Inqaku Lokwenza Uqonde i-AFDD

1. Yintoni i-I-Arc Fault ekhuselweyo yeSekethe Breaker(I-AFDD)?

Ngenxa yoqhagamshelwano olubi okanye umonakalo wokufakelwa kwe-insulation, "i-arc embi" enamandla amakhulu kunye nokushisa okuphezulu kuveliswa kwisiphaluka sombane, okungekho lula ukufunyanwa kodwa kulula ukubangela umonakalo wezixhobo kunye nomlilo.
Imeko ethanda ukuba nee-arcs ezingalunganga
I-Fault arc, eyaziwa ngokuba yintlantsi yombane, ubushushu beziko buphezulu kakhulu, i-metal spatter iyenzeka, kulula ukubangela umlilo.Xa i-arc parallel isenzeka, intambo ephilayo kunye nentambo engathathi hlangothi ayidibanisi ngokuthe ngqo, kuphela ngenxa yokuba ukuguga kwesikhumba kuphulukana neempawu zokugquma okanye ukonakala kwesikhumba, kodwa umgama phakathi kocingo oluphilayo kunye nomgca ongathathi hlangothi usondele kakhulu, kwaye okwangoku. iphula umoya phakathi kocingo oluphilayo kunye nomgca ongathathi hlangothi, kwaye iintlantsi zikhutshwa phakathi kocingo oluphilayo kunye nomgca ongathathi hlangothi.

2. Iimpawu eziqhelekileyo ze-arc ye-voltage ephantsi yefault:

1. Ifomu yangoku yamaza iqulethe ingxolo eninzi ye-frequency ephezulu
2. Kukho i-voltage drop kwi-fault arc
3. isantya sokunyuka kwangoku siqhele ukuba sikhulu kunobume besiqhelo
4. Wonke umjikelo wesiqingatha kukho indawo apho i-current isondele kwi-zero, ebizwa ngokuba yi-"current zero area".
5. I-voltage waveform isondele kuxande, kwaye izinga lokutshintsha kwindawo ye-zero yangoku likhulu kunelo ngamanye amaxesha, kwaye ubuninzi kuxa i-current ingaphezu kwe-zero.
6. I-fault arc idla ngokuphindaphindiweyo, ngamaxesha athile
7. I-waveform yangoku ine-randomness eyomeleleyo
Ukuthintela kunye nokulawulwa komlilo wombane, eyona nto iyingozi yokuqala yomlilo, iya ibaluleke kakhulu.I-Arc Fault circuit breaker (AFDD), i-arc yokukhusela i-switchgear ekhusela umlilo wombane kwindawo yokuqala, iyafuneka.I-AFDD- i-arc fault circuit breaker, eyaziwa ngokuba yi-arc fault device device, luhlobo olutsha lwezixhobo zokukhusela.Iyakwazi ukubona i-arc impazamo kwisiphaluka sombane, kwaye inqumle isiphaluka phambi komlilo wombane, kwaye ikhusele ngokufanelekileyo umlilo wombane obangelwa yi-arc fault.

3. Ziziphi iindawo zokusetyenziswa kwe-AFDD arc fault circuit breaker?

I-Arc fault circuit breaker mechanism, inkqubo ye-circuit breaker, amaziko agqabhukileyo, izitshixo zomsebenzi wokuhlola, iibhloko ze-terminal, isakhelo seqokobhe, njengesakhiwo esiqhelekileyo, ubume bayo bubandakanya isekethe yovavanyo yombane eyedwa, izixhobo zombane zodwa zombane ukuchonga isekethe yempazamo eqhelekileyo ( kuquka microprocessor), uqwalaselo lwenkqubo kunye nokugcinwa esekelwe PCB imbovane koloni algorithm, Qhuba kuvavanyo olukrelekrele yedwa yombane, impazamo eqhelekileyo ucalucalulo yombane wedwa.
Usetyenziso olwahlukeneyo oluphambili ngaphandle kwendawo eyimfama ngakumbi ukhuseleko
I-AFDD arc fault circuit breaker isetyenziswa ngokubanzi kwiindawo ezinabasebenzi abaxineneyo kunye nezixhobo ezinokutsha, njengezakhiwo zokuhlala, amathala eencwadi, amagumbi ehotele, izikolo kunye nezinye izakhiwo zenkcubeko nezoluntu.Idityaniswe nomzimba wayo okhanyayo kunye nobuthathaka, ububanzi bubonke yi-36mm kuphela, egcina kakhulu indawo yebhokisi yokuhambisa, kwaye iyahambelana neendawo ezininzi zofakelo lwejografi.Iba lolona khetho lulungileyo lokuthintela okuqhelekileyo kokujonga umlilo wombane.
