Transformer test labs siv cov cuab yeej ntsuas qib siab thiab thev naus laus zis los xyuas kom meej tias cov transformers ua tau raws li qhov xav tau kev ua tau zoo. Lawv kuj muaj cov neeg ua haujlwm tau txais kev cob qhia zoo uas tuaj yeem ua cov ntawv xeem thiab txhais cov txiaj ntsig tau raug. Cov ntawv ceeb toom raug tsim tawm tom qab txhua qhov kev xeem, thiab lawv suav nrog cov txheej txheem xeem, cov txiaj ntsig, thiab cov lus pom zoo rau txhua qhov kev hloov kho tsim nyog.
Thaum nws los txog rau kev sim transformer nyob rau hauv ib cheeb tsam chaw kuaj, muaj ntau ntau yam sib txawv ntawm cov khoom xeem uas yuav ua tau kom lub transformer ua hauj lwm zoo. Cia peb ua tib zoo saib qee yam ntawm cov khoom xeem uas tuaj yeem ua tau hauv lub chaw kuaj sim transformer.
1. Turns Ratio Test: Qhov kev ntsuam xyuas no txiav txim siab qhov sib piv ntawm qhov hloov pauv kom ntseeg tau tias qhov hluav taws xob tau hloov pauv kom raug. Qhov kev sim no suav nrog kev siv qhov hluav taws xob mus rau ib qho winding ntawm lub transformer thiab ntsuas qhov tshwm sim voltage ntawm lwm qhov winding.
2. Insulation Resistance Test: Qhov kev ntsuam xyuas no ntsuas qhov rwb thaiv tsev ntawm cov windings thiab cov tub ntxhais ntawm lub transformer. Los ntawm kev ntsuas qhov kev tiv thaiv, qhov kev ntsuam xyuas no tuaj yeem txiav txim siab seb puas muaj cov teeb meem cuam tshuam nrog kev rwb thaiv tsev, xws li ya raws lossis kev sib kis.
3. Transformer Oil Analysis: Transformer roj yog ib qho tseem ceeb ntawm cov transformer thiab pab kom insulate thiab txias lub transformer. Qhov kev sim no suav nrog kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg ntawm cov roj kom ntseeg tau tias cov roj huv si thiab tsis degraded.
4. DC Resistance Test: Qhov kev ntsuam xyuas no ntsuas qhov kev tiv thaiv ntawm cov transformer windings siv ncaj qha tam sim no. Qhov kev sim no tuaj yeem pab txheeb xyuas txhua yam teeb meem nrog cov xaim lossis windings ntawm transformer.
5. Short Circuit Test: Qhov kev ntsuam xyuas no yog ua los txiav txim qhov impedance ntawm lub transformer thaum nws raug rau ib tug luv luv Circuit Court. Qhov kev sim no tuaj yeem pab txheeb xyuas cov teeb meem uas muaj peev xwm nrog lub tshuab hloov pauv lub peev xwm los daws cov teeb meem txhaum cai.
6. Qhov kev ntsuam xyuas tseem ceeb hauv cov chaw sim no yog "kev sim ntsuas", uas simulates ib puag ncig hnyav xws li xob laim. Qhov kev sim no suav nrog kev siv lub siab-voltage impulse rau lub transformer windings thiab ntsuas nws cov lus teb. Qhov kev sim no txiav txim siab Transformer lub peev xwm los tiv thaiv qhov hluav taws xob thiab muab kev ntseeg siab rau kev ua haujlwm thaum muaj xwm txheej xob laim.
Kev ntsuam xyuas transformer yog ib feem tseem ceeb ntawm kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm transformers hauv cov tshuab fais fab. Los ntawm kev ua cov kev ntsuam xyuas no hauv chav kuaj transformer, nws muaj peev xwm txheeb xyuas cov teeb meem uas muaj peev xwm ua ntej lawv ua kev puas tsuaj loj, ua rau kev txhim kho kev ntseeg siab thiab kev nyab xeeb.
