1. Dab tsi yog ib qhoArc Fault Tiv Thaiv Circuit Breaker(AFDD)?
Vim yog qhov tsis zoo ntawm kev sib cuag lossis kev puas tsuaj ntawm cov rwb thaiv tsev, "bad arc" nrog lub zog siab thiab kub siab yog tsim tawm hauv lub voj voog hluav taws xob, uas tsis yooj yim nrhiav tau tab sis yooj yim ua rau cov khoom siv puas tsuaj thiab txawm tias hluav taws.
Qhov xwm txheej uas muaj feem yuav muaj cov arcs tsis zoo
Qhov Fault arc, feem ntau hu ua hluav taws xob spark, qhov kub hauv nruab nrab siab heev, cov hlau spatter tshwm sim, yooj yim ua rau muaj hluav taws. Thaum parallel arc tshwm sim, cov xov hlau thiab cov xov hlau nruab nrab tsis sib cuag ncaj qha, tsuas yog vim tias daim tawv nqaij rwb thaiv tsev laus poob cov yam ntxwv rwb thaiv tsev lossis daim tawv nqaij rwb thaiv tsev puas tsuaj, tab sis qhov deb ntawm cov xov hlau thiab kab nruab nrab yog ze heev, thiab tam sim no rhuav tshem cov huab cua ntawm cov xov hlau thiab kab nruab nrab, thiab cov hluav taws xob raug tso tawm ntawm cov xov hlau thiab kab nruab nrab.
2. Cov yam ntxwv ntawm cov teeb meem qis-voltage arc:
1. Lub waveform tam sim no muaj ntau lub suab nrov siab
2. Muaj qhov poob qis ntawm qhov txhaum arc
3. qhov ceev nce tam sim no feem ntau loj dua li lub xeev ib txwm muaj
4. Txhua ib nrab lub voj voog muaj ib cheeb tsam uas tam sim no ze rau xoom, uas hu ua "cheeb tsam xoom tam sim no".
5. Lub zog hluav taws xob waveform ze rau lub duab plaub fab, thiab qhov hloov pauv hauv thaj chaw xoom tam sim no loj dua li lwm lub sijhawm, thiab qhov siab tshaj plaws yog thaum tam sim no tshaj xoom
6. qhov txhaum arc feem ntau yog sporadic, intermittent
7. Lub waveform tam sim no muaj zog randomness
Kev tiv thaiv thiab tswj hluav taws xob, uas yog thawj qhov teeb meem hluav taws, tab tom tseem ceeb zuj zus.Arc Fault Circuit Breaker (AFDD), ib lub qhov hloov hluav taws xob tiv thaiv arc uas tiv thaiv hluav taws xob thaum xub thawj, yog qhov yuav tsum tau muaj.AFDD— lub tshuab hluav taws xob arc fault circuit breaker, tseem hu ua lub cuab yeej nrhiav arc fault, yog ib hom khoom siv tiv thaiv tshiab. Nws tuaj yeem ntes tau qhov arc fault hauv lub voj voog hluav taws xob, thiab txiav lub voj voog ua ntej hluav taws xob, thiab tiv thaiv tau zoo hluav taws xob los ntawm qhov arc fault.
3. Cov chaw siv rau AFDD arc fault circuit breaker yog dab tsi?
Lub tshuab ua haujlwm ntawm lub tshuab hluav taws xob arc fault, lub tshuab hluav taws xob circuit breaker, uas muaj cov chaw soj ntsuam, cov yuam sij ua haujlwm, cov thaiv davhlau ya nyob twg, thiab lub plhaub, thiab cov qauv dav dav. Nws cov qauv tshwj xeeb suav nrog kev sim hluav taws xob cais tawm, cov khoom siv hluav taws xob ib leeg los txheeb xyuas cov teeb meem hluav taws xob feem ntau (xws li microprocessor), kev teeb tsa thiab kev saib xyuas raws li PCB ant colony algorithm, ua qhov kev sim hluav taws xob ntse, kev sib cais hluav taws xob feem ntau.
Ntau yam kev siv tseem ceeb yam tsis muaj qhov muag tsis pom kev ntau yam kev nyab xeeb ntxiv
AFDD arc fault circuit breaker siv dav hauv cov chaw uas muaj cov neeg ua haujlwm coob thiab cov khoom siv hluav taws xob yooj yim hlawv, xws li cov tsev nyob, tsev qiv ntawv, chav tsev so, tsev kawm ntawv thiab lwm yam kev coj noj coj ua thiab pej xeem. Nrog nws lub cev sib dua thiab mos, qhov dav tag nrho tsuas yog 36 hli, uas txuag tau qhov chaw ntawm lub thawv faib khoom, thiab sib xws nrog ntau qhov chaw teeb tsa. Nws dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv hluav taws xob ib txwm muaj.
