Cov khoom siv nrov heev feem ntau yog qhov tsis zoo, tab sis nws kuj tuaj yeem ua rau muaj kev nyab xeeb. Transformers nquag tawm suab nrov lossis nrov nrov, txawm hais tias qhov no tsis tas yuav qhia txog kev ua haujlwm tsis zoo; lub hum tuaj yeem yog ib qho kev qhia ntawm kev ua haujlwm ib txwm muaj thiab kev ua haujlwm sib nqus. Txawm li cas los xij, txij li lub suab nrov ntawm lub tshuab hluav taws xob ntau dhau tuaj yeem cuam tshuam rau cov chaw ua haujlwm thiab cov chaw pej xeem, kev nkag siab txog qhov ua rau pab txo qis cov hum thiab nws cov teebmeem.
Dab tsi ua rau Transformers rau Hum?
Magnetostriction yog thawj qhov ua rau lub suab nrov ntawm transformer. Nws yog hais txog qhov tshwm sim uas cov ntaub ntawv ferromagnetic nthuav dav thiab cog lus nyob rau hauv kev cuam tshuam ntawm magnetic teb. Molecules elongate thaum lub magnetic teb tau thov thiab cog lus rov qab mus rau lawv qhov qub qub thaum lub teb raug tshem tawm. Transformers tsim magnetic excitation los ntawm alternating voltage thiab tam sim no. Qhov kev sib nqus no ua rau cov hlau nplaum sib nqus- cov kab sib nqus ntawm cov khoom siv. Qhov loj dua qhov sib nqus flux thov rau lub transformer, qhov ntau pronounced lub magnetostriction thiab ua suab nrov.
Lub transformer lub hauv paus muaj ntau cov hlau nplaum laminations uas nthuav thiab cog lus nyob rau hauv teb rau cov generated magnetic teb. Txhua lub voj voog magnetization muaj ob qhov kev nthuav dav zoo li no -kev sib cog lus; Yog li ntawd, lub transformer ua hauj lwm ntawm 60 Hz undergoes 120 cycles ntawm expansion thiab contraction ib ob. Tus nqi no txiav txim siab lub suab nrov zaus.
Cov kev txav no tsis tshwm sim tsis sib xws tab sis tuaj yeem pom qhov hloov pauv tsis tu ncua, ua rau lub tshuab hluav taws xob tawm suab nrov ntawm cov zaus uas muaj ntau qhov sib txawv ntawm qhov tseem ceeb. Thaum cov kev txav no yog microscopic thiab pom tsis pom ntawm qhov muag liab qab, lawv txaus los tsim kev co thiab suab nrov.
Lwm yam uas ua rau lub suab nrov transformer muaj xws li:
Kev laus: Raws li lub hnub nyoog hloov pauv, cov khaubncaws sab nraud povtseg hauv cov tub ntxhais yuav pib sib cais, ua kom lub suab nrov thaum lub sijhawm vibration.
Kiv cua: Qhov cua sov ntau ntawm lub tshuab hloov hluav taws xob tsim tawm, cov kiv cua txias ntau yuav tsum tau ua. Cov kiv cua no kuj ua rau lub suab nrov tag nrho uas tsim thaum lub sijhawm ua haujlwm.
Windings: Transformer windings kuj nthuav dav thiab cog lus hauv cov lus teb rau cov hluav taws xob tam sim no, ntxiv rau cov suab nrov ntawm lub kaw lus. Cov no tsuas yog ob peb lub laj thawj vim li cas koj yuav tsum yuav siab - transformers zoo; lawv txo qis kev tsim hluav taws xob thiab kev ntxhov siab thaum nyob hauv qhov zoo rau ntau xyoo.
Thaum Transformer Suab nrov dhau los ua qhov teeb meem
Lub suab nrov tas li feem ntau yog ib qho cim qhia tias lub tshuab hloov pauv tau ua haujlwm ib txwm, tab sis lwm yam suab nrov yuav qhia tau tias muaj teeb meem yuav tsum tau saib xyuas tam sim. Paub txog cov cim ceeb toom no tuaj yeem tiv thaiv kev puas tsuaj, txhim kho kev nyab xeeb ntawm cov neeg ua haujlwm, thiab ua kom cov cuab yeej siv tau ntev. Cov neeg ua haujlwm tu thiab cov kws tshaj lij yuav tsum paub paub qhov txawv ntawm cov suab ib txwm muaj thiab cov teeb meem kev ua haujlwm.
