Izikhungo zedatha zanamuhla zidinga ukuphathwa ngokucophelela kwamandla. Kuyadingeka ukuqapha ngesikhathi esisodwa isimo semithwalo futhi uphathe ukuxhumeka kwemishini. Lokhu kungenziwa ngokusebenzisa amakhabethe, amamojula noma amayunithi okusabalalisa amandla. Sikhuluma ngokuthi yiluphi uhlobo lwemishini yamandla olufaneleka kangcono izimo ezithile kokuthunyelwe kwethu sisebenzisa izibonelo zezixazululo zeDelta.
Ukunika amandla isikhungo sedatha esikhula ngokushesha ngokuvamile kuwumsebenzi oyinselele. Imishini eyengeziwe kuma-racks, okokusebenza okuya kumodi yokulala, noma, ngokuphambene, ukwanda komthwalo kuholela ekungalinganini kokunikezwa kwamandla, ukwanda kwamandla asebenzayo kanye nokusebenza okuncane kwenethiwekhi kagesi. Izinhlelo zokusabalalisa amandla zisiza ukugwema ukulahlekelwa, ziqinisekise ukusebenza kahle kwemishini futhi zivikeleke ezinkingeni zokuphakelwa kwamandla okungenzeka.
Lapho beklama amanethiwekhi wamandla, ochwepheshe be-IT bavame ukubhekana nokukhetha phakathi kwamakhabethe, amamojula, namayunithi okusabalalisa amandla. Phela, empeleni, zonke izigaba ezintathu zamadivayisi zixazulula izinkinga ezifanayo, kodwa emazingeni ahlukene kanye nesethi ehlukile yezinketho.
Ikhabhinethi yokusabalalisa amandla
Ikhabhinethi yokusabalalisa amandla, noma i-PDC (ikhabethe lokusabalalisa amandla), iyidivayisi yokulawula amandla esezingeni eliphezulu. Ikhabhinethi ikuvumela ukuthi ulinganise ukunikezwa kwamandla kwenqwaba yama-racks esikhungweni sedatha, futhi ukusetshenziswa kwamakhabhinethi amaningana ngesikhathi esisodwa kwenza kube nokwenzeka ukulawula ukusebenza kwezikhungo ezinkulu zedatha. Isibonelo, izixazululo ezifanayo zisetshenziswa opharetha bamaselula - ukunikeza amandla esikhungweni sedatha esinama-racks angu-5000, amakhabethe okusabalalisa amandla angaphezu kuka-50 ayedingeka, e-Shanghai.
Ikhabhinethi ye-Delta InfraSuite PDC, engusayizi ofanayo nekhabethe elijwayelekile lama-intshi angu-19, ihlanganisa amabhange amabili ama-circuit breaker anesigxobo esisodwa avikelwe ama-breaker engeziwe. Ikhabhinethi ingakwazi ukulawula imingcele yamanje yesifunda ngasinye ngokushintsha okuhlukile. Ikhabhinethi yokusabalalisa amandla inesistimu ye-alamu eyakhelwe ngaphakathi yokwabelana ngomthwalo ongalingani. Njengenketho, amakhabethe e-Delta afakwe ama-transformer engeziwe ukuze akhiqize ama-voltage ahlukene okukhiphayo, kanye namamojula okuvikela emsindweni oshukumisayo, njengalawo adalwe ukukhishwa kombani.
Ukuze ulawule, ungasebenzisa isibonisi se-LCD esakhelwe ngaphakathi, kanye namasistimu okuphatha amandla angaphandle axhunywe nge-serial interface ye-RS232 noma nge-SNMP. Idivayisi ixhunywe kunethiwekhi yangaphandle ngemojula ekhethekile ye-InsightPower. Ikuvumela ukuthi udlulise izexwayiso, idatha yephaneli yokulawula kanye nemingcele yesimo senethiwekhi yokusabalalisa kuseva emaphakathi. Lena ingxenye eyinhloko enika amandla ukuphathwa nokuqapha okukude, futhi yazisa onjiniyela besistimu ngezehlakalo ezibucayi ngezicupho ze-SNMP ne-imeyili.
