Cov ntaub ntawv hloov pauv feem ntau poob rau hauv ob pawg: cov ntaub ntawv tseem ceeb thiab cov khoom siv winding. Cov ntaub ntawv tseem ceeb feem ntau siv silicon steel los xij (tseem hu ua hluav taws xob hlau) vim lawv cov permeability siab thiab cov yam ntxwv tsis tshua muaj hlau, uas ua rau txo qis tam sim no poob thiab hysteresis poob, yog li txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Silicon steel sheets tau muab faib ua txias-rolled grain-oriented silicon steel (xws li 27QG100) thiab non-oriented silicon steel (xws li 50W470). Lub qub yog tsim rau siab - transformers efficiency, thaum lub tom kawg yog feem ntau siv nyob rau hauv me me thiab nruab nrab- loj transformers. Winding cov ntaub ntawv siv tooj liab lossis txhuas hlau. Copper xov hlau muaj cov conductivity zoo dua tab sis kim dua, thaum txhuas hlau yog lub teeb yuag thiab kev lag luam; Txawm li cas los xij, qhov sib txawv ntawm cov conductivity yuav tsum tau them nyiaj rau los ntawm kev nce tus ntoo khaub lig-sectional cheeb tsam. Tsis tas li ntawd, cov ntaub ntawv rwb thaiv tsev (xws li Nomex daim ntawv thiab epoxy resin) thiab cov xov xwm txias (cov roj ntxhia thiab SF6 gas) kuj yog cov ntaub ntawv tseem ceeb, cuam tshuam ncaj qha rau lub transformer qhov kub thiab txias ua haujlwm. Hauv cov xwm txheej tshwj xeeb, amorphous alloy cores (xws li hlau-raws li amorphous ribbon) tuaj yeem txo tsis muaj -load poob los ntawm ntau dua 70%, tab sis lawv lub zog siv tshuab qis dua. Tam sim no peb muaj transformer - tshwj xeeb kev co dampers hauv peb lub khw. Lawv yog ua los ntawm siab - cov ntaub ntawv zoo thiab kev cai -tsim kom haum rau ntau yam transformer installation scenarios, zoo txo cov suab nrov thiab kev co.
