1. Izinto ezithonya izici zokufanisa umehluko wezinga
Ohlelweni lwe-Xiushan, ngenxa yezidingo ezihlukene zobuchwepheshe zezikhungo zokuphakela amandla ekukhetheni umthamo webhethri wesiteshi ngasinye, imodi yokuphakela amandla yesikrini se-DC kanye nesikrini sokulinganisa nokuvikela sokulawula, imodi yokuxhuma nokubaluleka kokuvikela. , izikhundla zokusabalalisa zihlukile ngokuhambisanayo, okuholela ekukhethweni kwezintambo nama-conductor.Indawo ye-cross-sectional kanye nobude buhlukile, futhi umehluko walezi zici uzodala ukuthi inani lokumelana ne-loop lishintshe, futhi ukuguqulwa kwevelu yokumelana nakho kuzobangela ukuba inani lamanje le-short-circuit lishintshe, okubangela ukuthi i-short-circuit current esiteshini ngasinye ukuze sihluke.Ngakho-ke, umklamo wohlelo lokudidiyela umehluko wezinga le-breaker circuit yesistimu ye-DC yesiteshi esincane, ngenxa yezinguquko ezinkulu zezinto ezibalwe ngenhla, ayikaxazululwa kahle kakhulu.
2. Izingozi ezikhona ezifihliwe
Ukuze kuhlangatshezwane nezidingo ezikhethiwe zokuxhumanisa umehluko weleveli, i-circuit breaker yeleveli ephezulu ayisebenzi kahle, noma noma ngabe ukungasebenzi kahle kwezinga eliphezulu, ngeke kubangele ingozi ukuthi isakazeke.Ezinsukwini zanamuhla, isinqamuli sesekhethi nokulinganisa nokuvikela ukuvikela esikrinini sesiphakeli (noma isikrini sokusabalalisa amandla) ezinhlelweni eziningi ze-DC I-circuit breaker esikrinini isebenzisa imodi yokuphakelwa kwamandla okukodwa kuya kokukodwa.Inkinga ebangelwa yile ndlela ukuthi kukhona izintambo ezimbili phakathi kwepheya ngalinye lama-circuit breaker.Amamitha ambalwa, amakhulu amamitha, lezi zintambo eziningi nezinde zihlanganiswe ndawonye, futhi ngemva kweminyaka yokusebenza nokusetshenziswa, izinkinga eziyinkimbinkimbi neziyaluyalu zizokwenzeka, njengokuthi: ukuxhumana okuxekethile phakathi kwezintambo kanye ne-breaker circuit;ukufakwa kwezintambo kwehlile;umonakalo ngengozi, Bite;izintambo ezihlanganisiwe zifihla izingozi ezifana ne-multi-circuit short circuit noma i-arc discharge fire, okuzodala ingozi enkulu efihliwe yokulahlekelwa okuphelele kwamandla esikrinini sokulinganisa nokulawula.
3. Ukubaluleka kwezici zokuqhathanisa umehluko wezinga
Ukuthi amazinga aphezulu naphansi weama-soosan breakerbreakersingafinyelela ukuxhumanisa komehluko weleveli kuncike enanini le-short-circuit current egeleza ku-loop kanye nomehluko wesikhathi sesenzo sezinqamuli zesekethe ezingaphezulu neziphansi.Ukuqaliswa okuyisisekelo ukuthuthukisa ukusebenza okukhawulelwe kwamanje kanye nesivinini sokwephulwa kwezinqamuli zesekethe ze-2A~6A zesikrini sokulinganisa nokuvikela sokulawula, futhi okwesibili ukukhulisa umkhawulo wokukhululwa kwesekethe esifushane we-DC circuit breaker emandleni. isikrini sokusabalalisa kanye nesikrini sokuphakelayo.Ukuze ubambezele isenzo.Kuphela lapho inani lamanje lesekethe elifushane kusekethe liphansi kunevelu esheshayo ye-breaker circuit yezinga eliphezulu, noma i-breaker circuit yezinga eliphansi iphuka ngaphambi kwe-high-level breaker nakuba inani elisheshayo lesekhethi yezinga eliphezulu i-breaker ifinyelelwa, ingabe umehluko wezinga lokuxhumanisa phakathi kwama-breaker circuit ungenzeka.Ngakho-ke, ukuze kuzuzwe ukuhlanganiswa komehluko wezinga, enye indlela ukufeza umehluko ngesikhathi sokusebenza kwama-breaker circuit angaphezulu naphansi, kanti enye indlela ukunciphisa inani lamanje lesifunda esifushane.I-DC ekhawula i-circuit breaker enenani elincane elingashintshi inomphumela obalulekile ekwehliseni inani lesifunda esifushane.Ngakho-ke, ukusebenza okukhawulayo kwamanje kwesiphazamisi esincane sesigaba sokugcina kuyisici esibalulekile sokuhlanganisa okukhethiwe kwalo lonke uhlelo lwe-DC.
