Isihloko: Ukuqonda Ukubaluleka kweEarth Leakage Circuit Breakers
ukwazisa
Kwihlabathi lanamhlanje apho ukhuseleko lombane lubaluleke kakhulu,ii-residual current circuit breakers (RCCBs)idlala indima ebalulekileyo ekukhuseleni ukhuseleko lobomi boluntu kunye nempahla.Ngelixa abaninzi besenokuba abaqhelananga neli gama,Ii-RCCBsziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yombane.Eli nqaku lijolise ekucaciseni ukubaluleka kwee-breakers zangoku eziseleyo, umsebenzi wabo kunye neenzuzo zabo ekukhuseleni ukufakwa kombane.
Umhlathi 1: Yintoni iumhlaba ukuvuza yesekethe umaphuli?
Isaphuli sesekethe esishiyekileyo, esibizwa ngokuqhelekileyo njengeI-RCCB, sisixhobo sombane esenzelwe ukukhusela abantu kunye nofakelo lombane kwi-shock yombane kunye neengozi zomlilo ezibangelwa ukuvuza kombane.Ngamafutshane, iI-RCCBibeka iliso kwi-current kwisekethe kwaye ihambe isekethe ukuba ibona ukungalingani kwangoku.Oku kungalingani kunokubangelwa yimisinga yokuvuza, iziphene zokugquma, okanye ukudibana ngqo nabancedisi abaphilayo.
Isiqendu 2: Yenziwa njani i-umsebenzi wokuvuza kwesiphaluka sesiphaluka?
Izaphuli zesekethe zangoku ezivuzayo zixhotyiswe ngee-transformers zangoku ezibuthathaka ezihlala zilinganisa i-current ngokusebenzisa abaqhubi abaphilayo nabangathathi hlangothi.Naliphi na ixesha kukho umehluko phakathi kwegalelo langoku kunye nokubuyisela okwangoku, kubonisa ukuvuza okanye impazamo.II-RCCBibona oku kungangqinelani kwaye ihambe ngokukhawuleza isiphaluka, inqumle amandla ukuthintela umonakalo ongakumbi.
Umhlathi wesithathu: iingenelo zokuvuza kweesekethe zokuvuza
Ukufakela i-breaker circuit breaker yokuvuza kuneenzuzo ezininzi malunga nokhuseleko kunye nokukhusela.Okokuqala, banokunciphisa kakhulu umngcipheko wokutshatyalaliswa kombane ngokufumanisa ukungalingani okuncinci kwisekethe kunye nokuphazamisa amandla ngexesha.Isibini,Ii-RCCBszibalulekile ekukhuseleni imililo ebangelwa ziziphene zombane, njengoko zisabela ngokukhawuleza kumbane ongaqhelekanga, ukunciphisa amandla okushisa kunye ne-arcing.
Ukongezelela, abaphuli beesekethe ezivuzayo banokuqhawula ngokukhawuleza ukunikezelwa kwamandla xa kukho ukuvuza okanye ukungaphumeleli, ukubonelela ngokhuseleko olongezelelweyo lwezixhobo kunye nezixhobo.Ngokwenza njalo, izixhobo ezixabisekileyo zinokukhuselwa ngothintelo kumonakalo onokwenzeka, okukhokelela ekugcinweni kweendleko kunye nobomi obude.
Umhlathi 4: Iindidi zezaphuli zesekethe ezivuzayo
Kukho iintlobo ezimbini eziphambili zeIi-RCCBs: Uhlobo lwe-AC kunye noHlobo lwe-A. Uhlobo lwe-AC lwe-RCCBs lusetyenziswa ngokuqhelekileyo kwiindawo zokuhlala ukubonelela ngokhuseleko kwi-sinusoidal alternating currents.Ezi RCCBs zilungele ukukhuselwa kwimithombo eqhelekileyo yokuvuza efana ne-miswiriring, iingcingo ezonakalisiweyo, kunye nokusilela kwezixhobo.
Uhlobo lwe-RCCBs, ngakolunye uhlangothi, luhamba phambili kwaye lubonelela ngokhuseleko olongezelelweyo ngokubandakanya ukutshintshwa kwangoku kunye ne-pulsating yangoku ngqo (DC).Ezi RCCBs zihlala zifakelwa kwizicelo zobungcali ezingakumbi njengezibhedlele, indawo zoshishino nalapho kusetyenziswa izixhobo zombane ezibuthathaka ngakumbi.Uhlobo lwe-RCCBs luqinisekisa ukhuseleko olupheleleyo kwiimpazamo ze-AC kunye ne-DC ngaphandle kwendawo yokulala.
Isiqendu 5: Ukubaluleka kokuhlala rhoqoI-RCCBuvavanyo kunye nokugcinwa
Ngelixa ii-breaker circuit zangoku ezishiyekileyo ngokungathandabuzekiyo zibalulekile kukhuseleko lombane, kukwabalulekile ukuqonda ukubaluleka kovavanyo nokugcinwa rhoqo.Njengaso nasiphi na esinye isixhobo sombane,Ii-RCCBsiminyaka ngokuhamba kwexesha, ukunciphisa ukusebenza kwabo okanye ukusilela.Ngoko ke, uvavanyo nokugcinwa rhoqo makucwangciselwe ukuqinisekisa ukubaI-RCCBikumgangatho ophezulu kwaye ithintela naziphi na iingozi zombane ezinokuthi zibe kho.
Isiqendu 6: Isiphelo
Ukuqukumbela, ii-breaker circuit zangoku ezishiyekileyo ziyinxalenye yeenkqubo zombane zanamhlanje, zibonelela ngokhuseleko olubalulekileyo ngokuchasene nokutshatyalaliswa kombane kunye neengozi zomlilo.I-RCCB inokubona ukungalingani kwangoku kwaye iphazamise isiphaluka ngexesha, elinokuphucula kakhulu ukhuseleko lokusetyenziswa kombane kunye nokukhusela ubomi kunye nepropati.Ngotyalo-mali kwii-RCCBs ezikumgangatho ophezulu, ukukhetha uhlobo oluchanekileyo kwisicelo ngasinye, kunye nokwenza uvavanyo rhoqo kunye nokugcinwa, sonke sinokwenza indawo yombane ekhuselekileyo yethu kunye nezizukulwana ezizayo.
