Umehluko phakathi kwezinhlobo ze-elekthronikhi neze-electromagnetic ku-RCBO

Ama-circuit breaker asebenza ngogesi osele (I-RCBO) ziyisici esibalulekile ekuqinisekiseni ukuphepha kwezinhlelo zikagesi. Ngokusho kokuhlukaniswa kwama-trippers, i-RCBO ingahlukaniswa ngohlobo lwe-electromagnetic kanye nohlobo lwe-electronic, ngayinye inezici zayo ezihlukile kanye nezinzuzo. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili kubalulekile ekukhetheni i-RCBO efanele yesicelo esithile.

Umgomo osebenzayo we-RCBO ye-electromagnetic ukusebenzisa isignali etholwe yi-transformer ukushayela ngqo ukukhululwa kwesenzo samanje esisele sohlobo oluphezulu lokuzwela, ngaleyo ndlela kubangele ukuthi i-RCBO isebenze. Enye yezinzuzo ezibalulekile zohlobo lwe-electromagnetic ukuthi aludingi amandla asekelayo, aluthintwa yi-voltage yokunikezwa kwamandla, futhi lunokwethenjelwa okuphezulu. Ngaphezu kwalokho, uhlobo lwe-electromagnetic lumelana kakhulu nokuphazamiseka, luqinisekisa ukusebenza okuzinzile ngisho nasezindaweni zikagesi eziyinselele. Kodwa-ke, lolu hlobo lwe-tripper yamanje esele lunesakhiwo esiyinkimbinkimbi futhi ludinga ukucubungula okuphezulu nokunemba kokukhiqiza, okwenza kube nzima ukukhiqiza imikhiqizo enesilinganiselo esiphezulu, enamandla amakhulu.

Ngakolunye uhlangothi, i-RCBO kagesi isebenzisa i-RCBO ngokukhulisa isignali etholwe yi-transformer ngesekethe ye-amplifier, iqalise i-thyristor noma i-conducting transistor switching circuit. Uma kuqhathaniswa nohlobo lwe-electromagnetic, uhlobo lwe-electronic lunokuzwela okuphezulu, ubuchwepheshe bokukhiqiza obulula, futhi lungakhiqiza imikhiqizo emikhulu. Kodwa-ke, enye yezinkinga zohlobo lwe-electronic ukuthi ludinga amandla asekelayo, okungaba yinto okufanele icatshangelwe kwezinye izinhlelo zokusebenza. Ngaphezu kwalokho, izinhlobo ze-electronic zinokuzivikela okuncane ekuphazamisekeni uma kuqhathaniswa nezinhlobo ze-electromagnetic futhi zidinga ukucatshangelwa ngokucophelela ezindaweni ezinokuthi kube nokuphazamiseka kukagesi okungenzeka.

Ngamafuphi, ukukhetha phakathi kwe-RCBO kagesi kanye ne-elekthronikhi kuncike ezidingweni ezithile zesistimu kagesi. Uhlobo lwe-electromagnetic lunokwethenjelwa okunamandla kanye nekhono lokulwa nokuphazamiseka, kanti uhlobo lwe-elekthronikhi lunokuzwela okuphezulu kanye nokukhiqizwa okulula. Ukuqonda lo mehluko kubalulekile ekukhetheni i-RCBO efanele kakhulu ukuqinisekisa ukuphepha kwesistimu yakho kagesi.
