Qee qhov loj hauv kev txhawj xeeb ntawm qhov hluav taws xob xa tawm kem
Yog tsis muaj kev tiv thaiv txhaum kev cai rau lub tshuab xau hluav taws xob thiab kev sib tsuam hluav taws xob nruab rau hauv lub thawv rau khoom. Thaum tus neeg tua hluav taws tawg, nws qhov teeb meem tsis zoo, tsis meej thiab tsis ua hauj lwm, lawv tseem zoo li qub, tab sis lawv tsis ua tus saib xyuas tiv thaiv thaum muaj kev tawm, luv luv thiab lwm yam xwm txheej.
Lub tshuab tua hluav taws thiab cov yas hluav taws xob hauv lub thawv tso tawm mus rau tus analog tiv thaiv. Lub precision ntawm kev tiv thaiv yog tsis siab, qhov yuam kev yog ntau tshaj 20%. Tus thawj 10A Circuit Court breaker, raws li qhov yuam kev ntawm + 20%, yuav tsum dhia thaum lub sij hawm tam sim no mus txog 12A, tab sis qhov kev kuaj ntawd, qee qhov teeb meem ntawm lub tog raj yuav tsis tawm thaum tam sim no yog 15A.
Tus neeg xiam oob qhab uas muab tso rau hauv lub thawv tso tawm yog tso loj heev, mus txog 30 mA, lossis txawm siab, tab sis qhov tsawg tshaj plaws tam sim no uas muaj kev xav tau los ntawm tib neeg yog, txiv neej laus: txog 1.1 mA, tus poj niam laus laus: txog 0.7 mA, tib neeg rhuav tshem ntawm lub siab tshaj plaws ntawm lub hwj chim tom qab hluav taws xob poob, tus txiv neej laus: muaj hnub nyoog li ntawm 16 mA, thiab txoj kev khiav qis tshaj txog 9 mA, tus poj niam laus: qhov nruab nrab yog kwv yees li 10.5 mA, thiab qhov tsawg tshaj tawm tso tawm tam sim no txog 9mA .
Kev tiv thaiv tus nqi ntawm cov hluav taws xob thiab lub ntsuas hluav taws xob ntsia lub thawv rau hauv lub voj voog, thiab tsis tuaj yeem hloov kho raws li qhov tseeb daim ntawv thov. Nws yuav ua rau muaj kev sib txawv hauv ntau qhov chaw, qee zaus nws yuav tsis mus txawv tebchaws.
Qhov kev tiv thaiv thiab kev sib tsuam ntawm qhov muag nyob rau hauv lub thawv tso tawm tsis muaj kev tiv thaiv tsis pub tshaj tawm. Thaum lub hwj huam hluav taws xob tsis txaus, qhov hluav taws xob muaj peev xwm ncav cuag 380V, 450V, thiab nws yuav hlawv tawm cov khoom siv hluav taws xob hauv tsev.
