Thaum siv series resonance nyob rau hauv lub tshav pob tiv thaiv voltage test, vim li cas qee zaum qhov resonance point tsis pom? Peb xaus raws li nws tus kheej xyoo ntawm kev paub. Cov laj thawj tseem ceeb yog raws li nram no:
1, lub resonance point ntawm lub cuab yeej tshaj qhov tso zis ntau zaus ntawm tus tswv tsev;
2, muaj qhov yuam kev hauv kev xaim ntawm cov cuab yeej kuaj;
3, cov cuab yeej tsis tuaj yeem ntseeg tau ua ntej kev xeem;
4, high-voltage sampling tawm tswv yim teeb liab yog qhib los yog unreliable;
5. Cov qauv yog faulty.
Dab tsi tuaj yeem raug tshem tawm
1. Ua tib zoo xyuas ua ntej lub sijhawm tiag tiag kom pom tias cov khoom siv hauv av thiab yog tias muaj qhov tawg ntawm cov xaim hauv av;
2, xyuas qhov on-off ntawm lub siab thiab qis voltage coils ntawm excitation transformer;
3. Tshawb xyuas seb cov kab hluav taws xob reactor puas yog lawm.
4, xyuas qhov txuas ntxiv ntawm cov kab hluav taws xob faib hluav taws xob;
5, xyuas qhov txuas ntxiv ntawm qhov siab thiab qis voltage capacitor caj npab ntawm qhov voltage divider;
6. Tsis muaj qhov taw tes resonance thaum lub cuab yeej txhawb nqa, thiab lub on-off ntawm cov nyiaj capacitor yuav tsum tau kuaj xyuas.
