Kungani Amasistimu Amabili Esikhungo Sedatha Yedatha ku-kVA efanayo Angaba Nezindleko Zephrojekthi Ezihlukile? 

Impendulo eqondile: kungani i-kVA efanayo ingasho izindleko ezifanayo zephrojekthi?

Izingcaphuno ezimbili ezine-UPS kVA efanayo zingaba nezindleko zephrojekthi ezihluke kakhulu ngoba i-kVA ichaza ingxenye kuphela yohlelo oludingekayo. A evumelekile isikhungo sedatha izindleko zokunikezwa kwamandla ezingaphazamiseki ukuqhathanisa kufanele kusebenzise isisekelo esifanayo somthwalo obalulekile, isici samandla, ukwakhiwa kabusha kwezakhiwo, isikhathi sokusebenza kwebhethri nobuchwepheshe, ukuhlelwa kwe-bypass yokulungisa, ukusatshalaliswa okokufaka/okukhiphayo, izixhumanisi zokuqapha, ukuhlola, ukugunyazwa kanye nomngcele wesevisi. Ikhotheshini eyodwa ingafaka ikhabhinethi ye-UPS kuphela, kanti enye ihlanganisa amabhethri, okokusebenza kwe-bypass, ukusatshalaliswa, amakhadi okuxhumana, ukuhlolwa kwesayithi kanye nokwesekwa kokunikezwayo. Abathengi kufanele benze ngokwejwayelekile konke ukufakwa, ukukhishwa kanye nokuqagela ngaphambi kokuqhathanisa inani lentengo noma ukukhetha umphakeli.

Kungani i-kVA iyodwa iyisisekelo senani esingaphelele?

I-kVA elinganiselwe ayiwuvezi umthwalo wangempela obalulekile ku-kW, isici samandla esidingekayo, imajini yokukhula ehleliwe noma ukuthi kubalwa kanjani ukungasasebenzi. Ikhotheshini esuselwe ku-kVA yegama elifanayo ingamela umthamo ohlukile osebenzisekayo noma uhlelo lokunwetshwa. Ishidi lokuqala lokuqhathanisa kufanele lisho umthwalo wamanje obalulekile, umthwalo wokuklama, isici samandla okulayisha, ukuqagela kokukhula kwesikhathi esizayo kanye nokungadingeki okudingekayo.

Abathengi bangabuyekeza okutholakalayo Ububanzi bokunikezwa kwamandla obungaphazamiseki be-UPS, kodwa ukukhethwa komkhiqizo kufanele kuqale kuphela ngemva kokuba isisekelo sephrojekthi evamile sesilungisiwe. Uma kungenjalo, intengo yeyunithi ephansi ingase ibonise nje ububanzi obuncane.

Ingabe isikhathi sokusebenza kanye nobubanzi bebhethri bushintsha kanjani ikhotheshini?

Ububanzi bebhethri bungaba umngcele omkhulu wezindleko zephrojekthi. Umthengi kufanele achaze umthwalo osekelwayo, isikhathi sokusebenza esiqondiwe, ubuchwepheshe bebhethri, ugesi we-DC noma ukuhlelwa kwentambo, ikhabethe noma indawo yokubeka, ukuxhuma, ukuvikelwa, ukuqapha kanye nokuqagela kwemvelo. Isitatimende sesikhathi sokusebenza esingenawo umthwalo obaluliwe asinakuqhathaniswa.

Umphakeli oyedwa angase acaphune i-UPS engenawo amabhethri; enye ingase ihlanganise amabhethri kodwa ingabandakanyi ama-rack, ama-breaker, izintambo noma ukufaka. I isigaba somkhiqizo webhethri isiza ukuhlonza umngcele wemishini ehlukene, kodwa i-RFQ kufanele ixhume leyo scope yebhethri ku-UPS ekhethiwe kanye nezimo zephrojekthi. Ungaguquleli umthamo webhethri ojwayelekile uwenze isikhathi sokusebenza esiqinisekisiwe ngaphandle kokubala okuqondile kwephrojekthi nokuqinisekisa.

