Ukuhlela Ipuleti Legama: Umhlahlandlela Ophelele Wezincazelo Ze-Transformer

Isingeniso

I-transformer ngayinye inepuleti lensimbi elisebenza njengekhadi layo lokuzazisa—ipuleti legama. Kwabochwepheshe bokuthenga, onjiniyela, kanye nabaphathi bezimpahla, ukuqonda lolu lwazi kubalulekile. Ipuleti legama liqukethe izibalo ezibalulekile ezichaza ukuthi i-transformer ingasebenza kanjani, ixhunywe futhi igcinwe kanjani kuyo yonke impilo yayo yenkonzo.

Lo mhlahlandlela uchaza amapharamitha ayisihluthulelo atholakala kuma-nameplate e-transformer, uchaza ukuthi ngalinye lisho ukuthini nokuthi kungani libalulekile ekucacisweni nasekuthengweni.

Ingxenye Yokuqala: Ukuhlonza i-Transformer kanye nolwazi oluyisisekelo

Phezulu kwepuleti ngalinye legama, uzothola igama lomenzi kanye nenombolo yochungechunge ehlukile. Le nombolo yochungechunge ibalulekile ekulandeleni amarekhodi okukhiqiza, imibiko yokuhlola, kanye nemibhalo yokuklama—ngokuyisisekelo isitifiketi sokuzalwa se-transformer.

Usuku lokukhiqiza (inyanga nonyaka) luvame ukuhlinzekwa, okuvumela ukuhlolwa kweminyaka kanye nokuhlela ukulungiswa.

Ipuleti legama lizosho ngokusobala ukuthi iyunithi "iyi-transformer" noma "i-autotransformer," inani lezigaba (isigaba esisodwa noma ezintathu), kanye nemvamisa yokusebenza (ngokuvamile i-50 Hz noma i-60 Hz).

Ingxenye Yesibili: Izilinganiso Zamandla Ne-Voltage

Amandla Alinganisiwe (i-kVA noma i-MVA).Lokhu kubonisa amandla abonakalayo i-transformer engawanikeza ngokuqhubekayo ku-voltage elinganisiwe kanye nemvamisa ngaphandle kokudlula imikhawulo yokushisa. Kuma-transformer anezigaba eziningi zokupholisa, izilinganiso ezahlukene zingaboniswa kwimodi ngayinye.

Izilinganiso ze-Voltage.Ulwazi lwe-voltage luvela ngefomethi ethile. Isibonelo, i-"230000GR.Y / 132800-69000GR.Y / 39840-12470" ikhombisa:

• Ukugoqa okunamandla aphezulu: 230,000 V umugqa kuya kumugqa, i-Y egxilile, 132,800 V isigaba-kuya-kwengxenye
• Ukujikeleza kwe-voltage ephansi: 69,000 V umugqa kuya kumugqa, i-Y egxilile, 39,840 V isigaba-kuya-kwe-neutral
• Ukugoba okuphezulu: 12,470 V delta-connected

Uma kuvela i-slash, ihlukanisa i-voltage yomugqa kuya komugqa kusuka ku-voltage yesigaba kuya kwe-neutral. I-GR.Y noma i-Grd.Y ikhombisa ukuthi i-neutral ihloselwe ukumiswa-1.

Ulwazi Lokuthepha.Kuma-transformer anezishintshi zempompi, ithebula lesilinganiso se-voltage libonisa i-voltage endaweni ngayinye yokumpompi, okuvumela opharetha ukuthi bakhethe ukulungiselelwa okufanele kwezimo zesistimu.

Ingxenye Yesithathu: Idatha Yokuvinjelwa Nokulahlekelwa

Iphesenti Lokungavimbeli (%Z).Le pharamitha ebalulekile, evezwa njengephesenti, ikhombisa ukwehla kwe-voltage lapho umthwalo ugcwele. Ithinta ama-current-circuit currents kanye nokulawulwa kwe-voltage. Amanani ajwayelekile asukela ku-4% kuya ku-15% kuye ngobukhulu be-transformer. Iphesenti lokuphazamiseka lichazwa phakathi kwepheya ngalinye lama-windings, kanye nesisekelo se-kVA esishiwo.

