Ukucacisa i-Nameplate: Isikhokelo esipheleleyo seeNkcukacha zeTransformer

Intshayelelo

I-transformer nganye inepleyiti yesinyithi esebenza njengekhadi layo lokwazisa—ipleyiti yegama. Kubasebenzi abangochwephesha bokuthenga, iinjineli, kunye nabaphathi beeasethi, ukuqonda olu lwazi kubalulekile. Ipleyiti yegama iqulethe izibalo ezibalulekileyo ezichaza indlela i-transformer enokuqhutywa ngayo, eqhagamshelwe ngayo, kwaye igcinwe ngayo ubomi bayo bonke.

Esi sikhokelo sichaza iiparameter eziphambili ezifumaneka kwiiplate zamagama zetransformer, sichaza ukuba ithetha ukuthini nganye kunye nesizathu sokuba ibalulekile kwiinkcukacha kunye nokuthengwa kwayo.

Inxalenye Yokuqala: Ukuchongwa koGuquguquko kunye nolwazi oluSisiseko

Phezulu kwepleyiti nganye yegama, uza kufumana igama lomenzi kunye nenombolo yochungechunge eyahlukileyo. Le nombolo yochungechunge ibalulekile ekulandeleni iirekhodi zokwenziwa, iingxelo zovavanyo, kunye namaxwebhu oyilo—ngokuyintloko isatifikethi sokuzalwa setransformer.

Umhla wokwenziwa (inyanga nonyaka) nawo udla ngokunikezelwa, nto leyo evumela uvavanyo lobudala kunye nocwangciso lokugcinwa.

Ipleyiti yegama iya kuchaza ngokucacileyo ukuba iyunithi "yi-transformer" okanye "i-autotransformer," inani lezigaba (isigaba esinye okanye ezintathu), kunye nesantya sokusebenza (ngesiqhelo yi-50 Hz okanye i-60 Hz).

Icandelo lesiBini: Uvavanyo lwaMandla kunye neVolthi

Amandla Alinganisiweyo (i-kVA okanye i-MVA).Oku kubonisa amandla abonakalayo i-transformer enokuyinika rhoqo kwi-voltage elinganisiweyo kunye ne-frequency ngaphandle kokudlula imida yobushushu. Kwi-transformers ezinezigaba ezininzi zokupholisa, amanqaku ahlukeneyo anokuboniswa kwimo nganye.

Uvavanyo lweVoltage.Ulwazi lwe-voltage luvela kwifomathi ethile. Umzekelo, "230000GR.Y / 132800-69000GR.Y / 39840-12470" lubonisa:

• Ukujika kwe-voltage ephezulu: 230,000 V umgca ukuya kumgca, i-Y esekwe phantsi, 132,800 V isigaba-ukuya-kwe-neutral
• Ukujika kwe-voltage ephantsi: 69,000 V umgca ukuya kumgca, i-Y esekwe phantsi, 39,840 V isigaba-ukuya-kwe-neutral
• Ukujika kwenqanaba eliphezulu: Idibene ne-12,470 V delta

Xa kuvela i-slash, yahlula i-voltage yomgca ukuya kumgca kwi-voltage yesigaba ukuya kwe-neutral. I-GR.Y okanye i-Grd.Y ibonisa ukuba i-neutral yenzelwe ukuba ibekwe phantsi-1.

Ulwazi lokucofa.Kwi-transformers ezinee-tap changer, itafile yomlinganiselo we-voltage ibonisa i-voltage kwindawo nganye ye-tap, ivumela abaqhubi ukuba bakhethe useto olufanelekileyo kwiimeko zenkqubo.

Icandelo Lesithathu: Idatha Yokungathinteli kunye Nokulahleka

Ipesenti yokunganyamezelani (%Z).Le parameter ibalulekileyo, echazwa njengepesenti, ibonisa ukwehla kwevolthi xa umthwalo ugcwele. Ichaphazela imisinga yesekethe emfutshane kunye nolawulo lwevolthi. Amaxabiso aqhelekileyo aqala kwi-4% ukuya kwi-15% kuxhomekeke kubukhulu betransformer. Ipesenti ye-impedance ichazwe phakathi kwesibini ngasinye se-windings, kunye nesiseko se-kVA esichaziweyo.

