Unikezelo lwamandla olungaphazamisekiyo okanye i-UPS sisixhobo sombane esinokubonelela ngamandla angxamisekileyo ongezelelweyo kwimithwalo edityanisiweyo xa umbane oyintloko uphazamiseka.Inikwa amandla yibhetri yogcino de umbane ongundoqo ubuyiselwe.I-UPS ifakwe phakathi komthombo wamandla oqhelekileyo kunye nomthwalo, kwaye amandla anikezelweyo afikelela kumthwalo nge-UPS.Ngethuba lokuphuma kwamandla, i-UPS iya ngokuzenzekelayo kwaye ibone ngokukhawuleza ukulahlekelwa kwamandla okufakelwa kwamandla kunye nokutshintsha umbane wokuphuma kwibhetri.Olu hlobo lwebhetri logcino ludla ngokuyilwa ukunika amandla ixesha elifutshane de amandla abuyiselwe.
I-UPS idla ngokudityaniswa kumacandelo abalulekileyo angakwaziyo ukumelana nokucinywa kombane, njengedatha kunye nezixhobo zenethiwekhi.Zikwasetyenziselwa ukuqinisekisa ukuba umthwalo odibeneyo (nokuba ubalulekile okanye awukho) uyaqhubeka nokusebenza ngokufanelekileyo xa kwenzeka ukuhluleka kwamandla.Ezi zixhobo zinceda ukuthintela ixesha lokuphumla elibizayo, imijikelo enzima yokuqalisa kwakhona kunye nokulahleka kwedatha.
Nangona igama elithi UPS lamkelwa ngokubanzi libhekiselele kwinkqubo ye-UPS, i-UPS yinxalenye yenkqubo ye-UPS-nangona icandelo eliphambili.Inkqubo iyonke ibandakanya:
• Izixhobo zombane ezibona ukulahleka kombane kwaye zitshintshe imveliso esebenzayo ukutsalwa ebhetrini.
Okubonisiweyo apha kukudityaniswa kombane ongaphazamisekiyo okanye i-UPS enebhetri, i-electronics etshajayo, i-electronic control etshajayo, kunye neesokethi eziphumayo.
Inkqubo ye-UPS inikezelwa ngumenzi njengento yonke-kwinye (kunye ne-turn-key) icandelo;I-elektroniki ye-UPS kunye netshaja zihlanganiswe kwimveliso enye, kodwa ibhetri ithengiswa ngokwahlukileyo;kunye ne-UPS ezimeleyo ngokupheleleyo, ibhetri kunye neemveliso zetshaja yebhetri.Amacandelo adityaniswe ngokupheleleyo onke-kwinye axhaphake kakhulu kwiindawo ze-IT.Iinkqubo ze-UPS ezine-UPS kunye nee-elektroniki zetshaja ezingenazibhetri zezona zixhaphakileyo kwiindawo zemizi-mveliso ezifana nemigangatho yefektri.Uqwalaselo lwesithathu nolona lungaziwayo lusekwe kwi-UPS ebonelelweyo ngokwahlukeneyo, ibhetri, kunye netshaja yebhetri.
I-UPS ikwahlelwa ngokohlobo lomthombo wamandla (DC okanye AC) ezihambelana nawo.Zonke ii-AC UPSs zigcina imithwalo ye-AC… kwaye ngenxa yokuba ibhetri egciniweyo ngumthombo wamandla we-DC, olu hlobo lwe-UPS lunokwenza ugcino lwemithwalo ye-DC.Ngokwahlukileyo, i-DC UPS inokuxhasa kuphela i-DC-powered components.
