Amanyathelo okuzikhusela xa usebenzisa i-RCBO

I-Residual current breaker (RCBO) enomsebenzi wokukhusela i-overcurrent yinto ebalulekileyo ukuqinisekisa ukhuseleko lweenkqubo okanye izixhobo ezine-voltage ephantsi. Ayinakuthintela kuphela iingozi zombane kunye nokukhusela ukhuseleko lomntu, kodwa ikwajonga imeko yokufakelwa komhlaba. Nangona kunjalo, kubalulekile ukuqonda ukuba ukufaka i-RCBO akuqinisekisi ukhuseleko olungenamsebenzi. Kufuneka sigxile ekuthinteleni nasekusebenziseni amanyathelo obuchwephesha okhuseleko ahlukeneyo ukuze kufezekiswe ukusetyenziswa kombane ngokukhuselekileyo. I-RCBO lukhuselo olongezelelweyo phakathi kwamanyathelo okhuseleko asisiseko. Ulawulo olucokisekileyo kunye nokwazisa kunye nemfundo malunga nokusetyenziswa kombane ngokukhuselekileyo ziziqinisekiso ezisisiseko zokhuseleko.

Into enye ekufuneka uyikhumbule xa usebenzisa i-RCBO kukuba inokukhusela umzimba womntu kuphela xa kwenzeka ingozi yombane yesigaba esinye. Ukuba umzimba womntu ugqunywe ngumoya emhlabeni kwaye udibana nemigca emibini yesigaba okanye umgca omnye wesigaba kunye nomgca omnye ongathathi cala, i-RCBO ayizukusebenza. Oku kuthetha ukuba ayizukubonelela ngokhuseleko kule meko. Ke ngoko, abasebenzisi kufuneka baqaphele lo mda kwaye bathathe amanyathelo ongezelelweyo okunciphisa umngcipheko weengozi ezinjalo.

Elinye icebiso ekufuneka liqwalaselwe kukufakelwa kwesekethe ngasemva kwendawo yokufaka i-RCBO. Kubalulekile ukuba isethe ifakelwe kakuhle ukusuka emhlabeni. Ukuba ukufakwa kwesethe ukuya emhlabeni kunciphile kwaye umsinga wokuvuza udlula ixabiso elithile, ngesiqhelo malunga ne-15mA, i-RCBO iya kusebenza kwaye inqumle umbane. Oku kugxininisa ukubaluleka kokugcina ukufakwa kwesethe kulungile ukusuka emhlabeni ukuthintela iimpazamo nokuqinisekisa ukusetyenziswa kombane ngokufanelekileyo. Ukufakwa kwesethe kufuneka kuhlolwe kwaye kugcinwe rhoqo ukuze kuthintelwe naziphi na iingozi ezinokubakho.

Xa igridi yamandla e-low-voltage isebenzisa ukhuseleko oluhambelanayo, kubalulekile ukusebenzisa i-RCBO ebambezelekileyo kukhuseleko oluphezulu. Ixesha lokuqhekeka kohlobo lokulibaziseka lwe-RCBO kufuneka libe lide kunexesha lokusebenza kwesithinteli esisezantsi, ngokubanzi imizuzwana eyi-0.1 ukuya kweyi-0.2. Olu khuseleko luqinisekisa indlela ebanzi nedibeneyo yokukhusela ngaphakathi kwigridi. Ngokulandela esi sikhokelo, unokunciphisa iingozi ezinokubakho kunye nokuphucula ukhuseleko olupheleleyo lwenkqubo yakho yombane.

Ngamafutshane, nangona ii-RCBO zibalulekile ekukhuseleni ukhuseleko lomntu kunye nokubeka esweni ukugquma komhlaba kwiinkqubo okanye izixhobo ezine-voltage ephantsi, kubalulekile ukuqonda imida yazo kunye nokuthatha amanyathelo okhuseleko afunekayo. Abasebenzisi kufuneka bagxile ekuthinteleni nasekusebenziseni amanyathelo obuchwephesha okhuseleko ahlukeneyo ukuqinisekisa ukusetyenziswa kombane ngokukhuselekileyo. Kuphela ngokulawula ngononophelo ukusetyenziswa kombane, ukugcina ukugquma okuhle, kunye nokusebenzisa amanyathelo okhuseleko alinganisiweyo apho sinokufikelela kwisiqinisekiso esisisiseko sokusetyenziswa kombane ngokukhuselekileyo.