Ceeb Toom Qhia Tshaj Tawm
Yog tias koj pom ib qho ntawm cov suab hauv qab no, nws yog qhov zoo tshaj los tshawb xyuas ntxiv lossis hu rau tus kws tshaj lij kom paub qhov tseeb:
Crackling, Popping, los yog Hissing suab
Cov suab nrov tsis meej no feem ntau cuam tshuam thiab yuav qhia tau tias muaj teeb meem hluav taws xob loj. Lawv feem ntau taw qhia rau ib feem ntawm qhov tso tawm, arcing, lossis kev puas tsuaj hauv qhov hloov pauv.
Kev tso tawm ib nrab yog hais txog kev sib tsoo hluav taws xob hauv cheeb tsam hauv lub rwb thaiv tsev; nws degrades rwb thaiv tsev kev ua tau zoo thiab tuaj yeem ua rau tsis ua haujlwm. Arcing yog ib hom kev tawm paug ntau dua uas ua rau muaj qhov kub thiab txias thiab ua rau cov khoom puas tsuaj sai. Cov suab nrov kuj tseem tuaj yeem qhia qhov nkag ntawm cov dej noo los yog cov khoom paug rau hauv cov roj, ua rau hluav taws xob xau.
Kev hnov cov suab no txhais tau hais tias muaj peev xwm ua txhaum loj, thiab koj yuav tsum tshuaj xyuas cov cuab yeej tam sim ntawd.
Gurgling lossis Bubbling Sounds
Thaum lub suab gurgling thiab bubbling tej zaum yuav zoo li tsis tshua ceeb tshaj li crackling los yog hissing, lawv tseem ceeb txaus siab, tshwj xeeb tshaj yog nyob rau hauv roj -immersed ncoo- mounted transformers. Cov suab nrov no feem ntau qhia txog teeb meem nrog lub tshuab ua kom txias lossis muaj cov pa roj npuas hauv cov roj hloov pauv. Kev tsim npuas tuaj yeem tshwm sim los ntawm overheating, roj degradation, los yog huab cua nkag mus rau hauv lub cev vim muaj qhov xau.
Npuas tuaj yeem txo cov roj cov khoom siv hluav taws xob thiab ua rau qee qhov tso tawm lossis flashover. Gurgling suab kuj tseem qhia tau hais tias muaj teeb meem nrog lub twj tso kua mis roj los yog lub voj voog, cuam tshuam rau lub tshuab hluav taws xob ua kom txias txias.
Loud Bangs lossis Thumping Sounds
Tam sim ntawd, nrov nrov los yog lub suab nrov nrov yog qhov qhia tau tias muaj kev ua haujlwm tsis zoo. Cov suab nrov zoo li no tuaj yeem tshwm sim los ntawm xoob windings, hloov cov tub ntxhais laminations, lossis cov khoom siv sab hauv. Yog tias sab laug tsis kho, qhov ua rau muaj kev ntxhov siab tuaj yeem ua rau muaj kev puas tsuaj rau cov rwb thaiv tsev, luv luv Circuit Court, lossis txawm tias tag nrho cov khoom siv tsis ua haujlwm.
Kev hnov cov suab no qhia tias muaj peev xwm ua txhaum loj hauv sab hauv; cov cuab yeej yuav tsum raug kaw tam sim ntawd thiab tshuaj xyuas los ntawm cov kws paub txog kev paub.
Hloov hauv Pitch lossis Tone
Txawm tias ib txwm hum ua lub cim ceeb toom yog tias nws lub suab lossis lub suab hloov pauv loj heev. Kev nce tam sim ntawd ntawm qhov ntim lossis qhov txawv txav hauv lub suab yuav qhia tau tias overload, voltage fluctuations, lossis kev puas tsuaj rau cov khoom sab hauv.
Piv txwv li, nce magnetic flux ceev tshwm sim los ntawm ntau tshaj - excitation intensifies magnetostriction effect, ua rau lub suab nrov. Ib yam li ntawd, xoob core clamping lossis kev laus rwb thaiv tsev tuaj yeem ua rau muaj kev vibration. Yog hais tias tus paub hum ua nrov nrov los yog tsis raug, nws qhia tau hais tias lub transformer nyob rau hauv qhov txawv txav kev nyuaj siab.
Yog tias koj hnov cov suab ceeb toom no, nws yog qhov zoo tshaj rau hu rau tus kws kho mob uas tsim nyog rau kev ntsuam xyuas thiab kev pom zoo. Kev tshawb nrhiav ntxov thiab kev cuam tshuam tuaj yeem tiv thaiv cov teeb meem me me los ntawm kev nce mus rau qhov ua tsis tiav loj, yog li txuas ntxiv cov cuab yeej siv lub neej.
Union Power muaj ntau yam ntawmqhuav-hom thiab pad-mounted transformers.Tsim los ntawm cov khoom siv zoo - zoo, peb cov transformers pab tswj cov suab nrov tsawg rau xyoo tom ntej.
