Ngenyanga edlule, uchwepheshe kagesi esitshalweni sokukhiqiza wenza iphutha elibonakala lincane ngenkathi egcina i-residual current circuit breaker (RCCB): wabuyisela emuva uxhumano lwentambo yomhlaba ngaphandle kokuhlola kabili. Kungakapheli ihora, kwaba nephutha lokuvuza endaweni yokusebenzela, kodwa i-RCCB yehluleka ukukhubeka, okwabangela ukushaqeka kukagesi esisebenzini futhi kwaphoqa isitshalo ukuba sivale ukuze silungiswe. Lesi sigameko asihlukile—ngaphezu kwama-60% ukwehluleka kwe-circuit breaker kubangelwa ukusebenza okungafanele, okungagcini nje ngokwandisa izindleko zokulungisa kodwa futhi okubangela izingozi ezinkulu zokuphepha. Namuhla, sizochaza amaphutha ama-5 avamile enziwa ochwepheshe kagesi lapho besebenza nazo zonke izinhlobo ze-circuit breaker, bekusiza ukugwema amaphutha nokuqinisekisa ukusetshenziswa kukagesi okuphephile.
Ingozi eyinhloko yokusebenza okungafanele itholakala ekungabonakali kwayo kanye nokubhubhisa kwayo. Amaphutha amaningi amancane, njengokuxhumeka kwe-terminal okuxekethile noma ukulungiswa kwamapharamitha okungahleliwe, angase angabangela ukwehluleka okusheshayo kodwa kancane kancane kuzolimaza ukusebenza kwe-circuit breaker, okuholela ezingozini zokulayisha ngokweqile, i-short circuit, noma ukuvuza ngokuhamba kwesikhathi. Izinhlobo ezahlukene zama-circuit breaker (Ama-Air Circuit Breaker - ACB, Ama-Molded Case Circuit Breaker - MCCB, Ama-Miniature Circuit Breaker - MCB, Ama-Residual Current Circuit Breaker - RCCB, Ama-Residual Current Breaker ane-Overcurrent protection--RCBO) anezakhiwo nemisebenzi ehlukene, ngakho-ke izingozi nezindlela zokugwema zokusebenza okungafanele nazo ziyahlukahluka.
Nazi izindlela ezinhlanu ezivamile zokungafaneleki ochwepheshe bezogesi abavame ukuzenza ngazo zonke izinhlobo zama-circuit breaker, kanye nesiqondiso sochwepheshe sokuzigwema:
Iphutha1(i-ACB): Ukuvala ngesandla ngaphandle kokususa umthwalo, okuholela ekushiseni kokuxhumana, ukujikeleza okufushane, ngisho nokulimala kwe-arc.Isiqondiso:Landela inqubo efanele yokuvala i-ACB ezimweni zomthwalo ophezulu—nquma umthwalo kuqala, hlola isekethe ukuthi ayinamaphutha, bese uvala iswishi ukuze ugweme ukusebenza ngqo ngaphansi komthwalo.
Iphutha2(I-MCCB):Ukuvulwa nokuvalwa okuvamile ngesandla, okuholela ekugugeni kwendlela yokusebenza, ukwehla kwamandla okuphuka, kanye nokuphila kwesikhathi senkonzo okufushane.Isiqondiso:Cacisa imvamisa efanele yokuvulwa nokuvalwa kwe-MCCB—gwema ukusebenza njalo ngesandla ngaphandle uma kudingekile, futhi usebenze ngokuhambisana nencwadi yemiyalelo yemishini.
Iphutha3(i-MCB):Ukushintsha ngokungahleliwe i-MCB ngogesi osezingeni eliphezulu, okuholela ekuvikelweni okungezwani nokushiswa kwemishini ngenxa yokwehluleka ukukhubeka ngesikhathi sokulayisha ngokweqile.Isiqondiso:Khetha i-MCB rated current ngokuya ngomthwalo wangempela—ungalokothi uyishintshe nge-specification enkulu ngokunganaki, njengoba izolahlekelwa umsebenzi wokuvikela ukunqwabelana ngokweqile.
