Umhlahlandlela Wokukhetha I-Residual Current Circuit Breaker enokusebenza Kwamanje Okufanelekile

Uma kuziwa ekuphepheni kukagesi, ukukhetha i-breaker circuit yamanje eyinsalela ene-current yokusebenza efanele kubalulekile. Ama-circuit breaker amanje, aziwa nangokuthi amadivaysi asalayo (RCD), aklanyelwe ukuvikela engcupheni yokushaqeka kukagesi nomlilo odalwa amaphutha asemhlabeni. Ukukhetha i-RCD efanele yohlelo lwakho lokusebenza kubalulekile ekuqinisekiseni ukuphepha kwabantu nempahla.

Isinyathelo sokuqala ekukhetheni i-circuit breaker yamanje eyinsalela ukucacisa ukusebenza kwamanje okudingwa isistimu yakho kagesi. Lokhu kungenziwa ngokuhlola isamba somthwalo osesekeni futhi kunqunywe umthamo wamanje omkhulu ongavuza phansi. Kubalulekile ukucabangela ukusebenza kwamanje okujwayelekile kanye nanoma yimiphi imisinga yesikhashana engase yenzeke.

Uma ukusebenza kwamanje sekunqunyiwe, uhlobo olufanele lwe-RCD lungakhethwa. Kunezinhlobo ezahlukene zama-RCD atholakalayo, okuhlanganisa Uhlobo AC, Uhlobo A kanye Nohlobo B, uhlobo ngalunye luklanyelwe ukunikeza isivikelo ohlotsheni oluthile lwephutha. Isibonelo, Uhlobo lwe-AC RCDs lufanele izicelo ezijwayelekile, kuyilapho uhlobo A RCD ludizayinelwe ukunikeza ukuvikeleka okwengeziwe kumaza e-DC aphehlayo. Ama-RCD oHlobo lwe-B ahlinzeka ngezinga eliphezulu kakhulu lokuvikela futhi afanele izindawo ezibucayi njengezikhungo zezokwelapha nezikhungo zedatha.

Ngaphezu kokukhetha uhlobo olulungile lwe-RCD, kubalulekile futhi ukucabangela ukuzwela kwedivayisi. Ama-RCD atholakala kumazinga ahlukene okuzwela, ngokuvamile asukela ku-10mA kuya ku-300mA. Ukukhetha izinga elifanele lokuzwela kuncike ezidingweni ezithile zesistimu kagesi kanye nezinga lokuvikela elidingekayo.

Ngaphezu kwalokho, kufanele kuqinisekiswe ukuthi i-RCD ekhethiwe ihambisana namazinga nemithethonqubo efanele yokuphepha. Bheka ama-RCD aqinisekiswe yi-ejensi yokuhlola egunyaziwe futhi ahlangabezane nezidingo ezidingekayo zokusebenza nezokuphepha.

Ngamafuphi, ukukhetha i-breaker circuit evuzayo enamanje esebenzayo kubalulekile ekuqinisekiseni ukuphepha kukagesi. Ngokunquma ngokunembile ukusebenza kwamanje, ukukhetha uhlobo olufanele lwe-RCD nokuzwela, nokuqinisekisa ukuthobela izindinganiso zokuphepha, ungakwazi ukuvimbela ngempumelelo ukushaqeka kanye nezingozi zomlilo ohlelweni lwakho lukagesi.
