Ungakhetha kanjani i-MCCB?

I-Plastic shell circuit breaker (i-plastic shell air insulated circuit breaker) isetshenziswa kabanzi embonini yokusabalalisa i-low-voltage, esetshenziselwa ukusika noma ukuhlukanisa uhla olujwayelekile nolulinganiselwe lwephutha lamanje, ukuqinisekisa ukuphepha kwemigqa nemishini.Ngaphezu kwalokho, ngokwezidingo ze-China's "Temporary Power Safety Technical Specification", i-breaker yesikhashana yamandla esizeni sokwakha kumele ibe igobolondo elisobala, ingakwazi ukuhlukanisa ngokucacile isimo sokuxhumana esiyinhloko, kanye nesekethe yokuhambisana. isigqebhezana kufanele sinanyathiselwe uphawu “AJ” olukhishwe 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 yemoto enomsebenzi wokuvikela ukugcwala. noma i-circuit current isikhathi eside idlula i-current elinganiselwe ye-circuit breaker ukuze ihambe, ngakho-ke yaziwa nangokuthi i-tripping kabili, evame ukusetshenziswa ezenzakalweni ezijwayelekile zokusabalalisa amandla. I-breaker magnetic tripping current, i-hot tripping current, nesikhathi sokukhubeka kuyalungiseka, izikhathi ezisebenza kabanzi, kodwa izindleko ze-circuit breaker ziphezulu.Ngaphezu kwezinhlobo ezintathu ezingenhla zemishini yokukhubeka, ngaphezu kwalokho, kunesekhethi. i-breaker esetshenziselwa ngokukhethekile ukuvikelwa kwesekethe 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.
