Ukukhetha Ama-Transformer Ezikhungo Zedatha

Esikhathini sokuguqulwa kwedijithali, izikhungo zedatha sezibe yinhliziyo yamabhizinisi, futhi ama-transformer ayimishini ebalulekile egcina lokhu kushaya kwenhliziyo. Ukukhetha i-transformer efanele akuhlobene nje kuphela nokusebenza kahle kwamandla kanye nezindleko zokusebenza kwesikhungo sedatha kodwa futhi kuthinta ngqo ukuqhubeka kwebhizinisi kanye nokuphepha kwedatha.

Ukukhetha ama-transformer ezikhungo ezinkulu zedatha kudinga ukucatshangelwa kwezimiso eziningi okuhlanganisa umthamo womthwalo, ukusebenza kahle kanye nokusetshenziswa kwamandla, ukuzinza, ukuthembeka, kanye nokuzivumelanisa nezimo. Njengemishini eyinhloko yesistimu yamandla, ukukhethwa kanye nokusethwa kwama-transformer kuthinta ngqo ukusebenza okuzinzile kwesikhungo sedatha sonke.

Lesi sihloko sizochaza izinto ezibalulekile okufanele uzicabangele lapho ukhetha ama-transformer afanele izikhungo zedatha ukuze sikusize wenze izinqumo ezinolwazi.

1. Izidingo Ezikhethekile Zama-Data Center Transformers

Izikhungo zedatha zinezidingo eziphakeme kakhulu zokuhlinzekwa kukagesi. Umthwalo uqukethe ikakhulukazi imishini yolwazi lwe-elekthronikhi efana namaseva, amadivayisi okugcina, kanye nemishini esekelayo efana nezinhlelo zokupholisa umoya kanye nokupholisa. Ukuze kugwenywe ukuphazamiseka okuvela emishinini yokupholisa umoya kanye nokupholisa kumadivayisi kagesi, ama-transformer avame ukusethwa ngokwehlukana ngokwezigaba ezahlukene zomthwalo ngesikhathi sokucushwa kwesistimu.

Ama-transformer esikhungo sedatha azinikele kudingeka abe nezici ezilandelayo:

Izidingo Zokuthembeka Okuphezulu: Isigaba somthwalo (ibanga) ezikhungweni zedatha singaphezu kakhulu kweLevel 1, okudinga ukuthembeka okuphezulu kakhulu kokunikezwa kwamandla.

Izidingo Zokusebenza Kahle Kakhulu: Kufanele kuhlangatshezwane noma kudlule amazinga okusebenza kahle kwamandla eSigaba 1.

Amandla Okuthwala Umthwalo Oqinile: Uyakwazi ukusingatha ukwanda komthwalo ngokuzumayo.

Izidingo Eziphezulu Zokuphepha Komlilo: Qinisekisa ukusebenza okuphephile kwesikhungo sedatha.

2. Izici Zokukhetha Eziyinhloko

2.1 Umthamo Womthwalo kanye Nezinga Lomthwalo

Ukukhetha i-transformer enomthamo owanele womthwalo kubaluleke kakhulu ngoba umthwalo wezikhungo ezinkulu zedatha uvame ukwanda ngokuthuthuka kwebhizinisi.

Izinga lomthwalo elifanele (umthwalo wangempela / umthamo olinganisiwe) we-transformer lingu-70%-85%, okuwububanzi begolide obuqashelwa embonini. Izinga lomthwalo elingaphansi kuka-70% libangela ukuthi i-transformer isebenze ngaphansi komthwalo olula isikhathi eside, kanti ukulahlekelwa okungenamthwalo kubalelwa engxenyeni ephezulu kakhulu. Ngakolunye uhlangothi, izinga lomthwalo elingaphezu kuka-85% lisunduza i-transformer eduze komthwalo ogcwele, okwandisa ukushisa kwekhoyili futhi kwandisa kakhulu ingozi yokwehluleka.