Yiziphi izindleko ezishintshayo ngokuphindaphindeka kanye ne-modularity?

I-redundancy inganikezwa kumojula, i-UPS-system noma ileveli yendlela yamandla. Abathengi kufanele basho i-architecture edingekayo futhi bacele abahlinzeki ukuthi babonise ukuthi inani elicashuniwe namandla akwanelisa kanjani. Iphutha elivamile liwukubala imojuli eyengeziwe esidingweni sobuchwepheshe bese uyengeza futhi ngesikhathi sokuqhathanisa ezentengiselwano, noma ucabange ukuthi ifreyimu ye-modular ihlanganisa ngokuzenzakalelayo wonke amamojula wamandla adingekayo kumthwalo wokuklama.

Umkhiqizo ofana ne I-YT-UM Series modular UPS 25–250 kVA ingahlolwa lapho umthamo we-modular ufanelekile. Umthengi usadinga ukuqinisekisa uhlaka, ubuningi bemojuli efakiwe, isibonelelo semojula engasadingeki, izindawo zokunweba zesikhathi esizayo kanye nezinsiza ezifakiwe zokucushwa okucashuniwe.

Yiziphi izinto zokudlula nokusabalalisa ezingahlala ngaphandle kwentengo ye-UPS?

Intengo ye-UPS ingase ingafaki i-bypass yokulungisa yangaphandle, i-switchgear yokufaka nokuphumayo, amaphaneli okusabalalisa, ama-breaker, ikhebula, umzila webhasi, amadivaysi okuzihlukanisa noma umsebenzi wokufaka. Lezi zinto zithinta kokubili izindleko ezinkulu kanye nokugcinwa. Uma umngcele wokudlula ungacacile, umthengi angakhetha ikhotheshini enezindleko eziphansi futhi kamuva athole ukuthi ukugcinwa okuphephile kudinga okokusebenza okwengeziwe kanye nokuhlelwa kokuvala shaqa.

Cela umdwebo womugqa owodwa noma umdwebo wescope omaka impahla enikezwe abahlinzeki kanye nempahla yomthengi. Hlola izilinganiso, ukuxhumana, ubukhulu bomzimba, ukufinyelela nokuxhumana namasistimu akhuphuka nomfula ngaphambi kokuphatha izingcaphuno njengokulinganayo.

Ukuqapha, i-FAT, i-SAT kanye nokuthunywa kuthinta kanjani ububanzi bephrojekthi?

Ukuqapha kungasukela kunkomba yesimo sendawo kuye ekuxhumaneni kwenethiwekhi nokuhlanganiswa kusakhiwo noma inkundla yokuphatha isikhungo sedatha. Abathengi kufanele basho iphrothokholi edingekayo, ihadiwe yokuxhumana, izindawo zokuhlaba umkhosi, imisebenzi ekude kanye nesibopho sokuhlanganisa. "Ukuqapha kufakiwe" akucacile kakhulu ukuthi kungaqhathaniswa nezohwebo.

Ukuhlolwa kokwamukelwa kwefekthri, ukuhlolwa kokwamukelwa kwesayithi kanye nokuthunywa nakho kunemingcele ehlukene. Chaza inqubo yokuhlola, ukuhlelwa komthwalo, imfuneko yofakazi, uhambo, okokusebenza kokuhlola, imibhalo, ukuqeqeshwa kanye nesibopho sokuhlola kabusha. Ukuhlolwa kwasefekthri akuthathi indawo yokuqinisekiswa kwezintambo zesayithi, ukusebenza kwe-bypass, ama-alamu, amabhethri nokuhlanganiswa ngemva kokufakwa.

Yiziphi izinto zomjikelezo wempilo ezingokuqhathaniswa kwezindleko eziphelele ze-UPS?

Ungafaki amandla angasekelwe, amanani ashintshile noma wesevisi. Kunalokho, cela okokufaka okudingekayo kwemodeli yomjikelezo wokuphila eqondene nephrojekthi futhi ukhombe ukuthi iyiphi inhlangano ephethe umsebenzi ngamunye.

Abathengi kufanele bazijwayeze kanjani izingcaphuno ezimbili ze-UPS?

