Huab cua hloov (tom qab no hu ua "air hloov", ntawm no peb tshwj xeeb xa mus rau GB10963.1 tus qauv hauv tsev hluav taws xob hluav taws xob) kev tiv thaiv khoom siv yog cable, cov lus nug tseem ceeb yog "vim li cas yuav tsum tau hloov pauv huab cua tiv thaiv overload tiv thaiv thiab tiv thaiv luv luv" tuaj yeem txuas ntxiv mus rau "vim li cas yuav tsum tau teeb tsa kev tiv thaiv overload thiab tiv thaiv luv luv tib lub sijhawm"
1.Dab tsi yog overcurrent?
Lub voj tam sim no uas ntau dua qhov ntsuas nqa tam sim no ntawm lub voj voog tus neeg xyuas pib yog overcurrent, suav nrog overload tam sim no thiab luv-circuit tam sim no.
2. lub cable overload tiv thaiv
Cov hluav taws xob hluav taws xob vim yog cov khoom siv hluav taws xob ntau dhau los yog cov khoom siv hluav taws xob nws tus kheej overload (xws li lub cev muaj zog ntawm lub tshuab hluav taws xob loj dhau) thiab lwm yam vim li cas, tus nqi tam sim no yog ntau zaus ntawm qhov ntsuas tam sim no ntawm Circuit Court, qhov tshwm sim yog tias cable khiav hauj lwm kub siab tshaj. tus nqi tso cai, cov kab hluav taws xob rwb thaiv tsev nrawm nrawm, ua rau lub neej luv.Piv txwv li, rau PVC cables, qhov siab tshaj plaws tso cai ua hauj lwm kub rau ib ntev lub sij hawm yog 70 ° C, thiab qhov tso cai nyob rau hauv lub sij hawm luv luv Circuit Court tsis tshaj 160 ° C.
Lub cable tuaj yeem tiv taus qee qhov overload tam sim no rau qee lub sijhawm, tab sis lub sijhawm yuav tsum raug txwv.Yog hais tias lub overload tam sim no ntev dhau lawm, lub rwb thaiv tsev cable yuav puas, uas tej zaum yuav ua rau luv luv Circuit Court txhaum.Kub lub xeev ntawm rwb thaiv tsev txheej ntawm lub cable nyob rau hauv ib txwm tam sim no, overload tam sim no, thiab luv luv Circuit Court tam sim no.
Yog li ntawd, nyob rau hauv tus qauv tus nqi ntawm cov khoom Circuit Court breaker, lub Circuit Court breaker yuav tsum yog 1.13In, lub overload tam sim no tsis ua hauj lwm nyob rau hauv 1 teev (In≤63A}), thiab thaum tam sim no qhib ntawm 1.45In, lub overload. kab yuav tsum tau muab tshem tawm hauv 1 teev.Overload tam sim no tso cai rau txuas ntxiv rau 1 teev los coj mus rau hauv tus account qhov txuas ntxiv ntawm cov khoom siv hluav taws xob thiab lub cable nws tus kheej muaj peev xwm dhau, tsis tuaj yeem ua rau me ntsis overloaded kab, Circuit Court breaker yuav txiav tawm lub hwj chim, uas yuav cuam tshuam rau qhov qub. ntau lawm thiab lub neej ntawm cov neeg nyob.
Cov khoom tiv thaiv ntawm Circuit Court breaker yog cable.Nyob rau hauv cov xwm txheej overload, lub sij hawm ntev overload yuav ua rau qhov kub thiab txias, uas ua rau muaj kev puas tsuaj rau lub rwb thaiv tsev txheej ntawm lub cable, thiab nws thiaj li yog ib tug luv luv Circuit Court txhaum.
Nyob rau hauv luv luv Circuit Court tej yam kev mob, qhov kub yuav nce nyob rau hauv ib tug luv luv lub sij hawm, yog hais tias tsis txiav nyob rau hauv lub sij hawm, nws yuav ua rau spontaneous combustion ntawm lub rwb thaiv tsev txheej, yog li raws li ib tug tiv thaiv tivthaiv ntawm lub Circuit Court breaker, ob qho tib si overload tiv thaiv muaj nuj nqi, tab sis kuj yuav tsum tau luv luv. Circuit Court tiv thaiv muaj nuj nqi.
