Umehluko phakathi kwe-AC MCB ne-DC MCB

Umehluko phakathi kwe-I-AC miniature circuit breaker(MCB) kanye ne-I-DC miniature circuit breaker(MCB) kuyinto ebalulekile ekuvikelweni kwesekethe. Ukuqonda lokhu kungafani kubalulekile ekukhetheni i-circuit breaker efanele izidingo zakho ezithile. NjengomholiUmkhiqizi we-MCB, sizibophezele ekukunikezeni ulwazi oludingayo ukuze wenze izinqumo ezinolwazi.

Okokuqala, ake sethule amasekethe afanele alezi zinhlobo ezimbili zama-miniature circuit breaker. Ama-AC miniature circuit breaker aklanyelwe ukusetshenziswa kumasekethe ashintshanayo (AC), kuyilapho ama-DC miniature circuit breaker elungele kakhulu amasekethe aqondile (DC). Lokhu kungenxa yokuthi kunomehluko omkhulu endleleni yokugeleza kwamanje kanye nokushintsha kwamandla kagesi kumasekethe e-AC ne-DC. Ngakho-ke, izinhlobo ezahlukene zama-circuit breaker kudingeka zakhiwe futhi zikhiqizwe ngqo uhlobo ngalunye lwesekethe.

Njengoba siqhubeka nengxoxo yokuthi la ma-MCB asebenza kanjani, ama-AC circuit breaker asebenzisa i-magnetic trigger ukuguqula ugesi ogeleza nge-coil ube yinsimu yamagnetic. Le nsimu yamagnetic ibe isisunduza i-iron core ukuze iqalise ukushintsha, iphule ugesi ngempumelelo. Ngokuphambene nalokho, ama-DC miniature circuit breaker aphula ugesi nge-fuse. Lapho ugesi udlula izinga elithile, i-fuse iyashisa futhi incibilike, iphazamise ugesi.

Ngokuphathelene namazinga okuvikela, ama-DC miniature circuit breaker ngokuvamile ahlinzeka ngezinga eliphezulu lokuvikela kune-AC circuit breaker. Ngokuvamile, ama-DC miniature circuit breaker adinga ukuhlangabezana nezinga lokuvikela le-IP67 ukuqinisekisa ukuvikelwa okusebenzayo othulini nasemanzini. Ama-AC miniature circuit breaker, ngakolunye uhlangothi, ngokuvamile adinga kuphela ukufeza isilinganiso sokuvikela se-IP54. Lawa mazinga okuvikela abalulekile ekunqumeni ukuthembeka nokuphila kwesevisi ye-circuit breaker, okwenza kube yinto ebalulekile okufanele icatshangelwe.

Umehluko womklamo nawo udlala indima ebalulekile ekuhlukaniseni ama-AC nama-DC MCB. Ngenxa yokungazinzi kahle kwe-voltage yokunikezwa kwamandla e-DC, i-DC miniature circuit breaker idinga ukunikezwa kwamandla okuzinzile ukuze kuqinisekiswe ukusebenza kwayo okuvamile. Ngaphezu kwalokho, ama-DC MCB adinga ukubonisa ukuzinza okungcono kokushisa nokuqina ukuze kugwenywe noma yikuphi ukwehluleka ohlelweni lonke. Lokhu kugcizelela ukubaluleka kokukhetha ama-MCB aklanyelwe ngqo amasekethe e-DC, njengoba eklanyelwe ukumelana nezinselele ezihlukile ezilethwa izinhlelo zamandla e-DC.

Ngamafuphi, umehluko omkhulu phakathi kwama-AC miniature circuit breakers nama-DC miniature circuit breakers usesikethini esisebenzayo, isimiso sokusebenza, izinga lokuvikela kanye nomklamo. Uma ukhetha phakathi kwalezi zinhlobo ezimbili zama-MCB, izimo ezithile zokusetshenziswa kanye nezidingo zesistimu kagesi kumele zicatshangelwe. Njengomkhiqizi we-MCB odumile, singakusiza ukhethe i-circuit breaker efanelana kahle nezidingo zakho, siqinisekise ukuvikelwa kwesekethe okuhle kakhulu kanye nokuthula kwengqondo.
