2. Izinga lokungcoliswa: Ⅳ izinga;
3. Ukuthobelana ne-GBl207-2006 “I-Voltage Transformer” ejwayelekile.
Isimiso
Lapho i-voltage transformer isebenza ngokujwayelekile, i-voltage yezigaba ezintathu zohlelo lwamandla ilingana, futhi isamba samandla e-electromotive ezigaba ezintathu kukhoyili yesithathu inguziro.Uma ukubekwa phansi kwesigaba esisodwa kwenzeka, indawo engathathi hlangothi izosuswa, futhi i-voltage elandelanayo eyiziro izovela phakathi kwamatheminali kanxantathu ovulekile ukwenza i-relay isebenze, ngaleyo ndlela ivikele isistimu yamandla.Lapho i-voltage ye-zero-sequence ivela kukhoyili, i-zero-sequence magnetic flux izovela kumongo wensimbi ohambisanayo.Kuze kube manje, lesi siguquli se-voltage esinezigaba ezintathu sithatha umgogodla wejoka oseceleni (lapho i-10KV nangaphansi) noma ama-voltage amathathu esigaba esisodwa.Kulolu hlobo lwe-transformer, ukunemba kwekhoyili yesithathu akuphakeme, kodwa kudinga izici ezithile ze-overexcitation (okungukuthi, lapho i-voltage eyinhloko ikhula, ukuminyana kazibuthe emgodleni wensimbi nakho kukhula ngokuphindaphindiwe okuhambisanayo ngaphandle kokulimala).
Kungani udinga ukushintsha i-voltage kulayini?Lokhu kungenxa yokuthi ngokwezimo ezihlukene zokuphehlwa kukagesi, ukudluliswa nokusetshenziswa kukagesi, ama-voltage emigqeni ahlukile ngobukhulu, futhi umehluko uhluke kakhulu.Ezinye zingama-voltage aphansi angu-220V kanye no-380V, kanti amanye angamashumi ezinkulungwane zama-volt noma amakhulu ezinkulungwane zama-volts.Ukuze ulinganise ngokuqondile lawa ma-voltage aphansi kanye naphezulu-voltage, kuyadingeka ukwenza ama-voltage aphansi kanye naphezulu-voltage ahambisanayo nezinye izinsimbi kanye nama-relay ngokuya ngobukhulu be-voltage yolayini.Lokhu ngeke nje kulethe ubunzima obukhulu ekwakhiweni kwethuluzi, kodwa okubaluleke nakakhulu, akunakwenzeka futhi kunqatshelwe ngokuphelele ukwenza ngokuqondile ithuluzi le-high-voltage futhi ulinganise i-voltage ngqo kulayini we-voltage ephezulu.
Izinyathelo zokuzivikela
1. Ngaphambi kokuthi i-voltage transformer iqale ukusebenza, ukuhlolwa nokuhlolwa kuzokwenziwa ngokuya ngezinto ezibalulwe emithethweni.Isibonelo, ukukala i-polarity, iqembu lokuxhuma, ukuthuthumela okunyakazayo, ukulandelana kwesigaba senuzi, njll.
2. I-wiring ye-voltage transformer kufanele iqinisekise ukunemba kwayo.Amajika-moya ayinhloko kufanele axhunywe ngokuhambisana nesekhethi evivinywayo, futhi ukujikajika kwesibili kufanele kuxhunywe ngokuhambisana nekhoyili ye-voltage yethuluzi lokulinganisa elixhunyiwe, idivayisi yokuvikela i-relay noma idivayisi ezenzakalelayo.Ngesikhathi esifanayo, ukunakwa kufanele kukhokhwe ekunembeni kwe-polarity..
3. Amandla omthwalo oxhunywe ohlangothini lwesibili lwe-voltage transformer kufanele afanele, futhi umthwalo oxhunywe ohlangothini lwesibili lwe-voltage transformer akufanele udlule umthamo wawo olinganiselwe, ngaphandle kwalokho, iphutha le-transformer lizokhula, futhi kunzima ukufeza ukunemba kwesilinganiso.
4. Akukho umjikelezo omfushane ovunyelwe ohlangothini lwesibili lwe-voltage transformer.Njengoba i-impedance yangaphakathi ye-voltage transformer incane kakhulu, uma isifunda sesibili sifushane, kuzovela umsinga omkhulu, ozolimaza imishini yesibili futhi ubeke engozini ukuphepha komuntu siqu.I-voltage transformer ingafakwa i-fuse ohlangothini lwesibili ukuze izivikele ekonakalisweni yi-short circuit ohlangothini lwesibili.Uma kungenzeka, ama-fuse kufanele futhi afakwe ohlangothini oluyinhloko ukuze kuvikelwe igridi yamandla kagesi aphezulu ekubekeni engozini ukuphepha kwesistimu eyinhloko ngenxa yokwehluleka kwamawindi ama-voltage aphezulu e-transformer noma izintambo zokuhola.
5. Ukuze kuqinisekiswe ukuphepha kwabantu lapho bethinta amathuluzi okulinganisa nama-relay, ukuvuthwa kwesibili kwe-voltage transformer kufanele kumiswe endaweni eyodwa.Ngoba ngemva kokubekwa phansi, lapho ukufakwa phakathi kwama-windings ayisisekelo nakwesibili konakalisiwe, kungavimbela i-voltage ephezulu yensimbi kanye ne-relay ekufakeni engozini ukuphepha komuntu siqu.
6. Isifunda esifushane asivunyelwe neze ohlangothini lwesibili lwe-voltage transformer.