2.2 Ukusebenza Kahle Nokusetshenziswa Kwamandla

Izikhungo zedatha ezinkulu ngokuvamile zidinga ukusebenza isikhathi eside, ngakho-ke ukusebenza kahle kwe-transformer kanye nokusetshenziswa kwamandla kuyizinto ezibalulekile okufanele zicatshangelwe. Ama-transformer asebenza kahle kakhulu anganciphisa ukusetshenziswa kwamandla futhi athuthukise ukusetshenziswa kwamandla, onge izindleko zokusebenza kwezikhungo zedatha.

Uma ukhetha i-transformer, kubalulekile ukuqhathanisa hhayi nje intengo yokuthenga kodwa futhi "nokulahlekelwa umthwalo + ukulahlekelwa umthwalo." Lokhu kulahlekelwa kuyizibulali ezingabonakali zezikweletu zikagesi futhi, ngokuhamba kwesikhathi, kungase kudlule kakhulu umehluko wentengo yokuqala.

2.3 Ukuzinza Nokuthembeka

Ukuzinza kubaluleke kakhulu ngesikhathi sokusebenza kwesikhungo sedatha. Ukukhetha i-transformer eqinile kakhulu kungaqinisekisa ukusebenza okuvamile kwesikhungo sedatha, kugweme ukulahleka kwedatha noma ezinye izinkinga ezibangelwa izinkinga ze-voltage.

Ukuthembeka kungenye yezindinganiso ezibalulekile zokulinganisa ikhwalithi yemishini. I-transformer ethembekile ingagwema ukuphazamiseka kwedatha nokulahlekelwa okubangelwa ukwehluleka kwemishini. Ukusebenza okuqhubekayo kwesikhungo sedatha kubalulekile emabhizinisini, ngakho ukukhetha ama-transformer anokwethenjelwa okuphezulu nokuqina kubaluleke kakhulu.

2.4 Ukuzinza Kwe-Voltage Nokucindezela Okuvumelanayo

Ama-transformer kufanele abe nokuqina kwamandla kagesi aphezulu ukuqinisekisa ukuthi imishini yesikhungo sedatha ingasebenza kahle futhi igweme umonakalo ovela ekushintsheni kwamandla kagesi. Ezikhungweni zedatha, imishini efana namaseva kanye ne-UPS iyazwela kuma-harmonics (ama-harmonics amaningi angabangela ukungasebenzi kahle kwemishini). Kuyadingeka ukukhetha ama-transformer anezinga eliphansi lokuhlanekezela kwe-harmonic (≤3%) kanye nomsebenzi wokucindezela i-harmonic.

2.5 Ukusebenza Kokushabalalisa Ukushisa

Njengoba imishini ezindaweni ezinkulu zedatha ikhiqiza ukushisa okukhulu ngesikhathi sokusebenza, ama-transformer kudingeka abe nokusebenza okuhle kakhulu kokushabalalisa ukushisa ukuze avimbele ukwehluleka okubangelwa ukushisa ngokweqile. Ukushabalalisa ukushisa kwama-transformer ezindawo zedatha kusebenzisa kakhulu indlela ye-AN/AF, okungukuthi, ukupholisa kwemvelo okunezelwa ukupholisa umoya okuphoqelelwe.

2.6 Ukuvikelwa Nokuphepha Kwemvelo

Izikhungo zedatha zanamuhla zigxila kakhulu ekuvikelweni kwemvelo kanye nokusebenza kokuphepha. Izinto zokuvikela irabha ye-silicone ezisebenza kahle kakhulu zinezimpawu zokusha ze-V0 grade—azishisi futhi azikhiqizi intuthu enobuthi—okwenza zifaneleke kakhulu ezidingweni zokuphepha komlilo zezikhungo zedatha. Ngaphezu kwalokho, izingxenye eziyinhloko zezinto zokuvikela irabha ye-silicone yi-dimethylsiloxane kanye nama-filler aqhuba ukushisa, angenabo ubuthi. Azinangozi empilweni yabantu ngesikhathi sezinqubo zokukhiqiza, ukusebenza, kanye nokuvuselela ama-transformer windings, azibandakanyi igesi yokukhipha noma ukukhishwa koketshezi olungcolile, futhi izinto zingaphinde zisetshenziswe ekupheleni komjikelezo wazo wokuphila.
