Zotsekereza magetsi zimapangidwa m'njira zosiyanasiyana, kuyambira zipangizo zomwe zimateteza magetsi otsika kapena zipangizo zapakhomo, mpaka zida zosinthira magetsi zomwe zimapangidwa kuti ziteteze magetsi amphamvu omwe amadyetsa mzinda wonse.
Liperimapanga Miniature circuit breaker (MCB) - mphamvu yamagetsi yofika pa 63 A, yomwe nthawi zambiri imagwiritsidwa ntchito powunikira m'nyumba, m'mabizinesi, komanso m'mafakitale.
Ma MCB nthawi zambiri sawonongeka akakhala ndi mphamvu yochulukirapo kotero amatha kugwiritsidwanso ntchito. Komanso ndi osavuta kugwiritsa ntchito, zomwe zimapangitsa kuti zikhale zosavuta 'kutsegula/kuzima' kuti magetsi azigwira ntchito ndipo popeza kondakitala ali mkati mwa bokosi la pulasitiki, ndi otetezeka kugwiritsa ntchito ndikugwiritsa ntchito.
MCB ili ndimakhalidwe atatu ofunikira, ma Ampere, ma Kilo Ampere ndi Tripping Curve
Kuchuluka kwa Mphamvu - Ampere (A)
Kuchuluka kwa magetsi kumachitika pamene zipangizo zambiri zimayikidwa pa dera limodzi ndipo zimakoka magetsi ambiri kuposa omwe dera ndi chingwe zimapangidwira. Izi zitha kuchitika kukhitchini, mwachitsanzo pamene ketulo, chotsukira mbale, chitofu chamagetsi, microwave ndi blender zonse zikugwiritsidwa ntchito nthawi imodzi. MCB pa derali imadula magetsi motero imaletsa kutentha kwambiri ndi moto mu chingwe ndi malo olumikizira magetsi.
Miyezo ina:
6 Amp- mabwalo owunikira wamba
10 Amp- mabwalo akuluakulu owunikira
Ma Amp 16 ndi Ma Amp 20- Zotenthetsera ndi zotenthetsera madzi
32 Amp- Mphete Yomaliza. Mawu aukadaulo a magetsi anu kapena soketi. Mwachitsanzo, nyumba yokhala ndi zipinda ziwiri zogona ikhoza kukhala ndi magetsi awiri a 32A kuti ilekanitse soketi zapamwamba ndi zapansi. Nyumba zazikulu zimatha kukhala ndi magetsi a 32 A angapo.
40 Amp- Maphikidwe / malo ophikira magetsi / shawa yaying'ono
50 Amp- Mashawa amagetsi a 10kw / Mabafa otentha.
63 Amp- nyumba yonse
Ma Liper Breakers amaphimba kuyambira 1A mpaka 63A
Kuyeza kwa Dera Lalifupi - Kilo Amperes (kA)
Short Circuit ndi zotsatira za vuto kwinakwake mu circuit yamagetsi kapena chipangizo chamagetsi ndipo ndi choopsa kwambiri kuposa overload.
Ma MCB omwe amagwiritsidwa ntchito mukukhazikitsa kwapakhomonthawi zambiri amawerengedwa kuti6kAkapena ma amperage 6000. Ubale pakati pa magetsi abwinobwino (240V) ndi mphamvu yamagetsi yamagetsi yamagetsi wamba umatanthauza kuti mphamvu yamagetsi yochulukirapo yomwe imayambitsidwa ndi short circuit siyenera kupitirira ma amperage 6000. Komabe, muzochitika zamalonda ndi zamafakitale, mukamagwiritsa ntchito 415V ndi makina akuluakulu, ndikofunikira kugwiritsa ntchito10kAMa MCB ovoteledwa.
Mzere Wokhotakhota
'Tripping Curve' ya MCB imalola kuti mphamvu ziwonjezeke padziko lenileni ndipo nthawi zina zimakhala zofunikira kwambiri. Mwachitsanzo, m'malo ogulitsira alendo, makina akuluakulu nthawi zambiri amafunika mphamvu yoyambira yoposa mphamvu yawo yanthawi zonse kuti athetse vuto la injini zazikulu. Kuthamanga kwakanthawi kochepa kumeneku kumatenga masekondi ochepa, kumaloledwa ndi MCB chifukwa ndi kotetezeka munthawi yochepa kwambiri.
PaliMitundu itatu Yokhotakhotazomwe zimalola kukwera kwa magetsi m'malo osiyanasiyana amagetsi:
Ma MCB a Mtundu Bamagwiritsidwa ntchito muchitetezo cha dera lapakhomokomwe kulibe chifukwa chomveka chololeza kukwera kwa magetsi. Kukwera kwakukulu kulikonse m'nyumba kungakhale chifukwa cha vuto, kotero kuchuluka kwa magetsi ochulukirapo omwe amaloledwa ndi kochepa.
Ma MCB a Mtundu CMaulendo apakati pa 5 ndi 10 a mphamvu yamagetsi yodzaza katundu ndipo amagwiritsidwa ntchito mumalo amalonda ndi mafakitale opepukazomwe zingakhale ndi ma circuit akuluakulu owunikira kuwala kwa fluorescent, ma transformer ndi zida za IT monga ma seva, ma PC ndi ma printers.
Ma MCB a Mtundu Damagwiritsidwa ntchito mumalo ogwirira ntchito zamafakitale olemeramonga mafakitale ogwiritsa ntchito ma winding motors akuluakulu, ma X-ray machines kapena ma compressor.
Mitundu yonse itatu ya ma MCB imapereka chitetezo cha kugwa mkati mwa gawo limodzi mwa magawo khumi a sekondi. Izi zikutanthauza kuti, akapitirira kuchuluka ndi nthawi yochulukirapo, MCB imagwa mkati mwa masekondi 0.1.
Chifukwa chake, Liper nthawi zonse amakwaniritsa zosowa zanu zonse.
