Koj puas tuaj yeem ntsuas qhov zoo ntawm lub cev muaj zog nrog multimeter?
Qhov no multimeter tuaj yeem ntsuas AC voltage, DC voltage, AC tam sim no, DC tam sim no, tsis kam thiab capacitance, buzzer iav, diode, thiab lwm yam., thiab nws kuj muaj kev txawj ntse tiv thaiv kev kub hnyiab tsim, tsis siv neeg kaw, thiab lwm yam. function yog heev haib. Rau ib tug zoo tib yam electrician, nws yog kiag li txaus. Cov kev txwv tshwj xeeb yog tag nrho ntawm lub rooj, yog li kuv yuav tsis mus rau hauv cov ntsiab lus.
Yog li koj tuaj yeem ntsuas qhov zoo ntawm lub cev muaj zog nrog multimeter? Yuav ntsuas nws li cas?
Kuv xav tias qhov no yuav tsum tau saib los ntawm ob yam. Yog tias nws yog luv luv ntawm cov coils, tig-rau-tig luv luv Circuit Court thiab qhib Circuit Court, cov no tuaj yeem ntsuas los ntawm multimeter. Yog hais tias nws yog ib tug luv luv Circuit Court rau hauv av thiab to hauv av, lub rwb thaiv tsev tiv thaiv tus nqi nyob rau hauv no hwm yuav tsum yog megohmmeter ( rwb thaiv tsev ntsuas ntsuas, co rooj).
Luv luv, siv multimeter los ntsuas qhov luv luv ntawm lub cev muaj zog coils thiab luv Circuit Court thiab qhib Circuit Court ntawm coil tig.
Muaj cov motors loj thiab me, tab sis tag nrho peb-theem motors yog tsim los ntawm peb windings. Nws yog ib qho tsim nyog los ntsuas qhov tsis kam ntawm peb-theem winding los txiav txim seb lub cev muaj zog puas yog. Qhov tsis kam ntawm peb-theem winding nws txawv raws li lub zog ntawm lub cev muaj zog, tab sis lawv cov kev tiv thaiv tsis txawv heev, feem ntau ntawm 2 thiab 5 ohms.
Feem ntau, peb-theem motors muaj rau lub davhlau ya nyob twg, tab sis rau qee lub tshuab hluav taws xob qis, cov tuam ntxhab tau tsim lub hnub qub zoo li lossis lub kaum sab xis lub cev muaj zog, thiab tsuas muaj peb lub terminals hauv lub thawv sib txuas. Txoj kev tshawb nrhiav ntawm lub cev muaj zog yog tib yam li ntawm rau lub terminals, tshwj tsis yog tias lub kauj voj voog yog luv luv, yog li peb cov kws tshaj lij hluav taws xob tsis tuaj yeem ntes nws.
Ua ntej ntsuas, peb yuav tsum xub txiav lub hwj huam mov thiab tshem tawm cov khoom sib txuas. Xav tias peb kab saum toj kawg nkaus yog lub taub hau kawg thiab peb kab hauv qab yog tus Tsov tus tw kawg. Cov ntawv sau thaum pib thiab xaus qhia tias kev ntaus ntawv tsis yooj yim, yog li kuv tau hu thawj qhov kawg li 1, 3, 5, thiab kawg kawg li 2, 4, 6.
Vim tias peb tsis paub qhov kev tiv thaiv ntawm peb-theem windings, peb thawj zaug ntaus lub multimeter mus rau qee yam iav ntawm cov hluav taws xob thaiv, thiab thaum kawg pom cov iav tsim nyog, thiab tom qab ntawd ua qhov sib piv kom raug.
Tom qab nrhiav tau ib lub iav tsim nyog, ntsuas qhov kev tiv thaiv qhov tseem ceeb ntawm peb-theem windings ntawm thawj kawg feem. Yog hais tias qhov kev tiv thaiv qhov tseem ceeb ntawm peb-theem windings tsis ntau sib txawv thiab nyob rau hauv ib tug tsim nyog ntau yam, peb xav tias qhov tseem ceeb ntawm qhov kev tiv thaiv ntawm peb-theem windings yog ib txwm. Kuv yeej tsis ntseeg koj. Peb tuaj yeem ntsuas lwm qhov kawg thiab ua qhov sib piv, kom paub tseeb.
