Ndi mitundu yanji yamagetsi a UPS omwe amagawidwa molingana ndi mfundo yogwirira ntchito? UPS osasokoneza magetsi amagawidwa m'magulu atatu: zosunga zobwezeretsera, zapaintaneti komanso UPS yolumikizana pa intaneti. Kuchita kwa magetsi a UPS kuchokera pamwamba mpaka pansi ndi: kusintha kwapawiri pa intaneti, kuyanjana pa intaneti, mtundu wosunga zobwezeretsera. Mtengo nthawi zambiri umakhala wolingana ndi momwe zimagwirira ntchito. Kumvetsetsa momwe magetsi a UPS amagwirira ntchito kungathandize kuteteza magetsi a UPS pakukonza tsiku ndi tsiku.
Ndi mitundu yanji yamagetsi a UPS omwe amagawidwa molingana ndi mfundo yogwirira ntchito?
Mphamvu yamagetsi ya UPS ndi yomwe nthawi zambiri timayitcha kuti UPS yosasokoneza magetsi. Mphamvu ya UPS imagwira ntchito m'njira zitatu izi:
1. Kusungirako magetsi kwa UPS kumaperekedwa mwachindunji kuchokera ku mains kupita ku katundu pamene mains ali abwinobwino. Pamene mains adutsa momwe amagwirira ntchito kapena kulephera kwa mphamvu, magetsi amasinthidwa kukhala inverter ya batri kudzera pakusintha kosinthira. Amadziwika ndi mawonekedwe osavuta, voliyumu yaying'ono komanso mtengo wotsika, koma kuchuluka kwa magetsi olowera ndi opapatiza, voteji yomwe imatulutsa imakhala yosasunthika ndipo kulondola kwake ndikosauka, pali nthawi yosinthira, ndipo mawonekedwe otulutsa nthawi zambiri amakhala masikweya mafunde.
Zosunga zobwezeretsera sine wave linanena bungwe UPS mphamvu: kutulutsa kwagawo kungakhale 0.25KW ~ 2KW. Ma mains akasintha pakati pa 170V ~ 264V, UPS imapitilira 170V ~ 264V.
2. Mphamvu yamagetsi ya UPS yolumikizana pa intaneti imaperekedwa mwachindunji kuchokera ku mains kupita ku katundu pomwe mains ali abwinobwino. Pamene mains ali otsika kapena okwera, mzere wamagetsi wamkati wa UPS umatuluka. Mphamvu yamagetsi ya UPS ikakhala yachilendo kapena yazimitsidwa, magetsi amasinthidwa kukhala chosinthira batire kudzera pa chosinthira. Amadziwika ndi osiyanasiyana athandizira voteji osiyanasiyana, phokoso otsika, voliyumu yaing'ono ndi makhalidwe ena, koma palinso nthawi kusintha.
Mphamvu yamagetsi ya UPS yapaintaneti imakhala ndi ntchito yosefera, mphamvu yolimbana ndi mizinda yolimbana ndi mizinda, kutembenuka kwanthawi yochepera 4ms, ndipo kutulutsa kwa inverter ndi analogi sine wave, kotero imatha kukhala ndi ma seva, ma routers ndi zida zina zamaukonde, kapena kugwiritsidwa ntchito m'malo omwe ali ndi mphamvu yamphamvu.
3. Mphamvu yamagetsi ya UPS pa intaneti, pamene mains ali abwinobwino, mains amapereka magetsi a DC ku inverter ku katundu; pamene mains ndi osadziwika, inverter imayendetsedwa ndi batri, ndipo inverter nthawi zonse imakhala yogwira ntchito kuti iwonetsetse kutulutsa kosasunthika. Amadziwika ndi osiyanasiyana athandizira voteji osiyanasiyana, kwenikweni palibe kusintha nthawi ndi linanena bungwe voteji kukhazikika ndi kulondola mkulu, makamaka oyenera mkulu magetsi amafuna, koma mtengo wachibale ndi mkulu. Pakadali pano, magetsi a UPS okhala ndi mphamvu zokulirapo kuposa 3 KVA ndi pafupifupi magetsi onse a UPS pa intaneti.
