Transformer yam ua txhaum yam thiab ua rau pom

Cov hloov hluav taws xob yog tseem ceeb ntawm lub zog, kom muaj kev nyab xeeb thiab txuag hluav taws xob. Txawm li cas los xij, vim ntev - kev ua haujlwm, ib puag ncig kev nyuaj siab, thiab sab hauv cov txheej txheem nyuaj, transformers muaj kev cuam tshuam rau ntau yam kev ua txhaum. Nkag siab cov kev ua tsis zoo thiab lawv cov hauv paus ua rau tseem ceeb rau kev txhim kho kev cia siab thiab tiv thaiv kev tsis txaus siab.

1. Winding ua txhaum

Winding Luv Laugyog cov transformer ua txhaum. Cov tshwm sim thaum tus cwj pwm luv ntawm tig los yog rau hauv av, ua rau kev nrawm nrawm hauv qhov chaw tam sim no thiab mob hnyav dhau los. Xws li siab kub nrawm nrawm rwb thaiv tsev laus thiab muaj peev xwm txawm tias hluav taws kub. Tsis tas li ntawd, kev ua txhaum kom txo qis kev tawm tsam, cuam tshuam cov kev ua haujlwm sib xyaw ib txwm muaj.

Winding Qhib Cijkuj tseem muaj teeb meem tseem ceeb. Cov teeb meem tshwm sim suav nrog kev siv vuam txom nyem, tus neeg ua yeeb yam tsis zoo, lossis hlawv tawm ntawm lub sijhawm ntev- lub sij hawm overloading. Yog tias cov txheej txheem vuam thaum tsim khoom ua ntu zus, cov pob qij txha yuav ua kom xoob lossis disconnect thaum lub sijhawm ua haujlwm. Internal impurities lossis cov kab nrib pleb hauv cov khoom saib xyuas tuaj yeem ua rau cov tshuab tsis ua haujlwm, thaum lub sijhawm kub dhau los ntawm kev siv hluav taws xob tuaj yeem hlawv cov hlau. Qhib kev sib tw tsoo cov ntws ntawm hluav taws xob lub zog, uas ua rau muaj kev tawm tsam thiab tuaj yeem tsim hluav taws xob arcs uas muaj kev puas tsuaj txuas ntxiv.

2. Cov kev ua txhaum

Transformer tub ntxhais ua yuam kev tsuas yog suav multi -}} localမ်း ground groundingingောင်း thiab cov chaw ua haujlwm luv luv.

Ntau tus tseem ceeb hauv av ua txhaumFeem ntau kav los ntawm seem hlau, puas tsuaj rau lub rwb thaiv tsev txheej ntawm silicon lamination ntawm silicon lamination bolts lossis txhawb nqa ntas ua kev sib cuag nrog cov tub ntxhais. Cov kev ua txhaum no ua rau muaj kev sib tw ua kom sov siab, rwb thaiv tsev tawg, thiab kev laus sai sai. Thaum muaj mob hnyav, lawv tuaj yeem ua rau kev puas tsuaj loj.

Core core luv luvFeem ntau yog tshwm sim los ntawm qhov tsis zoo lossis kev puas tsuaj ntawm rwb thaiv tsev ntawm silicon cov roj lamination. Kev sib txuas lus muaj xws li ntev tau nphom rau hluav taws xob rog, thermal kev ntxhov siab, kev co, lossis kev puas tsuaj thaum lub sijhawm tu. Cov luv luv no nce Eddy ntws hauv thaj chaw muaj kev cuam tshuam, caij tsheb kub thiab thaum kawg rho tawm hloov kev ua haujlwm thiab lub neej.

3. Rwb thaiv tsev ua haujlwm

Lub rwb thaiv tsev system yog qhov tseem ceeb rau kev ua haujlwm hloov chaw. Rwb thaiv tsev tsis raws li feem ntau qeeb, ua rau muaj kev cuam tshuam los ntawm hluav taws xob, kev ntxhov siab, kev siv tshuab, kev sib xyaw.

