Ungayikhetha kanjani i-UPS Power Supply efanele yesisetshenziswa sakho? 

Amaphutha amaningi okuthenga e-UPS enzeka ngaphambi kokufakwa: umthamo mncane kakhulu, i-topology ayifani nomthwalo, isikhathi sokulondoloza asiqondwa kahle, noma umkhiqizo ukhethwa kuphela ngentengo. Ukunikezwa kwamandla okuhle kwe-UPS kufanele kufane nomthwalo wangempela, indawo yegridi, okuqondiwe kwesikhathi sokusebenza, izimo zokufaka, nohlelo lokunwetshwa kwesikhathi esizayo.

Lo mhlahlandlela uchaza indlela esebenzayo yokukhetha i-UPS yabasebenzisi basekhaya, amahhovisi, amagumbi okuqapha, amagumbi eseva, okokusebenza kwasembonini, okokusebenza kwezokwelapha, nezinye izinhlelo zokusebenza zamandla ezibalulekile.

Isinyathelo 1: Bala Amandla Adingekayo

Ukukhetha kwe-UPS kuqala ngokubala komthwalo. Izilinganiso ezimbili ezibalulekile ama-watts (W) kanye ne-volt-amperes (VA). Ama-Watts achaza amandla angempela asetshenziswa imishini. I-VA ichaza umthamo wamandla obonakalayo. Ama-nameplates e-UPS ngokuvamile amakwa ku-VA noma ku-kVA, kodwa isilinganiso se-watt kufanele futhi sihlolwe.

Ifomula yokuhlela elula ithi:

I-VA edingekayo = Isamba somthwalo wama-watts/isici samandla

Uma isici samandla esiqondile singaziwa, izilinganiso eziningi zangaphambili zisebenzisa isici sokuhlela esilondolozayo. Isibonelo, uma ikhompuyutha nokuqapha kudla cishe u-300 W futhi isici sokuhlela singu-0.7:

300 W / 0.7 = cishe 428 VA

Kulokhu, i-500 VA noma 600 VA UPS ingase ifanelekele ukwenza isipele esifushane esiyisisekelo, inqobo nje uma isilinganiso se-UPS watt siphinde sisekele umthwalo.

Ngezinhlelo zokusebenza ezichwepheshile, linganisa umthwalo wangempela noma sebenzisa idatha ye-nameplate yedivayisi, bese uqinisekisa kokubili umthamo we-VA kanye ne-watt.

Isinyathelo sesi-2: I-Reserve Capacity Margin

I-UPS akufanele ikhethwe ukuthi isebenze unomphela ekulayisheni okungu-100%. Ukusebenza kwesikhathi eside kokulayisha okugcwele kungabangela ama-alamu avamile, kunciphise ukwethembeka, kukhawulele ukunwetshwa okuzayo, futhi kungashiyi indawo yokuqala yamanje.

Emaphrojekthini amaningi, indlela engokoqobo iwukugcina cishe u-20% kuya ku-30%. Ekufakeni okubalulekile, umkhawulo ungase ube phezulu kuye ngezidingo zokuphinda zisetshenziswe, ukusebenza kwejeneretha, okuqondiwe kwesikhathi sokusebenza kwebhethri, kanye nokukhula komthwalo wesikhathi esizayo.

Isinyathelo sesi-3: Khetha i-UPS Topology ngohlelo lokusebenza

Izinhlelo zokusebenza ezihlukene zidinga amazinga ahlukene okuvikela.

I-UPS Elindile Yemithwalo Yasekhaya Neyisisekelo Yehhovisi

Imithwalo evamile ihlanganisa amakhompyutha edeskithophu, amarutha, amamodemu optical, amaphrinta amancane, namadivayisi amancane okuqapha.

Izinzuzo:

• Izindleko eziphansi.
• Usayizi omncane.
• Ukusebenza ngokuthula.
• Ukufakwa okulula.
• Ifanele ukugcinwa kwedatha nokuvala shaqa ngendlela ehlelekile.

Imikhawulo:

• Ukulawulwa kwamandla kagesi okulinganiselwe.
• Ukudluliswa kwebhethri kwenzeka kuphela lapho amandla okokufaka ehluleka noma ephuma ngaphandle kwebanga.
• Ayifanele okokusebenza okunembayo noma izindawo zegridi ezingazinzile.

I-UPS Esebenzisanayo Yolayini Yamagumbi Okusebenzela Amancane Nokusetshenziswa Kwezentengiso Okulula

Imithwalo evamile ihlanganisa izinhlelo zokugada, amaseva amancane asehhovisi, okokusebenza kwe-POS, amatheminali ezimboni, namadivayisi asebenza ngokunemba ehhovisi.

Izinzuzo:

• Ukulawulwa okungcono kwamandla kagesi kunezinhlelo ezilindile.
• Ukusabela okusheshayo ekuguquguqukeni okuncane kwegridi.
• Izindleko ezilinganiselwe nokusebenza.
• Ifanele izindawo zokuhweba ezincane.

Imikhawulo:

• Akuyona inketho yokuqala yamaseva abalulekile kunjongo, amasistimu ezokwelapha, noma amagridi wezimboni aqinile.

I-Double-Conversion UPS eku-inthanethi Yemithwalo Ebucayi

Imithwalo evamile ihlanganisa amaseva esikhungo sedatha, amathuluzi ezokwelapha, okokusebenza okuzenzakalelayo kwemboni, okokusebenza kokuhlola ukunemba, amasistimu ezimo eziphuthumayo zomlilo, amatheminali ezezimali, namasistimu okulawula okukhiqiza.

