Zida zamagetsi za UPS zosasunthika zimatanthawuza zida zamagetsi zomwe sizidzasokonezedwa ndi kuzimitsa kwanthawi yochepa, zimatha kupereka mphamvu zapamwamba nthawi zonse, ndikuteteza bwino zida zolondola.Dzina lonse la Uninterruptable Power System.Ilinso ndi ntchito yokhazikika yamagetsi, yofanana ndi voltage stabilizer.
Pankhani ya mfundo zoyambira zogwiritsira ntchito, UPS ndi chipangizo choteteza mphamvu chokhala ndi chipangizo chosungira mphamvu, inverter monga gawo lalikulu, komanso kutulutsa pafupipafupi kokhazikika.Amapangidwa makamaka ndi rectifier, batri, inverter ndi static switch.1) Wokonzanso: Wokonzanso ndi chipangizo chowongolera, chomwe chimangokhala chipangizo chomwe chimatembenuza magetsi osinthira (AC) kukhala amakono (DC).Ili ndi ntchito ziwiri zazikulu: choyamba, kutembenuza alternating current (AC) kuti ikhale yolunjika (DC), yomwe imasefedwa ndikuperekedwa ku katundu, kapena ku inverter;chachiwiri, kupereka voteji kwa batire.Chifukwa chake, imagwiranso ntchito ngati chojambulira nthawi yomweyo;
2) Battery: Batire ndi chipangizo chogwiritsidwa ntchito ndi UPS kusunga mphamvu zamagetsi.Amapangidwa ndi mabatire angapo olumikizidwa motsatizana, ndipo mphamvu yake imatsimikizira nthawi yomwe idzasungire kutulutsa (magetsi).Ntchito zake zazikulu ndi izi: 1. Pamene mphamvu yamalonda ili yabwino, imasintha mphamvu yamagetsi mu mphamvu ya mankhwala ndikuyisunga mkati mwa batri.2 Ma mains akalephera, sinthani mphamvu zamagetsi kukhala mphamvu zamagetsi ndikuzipereka kwa inverter kapena katundu;
3) Inverter: M'mawu a layman, inverter ndi chipangizo chomwe chimatembenuza Direct current (DC) kukhala alternating current (AC).Amakhala ndi inverter mlatho, kuwongolera logic ndi fyuluta dera;
4) Kusintha kwa Static: Kusintha kwa static, komwe kumadziwikanso kuti static switch, ndikusintha kosalumikizana.Ndi chosinthira cha AC chopangidwa ndi ma thyristors awiri (SCR) molumikizana motsatana.Kutseka ndi kutsegula kwake kumayendetsedwa ndi wolamulira wamalingaliro.kulamulira.Pali mitundu iwiri: kutembenuka mtundu ndi kufanana mtundu.Kusinthana kosinthira kumagwiritsidwa ntchito makamaka pamakina amagetsi anjira ziwiri, ndipo ntchito yake ndikuzindikira kusintha kuchokera ku njira imodzi kupita ku ina;chosinthira chamtundu wofananira chimagwiritsidwa ntchito makamaka pama inverters ofanana ndi mphamvu zamalonda kapena ma inverters angapo.
UPS imagawidwa m'magulu atatu: mtundu wosunga zobwezeretsera, mtundu wapaintaneti ndi mtundu wolumikizana pa intaneti malinga ndi mfundo yogwirira ntchito.
Pakati pawo, omwe amagwiritsidwa ntchito kwambiri ndi UPS yosunga zobwezeretsera, yomwe ili ndi ntchito zoyambira komanso zofunika kwambiri za UPS monga kuwongolera voteji, chitetezo champhamvu, ndi zina zambiri. inverter ndi square wave m'malo mwa square wave.Sine wave, koma chifukwa cha mawonekedwe ake osavuta, otsika mtengo komanso odalirika kwambiri, amagwiritsidwa ntchito kwambiri mu ma microcomputer, zotumphukira, makina a POS ndi magawo ena.
UPS yapaintaneti ili ndi mawonekedwe ovuta kwambiri, koma imakhala ndi magwiridwe antchito abwino ndipo imatha kuthana ndi mavuto onse amagetsi.Mwachitsanzo, mndandanda wa njira zinayi za PS, chodabwitsa chake ndikuti imatha kutulutsa mosalekeza ma wave sine wave alternating current ndi kusokoneza zero, ndipo imatha kuthetsa mavuto onse monga nsonga, mafunde, ndi mafunde pafupipafupi.Mavuto a mphamvu;chifukwa cha ndalama zazikulu zomwe zimafunikira, nthawi zambiri zimagwiritsidwa ntchito m'malo omwe ali ndi mphamvu zofunikira kwambiri monga zida zazikulu ndi malo ochezera.
Poyerekeza ndi mtundu wa zosunga zobwezeretsera, UPS yolumikizana pa intaneti ili ndi ntchito yosefera, kuthekera kolimba kotsutsana ndi kusokoneza kwa mains, nthawi yotembenuka ndi yochepera 4ms, ndipo inverter linanena bungwe ndi analogi sine wave, kotero imatha kukhala ndi zida zama network monga monga ma seva ndi ma routers, kapena kugwiritsidwa ntchito m'malo omwe ali ndi magetsi ovuta.
Mphamvu zosasunthika tsopano zikugwiritsidwa ntchito kwambiri mu: migodi, zakuthambo, mafakitale, mauthenga, chitetezo cha dziko, zipatala, malo opangira malonda apakompyuta, ma seva ochezera, zida zosungiramo deta, zida zosungiramo deta UPS uninterruptible power supply emergency system lights, njanji, kutumiza, mayendedwe, mphamvu zomera, Ma substations, magetsi a nyukiliya, makina otetezera moto, njira zoyankhulirana zopanda zingwe, masinthidwe oyendetsedwa ndi mapulogalamu, mauthenga a m'manja, zida zosinthira mphamvu za dzuwa zosungiramo mphamvu, zipangizo zoyendetsera ntchito ndi machitidwe ake otetezera mwadzidzidzi, makompyuta aumwini ndi zina.
