I. Malingaliro Oyambira a Mabokosi Ogawa
Bokosi logawa ndi chipangizo chachikulu mu dongosolo lamagetsi chomwe chimagwiritsidwa ntchito pogawa mphamvu zamagetsi pakati, kuwongolera ma circuit ndi kuteteza zida zamagetsi. Chimagawa mphamvu zamagetsi kuchokera ku magwero amagetsi (monga ma transformer) kupita ku zida zosiyanasiyana zamagetsi ndipo chimagwirizanitsa ntchito zoteteza monga kupitirira muyeso, kufupika kwa magetsi ndi kutuluka kwa madzi.

Ntchito zazikulu:

Kugawa ndi kuwongolera mphamvu zamagetsi (monga magetsi owunikira ndi zida zamagetsi).

Chitetezo cha dera (kuchuluka kwa katundu, kufupika kwa dera, kutayikira kwa madzi).

Yang'anirani momwe dera likuonekera (voltage ndi current display).

II. Kugawa Mabokosi Ogawa
Malinga ndi zochitika zogwiritsira ntchito:

Bokosi logawa zinthu m'nyumba: Laling'ono kukula, lokhala ndi chitetezo chochepa, lophatikiza chitetezo chotuluka madzi, ma switch a mpweya, ndi zina zotero.

Bokosi logawa mafakitale: Mphamvu yayikulu, mulingo wotetezeka kwambiri (IP54 kapena kupitirira apo), wothandizira kuwongolera dera lovuta.

Bokosi logawa zinthu panja: Losalowa madzi komanso losapsa fumbi (IP65 kapena kupitirira apo), loyenera malo otseguka.

Mwa njira yokhazikitsira:

Mtundu woyika wowonekera: Wokhazikika mwachindunji pakhoma, wosavuta kuyika.

Mtundu wobisika: Woyikidwa pakhoma, ndi wokongola koma kapangidwe kake ndi kovuta.

Mwa mawonekedwe a kapangidwe kake:

Mtundu wokhazikika: Zigawo zimayikidwa mwanjira yokhazikika, ndi mtengo wotsika.

Mtundu wa kabati (bokosi logawa modular): Kapangidwe ka modular, koyenera kukonza ndi kukulitsa.

III. Kapangidwe ka Mabokosi Ogawa
Bokosi lokhala ndi zinthu:

Zipangizo: Chitsulo (mbale yachitsulo yozungulira yozizira, chitsulo chosapanga dzimbiri) kapena chosakhala chachitsulo (pulasitiki yaukadaulo).

Mulingo woteteza: Ma code a IP (monga IP30, IP65) akusonyeza mphamvu yolimbana ndi fumbi ndi madzi.

Zida zamagetsi zamkati:

Zothira magetsi: Chitetezo cha overload/short-circuit (monga ma air switch, ma molded case circuit breakers).

Chochotsera magetsi: Dulani magetsi ndi manja.

Chipangizo choteteza kutuluka kwa madzi (RCD): Chimazindikira kutuluka kwa madzi ndi maulendo.

Chiyeso cha magetsi: Kuyeza mphamvu yamagetsi.

Wothandizira: Amalamulira patali kuyatsa ndi kutseka kwa dera.

Choteteza kugwedezeka kwa magetsi (SPD): Chimateteza ku mphezi kapena kugwedezeka kwa magetsi.

Zopangira zothandizira:

Mabasi (mabasi a mkuwa kapena aluminiyamu), ma terminal block, magetsi owunikira, mafani ozizira, ndi zina zotero.

Iv. Magawo aukadaulo a bokosi logawa
Mphamvu yamagetsi yoyesedwa: monga 63A, 100A, 250A, yomwe iyenera kusankhidwa kutengera mphamvu yonse ya katunduyo.

Voltage yovotera: Nthawi zambiri imakhala 220V (gawo limodzi) kapena 380V (gawo lachitatu).

