Zisetyenziswa phi iibreaker zeSekethe kunye nendlela yokukhetha echanekileyo

Ziphi ii Abaqhekezi beSekethe Isetyenzisiwe kunye nendlela yokukhetha eLungileyo?

Izaphuli zesekethe zizixhobo zokhuseleko ezibalulekileyo ezisetyenziselwa ukukhusela iinkqubo zombane kwi-overcurrent, overloads, kunye neesekethe ezimfutshane. Xa kubhaqwe impazamo, ngokuzenzekelayo ziphazamisa ukuhamba kombane ukunqanda umlilo, ukonakala kwesixhobo, okanye ukothuka kombane.

Iimeko zeSicelo saBaphuli beeSekethe

Iisetingi zokuhlala
Emakhaya, ii-circuit breakers zifakwe kwiipaneli zombane ukukhusela iisekethe zokukhanyisa, izixhobo zendlu kunye neendawo zombane. Banceda ukukhusela imililo yombane kunye nokuqinisekisa ukusebenza okukhuselekileyo kwezixhobo zemihla ngemihla.

IiNdawo zoRhwebo
Eziofisini, kwiivenkile ezithengisayo, nakwizakhiwo zikawonke-wonke, abaphuli beesekethe bakhusela iinkqubo zeHVAC, izibane, izinyusi nezinye izixhobo. Bafaka isandla ekuthembekeni kokusebenza kunye nokhuseleko lwamandla.

Izicelo zoShishino
Iifektri kunye nezityalo zemizi-mveliso zisebenzisa ii-breakers zesekethe ukukhusela oomatshini abanzima, iimoto kunye neenkqubo zamandla. Ezi ndawo zihlala zibandakanya imisinga ephezulu kwaye zifuna iziqhekeza ezinomthamo omkhulu kunye nokuqina.

IiNkqubo eziZodwa
Ii-Circuit breakers nazo zibalulekile kwiinkqubo zamandla elanga, amaziko edatha, kunye neziseko zothutho, apho ukhuseleko oluthembekileyo luyimfuneko ekusebenzeni okungaphazamisekiyo.

Ngubani osebenzisa ii-Circuit Breakers?

Izaphuli zesekethe zisetyenziswa kwaye zilondolozwe luluhlu lwabantu ngabanye:

• Iingcali zombane ufake, uhlole, kwaye ubeke endaweni izaphuli kwiindawo zokuhlala kunye nezorhwebo.

• Iinjineli iisistim zokuyila kwaye zichaze izaphuli ezihlangabezana neemfuno zobugcisa nezokhuseleko.

• Abaphathi beZiko ukubeka iliso kwiinkqubo zokuqhawula ukugcina ukhuseleko lwesakhiwo kunye nokuthintela ixesha lokuphumla.

• Abaninimzi inokusebenzisana namaqhekeza ngexesha lokuphucula, ukulungiswa, okanye ukubuyisela amandla.

Indlela yokukhetha i-Right Circuit Breaker

Ukukhetha i-breaker circuit efanelekileyo kufuna ukuvavanya ngononophelo iimpawu zenkqubo yakho. Imiba ephambili ekufuneka iqwalaselwe ibandakanya:

1. I-Voltage kunye neeReyithingi zangoku

Qinisekisa ukuba i-breaker ihambelana nombane wenkqubo yakho kunye neemfuno zangoku.

• I-Voltage:

  • Iinkqubo zokuhlala ngokuqhelekileyo zisebenzisa i-120V okanye i-240V (eMntla Melika), okanye i-230V (iYurophu).

  • Iinkqubo zorhwebo nezoshishino zinokufuna i-480V okanye ngaphezulu.

• Okwangoku:

  • I-15A–20A yokukhanyisa ngokubanzi kunye neendawo zokuphuma

  • I-30A–50A yezixhobo ezinkulu ezifana nee-oveni kunye nezomisi

  • 100A okanye ngaphezulu izixhobo zoshishino

Qhagamshelana neenkcukacha zenkqubo yakho okanye igcisa lombane ukumisela eyona mfuno.

2. Inani leePali

Inani leepali lixhomekeke kuhlobo lwesekethe:

• Ipali enye iziqhekeza zisetyenziselwa iisekethe ze-120V, ezifana nezibane zasekhaya okanye iindawo zokuphuma.

• Ipali ephindwe kabini ii-breakers zibamba iisekethe ze-240V zezixhobo ezifana nezomisi okanye izifudumezi zamanzi.

• Iipali ezininzi abaqhekezayo basetyenziswa kwiinkqubo zezigaba ezintathu eziqhelekileyo kwiindawo zoshishino.

3. Ukwaphulwa kweSakhono

Ukuqhawula amandla yimpazamo enkulu yangoku i-breaker inokuphazamisa ngaphandle kokusilela.

• Iindawo zokuhlala zidla ngokufuna i-6kA ukuya kwi-10kA.

• Iindawo zorhwebo nezoshishino zinokufuna i-25kA okanye ngaphezulu, kuxhomekeke kuyilo lwenkqubo.

Ukukhetha i-breaker enomthamo ongonelanga wokophuka kunokukhokelela ekungasebenzini kwesixhobo. Kudla ngokucetyiswa ukuba kuvumeleke umda wokhuseleko ongaphezulu komjelo wempazamo obaliweyo.

4. Iigophe zohambo lwe-MCB

Iigophe zohambo zimisela ukuba isantya esincinci sesaphuli sesekethe (MCB) siphendula ngokukhawuleza kangakanani na kwi-overcurrent:

• B Ijika: Uhambo ngamaxesha angama-3-5 alinganiswe ngoku; ilungele ukukhanyisa kunye nemithwalo yendawo yokuhlala ngokubanzi.

• C Ijika: Uhambo kwii-5-10 amaxesha alinganiswe ngoku; isetyenziswe ngeenjini okanye izixhobo ezine-inrush ephakathi.

• D Ijika: Uhambo kwii-10-15 amaxesha alinganiswe ngoku; ilungele iinjini ezinzima okanye ii-transformers.

Khetha ijika elisekelwe kumhla olindelekileyo wokuqalisa wesixhobo.

5. Iimpawu ezongezelelweyo zoKhuseleko

Izaphuli zale mihla zinokubandakanya izinto ezahlukeneyo zokukhusela ukomeleza ukhuseleko:

• Iziphazamisi zeSekethe yeGround Fault (GFCI) ukubona iimpazamo zomhlaba kwaye zifuneka kumagumbi okuhlambela, ekhitshini, okanye kwiindawo ezingaphandle.

• I-Arc Fault Circuit Interrupters (AFCI) qaphela iimeko ezinobungozi ze-arcing, ezisetyenziswa ngokuqhelekileyo kumagumbi okulala kunye neendawo zokuhlala.

• UKhuseleko lweSurgery inceda ukukhusela izinto zombane ezibuthathaka kwi-voltage spikes.

• Ukubeka iliso ngobuchule ivumela uhlaziyo lwexesha lokwenyani, ukulandelwa kokusetyenziswa kwamandla, kunye nolawulo olukude.