Ochwepheshe abasebenza isikhungo sedatha bangathola ukuthi yisiphi isigaba esilayishwe kakhulu kunezinye futhi bashintshe abanye abathengi baye kwesilayishwe kancane noma bahlele ukufakwa kwezisetshenziswa ezengeziwe ngesikhathi. Isikrini singakwazi ukuqapha amapharamitha afana nezinga lokushisa, amandla okuvuza komhlabathi, kanye nokuba khona noma ukungabikho kwebhalansi kagesi. Uhlelo lunologi olwakhelwe ngaphakathi olugcina amarekhodi angama-500 emicimbi yekhabhinethi, okuvumela ukuthi ubuyisele ukucushwa okufunayo noma uhlaziye amaphutha angaphambi kokuvalwa kwezimo eziphuthumayo.
Uma sikhuluma ngebanga lemodeli ye-Delta, i-PDC ixhunywe kunethiwekhi yezigaba ezintathu futhi ingasebenza nge-voltage engu-220 V ngokuphambuka okungaphezu kuka-15%. Ulayini uhlanganisa amamodeli anamandla angu-80 kVA kanye no-125 kVA.
Amamojula okusabalalisa amandla
Uma ikhabethe lokusabalalisa amandla liyikhabhinethi ehlukile enganyakaziswa eduze kwesikhungo sedatha uma kwenzeka ithuthukiswa kabusha noma izinguquko endaweni yomthwalo, khona-ke amasistimu we-modular akuvumela ukuthi ubeke okokusebenza okufanayo ngqo kuma-rack. Abizwa nge-RPDC (Ikhabhinethi Yokusabalalisa Amandla E-Rack) futhi angamakhabethe amancane okusabalalisa athatha i-4U endaweni yokubeka ejwayelekile. Izixazululo ezinjalo zisetshenziswa izinkampani ze-inthanethi ezidinga ukusebenza okuqinisekisiwe kwemikhumbi emincane yemishini. Isibonelo, amamojula okusabalalisa afakwe njengengxenye yesixazululo esibanzi sokuvikela isikhungo sedatha EJalimane.
Uma kukhulunywa ngemishini ye-Delta, iyunithi eyodwa ye-RPDC ingakalwa ku-30, 50 noma 80 kVA. Amamojula amaningi angafakwa ku-rack eyodwa ukuze anike amandla yonke imithwalo esikhungweni sedatha encane, noma i-RPDC eyodwa ingafakwa kuma-rack ahlukene. Inketho yokugcina ifanele ukunika amandla amaseva anamandla adinga ukulawulwa kokunikezwa kwamandla nokusabalalisa kabusha kwamandla kuye ngokucushwa nokulayisha.
Inzuzo yesistimu ye-modular yikhono lokukhulisa amandla njengoba isikhungo sedatha sikhula futhi sikala. Abasebenzisi bavame ukukhetha i-RPDC lapho ikhabhinethi egcwele ngokugcwele idala i-headroom eningi kakhulu ekucushweni kwamanje kwama-rack angu-2-3 wezinto zokusebenza.
Imojula ngayinye ifakwe isikrini sokuthinta esinamandla afanayo okulawula njenge-PDC ehlukile, futhi futhi isekela ukuxhumana kwe-RS-232 namakhadi ahlakaniphile okulawula kude. Amamojula okusabalalisa aqapha okwamanje kumjikelezo ngamunye axhunyiwe, azisa ngokuzenzakalelayo ngezimo eziphuthumayo futhi asekele ukushintshwa okushisayo kwamadivaysi okushintsha. Idatha yesimo sesistimu irekhodwa kulogi yomcimbi, engagcina kufikela kokufakiwe okungu-2.
Amayunithi wokusabalalisa amandla
Amayunithi okusabalalisa amandla yizinhlelo ezihlangene kakhulu futhi ezingabizi kakhulu kulesi sigaba. Bakuvumela ukuthi ulawule ukusebenza kwemishini ngaphakathi kwe-rack eyodwa, ukunikeza ulwazi mayelana nesimo semigqa nomthwalo. Isibonelo, amabhlogo anjalo asetshenziselwa ukuhlomisa Β» eSt. Petersburg kanye Consortium "Digital Enterprise" e Chelyabinsk.
