Ndi mitundu iti ya magetsi a UPS omwe amagawidwa motsatira mfundo yogwirira ntchito? Mphamvu yamagetsi ya UPS yosasinthika imagawidwa m'magulu atatu: zosunga zobwezeretsera, za pa intaneti ndi za pa intaneti. Kugwira ntchito kwa magetsi a UPS kuyambira pamwamba mpaka pansi ndi: kusintha kawiri pa intaneti, zosunga zobwezeretsera pa intaneti, mtundu wa zosunga zobwezeretsera. Mtengo nthawi zambiri umagwirizana ndi magwiridwe antchito. Kumvetsetsa momwe magetsi a UPS amagwirira ntchito kungathandize kuteteza bwino magetsi a UPS pakukonza tsiku ndi tsiku.
Ndi mitundu iti yamagetsi a UPS omwe amagawidwa malinga ndi mfundo yogwirira ntchito?
Mphamvu ya UPS ndi imene nthawi zambiri timaitcha kuti UPS uninterruptible power supply. Mphamvu ya UPS imagwira ntchito m'njira zitatu izi:
1. Mphamvu yamagetsi ya UPS yosungira imaperekedwa mwachindunji kuchokera ku main kupita ku katundu pamene main ndi abwinobwino. Pamene main apitirira kuchuluka kwake kogwirira ntchito kapena kulephera kwa magetsi, magetsi amasinthidwa kukhala inverter ya batri kudzera mu switch yosinthira. Imadziwika ndi kapangidwe kosavuta, voliyumu yaying'ono komanso mtengo wotsika, koma kuchuluka kwa magetsi olowera ndi kochepa, magetsi otulutsa ndi okhazikika komanso kulondola kwake ndi kochepa, pali nthawi yosinthira, ndipo mawonekedwe a mafunde otulutsa nthawi zambiri amakhala a sikweya.
Mphamvu ya UPS yotulutsa sine wave yosungira: mphamvu ya unit ikhoza kukhala 0.25KW ~ 2KW. Pamene main mains asintha pakati pa 170V ~ 264V, UPS imapitirira 170V ~ 264V.
2. Mphamvu yamagetsi ya UPS yolumikizana pa intaneti imaperekedwa mwachindunji kuchokera ku main main kupita ku katundu pamene main main ndi abwinobwino. Pamene main main ndi otsika kapena okwera, mzere wowongolera mphamvu yamkati wa UPS umatuluka. Mphamvu yamagetsi ya UPS ikasintha kapena kuzimitsidwa, mphamvu yamagetsi imasinthidwa kukhala inverter ya batri kudzera mu switch yosinthira. Imadziwika ndi kuchuluka kwa magetsi olowera, phokoso lotsika, voliyumu yaying'ono ndi zina, koma palinso nthawi yosinthira.
Mphamvu yamagetsi ya UPS yolumikizirana pa intaneti ili ndi ntchito yosefera, mphamvu yolimbana ndi kusokoneza kwa mzinda, nthawi yosinthira yochepera 4ms, ndipo kutulutsa kwa inverter ndi analog sine wave, kotero imatha kukhala ndi ma seva, ma rauta ndi zida zina za netiweki, kapena kugwiritsidwa ntchito m'malo omwe ali ndi mphamvu yamagetsi yovuta.
3. Mphamvu yamagetsi ya UPS pa intaneti, pamene ma mains ali abwinobwino, ma mains amapereka mphamvu ya DC ku inverter kuti igwire ntchito; pamene mains ali osazolowereka, inverter imayendetsedwa ndi batri, ndipo inverter nthawi zonse imakhala yogwira ntchito kuti iwonetsetse kuti mphamvu yamagetsi ikuyenda bwino. Imadziwika ndi mphamvu yamagetsi yolowera, palibe nthawi yosinthira komanso mphamvu yamagetsi yotuluka komanso kulondola kwakukulu, makamaka yoyenera mphamvu yamagetsi, koma mtengo wake ndi wokwera. Pakadali pano, mphamvu yamagetsi ya UPS yokhala ndi mphamvu yoposa 3 KVA ndi mphamvu yamagetsi ya UPS pa intaneti.
