Semugadziri wemagetsi ane hunyanzvi ane ruzivo rwemakore makumi maviri muindasitiri, YUANKY inopa DC S7 SeriesSolar DC Miniature Circuit Breaker(MCB), mhinduro inoshanda zvakanyanya yakagadzirirwa dziviriro yeDC circuit uye isolation, yakagadzirirwa kuiswa kwezuva ne photovoltaic (PV). Inowanikwa mu 1P kusvika 4P configurations, inotsigira rated voltages kubva kuDC250V kusvika 1000V, rated current kubva ku6A kusvika 50A, uye C-type tripping characteristics (7In-15In). Inopa rated 6kA rated breaking capacity uye 15kA limited short-circuit breaking capacity pa250VDC, ine ultra-fast response time ≤4ms. Dhizaini yayo itsva isina polarized inyaya huru, inobvisa polarity distinction panguva ye wiring, ichichengetedza zvakanyanya nguva yekuisa uye ichidzivirira zvikanganiso zve wiring.

Iyi DC MCB inoshanda nenzira mbiri dzekudzivirira zvikanganiso zveDC system. Kuti idzivirire overload, bimetallic strip yakavakirwa mukati inokotama nekupisa kuti itange kudonha, ichicheka circuit zvakanaka pasi pekuwedzerwa kwenguva refu kudzivirira kukuvara kwekupisa kwemidziyo. Kana paine short-circuit zvikanganiso, high-sensitivity electromagnetic release inoshanda ipapo ipapo, ichikanganisa fault current mukati me ≤4ms kudzivirira njodzi kubva kuDC arcs. Yakashongedzerwa nehunyanzvi hweDC arc extinguishing system, inogadzirisa dambudziko rekutsakatika kwearc muDC circuits dzisina nzvimbo yekuyambuka, zvichiita kuti pave nekuputsika kwakachengeteka uye kwakavimbika. Dhizaini yeDIN rail mounting inobvumira kuiswa kuri nyore uye nekukurumidza mumakabati ekugovera akajairwa.

Ichinyatsoenderana nezvinodiwa zvepasi rose zveIEC 60947-1/2, chigadzirwa ichi chine chitupa cheCE uye mishumo yebvunzo yeCB yakapihwa neSEMKO, ichizadzisa zvinodiwa zvekupinda mumusika wepasi rose. Inoshanda zvakanaka mu -5℃ kusvika +60℃, ichichinjika mumamiriro akasiyana-siyana ekushanda akaomarara. Inoshandiswa zvakanyanya mu grid-tied/off-grid PV systems, mabhatiri ekuchengetedza simba, DC distribution panels, telecom base stations, michina mitsva yesimba uye maindasitiri DC control circuits, isarudzo yakanaka kune vanoisa maPV, vanobatanidza masisitimu uye makontrakita emagetsi pasi rese. Ichitsigirwa nekudzora kwakasimba kwemhando uye sevhisi yakazara yekushambadzira uye mushure mekutengesa, YUANKY DC MCB inopa dziviriro yakavimbika uye inogara kwenguva refu kune masisitimu emagetsi eDC pasi rese.
