I-RCD Circuit Breaker: Isixhobo soKhuseleko oluBalulekileyo kwiiNkqubo zoMbane

IIsixhobo Sangoku esiSisalela (RCD), ekwabizwa ngokuba yi-aIsaphuli seSekethe yangoku eshiyekileyo (RCCB), ibalulekile kwi iinkqubo zombane. Ithintela ukothuka kombane kwaye inciphisa iingozi zemililo yombane. Esi sixhobo sisixhobo esinovakalelo oluphezulu olujonga ukuhamba komsinga wombane kwisekethi kwaye sikhuphe ngokukhawuleza unikezelo lombane xa kukho impazamo, njengaxa umsinga uvuza emhlabeni (umhlaba).

Intshayelelo kuRCD Circuit Breakers

An RCD umaphuli wesekethe yenzelwe ukubeka iliso kwibhalansi yangoku ehambayo nge-conductor ephilayo okanye engathathi hlangothi kwiisekethe zombane. Ngaphantsi kweemeko eziqhelekileyo zokusebenza, i-current ejikelezayo kwi-conductor ephilayo kufuneka ilingane ne-current flowing through conductor neutral. Nangona kunjalo, xa kufunyenwe impazamo, njengesixhobo esonakeleyo okanye iingcingo ezingasebenzi kakuhle, umsinga unokuvuza phantsi, udale iintsalela yangoku. I-RCD ibona oku kungalingani kwaye ijikeleza isiphaluka, inqumle ukunikezelwa kombane kwii-milliseconds.

Ezi mpendulo zikhawulezayo zinceda ukuthintela ukothuka okunokwenzeka kombane kunye nokunciphisa umngcipheko womlilo ngezixhobo zombane ezingasebenziyo. Ukusetyenziswa kwee-RCD kubaluleke kakhulu kwiindawo ezinomngcipheko owongeziweyo, njengendawo emanzi (umzekelo, amagumbi okuhlambela, amakhitshi kunye neendawo zangaphandle) kunye neendawo zokwakha.

Isebenza njani i-RCD Circuit Breakers

Ukusebenza kweRCD isixhobo sangoku esishiyekileyo kumgaqo wokufumanisa ukungalingani phakathi kokuphila (isigaba) kunye nemisinga engathathi hlangothi. Kwinkqubo yombane esebenza ngokugqibeleleyo, ikhoyo ngoku ingena ngeekondaktara eziphilayo kufuneka ibuye ngeekondaktari ezingathathi hlangothi. Ukuba i-RCD ibona nokuba kukho ukuvuza okuncinci okukhoyo emhlabeni (ngokuqhelekileyo i-30 milliamps okanye ngaphantsi), iya kuhamba isekethe.

Nantsi indlela iRCD umaphuli wesekethe imisebenzi:

1. Ukusebenza okuqhelekileyo: Kwiimeko eziqhelekileyo, imisinga ephilayo kunye nengathathi hlangothi ilungelelene, kwaye i-RCD ayithathi nayiphi na into, ivumela ukuba iinkqubo zombane zisebenze njengoko kulindelwe.
2. Ukufunyanwa kokuvuza kwangoku: Xa kukho impazamo yomhlaba okanye ukungaphumeleli kwe-insulation kwisixhobo okanye iingcingo, ukuvuza kwangoku ukusuka kumqhubi ophilayo ukuya emhlabeni, ukudala ukungalingani phakathi kwemisinga ephilayo kunye nengathathi hlangothi.
3. I-Trigger Mechanism: I-RCD i-circuit breakers ibeka iliso ngokuqhubekayo ukuhamba kwangoku. Ukuba ibona ukuvuza kwangoku (intsalela yangoku) engaphaya kwemida ebekiweyo (idla ngokuba yi-30mA), isixhobo siqalisa indlela yohambo.
4. Uqhawulo oluKhawulezayo: Ngaphakathi kwee-milliseconds zokufumanisa impazamo, i-RCD inqamula ukunikezelwa kwamandla kwisiphaluka esichaphazelekayo, ukukhusela ukutshatyalaliswa kombane okanye umlilo wombane.

Iintlobo ze-RCD Circuit Breakers

Imida ye-RCD Circuit Breakers

NgelixaRCD izixhobo zangoku ezishiyekileyo ziyasebenza ekuthinteleni ukothuka kombane kunye nemililo, zinemida ethile:

• Ababoneleli ngoKhuseleko olugqithisileyo okanye uKhuseleko lweSekethe emifutshane: I-RCD yenzelwe ukufumanisa iimpazamo zomhlaba kunye nemisinga eseleyo, kodwa ayikhuseli ngokugqithiswa okanye kwiisekethe ezimfutshane. Ukukhusela ngokupheleleyo, i-RCD kufuneka isetyenziswe ngokubambisana nabanye abaphuli beesekethe okanye iifuse ezinikezela ngokugqithiswa kunye nokukhusela isiphaluka esifutshane.
• Uhambo lwenkathazo: Kwezinye iimeko,RCD zesekethe breakers inokukhubeka ngokungeyomfuneko ngenxa yokuvuza okuncinci kwangoku okanye iimpazamo ezidlulayo. Noko ke, iingenelo zokhuseleko ziyodlula lee inkxwaleko yokukheth’ inkathazo ngamaxesha athile.
• Akukho khuselo ngokuchasene neempazamo zomgca-ukuya-kuPhakathi: Ii-RCD zikhusela kuphela kwiimpazamo zomhlaba, kungekhona iimpazamo ezenzeka phakathi kwabaqhubi abaphilayo kunye nabangathathi hlangothi. Izixhobo ezongezelelweyo zokukhusela ziyafuneka ukwenzela ukhuseleko olubanzi lwesekethe.

UVavanya njani i-RCD Circuit Breakers

Uvavanyo lwarhoqo lweRCD izixhobo zangoku ezishiyekileyo kubalulekile ukuqinisekisa ukusebenza kwazo. Uninzi lwe-RCDs luza neqhosha lokuvavanya elifanisa impazamo ngokudala ukungalingani okuncinci kwangoku. Xa iqhosha lovavanyo licinezelwe, iRCD umaphuli wesekethe kufuneka ikhubeke ngoko nangoko, nto leyo ebonisa ukuba isebenza kakuhle. Kucetyiswa ukuba kuvavanywe ii-RCDs ubuncinane kanye kwiinyanga ezintandathu ukuqinisekisa ukuthembeka kwazo.

Ukuqukumbela

I (I-RCD), kwaziwa njenge (RCCB), sisixhobo esibalulekileyo sokhuseleko esibonelela ngokhuseleko ekutshisweni kombane nakwimililo yombane. Ngokubeka iliso kwiisekethe zombane kwiimpazamo zomhlaba kunye nokuqhawula ngokukhawuleza unikezelo lwamandla xa kukho impazamo,RCD zesekethe breakers dlala indima ebalulekileyo ekwandiseni ukhuseleko lofakelo lombane. Ukusetyenziswa kwabo kubaluleke kakhulu kwiindawo ezinomngcipheko okhulayo, njengendawo emanzi kunye neendawo zokwakha, apho umngcipheko weengozi zombane uphezulu. Kuba nabani na ofuna ukhuseleko lweenkqubo zabo zombane, ukufaka ii-RCDs linyathelo elibalulekileyo lokunciphisa iingozi kunye nokukhusela abantu kunye nepropathi.
