Zeziphi iintlobo zobonelelo lwamandla e-UPS ezihlelwa ngokomgaqo wokusebenza? Unikezelo lwamandla olungaphazamisekiyo lwe-UPS lwahlulwe lwaziindidi ezintathu: i-backup, i-intanethi kunye ne-UPS esebenzisanayo kwi-intanethi. Ukusebenza konikezelo lwamandla e-UPS ukusuka phezulu ukuya ezantsi kukuba: ukuguqulwa kabini kwi-intanethi, ukusebenzisana kwe-intanethi, uhlobo lokugcina. Ixabiso ngokubanzi lilingana nokusebenza. Ukuqonda indlela yokusebenza yonikezelo lwamandla e-UPS kunokunceda ukukhusela ngcono unikezelo lwamandla e-UPS ekugcinweni kwemihla ngemihla.
Zeziphi iintlobo zobonelelo lwamandla e-UPS ezihlelwa ngokomgaqo wokusebenza?
Ubonelelo lwamandla e-UPS yinto esihlala siyibiza ngokuba yi-UPS engenakuphazamiseka unikezelo lwamandla. Ubonelelo lwamandla e-UPS lusebenza kwezi ndlela zintathu zilandelayo:
1. I-backup UPS unikezelo lwamandla lunikezelwa ngokuthe ngqo ukusuka kwiinqununu ukuya kumthwalo xa umbane uqhelekileyo. Xa i-mains idlula umda wayo wokusebenza okanye ukusilela kombane, unikezelo lwamandla luguqulelwa kwi-inverter yebhetri ngokusebenzisa iswitshi yokuguqula. Iphawulwa ngolwakhiwo olulula, umthamo omncinci kunye nexabiso eliphantsi, kodwa uluhlu lwamandla ombane lumxinwa, amandla ombane aphumayo azinzile kwaye ukuchaneka akubikho, kukho ixesha lokutshintsha, kwaye imveliso ye-wave wave ngokubanzi isikwere samaza.
I-backup sine wave output ye-UPS yamandla: iyunithi yemveliso ingaba yi-0.25KW ~ 2KW. Xa i-mains itshintsha phakathi kwe-170V ~ 264V, i-UPS idlula i-170V ~ 264V.
2. Umbane osebenzisanayo we-UPS we-intanethi unikezelwa ngokuthe ngqo ukusuka kwiinqununu ukuya kumthwalo xa umbane uqhelekileyo. Xa i-mains iphantsi okanye iphezulu, umgca wokulawula umbane wangaphakathi we-UPS uphuma. Xa unikezelo lwamandla lwe-UPS lungaqhelekanga okanye lucinyiwe, unikezelo lwamandla luguqulelwa kwi-inverter yebhetri ngokusebenzisa iswitshi yokuguqula. Ibonakaliswe ngoluhlu olubanzi lwegalelo lombane, ingxolo ephantsi, umthamo omncinci kunye nezinye iimpawu, kodwa kukho ixesha lokutshintsha.
Umbane osebenza kwi-intanethi we-UPS unomsebenzi wokucoca, amandla okuphazamisana nesixeko esinamandla, ixesha lokuguqula elingaphantsi kwe-4ms, kunye nemveliso ye-inverter yi-analog sine wave, ngoko inokuxhotyiswa ngeeseva, iirutha kunye nezinye izixhobo zenethiwekhi, okanye isetyenziswe kwiindawo ezine imo engqonge amandla.
3. Ukunikezelwa kombane we-UPS kwi-intanethi, xa i-mains iyinto eqhelekileyo, i-mains inika i-DC voltage kwi-inverter kumthwalo; xa i-mains ingaqhelekanga, i-inverter inikwe amandla yibhetri, kwaye i-inverter isoloko ikwimeko yokusebenza ukuqinisekisa ukukhutshwa okungaphazamisekiyo. Ibonakaliswe luluhlu olubanzi kakhulu lwegalelo lamandla ombane, ngokusisiseko akukho xesha lokutshintsha kunye nokuzinza kwamandla ombane kunye nokuchaneka okuphezulu, okufanelekileyo ngakumbi kwiimfuno zobonelelo lwamandla aphezulu, kodwa ixabiso elihambelanayo liphezulu. Okwangoku, unikezelo lwamandla lwe-UPS olunamandla amakhulu kune-3 KVA phantse yonke i-UPS yombane ekwi-intanethi.