Njengoko bekutshiwo ngaphambili, inkqubo ye-UPS ingasetyenziselwa ukongeza i-DC kunye ne-AC amandla amakhulu.Kubalulekile ukusebenzisa i-UPS echanekileyo yodidi lombane kwisicelo ngasinye.Ukuqhagamshela amandla e-AC kwi-DC UPS kuyawonakalisa amalungu… kwaye amandla e-DC awasebenzi kwi-AC UPS.Ukongezelela, inkqubo nganye ye-UPS inamandla alinganisiweyo kwi-watts-amandla aphezulu ukuba i-UPS inokubonelela.Ukuze unikeze ukukhuselwa okwaneleyo kwimithwalo edibeneyo, imfuno epheleleyo yamandla yazo zonke imithwalo edibeneyo akufanele idlule umthamo we-UPS.Ukulungelelanisa ubungakanani be-UPS ngokuchanekileyo, bala kwaye ushwankathele ireyithingi zamandla ngamnye kuwo onke amacandelo afuna amandla okugcina.Kucetyiswa ukuba injineli ichaze i-UPS emandla ayo alinganisiweyo angaphezulu kwama-20% ngaphezulu kwemfuneko yamandla ewonke.Eminye imiba yoyilo ibandakanya…
Sebenzisa ixesha: Inkqubo ye-UPS yenzelwe ukunika amandla ongezelelweyo kwaye ayinakusetyenziswa ixesha elide.Ukalo lwebhetri ye-UPS lukwiiyure ze-ampere (Ah), ichaza umthamo kunye nobude bebhetri… Umzekelo, ibhetri ye-20 Ah inokubonelela ngayo nayiphi na yangoku ukusuka kwi-1 A kwiiyure ezingama-20 ukuya kwi-20 A ngeyure enye.Ngalo lonke ixesha qwalasela ubude bexesha lebhetri xa ukhankanya inkqubo ye-UPS.
Abasebenzi bezolondolozo kufuneka baqonde ukuba umbane oyintloko kufuneka ubuyiselwe ngokukhawuleza, kwaye ibhetri ye-UPS ayikwazi ukukhutshwa ngokupheleleyo.Kungenjalo, ibhetri egciniweyo inokungqina ukuba ayonelanga… kwaye ushiye umthwalo obalulekileyo ngaphandle kwamandla konke konke.Ukunciphisa ixesha lokusetyenziswa kwebhetri egcinwayo kunokwandisa ubomi bebhetri.
Ukuhambelana: Ukusebenza kakuhle, unikezelo lwamandla, i-UPS, kunye nomthwalo odibeneyo kufuneka zonke zihambelane.Ukongeza, i-voltage kunye neereyithingi zangoku zazo zontathu kufuneka zihambelane.Le mfuno yokuhambelana nayo isebenza kuzo zonke iingcingo ezincedisayo kunye namacandelo aphakathi kwisistim (njengama-breaker circuit and fuses).Amacandelo angaphantsi (ingakumbi i-UPS yokulawula i-electronics kunye neetshaja) kwinkqubo ye-UPS eyenziwe ngumhlanganisi wenkqubo okanye i-OEM kufuneka nayo ihambelane.Khangela kwakhona ukuba iingcingo zalo naluphi na uyilo olunjalo lohlanganiso luchanekile...kuquka imidibaniso yetheminali kunye nokuthathela ingqalelo ipolarity.
Ngokuqinisekileyo, ukuhambelana kwamacandelo angaphantsi kwinkqubo ye-UPS edibeneyo iqinisekisiwe kuba oku kuvavanywa ngumthengisi ngexesha lokuvelisa kunye nokulawula umgangatho.
Indawo ekusetyenzwa kuyo: I-UPS inokufumaneka kwiindidi ezahlukeneyo zeendawo ezinomngeni kakhulu.Umenzi we-UPS uhlala echaza ubuninzi kunye nobuncinci bokushisa bokusebenza ekusebenzeni okuqhelekileyo kwenkqubo ye-UPS.Ukusetyenziswa ngaphandle kolu luhlu luchaziweyo kunokubangela iingxaki-kuquka ukusilela kwenkqubo kunye nomonakalo webhetri.Umenzi (enesatifikethi, imvume, kunye nokulinganisa) ukwachaza ukuba i-UPS inokumelana kwaye isebenze kwiindawo ezinobumanzi obahlukeneyo, uxinzelelo, ukuhamba komoya, ukuphakama, kunye namanqanaba amasuntswana.
