Zeziphi iintlobo zombane we-UPS ezihlulwe ngokwemigaqo yokusebenza? Umbane we-UPS ongaphazanyiswayo wahlulwe ngokwamaqela amathathu: i-backup, i-intanethi kunye ne-intanethi ye-interactive UPS. Ukusebenza kombane we-UPS ukusuka phezulu ukuya ezantsi kungoku: utshintsho oluphindwe kabini kwi-intanethi, i-intanethi ye-interactive, uhlobo lwe-backup. Ixabiso ngokubanzi lihambelana nokusebenza. Ukuqonda indlela yokusebenza yombane we-UPS kunokunceda ukukhusela ngcono umbane we-UPS kulondolozo lwemihla ngemihla.
Zeziphi iintlobo zombane ze-UPS ezihlulwe ngokwemigaqo yokusebenza?
Umbane we-UPS yinto esihlala siyibiza ngokuba yi-UPS uninterruptible power supply. Umbane we-UPS usebenza ngeendlela ezintathu ezilandelayo:
1. Umbane we-backup UPS unikezelwa ngqo ukusuka kwi-mains ukuya kumthwalo xa i-mains iqhelekile. Xa i-mains idlula umda wayo wokusebenza okanye umbane uphela, umbane uguqulwa ube yi-inverter yebhetri ngeswitshi yokuguqula. Ibonakaliswa yisakhiwo esilula, umthamo omncinci kunye neendleko eziphantsi, kodwa uluhlu lwe-input voltage luncinci, i-output voltage izinzile kwaye ukuchaneka kwayo akukuhle, kukho ixesha lokutshintsha, kwaye i-output waveform ngokubanzi yi-square wave.
Isiphumo se-backup sine wave supply UPS power: isiphumo seyunithi singaba yi-0.25KW~2KW. Xa i-mains itshintsha phakathi kwe-170V~264V, i-UPS idlula i-170V~264V.
2. Umbane we-UPS osebenzisanayo kwi-intanethi unikezelwa ngokuthe ngqo ukusuka kwii-mains ukuya kumthwalo xa ii-mains ziqhelekile. Xa ii-mains ziphantsi okanye ziphezulu, umgca wolawulo lwangaphakathi lwe-UPS uyaphuma. Xa umbane we-UPS ungaqhelekanga okanye ucinyiwe, umbane uguqulwa ube yi-inverter yebhetri ngeswitshi yokuguqula. Ubonakaliswa luluhlu olubanzi lwe-input voltage, ingxolo ephantsi, ivolumu encinci kunye nezinye iimpawu, kodwa kukwakho nexesha lokutshintsha.
Umbane we-UPS osebenzisanayo kwi-intanethi unomsebenzi wokucoca, amandla okuphazamisana nesixeko aqinileyo, ixesha lokuguqula lingaphantsi kwe-4ms, kwaye i-inverter output yi-analog sine wave, ngoko ke inokuxhotyiswa ngee-server, ii-routers kunye nezinye izixhobo zenethiwekhi, okanye isetyenziswe kwiindawo ezinendawo enamandla ombane.
3. Umbane we-UPS okwi-intanethi, xa ii-mains ziqhelekile, ii-mains zibonelela nge-DC voltage kwi-inverter ukuya kumthwalo; xa ii-mains zingaqhelekanga, i-inverter inikwa amandla yibhetri, kwaye i-inverter isoloko ikwimeko yokusebenza ukuqinisekisa ukuphuma okungaphazamisekiyo. Ibonakaliswa luluhlu olubanzi kakhulu lwe-input voltage, ngokusisiseko akukho xesha lokutshintsha kunye nozinzo lwe-output voltage kunye nokuchaneka okuphezulu, ngakumbi ezifanelekileyo kwiimfuno zombane eziphezulu, kodwa iindleko ziphezulu. Okwangoku, umbane we-UPS onamandla angaphezu kwe-3 KVA phantse wonke umbane we-UPS okwi-intanethi.
