Isishwankathelo
Le mveliso ifanelekile kwi-33kV yangaphakathi, i-35kV, i-36kV, i-AC system metering kunye nokukhusela.
Imveliso ingasetyenziselwa ngokuzimeleyo okanye ifakwe kwiisethi ezipheleleyo zeekhabhinethi kunye neendawo ezincinci.
I-transformer yangoku ithatha i-high-voltage epoxy resin, i-silicon sheet sheet yentsimbi engundoqo, i-winding ithatha i-high-insulation enameled ucingo lobhedu, kwaye umbindi wentsimbi uphathwa ngephepha lokukhusela le-semiconductor elikumgangatho ophezulu.
Ulwakhiwo olusisiseko
Isakhiwo esisisiseko se-voltage transformer siyafana kakhulu neso siguquli.Kananjalo inamajiko-jiko amabini, enye ibizwa ngokuba yi-primary winding kwaye enye ibizwa ngokuba kukujija okwesibini.Omabini amajiko-jiko axhonywe okanye amanxeba ajikeleze umbindi wentsimbi.Kukho ukugquma phakathi kwamajiko-jiko amabini kunye naphakathi kwamajiko-jiko kunye nombindi wentsimbi, ukuze kubekho ukwahlulwa kombane phakathi kwamajiko-jiko amabini kunye naphakathi kwamajiko-jiko kunye nombindi wentsimbi.Xa i-voltage transformer isebenza, i-primary winding N1 ixhunywe kumgca ngokuhambelanayo, kunye ne-N2 yesibini edibeneyo ixhunyiwe kwisixhobo okanye i-relay ngokufana.Ngoko ke, xa ulinganisa i-voltage kumgca we-high-voltage, nangona i-voltage ephambili iphezulu, i-second-voltage ephantsi, enokuqinisekisa ukhuseleko lwabaqhubi kunye nezixhobo.
Ukulumkela
1. Ngaphambi kokuba i-voltage transformer isetyenziswe, uvavanyo kunye nokuhlolwa kuya kwenziwa ngokwezinto ezichazwe kwimimiselo.Umzekelo, ukulinganisa i-polarity, iqela lokudibanisa, ukugquma ukugquma, ukulandelelana kwesigaba senyukliya, njl.
2. I-wiring ye-voltage transformer kufuneka iqinisekise ukuchaneka kwayo.Umoya ophambili kufuneka udityaniswe ngokuhambelana nesekethe phantsi kovavanyo, kwaye ukuvuthwa kwesibini kufuneka kudityaniswe ngokuhambelana ne-coil ye-voltage yesixhobo sokulinganisa esixhunyiwe, isixhobo sokukhusela i-relay okanye isixhobo esizenzekelayo.Ngelo xesha, ingqalelo kufuneka ihlawulwe ekuchanekeni kwe-polarity..
3. Umthamo womthwalo oqhagamshelwe kwicala lesibini le-voltage ye-voltage kufuneka ulungele, kwaye umthwalo oqhagamshelwe kwicala lesibini le-voltage ye-voltage akufanele udlule umthamo wayo olinganisiweyo, ngaphandle koko, impazamo ye-transformer iya kwanda, kwaye kunzima ukufezekisa ukuchaneka komlinganiselo.
4. Akukho mjikelezo omfutshane uvunyelwe kwicala lesibini le-voltage transformer.Ekubeni i-impedance yangaphakathi ye-voltage transformer incinci kakhulu, ukuba isiphaluka sesibini sifutshane, kuya kuvela umsinga omkhulu, oya kulimaza izixhobo zesibini kunye nokuba yingozi yokhuseleko lomntu.I-voltage transformer inokuxhotyiswa nge-fuse kwicala lesibini ukuzikhusela ekonakalisweni yisiphaluka esifutshane kwicala lesibini.Ukuba kunokwenzeka, i-fuses kufuneka ifakwe kwicala eliphambili ukukhusela igridi yamandla e-high-voltage engozini yokhuseleko lwenkqubo ephambili ngenxa yokungaphumeleli kwe-transformer's high-voltage windings okanye iingcingo ezihamba phambili.
5. Ukuze kuqinisekiswe ukukhuseleka kwabantu xa bechukumisa izixhobo zokulinganisa kunye nee-relays, i-second winding ye-voltage transformer kufuneka ibekwe phantsi kwinqanaba elinye.Ngenxa yokuba emva kokumiswa komhlaba, xa ukugquma phakathi kwe-winding ephambili kunye neyesibini yonakele, kunokuthintela i-voltage ephezulu yesixhobo kunye ne-relay engozini yokhuseleko lomntu.
6. Isiphaluka esifutshane asivumelekanga ngokupheleleyo kwicala lesibini le-voltage transformer.
