Kev kuaj tshwj xeeb rau transformer yog dab tsi?

Kev ntsuam xyuas tshwj xeeb ntawm cov tshuab hloov pauv yog qhov kev sim siab dua uas tsis yog feem ntau ua raws li kev saib xyuas niaj hnub lossis thaum lub sijhawm tsim khoom. Cov kev ntsuam xyuas no feem ntau yog ua thaum muaj kev txhawj xeeb tshwj xeeb txog kev ua haujlwm ntawm transformer lossis thaum xav tau cov ntaub ntawv ntxaws ntxiv txog nws qhov xwm txheej. Nov yog qee qhov kev ntsuam xyuas tshwj xeeb tshaj plaws uas yuav ua tau ntawm transformers:

1.Sweep Frequency Response Analysis (SFRA): Qhov kev ntsuam xyuas no yog siv los kuaj xyuas cov kev hloov pauv ntawm cov zaus teb ntawm lub transformer vim winding deformation los yog lwm yam teeb meem.

2.Partial Discharge (PD) Test: Qhov kev ntsuam xyuas no yog siv los txheeb xyuas cov kev tso tawm ib nrab uas yuav qhia tau tias muaj kev ua txhaum ntawm cov rwb thaiv tsev.

3.Transformer Oil Analysis: Qhov kev ntsuam xyuas no yog siv los txheeb xyuas cov khoom ntawm cov roj transformer, xws li nws lub zog dielectric, cov ntsiab lus dej, acidity, thiab viscosity.

4.Dynamic Resistance Measurement: Qhov kev ntsuam xyuas no yog siv los ntsuas qhov dynamic tsis kam ntawm transformer windings nyob rau hauv load tej yam kev mob.

5.Impulse Voltage Withstand Test: Qhov kev ntsuam xyuas no yog siv los ntsuam xyuas lub peev xwm ntawm lub tshuab hluav taws xob rwb thaiv tsev kom tiv taus qhov siab voltage impulses.

6.Heat Run Test: Qhov kev ntsuam xyuas no yog siv los ntsuas qhov kev ua haujlwm ntawm lub tshuab hluav taws xob hauv kev ua haujlwm los ntawm kev ua haujlwm rau lub sijhawm ntev.

7.Short Circuit Withstand Test: Qhov kev ntsuam xyuas no yog siv los txiav txim siab lub peev xwm ntawm lub tshuab hluav taws xob tiv thaiv luv luv Circuit Court txhaum.

Cov kev ntsuam xyuas no feem ntau ua los ntawm cov tuam txhab kuaj tshwj xeeb lossis los ntawm cov chaw tsim khoom ntawm lub tshuab hloov pauv. Cov txiaj ntsig ntawm cov kev ntsuam xyuas no tuaj yeem muab cov ntaub ntawv tseem ceeb hais txog qhov xwm txheej ntawm lub tshuab hloov pauv thiab pab txheeb xyuas cov teeb meem uas muaj peev xwm ua ntej lawv ua rau muaj teeb meem loj dua. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov kev ntsuam xyuas tshwj xeeb ua tau tuaj yeem sib txawv nyob ntawm seb hom thiab qhov loj ntawm lub transformer, nrog rau cov kev txhawj xeeb tshwj xeeb lossis cov kev xav tau ntawm qhov system nws yog ib feem ntawm.