Iphutha 4 (RCCB/RCBO):
I. Imisebenzi Ejwayelekile Engalungile
Amaphutha Ajwayelekile:
1. Ukuxhumeka okuphambene/okungalungile kwezintambo ezingathathi hlangothi nezibukhoma, okulimaza isekethe yokuthola yamanje esele;
2. Ukwehluleka ukwenza izivivinyo zamanje ezisele ezilinganisiwe ngenkinobho yokuhlola isikhathi eside, okuholela ekungavumeleki okungabonakali kwemisebenzi yokuvikela;
3. Ukunciphisa imingcele okungagunyaziwe kwemojuli yokuvikela yamanje eseleyo ukuze kukhutshazwe ngenkani ukuvikelwa okuyinhloko.
Amaphutha Aqondile e-RCCB:
1. Ukusetshenziswa okuzimele kokuvikela ukulayisha ngokweqile/ukujikeleza okufushane (ama-RCCB awanayo imisebenzi yokuvikela ukudlula kwamandla kagesi);
2. Ukulandelana kokufaka okungalungile uma kubhangqwe nama-circuit breaker (ukufaka i-RCCB ngaphambi kwe-circuit breaker).
Amaphutha Aqondile e-RCBO:
1. Ukukhetha kuphela ngamapharamitha wamanje asele ngenkathi ungazinaki ukufanisa umugqa wamanje olinganiselwe wemithwalo, okubangela ukukhubeka njalo komugqa wamanje odlulele;
2. Ukuyisebenzisa nje njengedivayisi yokuvikela yamanje eseleyo futhi yehluleka ukusebenzisa umsebenzi wayo wokuvikela wamanje ohlanganisiwe, okuholela ekuphindaphindeni kwesekethe ngenxa yokuhlanganiswa kwe-circuit breaker okungafuneki.
II. Izinyathelo Ezijwayelekile Zokugwema
1. Hlukanisa kahle izintambo ezingathathi hlangothi neziphilayo ngokuphawula ezindlini; landelai-circuit breaker kuqala, i-RCCB yesibiliukulandelana lapho kubhangqwa i-RCCB nama-circuit breaker;
2.Khetha amadivayisi njengoba kudingeka: Ama-RCCB enzelwe ukuvikela ugesi osele kuphela futhi kumele ahlanganiswe namadivayisi okuvikela ugesi osele; kuma-RCBO, qinisekisa kokubili ugesi osele kanye nogesi olinganiselwe umthwalo ngesikhathi esisodwa;
3. Yenza izivivinyo zomsebenzi wokuvikela wamanje osele nyanga zonke ngenkinobho yokuhlola ekusetshenzisweni kwansuku zonke. Xazulula amaphutha kuqala ngemva kokukhubeka;ukuvala ngenkani noma ukufinyeza i-module yokuvikela akuvunyelwe;
4. Hlola njalo ukuqina kwetheminali kanye nobuqotho bendlu. Shintsha amadivayisi alimele ngemikhiqizo yencazelo efanayo kanye nemingcele; ungahlanganisi ama-RCCB, ama-RCBO noma amadivayisi anemingcele ehlukene.
Iphutha 5 (Zonke izinhlobo zama-circuit breaker): Ama-terminal ezintambo axegayo, okuholela ekukhiqizweni kokushisa, ukushiswa kokuxhumana, kanye ne-short circuit ngesikhathi sokusebenza kwesikhathi eside.
Isiqondiso:Hlola ukuqina kwe-terminal njalo—hlanganisa isakhiwo se-terminal sama-circuit breaker ahlukene ukuqinisekisa amandla okuqinisa afanele, ugweme ukuxega noma ukulimala kwama-terminal.
Ukusebenza ngokuphephile kuyisisekelo sokuphakelwa kukagesi okuthembekile. Ukukhetha ama-circuit breaker asezingeni eliphezulu kanye nokwenza izinqubo zokusebenza zibe zijwayelekile kunganciphisa ngempumelelo izingozi zokwehluleka.ABANTUinezinhlobo eziphelele zama-circuit breaker afakwe izimpawu zokusebenza ezicacile kanye neziqondiso zokuxhuma izintambo, anemiklamo yokuvikela ukuphepha eyakhelwe ngaphakathi ukusiza ochwepheshe bezogesi ukuthi bagweme ukusebenza okungafanele. Uma unemibuzo mayelana nokusebenza kwe-circuit breaker, zizwe ukhululekile ukuxhumana nathi ukuze uthole isiqondiso sochwepheshe.
