Dab tsi yog cov laj thawj yog vim li cas pullamimeter tsuas yog qhia txog 107v thaum ntsuas a 220V voltage?
Thaum muaj xwm txheej no, lub zog yuav tsum tau txiav tawm kom meej rau cov laj thawj. Koj tuaj yeem ntsuas qhov voltage ntawm lwm tus neeg lub tsev kom pom tias nws yog dab tsi. Nquag, nws yuav tsum nyob ib ncig ntawm 200V rau 240V. Thaum lub sij hawm lub caij nyoog lub caij ntuj sov nyob rau hauv cov chaw nyob deb nroog, nws tuaj yeem poob rau ib ncig 160V. Qhov no yog vim lub zog hluav taws xob. Yog tias qhov ntsuas hluav taws xob ntsuas ntawm lwm tus neeg lub tsev yog ib txwm tab sis nws yog qhov txawv txav hauv koj lub tsev lossis rau ib qho ntawm lub voj voog, muaj ib qho txhaum, thiab lub hwj chim yuav tsum tsis txhob rov qab los txog thaum lub txhaum raug tshem tawm. Qhov no yog txhawm rau tiv thaiv cov xwm txheej xws li hluav taws thiab kev puas tsuaj rau cov khoom siv hluav taws xob. Tsom ntsoov rau kev soj ntsuam xyuas cov laj thawj xws li kev sib tiv thaiv hluav taws xob, thiab lwm yam ua rau muaj kev txhaum los ntawm kev ua txhaum thiab ua rau tib neeg thiab cov cuab yeej.
Firstly, nws yuav yog tias qhov nruab nrab ntawm cov hlau ntawm cov kab sab nraud tau tawg. Thib ob, koj tuaj yeem siv tus cwj mem hluav taws xob kev kuaj kom txiav txim los ntawm kev saib lub ci ci. Thib peb, lub roj teeb sab hauv ntawm multimeter tej zaum yuav tsis txaus, thiab koj tuaj yeem piv nws nrog lwm qhov sib txawv!
Ua ntej, yog qhov no uas tib qhov kev sib txuam zoo li thawj lub zog hluav taws xob ntawm tib lub qhov hluav taws xob ntawm lub b xwb- theem theem li 107v? Thib ob, yog nws zoo ib yam li kev ntsuas hluav taws xob ntawm thawj zaug {}}}} theem voltage nyob rau terminal kawg li 107v?
Yog tias tib qhov sib thooj ntsuas thawj lub ntsiab hluav taws xob ntawm ib qho hluav taws xob tseem ceeb li 220v, tab sis ntsuas qhov hluav taws xob tib yam li 107v; Tom qab ntawd yuav tsum muaj kev sib cuag tsis zoo vim muaj oxidation ntawm ob kab hluav taws xob ntawm lub voj voos (hloov mus)
Yog tias tib qhov sib thooj ntsuas thawj lub zog hluav taws xob ntawm ib lub zog ib qho li 220v, tab sis ntsuas lub davhlau ya nyob kawg li 107v; Tom qab ntawd nws yuav tsum yog tias txoj kab nrog kev ntsuas lub davhlau hluav taws xob kawg ntawm txoj kab yog ntau dua qhov muaj peev xwm ntawm kab xaim xaim, ua rau muaj peev xwm ntawm cov kab xaim hluav taws xob, ua rau muaj peev xwm ntawm kev poob qis.
Yog tias thawj zaug xaus voltages ntawm a thiab b tib -} theem theem ntawm tib lub zog yog ntsuas raws li 107v; Tom qab ntawd nws yuav tsum yog tias lub peev xwm ntawm kev faib tawm transformer hauv qhov chaw faib khoom muaj peev xwm ntawm cov neeg siv khoom muaj peev xwm ntawm cov neeg siv khoom muaj peev xwm ntev thiab cov kab uas muaj hluav taws xob ntev dhau, ua rau muaj hluav taws xob poob qis.
