Impahla kagesi engaphazamiseki ye-UPS isho okokusebenza okuphakela ugesi okungeke kuphazanyiswe ukuphela kukagesi kwesikhashana, okungahlala kuhlinzeka ngamandla ekhwalithi ephezulu, futhi kuvikele ngempumelelo amathuluzi anembayo.Igama eligcwele Uhlelo Lwamandla Angaphazamiseki.Iphinde ibe nomsebenzi wokusimamisa i-voltage, efana ne-voltage stabilizer.
Ngokwezimiso eziyisisekelo zohlelo lokusebenza, i-UPS iyidivayisi yokuvikela amandla enedivayisi yokugcina amandla, i-inverter njengengxenye eyinhloko, kanye nokukhishwa kwamafrikhwensi okuzinzile.Ikakhulukazi yakhiwe i-rectifier, ibhethri, i-inverter kanye ne-static switch.1) Isilungisi: Isilungisisi yidivayisi yokulungisa, okumane kuyidivayisi eguqula i-alternating current (AC) ibe yamanje eqondile (DC).Inemisebenzi emibili eyinhloko: okokuqala, ukuguqula i-alternating current (AC) ibe yamanje eqondile (DC), ehlungwayo futhi inikezwe umthwalo, noma ku-inverter;okwesibili, ukuhlinzeka nge-voltage yokushaja ebhethrini.Ngakho-ke, futhi isebenza njengeshaja ngesikhathi esifanayo;
2) Ibhethri: Ibhethri iyisisetshenziswa esisetshenziswa yi-UPS ukugcina amandla kagesi.Yakhiwe ngamabhethri amaningana axhunywe ochungechungeni, futhi umthamo wayo unquma isikhathi ozogcina ukukhishwa (ukunikezwa kwamandla).Imisebenzi yayo esemqoka yilena: 1. Uma amandla okuhweba esejwayelekile, aguqula amandla kagesi abe amandla amakhemikhali futhi awagcine ngaphakathi kwebhethri.2 Uma amapayipi amakhulu ehluleka, guqula amandla amakhemikhali abe amandla kagesi futhi uwanikeze inverter noma umthwalo;
3) I-Inverter: Ngokwemigomo ye-layman, i-inverter iyithuluzi eliguqula i-direct current (DC) ibe i-alternating current (AC).Iqukethe ibhuloho le-inverter, i-logic yokulawula kanye nesifunda sokuhlunga;
4) Iswishi emile: Iswishi emile, eyaziwa nangokuthi iswishi emile, iyiswishi engathinteki.Kuyiswishi ye-AC eyakhiwe ngama-thyristors amabili (SCR) ekuxhumekeni okuphambene okuphambene.Ukuvala nokuvulwa kwayo kulawulwa isilawuli esinengqondo.ukulawula.Kunezinhlobo ezimbili: uhlobo lokuguqulwa kanye nohlobo oluhambisanayo.I-switch yokudlulisa isetshenziswa kakhulu ezinhlelweni zokuphakelwa kwamandla ezindlela ezimbili, futhi umsebenzi wayo ukubona ukushintsha okuzenzakalelayo ukusuka kwesinye isiteshi ukuya kwesinye;ukushintshwa kohlobo oluhambisanayo kusetshenziselwa ikakhulukazi ama-inverter afanayo namandla okuhweba noma ama-inverters amaningi.
I-UPS ihlukaniswe izigaba ezintathu: uhlobo lwesipele, uhlobo lwe-inthanethi kanye nohlobo olusebenzisanayo lwe-inthanethi ngokuya ngesimiso sokusebenza.
Phakathi kwazo, evame ukusetshenziswa kakhulu i-UPS eyisipele, enemisebenzi eyisisekelo nebalulekile ye-UPS efana nokulawulwa kwamandla kagesi okuzenzakalelayo, ukuvikela ukwehluleka kwamandla, njll. Nakuba ngokuvamile kunesikhathi sokuguqulwa esingaba ngu-10ms, ukuphuma kwamandla e-AC i-inverter iyigagasi eliyisikwele esikhundleni segagasi lesikwele.I-Sine wave, kodwa ngenxa yesakhiwo sayo esilula, intengo ephansi nokuthembeka okuphezulu, isetshenziswa kabanzi kuma-microcomputers, ama-peripherals, imishini ye-POS neminye imikhakha.
I-UPS eku-inthanethi inesakhiwo esiyinkimbinkimbi, kodwa inokusebenza okuphelele futhi ingaxazulula zonke izinkinga zokuhlinzekwa kwamandla.Isibonelo, uchungechunge lwe-PS olunezindlela ezine, isici salo esimangalisayo ukuthi lungakwazi ngokuqhubekayo ukukhipha igagasi elihlanzekile le-sine elishintshashintshayo lamanje elinokuphazamiseka okunguziro, futhi lingaxazulula zonke izinkinga ezifana nokuphakama, ama-surges, nama-frequency drifts.Izinkinga zamandla;ngenxa yotshalomali olukhulu oludingekayo, imvamisa isetshenziswa ezindaweni ezinezidingo eziqinile zamandla njengamathuluzi abalulekile nezikhungo zenethiwekhi.
Uma kuqhathaniswa nohlobo lokusekelayo, i-UPS esebenzisanayo eku-inthanethi inomsebenzi wokuhlunga, ikhono eliqinile lokulwa nokuphazamiseka kwamapayipi amakhulu, isikhathi sokuguqula singaphansi kwama-4ms, futhi okukhiphayo kwe-inverter kuyigagasi le-analog sine, ngakho-ke ingahlonyiswa ngemishini yenethiwekhi enjalo. njengamaseva namarutha, noma asetshenziswa ezindaweni ezinemvelo enzima kagesi.
Ukunikezwa kukagesi okungaphazamiseki manje sekusetshenziswa kabanzi: ezimayini, emkhathini, embonini, ezokuxhumana, ezokuvikela kuzwelonke, izibhedlela, amatheminali ebhizinisi lamakhompiyutha, amaseva enethiwekhi, amathuluzi enethiwekhi, okokugcina idatha amasistimu okukhanyisa ezimo eziphuthumayo ze-UPS, ujantshi, ezokuthutha, ugesi. izitshalo, Iziteshi ezincane, izimboni zamandla enuzi, amasistimu ama-alamu okuphepha komlilo, amasistimu okuxhumana okungenazintambo, amaswishi alawulwa uhlelo, ezokuxhumana eziphathwayo, izinto zokuguqula amandla esitoreji samandla elanga, izinto zokulawula kanye nezinhlelo zayo zokuvikela izimo eziphuthumayo, amakhompyutha omuntu siqu neminye imikhakha.
