Zowononga ma circuit zimapangidwa mosiyanasiyana pano, kuchokera ku zida zomwe zimateteza mabwalo ocheperako kapena zida zapakhomo zapanyumba, mpaka ma switchgear opangidwa kuti ateteze mabwalo amphamvu kwambiri omwe amadyetsa mzinda wonse.
Lipereamapanga Miniature circuit breaker (MCB) - yovotera pano mpaka 63 A, yomwe nthawi zambiri imagwiritsidwa ntchito popangira nyumba, zamalonda, zowunikira mafakitale.
Ma MCB nthawi zambiri samawonongeka pakapita nthawi kotero amatha kugwiritsidwanso ntchito. Zimakhalanso zosavuta kuzigwiritsa ntchito, zomwe zimapatsa mwayi woti 'on/off switching' azidzipatula komanso popeza kondakitala amakhala m'bokosi la pulasitiki, amakhala otetezeka kugwiritsa ntchito ndikugwira ntchito.
MCB ili ndimakhalidwe atatu mfundo, Amperes, Kilo Ampere ndi Tripping Curve
Zochulukira Panopa - Amperes (A)
Kuchulukirachulukira kumachitika pamene zida zambiri zimayikidwa pagawo limodzi ndikukoka magetsi ochulukirapo kuposa dera ndi chingwecho zomwe zidapangidwa kuti zizitenga. Izi zikhoza kuchitika kukhitchini, mwachitsanzo pamene ketulo, chotsukira mbale, hob yamagetsi, microwave ndi blender zonse zikugwiritsidwa ntchito nthawi imodzi. The MCB pa dera amadula mphamvu motero kupewa kutenthedwa ndi moto mu chingwe ndi materminal.
Miyezo ina:
6 ampe- mabwalo owunikira okhazikika
10 amp- zozungulira zazikulu zowunikira
16 Amp ndi 20 Amp- Ma heater ndi ma boiler omiza
32 amp- Ring Final. Mawu aumisiri wamagawo anu amagetsi kapena sockets. Nyumba yogona ziwiri mwachitsanzo ikhoza kukhala ndi mabwalo amagetsi a 2 x 32A kuti alekanitse masiketi apamwamba ndi apansi. Nyumba zazikulu zimatha kukhala ndi mabwalo 32 A.
40 amp- Zophikira / ma hobs amagetsi / zosambira zazing'ono
50 amp- 10kw Mashawa amagetsi / Machubu otentha.
63 ampe- nyumba yonse
Liper Breakers amaphimba kuyambira 1A mpaka 63A
Dongosolo Lalifupi Lalifupi - Kilo Amperes (kA)
Short Circuit ndi chifukwa cha vuto penapake pamagetsi kapena chipangizo chamagetsi ndipo ndi chowopsa kwambiri kuposa kulemetsa.
Ma MCB omwe amagwiritsidwa ntchitomakhazikitsidwe apanyumbaamavoteledwa pa6kA pakapena 6000 amps. Ubale pakati pa ma voliyumu wamba (240V) ndi mphamvu zamagetsi zomwe zimagwiritsidwa ntchito m'nyumba zimatanthawuza kuti kuchuluka kwamagetsi komwe kumachitika chifukwa chafupipafupi sikuyenera kupitilira 6000 amps. Komabe, muzamalonda ndi mafakitale, mukamagwiritsa ntchito 415V ndi makina akuluakulu, ndikofunikira kugwiritsa ntchito10kA kuadavotera MCBs.
Tripping Curve
'Tripping Curve' ya MCB imalola dziko lenileni ndipo nthawi zina kufunikira kokulirapo. Mwachitsanzo, malo ogulitsa nyumba zapanyumba, makina akuluakulu nthawi zambiri amafunikira kuwonjezereka kwamphamvu kopitilira muyeso wawo wanthawi zonse kuti athe kuthana ndi vuto la ma motors akulu. Kuthamanga kwachiduleku kumatenga masekondi, kumaloledwa ndi MCB chifukwa ndi kotetezeka pakanthawi kochepa.
Palimfundo zitatu Zopindika Mitunduzomwe zimalola kuti pakhale mafunde amagetsi osiyanasiyana:
Lembani B MCBsamagwiritsidwa ntchito muchitetezo cha m'nyumbakomwe kuli kofunikira pang'ono chilolezo cha opaleshoni. Kuphulika kwakukulu kulikonse m'nyumba kumakhala chifukwa cha vuto, kotero kuti kuchuluka kwaposachedwa komwe kumaloledwa kumakhala kochepa.
Lembani C MCBsmaulendo pakati pa 5 ndi 10 nthawi zonse zodzaza zapano ndipo zimagwiritsidwa ntchitomalo ogulitsa ndi opepuka amakampanizomwe zitha kukhala ndi mabwalo akulu ounikira fulorosenti, zosinthira ndi zida za IT monga ma seva, ma PC ndi osindikiza.
Lembani D MCBsamagwiritsidwa ntchito mukatundu wa mafakitalemonga mafakitale omwe amagwiritsa ntchito ma motors akulu okhotakhota, makina a X-ray kapena ma compressor.
Mitundu itatu ya MCBs imapereka chitetezo chodumphadumpha mkati mwa gawo limodzi mwa magawo khumi a sekondi. Izi zikutanthauza kuti, kuchulukitsitsa ndi nthawi zikadutsa, MCB imayenda mkati mwa masekondi 0.1.
Chifukwa chake, Liper nthawi zonse amakwaniritsa zosowa zanu zonse.