Ulwakhiwo lwamandla e-UPS olukwi-Intanethi luntsonkothile, kodwa lusebenza ngokugqibeleleyo kwaye lunokusombulula zonke iingxaki zobonelelo lwamandla, njengeendlela ezine ze-PS uthotho, olukwaziyo ukuvelisa i-sine wave ecocekileyo ye-AC ngokuqhubekayo ngokuphazamiseka kwe-zero, kwaye inokusombulula zonke iingxaki zamandla njenge-spike. , ukunyuka, ukuhamba rhoqo; ifuna utyalo-mali olukhulu, idla ngokusetyenziswa kwimeko-bume enamandla yezixhobo ezibalulekileyo kunye neziko lothungelwano.
Iindlela ezine ze-UPS UPS yokusebenza
Ngokuxhomekeke kwimeko yokusetyenziswa, unikezelo lwamandla olungaphazamisekiyo lwe-UPS lunokuguqulwa kwiindlela ezine ezahlukeneyo zokusebenza: imowudi yokusebenza eqhelekileyo, imowudi yokusebenza kwebhetri, imowudi yokusebenza ye-bypass kunye nemodi yokugcinwa kwe-bypass.
1. ukusebenza okuqhelekileyo
Phantsi kweemeko eziqhelekileyo, umgaqo wonikezelo lwamandla we-UPS engaphazamisekiyo yenkqubo yonikezelo lwamandla kukuguqula amandla egalelo le-AC ukuba aqondise ngoku xa isixeko siqhelekile, aze ahlawule ibhetri ngokusetyenziswa kokuphazamiseka kwamandla; kufuneka kugxininiswe ukuba inkqubo yonikezelo lwamandla e-UPS ayisebenzi xa ukusilela kombane, ukuba i-voltage iphantsi kakhulu okanye iphezulu kakhulu, igqabhuka ngoko nangoko ukuchaphazela umgangatho wamandla okusebenza okuqhelekileyo kwesixhobo, inkqubo ye-UPS iyasebenza. urhulumente ukubonelela ngombane ozinzileyo nococekileyo wesixhobo somthwalo.
2. Ukusebenza kwe-bypass
Xa i-mains iyinto eqhelekileyo, xa amandla e-UPS ebonakala egqithisekile, umyalelo we-bypass (i-manual okanye i-othomathikhi), i-inverter overheating okanye ukusilela komatshini, amandla e-UPS ngokubanzi aguqula i-inverter output ukuba ikhuphe imveliso, oko kukuthi, ibonelelwe ngokuthe ngqo yimibhobho. Ekubeni i-UPS ye-frequency ye-frequency ye-UPS kufuneka ifane ne-frequency ye-mains ngexesha lokudlula, itekhnoloji yongqamaniso lokutshixa isigaba samkelwe ukuze kuqinisekiswe ukuba ukuphuma kwamandla e-UPS kudityaniswa kunye ne-frequency mains.
3. Ukugcinwa kwe-bypass
Xa umbane ongxamisekileyo we-UPS ulungiswa, ukubeka i-bypass ngesandla kuqinisekisa ukunikezelwa kwamandla okuqhelekileyo kwezixhobo zomthwalo. Xa umsebenzi wokugcinwa ugqityiwe, ukunikezelwa kombane we-UPS kuqalwa kwakhona, kwaye ukunikezelwa kwamandla e-UPS ajika ekusebenzeni okuqhelekileyo.
4. ibhetri yogcino
Nje ukuba umbane oyintloko ungaqhelekanga, i-UPS iya kuguqula umsinga othe ngqo ogcinwe kwibhetri ube ngumsinga otshintshanayo. Ngeli xesha, igalelo le-inverter liya kunikwa ipakethe yebhetri, kwaye i-inverter iya kuqhubeka inika amandla kunye nokubonelela ngomthwalo wokuqhubeka nokusebenzisa ukufezekisa umsebenzi wokunikezelwa kwamandla okuqhubekayo.
Ngaphezulu kuluhlu lwe-UPS yonikezelo lwamandla olungaphazamisekiyo, unikezelo lwamandla lwe-UPS ngokwenene sisixhobo esikhethekileyo sokubonelela ngombane esisetyenziselwa ukuqinisekisa ukhuseleko lwezixhobo zombane. Xa i-mains isebenza ngokuqhelekileyo, inokudlala indima yokuzinzisa uxinzelelo, ukuze kuqinisekiswe ukhuseleko lombane, ukuba umbane ucinyiwe, kukho ingozi yokungaphumeleli kombane, inokuguqula amandla ombane asekuqaleni kumbane oqhelekileyo. ixabiso lombane ukubonelela ngombane ongxamisekileyo.
