Inqaku Eliza Kukwenza Uqonde I-AFDD

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

Ngenxa yokonakala okungahambelani kakuhle okanye ubushushu obuphezulu, "i-arc embi" enamandla aphezulu kunye nobushushu obuphezulu iveliswa kwisekethe yombane, ekungekho lula ukuyifumana kodwa kulula ukuyibangela umonakalo kwizixhobo kunye nomlilo.
Imeko inokuba nee-arcs ezingalunganga
I-fault arc, eyaziwa ngokuba yi-electric spark, ubushushu obuphakathi buphezulu kakhulu, i-metal spatter iyenzeka, kulula ukuyibangela umlilo. Xa i-parallel arc isenzeka, i-live wire kunye ne-neutral wire azinxibelelani ngqo, kuba ukuguga kwesikhumba se-insulation kulahlekelwa ziimpawu ze-insulation okanye umonakalo wesikhumba se-insulation, kodwa umgama phakathi kwe-live wire kunye ne-neutral line usondele kakhulu, kwaye umbane uphula umoya phakathi kwe-live wire kunye ne-neutral line, kwaye ii-spark zikhutshwa phakathi kwe-live wire kunye ne-neutral line.

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

1. I-waveform yangoku iqulethe ingxolo eninzi ye-high-frequency
2. Kukho ukwehla kwe-voltage kwi-arc ye-fault
3. isantya sokunyuka kwangoku sidla ngokuba sikhulu kunesimo esiqhelekileyo
4. Yonke isiqingatha somjikelo kukho indawo apho umsinga usondele ku-zero, obizwa ngokuba "yindawo ye-zero yangoku".
5. I-voltage waveform ikufutshane nengxande, kwaye izinga lotshintsho kwindawo ye-current zero likhulu kunelo ngamanye amaxesha, kwaye ubuninzi buxa i-current ingaphezulu kwe-zero
6. I-fault arc idla ngokungacwangciswanga, ingenaxesha
7. I-waveform yangoku ine-randomness enamandla
Ukuthintela nokulawula umlilo wombane, oyingozi yokuqala yomlilo, kuya kuba yinto ebaluleke ngakumbi nangakumbi.I-Arc Fault circuit breaker (AFDD), kufuneka isixhobo sokukhusela i-arc esithintela imililo yombane kwasekuqaleni.I-AFDD— i-arc fault circuit breaker, eyaziwa ngokuba sisixhobo sokufumanisa impazamo ye-arc, luhlobo olutsha lwezixhobo zokukhusela. Ingabona impazamo ye-arc kwisekethe yombane, ize inqumle isekethe ngaphambi komlilo wombane, kwaye ithintele ngokufanelekileyo umlilo wombane obangelwa yimpazamo ye-arc.

3. Ziziphi iindawo ezisetyenziswa yi-AFDD arc fault circuit breaker?

Indlela yokusebenza kwe-arc fault circuit breaker, inkqubo ye-circuit breaker, amaziko avulekileyo, izitshixo zomsebenzi wokuhlola, iibhloko zesiphelo, isakhelo seqokobhe, njengolwakhiwo oluqhelekileyo, isakhiwo saso esibonakalayo siquka i-electrical test circuit yodwa, izixhobo ze-elektroniki zodwa zombane ukuchonga i-common fault circuit (kubandakanya i-microprocessor), uqwalaselo lwenkqubo kunye nokugcinwa okusekwe kwi-PCB ant colony algorithm, Qhubeka novavanyo lwe-electrical solidation, ucalucalulo lwe-common fault electric solidation.
Iindlela ezahlukeneyo zokusetyenziswa eziphambili ngaphandle kwendawo engaboniyo yokhuseleko olungaphezulu
I-AFDD arc fault circuit breaker isetyenziswa kakhulu kwiindawo ezinabantu abaninzi kunye nezinto ezisetyenziswa ekutshiseni, njengezakhiwo zokuhlala, amathala eencwadi, amagumbi eehotele, izikolo kunye nezinye izakhiwo zenkcubeko nezoluntu. Idibene nomzimba wayo olula nobuthathaka, ububanzi bayo buyi-36mm kuphela, nto leyo egcina kakhulu indawo yebhokisi yokusasaza, kwaye iyahambelana neendawo ezininzi zokufakela. Iba lolona khetho lufanelekileyo lokuthintela ukujongwa komlilo ngombane.
