Hauv cov hluav taws xob hloov pauv, tuscov tseem ceeb hauv avyog qhov tseem ceeb ntawm kev tsim qauv thiab kev ua haujlwm. Tus hloov pauv hloov pauv, feem ntau ua los ntawm laminated silicon steel, yog yuav tsum tau cog grolicon, tab sis nrog ib qho xwm txheej tshwj xeeb: nws yuav tsum tau cog rau hauvtsuas yog ib kisCov. Qhov yuav tsum tau ua yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov hloov pauv. Hauv qab no, peb tshawb nrhiav cov laj thawj tom qab tus qauv tsim qauv.
1. Tiv thaiv cov kab mob ncig ua si
Lub ntsiab lus tseem ceeb rau hauv av Tus hloov pauv hloov ntawm tsuas yog ib kis yog kom zamCwj txoj kev ncig xyuasCov. Yog tias cov tub ntxhais tau cog rau ntau cov ntsiab lus, lub voj kaw kaw tau ntawm cov ntsiab lus av. Lub voj no tuaj yeem ua raws li kev txhaj tshuaj thib ob, ua rau muaj kev sib tw vim muaj kev sib nqus gravetic flux hauv cov tub ntxhais. Cov kab ncig no tuaj yeem ua rau:
Nce kev poob: Circulating cov dej ntws tawm ua rau cov cua sov ntxiv, txo cov hloov pauv tau zoo.
Overheating: Cua sov ntau dhau tuaj yeem ua kev puas tsuaj rau cov tub ntxhais thiab rwb thaiv tsev, ua rau kev ua tiav ntxov.
Txoj kev ua haujlwm tseem ceeb: Circulating cov dej ntws tawm tuaj yeem cuam tshuam cov sib nqus flux, muaj feem ua rau cov tseem ceeb tshaj plaws thiab ua haujlwm ruaj khov.
Los ntawm grounding cov tub ntxhais ntawm tsuas yog ib kis, tsim ntawm cov loops yog tiv thaiv, tshem tawm cov kev pheej hmoo ntawm kev ncig ua si.
2. Xyaum kev nyab xeeb
Prounding lub transformer core yog qhov tsim nyog rau kev nyab xeeb. Cov tub ntxhais muaj peev xwm sib sau cov nqi zoo li qub vim lub tshuab hluav taws xob hauv lub sijhawm ua haujlwm. Tsis muaj av hauv av, cov nqi no tuaj yeem tsim kom muaj cov qib txaus ntshai, cov kev pheej hmoo ntawm cov kev pheej hmoo xws li:
Lub zog hluav taws xob: Cov neeg ua haujlwm ua haujlwm lossis nyob ze ntawm cov hloov pauv tuaj yeem raug rau cov kev tsim hluav taws xob siab.
Lub cev: Kev tswj hwm kev tawm paug ntawm hluav taws xob zoo li qub tuaj yeem ua rau arcing, ua kom lub hloov pauv lossis cov khoom siv puag ncig.
Ib qho ib qho -}}}} Tshaj tawm cov kab nrees kom muaj kev phom sij ntawm lub ntiaj teb, txo qis kev pheej hmoo no.
3. Zam kev puas tsuaj tseem ceeb
Ntau cov ntsiab lus av tau tuaj yeem tsim cov kab hluav taws xob tsis muaj hluav taws xob, ua rau muaj cua sov hauv zos thiab muaj peev xwm ua rau cov tub rog Lamination. Qhov no tuaj yeem ua rau:
Rwb thaiv tsev kev puas ntsoog: Cua sov ntau dhau yuav ua rau lub rwb thaiv tsev ntawm cov tub rog tub rog, txo tus hloov pauv kev ua tau zoo.
Mechanical kev ntxhov siab: Cov cua sov tsis ncaj yuav ua rau cov neeg kho tshuab distortion ntawm cov qauv tseem ceeb.
Ib Leeg -}}}}}}}}}}} Cov teeb meem los ntawm kev ua kom muaj peev xwm ua kom muaj kev ntxhov siab ntxiv thiab tsis yog.
4. Qhov yoojyim ua txhaum cai paub
In the event of a fault, such as a short circuit or insulation failure, a single-point grounding system makes it easier to identify and locate the problem. Ntau cov ntsiab lus av ua kom tsis raug cai los ntawm kev tsim cov parallel paths, ua rau nws nyuaj rau kev kuaj pom qhov tseeb.
5. Ua raws li cov qauv
Cov qauv hluav taws xob thiab cov cai hluav taws xob, xws li cov txheej txheem hluav taws xob thiab IEC (JeCent Electrotics Commission), yuam kev ib leeg {{}}} {point pores rau transformer cores. Ua raws li cov qauv no kom ntseeg tau tias kev hloov pauv tau muaj kev nyab xeeb, kev ntseeg tau, thiab cov kev ua tau zoo.
Kev siv ntawm ib qho -}} point grounding
Hauv kev xyaum, ib leeg {{-}}}} Tshaj tawm cov tub ntxhais ua tiav los ntawm kev hloov pauv ntawm cov av uas tau mob siab rau cov pob zeb. Qhov kev sib txuas no ib txwm ua rau qhov chaw yooj yim, xws li cov tub ntxhais clamp lossis thav duab, thiab yog tsim los kom ntseeg tau tias feem ntau tsis kam thiab muaj kev sib cuag.
