Network transformers yog siv los ua cov hloov ntawm voltage hauv ntau yam khoom siv. Thaum ua cov cuab yeej hauv tsev, nws tsim nyog los xaiv lub tshuab hloov pauv nrog cov tsis tsim. Ua ntej ntsuas cov ntsuas hluav taws xob tawm, nws yog qhov tsim nyog yuav tsum nrhiav kom pom qhov sib hloov ua ntej kom koj thiaj li txuas tau qhov hloov pauv mus rau hauv lub network.
Tsim nyog
- - Lub teeb loj muaj zog hauv lub laub ntawv;
- - multimeter.
Cov Lus Qhia

Txheeb xyuas qhov hloov hluav taws xob kom zoo. Ntawm qee tus qauv hloov pauv, cua tau kos npe rau ntawm txheej sab saum toj ntawm insulating ntawv thiab cov lus sib txuam tau sau npe. CCI transformers yog ua tiav nrog ib cov chaw ntsuab, lawv tseem hu ua kev hloov pauv tub rog. Lawv sau cov cim rau ntawm lawv, uas yog nyob rau hauv phau ntawv hais txog rau kev hloov pauv, thiab suav lej cov lus xaus ntawm cov kab hlau. Pom cov thawj kev sib hloov ntawm lub tshuab hloov hluav taws xob los ntawm lub suab txuas lossis hluav taws xob qis hluav taws xob tau yooj yim heev - nws tau ua nrog xaim ntawm ntu me dua li qhov sib hloov theem ob. Koj tuaj yeem pom qhov pib sib hloov ntawm lub tshuab hluav taws xob qis los ntawm cov khoom siv los ntawm kev ntsuas qhov tsis kam ntawm txhua qhov thaiv. Cov winding nrog qhov kev tawm tsam loj tshaj plaws yuav yog thawj lub winding.

Kev siv tshuab hluav taws xob muaj zog ntau ntawm TAN hom tau siv rau ntawm cov khoom siv teeb khoom qub. Qhov tsis kam ntawm lawv cov high voltage hluav taws xob sib txawv txawv insignificantly, thiab tus nqi ntawm qhov winding tsis tuaj yeem txiav txim siab qhov tsis txaus ntseeg uas cua yog qhov tseem ceeb. Txhawm rau kom pom thawj qhov kev hloov ntawm lub tshuab hluav taws xob zoo li no, ntsuas qhov tsis kam ntawm txhua qhov ntsuas cua thiab sau qhov tseem ceeb uas tau txais ntawm daim ntawv, tseem sau tseg cov lej ntawm lawv cov terminals. Cov windings uas nws qhov cuam tshuam txog xoom yog qhov tsawg-voltage windings tsim los ua kom lub zog ntawm qhov tseeb ntawm cathodes ntawm cov xov tooj cua. Cov seem windings tuaj yeem kuaj xyuas los ntawm kev thov voltage rau lawv.

Txuas lub zog hluav taws xob muaj hluav taws xob 220V hauv cov kab ke nrog kev tshawb xyuas qhov ntsuas ntawm lub tshuab hloov pauv thiab txuas cov hluav taws xob txuas mus rau lub network. Nrog rau multimeter teem rau AC voltage ntsuas, ntsuas ntsuas qhov voltage thoob lub transformer winding. Tom qab ntawd, tua lub hwjchim thiab tshuaj xyuas lwm cov cua. Sau cov txiaj ntsig koj tau ntawm daim ntawv. Thaum kuaj kab windings, yuav tsum ceev faj tsis txhob hloov windings thaum cov kev pabcuam tseem ceeb. Thaum ua ntawv thov voltage rau winding, tsis txhob kov cov lus kaw ntawm lwm cov windings, raws li cov xov hluav taws xob cuam tshuam rau lawv.

Ua ib qho tseem ceeb cable nrog lub fuse yas dhos, nruab 1A fuse.
Kauj ruam 5
Los ntawm cov ntaub ntawv ua tiav, nrhiav cov winding uas muaj qhov ntsuas hluav taws xob ntau tshaj. Txuas lub transformer nrog no winding rau lub network los ntawm kev sib txuas ntawm multimeter hauv series, hloov mus rau hom ntsuas tam sim no. Yog tias tsis muaj qhov thauj khoom tam sim no tsis pub dhau 30-50mA rau 200-300W qhov hloov pauv, nws muaj peev xwm pom tau tias thawj qhov ntsuas cua yog pom kom raug.
Kauj Ruam 6
Disconnect qhov mains supply, disconnect lub multimeter los ntawm kuaj winding, hloov mus rau voltage hom. Ntsuas qhov hluav taws xob qhov tseem ceeb thiab sau qhov txiaj ntsig tawm ntawm daim ntawv.
Kauj Ruam 7
Ntsuas qhov voltage hla cov ntsuas pom cathode windings. Yog tias ntawm qhov hluav taws xob tseem ceeb ntawm 220-225V nws yog 6, 25-6, 35V, tom qab ntawd cov kev tshawb xyuas winding yog thawj.
