Mwezi watha, mwiniwake wa malo opangira zinthu, Bambo Carter, anakumana ndi vuto lokhumudwitsa: magetsi a malo ake opangira zinthu ankagwa mobwerezabwereza, ndipo zipangizo zamagetsi zinkawonongeka nthawi zina. Ataitana katswiri wamagetsi kuti akawone, chifukwa chake chinali chosavuta modabwitsa—anayika molakwika ma circuit breakers a 1P mu chingwe chachikulu chamagetsi chomwe chimafuna chitetezo cha 2P. Cholakwika ichi sichinangosokoneza kupanga komanso chinayambitsa ndalama zosafunikira zokonzera. Kwa mainjiniya ambiri amagetsi, ogwira ntchito zogula zinthu, kapena eni mabizinesi ang'onoang'ono,Kusankha nambala yoyenera ya pole ya ma circuit breaker ndi ntchito yofunikira koma yofunika kwambiriKusankha kolakwika kungayambitse ngozi zachitetezo, kulephera kwa zida, kapena kutseka kupanga. Lero, tiwunika bwino momwe ma circuit breaker a 1P, 2P, 3P, ndi 4P amagwirira ntchito kuti tikuthandizeni kusankha bwino.
Choyamba, Kodi "Nambala ya Pole" ya Circuit Breaker ndi Chiyani?
Nambala ya pole ya circuit breaker imatanthauza kuchuluka kwa pole zonyamula mphamvu (ma conductive loops) zomwe zili nazo, zomwe zimatsimikiza kuchuluka kwa mizere yomwe ingathe kuwongolera ndikudula nthawi imodzi. Mwachidule, nambala ya pole imagwirizana mwachindunji ndi kuchuluka kwa chitetezo cha circuit ndi mtundu wa makina opangira magetsi omwe imasintha. Kenako, tigawa makhalidwe ndi zochitika za nambala iliyonse ya pole.
Chothyola Circuit cha 1P: Choyenera Ma Circuit a Nthambi ya Gawo Limodzi Yokhala ndi Chitetezo Chosavuta
Mawonekedwe:Ma circuit breaker a 1P amangolamulira ndikuchotsa waya wamoyo (L wire), popanda kugwiritsa ntchito waya wa neutral (N wire). Ali ndi kapangidwe kosavuta komanso mtengo wotsika, makamaka amapereka chitetezo cha overload ndi short-circuit ku ma circuit a single-phase.
Zochitika Zogwiritsira Ntchito:Amagwiritsidwa ntchito kwambiri m'mabwalo a nthambi imodzi yokhala ndi mphamvu zochepa komanso zinthu zosavuta, monga mabwalo owunikira m'nyumba zogona, mabwalo a soketi a zida zazing'ono zapakhomo (monga nyali za patebulo, zoyatsira mafoni), ndi mabwalo a nthambi imodzi m'mabwalo owunikira maofesi.
Chotsegula Chigawo cha 2P: Chabwino Kwambiri pa Ma Circuits Aakulu a Gawo Limodzi kapena Zinthu Zofunika
Mawonekedwe:Ma circuit breaker a 2P amatha kuwongolera ndikuchotsa waya wamoyo ndi waya wa neutral nthawi imodzi. Poyerekeza ndi 1P, ali ndi chitetezo chokwanira, kupewa zoopsa zomwe zingachitike chifukwa cha waya wa neutral womwe ukuchajidwa chifukwa cha zolakwika.
Zochitika Zogwiritsira Ntchito:Yoyenera ma loops amphamvu a gawo limodzi (monga switch yayikulu ya mabanja okhala), ma circuit ofunikira a gawo limodzi (monga ma air conditioner, ma water heater, ndi mafiriji okhala ndi mphamvu zambiri), ndi ma circuit a gawo limodzi omwe amafunikira chitetezo champhamvu (monga ma circuit a zida zachipatala m'zipatala zazing'ono ndi ma circuit a zida zolondola m'ma laboratories).
Chotsegula Chigawo cha 3P: Cha Magawo Atatu a Mawaya Atatu a Machitidwe a Mafakitale
Mawonekedwe:Ma circuit breaker a 3P amapangidwira makina opangira magetsi a mawaya atatu a magawo atatu (opanda waya wapakati). Amalamulira ndikuchotsa mawaya atatu amoyo (L1, L2, L3) nthawi imodzi, kupereka chitetezo cha overload ndi short-circuit pazida za magawo atatu.
Zochitika Zogwiritsira Ntchito:Amagwiritsidwa ntchito kwambiri m'mabizinesi amakampani ndi migodi, malo ogwirira ntchito, ndi malo ena okhala ndi makina a mawaya atatu a magawo atatu. Zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo ma mota a magawo atatu osasinthasintha, ma compressor a mpweya a magawo atatu, ma uvuni amagetsi a magawo atatu, ndi zida zina zamafakitale za magawo atatu zomwe sizifuna waya wopanda mbali kuti zigwiritsidwe ntchito.
Chothyola Ma Circuit cha 4P: Choyenera Makina Atatu a Mawaya Anayi Okhala ndi Chitetezo cha Waya Wosalowerera
Mawonekedwe:Ma circuit breaker a 4P amalamulira ndikuchotsa mawaya atatu amoyo ndi waya umodzi wosalowerera nthawi imodzi, kusintha makina opangira magetsi a mawaya anayi a magawo atatu. Amatha kuteteza bwino ma circuit ndi zida zikachitika zolakwika mu waya wosalowerera, ndikuwonetsetsa kuti makina onse opangira magetsi ali otetezeka.
Zochitika Zogwiritsira Ntchito:Amagwiritsidwa ntchito kwambiri m'makina amphamvu amagetsi a magawo atatu omwe amafunika kuteteza waya wopanda mbali, monga chosinthira chachikulu cha nyumba zamalonda (chothandizira zida za magawo atatu ndi zida zapakhomo za gawo limodzi), mabokosi ogawa mawaya anayi a magawo atatu m'masitolo akuluakulu, malo osungira deta okhala ndi katundu wosakanikirana wa magawo atatu ndi gawo limodzi, ndi malo atsopano opangira magetsi (monga makina a photovoltaic ndi osungira mphamvu) omwe amafunikira chitetezo chokwanira cha waya wopanda mbali.
Chidule Chachikulu Chosankha
1. Pa ma circuits a nthambi imodzi (magetsi, zida zazing'ono):Sankhani 1P;
2. Pa ma circuits ofunikira a gawo limodzi kapena main loops:Sankhani 2P;
3. Zipangizo zamafakitale zamagawo atatu zamawaya atatu (zopanda waya wapakati):Sankhani 3P;
4. Pa makina a mawaya anayi a magawo atatu okhala ndi waya wopanda malire (nyumba zamalonda, malo osungira deta):Sankhani 4P.
Kusankha nambala yoyenera ya pole yothyola circuit ndiye njira yoyamba yodzitetezera ku chitetezo chamagetsi. Ngati simukudziwabe za kusankha nambala ya pole pa ntchito yanu, musazengereze kutero.Lumikizanani ndi alangizi athu aukadaulo kuti mupeze upangiri wa akatswiri komanso mayankho okonzedwa mwamakonda.