Izinzuzo:

• Ukukhishwa kwe-inverter okuqhubekayo.
• Isikhathi sokudlulisa esingekho kubhethri.
• Ukukhishwa kwegagasi kwe-sine okuzinzile.
• Ukulawulwa kwamandla kagesi okunamandla nokuhlunga.
• Ukuvikeleka okungcono ngokumelene nama-surges, ama-sags, ukushintshashintsha kwefrikhwensi, nomsindo kagesi.

Okokusebenza okubalulekile, i-UPS eku-inthanethi imvamisa iyinketho ephephe kakhulu futhi esezingeni eliphezulu.

Isinyathelo sesi-4: Nquma Phakathi Kwesikhathi Sokusebenza Esijwayelekile kanye Nesikhathi Sokusebenza Esandisiwe

Isikhathi sokusebenza se-UPS sincike ekulayisheni okuxhunyiwe namandla ebhethri. Ungacabangi ukuthi isilinganiso se-kVA esikhulu ngokuzenzakalelayo sisho isikhathi eside sokulondoloza.

I-UPS Yebhethri Eyakhelwe Ngaphakathi Ejwayelekile

Isikhathi sokwenza isipele esijwayelekile sivamise ukwanela ukulondoloza idatha ephephile kanye nokuvala shaqa okuvamile. Le nketho ifanele ikhaya, ihhovisi, nezinto zokusebenza ezijwayelekile ezingadingi ukuthi ziqhubeke zisebenza isikhathi eside phakathi nokucima.

I-UPS Yesikhathi Sokusebenza Enwetshiwe Ngamabhethri Angaphandle

Amasistimu esikhathi sokusebenza awandisiwe asebenzisa amaphakethe ebhethri angaphandle noma amakhabethe ebhethri ukuze asekele amaminithi angu-30, ihora elingu-1, amahora angu-2, noma okuqondiwe okuyisipele okude. Afanele amakamelo amaseva, izinhlelo zokuqapha, izilawuli zezimboni, izinto zokusebenza ezingagadiwe, kanye nemithwalo ebaluleke kakhulu yebhizinisi.

Uma kudingeka isikhathi eside sokulondoloza, khetha i-UPS eyenzelwe amabhethri angaphandle. Ungashintshi i-UPS yebhethri eyakhelwe ngaphakathi ejwayelekile ngaphandle kwemvume yomkhiqizi.

Isinyathelo sesi-5: Qondanisa i-UPS Nendawo Yegridi

Isimo segridi sibalulekile.

Kumakhaya asemadolobheni azinzile kanye nezakhiwo zamahhovisi ezijwayelekile, amasistimu e-UPS asebenzisanayo anganele emithwalweni engabalulekile.

Emafekthri amadala, izindawo ezingaphansi kwedolobha, izindawo zokwakha, izifunda ezithandwa yiziphepho, noma izindawo ezinogesi ovamile oguquguqukayo, i-UPS eku-inthanethi ivamise ukuthandwa ngoba inikeza isimo samandla esiqinile.

Ukuze ucime ugesi njalo, khetha i-UPS yesikhathi sokusebenza enwetshiwe futhi ubale umthamo webhethri ngokusekelwe ekulayisheni kwangempela kanye nethagethi yesikhathi sokusebenza.

FAQ

Ngidinga muphi usayizi we-UPS?

Engeza i-wattage yangempela kanye ne-VA yayo yonke imithwalo ebucayi, bese ukhetha i-UPS esekela kokubili izilinganiso ngemajini efanelekile. Kumaphrojekthi ochwepheshe, faka phakathi ukuqalisa kwamanje, okuqondiwe kwesikhathi sokusebenza, ukuphindaphinda, nokunwetshwa okuzayo.

Ingabe i-UPS eku-inthanethi ingcono kune-UPS elindile?

Okokusebenza okubalulekile, yebo. I-UPS eku-inthanethi ihlinzeka ngomphumela oqhubekayo wokuguqulwa okukabili kanye nesikhathi sokudlulisa esinguziro. Ngomthwalo oyisisekelo wasekhaya noma wasehhovisi, i-UPS yokulinda ingase yanele.

Ingabe i-UPS enkulu ihlale inikeza isikhathi eside sokusebenza?

Cha. Isikhathi sokusebenza sincike kakhulu emandleni ebhethri namawathi okulayisha. I-UPS enkulu ingasekela amandla engeziwe, kodwa ingase ingasebenzi isikhathi eside ngaphandle uma isistimu yebhethri inkulu.

Ungakanani umthwalo okufanele ngiwubeke ku-UPS?

Ukufakwa okuningi kuklanyelwe ukusebenza ngaphansi komthwalo ogcwele, ngokuvamile cishe ku-60% kuya ku-80%, nemajini eyengeziwe yokuthembeka nokukhula.

Isiphetho

Ukuze ukhethe ukunikezwa kwamandla kwe-UPS okulungile, bala umthwalo, gcina imajini yomthamo, khetha i-topology elungile, setha ukuqondisa okungokoqobo kwesikhathi sokusebenza, bese uqondanisa isistimu nendawo yamandla. Ukukhetha okulungile kunciphisa ubungozi bokugcwala ngokweqile, kuvikela okokusebenza okubalulekile, futhi kuthuthukisa ukuthembeka kwesikhathi eside.
