Isihloko: Yazi Umahluko PhakathiIiMinimable Circuit BreakerskwayeAbaphuli beeSekethe zeTyala eziBunjiweyo
Iziphuli zesekethe ziyinxalenye ebalulekileyo yenkqubo yombane yesakhiwo. Zinceda ekukhuseleni ikhaya lakho, iofisi okanye ipropathi yorhwebo kwimithwalo yombane emininzi kunye neesekethe ezimfutshane. Iziphuli zesekethe ezimbini ezisetyenziswa kakhulu yi-miniature circuit breaker (I-MCB) kunye nesixhobo sokwaphula isekethe esibunjiweyo (I-MCCBNangona zombini zisebenza injongo enye, kukho umahluko phakathi kwazo. Kule bhlog, siza kuhlola lo mahluko.
1. Ubungakanani kunye nokusetyenziswa
Umahluko ophambili phakathiI-MCBkwayeI-MCCBubukhulu bazo. Njengoko igama lisitsho, ii-MCB zincinci ngobukhulu kwaye zisetyenziswa kwizicelo zamandla aphantsi ukuya kuthi ga kwi-125 amps. Zisetyenziswa rhoqo kwizicelo zokuhlala kunye nezorhwebo ezincinci. Ii-MCCB, kwelinye icala, zinkulu kwaye zinokuphatha imithwalo yamandla aphezulu ukuya kuthi ga kwi-5000 amps. Zisetyenziswa rhoqo kwizicelo zoshishino kunye nezorhwebo ezifuna amandla aphezulu.
2. Yomelele kwaye ihlala ixesha elide
I-MCCB inamandla kwaye ihlala ixesha elide kune-MCB. Ziyakwazi ukumelana noxinzelelo lombane kwaye zenzelwe ukumelana neemeko ezinzima.IiMCCBzihlala zenziwe ngezinto eziqinileyo ezifana ne-ceramic okanye iplastiki ebunjiweyo kuneIi-MCB, ezidla ngokwenziwa ngendlu yeplastiki. Ii-MCB zenzelwe ukusetyenziswa kwiindawo ezingabalulekanga kangako kwaye akufuneki zibekwe kwizinto ezinokutsha kakhulu okanye kumaqondo obushushu agqithisileyo.
3. Indlela yohambo
Zombini ii-MCB kunyeIiMCCBZenzelwe ukukhubeka xa umbane udlula umda othile. Nangona kunjalo, iindlela abazisebenzisayo ukukhubeka zahlukile. I-MCB inendlela yokutshintsha umbane ngemagnethi eshushu. Le ndlela isebenzisa umcu we-bimetal oshushu kwaye ugobe xa umbane udlula umda othile, nto leyo ebangela ukuba i-circuit breaker ikhubeke. I-MCCB inendlela yokutshintsha umbane nge-elektroniki esebenzisa i-microprocessor ukuhlalutya ukuhamba kombane. Nje ukuba umbane udlule umda othile, i-microprocessor ithumela isignali kwi-circuit breaker ukuze ikhubeke.
4. Ixabiso
Ii-MCBngokubanzi zibiza kancinci kuneIiMCCBOku kungenxa yokuba zilula ngoyilo kwaye zenziwe ngezinto ezingabizi kakhulu. Zikwahlala ixesha elide kunee-MCCB kwaye zinomthamo omncinci wokuthwala umbane. Ii-MCCB zibiza kakhulu ngenxa yoyilo lwazo oluntsonkothileyo kunye nezinto ezisetyenzisiweyo, kodwa zihlala ixesha elide kwaye zinokusingatha imithwalo ephezulu yamandla ombane.
5. Ukugcinwa
Ulondolozo olufunekayo kwii-MCB kunyeIiMCCByahlukile kakhulu. I-MCB ilula ngoyilo kwaye ayifuni kulungiswa kakhulu. Kufuneka ihlolwe rhoqo ngumbane kwaye itshintshwe ukuba ineziphene. Ii-MCCB, kwelinye icala, zifuna ukulungiswa okungakumbi, njengokuhlolwa rhoqo kweeyunithi zokuhamba nge-elektroniki, ezinokuphelelwa lixesha ngokuhamba kwexesha kwaye zifune ukutshintshwa.
Ngamafutshane, i-MCB kunyeI-MCCBzinomsebenzi ofanayo, okukhusela inkqubo yombane kwi-overload kunye ne-short circuit. Nangona kunjalo, njengoko sibona, kukho umahluko phakathi kwezi zimbini. Ii-MCB zincinci, zihlala ixesha elide kwaye azibizi kakhulu, ngelixaIiMCCBziqinile, zihlala ixesha elide kwaye zibiza kakhulu. Ukusetyenziswa kunye neemfuno zangoku zezona zinto ziphambili ekufuneka ziqwalaselwe xa ukhetha phakathi kwezi zimbini.
