Cov ntsiab lus thiab cov txheej txheem ntawm kev xaiv tam sim no transformer
Mar 17, 2023| Thaum xaiv lub tshuab hluav taws xob hloov hluav taws xob, nws yuav tsum tau xaiv raws li txoj kev xaim thawj (xws li Y-hom kev sib txuas thiab V-hom kev sib txuas), qib kev siv hluav taws xob ntawm thawj qhov hluav taws xob, lub peev xwm ntawm cov kab thib ob, thiab cov kev cai rau kev hloov pauv raug.
Tam sim no transformers feem ntau yog sib sau ua ke nyob rau hauv sib txawv switchgears. Cov qauv ntawm cov transformers tam sim no txawv, thiab cov qauv ntawm tam sim no transformers feem ntau muaj qhov sib txawv loj (xws li tooj liab bar lapping daim ntawv, hlau core, duab, thiab lwm yam., thiab dynamic thiab thermal stability. Piv txwv li, tam sim no transformers nruab nrog lub hauv paus handcart txee feem ntau LZZBJ9 los yog AS12 qauv, tab sis muaj ntau yam qauv nruab nrog taag khoom.
Muaj ntau qhov sib txawv ntawm voltage transformers ntawm tib tus qauv thiab specification. Feem ntau, yuav muaj ntau yam kev sib txuas ua ke feem ntau yog vim qhov sib txawv ntawm kev hloov pauv, lub peev xwm ntawm cov coil thib ob, kev tiv thaiv coil thiab qhov tseeb ntawm cov metering kauj. Thaum xaiv qhov kev hloov pauv ntawm qhov hloov pauv tam sim no, qhov tseeb ntawm qhov ntsuas tam sim no yuav tsum tau txais ua ntej, thiab qhov tam sim no zoo dua ntawm 65 feem pua -85 feem pua ntawm qhov ntsuas qhov ntsuas tam sim no. Piv txwv li, yog tias qhov ntsuas tam sim no yog 70A, koj yuav tsum xaiv qhov hloov pauv hluav taws xob nrog qhov hloov pauv ntawm 100/5.
Tam sim no transformer transformer ratio yog 10{{10}}/5 (100/5 txhais tau hais tias thaum lub ntsiab tam sim no yog 100A, qhov thib ob tso zis tam sim no generated yog 5A Tus nqi no piav qhia txog tus nqi hloov pauv tus nqi, ntsuas qhov ntsuas tus nqi thiab cov nqi tso tawm. Tam sim no transformer thiab qhov hloov pauv ntawm ammeter yuav tsum tau xaiv. Kev ntsuas qhov tseeb tau cim rau ntawm daim ntawv teev npe ntawm lub tshuab hloov tam sim no, piv txwv li: 0.2 qib (kev ntsuas qhov tseeb yog 0.2 feem pua), Qib 0.5 ( ntsuas qhov yuam kev yog 0.5 feem pua). Yog tias qhov ntsuas tau tshaj qhov tam sim no, tej zaum yuav muaj qhov yuam kev loj nrog qhov tseeb tam sim no. Yog tias qhov siab dhau lawm nkag mus rau thaj tsam saturation ntawm lub hauv paus, cov ntaub ntawv ntsuas yuav tsis muaj nuj nqis.
