Nakuba i-PDU (Iyunithi Yokusabalalisa Amandla) kanye nomugqa wamandla ojwayelekile kubukeka kufana kakhulu, kusenomehluko ezicini ezilandelayo.
1. Imisebenzi ihlukile.
Izintambo zikagesi ezijwayelekile zinemisebenzi yokulayisha ngokweqile kwamandla kanye nokulawula okuphelele, kanti nezindawo zokuphuma nazo ziyisicefe kakhulu; Kodwa ama-PDU awanayo nje inhlobonhlobo yemisebenzi (umsebenzi wokuvikela umbani, ukushintsha kokulawula okuphelele, ukuvikela ukulayisha ngokweqile, isibonisi samanje nesikagesi, umsebenzi wokuqapha okukude, ukutholwa kwentuthu/ izinga lokushisa/umswakama ku-inthanethi, njll.), kodwa futhi nesistimu yemojula yokuphumayo ingakwazi kufanele ifaniswe ngokunengqondo futhi ikhethwe ngokwesimo esithile. (Kukhona indinganiso yamaShayina, indinganiso yaseMelika, i-IEC yamazwe ngamazwe, indinganiso yaseJalimane, njll.)
2. Izinto ezisetshenziswayo zihlukile
Imichilo yamandla evamile ngokuvamile iyipulasitiki, kuyilapho ama-PDU eyi-all-metal. Uma umthwalo umkhulu kakhulu, i-PDU ingaba nomlilo, kuyilapho isokhethi evamile ingenawo. Njengoba i-PDU inezindlu zensimbi, inomsebenzi we-anti-static, ovikela imishini ye-elekthronikhi ebucayi ezingozini zikagesi we-static, ngaleyo ndlela ivikele ukusebenza okuzinzile kwemishini.
3. Izindawo zokufaka izicelo zihlukile
Amasokhethi avamile ngokuvamile asetshenziswa ezindlini noma emahhovisi ukuze kuhlinzekwe amandla ezintweni zikagesi ezifana namakhompyutha, kuyilapho amasokhethi e-PDU evamise ukusetshenziswa ezikhungweni zedatha, amasistimu enethiwekhi nezimo zezimboni, futhi afakwa kuma-rack wemishini, anikeze amandla okushintsha, amarutha, nokunye. amadivaysi.
4. Amandla omthwalo ahlukene
Umthwalo wekhebula lomugqa wamandla ojwayelekile awunamandla uma kuqhathaniswa, isilinganiso esiningi singu-10A ngentambo engu-1.5 mm2. Abakhiqizi abambalwa bazolebula igama elithi 16A 4000W. Ngokwezindinganiso kazwelonke zezintambo zentambo, kungakhathaliseki ukuthi yikuphi ukucushwa, amandla okulayisha alinganiselwe anzima kakhulu ukufeza u-4000W ngempela. Kuyabonakala ukuthi kunzima ukuhlangabezana nezidingo zegumbi lekhompyutha elikhula ngokushesha. I-PDU ngokungangabazeki ukuxazulula le nkinga ngezinga elikhulu, ngoba noma yiziphi izingxenye zayo zenziwa ngokwezifiso ngokusekelwe ezimweni ezihlukene, ezingahlangabezana ngokugcwele nokuphepha kwemvelo yegumbi lamandla. Njengamanje, amapulaki ezimboni asetshenziswa kakhulu ku-PDU, okwamanje akwazi ukuhlangabezana nezidingo ze-16A, 32A, 65A, 125A njalonjalo, futhi amandla awo okulayisha alinganiselwe angafinyelela ngaphezu kwe-4000W ukuze ahlangabezane nezidingo zamandla zegumbi lekhompyutha. Ngaphezu kwalokho lapho umthwalo wamandla we-PDU mkhulu kakhulu, ungacisha ngokuzenzakalelayo, ngezinga elithile lomsebenzi wokumelana nomlilo. Ngakho-ke, ukusetshenziswa komugqa wamandla ojwayelekile kukhabhinethi engu-19” akulungile kakhulu.
5. Ubude bempilo buhlukene
Imichilo yamandla evamile ingasetshenziswa iminyaka engu-2-3., Cishe izikhathi ezingu-4500-5000 zokuxhunywa, kuyilapho isokhethi le-PDU lenziwe ngensimbi esebenza kakhulu-insimbi (i-phosphorus) yethusi futhi inokumelana nokuguga okuhle kanye nokuhamba kukagesi. Ngamandla omthwalo ogcwele wehora, izinga lokushisa layo likhuphuka ngama-degree angu-20 kuphela, ngaphansi kwezinga likazwelonke lama-degree angu-45, okuvimbela ngokuphumelelayo izici zokushisa. Ine-hot-plug izikhathi ezingaphezu kuka-10000, futhi impilo ifinyelela eminyakeni eyi-10.
INGABE i-PDU ingasetshenziswa ekhaya?
YEBO! Ngokusekelwe kulo mehluko oshiwo ngenhla phakathi kwe-PDU nomugqa wamandla ojwayelekile, kungakhathaliseki ukuthi ngokomsebenzi, ukuphepha noma okunye ukusebenza, i-PDU iyisinqumo esingcono kakhulu sikagesi wasekhaya, ngoba iphephile futhi iyonga.
Isifinyezo
I-PDU inemisebenzi izintambo zamandla ezijwayelekile ezingenayo. Ngikholelwa ukuthi esikhathini esizayo, i-PDU ngeke isetshenziswe kuphela ohlelweni lwenethiwekhi, kodwa futhi ithatha indawo yomugqa wamandla ojwayelekile ezinkulungwaneni zemizi.
