6k ua AC Miniature Circuit Breaker yog dab tsi?
Lub tshuab hluav taws xob me me, feem ntau hu ua MCB, yog cov khoom siv tiv thaiv kev hloov pauv tsim los txiav tawm hluav taws xob hluav taws xob thaum muaj xwm txheej tsis zoo tshwm sim. Tsis zoo li ib txwm fuse, MCB ib txwm tuaj yeem rov pib dua tom qab qhov kev ua txhaum raug tshem tawm, ua kom yooj yim rau kev rov ua haujlwm thiab kev saib xyuas.
Lub sij hawm6k uayog hais txog lub breaker qhov ntsuas luv luv-circuit breaking peev nyob rau hauv cov kev xeem uas siv tau. Hauv cov ntsiab lus yooj yim, 6kA MCB yog tsim los cuam tshuam kev cuam tshuam rau lub neej yav tom ntej luv luv tam sim no txog 6,000 amperes thaum cov kev cai tau teev tseg.
Cov khoom lag luam ua raws li IEC / EN 60898-1 feem ntau qhia txog qhov tsis muaj xws li ntsuas tam sim no, ntsuas qhov ntsuas hluav taws xob, zaus, tawg peev xwm, thiab cov yam ntxwv cuam tshuam tam sim. Kev lag luam MCB ntau yam tuaj yeem muab 6kA kev ntsuas thoob plaws qhov sib txawv tam sim no thiab kev teeb tsa ncej.
6k ua tsis yog qhov ua haujlwm tam sim no ntawm lub breaker. Piv txwv li, A 16A MCB yog npaj los nqa nws cov ntsuas tam sim no raws li cov xwm txheej tau teev tseg, thaum daim duab 6kA piav qhia nws lub peev xwm cuam tshuam luv luv. Ob qhov kev qhia tshwj xeeb no teb cov lus nug txog engineering sib txawv kiag li.
Vim li cas 6kA tawg muaj peev xwm tseem ceeb?
Short circuits tuaj yeem tsim cov tam sim no siab heev hauv lub sijhawm luv luv. Yog tias cov cuab yeej tiv thaiv tsis tuaj yeem cuam tshuam qhov txhaum tam sim no muaj nyob rau ntawm nws qhov chaw teeb tsa, qhov tshwm sim tuaj yeem suav nrog kev puas tsuaj loj heev, kub dhau, khoom siv tsis ua haujlwm, lossis hluav taws xob txaus ntshai.
Yog li ntawd, lub peev xwm tawg yuav tsum tsis txhob xaiv tsuas yog vim 6kA yog ib qho kev qhia tshwj xeeb. Cov yav tom ntej luv luv-circuit tam sim no ntawm lub installation taw tes yuav tsum tau soj ntsuam, thiab xaiv breaker yuav tsum muaj peev xwm cuam tshuam txaus rau qhov system.