Amayunithi eza ngamafomethi ahlukene, kodwa amamodeli enziwe kusetshenziswa ubuchwepheshe be-Zero-U abekwe endaweni yokubeka efanayo nemishini eyinhloko, kodwa awathathi βamayunithiβ ahlukene - agibelekwa aqondile noma avundlile ezintweni zesakhiwo kusetshenziswa abakaki abakhethekile. Okusho ukuthi, uma usebenzisa i-rack ye-42U, ngemuva kokufaka iyunithi, yilokhu mangaki amayunithi ozosala nawo. Ibhulokhi ngayinye yokusabalalisa inesistimu yayo ye-alamu: ukuba khona komthwalo noma isimo esiphuthumayo emigqeni ngayinye ephumayo kubikwa izinkomba ze-LED. Amayunithi e-Delta anokuxhumana kwe-RS232 futhi axhumeka ezinhlelweni zokuqapha nge-SNMP, njengamakhabhinethi namamojula okusabalalisa amandla.
Amayunithi amamitha kanye nokusabalalisa ayisisekelo angafakwa ngqo endaweni yokubeka, kokubili kumadizayini ajwayelekile we-Delta kanye nama-rack avela kwabanye abakhiqizi. Lokhu kungenzeka ngenxa yeqoqo lomhlaba wonke labakaki. Amayunithi okusabalalisa amandla angafakwa aqonde phezulu futhi avundlile, futhi angasetshenziswa ukuhlinzeka ugesi ovela kunethiwekhi yesigaba esisodwa kanye nezigaba ezintathu. Umkhawulo wamanje wamayunithi wokusabalalisa we-Delta ngu-32 A, ukuchezuka kwamandla kagesi okufakwayo kufike ku-10%. Kungaba nezixhumi eziyi-6 noma eziyi-12 zokuxhuma umthwalo.
Into esemqoka ukudala uhlelo oluphelele lokuphatha
Ukukhetha phakathi kwekhabhinethi, ibhulokhi noma imodyuli kuncike ekutheni imuphi umthwalo odinga ukuxhunywa. Izikhungo ezinkulu zedatha zidinga amakhabhinethi okusabalalisa, okuyinto, noma kunjalo, ingabandakanyi ukufakwa kwamamojula engeziwe noma amayunithi wamandla we-branching emithwalweni ngayinye.
Emakamelweni eseva anosayizi ophakathi, imojula eyodwa noma amabili okusabalalisa ngokuvamile anele. Inzuzo yalesi sixazululo ukuthi inani lamamojula linganyuswa, ukukala uhlelo lokuhlinzeka ngamandla kanye nokuthuthukiswa kwesikhungo sedatha.
Amayunithi okusabalalisa ngokuvamile afakwa kuma-racks ahlukene, azokwanela ukuhlomisa igumbi elincane leseva. Ngesistimu yokulawula ehlanganisiwe, baphinde banikeze amandla okuqapha nokulawula ukusetshenziswa kwamandla, kodwa akuvumeli ukusabalalisa kabusha okunamandla kwemigqa nokushintshwa okushisayo kwezinto zokuxhumana kanye nokudluliswa kwemali.
Ezikhungweni zedatha zesimanje ungathola ngesikhathi esisodwa amakhabethe, amamojula, namayunithi okusabalalisa amandla afakwe ngezikhathi ezihlukene nangezinhloso ezahlukene. Into eyinhloko ukuhlanganisa yonke imishini yokuphatha amandla ohlelweni olulodwa lokuqapha. Izokuvumela ukuthi uqaphe noma yikuphi ukuphambuka kumapharamitha wokuphakela amandla futhi uthathe isinyathelo ngokushesha: shintsha izisetshenziswa, wandise amandla noma uhambise umthwalo kwezinye imigqa/izigaba. Lokhu kungenziwa ngesofthiwe efana ne-Delta InfraSuite noma umkhiqizo ofanayo.
