Iimeko zokusetyenziswa kwe-RCCB

Iimeko zokusetyenziswa kwee-residual current circuit breakers (RCCB) zibalulekile ekuqinisekiseni ukhuseleko lwabantu kunye nempahla. Ngaphambi kokuba sijonge iimeko ezithile zokusetyenziswa, kubalulekile ukuqonda imigaqo esisiseko yombane kunye nendima ye-RCCB ekuthinteleni umbane.

Ukothuka kombane kukwenzakala okukhulu okubangelwa kukudlula kombane emzimbeni womntu. Xa izandla zomntu zidibana nocingo oluphilayo, umbane unokuhamba emzimbeni, nto leyo enokubangela ukwenzakala. Emva kokuba kubekho ukothuka kombane, umbane kufuneka unqunyulwe ngokukhawuleza. Ixesha elimiselweyo lokunqumla umbane lixhomekeke kubungakanani bombane ohamba emzimbeni. Umzekelo, ukuba umbane yi-50mA, ixesha lokunqunyulwa kufuneka libe ngaphakathi kwesekhondi e-1. Ukuba umbane yi-500mA, ixesha lokunqunyulwa lifinyezwa libe yimizuzwana eyi-0.1.

A I-Residual Current Breaker eseleyo (I-RCCB) sisixhobo sokhuseleko lombane esenzelwe ukuqhawula umbane ngokuzenzekelayo xa kukho ukuvuza okanye ukutshayiswa kombane. Xa umbane ufikelela kwixabiso langoku lokusebenza elimiselwe yiswitshi yokukhusela, i-RCCB iyawunqumla umbane kwixesha eliqingqiweyo ukuqinisekisa ukhuseleko lwabantu kunye nempahla. Oku kwenza i-RCCB ibe yinxalenye ebalulekileyo yokhuseleko lombane kwiimeko ezahlukeneyo zokusetyenziswa.

Iimeko zokusetyenziswa kwe-RCCB zahlukile kwaye zigubungela uluhlu olubanzi. Enye yezona meko ziphambili ibandakanya imigca yokusasazwa kwezixhobo zombane eziphathwayo nezihambayo, kunye nezixhobo ezizinzileyo apho abantu basenokungakwazi ukuphuma kuzo ngexesha xa kukho umbane. Ukongeza, izixhobo zombane kwiindawo zokusebenza zangaphandle kunye neesekethe zezixhobo zasekhaya okanye iisekethe zesokhethi kufuneka zixhotyiswe ngee-RCCB ezinexabiso elilinganiselweyo langoku lokusebenza elingadluli kwi-30mA. Oku kuqinisekisa ukuba abantu bakhuselekile kwiingozi zokothuka kombane ezinokubakho kwezi ndawo.

Enye imeko ebalulekileyo yokusetyenziswa kwe-RCCB kukukhanyisa i-elevator shaft eqhutywa yi-AC 220V. Kule meko, i-voltage yombane efanelekileyo yokukhanyisa i-elevator shaft yi-36V. Nangona kunjalo, xa usebenzisa i-AC 220V, kufuneka kufakwe i-RCCB ukuze kubonelelwe ngokhuseleko olongezelelweyo. Ukongeza, umthombo wokukhanya kufuneka uxhotyiswe ngesigqubuthelo sokukhusela ukunciphisa umngcipheko wokutshayiswa ngumbane.

Ngamafutshane, iimeko zokusetyenziswa kwee-residual current circuit breakers (RCCB) zibalulekile ekuthinteleni ukutshayiswa ngombane nokuqinisekisa ukhuseleko lwabantu kunye nempahla. Ukususela kwizixhobo zombane eziphathwayo nezihambayo ukuya kwiisekethe zezixhobo zasekhaya kunye nokukhanyisa i-elevator shaft, ii-RCCB zidlala indima ebalulekileyo ekuthinteleni iziphumo eziyingozi zokutshayiswa ngombane. Ngokuqonda nokusebenzisa iimeko ezifanelekileyo zokusetyenziswa kwe-RCCB, abantu kunye nemibutho banokudala imeko-bume ekhuselekileyo kwaye banciphise umngcipheko weengozi zombane.