Ukulahlekelwa Okungenamthwalo (Ukulahlekelwa Yinsimbi).Lokhu kulahlekelwa kwenzeka njalo noma nini lapho i-transformer inikwa amandla, kungakhathaliseki ukuthi umthwalo ungakanani. Kubangelwa ukukhanga umgogodla futhi kuhlobene eduze nekhwalithi yezinto eziyinhloko.

Ukulahlekelwa Umthwalo (Ukulahlekelwa Yithusi).Lokhu kulahlekelwa kuyahlukahluka ngesikwele somthwalo wamanje futhi kwenzeka kuma-windings ngenxa yokumelana. Ukulahlekelwa umthwalo okuphansi kusho ukusebenza kahle okuphezulu ngaphansi kwezimo ezilayishiwe.

Ingxenye Yesine: Ulwazi Lokupholisa, Izinga Lokushisa, kanye Nokuxhumana

Ikilasi Lokupholisa.Ama-transformer asebenzisa amakhodi ajwayelekile ukukhombisa izindlela zokupholisa. Kumayunithi acwiliswe ku-oyili, izikhundla ezifana ne-ONAN (Oil Natural Air Natural) noma i-ONAF (Oil Natural Air Forced) zichaza izindlela zokupholisa zangaphakathi nezangaphandle kanye nezindlela zokujikeleza kwegazi. I-Transformer Yohlobo Olomiles, kusetshenziswa amakhodi afana ne-AN (Air Natural) noma i-AF (Air Forced).

Ukwenyuka Kwezinga Lokushisa.Lokhu kucacisa ukwenyuka kwezinga lokushisa okuphezulu ngaphezu kwendawo lapho i-transformer ingamelana khona njalo, ngokuvamile okungu-55°C noma 65°C kumayunithi acwiliswe uwoyela. Isigaba sokushisa (A, B, F, H) sibonisa izinga lokushisa lokusebenza eliphakeme kakhulu elivunyelwe.

I-Vector Group kanye nomdwebo woxhumano.Kuma-transformer e-polyphase, umdwebo we-vector ukhombisa ubudlelwano besigaba phakathi kwama-windings ayinhloko nawesibili. Izimpawu ezivamile ezifana ne-Dyn11 zibonisa i-delta primary, i-wye secondary ene-neutral, kanye nokushintsha kwesigaba sama-degree angu-30. Umdwebo we-schematic ukhombisa konke ukuxhumana kwangaphakathi kanye nezimpawu ze-terminal.

Ingxenye Yesihlanu: Ulwazi Lomzimba Nokuphepha

Izisindo kanye nomthamo wamafutha.Ama-nameplate ngokuvamile abhala isisindo se-core kanye nama-coil, ithangi kanye nezinto zokufaka, uwoyela wokuvikela, isisindo esiphelele, kanye nengxenye esindayo kakhulu yezinjongo zokuphakamisa. Umthamo kawoyela kanye nohlobo loketshezi lokuvikela nakho kuyachazwa.

Amazinga Okushisa.Izinga Lokushintshwa Komoya Okhanyayo Eliyisisekelo (BIL) libonisa ikhono le-transformer lokubekezelela ama-voltage okukhuphuka, achazwe ku-winding ngayinye.

Izinga Lomsindo.Amanye ama-nameplate afaka izilinganiso zezinga lomsindo ngama-decibel, alinganiswa ngebanga elijwayelekile. Lokhu kubaluleke kakhulu ekufakweni ezindaweni ezizwela umsindo njengezindawo zokuhlala noma izibhedlela.

Isiphetho

Ipuleti legama le-transformer lingaphezu kakhulu kwelebula elilula—liyidokhumenti yobuchwepheshe ephelele echaza amakhono kanye nemikhawulo yempahla. Kwabochwepheshe bokuthenga, ukuqonda indlela yokufunda nokuhumusha lolu lwazi kuqinisekisa ukucaciswa okulungile, kuvimbela amaphutha okusebenza, futhi kwenza kube nokwenzeka ukwenza izinqumo ezinolwazi mayelana nokukhetha kanye nokusetshenziswa kwe-transformer.
