Isingeniso ku-Molded Case Circuit Breaker (MCCB)

Isingeniso se-I-Molded Case Circuit Breaker (I-MCCB) kushintshe indlela esivikela ngayo amasekethe nemishini. Le divayisi entsha iklanyelwe ukuvala ngokuzenzakalela ukugeleza kwamanje uma kudlula ukulungiselelwa kohambo, ngaleyo ndlela ihlinzeka ngokuvikelwa okuyisisekelo ekuthwaleni ngokweqile, i-short circuit kanye nephutha lomhlabathi. I-MCCB igcinwe ekhasethini lepulasitiki futhi isebenzisa ama-insulators epulasitiki ukuhlukanisa ama-conductor nezingxenye zensimbi ezisekelwe phansi. Ngezici zayo eziningi nezinketho, i-MCCB iyisisombululo esiguquguqukayo nesithembekile sezinhlelo zokusebenza ezahlukahlukene.

Ama-MCCB avame ukuqukatha iyunithi yohambo olusebenzisa ugesi ...

Esinye sezici eziyinhloko ze-MCCB ukwakhiwa kwayo okuvaliwe ngaphakathi kwendlu yepulasitiki. Lo mklamo uqinisekisa ukuthi zonke izingxenye ze-molded case circuit breaker zivikelwe ngempumelelo ezicini zemvelo, okuthuthukisa ukuthembeka nokuphila kwesevisi yemishini. Ngaphezu kwalokho, oxhumana nabo abasizayo, ukukhishwa kwe-undervoltage kanye nokukhishwa kwe-shunt ngokuyinhloko kuyi-modular futhi kungenziwa ngezifiso kalula futhi kuhlanganiswe nemisebenzi eyengeziwe njengoba kudingeka. Nakuba isakhiwo esiqinile se-molded case circuit breaker sinciphisa ukuseviswa, sinikeza ukusebenziseka kalula ngesandla kanye nezinketho ezinkulu zokushintsha ugesi ukuze kuhlangatshezwane nezidingo ezahlukahlukene zabasebenzisi ezinhlelweni ezahlukene.

I-MCCB iphinde inikeze ukukhetha kokukhishwa kwe-electronic overcurrent, okuhlukaniswe ngezinhlobo ezimbili: Isigaba A kanye neSigaba B. Isigaba B MCCB inikeza izici zokuvikela ezisezingeni ezintathu ezithuthukisiwe, okwenza ifaneleke ezinhlelweni zokusebenza ezinezidingo zokuthembeka okuphezulu kanye nokusebenza. Ngakolunye uhlangothi, i-Class A MCCB ene-thermal magnetic tripper inesabelo semakethe esiphezulu ngenxa yokusebenza kwayo kahle kwezindleko. Zombili izinhlobo ze-MCCB zifaneleka kakhulu ezinhlotsheni ezahlukahlukene zezimboni nezentengiselwano, zihlinzeka ngokuvikelwa kwamaphutha kagesi okudingekayo kanye nokuqinisekisa ukuphepha nokuthembeka kwezinhlelo zikagesi.

Ngamafuphi, ama-plastic case circuit breakers (ama-MCCB) ayizingxenye ezibalulekile ezinhlelweni zikagesi zesimanje, ahlinzeka ngezici zokuvikela ezithuthukisiwe kanye nokusebenza okuthembekile. Njengoba inezindlu zayo zepulasitiki ezivaliwe, izingxenye ze-modular ezingenziwa ngokwezifiso kanye nezinketho eziningi zeyunithi yokuhamba, i-MCCB ilungele amandla ahlukahlukene okulayisha kanye nezinhlelo zokusebenza. Kungakhathaliseki ukuthi ivikela amasekethe amagatsha noma ihlinzeka ngokuvikelwa okuthuthukisiwe kwezinga lesi-3, ama-MCCB angamathuluzi ahlukahlukene futhi abalulekile okuqinisekisa ukuphepha nokuthembeka kwezinhlelo zikagesi.
