Uzichonga Njani Iindidi zoMqhekezi weSekethe?

2020-12-29

Izaphuli zesekethezizixhobo zokhuseleko ezisisiseko kwisakhiwo ngasinye, indawo yokugcina impahla kunye nazo zonke izakhiwo.Basebenza njengamaqela esithathu okanye abalamli kwiinkqubo ezintsonkothileyo neziyingozi zombane.Xa udibana nombane ogqithisileyo, inkqubo yocingo inokubangela imililo, ukunyuka kunye nokuqhuma.Kodwa ngaphambi kokuba kwenzeke ingozi enjalo,i-breaker circuit iya kungenelela ngokunqumla umbane.

Ezi zixhobo ezifana nebhokisi zisebenza ngokukhawulela okwangoku kwisekethe enye.Ngaphandle kwe-breaker circuit, indawo yakho iya kuba yingozi rhoqo kunye nesiphithiphithi.

Kufuneka uthenge i-spare okanye i-breaker circuit eyongezelelweyo kwiphaneli.Kodwa nje ukuba uqale ukuthenga ngeenxa zonke, uya kuqonda ukuba kukho amawaka ee-breaker zesekethe ongakhetha kuzo.Kwiipaneli zorhwebo okanye zoshishino, eli nani linokuba likhulu ngakumbi.

Ukuthenga i-breaker circuit akukho lula, ngoko uqinisekisa njani ukuba wenze isigqibo esifanelekileyo?Kuvela ukuba ukukhetha i-breaker circuit echanekileyo ayinzima kakhulu, kwaye yonke into iqala ngokufundaindlela yokuchonga iintlobo ezahlukeneyo zabaphuli beesekethe.

Ngoko ke ungazichonga njani iintlobo zezaphuli zesekethe? Zingaphi iindidi zezaphuli ezikhoyo?

Kukho iintlobo ezintathu eziphambili zezaphuli zesekethe:abaphuli beesekethe eziqhelekileyo,I-AFCI i-circuit breakerskwayeIzaphuli zeGFCI.Nantsi into ekufuneka uyazi malunga nabo:

Iintlobo ze-Circuit Breaker

1. Abaqhankqalazi beSekethe abaMgangatho

Kukho iindidi ezimbini zezaphuli zesekethe eziqhelekileyo:abaphuli beesekethe zepali enyekwayeabaqhekeza iipali ezimbini.Ezi ziqhekeza ezilula ezibeka iliso kwi-cadence yombane njengoko ujikeleza indawo engaphakathi.Ilandelela umbane kwiinkqubo zeentambo zombane, izixhobo zombane kunye neesokethi. Olu hlobo lwe-circuit breaker blocks current ngexesha lokugqithisa kunye neesekethe ezimfutshane ukukhusela iingcingo ekugqithiseni.Oku kunokwenzeka xa enye intambo eshushu ichukumisa ucingo oluphantsi, olunye ucingo olushushu okanye ucingo olungathathi hlangothi.Umsebenzi wangoku wokusika unokuthintela imililo yombane.I-1-intshi ye-circuit breaker esetyenziswa kwindawo yokuhlala idla ngokuba yi-single-pole breaker circuit kwaye ithatha i-slot kwipaneli.I-bipolar circuit breakers ixhaphake kakhulu kwiizixhobo zekhaya ezinkuluokanyeizibonelelo zorhwebo, ehlala kwiindawo zokubeka ezimbini.Abaqhekezi beesekethe eziqhelekileyoukukhusela ipropati, izixhobo kunye nezixhobo zombane ngenxa yeempazamo zombane.

I-Single-Pole Breakers——Esona saphuli-mthetho sixhaphakileyo;Ikhusela ucingo olunye olunamandla;Ibonelela nge-120V kwisekethe

I-Double-Pole Breakers——Inezaphuli-mthetho ezibini ezinesiphatho kunye nendlela yohambo ekwabelwana ngayo;Ikhusela iingcingo ezimbini;Ibonelela nge-120V/240V okanye i-240V kwisekethe;Iza kwi-15-200 amps;Isetyenziselwa izixhobo ezinkulu ezifana nezifudumezi zamanzi

AC Circuit Breaker

2. GFCI Circuit Breakers

I-GFCI i-circuit breaker okanye i-fault fault circuit breaker inqumla umbane kwisiphaluka xa kukho umbane ogqithisiweyo.Baphinda basebenze xa kwenzeka isiphaluka esifutshane okanye umgca womgca wecala.Okokugqibela kwenzeka ekubunjweni kweendlela ezinobungozi phakathi kwezinto zangoku kunye nezisekelwe phantsi.Ezi zaphuli zesekethe ziayilungelanga izixhobo zokusebenza ngokuqhubekayonjengeifrijiokanyeizixhobo zonyango.Isizathu sesi ukukhubeka.I-breaker circuit inokukhubeka ngaphezu kokuba ifanele.Kwiindawo ezifumileyo ezifanaamakhitshi, amagumbi okuhlambela, okanyeiindawo zoshishino ezifumileyo, uya kuhlala udibana neziseko ezinamaqhosha amabini ("uvavanyo" kunye "nokusetha kwakhona"), ezikhuselwe ngabaphuli beesekethe ze-GFCI.I-GFCI i-circuit breakers ibonakala ihluke kwi-breaker circuit breakers: banamaqhosha "okuvavanya" kunye nokucima / ukuvala.I-GFCI i-circuit breaker ichazwa yi-coil wire kunye neqhosha lokuvavanya ngaphambili.Kuyimfuneko kakhulu kwiindawo ezimanzi ezifanaamagumbi angaphantsi,izithuba zangaphandle,amagumbi okuhlambela,amakhitshikwayeigaraji.Ilungele izitishi zokusebenzela usebenzisa izixhobo zamandla.Iplagi nganye yemagnethi inomgangatho othi "I".

3.AFCI Circuit Breakers

I-AFCI i-circuit breakers okanye i-arc fault circuit breakers inokuthintela ukukhutshwa ngengozi kwiintambo okanye kwiinkqubo zocingo.Ikwenza oku ngokubona iindlela ezingaqhelekanga kunye notshintsho lombane, kwaye emva koko ikhuphe isiphaluka esonakeleyo kumthombo wamandla ngaphambi kokuba i-arc ibambe ubushushu obaneleyo ukuze kubangele ilangatye.Ezi ziqhekeza zesekethe zithintela ukukhutshwa kombane kwaye ngaloo ndlela ziphephe imililo yombane ebangelwa yimingcipheko efana nenkqubo endala yocingo.Njenge-GFCI, nabo baneqhosha "lokuvavanya".Nangona i-AFCI ifana ne-GFCI, inokuthintela iintsilelo ezimbini ezahlukeneyo.Kwimeko,I-AFCI inokuthintela umlilo, kwayeI-GFCI inokuthintela ukothuka kombane.Abaphuli beesekethe ze-AFCI banoxanduva lokukhusela i-wiring yesiphaluka sesebe kwiinkqubo zombane kwaye kufuneka isetyenziswe kunye nesiqhelo okanye i-standard circuit breakers kuba isabela kwi-stable heat supply kunokuguquguquka okukhawulezayo.

Ngaphandle koko, iipaneli ezahlukeneyo ziya kuxhasa izaphuli zesekethe ezahlukeneyo ngokwemigaqo yokuvelisa kunye nolungelelwaniso lomzimba.Ngokuqhelekileyo, uya kufumana ileyibhile ene-breaker circuit efanelekileyo ngaphakathi kwepaneli.
