Thaum tsim cov qauv hluav taws xob, cov hloov pauv nrog qhov tsis paub qee zaum siv. Hauv qhov no, nws yog qhov yuav tsum txiav txim siab qhov hloov pauv windings, lawv cov tswv yim thiab cov tawm hluav taws xob, cov naj npawb ntawm lem.

Cov Lus Qhia
Kauj ruam 1
Feem ntau cov feem ntau, thaum tsim cov qauv hluav taws xob hauv tsev, kauj ruam thiab theem kauj ruam hloov hluav taws xob yog siv. Lawv tsim qauv yog qhov yooj yim heev - lub tsho tiv thaiv nrog cov windings tau muab tso rau ntawm cov tub ntxhais ua los ntawm cov xov tooj hluav taws xob. Los ntawm kev hloov tus naj npawb ntawm lem hauv kev hloov theem ob, koj tuaj yeem tau txais qhov hluav taws xob uas sib txawv los ntawm qhov muab los mus rau thawj tus qauv winding.

Tus pib winding yog qhov winding uas qhov xaim hluav taws xob tau thov. Thib ob - qhov winding uas lub nra sib txuas. Thawj txoj kab hluav taws xob yog mob ua ntej, saum nws, dhau ntawm txheej txheej rwb thaiv tsev, theem nrab. Paub txog cov ntsiab cai no, koj yuav tsum ua tib zoo tshuaj xyuas lub tshuab hloov hluav taws xob thiab txiav txim siab cov davhlau ya nyob twg txuas rau sab nrauv winding xaim. Yog tias tsuas muaj ob txoj hlua windings thiab plaub qhov xaus ntawm lub tshuab hloov hluav taws xob, tom qab ntawd lub davhlau ya nyob twg yuav raug rau kev sib hloov ua lwm yam.

Koj tuaj yeem nrhiav lub davhlau ya nyob twg zaum ob ntawm kev sib hloov winding siv multimeter (tester). Txuas ib qho kev sojntsuam ntawm lub cuab yeej mus rau sab nraud lub davhlau ya nyob twg, nrog tus thib ob, sib chwv mus kov lwm feem peb kawg. Hauv ib kis, lub cuab yeej yuav tsum qhia lub xub ntiag ntawm Circuit Court, qhov no yuav yog qhov tawm thib ob ntawm kev sib hloov ntawm theem ob. Qhov ob seem txuas ntxiv yuav yog rau thawj.

Txheeb xyuas qhov pib ntawm lub siab thiab theem nrab windings, ntsuas lawv lub zog. Yog tias tus hloov hluav taws xob yog kauj ruam, qhov kev cuam tshuam ntawm kev sib hloov ntawm cov kab hluav taws xob theem ob yuav muaj ntau dua qhov ntawm lub hauv paus, qhov no yog vim muaj qhov nce ntxiv ntawm lem. Nrog cov kauj ruam nqes hluav taws xob, txoj haujlwm ua haujlwm qis yuav tsawg dua.
Kauj ruam 5
Qee qhov hloov pauv muaj ntau dua plaub tus. Qhov no txhais tau hais tias cov hluav taws xob nruab nrab txuas ntxiv raug tshem tawm ntawm kev sib hloov ntawm theem ob. Qhov pib (lub ntsiab) winding hauv qhov no yuav yog cua nrog ob tus neeg ua. Rau theem hloov mus los, cov taub ntawm cov hlau tuaj yeem pab txiav txim siab qhov kev sib hloov theem ob - nws yog thicker tshaj ntawm thawj. Qhov no yog vim qhov tseeb tias thaum lub zog hluav taws xob tsawg, lub zog tam sim no nce.
Kauj Ruam 6
Txhawm rau txiav txim siab tus naj npawb ntawm lem ntawm windings, cua ntxiv ib qho nrog paub cov xov tooj ntawm cov lem ntawm qhov kev hloov theem ob - piv txwv li, tej zaum yuav muaj 50. Tom qab ntawd thov siv qhov voltage me (9-12 V) mus rau lub thawj winding. Ntsuas qhov ntsuas ntawm qhov tawg ntawm theem nrab thiab ntu kev tiv thaiv. Tus naj npawb ntawm lem yog suav raws li tus qauv: n = Un × Wadd / Uadd. Ntawm no n yog tus naj npawb ntawm lem ntawm lub hloov pauv winding, Un yog qhov voltage ua raws ntawm no winding, Wadd yog tus naj npawb ntawm lem hauv lub winding ntxiv, thiab Uadd yog qhov voltage thoob nws.
