Mitundu ya Circuit Breaker ndi Guide Yosankha

Zosokoneza Ma Circuit: Kumvetsetsa Kufunika Kwake mu Machitidwe Amagetsi

Mu nkhani za uinjiniya wamagetsi ndi chitetezo, mawu oti "circuit breaker" ndi ofunikira kwambiri. Circuit breaker ndi switch yamagetsi yokha yomwe imapangidwa kuti iteteze ma circuit ku kuwonongeka komwe kumachitika chifukwa cha kuchuluka kwa ma circuit kapena ma short circuit. Ntchito yake yayikulu ndikusokoneza mphamvu yamagetsi pamene vuto lapezeka, potero kupewa zoopsa monga moto wamagetsi kapena kuwonongeka kwa zida. Nkhaniyi ifufuza mbali zosiyanasiyana za ma circuit breaker, kuphatikizapo mitundu yawo, ntchito zawo, ndi gawo lofunika lomwe amachita m'makina amagetsi amakono.

Kodi chodulira mawaya chimatchedwanso chiyani?

Chotsekera magetsi, chomwe chimadziwikanso kuti magneto-thermal breaker, ndi gawo lofunika kwambiri pakupanga magetsi amakono.

Ntchito za Circuit Breakers

Ntchito yaikulu ya chotseka mawaya ndi ngati chipangizo chotetezera kuti chiziyang'anira mphamvu ya magetsi mu dera. Mphamvu yamagetsi ikapitirira malire omwe adakhazikitsidwa kale, chotseka mawaya chimagwa, ndikudula magetsi. Izi sizimangoteteza zingwe ndi zida zolumikizidwa komanso zimateteza anthu omwe angagwidwe ndi magetsi.

Pali mfundo ziwiri zazikulu zogwiritsira ntchito ma circuit breakers:kutenthandimaginito. Ma thermal circuit breakers amagwiritsa ntchito bimetallic strips; pamene current ili yokwera kwambiri, bimetallic strip imatentha ndikupindika, zomwe zimapangitsa kuti circuit breaker igwe. Ma magnetic circuit breakers amagwiritsa ntchito ma electromagnets; pamene current idutsa malire enaake, electromagnet imagwirira ntchito, zomwe zimapangitsa kuti circuit breaker igwe. Ma circuit breakers ena amakono amaphatikiza njira zonse ziwiri kuti apititse patsogolo chitetezo.

Mitundu ya Ophwanya Dera

Ma circuit breaker amabwera m'mitundu yosiyanasiyana, iliyonse yopangidwira ntchito ndi malo enaake. Mitundu yodziwika kwambiri ndi iyi:

1. Zothyola Zazing'ono Zazing'ono (MCB):Ma Miniature circuit breaker amagwiritsidwa ntchito kwambiri m'nyumba ndi m'mabizinesi kuti apewe kudzaza kwambiri ndi ma short circuit. Ndi ang'onoang'ono kukula kwake ndipo ndi osavuta kuyika m'mabokosi ogawa.
2. Chotsukira Dera Chotsalira (RCCB):Chipangizochi chomwe chimadziwikanso kuti RCD, chimateteza kugwedezeka kwa magetsi pozindikira kusalingana kwa mphamvu yamagetsi. Ngati vuto lachitika, monga munthu wokhudza waya wamoyo, RCCB imagwa, ndikudula magetsi.
3. Ma Molded Case Circuit Breakers (MCCBs): Ma circuit breakers awa amagwiritsidwa ntchito m'mafakitale ndipo amatha kuthana ndi mafunde amphamvu. Ma MCCB amapereka chitetezo champhamvu, chofupikitsa magetsi, komanso choteteza ku vuto la nthaka.
4. Ma Air Circuit Breaker (ACB): Ma air circuit breaker nthawi zambiri amagwiritsidwa ntchito pamagetsi amphamvu kwambiri ndipo amapangidwira kusokoneza mafunde akuluakulu. Amapezeka nthawi zambiri m'malo osungira magetsi ndi mafakitale akuluakulu.
5. Zophulitsira Maginito a Hydraulic:Ma circuit breaker awa amagwiritsa ntchito njira za hydraulic kuti agwe, zomwe zimapereka yankho lodalirika pakugwiritsa ntchito mphamvu yamagetsi yamphamvu.

Kufunika kwa ma circuit breakers

Kufunika kwa ma circuit breaker sikunganyalanyazidwe. Ndi zinthu zofunika kwambiri zomwe zimatsimikizira kuti magetsi amagwira ntchito bwino komanso modalirika. Mwa kupewa kuchulukirachulukira kwa magetsi ndi ma short circuit breaker, ma circuit breaker amathandiza kuchepetsa chiopsezo cha moto wamagetsi, kuwonongeka kwa zida, komanso kuvulala kwa anthu. Kuphatikiza apo, pakachitika vuto, ma circuit breaker amatha kubwezeretsedwanso mwachangu komanso mosavuta, motero kukonza magwiridwe antchito amagetsi onse.

Kuwonjezera pa ntchito zawo zoteteza, ma circuit breaker amachita gawo lofunika kwambiri potsatira malamulo ndi miyezo yamagetsi. Madera ambiri amafuna kuti ma circuit breaker akhazikitsidwe m'nyumba zogona komanso zamalonda kuti zitsimikizire kuti ndi otetezeka komanso odalirika.

Mwachidule

Mwachidule, ma circuit breaker ndi zida zofunika kwambiri pa ntchito zamagetsi. Amateteza ma circuit ku zinthu zambirimbiri komanso ma short circuit, zomwe zimapangitsa kuti akhale ofunikira kwambiri poteteza malo okhala ndi mafakitale. Pamene ukadaulo ukupita patsogolo, ma circuit breaker akupitilizabe kusintha kuti apereke chitetezo chokwanira komanso magwiridwe antchito. Kumvetsetsa mitundu yosiyanasiyana ya ma circuit breaker ndi ntchito zawo ndikofunikira kwa aliyense wogwira ntchito zamagetsi, chifukwa kumatsimikizira kuti machitidwe amagetsi amagwira ntchito bwino komanso motetezeka. Kaya m'nyumba, maofesi, kapena mafakitale, ma circuit breaker akadali gawo lofunikira kwambiri pa zomangamanga zamagetsi zamakono.
