I. Mfundo Zazikulu za Mabokosi Ogawa
Bokosi logawa ndi chida chapakati pamakina amagetsi omwe amagwiritsidwa ntchito pogawa mphamvu zamagetsi, kuwongolera mabwalo ndi kuteteza zida zamagetsi. Amagawa mphamvu zamagetsi kuchokera kumagetsi (monga ma transformers) kupita ku zipangizo zosiyanasiyana zamagetsi ndikugwirizanitsa ntchito zotetezera monga kuchulukitsitsa, kufupikitsa ndi kutuluka.

Zogwiritsa ntchito kwambiri:

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

Chitetezo chozungulira (kuchulukirachulukira, kuzungulira kwachidule, kutayikira).

Yang'anirani mawonekedwe a dera (voltage ndi mawonekedwe apano).

Ii. Gulu la Mabokosi Ogawa
Pogwiritsa ntchito zochitika:

Bokosi logawa m'nyumba: Laling'ono kukula, lokhala ndi chitetezo chochepa, chophatikizira chitetezo chotuluka, zosinthira mpweya, ndi zina zambiri.

Bokosi logawa mafakitale: Mphamvu yayikulu, chitetezo chapamwamba (IP54 kapena pamwambapa), chothandizira kuwongolera madera ovuta.

Bokosi logawa panja: Lopanda madzi komanso lopanda fumbi (IP65 kapena pamwambapa), loyenera malo otseguka.

Mwa njira yoyika:

Mtundu wowonekera wowonekera: Wokhazikika pakhoma, wosavuta kukhazikitsa.

Mtundu wobisika: Woyikidwa pakhoma, ndi wokongola koma zomangamanga ndizovuta.

Mwa mawonekedwe:

Mtundu wokhazikika: Zida zimayikidwa mokhazikika, ndi mtengo wotsika.

Mtundu wa drawer (bokosi logawa modula): Mapangidwe amtundu, osavuta kukonza ndi kukulitsa.

Iii. Kapangidwe ka Mabokosi Ogawa
Thupi la bokosi:

Zida: Chitsulo (mbale yachitsulo yozizira, chitsulo chosapanga dzimbiri) kapena chosapanga chitsulo (pulasitiki ya engineering).

Mulingo wachitetezo: Ma IP code (monga IP30, IP65) amawonetsa kuthekera kwa fumbi ndi madzi.

Zida zamagetsi zamkati:

Zowononga ma circuit: Kuteteza mochulukira/kufupikitsa (monga ma switch a mpweya, zomangira zomangira).

Cholumikizira: Kudula magetsi pamanja.

Chipangizo choteteza kutayikira (RCD): Imazindikira kutayikira kwapano komanso maulendo.

Mita yamagetsi: Kuyeza mphamvu yamagetsi.

Contactor: Imawongolera patali kuyatsa ndi kuyimitsa dera.

Surge protector (SPD): Imateteza ku mphezi kapena kuphulika.

Zothandizira:

Mabasi (mabasi amkuwa kapena aluminiyamu), midadada yama terminal, magetsi owonetsera, mafani ozizira, ndi zina zambiri.

Iv. Technical Parameters ya bokosi logawa
Zovoteledwa pano: monga 63A, 100A, 250A, zomwe ziyenera kusankhidwa kutengera mphamvu yonse ya katunduyo.

Mphamvu yamagetsi: Nthawi zambiri 220V (gawo limodzi) kapena 380V (magawo atatu).

Gulu lachitetezo (IP) : monga IP30 (yopanda fumbi), IP65 (yopanda madzi).

Kupirira kwakanthawi kochepa: Nthawi yopirira nthawi yayitali (monga 10kA/1s).

Kuthyola mphamvu: Kuwonongeka kwakukulu komwe woyendetsa dera amatha kudulira.

V. Maupangiri Osankha Mabokosi Ogawa
Malingana ndi mtundu wa katundu:

Dera lowunikira: Sankhani 10-16A miniature circuit breaker (MCB).

Zipangizo zamagalimoto: Ma relay otenthetsera kapena zoyatsira magetsi zamtundu wina zimafunikira kufananizidwa.

Malo okhudzidwa kwambiri (monga mabafa) : Chipangizo choteteza kutayikira (30mA) chiyenera kukhazikitsidwa.

Kuwerengera mphamvu

Zomwe zilipo panopa ndi ≤ chiwerengero chamakono cha bokosi logawa × 0.8 (malire achitetezo).

Mwachitsanzo, okwana katundu mphamvu ndi 20kW (atatu-gawo), ndipo panopa ndi pafupifupi 30A. Ndikofunikira kusankha bokosi logawa la 50A.

Kusinthasintha kwa chilengedwe

Malo achinyezi: Sankhani bokosi lachitsulo chosapanga dzimbiri + kalasi yotetezedwa kwambiri (IP65).

Malo otentha kwambiri: Mabowo ochotsa kutentha kapena mafani amafunikira.

Zofunikira zowonjezera:

Sungani 20% ya malo opanda kanthu kuti muthandizire kuwonjezera madera atsopano pambuyo pake.

Vi. Kukhazikitsa ndi Kusamalira Kusamala
Zofunikira pakuyika:

Malowa ndi owuma komanso mpweya wabwino, kutali ndi zipangizo zoyaka moto.

Bokosilo limakhala lokhazikika kuti liteteze kuopsa kwa kuwonongeka kwa magetsi.

Maonekedwe amtundu wawaya (waya wamoyo wofiira/chikasu/wobiriwira, waya wosalowerera wabuluu, waya wapansi wachikasu wobiriwira).

Mfundo zazikuluzikulu zosamalira:

Nthawi zonse fufuzani ngati mawaya ali otayirira kapena oxidized.

Sambani fumbi (kupewa mabwalo amfupi).

Yesani chipangizo choteteza (monga kukanikiza batani loyesa kuteteza kutayikira kamodzi pamwezi).

Vii. Mavuto Wamba ndi Mayankho
Kuyenda pafupipafupi

Chifukwa: Kuchulukirachulukira, kuzungulira kwafupipafupi kapena kutayikira.

Kuthetsa mavuto: Chotsani mzere wa katundu ndi mzere ndikupeza dera lolakwika.

Kudumpha kwa chipangizo choteteza kutayikira

Zotheka: Kuwonongeka kowonongeka kwa dera, kutuluka kwa magetsi kuchokera ku zipangizo.

Chithandizo: Gwiritsani ntchito megohmmeter kuyesa kukana kwa insulation.

Bokosi likutentha kwambiri.

Chifukwa: Kuchulukirachulukira kapena kusalumikizana bwino.

Yankho: Chepetsani katunduyo kapena sungani midadada yotsekera.

Viii. Malamulo a Chitetezo
Iyenera kutsata miyezo ya dziko (monga GB 7251.1-2013 "Low-voltage Switchgear Assemblies").

Mukakhazikitsa ndi kukonza, mphamvu iyenera kudulidwa ndipo ntchitoyi iyenera kuchitidwa ndi akatswiri amagetsi.

Ndizoletsedwa kusintha mabwalo amkati mwakufuna kapena kuchotsa zida zoteteza.
