Mlandu Wophwanyika Wowonongeka (MCCB) Basic Guide

Zowonongeka Zozungulira Zozungulira(MCCB) ndi gawo lofunikira pamakina aliwonse amagetsi, omwe amapereka mochulukira komanso chitetezo chachifupi. Zipangizozi nthawi zambiri zimayikidwa pagawo lalikulu lamagetsi kuti zilole kuti makina azimitsidwa mosavuta pakafunika kutero. Ma MCCB amabwera mosiyanasiyana komanso mosiyanasiyana ndipo amagwira ntchito yofunika kwambiri powonetsetsa kuti magetsi ndi otetezeka komanso odalirika.

Zigawo ndi Zina

Chojambulira chophatikizika chokhazikika chimakhala ndi zigawo zingapo zofunika, kuphatikiza gawo laulendo, makina ogwiritsira ntchito ndi zolumikizirana. Gawo laulendo limayang'anira kuzindikira zochulukira komanso mabwalo amfupi, pomwe makina ogwiritsira ntchito amalola kugwiritsa ntchito pamanja komanso kuwongolera kutali. Ma Contacts amapangidwa kuti azitsegula ndi kutseka mabwalo ngati pakufunika, kupereka chitetezo chofunikira.

Mfundo yogwirira ntchito ya pulasitiki kesi circuit breaker
MCCB imagwira ntchito powunika momwe magetsi akuyendera. Pamene kuchulukira kapena dera lalifupi lizindikirika, gawo laulendo limayambitsa olumikizana kuti atseguke, ndikusokoneza kuyendetsa bwino kwa magetsi ndikuletsa kuwonongeka kwa dongosolo. Kuyankha mwachangu kumeneku ndikofunikira pakuteteza zida zamagetsi ndi zida zolumikizidwa.

Mitundu ndi ubwino
Ma MCCB amapezeka m'mitundu yosiyanasiyana, iliyonse yopangidwa kuti ikwaniritse zofunikira zenizeni. Mphamvu yamagetsi yamagetsi yamagetsi ophatikizika ndi 1000V, yomwe ili yoyenera kusinthana pafupipafupi ndi mota kuyambira mabwalo a AC 50Hz. Amavotera ma voltages ogwiritsira ntchito mpaka 690V ndi ma voteji apano mpaka 800 ACSDM1-800 (popanda chitetezo chamoto). Mogwirizana ndi miyezo monga IEC60947-1, IEC60947-2, IEC60947-4 ndi IEC60947-5-1, MCCB ndi njira yosunthika komanso yodalirika yogwiritsira ntchito zosiyanasiyana.

Ubwino wogwiritsa ntchito ma MCCB pamakina amagetsi ndi ambiri. Amapereka chitetezo chofunikira ku zolakwika zamagetsi, kuonetsetsa chitetezo cha ogwira ntchito ndi zipangizo. Kuphatikiza apo, ma MCCB ndi osavuta kukhazikitsa ndikuwongolera, zomwe zimathandizira kukonza magwiridwe antchito amagetsi.

Mwachidule, zomangira ma circuit breakers ndizofunikira kwambiri kuti magetsi azigwira bwino ntchito. Kumvetsetsa zigawo zake, ntchito zake, ndi mfundo zake zogwirira ntchito ndikofunikira kuti mupange zisankho zodziwika bwino pakusankhidwa kwake ndi kukhazikitsa. Ndi kuthekera kwawo kosiyanasiyana komanso chitetezo, ma MCCB ndiye mwala wapangodya wa uinjiniya wamakono wamagetsi ndipo amatenga gawo lalikulu pakuteteza zida zofunika kwambiri.
