Mitundu ya Circuit Breaker ndi Guide Yosankha

KumvetsetsaZosokoneza DeraZipangizo Zofunika Kwambiri Zotetezera mu Machitidwe Amagetsi

Mawu akuti "circuit breaker" ndi ofala kwambiri m'dziko la uinjiniya wamagetsi ndi chitetezo chapakhomo. Ma circuit breaker ndi zinthu zofunika kwambiri zomwe zimateteza ma circuit amagetsi ku overloads ndi short circuit, zomwe zimaonetsetsa kuti ma electronic system ndi omwe amagwiritsa ntchito ndi otetezeka. Nkhaniyi ifotokoza bwino ntchito, mitundu, ndi kufunika kwa ma circuit breaker m'ma electronic system amakono.

Kodi chosokoneza mawaya n'chiyani?

Chotsekereza magetsi ndi chosinthira magetsi chokha chomwe chimaletsa kuyenda kwa magetsi mu dera chikazindikira vuto linalake, monga kudzaza kwambiri kapena dera lalifupi. Mosiyana ndi ma fuse, omwe ayenera kusinthidwa akaphulika, ma circuit breaker amatha kubwezeretsedwanso akagwa, zomwe zimapangitsa kuti akhale njira yabwino komanso yothandiza yotetezera dera. Ma circuit breaker ndi ofunikira popewa moto wamagetsi, kuwonongeka kwa zida, ndi zoopsa zina zokhudzana ndi kusowa kwa magetsi.

Momwe ma circuit breaker amagwirira ntchito

Ma circuit breaker amagwira ntchito pogwiritsa ntchito njira ziwiri zazikulu: kutentha ndi maginito.

1. Njira yotetezera kutentha: Njirayi imagwiritsa ntchito chingwe cha bimetallic chomwe chimapindika pamene mphamvu yamagetsi ili pamwamba kwambiri. Mphamvu yamagetsi ikapitirira mtengo wokonzedweratu, chingwe chachitsulocho chimapindika mokwanira kuyambitsa chosweka chamagetsi, motero chimadula dera.

2. Kagwiridwe ka maginito: Kagwiridwe kameneka kamadalira mphamvu ya maginito. Pamene dera lalifupi la magetsi lachitika, kulowa kwa mphamvu yamagetsi mwadzidzidzi kumapanga mphamvu ya maginito yokwanira kukoka lever ndikugwetsa chosokoneza dera.

Ma circuit breaker ena amakono amaphatikiza njira zonse ziwiri kuti atetezedwe bwino, zomwe zimapangitsa kuti pakhale yankho lodalirika pamavuto osiyanasiyana amagetsi.

Mitundu ya ma circuit breakers

Pali mitundu ingapo ya ma circuit breaker, iliyonse ili ndi cholinga chake:

1. Ma Miniature Circuit Breaker (MCB): Ma circuit breaker amenewa amagwiritsidwa ntchito kwambiri m'nyumba zogona komanso zamalonda kuti ateteze ku overload ndi short circuits. Ndi ang'onoang'ono ndipo amatha kuthana ndi mphamvu yamagetsi yochepa mpaka yapakatikati.

2. Chotsukira Mphamvu Yotsalira (RCCB): Zipangizozi zimateteza kugwedezeka kwa magetsi pozindikira kusalingana kwa mphamvu. Ngati vuto lapezeka, RCCB imagunda ndikudula magetsi.

3. Ma Residual Current Circuit Breakers (ELCB): Mofanana ndi Residual Current Circuit Breakers (RCCB), ma ELCB amateteza ku zolakwika za nthaka. Ndi ofunikira kwambiri m'malo onyowa monga m'bafa ndi m'khitchini.

4. Zothyola Mpweya (ACB): Zothyola mpweya zimagwiritsidwa ntchito m'mafakitale kuti zithetse mphamvu yamagetsi yambiri komanso kuteteza ku kupitirira muyeso, kufupika kwa magetsi, ndi vuto la nthaka.

5. Ma Hydraulic Magnetic Circuit Breakers: Izi nthawi zambiri zimagwiritsidwa ntchito m'magetsi akuluakulu ndipo zimapereka njira yolimba yotetezera ku mafunde amphamvu.

Kufunika kwa Ophwanya Dera

Kufunika kwa ma circuit breaker sikuyenera kunyalanyazidwa. Ndiwo mzere woyamba wodzitetezera ku ngozi zamagetsi, kuteteza moyo ndi katundu. Ma circuit breaker amaletsa kuyenda kwa magetsi nthawi yomweyo, zomwe zimathandiza kupewa moto wamagetsi, kuwonongeka kwa zida, komanso kuvulala kwa anthu.

Kuphatikiza apo, ma circuit breaker amathandiza kukonza magwiridwe antchito amagetsi. Mwa kupewa kuchulukira kwa zinthu, ma circuit breaker amaonetsetsa kuti zida zamagetsi zikugwira ntchito bwino, motero zimawonjezera nthawi yogwirira ntchito ndikuchepetsa ndalama zokonzera.

Powombetsa mkota

Mwachidule, ma circuit breaker ndi gawo lofunika kwambiri pamakina amagetsi amakono. Kutha kwawo kuzindikira ndikuyankha ku zolakwika zamagetsi ndikofunikira kuti pakhale chitetezo komanso magwiridwe antchito abwino. Kumvetsetsa mitundu yosiyanasiyana ya ma circuit breaker ndi ntchito zawo kungathandize eni nyumba ndi mabizinesi kupanga zisankho zolondola zokhudza makina awo amagetsi. Pamene ukadaulo ukupitilira kupita patsogolo, ma circuit breaker mosakayikira apitilizabe kusintha, zomwe zikuwonjezera ntchito yawo poteteza zomangamanga zathu zamagetsi.
