Isihloko Esizokwenza Uqonde I-AFDD

1. KuyiniI-Arc Fault Protected Circuit Breaker(I-AFDD)?

Ngenxa yokulimala kokuthintana noma kokushisa okuncane, "i-arc embi" enamandla aphezulu kanye nokushisa okuphezulu ikhiqizwa kusekethe kagesi, okungelula ukuyithola kodwa okulula ukuyibangela umonakalo wemishini ngisho nomlilo.
Isimo sivame ukuba nama-arcs angalungile
I-fault arc, eyaziwa kakhulu ngokuthi i-electric spark, izinga lokushisa eliphakathi liphezulu kakhulu, kwenzeka i-metal spatter, kulula ukuyibangela umlilo. Uma kwenzeka i-parallel arc, i-live wire kanye ne-neutral wire azixhumani ngqo, ngoba ukuguga kwesikhumba sokuvikela kulahlekelwa izici zokuvikela noma ukulimala kwesikhumba sokuvikela, kodwa ibanga eliphakathi kwe-live wire kanye ne-neutral line liseduze kakhulu, futhi ugesi uphula umoya phakathi kwe-live wire kanye ne-neutral line, futhi izinhlansi zikhishwa phakathi kwe-live wire kanye ne-neutral line.

2. Izici ezijwayelekile ze-arc yephutha eliphansi lamandla aphansi:

1. I-waveform yamanje iqukethe umsindo omningi wemvamisa ephezulu
2. Kukhona ukwehla kwamandla kagesi ku-arc yephutha
3. isivinini sokukhuphuka kwamanje ngokuvamile sikhulu kunesimo esijwayelekile
4. Njalo ngesigamu somjikelezo kunendawo lapho umsinga useduze no-zero, obizwa ngokuthi “indawo yo-zero yamanje”.
5. I-voltage waveform iseduze nonxande, futhi izinga lokushintsha endaweni yamanje engu-zero likhulu kunelezinye izikhathi, futhi esiphezulu yilapho ugesi ungaphezu kuka-zero
6. I-arc yamaphutha ivame ukwenzeka ngezikhathi ezithile, ngezikhathi ezithile
7. I-waveform yamanje inokungahleliwe okunamandla
Ukuvimbela nokulawula umlilo kagesi, okuyingozi yokuqala yomlilo, kuya ngokuya kuba yinto ebaluleke kakhulu.I-Arc Fault circuit breaker (AFDD), kudingeka iswishi yokuvikela i-arc evimbela imililo kagesi kwasekuqaleni.I-AFDD— i-arc fault circuit breaker, eyaziwa nangokuthi idivayisi yokuthola amaphutha e-arc, uhlobo olusha lwezinto zokuvikela. Ingathola amaphutha e-arc ku-electric circuit, futhi inqume i-electric circuit ngaphambi komlilo kagesi, futhi ivimbele ngempumelelo umlilo kagesi obangelwa yi-arc fault.

3. Yiziphi izindawo zokusetshenziswa kwe-AFDD arc fault circuit breaker?

Indlela yokusebenza kwe-arc fault circuit breaker, uhlelo lwe-circuit breaker, izikhungo ezifiphele, okhiye bomsebenzi wokuhlola, amabhlogo we-terminal, uhlaka lwegobolondo, njengesakhiwo esijwayelekile, isakhiwo saso esiyingqayizivele sihlanganisa isekethe yokuhlola ehlukanisiwe kagesi, izingxenye ze-elekthronikhi ezihlukanisiwe zikagesi ukuhlonza isekethe yamaphutha evamile (kufaka phakathi i-microprocessor), ukucushwa kwesistimu kanye nokugcinwa okusekelwe ku-algorithm ye-PCB ant colony, Qhubeka nokuhlolwa kwe-elekthronikhi okuhlakaniphile, ukuhlukaniswa kwe-elekthronikhi okuhlukanisiwe okuvamile.
Ukusetshenziswa okuyinhloko okuhlukahlukene ngaphandle kwesici sokuphepha esibonakalayo
I-AFDD arc fault circuit breaker isetshenziswa kabanzi ezindaweni ezinabantu abaningi kanye nezinto zokusetshenziswa ezivuthayo, njengezakhiwo zokuhlala, imitapo yolwazi, amakamelo amahhotela, izikole kanye nezinye izakhiwo zamasiko nezomphakathi. Uma kuhambisana nomzimba wayo olula futhi othambile, ububanzi obuphelele bungama-36mm kuphela, okusindisa kakhulu indawo yebhokisi lokusabalalisa, futhi kuhambisana nezindawo eziningi zokufakwa. Iba yisinqumo esihle kakhulu sokuvimbela okuvamile ukuqapha umlilo kagesi.
