Isihloko: Yazi Umahluko PhakathiAbaphuli beSekethe abancincikwayeI-Molded Case Circuit Breakers
Izaphuli zesekethe ziyinxalenye ebalulekileyo yenkqubo yombane yesakhiwo.Banceda ukukhusela ikhaya lakho, iofisi okanye ipropathi yorhwebo ekugqithiseni kombane kunye neesekethe ezimfutshane.Izaphuli-mthetho ezibini eziqhele ukusetyenziswa yi-miniature circuit breaker (MCB) kunye necala elibunjiweyo le-breaker circuit (I-MCCB).Nangona zombini zisebenza injongo enye, kukho umahluko phakathi kwazo.Kule bhlog, siza kuphonononga lo mahluko.
1. Ubungakanani kunye nesicelo
Umahluko ophambili phakathiMCBkwayeI-MCCBubukhulu bazo.Njengoko igama libonisa, ii-MCBs zincinci ngobukhulu kwaye zisetyenziswa kwizicelo ezisezantsi ukuya kuthi ga kwi-125 amps.Ngokuqhelekileyo zisetyenziswa kwiindawo zokuhlala kunye nezicelo ezincinci zorhwebo.Ii-MCCBs, kwelinye icala, zikhulu kwaye ziyakwazi ukuphatha imithwalo yangoku ephezulu ukuya kuthi ga kwi-5000 amps.Ngokuqhelekileyo zisetyenziswa kwimizi-mveliso kunye nezicelo zorhwebo ezifuna izixa eziphezulu zamandla.
2. Yomelele kwaye ihlala ixesha elide
I-MCCB yomelele kwaye yomelele ngakumbi kune-MCB.Ziyakwazi ukujongana noxinzelelo olungakumbi lombane kwaye zenzelwe ukujamelana neendawo ezinzima.Ii-MCCBszidla ngokwenziwa ngemathiriyeli eyomeleleyo njengeceramic okanye iplastiki ebunjiweyo kuneIi-MCBs, ezidla ngokwenziwa kwizindlu zeplastiki.Ii-MCBs ziyilelwe ukuba zisetyenziswe kwindawo ezinoburhalarhume obunganeno kwaye akufuneki zibe sesichengeni sezinto ezonakalisa kakhulu okanye ubushushu obugqithisileyo.
3. Indlela yohambo
Zombini ii-MCBs kunyeIi-MCCBsziyilelwe ukuba zikhubeke xa umsinga ungaphaya komda othile.Nangona kunjalo, iindlela abazisebenzisayo ukuhamba zahlukile.I-MCB inendlela yohambo lwemagnethi eshushu.Umatshini usebenzisa umcu we-bimetal otshisayo kwaye ugobe xa umsinga udlula umgubasi, obangela ukuba i-breaker circuit ihambe.I-MCCB inendlela yohambo lwe-elektroniki esebenzisa i-microprocessor ukuhlalutya ukuhamba kwangoku.Nje ukuba i-current idlule umqobo, i-microprocessor ithumela umqondiso kwi-breaker circuit ukuze ihambe.
4. Iindleko
Ii-MCBszixabisa ngaphantsi kuneIi-MCCBs.Oku kungenxa yokuba zilula kuyilo kwaye zenziwe ngezinto ezingabizi kakhulu.Kananjalo azihlali ixesha elide kune-MCCBs kwaye zinomthamo ophantsi wokuthwala wangoku.Ii-MCCBs zibiza kakhulu ngenxa yoyilo oluntsonkothileyo kunye nezinto ezisetyenziswayo, kodwa zomelele kwaye ziyakwazi ukusingatha imithwalo ephezulu yangoku.
5. Isondlo
Ulondolozo olufunekayo kwii-MCBs kunyeIi-MCCBsyahluke kakhulu.I-MCB ilula kuyilo kwaye ayifuni ukugcinwa okuninzi.Kufuneka zijongwe rhoqo ngusombane kwaye zitshintshwe xa zinempazamo.Ii-MCCBs, kwelinye icala, zifuna ukulungiswa okungakumbi, okufana nokuhlolwa rhoqo kweeyunithi zohambo lwe-elektroniki, ezinokuthi ziphelelwe lixesha kwaye zifuna ukutshintshwa.
Isishwankathelo, i-MCB kunyeI-MCCBube nomsebenzi ofanayo, oko kukukhusela inkqubo yombane ekugqithiseni kunye nesiphaluka esifutshane.Noko ke, njengoko sibona, kukho umahluko phakathi kwezi zimbini.Ii-MCBs zincinci, zihlala ixesha elide kwaye zingabizi kakhulu, ngelixaIi-MCCBszomelele, zomelele kwaye ziyabiza.Isicelo kunye neemfuno zangoku zezona zinto ziphambili ekufuneka ziqwalaselwe xa ukhetha phakathi kwezi zimbini.
