DC Moulded Case Circuit Breaker
DC Moulded Case Circuit Breaker (DC MCCB)
Engineering-Qib DC Circuit Court tiv thaiv rau hnub ci PV, Lub Zog Cia, EV Charging, thiab Kev Lag Luam Distribution
Core Engineering Advantage: Vim li cas DC Yuav Tsum Tau Dedicated MCCBs
Direct-tam sim no (DC) cuam tshuam hauv Circuit Court sib txawv los ntawm kev hloov-tam sim no (AC) cuam tshuam. Hauv AC Circuit Court, tam sim no ib txwm hla xoom txhua ib nrab - voj voog, uas pab tua hluav taws xob arc. DC tsis muaj qhov xwm txheej tam sim no xoom- hla taw tes.
Yog tias tus qauv AC Circuit Court breaker raug xa mus rau hauv daim ntawv thov DC, qhov txuas txuas ntxiv yuav tsis tua, ua rau muaj kev puas tsuaj loj heev, vaj tse tsis ua haujlwm, lossis hluav taws kub tsis zoo.
Peb DC MCCBs muaj lub hom phiaj -engineered internal architecture:
Magnetic Blowout Structures:Siv cov hlau nplaum ruaj khov lossis cov hlau nplaum tshwj xeeb los yuam kom DC arc deb ntawm cov neeg sib cuag.
Optimized Arc Chutes:Ntau- phaj splitters lengthen, txias, thiab sai faib cov arc kem kom paub meej tias tag nrho extinction nyob rau hauv lub milliseconds.
Tested DC Breaking Peev Xwm:Muaj ntawv pov thawj raws li IEC/EN 60947-2 rau kev hloov pauv tam sim no, ua kom ntseeg tau tias muaj kev ua txhaum cai ntawm kev ua haujlwm voltages.
