Transformer owodwa esigabeni. Inhloso, isakhiwo main izici

Kukhona ihlaya elidala sikhungo. On umbuzo uthisha "indlela transformer owodwa esigabeni" kuyachwaza umfundi ephendula: "Oo-oo-oo". Umsindo lokhu empeleni kwenzeka, kungenxa yokuthi uma uhambisa kuphakama magnetic striction umphumela lokungeniswa ensimini, okubangela plate dlidliza wesifunda kazibuthe.

Transformer owodwa esigabeni yokwenza i voltage kushintshana for umthwalo value oyifunayo ngaphandle kokudinga ezintathu okhombisa ugesi.

transformer ngasinye siqukethe izingxenye ezimbili eziyisisekelo: core nocingo kubo akuyona esingaphansi kwezinsuku ezimbili. Umgomo we operation ilula. Ngenxa yalokho ezidlulayo kagesi ngokusebenzisa umqhubi eyinhloko emazombezombe, secondary eyenga amandla electromotive (EMF). Umnyombo siqukethe amapuleti ferromagnetic, isb ekugqugquzeleni impahla ekuqiniseni amandla kazibuthe (steel kagesi amamaki ezikhethekile).

Ubukhulu bale EMF kunqunywa ifomula:

E = 4,44 x F x f x ω

lapho:

F - amplitude of yokucucuza kazibuthe;

f - imvamisa wamanje;

ω - inani badedelane e emazombezombe.

I kuvunyelwe umthwalo umthamo, okuyinto "udonsa ingxenye" transformer owodwa isigaba, enikezwa kwesigaba izintambo, iziphi nilimaza ohlobo futhi kazibuthe wesifunda Q, ikakhulukazi permeability μ ferromagnetic. Ubukhulu core kanye nenani Windings ayisihloko ukubala, okuyinto evame isihloko umsebenzi Yiqiniso emayunivesithi lobuchwepheshe.

Kunoma ikuphi, namandla kakhulu owodwa esigabeni voltage transformer, umxhwele ngaphezulu yobukhulu bawo. Emzimbeni yabo ngokuvamile has a ilebula nge uhlu nemingcele eziyisisekelo (ovumelekile lamanje lokufaka futhi okukhipha voltages). Nokho, lokhu akusho ngaso sonke isikhathi kunjalo.

Ekusebenteni, abalungisi bethempeli abaningi babhekana nesidingo esikhundleni esesiphelile owodwa esigabeni voltage transformer. Ukuze uqinisekise nokufaneleka kumele bahlola izici zedivayisi, okuhlose esikhundleni.

Into yokuqala okufanele niyenze ukucacisa uvo emazombezombe. Ngezinye isinyathelo-phansi Transformers it has ukumelana enkulu.

Khona-ke, ukuyivala ku inethiwekhi, kungenzeka ukukala lo voltage okukhiphayo at lutho. Isilinganiso input bese okukhipha EMF kuyinto Coefficient ukuguqulwa K. Libuye amafraktjhini alinganayo Rin N. / N O., isb isibalo ematfuba ku Windings.

Ngemva kwalokho, njengoba umthwalo kungenziwa exhunywe ukumelana enamandla variable (Resistor) uphinde ususe izici zamanje yamandla aphindeke kabili ngokuchaza wamanje esinesilinganiso. Njengoba layisha kwandisa lo voltage okukhiphayo kancane kancane kunciphisa.

Transformers kukhona amandla hhayi kuphela, kodwa futhi ukulinganisa. Ezimweni lapho kubalulekile ukuchaza imali ethe zamanje esifundeni Usebenzisa ammeter. Ifakiwe ezinhlwini ngokulandelana, futhi kufanele ibe ukumelana ongaphakeme lihambisana ezinkulu cross-section ngezintambo magnetic kuka uhlelo. idivayisi okunjalo kuzobiza kakhulu futhi okukhulu, ngakho sebenzisa owodwa esigabeni transformers zamanje okuyinto susa kulingana encishisiwe value, futhi bebanika ukudla ezivamile ammeters serial. Bala amperage ilula, ihlala yodwa ukusebenzisa lezi zici emzimbeni.
