I-6-220kV i-HV transformer ecwiliswe ngamafutha

I-transformer yamandla

Isiguquli samandla iyisisetshenziswa sikagesi esimile esisetshenziselwa ukuguqula inani elithile le-voltage ye-AC (yamanje) libe elinye noma amanani ahlukene e-voltage (amanje) anefrikhwensi efanayo.

Idivayisi emile enamawindi amabili noma ngaphezulu, ukuze idlulise amandla kagesi, iguqula i-voltage ye-AC kanye neyamanje yesistimu eyodwa ibe amandla kagesi kanye namanje yenye isistimu ngokungenisa kukazibuthe ngefrikhwensi efanayo. Ngokuvamile, amanani ale misinga nama-voltages ahlukile.

I-transformer iyisisetshenziswa sikagesi esimile esisetshenziselwa ukuguqula i-AC voltage kanye neyamanje futhi idlulise amandla kagesi e-AC. Ifinyelela ukudluliswa kwamandla kagesi ngokusekelwe kumgomo wokungeniswa kwe-electromagnetic. Ama-transformers angahlukaniswa abe ama-transformer amandla, ama-test transformers, ama-instrument transformer, kanye neziguquli zenhloso ekhethekile ngokusekelwe ekusetshenzisweni kwazo: ama-transformer kagesi ayimishini edingekayo yokudlulisa nokusabalalisa amandla, kanye nokusabalalisa komsebenzisi wamandla; Imishini yokwenza ukuhlolwa kwe-voltage ukumelana (i-boost) emishinini kagesi kusetshenziswa ama-test transformer; Ama-Instrument transformers asetshenziselwa ukulinganisa kukagesi nokuvikelwa kokudluliselwa kwezinhlelo ezinhlelweni zokusabalalisa (PT, CT); Iziguquli ezinenhloso ekhethekile zihlanganisa ama-smelting furnace transformer, ama-welding transformer, ama-electrolytic rectifier transformer, ama-voltage amancane alawula uguquko, njll.

Isiguquli samandla iyisisetshenziswa sikagesi esimile esisetshenziselwa ukuguqula inani elithile le-voltage ye-AC (yamanje) libe elinye noma amanani amaningana ahlukene e-voltage (yamanje) anefrikhwensi efanayo. Lapho ukushintshana kwamanje kusetshenziswa ekujikeni okuyinhloko, ukuguquguquka kazibuthe kuyakhiqizwa. I-flux kazibuthe eshintshanayo ifakwa ekujikeni kwesibili ngomthelela wokubamba kazibuthe wengqikithi yensimbi, okuholela emandleni e-electromotive ashintshanayo. Ukuphakama kwamandla e-electromotive okwesibili kuhlobene nenani lokuphenduka kumawindi aphambili nawesibili, okungukuthi, i-voltage ilingana ngokuqondile nenani lokujika. Umsebenzi oyinhloko ukudlulisa amandla kagesi, ngakho-ke, umthamo olinganiselwe yipharamitha yawo eyinhloko. Umthamo olinganiselwe inani elivame ukusetshenziswa ukumela amandla, elibonisa usayizi wamandla kagesi adluliswayo, ovezwa nge-kVA noma i-MVA. Uma i-voltage elinganisiwe isetshenziswa ku-transformer, isetshenziselwa ukucacisa okwamanje okulinganiselwe okungadluli umkhawulo wokuphakama kwezinga lokushisa ngaphansi kwezimo ezicacisiwe. I-transformer yamandla eyonga kakhulu i-amorphous alloy iron core distribution transformer, enenzuzo enkulu yokuba nenani eliphansi kakhulu lokulahlekelwa okungalayishiwe. Ukuthi inani lokugcina lokulahlekelwa okungenamthwalo lingaqinisekiswa yini inkinga eyinhloko okufanele icatshangelwe kuyo yonke inqubo yokuklama. Lapho uhlela isakhiwo somkhiqizo, ngaphezu kokucabangela ukuthi i-amorphous alloy iron core ngokwayo ayingaphansi kwamandla angaphandle, kuyadingeka futhi ukukhetha ngokunembile nangokufanele imingcele yesici se-amorphous alloy ngesikhathi sokubala.

ISIHLOKO-UHLOBO-1

Ama-capacitor ahambisanayo kagesi aphezulu afanele ukuxhumana okufanayo kumasistimu kagesi e-AC anefrikhwensi yamandla (50Hz noma 60Hz) ka-1kV nangaphezulu. Asetshenziselwa ukunxephezela amandla asebenzayo e-inductive, ukuthuthukisa isici samandla, ukuthuthukisa ikhwalithi kagesi, ukunciphisa ukulahleka kolayini, nokusebenzisa ngokugcwele ukusebenza kahle kokuphehla ugesi kanye nezisetshenziswa zokuphakela.
