Yam khoom twg yog siv los ua cov tub ntxhais ntawm lub hwj chim transformer
Fais fab transformers yog cov khoom tseem ceeb hauv hluav taws xob hluav taws xob uas hloov hluav taws xob hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov los ntawm electromagnetic induction. Cov transformers fais fab no muaj ntau yam khoom xws li windings, rwb thaiv tsev, tso tsheb hlau luam, thiab cov tub ntxhais. Lub hauv paus ntawm lub hwj chim transformer yog ib qho tseem ceeb ntawm cov khoom uas yog lub luag hauj lwm rau kev yooj yim rau kev hloov ntawm lub zog kom zoo. Feem ntau, cov tub ntxhais yog tsim los ntawm cov khoom sib txawv, tab sis cov khoom siv feem ntau siv los ua cov tub ntxhais ntawm lub zog hloov hluav taws xob yog laminated silicon steel.
Laminated silicon steel muaj ntau yam khoom tsim nyog uas ua rau nws yog cov khoom zoo meej rau kev tsim cov tub ntxhais transformer. Ib qho ntawm cov yam ntxwv tseem ceeb ntawm laminated silicon steel yog nws qhov siab sib nqus permeability, ua rau nws yooj yim dua rau magnetize thaum hluav taws xob tam sim no dhau los ntawm transformer windings. Lub siab permeability ntawm cov khoom yuav txo tau lub zog poob, kom ntseeg tau tias lub transformer ua hauj lwm zoo.
Lwm qhov tseem ceeb ntawm cov laminated silicon steel yog nws qhov poob qis hysteresis. Hysteresis poob yog hais txog lub zog dissipated nyob rau hauv cov khoom raws li nws undergoes dua magnetization cycles thaum lub sij hawm transformer lub lag luam. Qhov qis hysteresis poob ntawm laminated silicon steel minimizes zog poob thiab ua kom lub neej ntev ntawm lub transformer.
Cov laminations ntawm silicon steel core yog insulated los ntawm ib leeg siv oxide lossis lacquer txheej thaum lub sijhawm tsim khoom. Cov txheej rwb thaiv tsev rhuav tshem cov eddy tam sim no uas tuaj yeem ua rau lub zog poob hauv transformer cores.
Txawm hais tias laminated silicon steel yog cov khoom siv feem ntau siv rau cov cores transformer, lwm cov ntaub ntawv xws li amorphous hlau lossis ferrites kuj siv. Amorphous hlau yog qhov zoo tagnrho rau cov ntawv thov uas xav tau ntau zaus, xws li hloov-hom fais fab mov thiab lub laptop chargers. Ferrites, ntawm qhov tod tes, yog qhov zoo rau kev tawm tsam ntawm lub suab nrov hauv hluav taws xob.
Hauv kev xaus, kev xaiv cov khoom siv tseem ceeb rau lub zog hloov hluav taws xob nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov. Txawm li cas los xij, laminated silicon steel yog cov khoom siv feem ntau siv vim nws muaj ntau yam khoom tsim nyog uas ua kom muaj kev ua haujlwm zoo thiab kev ua haujlwm ntev ntawm lub transformer.
