Kodi mukudziwa kuti Circuit Breakers ndi chiyani?

Kodi Circuit Breakers ndi chiyani?

Chosinthira magetsi chomwe chimapangidwa kuti chiteteze magetsi kuti asawonongeke chifukwa cha kuchuluka kwa magetsi/kuchuluka kwa magetsi kapena kufupika kwa magetsi chimadziwika kuti chosokoneza magetsi. Ntchito yake yayikulu ndikusokoneza magetsi pambuyo poti ma relay oteteza awona vuto.

Ntchito ya Circuit Breaker Switch.

Chotsekereza mawaya chimagwira ntchito ngati chipangizo chotetezera motero chimaletsa kuwonongeka kwa ma mota ndi mawaya pamene magetsi oyenda mumagetsi apitirira malire ake. Chimachita izi pochotsa magetsi mumagetsi pakagwa vuto losatetezeka.

Kodi DC Circuit Breakers Imagwira Ntchito Bwanji?

Monga momwe dzina lawo likusonyezera, ma Direct Current (DC) circuit breakers amateteza zipangizo zamagetsi zomwe zimagwira ntchito pa direct current. Kusiyana kwakukulu pakati pa direct current ndi alternating current ndikuti voltage output mu DC ndi yokhazikika. Mosiyana ndi zimenezi, voltage output mu Alternating Current (AC) imazungulira kangapo sekondi iliyonse.

Kodi ntchito ya DC Circuit Breaker ndi yotani?

Mfundo zomwezo zotetezera kutentha ndi maginito zimagwiranso ntchito pa ma DC breakers monga momwe zimagwirira ntchito pa ma AC circuit breakers:
Chitetezo cha kutentha chimagunda chodulira magetsi cha DC pamene mphamvu yamagetsi yapitirira mtengo wovomerezeka. Kutentha kwa bimetallic kumakula ndikugunda chodulira magetsi mu njira yotetezera iyi. Chitetezo cha kutentha chimagwira ntchito mwachangu chifukwa mphamvu yamagetsi imapanga kutentha kochulukirapo kuti ikule ndikutsegula kulumikizana kwamagetsi chifukwa mphamvu yamagetsi ndi yayikulu. Chitetezo cha kutentha cha chodulira magetsi cha DC chimateteza ku mphamvu yamagetsi yochulukirapo yomwe ili pamwamba pang'ono kuposa mphamvu yamagetsi yogwiritsira ntchito.
Ngati pali mafunde amphamvu a fault current, chitetezo cha maginito chimagunda DC circuit breaker, ndipo nthawi zonse yankho limakhala nthawi yomweyo. Monga ma AC circuit breaker, ma DC circuit breaker ali ndi mphamvu yothyola yomwe imayimira fault current yofunika kwambiri yomwe ingasokonezedwe.
Popeza kuti mphamvu yamagetsi imayimitsidwa nthawi zonse ndi ma DC circuit breaker zikutanthauza kuti ma circuit breaker ayenera kutsegula magetsi kwambiri kuti asokoneze mphamvu yamagetsi. Chitetezo cha maginito cha ma DC circuit breaker chimateteza ma short circuit ndi zolakwika zomwe zimakhala zazikulu kwambiri kuposa overload.

Mitundu Itatu ya Miniature Circuit Breaker:

Mtundu B (maulendo pa nthawi 3-5 yamagetsi ovotera).
Mtundu C (maulendo opitilira nthawi 5-10).
Mtundu D (maulendo opitilira nthawi 10-20).
