Isingeniso
I-Transformer iyithuluzi elimile eliguqula amandla kagesi e-AC ukusuka ku-voltage eyodwa ukuya kwenye igcina imvamisa ifana ngomgomo wokungeniswa kukagesi.
Okokufaka ku-transformer nokuphumayo okuvela ku-transformer kokubili amanani ashintshanayo (AC).Amandla kagesi akhiqizwa futhi adluliselwe ngama-voltage aphezulu kakhulu. I-voltage izobe isiyehliswa ibe inani eliphansi ukuze isetshenziswe ekhaya nasezimbonini. Lapho i-transformer ishintsha izinga le-voltage, ishintsha izinga lamanje futhi.
Isimiso Sokusebenza
I-winding eyinhloko ixhunywe ku-single - phase ac supply, i-ac current iqala ukugeleza kuyo. I-ac primary current ikhiqiza i-alternating flux (Ф) kumongo. Iningi lalokhu kuguquguquka okuguquguqukayo kuxhunyaniswa nokujika kwesibili kumongo.
Ukuguquguquka okuhlukahlukene kuzongenisa i-voltage kumajika esibili ngokuya ngemithetho ye-faraday yokungeniswa kukazibuthe. Izinga le-voltage liyashintsha kodwa imvamisa okungukuthi isikhathi asishintshi. Akukho ukuthintana kukagesi phakathi kwama-winging amabili, amandla kagesi adluliswa esuka kwesisekelo aye kweyesibili.
I-transformer elula iqukethe ama-conductor amabili kagesi abizwa ngokuthi i-primary winding kanye ne-secondary winding. Amandla ahlanganiswa phakathi kwama-windings ngesikhathi ukushintshashintsha kukakazibuthe okudlula(izixhumanisi) kokubili ama-winding ayisisekelo nakwesibili.
Izesekeli Ezibalulekile Ze-Power Transformer
1.Buchholz edluliselwe
Le relay yakhelwe ukuthola iphutha langaphakathi le-transformer esigabeni sokuqala ukugwema ukuwohloka okukhulu. I-float ephezulu iyazungeza futhi ishintshe othintana nabo bavale futhi ngaleyo ndlela inikeze i-alamu.
2.Oil Surge Relay
Lokhu kudluliselwa kungabhekwa ngokucindezela inkinobho yokuhlola enikezwe ngenhla. Lapha kunikezwa othintana naye oyedwa kuphela onikeza isignali yohambo ekusebenzeni kwe-float. Ngokufinyeza ukuxhumana ngaphandle ngesixhumanisi, isifunda sohambo singabuye sihlolwe.
3.I-Explosion Vent
Iqukethe ipayipi eligobile eline-Bakelite diaphragm kuzo zombili iziphetho. I-wire mesh evikelayo ifakwe ekuvuleni kwe-transformer ukuvimbela izingcezu ze-diaphragm ephukile ukuthi zingangeni ethangini.
I-4.I-Valve Yokukhulula Ukucindezeleka
Lapho umfutho ethangini ukhuphuka ngaphezu komkhawulo ophephile onqunywe kusengaphambili, le valve iyasebenza futhi yenze le misebenzi elandelayo: -
Ivumela ingcindezi ukuthi yehle ngokuvula imbobo ngokushesha.
Inikeza inkomba ebonakalayo yokusebenza kwevalvu ngokuphakamisa ifulegi.
Isebenzisa i-micro switch, enikeza umyalo wohambo ku-breaker.
5.Oil Temperature Indicator
Kuyi-thermometer yohlobo lokudayela, isebenza kumgomo wokucindezela komhwamuko. Yaziwa nangokuthi yi-magnetic oil gauge (MOG). Inozibuthe. Udonga lwensimbi lwethangi le-conservator luhlukanisa odonsa ngaphandle kwembobo.Inkundla kaMagnetic iyaphuma futhi isetshenziselwa inkomba.
6.Winding Temperature Inkomba
Iphinde ifane ne-OTI kodwa inezinguquko ezithile. Iqukethe i-probe efakwe ama-capillary angu-2. Ama-capillaries axhunywe ngezimbongolo ezimbili ezihlukene (ezisebenzayo/ezinxephezela). Lezi zifutho zixhunywe nesikhombisi sezinga lokushisa.
7.Umlondolozi
Njengoba ukunwetshwa nokufinyela kwenzeka ethangini eliyinhloko le-transformer, ngenxa yalokho kwenzeka okufanayo ku-conservator njengoba lixhunywe ethangini elikhulu ngepayipi.
8.Umfowethu
Lesi isihlungi somoya esikhethekile esihlanganisa into eqeda amanzi emzimbeni, ebizwa ngokuthi, i-Silica Gel. Isetshenziselwa ukuvimbela ukungena komswakama nomoya ongcolile ku-conservator.
9.Ama-radiator
Ama-Transformer Amancane ahlinzekwa ngamashubhu okupholisa ashiselwe noma ama-radiator ensimbi acindezelwe. Kodwa ama-transformer amakhulu anikezwa ama-radiator atholakalayo kanye nama-valve. Ukuze uthole ukupholisa okwengeziwe, abalandeli bokukhipha amandla banikezwa kuma-radiator.
10.Thinta Guqula
Njengoba umthwalo ku-transformer ukhula, i-voltage yesibili yokugcina iyancipha.Kunezinhlobo ezimbili zokushintsha kompompi.
A.Off Layisha Tap Changer
Kulolu hlobo, ngaphambi kokuhambisa isikhethi, i-transformer yenziwa OFF kuzo zombili iziphetho. Izishintshi zompompi ezinjalo zinokuthintana kwethusi okungashintshi, lapho ompompi benqanyulwa khona. Othintana nabo abahambayo benziwa ngethusi ngesimo se-roller noma ingxenye.
B.On Load Tap Changer
Ngamafuphi sikubiza ngokuthi i-OLTC. Kulokhu, ompompi bangashintshwa ngesandla ngokusebenza ngomshini noma ngogesi ngaphandle kokwenza i-transformer. Ngokusebenza kokusebenza komshini, izingidi zihlinzekwa ngokungasebenzi kwe-OLTC ngaphansi kwendawo yokuthepha ephansi kakhulu nangaphezulu kwendawo yokuthepha.
11.RTCC (I-Remote tap control cubicle)
Isetshenziselwa ukushintsha kampompi ngesandla noma ngokuzenzakalelayo nge-Automatic Voltage Relay (AVR) esethwe +/- 5% ka-110 Volt (Inkomba ethathwe ku-voltage ye-PT yohlangothi lwesibili).