Ukulahleka Okungekho Mthwalo (Ukulahleka Kwentsimbi).Ezi lahleko zenzeka rhoqo nanini na xa i-transformer inikwa amandla, nokuba umthwalo ungakanani na. Zibangelwa kukutsala umbindi kwaye zihambelana kakhulu nomgangatho wezinto ezingundoqo.

Ukulahlekelwa Ngumthwalo (Ukulahlekelwa Yithusi).Ezi lahleko ziyahluka ngokwesikwere somthwalo wangoku kwaye zenzeka kwiingcingo ngenxa yokumelana. Ukulahleka komthwalo okuphantsi kuthetha ukusebenza kakuhle okuphezulu phantsi kweemeko zomthwalo.

Icandelo Lesine: Ulwazi Lokupholisa, Ubushushu, kunye Noqhagamshelo

Iklasi yokuphola.Iitransformer zisebenzisa iikhowudi ezimiselweyo ukubonisa iindlela zokupholisa. Kwiiyunithi ezintywilisiweyo kwioyile, amagama anjenge-ONAN (iOyile yendalo yoMoya weNdalo) okanye i-ONAF (iOyile yendalo yoMoya oQokelelweyo) achaza iindlela zokupholisa zangaphakathi nezangaphandle kunye neendlela zokujikeleza. Isiguquli sohlobo olomileyos, iikhowudi ezifana ne-AN (Air Natural) okanye i-AF (Air Forced) ziyasetyenziswa.

Ukunyuka kobushushu.Oku kuchaza ukunyuka kobushushu okuphezulu ngaphezu kwemozulu apho i-transformer inokumelana rhoqo, ngesiqhelo yi-55°C okanye i-65°C kwiiyunithi ezintywilisiweyo kwioyile. Udidi lwe-insulation (A, B, F, H) lubonisa ubushushu obuphezulu obuvumelekileyo bokusebenza.

Umzobo weVektha kunye noQhagamshelo lweQela.Kwi-polyphase transformers, umzobo wevektha ubonisa ubudlelwane besigaba phakathi kwe-primary windings kunye ne-secondary windings. Iimpawu eziqhelekileyo ezifana ne-Dyn11 zibonisa i-delta primary, i-wye secondary ene-neutral, kunye ne-30-degree phase shift. Umzobo weskimu ubonisa zonke ii-internal connections kunye ne-terminal markings.

Icandelo lesihlanu: Ulwazi loMzimba noKhuseleko

Ubunzima kunye nomthamo weoyile.Iipleyiti zamagama zihlala zidwelisa ubunzima be-core kunye nee-coils, itanki kunye nezinto ezifakelwayo, ioyile yokukhusela, ubunzima obupheleleyo, kunye neyona nto inzima yokuphakamisa. Umthamo weoyile kunye nohlobo lolwelo lokukhusela nazo zichaziwe.

Amanqanaba okukhusela.Inqanaba lokuShukuma kweMpumlo yoMbane eliSisiseko (i-BIL) libonisa amandla e-transformer okumelana nee-voltages zokushushuba, ezichazwe kwi-winding nganye.

Inqanaba lesandi.Ezinye iipleyiti zamagama ziquka ukulinganiswa kwamanqanaba esandi kwiidesibel, ezilinganiswa kumgama oqhelekileyo. Oku kubaluleke kakhulu kwiindawo ezinovakalelo lwengxolo ezifana neendawo zokuhlala okanye izibhedlele.

Isiphelo

Ipleyiti yegama letransformer ingaphezulu kakhulu kunelebheli elula—luxwebhu olupheleleyo lobuchwephesha oluchaza amandla kunye nemida yempahla. Kwiingcali zokuthenga, ukuqonda indlela yokufunda nokutolika olu lwazi kuqinisekisa iinkcukacha ezichanekileyo, kuthintela iimpazamo zokusebenza, kwaye kwenza kube lula ukwenza izigqibo ezinolwazi malunga nokukhetha kunye nokusetyenziswa kwetransformer.