Cov teeb meem ntawm peb-theem windings yog qhov yooj yim los daws. Nws yog ib qho teeb meem los txiav txim siab tig-rau-tig qhov txhaum ntawm lub kauj.
Cia peb tham txog tig-rau-tig luv luv ua ntej. Qhov tshwm sim ntawm tig-rau-tig luv luv Circuit Court yog tias lub cev muaj zog hauv zos rhuab thiab peb-theem tam sim no tsis sib npaug. Ntsuas nrog lub clamp meter, qhov ncaj qha tam sim no ntawm luv luv Circuit Court yog qhov loj dua. Siv lub multimeter los ntsuas qhov tsis kam ntawm lub taub hau thiab tus Tsov tus tw kawg ntawm peb-theem kauj, thiab lub luv luv-circuited theem yog me dua.
Yog tias lub voj voog tig-rau-tig qhib, qhov kev tawm tsam ntawm qhov pib thiab qhov kawg ntawm lub coil winding yuav tsum tsis muaj kawg lossis loj heev.
Yog hais tias lub kauj yog luv luv rau hauv av los yog xau hluav taws xob, koj yuav tsum siv megohmmeter. Vim tias qhov voltage theem ntawm lub multimeter tsawg dhau, nws tsis tuaj yeem ntsuas cov ntaub ntawv raug.
Txhawm rau ntsuas cov khoom siv hluav taws xob tsawg lossis kab, peb tuaj yeem xaiv 500 megger.
Megohmmeter tseem hu ua co rooj vim nws yog lub tshuab hluav taws xob DC tes.
Megohmmeter, tseem hu ua rwb thaiv tsev ntsuas ntsuas, tshwj xeeb yog siv los ntsuas kev tiv thaiv hluav taws xob siab tshaj megohmmeter qib.
Feem ntau, cov txheej txheem kev lag luam yog qhov rwb thaiv tsev tiv thaiv hauv av yog siab tshaj 0.5 megohm, uas yog ib txwm muaj.
Kev ua haujlwm yog yooj yim heev. Peb tsuas tuaj yeem ntsuas qhov ntsuas ntsuas qhov ntsuas hluav taws xob tom qab nws tau leveled thiab stabilized thiab kho.
Txuas lub L davhlau ya nyob twg ntawm megohmmeter mus rau lub cev muaj zog winding, thiab txuas lub E davhlau ya nyob twg mus rau lub cev muaj zog vaj tse, thiab ntsuas qhov tsis kam ntawm rau lub cev muaj zog terminals rau lub cev muaj zog vaj tse. Lub rwb thaiv tsev tsis zoo yog qhov qub yog tias nws ntau dua lossis sib npaug ntawm {{0}}}.5 megohmmeter, thiab nws raug suav tias yog qhov xau yog tias nws tsawg dua 0.5 megohmmeter, thiab nws yog luv luv yog tias qhov kev tiv thaiv yog heev. me me.
Qee cov phooj ywg xav tias megohmmeter tuaj yeem siv los ntsuas qhov rwb thaiv tsev ntawm lub cev muaj zog lossis tig-rau-tig. Tus kheej, kuv xav tias nws yog qhov tsis tsim nyog, vim hais tias qhov voltage ntawm megohmmeter siab tshaj qhov tiv taus voltage theem ntawm kauj, uas yuav ua rau lub rwb thaiv tsev ntawm coil.
Kev ntsuas ntawm ib-theem lub cev muaj zog kuj siv cov txheej txheem saum toj no. Lub hom phiaj tseem yog los txiav txim seb puas muaj qhov txhaum ntawm cov coils, seb puas muaj qhov qhib Circuit Court thiab luv Circuit Court hauv coils, thiab seb puas muaj luv Circuit Court thiab to hauv av.