Kapangidwe ka mphamvu ya UPS pa intaneti ndi kovuta, koma kali ndi magwiridwe antchito abwino kwambiri ndipo kamatha kuthetsa mavuto onse amagetsi, monga PS series ya njira zinayi, yomwe imatha kutulutsa mafunde oyera a sine AC mosalekeza popanda kusokoneza chilichonse, ndipo imatha kuthetsa mavuto onse amagetsi monga kukwera, kukwera kwa mafunde, kusuntha kwa ma frequency; yomwe imafuna ndalama zambiri, nthawi zambiri imagwiritsidwa ntchito m'malo ovuta amagetsi a zida zofunika kwambiri komanso malo olumikizirana ndi maukonde.
Njira zinayi zogwirira ntchito za UPS UPS
Kutengera momwe zinthu zilili, magetsi a UPS osasokonezedwa amatha kusinthidwa kukhala njira zinayi zosiyana zogwirira ntchito: njira yogwirira ntchito yanthawi zonse, njira yogwirira ntchito ya batri, njira yogwirira ntchito ya bypass ndi njira yokonzera ya bypass.
1. ntchito yachibadwa
Muzochitika zachizolowezi, mfundo yopezera mphamvu ya UPS yosasokoneza magetsi ndikusintha mphamvu yolowera ya AC kukhala mphamvu yolunjika pamene mzinda uli wabwinobwino, kenako n’kuchaja batri kuti igwiritse ntchito kusokoneza mphamvu; ziyenera kutsindika kuti makina operekera mphamvu a UPS sagwira ntchito ngati magetsi alephera, ngati magetsi ali otsika kwambiri kapena okwera kwambiri, kuphulika kwadzidzidzi komwe kungakhudze mphamvu yamagetsi yanthawi zonse ya zida, makina a UPS ali mu mkhalidwe wogwirira ntchito kuti apereke magetsi okhazikika komanso oyera pazida zonyamula katundu.
2. Ntchito yodutsa
Pamene ma main ali abwinobwino, pamene mphamvu ya UPS ikuwoneka yochulukirapo, lamulo la bypass (pamanja kapena lodzipangira), inverter ikatentha kwambiri kapena makina akalephera kugwira ntchito, mphamvu ya UPS nthawi zambiri imatembenuza inverter output kuti ikhale yodutsa, kutanthauza kuti, yoperekedwa mwachindunji ndi ma main. Popeza gawo la pafupipafupi la UPS liyenera kukhala lofanana ndi ma main frequency panthawi ya bypass, ukadaulo wa phase lock synchronization umagwiritsidwa ntchito kuti zitsimikizire kuti mphamvu ya UPS ikugwirizana ndi ma main frequency.
3. Kukonza njira yodutsa
Pamene magetsi a UPS akonzedwa, kukhazikitsa njira yodutsa pamanja kumatsimikizira kuti magetsi a zipangizo zonyamulira katundu akuyenda bwino. Ntchito yokonza ikatha, magetsi a UPS amayambiranso, ndipo magetsi a UPS amayambiranso kugwira ntchito bwino.
4. batire yosungira
Main main akayamba kusokonekera, UPS idzasintha mphamvu yolunjika yomwe imasungidwa mu batire kukhala mphamvu yosinthira. Panthawiyi, cholowetsa cha inverter chidzaperekedwa ndi batire, ndipo inverter idzapitiriza kupereka mphamvu ndikupereka katundu kuti apitirize kugwiritsa ntchito kuti akwaniritse ntchito ya magetsi osalekeza.
Pamwambapa pali gulu la magetsi a UPS omwe sakutha, magetsi a UPS ndi chipangizo chapadera chomwe chimagwiritsidwa ntchito kuonetsetsa kuti zipangizo zamagetsi zili bwino. Pamene magetsi akugwira ntchito bwino, amatha kukhala ndi udindo wokhazikitsa mphamvu, kuti atsimikizire kuti magetsi ali bwino, ngati magetsi atsekedwa, pachitika ngozi ya kulephera kwa magetsi, amatha kusintha mphamvu yamagetsi yoyambirira kukhala mphamvu yamagetsi yamagetsi wamba kuti apereke magetsi mwadzidzidzi.
