1. Initial Visual Inspection: Saib xyuas lub hwj chim connector rau looseness los yog deformation, lub hwj chim qaum rau kev puas tsuaj, thiab xyuas cov cua fuses. Saib rau tej yam tsw ntxhiab tsw, bulging, los yog blackened marks ntawm cov khoom nyob rau hauv lub hwj chim mov cheeb tsam ntawm lub casing.
2. Kev Ntsuas Ntsuas: Siv lub ntsuas ntsuas ntsuas ntsuas qhov ntsuas hluav taws xob kom ntseeg tau tias nws nyob hauv qhov ntsuas ntsuas. Tom qab ntawd, ntsuas qhov DC tso zis voltage ntawm lub hwj chim board. Yog hais tias tus nqi deviates los ntawm ntau tshaj ± 10%, lub zog module puas lawm.
3. Cov tsos mob tsis zoo: Yog tias lub cuab yeej tsis muaj lus teb, nquag fuse tshuab tawm, lub zog tso zis tsis txaus, lossis qhov tsis zoo ntawm cov khoom siv hluav taws xob thiab lub suab nrov hauv cheeb tsam fais fab, thiab cov teeb meem ntawm cov khoom siv hluav taws xob sab nraud tau raug txiav tawm, cov khoom siv hluav taws xob yuav ua rau muaj qhov tsis zoo.
4. Daim Ntawv Pov Thawj Hloov Cov Khoom Siv: Hloov cov thawj lub hwj chim board nrog ib tug paub zoo ntawm cov qauv zoo tib yam. Yog tias lub cuab yeej rov qab mus ua haujlwm li qub, cov khoom siv hluav taws xob qub yog 100% lees paub tias ua yuam kev.
