Uhlolojikelele
Lo mkhiqizo ulungele ukulinganisa nokuvikelwa kwangaphakathi kwe-33kV, 35kV, 36kV, AC system metering.
Umkhiqizo ungasetshenziswa ngokuzimela noma ufakwe kumasethi aphelele amakhabhinethi neziteshi ezingaphansi.
I-transformer yamanje ithatha i-high-voltage epoxy resin, i-silicon steel sheet iron core engenisiwe, i-winding isebenzisa i-high-insulation enameled wire yethusi, kanti i-wiring ne-iron core iphathwa ngephepha eliphezulu lokuvikela i-semiconductor.
Isakhiwo Esiyisisekelo
Isakhiwo esiyisisekelo se-voltage transformer sifana kakhulu naleso se-transformer.Futhi inamawindi amabili, enye ibizwa ngokuthi i-primary winding kanti enye ibizwa ngokuthi i-secondary winding.Womabili ama-windings afakwe noma amanxeba azungeze umgogodla wensimbi.Kukhona ukwahlukanisa phakathi kwama-winding amabili naphakathi kwama-windings kanye ne-iron core, ukuze kube nokuhlukaniswa kukagesi phakathi kwama-winding amabili naphakathi kwama-windings kanye ne-iron core.Lapho i-voltage transformer isebenza, i-primary winding N1 ixhunywe kulayini ngokuhambisana, futhi i-N2 yesibili ejikajikayo ixhunywe kuthuluzi noma i-relay ngokuhambisana.Ngakho-ke, lapho ukala i-voltage emgqeni we-high-voltage, nakuba i-voltage eyinhloko iphezulu, eyesibili i-low-voltage, engaqinisekisa ukuphepha kwabaqhubi nezinsimbi.
Izinyathelo zokuzivikela
1. Ngaphambi kokuthi i-voltage transformer iqale ukusebenza, ukuhlolwa nokuhlolwa kuzokwenziwa ngokuya ngezinto ezishiwo 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.
