Txoj kev tsim kom zoo tshaj plaws yog nyob ntawm hom kev cuam tshuam ntawm Circuit Court breaker thiab kev tswj fais fab mov tej yam kev mob: Rau cov xwm txheej nrog ib tug DC kev khiav hauj lwm mechanism thiab qhov twg lub twj tso kua mis yuav phim lub voltage, sab hauv triggering yog qhov yooj yim tshaj rau kev khiav hauj lwm thiab muaj kev tswj kom meej tshaj plaws, ua rau nws nyiam kev xaiv; Yog tias siv AC lub zog, lub tshuab hlau nplaum tas mus li, lossis ib qho kev tswj xyuas tag nrho, yuav tsum tau siv cov khoom siv sab nraud; manual triggering yog tsim rau tshwj xeeb commissioning los yog teeb meem scenarios yam tsis muaj hluav taws xob tswj mechanism.
Internal Triggering: Qhov Kev Xaiv Zoo Tshaj Plaws Hauv Cov Txheej Txheem Kev Ua Haujlwm
Cov xwm txheej siv tau: Lub Circuit Court breaker muaj DC electromagnetic los yog lub caij nplooj ntoos hlav kev khiav hauj lwm mechanism, thiab lub twj tso kua mis tso zis voltage (xws li, DC 220V) phim lub coil qhov ntsuas voltage.
Qhov zoo: Cov cuab yeej muab kev sib koom ua ke tswj fais fab tso zis thiab teeb liab tau txais, ua kom lub sijhawm meej thiab cov ntaub ntawv siab sib xws; Kev xaim yog qhov yooj yim, tsuas yog xav tau kev sib txuas ntawm cov kab tswj hwm mus rau "internal triggering" chaw nres nkoj, tshem tawm qhov xav tau rau kev ua haujlwm sab nraud.
Kev ceev faj: Tus thawj tswj fais fab mov fuse nyob rau hauv lub txee tswj yuav tsum tau muab tshem tawm los tiv thaiv luv luv circuits los yog cov khoom puas tsuaj los ntawm parallel ua hauj lwm ntawm cov khoom siv hluav taws xob sab hauv thiab sab nraud; Tsis haum rau AC kaw coils lossis scenarios nrog voltage mismatch.
Cov xwm txheej pom zoo: Kev soj ntsuam kev tiv thaiv niaj hnub, kev tshuaj xyuas lub Hoobkas, kev saib xyuas hauv nruab nrab ntawm lub chaw nres tsheb, thiab lwm qhov chaw tswj tau.
Sab Nraud Trigger: Ib Txoj Kev Hloov Kho Kom Yooj Yim rau Cov Chaw Ua Si
Cov xwm txheej siv tau: Siv cov khoom siv hluav taws xob ua haujlwm AC, cov khoom siv hluav taws xob ruaj khov, lossis cov xwm txheej uas nyob ntawm - tsis tso cai rau kev nkag mus rau qhov ntsuas qhov ntsuas hluav taws xob.
Qhov zoo: Ua tiav ntawm - qhov chaw fais fab mov, muaj zog sib raug zoo, zam cov teeb meem ntsig txog cov cuab yeej tso tawm tsis txaus; Yuav siv tau nrog oscilloscope hom kom tau cov coil tam sim no waveforms rau kev soj ntsuam tob - zaum faults xws li mechanism jamming thiab txawv txav core txav.
Teeb Cov Ntsiab Lus: Txuas cov kab "External Trigger" nyob rau hauv parallel hla lub kaw / qhib coil. Cov cuab yeej siv lub sij hawm lub kauj yog energized raws li lub sij hawm pib taw tes; Txhawb AC / DC 10-300V dav qhov hluav taws xob tau txais, yoog raws li qhov xav tau ntawm kev sib xyaw AC / DC fais fab sib txuas.
