Nraim kev nyab xeeb ntawm hluav taws xob faib lub thawv
Nws tsis muaj qhov txhaum tiv thaiv txheej txheem rau lub plhaub thaiv thiab tiv thaiv Circuit Court ntsia tau rau hauv lub thawv xa khoom. Thaum cov paim quav tiv thaiv, Circuit Court breaker nws tus kheej puas, txawv txav thiab ua haujlwm tsis zoo, lawv tseem saib zoo li qub, tab sis lawv tsis ua lub luag haujlwm tiv thaiv thaum muaj dej xau, luv Circuit Court thiab lwm yam xwm txheej.
Cov tiv thaiv to thiab tiv thaiv Circuit Court hauv lub thawv xa khoom muaj rau cov tiv thaiv analog. Qhov tseeb ntawm kev tiv thaiv tsis siab, qhov yuam kev ntau tshaj 20%. Lub tshuab hluav taws xob qub 10A Circuit Court, raws li qhov yuam kev ntawm + 20%, yuav tsum dhia thaum qhov tam sim no ncav cuag 12A, tab sis kev sim tiag tiag, qee qhov hluav taws xob hauv Circuit Court yuav tsis muaj kev tawm thaum qhov tam sim no yog 15A.
Cov tiv thaiv xau tso rau hauv lub thawv xa khoom yog ntsuas kom loj dua, txog 30 mA, lossis tseem siab dua, tab sis tam sim no tsawg tshaj plaws uas tuaj yeem hnov tau los ntawm cov neeg yog, cov txiv neej laus: txog 1.1 mA, poj niam laus: txog 0.7 mA, tib neeg tuaj yeem tau tshem ntawm qhov tam sim no ntawm lub zog tom qab hluav taws xob, tus txiv neej laus: qhov nruab nrab kwv yees li 16 mA, thiab qhov tsawg kawg khiav tawm tam sim no ntawm 9 mA, poj niam laus: qhov nruab nrab yog kwv yees li 10.5 mA, thiab qhov tsawg kawg yog tso tawm tam sim no yog txog 9mA Cov.