Mulingo woteteza (IP): monga IP30 (yosalowa m'fumbi), IP65 (yosalowa m'madzi).

Kupirira kwafupipafupi: Nthawi yolimbana ndi mphamvu yafupipafupi (monga 10kA/1s).

Mphamvu yothyola: Mphamvu yayikulu kwambiri yomwe chothyola mawaya chingadule bwino.

V. Buku Lotsogolera Kusankha Mabokosi Ogawa
Malinga ndi mtundu wa katundu:

Chigawo chowunikira: Sankhani chotsegula chigawo chaching'ono cha 10-16A (MCB).

Zipangizo zamagalimoto: Ma relay a kutentha kapena ma circuit breaker a injini ayenera kufananizidwa.

Malo omwe ali ndi vuto la kuthamanga kwa magazi (monga mabafa): Chipangizo choteteza kutuluka kwa madzi (30mA) chiyenera kuyikidwa.

Kuwerengera mphamvu

Mphamvu yonse ndi ≤ mphamvu yovotera ya bokosi logawa × 0.8 (malire achitetezo).

Mwachitsanzo, mphamvu yonse yonyamula ndi 20kW (magawo atatu), ndipo mphamvu yamagetsi ndi pafupifupi 30A. Ndikofunikira kusankha bokosi logawa la 50A.

Kusinthasintha kwa chilengedwe

Malo onyowa: Sankhani bokosi lachitsulo chosapanga dzimbiri + chitetezo chapamwamba (IP65).

Malo otentha kwambiri: Mabowo kapena mafani otenthetsera kutentha amafunika.

Zofunikira Zowonjezera:

Sungani 20% ya malo opanda kanthu kuti muwonjezere ma circuit atsopano pambuyo pake.

Vi. Malangizo Okhazikitsa ndi Kukonza
Zofunikira pakuyika:

Malowa ndi ouma komanso opumira bwino, kutali ndi zinthu zoyaka moto.

Bokosilo lili ndi maziko olimba kuti lipewe kutayikira kwa magetsi.

Mafotokozedwe a mtundu wa waya (waya wamoyo wofiira/wachikasu/wobiriwira, waya wabuluu wosalowerera, waya wophwanyika wobiriwira wachikasu).

Mfundo zazikulu zosamalira:

Onetsetsani nthawi zonse ngati mawayawo ndi otayirira kapena oxidized.

Tsukani fumbi (kuti mupewe kufalikira kwa mafunde afupiafupi).

Yesani chipangizo choteteza (monga kukanikiza batani loyesera chitetezo chotulutsa madzi kamodzi pamwezi).

Vii. Mavuto ndi Mayankho Ofala
Kugwa pafupipafupi

Chifukwa: Kudzaza kwambiri, kufupika kwa mpweya kapena kutayikira kwa madzi.

Kuthetsa Mavuto: Chotsani mzere wonyamula katundu ndi mzere ndikupeza dera lolakwika.

Kugwa kwa chipangizo choteteza kutayikira kwa madzi

Zotheka: Kuteteza kwa magetsi kuwonongeka, kutayikira kwa magetsi kuchokera ku zipangizo.

Chithandizo: Gwiritsani ntchito megohmmeter kuti muyese kukana kwa kutentha.

Bokosilo likutentha kwambiri.

Chifukwa: Kulemera kwambiri kapena kukhudzana kosayenera.

Yankho: Chepetsani katundu kapena mangani ma terminal blocks.

Viii. Malamulo a Chitetezo
Iyenera kutsatira miyezo ya dziko (monga GB 7251.1-2013 “Magulu Osinthira Otsika a Switchgear”).

Poika ndi kusamalira, magetsi ayenera kudulidwa ndipo ntchitoyo iyenera kuchitidwa ndi akatswiri a zamagetsi.

Ndikoletsedwa kusintha ma circuits amkati mwakufuna kapena kuchotsa zida zodzitetezera.
