Yog vim li cas ib tug multimeter nyeem tsuas yog 107V thaum lub voltage nyeem ntawv yog 220V?
Hauv qhov no, lub hwj chim yuav tsum raug txiav tawm los tshawb xyuas qhov laj thawj. Koj tuaj yeem sim nws ntawm lwm tus neeg lub tsev kom pom tias nws zoo li qub. Feem ntau nws yuav tsum nyob ib ncig ntawm 200 volts rau 240 volts. Tus nqi siab tshaj plaws thaum lub caij ntuj sov irrigation nyob rau hauv cov cheeb tsam nyob deb nroog yuav tsawg li 160 volts. Qhov no yog vim lub hwj chim mov system. Yog tias lwm tus neeg lub tsev nyob ib txwm muaj, tab sis ib tus kheej lub tsev lossis ib qho ntawm cov channel yog qhov txawv txav, ces muaj qhov txhaum thiab nws yuav tsum tau kho ua ntej lub hwj chim muab. Txhawm rau tiv thaiv kev puas tsuaj hluav taws thiab hluav taws xob. Tsom ntsoov rau kev txheeb xyuas kom meej seb puas muaj kev sib cuag tsis zoo, hluav taws xob tsis raug, hluav taws xob hnyav ntawm cov xov hlau uas nyias nyias thiab dhau, thiab lwm yam. Nws yog qhov zoo tshaj plaws los nug ib tus kws kho hluav taws xob los pab daws teeb meem. Txhawm rau tiv thaiv kev ua haujlwm tsis zoo ntawm kev ua kom puas tsuaj rau tib neeg thiab khoom.
Ua ntej, cov kab sab nraud tuaj yeem tawg vim yog cov kab nruab nrab. Qhov thib ob, koj tuaj yeem siv tus cwj mem hluav taws xob los ntsuas qhov kaj thiab qhov tsaus ntuj los txiav txim. Lub roj teeb sab hauv ntawm peb lub multimeter tsis txaus. Siv lwm multimeter rau kev sib piv!
Ua ntej tshaj plaws, nws puas tuaj yeem siv tib lub ntsuas hluav taws xob los ntsuas qhov pib voltage ntawm ib-theem kab A ntawm tib lub zog loj rau 220V, tab sis ntsuas qhov pib hluav taws xob ntawm ib-theem kab B yuav yog 107V? Qhov thib ob lo lus nug yog seb qhov voltage ntsuas nrog tib lub multimeter thaum pib ntawm ib theem kab A yog 220V, thiab qhov voltage ntsuas ntawm nws qhov kawg yog 107V?
Yog hais tias tib lub multimeter yog siv los ntsuas qhov pib voltage ntawm ib-theem kab A ntawm tib lub zog loj, qhov ntsuas pib qhov hluav taws xob yog 220V, thiab qhov ntsuas hluav taws xob ntawm ib theem kab B yog 107V; Tom qab ntawd lub sab sauv thiab qis kawg ntawm lub Circuit Court breaker (hloov) ntawm ib-theem kab B yog raws li ob lub ntsiab lus xaim yuav tsum muaj kev sib cuag tsis zoo vim yog oxidation, ua rau muaj kev tiv thaiv kev tiv thaiv thiab kev poob qis.
Yog hais tias tib lub multimeter yog siv los ntsuas ib-theem kab A los yog ib-theem kab B nrog tib lub hwj huam mov, thiab qhov ntsuas pib kawg voltage yog 220V, thiab ntsuas qhov kawg voltage yog 107V, ces nws yuav tsum yog cov kab nrog. qhov ntsuas qhov kawg voltage ntawm 107V ntev dhau los lossis cov kab ntawm kab ntev dhau lawm. Lub load tam sim no ntau dua qhov kev nyab xeeb nqa lub peev xwm ntawm cov kab hluav taws xob, ua rau muaj qhov poob qis.
Yog tias qhov ntsuas hluav taws xob ntsuas thaum pib ntawm ib theem kab A thiab B ntawm tib lub zog hluav taws xob yog 107V, ces nws yuav tsum yog tias lub peev xwm ntawm cov khoom siv hluav taws xob faib hluav taws xob hauv qhov chaw nres tsheb hluav taws xob tsawg tsawg dua qhov siv hluav taws xob tsawg. muaj peev xwm ntawm cov neeg siv, los yog hais tias lub tis transformer Cov kab xa tawm los ntawm tus neeg siv yog ntev dhau lawm thiab muaj tsawg dhau voltage poob.
