Ukukhetha indawo yokulayisha yamanzi (UPS) enokubaluleka kakhulu ukulondoloza iindleke zakho. Enye yeendawo ebalulekileyo zokucaciswa ngu- power ratings kunye ne-load capacity. Ukwenza impazamo kuya kubangela ukungabi nangeli kweenkqubo, ukugcina amagadgets, okanye izindleko ezingavumelekanga. Oku kuya kunceda wokulayisha le ziganeko ezibalulekileyo.
Ukuchaza i-kVA, i-kW, kunye ne-Power Factor kwi-UPS Systems
Ukukhetha i-UPS ecacileyo, kufuneka uqiniseke ukuba uyazi kumbi iindlela zokubala. Ezibini eziphambeneyo ngu-kVA kunye ne-kW.
Inkcazo ye apparent power ngu kVA (kilovolt-ampere). Iyinto enkathali yalo wonke amaphrojekthi amathile aza kuthunyelwa na le UPS. kW (kilowatt) isetshenziswa ukuncipha kwe real power. Lokhu ngu amandla aphumelelayo okwenza umsebenzi wakho ukuqasha izivivinye kanye nezinhlelo zokuphrinta.
Ukuxhuma phakathi kwezinye zombili izinhlobo le kaphakathi ngu power factor (PF) engubani kusukela ku 0 kuya ku 1. kW = kVA x Power Factor ngubani obulali. Izinhlelo zamanje ezisemqamaweni jikelela izinhlelo zokusebenza (0.9 noma ngaphezulu). Lokhu kusho ukuthi into engenayo amandla aphumelelayo amaningi ayithola amandla aphumelelayo (kW) edlule kakhulu kuye kwe apparent power (kVA) yakhe.
Kuqala kusukela, ukuhluka phakathi kwe kVA kanye nezinhlobo zokuthunyelwa kwe kW kuthiwile ukuphikisaniswa. Isifundo esikhulu manje ngu ukuthi kufanele uthenge i-UPS ngokulingana nezimali (kW) eziphilayo kanye nezimali zakho, kungenkonzeki kuphela ngokulingana ne kVA.
Kungani Kudinga Okanye Ukuncipha Okuningi I-UPS Yakho Kungadinga
Kunemaphayela okukhulu ukudla kuphumelela kwe-UPS engiyona enkulu noma encane futhi ayilandelani nge-load yakho.
Ukuncane kwe-UPS yakho kuyi-riski enkulu. Uma imicemu engxunywe nezimala eziphakeme kunezoqu kuyona ku-UPS iyodla. Lokhu kungenzeka ukuba ku-UPS kube khona ukuguqula kuma-bypass noma kube yini, kubonisa imicemu yakho ebaluleke kuma-anomalies wokusebenza kanye nezindlala zokusebenza. Khona futhi ukwenza ngaphezulu kungase kuthiwe ukuphoyiswa okungavunyelwa kwe-UPS naye.
Ukuthanda ukukhuluza kakhulu i-UPS yakho kungaba yimali, kodwa kuzosungula ukungahlanjiswa. I-UPS systems inezimandla efanayo zokulayisha okungcono xa sebenzisa ngaphakathi kwezinkinga efanayo ezingu-50-80 phesenti ye-engile. I-UPS enkulu kakhulu ingaba yindlethekile, ngoko uyathula imali, uyakhula izindleko zemali futhi ingaba yasalela ukuphila kwamapili ngokuhlanganisa ukulayishwa okuncane. Kufanayo kubaluleka ukuthatha isicelo esikhulu esingcono sokuthola i-inthanethi.
Ukuvikela Imali Yakho Ngokwesibonelo Sokulayisha
Izidingo zakho zemali azoyibi. Inqubomgomo yemali yokuvikela kudinga ukuplanisa ukuthuthukiswa kwamandla.
Kunokuthiwa kusukela kwi-UPS system, bona ukuba kungenhla. I-UPS evela ngamanye amakhiwane kuyakuvumela ukuthi uqale nge-loko onayo okwenzelwa ngumuntu oka-baseline othola lelo kungenhla okwenzelwa manje. Iindlela zokusebenza ngale ndlela kwekhiwane ngokwengeziwe kwi-infrastructure yakho ye-IT ukuthola i-KW kunye ne-KVA ye-system yakho, ngokudinga ukuthi wakhi ngokupheleleyo i-system entsha. Le yindlela enesandla yokupheya indawo yakho yokuqala kunye nokunika inketho yokusebenzisa nezidingo eziphutha ngokulandela.
I-nyathelo lokuqala ngaphambi kokukhetha i-UPS kufuneka uyavumele ukuba ngubani i-KW yakho yokuqala, emva koko iprojekthi iyakuba ngokwazo ukuthi unyuka kanjani kwiiminyaka elilandelayo 3-5. Loku kuyakunceda ukukhetha isisombululo esifakelwa kuzo zonke iinkxalothando zakho zokuqala kunye nokunika indlela ehle neyodwa yokunceda-ukupheya iindlela zakho zokusebenza kunye nokuthi kuyafumana okuningi njengoko ukuphutha kwesikole yakho.
