Ma miniature circuit breakers (MCBs) ndi ma molded case circuit breakers (MCCBs) onse ndi zida zofunika pamakina amagetsi omwe amagwiritsidwa ntchito kuteteza pakuchulukirachulukira, mabwalo amfupi, ndi zolakwika zina. Ngakhale kuti cholinga chake ndi chofanana, pali kusiyana pakati pa ziwirizi malinga ndi kuchuluka kwa mphamvu, mawonekedwe opunthwa, komanso kusweka.

Miniature Circuit Breaker (MCB)

A Miniature circuit breaker (MCB)ndi chipangizo chamagetsi chophatikizika chomwe chimagwiritsidwa ntchito kuteteza mabwalo kumayendedwe afupiafupi komanso mochulukira. Amagwiritsidwa ntchito kwambiri pakuyika magetsi m'nyumba zogona komanso zamalonda ndipo amapangidwa kuti aziteteza mabwalo amtundu uliwonse m'malo mwamagetsi onse.

Molded case circuit breaker (MCCB)

A Mlandu Wophwanyidwa Wozungulira (MCCB)ndi chophatikizira chokulirapo, cholimba kwambiri chomwe chimagwiritsidwanso ntchito kuteteza mabwalo kumayendedwe amfupi, olemetsa, ndi zolakwika zina. Ma MCCB adapangidwa kuti azitha kugwiritsa ntchito magetsi okwera komanso mavoti apano pazamalonda, mafakitale ndi nyumba zazikulu.

Kusiyana Kwakukulu Pakati pa MCCB ndi MCB

Kapangidwe:Ma MCB ndi ophatikizika kukula kuposa ma MCCB. MCB imakhala ndi mzere wa bimetallic womwe umapindika pamene magetsi akudutsa malire ena, kuyambitsa MCB ndikutsegula dera. Koma mapangidwe a MCCB ndi ovuta kwambiri. Makina opangira ma electromagnetic amagwiritsidwa ntchito kuyambitsa kuzungulira pomwe mphamvuyo ipitilira malire ena. Kuphatikiza apo, MCCB ili ndi chitetezo champhamvu chamagetsi kuti chitetezere kuzinthu zambiri komanso mabwalo amfupi.

Kuthekera:Ma MCB nthawi zambiri amagwiritsidwa ntchito pochepetsa mavoti apano komanso magetsi m'nyumba zogona komanso zamalonda. Nthawi zambiri mpaka 1000V ndi mavoti pakati pa 0.5A ndi 125A. Ma MCCB adapangidwa kuti azigwiritsidwa ntchito m'mafakitale komanso akuluakulu azamalonda ndipo amatha kuyendetsa mafunde kuyambira 10 amps mpaka 2,500 amps.

Kuthyola Mphamvu:Kuphwanya mphamvu ndi kuchuluka kwa vuto lomwe woyendetsa dera amatha kuyenda popanda kuwononga. Poyerekeza ndi MCB, MCCB ili ndi mphamvu zosweka kwambiri. Ma MCCB amatha kusokoneza mafunde mpaka 100 kA, pomwe ma MCB amatha kusokoneza 10 kA kapena kuchepera. Chifukwa chake, MCCB ndiyoyenera kugwiritsa ntchito mapulogalamu omwe ali ndi mphamvu zambiri.

Makhalidwe Oyenda:Ubwino wa MCCB ndi MCB ndikusintha kwaulendo. The MCCB amalola munthu kusintha kwa ulendo panopa ndi nthawi kuchedwa kwa chitetezo imayenera kachitidwe magetsi ndi zipangizo. Mosiyana ndi izi, ma MCB ali ndi makonda okhazikika aulendo ndipo amapangidwa kuti aziyenda pamtengo waposachedwa.

Mtengo:Ma MCCB amakhala okwera mtengo kuposa ma MCB chifukwa cha kukula kwake, mawonekedwe ogwirira ntchito, ndi zina zambiri. Ma MCCB amakhala ndi mphamvu zapamwamba komanso zosintha zosinthika zaulendo. Ma MCB nthawi zambiri ndi njira yotsika mtengo yotetezera makina ndi zida zazing'ono zamagetsi.

Mapeto

Mwachidule, ma MCCB ndi ma MCB amatenga gawo lofunikira poteteza mabwalo kumayendedwe afupiafupi, odzaza, ndi zolakwika zina zamakina amagetsi. Ngakhale kuti ntchito kapena zolinga za awiriwa n’zofanana, pamakhalabe kusiyana pakugwiritsa ntchito. Ma MCCB ndi oyenererana ndi machitidwe akuluakulu amagetsi omwe ali ndi zofunikira zamakono, pamene ma MCB ndi otsika mtengo komanso oyenerera kuteteza kachitidwe kakang'ono ka magetsi ndi zipangizo. Kudziwa kusiyana kumeneku kudzakuthandizani kusankha choyendetsa dera choyenera pa zosowa zanu zenizeni ndikuwonetsetsa kuti magetsi anu amakhala otetezeka komanso ogwira mtima.