Mapangidwe a mphamvu ya UPS pa intaneti ndi ovuta, koma ali ndi ntchito yabwino ndipo amatha kuthetsa mavuto onse amagetsi, monga njira zinayi za PS, zomwe zimatha kutulutsa koyera sine wave AC mosalekeza pa kusokonezeka kwa ziro, ndipo zimatha kuthetsa mavuto onse a mphamvu monga spike, surge, frequency drift; kufuna ndalama lalikulu, nthawi zambiri ntchito wovuta mphamvu chilengedwe zida zofunika ndi pakati maukonde.
Njira zinayi zogwirira ntchito za UPS UPS
Kutengera momwe amagwiritsidwira ntchito, magetsi osasunthika a UPS amatha kusinthidwa kukhala mitundu inayi yogwirira ntchito: mawonekedwe ogwirira ntchito wamba, mawonekedwe a batire, njira yolambalala ndikuwongolera.
1. ntchito yachibadwa
Nthawi zonse, mfundo yoperekera mphamvu ya UPS yosasokoneza magetsi ndikusintha mphamvu yolowera ya AC kuti iwongolere pano pomwe mzinda uli wabwinobwino, ndiyeno kulipiritsa batire kuti igwiritse ntchito kusokoneza mphamvu; ziyenera anatsindika kuti UPS dongosolo magetsi sagwira ntchito pamene kulephera mphamvu, ngati voteji ndi otsika kwambiri kapena apamwamba kwambiri, yomweyo mkangano kukhudza khalidwe mphamvu ya ntchito yachibadwa ya zida, dongosolo UPS ndi mu boma ntchito kupereka khola ndi woyera magetsi kwa katundu katundu.
2. Ntchito yolambalala
Pamene mains ali abwinobwino, mphamvu ya UPS ikawoneka yodzaza, lamulo lodutsa (pamanja kapena zodziwikiratu), kutenthedwa kwa inverter kapena kulephera kwa makina, mphamvu ya UPS nthawi zambiri imatembenuza zotulutsa za inverter kuti zilambalale, ndiye kuti, zimaperekedwa mwachindunji ndi mains. Popeza gawo la ma frequency a UPS liyenera kukhala lofanana ndi ma frequency a mains panthawi yodutsa, ukadaulo wolumikizira gawo lotsekera umatengedwa kuti zitsimikizire kuti kutulutsa mphamvu kwa UPS kumalumikizidwa ndi ma frequency a mains.
3. Kukonza bypass
Mphamvu yamagetsi yadzidzidzi ya UPS ikakonzedwa, kuyika njira yodutsa pamanja kumatsimikizira mphamvu yanthawi zonse ya zida zonyamula katundu. Ntchito yokonza ikamalizidwa, magetsi a UPS amayambiranso, ndipo magetsi a UPS amasanduka ntchito yanthawi zonse.
4. batire zosunga zobwezeretsera
Ma mains akakhala achilendo, UPS imatembenuza magetsi omwe amasungidwa mu batire kukhala alternating current. Panthawiyi, kulowetsedwa kwa inverter kudzaperekedwa ndi paketi ya batri, ndipo inverter idzapitiriza kupereka mphamvu ndikupereka katundu kuti apitirize kugwiritsa ntchito kuti akwaniritse ntchito yowonjezera mphamvu.
Pamwambapa ndikugawika kwa magetsi osasunthika a UPS, magetsi a UPS kwenikweni ndi chida chapadera chomwe chimagwiritsidwa ntchito kuonetsetsa chitetezo cha zida zamagetsi. Ma mains akamagwira ntchito bwino, amatha kuchitapo kanthu kuti akhazikitse kupanikizika, kuti atsimikizire chitetezo chamagetsi, ngati mains adulidwa, pali ngozi yakulephera kwamagetsi, amatha kusintha mphamvu yamagetsi yoyambira kukhala yamagetsi wamba ya mains kuti apereke magetsi mwadzidzidzi.