Ulwakhiwo lwamandla e-UPS olukwi-intanethi luyinkimbinkimbi, kodwa lusebenza ngokugqibeleleyo kwaye lunokusombulula zonke iingxaki zobonelelo lwamandla, njengothotho lwe-PS oluneendlela ezine, olukwaziyo ukukhupha i-AC ye-sine wave ecocekileyo rhoqo ngaphandle kokuphazamiseka, kwaye lunokusombulula zonke iingxaki zamandla ezifana nokujika, ukunyuka, ukushukuma kwamaza; lufuna utyalo-mali olukhulu, ludla ngokusetyenziswa kwindawo yamandla anzima kwizixhobo ezibalulekileyo nakwiziko lenethiwekhi.
Iindlela ezine zokusebenza kwe-UPS UPS
Ngokuxhomekeke kwimeko yokusetyenziswa, umbane we-UPS ongaphazanyiswayo unokuguqulelwa kwiindlela ezine zokusebenza ezahlukeneyo: imo yokusebenza eqhelekileyo, imo yokusebenza yebhetri, imo yokusebenza ye-bypass kunye nemo yokulungisa i-bypass.
1. ukusebenza okuqhelekileyo
Kwiimeko eziqhelekileyo, umgaqo wobonelelo lwamandla wenkqubo yobonelelo lwamandla olungenakuphazamiseka lwe-UPS kukuguqula amandla okufaka i-AC abe ngumbane olawulayo xa isixeko siqhelekile, uze utshaje ibhetri ukuze kusetyenziswe ukuphazamiseka kwamandla; kufuneka kugxininiswe ukuba inkqubo yobonelelo lwamandla ye-UPS ayisebenzi xa umbane ungasebenzi, ukuba i-voltage iphantsi kakhulu okanye iphezulu kakhulu, ukuqhuma kwangoko okuchaphazela umgangatho wamandla okusebenza kwesixhobo, inkqubo ye-UPS ikwimeko yokusebenza ukubonelela ngobonelelo lwamandla oluzinzileyo nolucocekileyo kwizixhobo zomthwalo.
2. Ukusebenza ngokudlula
Xa ii-mains ziqhelekile, xa amandla e-UPS ebonakala egqithisile, umyalelo we-bypass (ngesandla okanye ngokuzenzekelayo), i-inverter igqithisa kakhulu okanye ukungasebenzi komatshini, amandla e-UPS ajika i-inverter output iye kwi-bypass output, oko kukuthi, inikezelwa ngokuthe ngqo zii-mains. Ekubeni isigaba se-UPS frequency output kufuneka sifane ne-mains frequency ngexesha le-bypass, itekhnoloji yokuvumelanisa i-phase lock iyasetyenziswa ukuqinisekisa ukuba i-UPS power output ihambelana ne-mains frequency.
3. Ukugcinwa kwe-bypass
Xa umbane ongxamisekileyo we-UPS ulungiswa, ukuseta i-bypass ngesandla kuqinisekisa umbane oqhelekileyo wezixhobo zomthwalo. Xa umsebenzi wokulungisa ugqityiwe, umbane we-UPS uqaliswa kwakhona, kwaye umbane we-UPS ujika ube ngumsebenzi oqhelekileyo.
4. ibhetri yokugcina
Xa i-mains ingasebenzi kakuhle, i-UPS iya kuguqula umbane othe ngqo ogcinwe kwibhetri ube ngumbane otshintshanayo. Ngeli xesha, igalelo le-inverter liya kunikezelwa yipakethi yebhetri, kwaye i-inverter iya kuqhubeka nokubonelela ngombane kwaye inikezele ngomthwalo oza kuqhubeka nokuwusebenzisa ukufezekisa umsebenzi wombane oqhubekayo.
Ngasentla kukho udidi lombane ongenakuqhekeka we-UPS, umbane we-UPS sisixhobo esikhethekileyo sombane esisetyenziselwa ukuqinisekisa ukhuseleko lwezixhobo ze-elektroniki. Xa izixhobo eziphambili zisebenza ngendlela eqhelekileyo, zinokudlala indima yokuzinzisa uxinzelelo, ukuze kuqinisekiswe ukhuseleko lombane, ukuba izixhobo eziphambili zinqanyulwe, kubekho ingozi yokusilela kombane, inokuguqula amandla ombane okuqala abe lixabiso eliqhelekileyo levolthi yezixhobo eziphambili ukuze inike umbane ongxamisekileyo.
