Ungakhetha kanjani i-MCCB?

I-Plastic shell circuit breaker (i-plastic shell air insulated circuit breaker) isetshenziswa kabanzi embonini yokusabalalisa i-voltage ephansi, esetshenziselwa ukusika noma ukuhlukanisa uhla olujwayelekile futhi olulinganiselwe lwephutha lamanje, ukuqinisekisa ukuphepha kwemigqa nemishini.Ngaphezu kwalokho, ngokwezidingo ze-China's "Temporary Power Safety Technical Specification", isihlukanisi samandla esikhashana esizeni sokwakha kumele sibe negobolondo elisobala, singakwazi ukuhlukanisa ngokucacile isimo sokuxhumana esiyinhloko, futhi isinqamuli sesekethe sokuthobelana kufanele sinanyathiselwe uphawu "AJ" ekhishwe umnyango wezokuphepha ofanele.

I-QF ivamise ukusetshenziselwa ukumela i-circuit breaker, futhi imidwebo yangaphandle ngokuvamile ibizwa ngokuthi i-MCCB.Izindlela ezijwayelekile zokuthiphuca igobolondo lepulasitiki lepulasitiki ukukhubeka okukodwa kazibuthe, ukukhubeka okushisayo kazibuthe (ukukhubeka kabili), ukukhubeka nge-elekthronikhi.Ukugibela kazibuthe okukodwa kusho ukuthi isifunda i-breaker ihamba kuphela lapho isifunda sinokuhluleka kwesekethe emfushane, futhi ngokuvamile sisebenzisa le swishi ku-loop ye-heater noma isekethe ye-motor enomsebenzi wokuvikela ukulayisha ngokweqile.I-thermal tripping ukwehluleka kwesekethe emfushane noma i-circuit current isikhathi eside idlula isilinganiso. i-current ye-circuit breaker ukuze ihambe, ngakho-ke kubuye kwaziwe ngokuthi yi-double tripping, evame ukusetshenziswa ezikhathini ezijwayelekile zokusabalalisa amandla.I-Electronic Tripping ubuchwepheshe obuvuthiwe obuvela eminyakeni yamuva nje, nge-electronic tripping circuit breaker magnetic tripping current, hot tripping current, kanye isikhathi sokukhubeka siyalungiseka, izikhathi ezisetshenziswa kabanzi, kodwa izindleko ze-circuit breaker ziphezulu.Ngaphezu kwezinhlobo ezintathu ezingenhla zamadivayisi okukhubeka, ngaphezu kwalokho, kukhona i-circuit breaker esetshenziselwa ngokukhethekile ukuvikela isekethe yemoto.Amandla kazibuthe ayo agibelayo ngokuvamile angaphezulu kwezikhathi eziyi-10 kunowamanje olinganisiwe ukuze ugweme amandla aphezulu lapho injini iqala futhi iqinisekise ukuthi injini iqala kahle futhi i-breaker yesifunda ayinyakazi.

I-Plastic shell circuit breaker inezinhlobonhlobo zezesekeli ezingalengiswa, ezifana ne-remote electric operation switch mechanism, ikhoyili evusa amadlingozi, othintana naye osizayo, ukuthintana ne-alamu, njll.

Lapho ukhetha umshini wokusebenza kagesi, ukunakwa kufanele kukhokhwe kuhlaka olusekelayo lwendlu ye-breaker circuit yamanje, ngoba usayizi wangaphandle we-shell shell frame i-circuit breaker yamanje kanye ne-torque yendlela yokuvala ihlukile.
