Isihloko Sokwenza Uqonde I-AFDD

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

Ngenxa yokuxhumana okungalungile noma ukulimala kokufakelwa, "i-arc embi" enamandla amakhulu kanye nokushisa okuphezulu kukhiqizwa kumjikelezo kagesi, okungelula ukutholakala kodwa kulula ukubangela ukulimala kwemishini ngisho nomlilo.
Isimo sithambekele kuma-arcs anephutha
I-fault arc, eyaziwa ngokuthi yi-electric spark, izinga lokushisa eliphakathi liphezulu kakhulu, i-spatter yensimbi iyenzeka, kulula ukudala umlilo.Lapho i-arc ehambisanayo yenzeka, intambo ephilayo kanye nentambo engathathi hlangothi ayithintani ngqo, kuphela ngoba ukuguga kwesikhumba kulahlekelwa izici zokuhlukanisa noma ukulimala kwesikhumba, kodwa ibanga phakathi kwentambo ephilayo kanye nomugqa ophakathi nendawo liseduze kakhulu, futhi lamanje. iphula umoya phakathi kwentambo ebukhoma nolayini ophakathi nendawo, futhi izinhlansi ziyaphuma phakathi kwentambo ebukhoma nolayini ophakathi nendawo.

2. Izici ezijwayelekile ze-low-voltage fault arc:

1. I-waveform yamanje iqukethe umsindo omningi we-high-frequency
2. Kukhona ukwehla kwamandla kagesi ku-arc yephutha
3. isivinini samanje sokukhuphuka ngokuvamile sikhulu kunesimo esivamile
4. Njalo ngesigamu somjikelezo kunendawo lapho i-current isondele ku-zero, ebizwa ngokuthi "indawo ye-zero yamanje".
5. I-voltage waveform iseduze kukanxande, futhi izinga lokushintsha endaweni yamanje enguziro likhulu kunalelo ngezinye izikhathi, futhi umkhawulo kulapho owamanje ungaphezu kukaziro.
6. I-fault arc ivamise ukuba yizikhathi ezithile, izikhawu
7. I-waveform yamanje inokungahleliwe okuqinile
Ukuvimbela nokulawulwa komlilo kagesi, okuyingozi yokuqala yomlilo, kuya ngokuya kubaluleke kakhulu.I-Arc Fault circuit breaker (AFDD), i-switchgear yokuvikela i-arc evimbela imililo kagesi kwasekuqaleni, iyadingeka.I-AFDD— i-arc fault circuit breaker, eyaziwa nangokuthi i-arc fault device, iwuhlobo olusha lwemishini yokuzivikela.Ingakwazi ukubona iphutha le-arc kumjikelezo kagesi, futhi inqamule isekethe ngaphambi komlilo kagesi, futhi ivimbele ngempumelelo umlilo kagesi obangelwa iphutha le-arc.

3. Yiziphi izindawo ezisetshenziswayo ze-AFDD arc fault circuit breaker?

I-Arc fault circuit breaker mechanism, isistimu ye-circuit breaker, izikhungo ezigqamile, okhiye bokusebenza bokuhlola, amabhulokhi wokugcina, ifreyimu yegobolondo, njengesakhiwo esijwayelekile, ukwakheka kwayo okubandakanya isekethe yokuhlola ehlukanisiwe kagesi, izakhi zikagesi zodwa ukuhlonza isekethe yephutha elivamile ( okuhlanganisa i-microprocessor), ukucushwa kwesistimu nokugcinwa okusekelwe ku-algorithm ye-PCB intuthwane, Qhubeka nokuhlola okuhlakaniphile koyedwa kagesi, iphutha elivamile lokubandlululwa koyedwa kukagesi.
Izinhlobonhlobo zokusetshenziswa okuyinhloko ngaphandle kwendawo eyimpumputhe into yokuphepha eyengeziwe
I-AFDD arc fault circuit breaker isetshenziswa kabanzi ezindaweni ezinabasebenzi abaminyene nezinto zokusetshenziswa ezingashi, njengezakhiwo zokuhlala, imitapo yolwazi, amagumbi amahhotela, izikole nezinye izakhiwo zamasiko nezomphakathi.Ihambisana nomzimba wayo ongasindi futhi ontekenteke, ububanzi obuphelele bungama-36mm kuphela, okusindisa kakhulu indawo yebhokisi lokusabalalisa, futhi iyahambisana nezindawo eziningi zokubeka indawo.Iba yisinqumo esingcono kakhulu sokuvimbela okujwayelekile kokuqapha umlilo kagesi.
