Ekuhlengeni okudityanisiwe ne-digital, Umkhiqizo Wamandla Ongavunyelwa (UPS) uyisikwe esenzelwa ukulahleka kwezethu, ukulwa kwezinhlobo, nokuthimekisa amandla. Ngenkathi kuzwa ukuthi kudingeka kube nezimiso zokusebenza, amandla, njll, kungenzeka ukuthi okunye kwezibonelo eziphambene nezinhlobo zokusebenza kungavunyelwa: umthamo wemigqa. Ukujwayele ukuthi le ncazelo yeyiphiyo yokuvikela ukuthi izinkundla zakho eziphambene zingavunyelwa.
Umthamo Wemigqa We-UPS Yiyiphi Na Noma Kungani Kudingeka?
Isikhathi sokushiphaya, okuvamile ukuthi kwi-milliseconds (ms) yilapho izikhathi ezinganeni efuneka u-UPS ukuthola ukuthi kukhona ukungcola okanye ukwehla kwezindleko eziphambene kuzindleko zase AC bese ukuqala ukusebenzisa ibetheni yayo. Kule ndawo encane okuthiwa yilapho u-UPS kufanele kuqinisekise okokuqala ukuthi ukungcola kwamandla akuyona into encane futhi engavunyelwa.
Ngakho ke yini eyona ngempela le ndawo encane? Ngoba ukungcola kwamandla kwi-milliseconds angamaqela kungaba nokuthi kuthiwe amandla kakhulu, kuthiwe, noma kuthiwe idatha, ukungcola kwamandla. Injongo ephambene yu-UPS ukuthi ikhankane amandla ngokwenkathi. Le ndawo ingaba yinto ephambene noma engaphambeni ngokwesibonelo esikhathini sokushiphaya. Ngaphansi kwezikhathi lokushiphaya, ngaphansi kwezikhathi efunekayo ukuthi kushiphwe, ngaphansi kwezikhathi ephambene nokwehluleka kumashini wakho.
Isikhathi Sokushiphaya Kuholela Kwamandla Amabi: Iziserver, Izinhlelo Zomedical, Fawuti
Ayikho ukuthi yonke into elekithoni yekhwankhwa ukuphazamiseka kwezimali ngokulinganisa. Ukuzithola kwayo kuyahlisa ngqo ukuzithola kwezithuba elincane.
I-IT & Network Infrastructure: I-server, izithuthi zokugcinwa, nezinhlelo zokuxhumana (izilayisi, iziswitchi) ziyakhathazeka kakhulu. Zingakwazi ukwenza ithuba lelayo noma ukuphazamisa ngokuphazamisa amandla kancane kakhulu ngama-1020 milliseconds. Lokhu kuyakhiwa ukuphazamisa kwe-server, ukuphazamiswa kwezidata, ukungena kwiziservice futhu ukugcinwa kwezinhlelo ngokuphazamisa ukuphela nokuthiwa kwizinto ngokugcwele.
Izinhlelo Zokugcinwa Kwemali & I-Laboratory: Izinhlelo zokubona (MRI), izinhlelo zokubonisa ngokudigitala nezinhlelo yokuvavanya ziyakhathazeka kakhulu futhu kakhulu kuzo zonke izindlela zokuvikela abantu. Yonke indlela yokuphazamisa amandla ingakwazi ukuthintana nezinyathelo ezijwayelekile, ukulahla uhlelo oluncane odinga ukucwaninga ngokucacile, noma ukuthiwa kuhlala kwezinyathelo eziningi zokulungisa kwakhona izinhlelo, ukuthwalwa kwezinyathelo ezithuthukisayo zokuvikela abantu.
Izinhlelo Zokulawulwa ePhedini: Izilawuli zemvelo, izinhlelo zokuzotheka kanye nezilawuli zokuthatha i-Programmable Logic (PLCs) use impahla ephindele impumelelo yokusebenza. Kungenzeka ukuthi kube nemva yemva embi engavimise ukulawula, kube ngemva yokulondoloza uhlelo lokwenza kanye nokuthumela kuqala ngendlela yokwenza, okuyindlela enkulu yokusebenza kanye nezimali.
Kulezi zinhlelo, isikhathi sokushiphiswa ngemizuzwana embi kungatholakali.
Ukuthani Ukukhetha i-UPS NgeSikhathi Sokushiphiswa Esifanele Kwezinyathelo Zakho
Umkhetho we-UPS enesikhathi sokushiphiswa esifanele siyindlela yokudala uhlelo oluhle lokuphepha impahla. Oku kuzodlala kakhulu kuzodlalwa ngokwechnoloji ngaphakathi kwe-UPS nje:
Ukuze wabelane nokuphepha kakhulu (Isikhathi sokushifayo 0ms): Lapho kubethwe izinhlelo eziphathelene nezinhlelo ezilandelayo, uneedinga ye-UPS enobuchwepheshe obabili. Lezi zinhlelo zishintsha ngokuvamile amandla we-AC kuya ku-DC (ukulayisha ibetheli) bese kuya ku-AC esihlukile (ukusela izinhlelo). Akukho shintsho noma ushintshana lapho kungena amandla ngoba ilayishwa iyasebenza ngokuvamile. Lokhu kabelana nezikhathi zokushintsha ezingama-milliseconds 0 futhu ukuphepha okuphezulu kakhulu kuleli ngqondo yonke.
Ukuphepha Ongqokwe (Ngokuvamile 2-10ms Isikhathi Sokushintsha): Kuzinhlelo ezingaphansi kwezimali eziphambene, njengokwehle elekitheni, izinkhomba zokusebenzela noma izinkhomba zokuthengisa, i-Line-interactive UPS ngokuvamile kungaba nokufanele. Lezi nhlelo zinezikhathi zokushintsha ezingaphezulu kunazo ezilandelayo ezingcono futhu nezokulungisa amandla (AVR) ukulungisa ukushontshelana okuncane ngaphandle kokuthi ibetheli isetshenziswa. Lezi nhlelo eziphambene ngokuvamile zingase kuthula izikhathi ezingaphezulu zokushintsha.
Xa uhlelo lwe-UPS, musa ukulahla ukubheka i-specification sheet yeqhuma letimelwe. Yabelana le nombolo ngokuvumelelwa kweqhuma. Uma kusebenza ngokusebenza kwe-infrastruktura ebalulekileyo, inqanaba le-double-conversion kufuneka libe yintanethi fano kufuneka libonise ukuthi ayikho itimela letimelwe.
Ekugcineni, isikhathi sokushiphaya akuyona kuphela indawo teknikhali- lokhu yilokho ekwenza uhlu phakathi kwe-UPS yakho enenxenye yebheti noma ube nezimali ezingalungiswa, amathile amathathu. Lapho uqinisekile ngemitheshwano yezithambo zakho bese ukhetha i-UPS enenkonzo ehambelana nezobuchwepheshe, imali yakho ingakunciphisa ubulungiswa ozidingayo.
