Routine Test ntawm Distribution Transformer
Fais fab transformers yog ib qho tseem ceeb ntawm cov hluav taws xob faib hluav taws xob uas hloov hluav taws xob hluav taws xob los ntawm qhov siab mus rau qib qis thiab muaj lub luag haujlwm xa hluav taws xob rau cov neeg siv khoom hauv tsev, kev lag luam, thiab kev lag luam. Txhawm rau kom ntseeg tau tias kev lag luam txhim khu kev lag luam ntawm cov khoom siv hluav taws xob faib khoom, kev sim niaj hnub ua kom pom cov teeb meem lossis qhov tsis xws luag.
Qhov kev sim niaj hnub ntawm kev faib cov khoom siv hluav taws xob muaj xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob uas tau ua los ntawm cov khoom siv hluav taws xob tshiab ua ntej lawv muab tso rau hauv kev pabcuam thiab ntawm cov khoom siv hluav taws xob uas twb muaj lawm thaum kho lossis tshuaj xyuas. Cov kev xeem no feem ntau suav nrog cov qauv tsim los ntawm cov koom haum thoob ntiaj teb xws li International Electrotechnical Commission (IEC) thiab Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob thiab Hluav Taws Xob (IEEE).
Cov hauv qab no yog qee qhov kev sim ua tau zoo ntawm kev faib khoom transformers:
1. Kev ntsuas kev tiv thaiv hluav taws xob: Qhov kev ntsuas no ntsuas qhov kev tiv thaiv ntawm lub tshuab hluav taws xob rwb thaiv tsev ntawm windings thiab hauv av. Nws pab tshawb xyuas qhov rwb thaiv tsev theem ntawm transformer thiab txiav txim siab seb nws puas haum rau kev ua haujlwm.
2. Transformer lem ratio test: Qhov kev ntsuam xyuas no ntsuas qhov sib piv ntawm tus naj npawb ntawm cov lem ntawm qhov siab thiab qis voltage windings ntawm lub transformer. Nws yog ib qho tseem ceeb rau kev ntsuam xyuas raws li nws pab kom paub tseeb tias lub transformer muaj peev xwm hloov tau qhov voltage los ntawm cov theem siab mus rau theem qis uas yuav tsum tau rau kev ruaj ntseg.
3. Kev ntsuas qhov sib nqus sib nqus: Qhov kev sim no txheeb xyuas qhov sib luag thiab sib xws ntawm cov hlau nplaum sib nqus ntawm cov coils. Nws pab txhawm rau txheeb xyuas qhov tsis xws luag, suav nrog winding malfunction thiab core distortion.
4. Load poob thiab tsis-load poob kev xeem: Qhov kev ntsuam xyuas no ntsuas lub transformer efficiency thiab poob ntawm tag nrho load thiab tsis muaj load. Nws yog ib qho tseem ceeb heev uas yuav pab txiav txim seb lub zog poob nyob rau hauv lub transformer thiab nws cov nqi khiav hauj lwm.
5. Kev ntsuas luv luv Circuit Court impedance: Qhov kev sim no txiav txim siab lub tshuab hluav taws xob muaj peev xwm tiv thaiv hluav taws xob luv luv los ntawm kev ntsuas nws impedance rau qhov txhaum tam sim no. Nws yog ua los xyuas kom muaj kev nyab xeeb ntawm cov cuab yeej siv thiab ib puag ncig ib puag ncig.
Hauv kev xaus, cov kev ntsuam xyuas niaj hnub ntawm cov khoom siv hluav taws xob faib hluav taws xob yog qhov tseem ceeb los xyuas kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob. Cov kev ntsuam xyuas no pab txhawm rau txheeb xyuas thiab tiv thaiv qhov tsis xws luag lossis tsis zoo ua ntej lawv ua rau muaj kev puas tsuaj lossis cuam tshuam rau lub cev. Yog li ntawd, nws yog ib qho tseem ceeb uas cov kev ntsuam xyuas no tau ua tsis tu ncua thiab ua tib zoo xyuas los ntawm cov kws tshaj lij los tswj kev ncaj ncees ntawm daim phiaj hluav taws xob thiab kom txo qis qis thaum muaj kev ua txhaum lossis kev saib xyuas.