1. Lungisa umthwalo obalulekile ovamile we-kW/kVA, isici samandla nesisekelo sokukhula.
2. Yisho i-architecture edingekayo engasasebenzi kanye namandla asebenzisekayo.
3. Chaza isikhathi sokusebenza ngomthwalo oshiwo kanye nomngcele webhethri ogcwele.
4. Maka konke ukudlula, ukusatshalaliswa, ikhebula nokufakwa kokufaka.
5. Faka kuhlu izinqubo zokuqapha ezidingekayo, ihadiwe nemisebenzi yokuhlanganisa.
6. Chaza i-FAT, i-SAT, ukuthunywa, ukuqeqeshwa kanye nemibhalo.
7. Rekhoda okungafakwanga, okucatshangwayo kanye nezinto zokusebenza ezinikezwe umthengi.
8. Qhathanisa izibopho ze-lifecycle ngokuhlukana nentengo yokuqala yokuhlinzeka.

Le nqubo idalula izindleko ezifihliwe njengokuklama kabusha, izixhumanisi ezingekho, ukuhlola okwengeziwe, ukusebenza kwesizinda okungahleliwe kanye nokubambezeleka kokusebenza.

Imibuzo evame ukubuzwa

Kungani izingcaphuno ezifanayo ze-kVA UPS zingahluka kakhulu?

Angase afake amabhethri ahlukene, ukuphindiselwa kabusha, ukudlula, ukusatshalaliswa, ukuqapha, ukuhlola, ukugunyazwa kanye nemingcele yesevisi.

Ingabe i-UPS kVA yanele ukuqhathanisa umthamo osebenzisekayo?

Cha. Qhathanisa umthwalo obalulekile ku-kW ne-kVA, isici samandla, amamojula afakiwe, ukungasasebenzi kanye nezidingo zokukhula.

Ingabe amabhethri kufanele aqhathaniswe ngokwehlukana?

Yebo, kodwa zixhumanise nomthwalo ofanayo wesikhathi sokusebenza, ubuchwepheshe, ukumisa, ukuvikelwa, ukufakwa kanye nomngcele wokuhlola.

Ingabe ikhotheshini ye-UPS eyimojula ifaka phakathi ukuphinda umsebenzi ngokuzenzakalelayo?

Akunjalo. Qinisekisa usayizi wozimele, amamojula wamandla afakiwe, amamojula angasasebenzi kanye nezikhundla zokunwetshwa zesikhathi esizayo.

Ingabe i-bypass yokulungisa ivamise ukufakwa enanini le-UPS?

Kuya ngengcaphuno. Buza ukuthi ingabe impahla yokudlula yangaphakathi neyangaphandle, i-switchgear kanye nokufakwa kufakiwe.

Iluphi ulwazi lokuqapha oluku-RFQ?

Yisho iphrothokholi edingekayo, ihadiwe, amaphoyinti e-alamu, imisebenzi ekude, ukusebenzelana kweplathifomu kanye nesibopho sokuhlanganisa.

Ingabe ukuhlolwa kwefekthri nokuhlolwa kwesayithi kufanele kufakwe amanani ngokuhlukana?

Kufanele okungenani zichazwe ngokwehlukana ngoba ziqinisekisa izimo ezihlukene futhi zingadinga izinsiza ezahlukene.

Cela ikhotheshini yephrojekthi ye-UPS evamile

Nikeza umthwalo obalulekile ku-kW/kVA, isici samandla, ukwakhiwa kabusha kwezakhiwo, okuqondiwe kwesikhathi sokusebenza, umngcele webhethri, ububanzi bokudlula nokusabalalisa, inqubo yokuqapha, izidingo ze-FAT/SAT, indawo yokugunyaza nokulindelwe kwesevisi. I-Fuhong Xunfei ingasebenzisa lokhu okokufaka ukuze ibuyekeze ukucushwa kwe-UPS okufanele futhi icacise umngcele wengcaphuno. Thumela imininingwane yephrojekthi ngokusebenzisa i- Ikhasi lombuzo wephrojekthi ye-UPS.
