dziwitsani:
Mu engineering yamagetsi,kuumbidwa nkhani circuit breakers (MCCBs) ndi zigawo zofunika kwambiri poteteza machitidwe amagetsi kuti asachulukidwe, maulendo afupikitsa ndi njira zina zolephera.MCCBsamagwiritsidwa ntchito m'njira zosiyanasiyana m'malo okhala, malonda ndi mafakitale kuti awonetsetse kuti magetsi akuyenda bwino komanso otetezeka.M'nkhaniyi, tiwona momwe ma MCCB amagwiritsira ntchito, mawonekedwe ake, ndi malingaliro.
Kugwiritsa ntchito kwakuumbidwa mlandu circuit breaker:
MCCBsamagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo:
1. Ntchito zamafakitale: Ma MCCB amagwiritsidwa ntchito nthawi zambiri m'mafakitale kuti ateteze makina amagetsi kuzinthu zambiri, mabwalo amfupi, ndi zolakwika zina.Ntchitozi zikuphatikiza kupanga, mafuta ndi gasi, migodi ndi malo ena ogulitsa.
2. Ntchito zamalonda: Zowonongeka zowonongeka zimagwiritsidwa ntchito pazinthu zamalonda, monga masitolo, mahotela, nyumba zamaofesi, ndi zina zotero, kuti zitsimikizire kuti magetsi akuyenda bwino komanso otetezeka.
3. Ntchito zogona: Zowonongeka zomangika zimagwiritsidwa ntchito m'malo okhala kuti zitsimikizire chitetezo cha omwe ali m'nyumba.Imayikidwa m'mabokosi ogawa kuti ateteze mabwalo ku zolakwika zamagetsi.
Mawonekedwe a ma mold case circuit breakers:
1. Mawonekedwe apano: Mawonekedwe apano a ma amperes owumbidwa amasiyana, kuyambira ma amperes angapo mpaka masauzande angapo.Izi zimathandiza kuti zigwiritsidwe ntchito zosiyanasiyana.
2. Maonekedwe a Tripping: The molded case circuit breaker ili ndi khalidwe lodumpha, lomwe limatsimikizira kuti dera likuyenda pakagwa vuto lamagetsi kuti lisawonongeke.Makhalidwe a ulendowo akhoza kukhala otentha kapena maginito.
3. Kuthamanga kwapamwamba kwambiri: Chophwanyira chophwanyidwa chamilandu chimakhala ndi mphamvu yosweka kwambiri ndipo chimatha kupirira vuto lalikulu lamakono popanda kuwonongeka.Izi zimatsimikizira kuti dera limatetezedwa kuti lisawonongeke.
4. Kusankha: Mlandu wopangidwa ndi chigawo chophwanyidwa umapereka kusankha kwa magetsi, ndiko kuti, kokha kachipangizo kamene kamapangidwira pafupi ndi maulendo olakwika, pamene maulendo ena mumagetsi sakukhudzidwa.
Njira zodzitetezera posankha ma frequency circuit breakers:
1. Mawonekedwe amakono: Posankha chopukutira chamagetsi chopangidwa, mphamvu yamagetsi yamagetsi iyenera kutsimikiziridwa kuonetsetsa kuti chopondera chophwanyika chikhoza kupirira pakali pano popanda kugwedezeka.
2. Mtundu wa kulephera: Mtundu wa kulephera komwe MCCB idapangidwa kuti itetezedwe ndikofunikira posankha MCCB.Mwachitsanzo, ma MCCB ena amapangidwa kuti ateteze ku kulephera kwa matenthedwe, pomwe ena adapangidwa kuti ateteze ku kulephera kwa maginito.
3. Kutentha kozungulira: Kutentha kozungulira kwa chilengedwe komwe malo ophwanyira ozungulira amakhala nawonso ndizofunikira kwambiri.MCCB ili ndi matenthedwe ndipo mwina singagwire bwino ntchito ngati kutentha kwapakati kupitilira muyezo wa MCCB.
Mwachidule: MCCB ndi gawo lofunika kwambiri pamagetsi chifukwa limapereka chitetezo ku zovuta zamagetsi.Ili ndi mafunde osiyanasiyana ovotera, mawonekedwe odumphira komanso kusweka, kotero ndiyoyenera kugwiritsa ntchito mosiyanasiyana.Posankha MCCB, mlingo wamakono, mtundu wolakwika, ndi kutentha kozungulira ziyenera kuganiziridwa kuti zitsimikizidwe kuti zikugwira ntchito moyenera.
