Kev xa xov hluav taws xob yog ib qho khoom siv kho tshuab thiab vim li ntawd yuav hnav thiab kua muag. Ua ntej nruab nws nyob rau hauv Circuit Court, nws yuav tsum tau kuaj xyuas. Txhawm rau ua txoj haujlwm no, cov khoom siv tau rau txhua tus tswv tsev yog siv.
Cov Lus Qhia
Kauj ruam 1
Txheeb xyuas cov relay pinout. Thawj zaug ntawm txhua qhov, nrhiav kom pom qhov twg winding ua. Kuj pom qhov chaw nyob ntawm cov ntsiab lus ntawm cov neeg sib txuas lus: ib txwm qhib (uas kaw thaum txhais) thiab ib txwm kaw (uas qhib thaum txhais). Yog tias cov ntawv qhia txuas ntxiv yog lus Askiv, cov kab lus "nquag qhib" txhais tau tias feem ntau qhib kev sib cuag, "nquag kaw" txhais tau tias feem ntau kaw. Cov sib pauv hloov pauv hu tau tuaj yeem sawv cev hauv daim ntawv ntawm ob pawg, ib tus ntawm ib txwm qhib thiab lwm qhov ib txwm kaw, thiab cov uas tau sib xyaw ntawm ib qho ntawm cov chaw nyob hauv ib txoj hauv kev uas lawv tus lej tag nrho raug txo los ntawm plaub mus rau peb.
Kauj ruam 2
Yog hais tias lub txeej voltage ntawm lub relay tsis paub, tab sis tsuas yog cov txeej tam sim no paub, ntsuas qhov coil tsis kam. Tom qab ntawd khoo qhov ntsuas ntsuas los ntawm lub txeej tam sim no (ua ntej hloov ob tus nqi rau SI units), thiab koj tau txais qhov ntsuas hluav taws xob hauv qhov ntev. Qhov kev sim no tsis siv rau kev xa rov qab nrog AC windings.
Kauj ruam 3
Yog tias, hauv chav ua haujlwm dhau los, koj ntsuas qhov tsis kam ntawm lub kauj vuam rov qab, koj tib lub sij hawm pom tias qhov cua tau zoo. Yog tias koj tsis tau ntsuas qhov ntsuas no, siv nws. Thaum ntsuas, tsis txhob kov cov khoom ntawm qhov winding thiab qhov sim ntawm ohmmeter, thiaj li tsis tau txais qhov poob siab los ntawm tus kheej-induction voltage.
Kauj ruam 4
Thov tsuas siv AC voltage rau AC winding. Tsis txhob cia nws nrog diode.
Kauj ruam 5
Sim ua ntawv thov DC voltage rau winding sib npaug zos ua hauj lwm voltage. Yog tias cov kev xa mus rau qhov zoo, nws yuav mus ncig. Tsis tas li, tsis txhob kov cov winding coj thiab qhov chaw sau cov laj thawj rau tib lub laj thawj. Nws yog qhov tsim nyog los cuam tshuam lub kauj nrog 1N4007 diode, txuas nrog hauv thim rov qab polarity, tab sis koj yuav tsum tsis txhob rov qab qhov polarity ntawm qhov winding kom tsis txhob mus luv Circuit Court. Nws yog tsis yooj yim sua los kov cov kab hluav taws xob tam sim no nyob rau hauv lub xub ntiag ntawm diode txhua lub sijhawm, vim nws tuaj yeem swb thaum twg los tau.
Kauj Ruam 6
Siv ib qho ohmmeter, kuaj xyuas qhov xwm txheej ntawm txhua pawg neeg tiv tauj. Thaum tsis muaj voltage rau ntawm qhov winding, ib txwm qhib pawg yuav tsum qhib, ib txwm muaj pawg yuav tsum raug kaw. Thaum qhov voltage tawm, qhov teeb meem no yuav tsum tau rov qab.
