Txoj kev nkhaus ntawm Circuit Court breaker

Keeb kwm ntawm txoj kev nkhaus

Lub tswv yim ntawm txoj kev nkhaus tau pib hauv IEC ntiaj teb thiab siv los faib cov micro-circuit breakers (B, C, D, K thiab Z) los ntawm IEC cov qauv.Tus txheej txheem txhais cov kev txwv qis dua thiab sab sauv rau kev mus ncig, tab sis cov tuam txhab tsim khoom muaj qhov yooj yim los txiav txim siab cov ntsiab lus meej hauv cov qauv no uas yuav ua rau lawv cov khoom mus ncig.Daim duab kos duab qhia txog qhov kam rau ua qhov chaw uas cov chaw tsim khoom tuaj yeem teeb tsa cov ntsiab lus mus txawv tebchaws ntawm nws lub Circuit Court breaker.

Txoj kev nkhaus ntawm Circuit Court breaker

Cov yam ntxwv thiab kev siv ntawm txhua qhov nkhaus, los ntawm feem ntau rhiab heev mus rau yam tsawg rhiab, yog:

Z: Mus ncig ntawm 2 mus rau 3 npaug ntawm qhov ntsuas tam sim no, tsim nyog rau kev siv cov khoom siv hluav taws xob zoo xws li cov khoom siv semiconductor

B: Taug kev ntawm 3 mus rau 5 zaug ntsuas tam sim no

C: Mus ncig ntawm 5 mus rau 10 npaug ntawm qhov ntsuas tam sim no, haum rau nruab nrab inrush tam sim no

K: Kev mus ncig ntawm 10 mus rau 14 npaug ntawm qhov ntsuas tam sim no, haum rau cov khoom siv nrog cov khoom siv hluav taws xob siab, feem ntau yog siv rau cov motors thiab transformers

D: Mus ncig ntawm 10 mus rau 20 npaug ntawm qhov ntsuas tam sim no, haum rau siab pib tam sim no

Kev tshuaj xyuas "Kev Sib piv ntawm tag nrho IEC Trip curves", koj tuaj yeem pom tias cov dej ntws siab dua ua rau muaj kev mus ncig sai dua.

Lub peev xwm los tiv thaiv impulse tam sim no yog ib qho tseem ceeb rau kev xaiv ntawm txoj kev nkhaus.Qee qhov loads, tshwj xeeb tshaj yog cov motors thiab transformers, muaj kev hloov pauv nyob rau hauv tam sim no, hu ua impulse tam sim no, thaum cov neeg raug kaw.Cov cuab yeej tiv thaiv sai dua, xws li b-trip curves, yuav paub txog qhov kev nkag mus no ua tsis tiav thiab tig rau hauv Circuit Court.Rau cov hom kev thauj khoom no, kev mus ncig ua si nrog cov ntsiab lus sib nqus siab (D lossis K) tuaj yeem "dhau" los ntawm kev nkag mus tam sim no, tiv thaiv Circuit Court los ntawm kev mus ncig tsis raug.
