Dab tsi yog Overload? Dab tsi yog Overcurrent? Koj puas paub ~
Kev tiv thaiv overcurrent:
Peb tau hais ua ntej tias overcurrent yog lub xeev. Thaum overcurrent tshwm sim, nws feem ntau me dua li qhov luv-circuit tam sim no, thiab nws yog nyob rau hauv rau lub sij hawm.
Feem ntau, nyob rau hauv hluav taws xob circuits, qhov tshwm sim ntawm luv luv Circuit Court yog ntau me dua li ntawm overcurrent, tshwj xeeb tshaj yog thaum lub cev muaj zog yog nquag pib thiab thim rov qab.
Dab tsi yuav tsum tau hais ntawm no yog tias thaum muaj qhov overcurrent hauv kab, yog tias tus nqi tam sim no tuaj yeem rov qab mus rau qhov qub ua ntej mus txog qhov kub siab tshaj plaws, ces cov khoom siv hluav taws xob tseem tuaj yeem ua haujlwm ib txwm.
Tab sis muaj ib lub ntsiab lus, qhov overcurrent ntawm no yuav ua rau lub inrush tam sim no puas lub cev muaj zog. Lub sijhawm no, lub zog hluav taws xob tam sim no yuav ua rau cov khoom siv hluav taws xob puas tsuaj. Yog li ntawd, nws yog ib qho tsim nyog yuav tau txiav tawm lub hwj huam mov hauv lub sijhawm.
Kev tiv thaiv overcurrent siv ib qho kev tiv thaiv overcurrent relay, uas yog ntsia rau hauv kev tiv thaiv Circuit Court. Thaum qhov tam sim no ncav cuag tus nqi, tus relay yuav ua. Nws ib txwm kaw kev sib cuag yog txuas nrog nyob rau hauv series nyob rau hauv cov ceg uas lub contactor coil nyob rau hauv thiaj li hais tias lub contactor kauj yog powered tawm, thiab ces lub ntsiab kev sib cuag ntawm tus contactor nyob rau hauv lub ntsiab Circuit Court yog disconnected, thiaj li hais tias lub cev muaj zog lub cev muaj zog raug txiav tawm nyob rau hauv lub cev. sij hawm.
Kev tiv thaiv luv luv:
Ntau tus novices tsis paub tias nyob rau hauv lub hwj chim system yog hais tias cov khoom siv hluav taws xob nyob rau hauv txoj kab los yog lub rwb thaiv tsev ntawm nws cov xov hlau puas, tej zaum yuav muaj teeb meem tsis ua hauj lwm los yog loads luv luv circuits. Tom qab ntawd, thaum muaj qhov xwm txheej zoo li no tshwm sim, cov khoom siv yuav muaj qhov tsis ua haujlwm luv luv.
Thaum lub sij hawm luv luv-circuit txhaum tshwm sim, lub sijhawm no, tam sim no tam sim no ntawm cov khoom siv tsis yog tsuas yog me ntsis siab tshaj qhov ntsuas tam sim no tab sis ntau dua kaum ob zaug.
Qhov tshwm sim ntawm qhov no yuav yog tias cov khoom siv hluav taws xob puas tsuaj vim yog lub zog hluav taws xob muaj zog hauv cov kab hluav taws xob, thiab ib qho arc tsim nyob rau tib lub sijhawm, thiab qhov tshwm sim loj yuav ua rau muaj hluav taws kub.
Yog li ntawd, peb yuav tsum tau ua qee yam kev ntsuas kom tsis txhob muaj kev puas tsuaj los ntawm kev ua haujlwm luv luv, uas yog hu ua kev tiv thaiv luv luv. Ntawm no peb yuav tsum tau txiav tawm sai sai tom qab muaj kev txhaum tshwm sim. Cov txheej txheem feem ntau siv ntawm no yog txhawm rau nruab ib lub fuse lossis qhov hluav taws xob qis hluav taws xob hauv hluav taws xob hluav taws xob.
