I-220kV Capacitive Voltage Transformer

Izici Zesakhiwo

◆Umkhiqizo uqukethe izingxenye ezimbili: i-capacitive voltage divider kanye neyunithi ye-electromagnetic.
◆I-Capacitive voltage divider iqukethe i-coupling capacitor eyodwa noma amaningana astakwe ochungechungeni.
◆Itheminali yamandla kagesi aphezulu ingaphezulu kwe-capacitor voltage divider, futhi itheminali kagesi ophakathi nendawo kanye netheminali kagesi ophansi zikhishwa kuyunithi kazibuthe kagesi ngomkhono we-porcelain engxenyeni engezansi ye-chassis ye-voltage ephezulu ye-capacitor.
◆Iyunithi ye-electromagnetic iqukethe i-transformer ephakathi nendawo, i-reactor yesinxephezelo kanye ne-damper.I-capacitor ibekwe phezu kwethangi.Ithangi lamafutha ligcwele uwoyela we-transformer futhi livalwe.Umthamo nokucindezela kwangaphakathi kwamafutha kulungiswa umoya osesigabeni esiphezulu sethangi lamafutha.Ikhoyili eseceleni eyinhloko ye-transformer emaphakathi inekhoyili yokulungisa ukulungisa iphutha le-voltage, futhi ikhoyili yokulungisa ye-reactor yesinxephezelo ilungisa iphutha lesigaba.Okubili Iwindi lesibili elijikajikayo likhishwa ebhokisini letheminali elingaphambi kwethangi likaphethiloli.
◆Lo mkhiqizo ugcwele uwoyela futhi uvalwe uphawu, akukho kwelashwa okukhethekile okufana nesihlungi samafutha noma ukushintsha uwoyela okudingekayo ukuze kugcinwe ukusebenza kukagesi kwasekuqaleni.Khumbula ukuthi ungalimazi ukuvalwa kwe-capacitor voltage divider.Uma iyunithi ye-electromagnetic kufanele ithathe amasampula kawoyela, sicela unake ukuze uqiniseke ukuthi ugcwalisa uwoyela ngesikhathi, nokuthi kufanele uthathe malini.Akudingekile ukuthatha amasampula kawoyela ukuze kwamukelwe nokusebenza okuvamile kwalo mkhiqizo, kungenjalo kuzoletha imiphumela emibi.
◆I-voltage ephezulu ithwalwa ikakhulukazi yi-capacitor voltage divider, futhi amandla e-dielectric nomthelela aphakeme.
◆I-capacitive voltage divider ingaba kabili njenge-coupling capacitor yokuxhumana kwenkampani yenethiwekhi yamandla.
◆Umkhiqizo unamandla uwonke futhi ngeke ubangele i-resonance yefrikhwensi yamandla kanye ne-ferromagnetic resonance yesistimu yamandla.
◆Yamukela ubuchwepheshe obuthuthukisiwe bokumanzisa be-reactor egcwala ngokushesha, engacindezela ngokushesha nangempumelelo i-ferromagnetic resonance futhi iqinisekise ukusebenza kwempendulo yesikhashana.
◆Zonke izingxenye ze-insulating zalo mkhiqizo zenziwe ngezinto ezivikela imvelo.
◆Ibhodi lezintambo zesibili lamukela ukwakheka kwe-epoxy resin, futhi ukusebenza kokuvala kunokwethenjelwa kakhulu.
◆Izingxenye zensimbi ezivuzayo ezingaphandle njengesisekelo somkhiqizo zisebenzisa izinqubo ezimbili zokunqanda ukugqwala kokufuthwa nokufaka ugesi oshisayo, ezinhle futhi ezisebenza kahle ekunqandeni ukugqwala.
◆ Izibophelelo, ama-nameplates, njll. zonke ziyinsimbi engagqwali.
