Kev ntsuas thiab ntsuas kev ua tau zoo
Tom qab koj nruab ib tug split core tam sim no transformer, koj yuav tsum xyuas kom meej tias nws ua hauj lwm raws li xav tau. Kev sim thiab txheeb xyuas qhov ua tau zoo pab koj ntes cov teeb meem ntxov thiab ua kom koj lub cev nyob nyab xeeb thiab raug. Koj tuaj yeem ua raws li cov kauj ruam tseem ceeb no txhawm rau txheeb xyuas koj lub transformer:
- Ntsuas ntsuas
Koj piv cov tam sim no ntawm thawj sab nrog rau tam sim no nyob rau theem nrab. Qhov kev ntsuam xyuas no qhia tau hais tias lub transformer muab qhov tseeb tso zis. Yog tias qhov piv txwv tsis raug, koj qhov kev nyeem ntawv yuav tsis raug. - Polarity Test
Koj xyuas cov kev taw qhia ntawm windings. Cov kauj ruam no ua kom paub tseeb tias tam sim no ntws txoj hauv kev los ntawm transformer. Yog tias koj txuas qhov polarity tsis raug, koj qhov ntsuas tuaj yeem rov qab los yog tsis raug. - Excitation (Saturation) Test
Koj nce qhov voltage thiab saib thaum lub transformer core pib saturate. Lub "lub hauv caug taw tes" yog qhov uas cov tub ntxhais tsis tuaj yeem tuav tam sim no ntau dua. Qhov kev sim no yuav pab koj paub txog qhov txwv ntawm koj lub transformer. - Rwb thaiv tsev Resistance Test
Koj ntsuas qhov rwb thaiv tsev tiv thaiv cov windings zoo npaum li cas. Kev rwb thaiv tsev zoo ua rau koj muaj kev nyab xeeb ntawm hluav taws xob poob siab thiab tiv thaiv kev luv luv. - Winding Resistance Test
Koj txheeb xyuas qhov tsis kam ntawm cov transformer windings. Yog tias qhov kev tiv thaiv siab dhau los yog qis dhau, lub transformer yuav muaj teeb meem sab hauv. - Burden Test
Koj txuas lub transformer rau nws cov load load thiab saib seb nws ua hauj lwm nyob rau hauv ib txwm tej yam kev mob. Qhov kev ntsuam xyuas no qhia tau hais tias lub transformer tuaj yeem tswj cov cuab yeej koj npaj yuav siv.
Tswv yim:Nco ntsoov sau koj cov txiaj ntsig kev xeem. Khaws cov ntaub ntawv zoo pab koj pom cov kev hloov pauv lossis teeb meem yav tom ntej.