Siab - voltage dej ib puag ncig hloov cov qauv txheej txheem nyob rau hauv cov ntaub ntawv rwb thaiv tsev, txo lub zog dielle. Ntau dhau ntawm cov kub uas tsis yog dissipated kom ceev nce rwb thaiv tsev laus. Neeg kho tshuab reeg thiab cov rog hluav taws xob tuaj yeem qhia cov kab nrib pleb lossis kev tsis huv, thiab cov roj av, thiab cov roj ntsha ua rau cov tshuaj yaig ntawm rwb thaiv tsev.

Cov tog dej noo yog qhov loj ntawm cov rwb thaiv tsev rwb thaiv tsev. Ua rau muaj xws li kev sib khi tsis zoo, ua tsis tau pa, lossis tsis txaus noo noo kev tiv thaiv thaum lub sijhawm saib xyuas. Thaum lub rwb thaiv tsev ua plamp, nws txoj kev tsis kam poob thiab dielectric kev pheej hmoo, nce kev pheej hmoo ntawm flashover lossis sab hauv luv luv.

4. Kais hloov pauv

On {{0} Click Download LOAD TAIS HLOOV HLOOV HLOOV (OLTCS) yog qhov tseem ceeb rau kev hloov pauv voltage hauv kev hloov pauv. Kev ua tsis ncaj ncees tuaj yeem cuam tshuam ntau yam cuam tshuam rau cov zis voltage ruaj khov thiab hloov kev ua haujlwm.

Ib qho teeb meem tsis zoo ntawm tus kais changer terminals. Cov oxidation, arcing thaum hloov, thiab hnav los ntawm kev ua haujlwm ntau ntxiv ua rau muaj kev sib cuag tiv thaiv. Tsis muaj kev sib tiv tauj lub siab lossis hlawv cov kab tiv tauj yuav ua rau muaj kev sib ze ua kom sov siab, muaj peev xwm ua rau tag nrho cov kais hloov pauv.

Lwm qhov teeb meem nquag yog kais ua haujlwm tsis zoo, feem ntau vim yog tsav tsheb malfunctions, watn iav Cheebtsam, lossis kev cuam tshuam kho tshuab thaum hloov. Lub cev muaj zog swb, kev sib txuas lus deformation, lossis iav backlash yuav tiv thaiv tus kais hloov mus txog nws txoj haujlwm tseeb. Qhov kev tsis zoo no tuaj yeem ua rau muaj kev tsis sib haum xeeb thoob plaws ntawm cov winding, muaj peev xwm ua rau muaj kev thaiv kev ua haujlwm tsis ua tiav.

5. Bushing swb

Transformer bushing tsis ua hauj lwm ua rau kev pheej hmoo ua hauj lwm tseem ceeb. Bushings ua hauj lwm siab li siab -}}}}}}}}}}}} pakhaum rwb thaiv tsev ntawm sab hauv thiab sab nraud yuav cuam tshuam kev nyab xeeb tam sim no.

Cov teeb meem uas tsis muaj teeb meem suav nrog cov av sib kis, cov kab tawg ntawm cov pob txha caj qaum, thiab roj so lossis dej noo vim qhov kev sib khi tsis zoo. Cov xwm txheej no txo ​​qis bushing lub zog dielrictric thiab thaum kawg coj mus rau flashersers lossis rwb thaiv tsev kev nyab xeeb, loj heev cuam tshuam kev nyab xeeb.

To taub thiab txheeb xyuas cov khoom sib pauv ntawm transformer - Cov teeb meem tsis txaus ntseeg, thiab bushing hloov pauv kev ntseeg tau thiab kev nyab xeeb ntawm lub zog hluav taws xob. Kev saib xyuas ib txwm, kev soj ntsuam kev mob, thiab kuaj mob kuaj yog qhov tseem ceeb kom tiv thaiv cov kev txhaum no thiab lub neej ntev.
