Umehluko phakathi kwe-DC mini circuit breaker ne-AC circuit breaker

Umehluko phakathi kwe-DC mini circuit breaker kanyeI-I-I-AC circuit breaker

Ama-DC (Direct Current) ama-circuit breaker amancane kanye nama-circuit breaker e-AC (Alternating Current) kokubili asetshenziselwa ukuvikela amasekhethi kagesi kuma-overcurrents namasekhethi amafushane, kodwa anomehluko othile obalulekile ngenxa yezici ezihlukile zezinhlelo zikagesi ze-DC kanye ne-AC.

I-polarity yamanje:
Umehluko obaluleke kakhulu phakathi kwama-circuit breaker e-DC kanye ne-AC amandla azo okuphatha i-polarity yamanje. Kumjikelezo we-AC, ukugeleza kwamanje kubuyisela emuva isiqondiso ngezikhathi ezithile (ngokuvamile izikhathi ezingu-50 noma ezingu-60 ngomzuzwana, kuye ngefrikhwensi ye-AC).I-I-AC circuit breakersyakhelwe ukuphazamisa ukugeleza kwamanje endaweni yokuwela uziro, lapho i-waveform yamanje idlula uziro. Ngakolunye uhlangothi, ama-circuit breaker e-DC aklanyelwe ukuphatha ukugeleza kwamanje okungaqondile futhi aphazamise ukugeleza kwamanje ezingeni elithile le-voltage.

Ukuphazamiseka kwe-Arc:
Kumasekhethi e-AC, okwamanje ngokwemvelo kweqa uziro phakathi nomjikelezo ngamunye, okusiza ekucimeni ngokwemvelo i-arc eyakhayo lapho isekethe iphazamiseka.I-I-I-AC circuit breakers basebenzise leli phuzu lokuwela iqanda ukuze bacime i-arc, okwenza inqubo yokuphazamiseka ibe lula. Kumasekhethi e-DC, alikho iphuzu lemvelo lokuwela uziro, okwenza ukuphazamiseka kwe-arc kube inselele kakhulu. Ama-circuit breaker e-DC aklanyelwe ukuphatha izinselele ezithile zokuphazamiseka kwe-arc kumasekethe e-DC.

I-Arc Voltage:
I-voltage kubo bonke abathintwayo be-circuit breaker ngesikhathi senqubo yokuphazamiseka kwe-arc ihlukile kumasistimu e-DC kanye ne-AC. Ezinhlelweni ze-AC, i-arc voltage isondela ku-zero endaweni yemvelo yokuwela u-zero, isiza enqubweni yokuphazamiseka. Ezinhlelweni ze-DC, i-arc voltage ihlala iphezulu, okwenza ukuphazamiseka kube nzima kakhulu. Ama-circuit breaker e-DC aklanyelwe ukumelana nokucisha ama-arc voltages aphezulu.

Ukwakha Nokuklama:
Ama-circuit breaker e-AC kanye nama-circuit breaker e-DC akhiwe ngendlela ehlukile ukuze ahlangabezane nezidingo ezithile zezinhlelo zawo. Izindlela zokuphazamiseka kwe-arc, izinto ezisetshenziswayo, nemiklamo yokuxhumana ingahluka phakathi kwama-breaker circuit AC kanye ne-DC.

Izicelo:
I-I-AC circuit breakersasetshenziswa kakhulu ezinhlelweni zokusabalalisa ugesi ezindaweni zokuhlala, ezohwebo, nezimboni, lapho amandla e-AC eyindinganiso. Ngakolunye uhlangothi, ama-DC mini circuit breaker, avame ukusetshenziswa ezinhlelweni zokusabalalisa amandla e-DC, amabhange ebhethri, izinhlelo zamandla avuselelekayo (njengelanga nomoya), kanye nezinhlelo zokusebenza eziyisipesheli zezimboni lapho kusetshenziswa khona amandla aqondile.

Kafushane, umehluko omkhulu phakathi kwe-DC mini circuit breaker kanyeI-I-AC circuit breakerszilele ekhonweni lazo lokuphatha i-polarity yamanje, izici zokuphazamiseka kwe-arc, izidingo ze-voltage, ukwakhiwa, kanye nezinhlelo zokusebenza ngokulandelana kwazo. Kubalulekile ukusebenzisa uhlobo olufanele lwe-circuit breaker olusekelwe ohlelweni oluthile lukagesi ukuze kuqinisekiswe ukuvikelwa okusebenzayo nokusebenza okuphephile.
