoku kwiisekethe ezidibeneyo, zazise ngokuzenzekelayo malunga neemeko ezingxamisekileyo kunye nokuxhasa ukutshintshwa okutshisayo kwezixhobo zokutshintsha. Idatha yesimo senkqubo irekhodwa kwilog yesiganeko, enokugcina ukuya kuma-2 amangeno.
Iiyunithi zokuhambisa amandla
Iiyunithi zokuhambisa amandla zezona nkqubo zidibeneyo kunye neendleko ezisebenzayo kolu didi. Bakuvumela ukuba ulawule ukusebenza kwezixhobo ngaphakathi kwi-rack enye, ukubonelela ngolwazi malunga nomgangatho wemigca kunye nomthwalo. Ngokomzekelo, iibhloko ezinjalo zazisetyenziselwa ukuxhobisa Β» eSt. Petersburg kunye Consortium "Digital Enterprise" e Chelyabinsk.
Iiyunithi ziza kwiifomathi ezahlukeneyo, kodwa iimodeli ezenziwe kusetyenziswa itekhnoloji ye-Zero-U zibekwe kwi-rack efanayo nesixhobo esiphambili, kodwa azihlali "iiyunithi" ezahlukileyo - zixhonywe ngokuthe nkqo okanye ngokuthe tye kwizinto zesakhiwo zisebenzisa izibiyeli ezikhethekileyo. Oko kukuthi, ukuba usebenzisa i-rack ye-42U, emva kokufaka iyunithi, yile nto kanye ukuba zingaphi iiyunithi oya kuba nazo. Ibhloko nganye yokusabalalisa inenkqubo yayo ye-alamu: ubukho bomthwalo okanye imeko engxamisekileyo kwimigca nganye ephumayo ichazwa zizibonakaliso ze-LED. Iiyunithi zeDelta zine-interface ye-RS232 kwaye zidibanisa kwiinkqubo zokubeka iliso nge-SNMP, njengeekhabhinethi kunye neemodyuli zokuhambisa amandla.
Ukulinganisa kunye neeyunithi ezisisiseko zokusabalalisa zingafakwa ngokuthe ngqo kwi-rack, zombini kwi-dealta yoyilo oluqhelekileyo kunye nakwii-racks ezivela kwabanye abavelisi. Oku kunokwenzeka ngenxa yeseti yendalo yonke yezibiyeli. Iiyunithi zokuhambisa amandla zinokufakelwa ngokuthe nkqo nangokuthe tyaba, kwaye zingasetyenziselwa ukubonelela ngombane kwisigaba esinye kunye nesigaba sesithathu sothungelwano. Ubuninzi bangoku kwiiyunithi zokusabalalisa i-Delta yi-32 A, ukuphambuka kwe-voltage yegalelo ukuya kwi-10%. Kunokubakho i-6 okanye i-12 izixhumanisi zokudibanisa umthwalo.
Into ephambili kukudala inkqubo yolawulo olubanzi
Ukhetho phakathi kwekhabhinethi, ibhloko okanye imodyuli ixhomekeke kuwuphi umthwalo omele uxhunywe. Amaziko amakhulu edatha afuna iikhabhinethi zokusabalalisa, nangona kunjalo, azibandakanyi ukufakwa kweemodyuli ezongezelelweyo okanye iiyunithi zamandla e-branching kwimithwalo yomntu.
Kumagumbi omncedisi ophakathi, imodyuli enye okanye ezimbini zokuhambisa zihlala zanele. Inzuzo yesi sisombululo kukuba inani leemodyuli linokunyuswa, ukukala inkqubo yokunikezelwa kwamandla kunye nophuhliso lweziko ledatha.
Iiyunithi zokusabalalisa zivame ukufakwa kwii-racks ezihlukeneyo, eziya kukwanela ukuxhobisa igumbi elincinci leseva. Ngenkqubo yolawulo edibeneyo, banikezela ngokukwazi ukubeka iliso kunye nokulawula ukusetyenziswa kwamandla, kodwa ungavumeli ukuhanjiswa okuguquguqukayo kwemigca kunye nokutshintshwa okutshisayo kwezinto zoqhagamshelwano kunye nokuhanjiswa.
Kumaziko edatha yanamhlanje unokufumana ngaxeshanye iikhabhinethi, iimodyuli, kunye neeyunithi zokuhambisa amandla ezifakwe ngamaxesha ahlukeneyo kunye neenjongo ezahlukeneyo. Into ephambili kukudibanisa zonke izixhobo zokulawula amandla zibe yinkqubo enye yokubeka iliso. Kuya kukuvumela ukuba ubeke iliso nakuphi na ukuphambuka kwiiparitha zonikezelo lwamandla kwaye ngokukhawuleza uthathe inyathelo: tshintsha izixhobo, ukwandisa amandla okanye ukuhambisa umthwalo kwezinye imigca / izigaba. Oku kunokwenziwa ngesoftware efana neDelta InfraSuite okanye imveliso efanayo.
