Hloov hom fais fab mov hloov pauv kev hloov pauv
1. Txheeb xyuas cov kev tsis pom tseeb los ntawm kev pom cov tsos ntawm lub transformer. Whether the coil leads are broken, desoldered, whether there are burnt marks on the insulation material, whether the iron core fastening screws are loose, whether the silicon steel sheets are corroded, whether the winding coils are exposed, etc.
2. Rwb Thaiv Tsev Kuaj. Ntsuas cov txiaj ntsig tsis kam ntawm cov hlau core thiab thawj zaug, nruab nrab ntawm cov hlau thiab nruab nrab ntawm txhua qhov kev nyab xeeb, nruab nrab ntawm txhua qhov cua ntawm theem nrab uas siv tus multimeter r ultionation r ultionation r ultionation r ultion anch 10k. Lub pointer Meratus yuav tsum tag nrho cov taw tes rau infinity thiab nyob twj ywm nyob ruaj ruaj. Txwv tsis pub, nws qhia tau tsis zoo rwb rwb thaiv tsev kev ua tau zoo ntawm lub transformer.
3. Nrhiav tau ntawm coil txuas ntxiv. Tso qhov tso rau hauv r × 1 txoj haujlwm. Thaum kuaj, yog hais tias cov tsis kam nqi ntawm kev winding yog infinite, nws qhia tau tias cua hlob muaj qhov kev ua txhaum.
4. Txheeb xyuas qhov txawv ntawm Thawj Coils thiab theem theem nrab. Tus thawj thiab theem nrab Pins ntawm lub zog hloov hluav taws xob feem ntau coj tawm ntawm cov lus sib dhos, xws li 15v, 24v, thiab lwm yam. Txheeb xyuas cov cim no.
5. Nrhiav tau ntawm tsis muaj-thauj khoom tam sim no.
A, txoj kev ntsuas ncaj qha. Qhib tag nrho cov windings thib ob thiab tso cov puv hauv AC tam sim no hom (500ma). Txuas nws nyob rau hauv series nrog thawj winding. Thaum lub ntsaws ntawm thawj winding yog ntsaws rau hauv 220V ac main, pultimimeter qhia tsis muaj tus nqi tam sim no. Tus nqi no yuav tsum tsis txhob muaj ntau dua 10% rau 20% ntawm tag nrho cov kev thauj khoom tam sim no ntawm lub transformer. Qhov qub tsis muaj-thauj khoom tam sim no ntawm cov khoom siv hluav taws xob hluav taws xob hloov hluav taws xob yuav tsum yog ib puag ncig 100ma. Yog tias nws ntau dhau lawm, nws qhia tau tias lub transformer muaj kev ua txhaum luv luv.
B, Kev ntsuas ntsuas ntsuas Indirect. Txuas lub 10 Series nyob rau hauv thawj winding ntawm transformer / 5W reseformer / 5W reseformer / 5W resistor, tus thib ob yog tseem unloaded. Teeb lub multimeter rau gar voltage hom. Tom qab lub zog ntawm, siv ob txoj haujlwm los ntsuas qhov hluav taws xob tso tawm u thoob plaws Ohm txoj cai lij choj los laij tam sim no kuv, uas yog=u / r. F? Kev kuaj pom ntawm tsis muaj-load voltage. Txuas lub zog ntawm lub zog hloov pauv mus rau 220v Mains zog, thiab siv ntau txoj kev ntsuas qhov tsis muaj qhov tsis muaj cuab yeej (U21, U23, U23, U24) ntawm txhua lub tshuab winding. Qhov kev tso cai ua yuam kev feem ntau: Cov Hluav Taws Xob Loj Tshaj Plaws
6. Feem ntau, cov neeg hloov hluav taws xob tsawg siv hluav taws xob tso cai rau kev kub ntxhov ntawm 40 degree mus rau 50 degree. Yog tias cov ntaub ntawv rwb thaiv tsev siv yog qhov zoo, tau tso cai kub tau nce ntxiv.
7. Txheeb xyuas thiab paub qhov txawv ntawm tib lub npe ntawm txhua lub winding. Thaum siv lub zog hloov hluav taws xob, qee zaum ob lossis ntau dua cov windings ntxiv tuaj yeem txuas rau hauv cov koob kom tau txais cov volfage thib ob. Thaum siv lub zog hloov hluav taws xob hauv series, tib lub npe ntawm txhua qhov cua sib txuas yuav tsum txuas nrog kom raug thiab tsis ua yuam kev. Txwv tsis pub, cov transformer yuav tsis ua haujlwm zoo.
8. Kev tshawb pom thiab kev ntxub ntxaug ntawm cov kev sib pauv luv luv hauv hluav taws xob. Cov tsos mob tseem ceeb ntawm ib qho kev sib cav luv luv hauv lub zog transformer yog cov khoom siv cua sov thiab kev tawm tsam txawv txav ntawm cov kev winder. Feem ntau, tus inter ntau dua tig cov ntsiab lus luv luv hauv circuit Court hauv lub kauj, qhov ntau dua cov luv-Circuit Coin, thiab qhov hnyav dua transformer cov cua sov. Ib txoj kev yooj yim los tshawb nrhiav thiab txiav txim siab seb lub zog hloov hluav taws xob muaj qhov tsis muaj kev ua txhaum cai luv luv (cov txheej txheem ntsuas tau raug qhia ua ntej lawm). Transformers nrog luv luv-kab kev ua txhaum yuav tsis muaj-load tam sim no tseem ceeb tshaj 10% ntawm tag nrho cov khoom tam sim no. Thaum lub sijhawm luv ntawm Circuit Court yog loj heev, tus hloov pauv yuav ua kom sov li ntawm ob peb kaum lub zog ntawm, thiab kov cov hlau core nrog koj txhais tes yuav hnov kub. Txij ntawm no, nws tuaj yeem xaus lus tias muaj ib qho luv luv-circuit ci nyob rau hauv lub transformer tsis muaj ntsuas tsis muaj-thauj khoom tam sim no.
