Oteteza ma circuit oteteza: kuyang'anitsitsa udindo wofunikira wa ma circuit breaker ang'onoang'ono

Zosokoneza madera zazing'ono, nthawi zambiri amatchedwaMa MCB, ndi gawo lofunika kwambiri pamagetsi amakono. Ndi chipangizo chofunikira kwambiri chotetezera chomwe chimateteza ma circuit ku zinthu zodzaza ndi magetsi komanso ma circuit afupiafupi, zomwe zimateteza kuwonongeka kwa zipangizo zamagetsi ndi makina onse. Nkhaniyi ikambirana kufunika ndi udindo wazodulira zazing'ono za dera.

Chimodzi mwa ntchito zazikulu zaMCBndi kuyang'anira mphamvu yamagetsi yomwe ikuyenda kudzera mu dera ndikuyiyimitsa ngati pachitika vuto linalake. Imatsegula dera lokha, kusokoneza kayendedwe ka magetsi, motero kupewa kuwonongeka kulikonse komwe kungachitike. Mbali imeneyi ndi yofunika kwambiri popewa ngozi zamoto zomwe zimachitika chifukwa cha kutentha kwambiri kapena mavuto amagetsi.

Zosokoneza madera zazing'onoapangidwa kuti azitha kuthana ndi magetsi osiyanasiyana. Amapezeka m'magiredi osiyanasiyana, zomwe zimathandiza ogwiritsa ntchito kusankha magetsi oyenera.MCBmalinga ndi zosowa zawo. Ma rating awa nthawi zambiri amafotokozedwa mu ma amperes (A) ndipo amaimira mphamvu yayikulu yomwe ingadutse mu circuit breaker popanda kugwedezeka.

Njira yogwirira ntchito yachosokoneza dera chaching'onoimakhala ndi maginito amagetsi ndi chidutswa cha bimetallic. Pamene magetsi akuchulukirachulukira kapena kufupika kwafupika, mphamvu yamagetsi kudzera muMCBKupitirira malire ake apamwamba kwambiri. Izi zimapangitsa kuti bimetal ipinde chifukwa cha kutentha kwakukulu, zomwe pamapeto pake zimagwetsa dera. Pamene magetsi akuchulukirachulukira kapena afupikitsa dera, maginito amatseka nthawi yomweyo, kupereka chitetezo mwachangu komanso chodalirika.

Zosokoneza madera zazing'onoPali ubwino wambiri kuposa ma fuse achikhalidwe. Amatha kubwezeretsedwanso mosavuta akagwa, zomwe zimathandiza kuti pasakhale kufunikira kosintha nthawi iliyonse pomwe vuto lichitika. Kutha kubwezeretsa chosokoneza magetsi sikuti kumangopulumutsa nthawi komanso kumachepetsa ndalama zokonzera. Kuphatikiza apo,Ma MCBkupereka chitetezo cholondola komanso cholondola mwa kuzindikira ndikuyankha kusinthasintha kwamagetsi kwakanthawi kochepa munthawi yake.

Powombetsa mkota,zodulira zazing'ono za derandi gawo lofunika kwambiri la machitidwe amagetsi chifukwa amapereka chitetezo chogwira ntchito mopitirira muyeso komanso chofupikitsa magetsi. Kutha kwawo kuswa magetsi mwachangu kumathandiza kupewa ngozi zamagetsi ndikuwonetsetsa kuti anthu ndi zida zawo ndi otetezeka. Mwa kusankha mulingo woyenera, ogwiritsa ntchito amatha kusintha mulingo wa chitetezo chofunikira pamakina awo apadera amagetsi. Ponseponse, kuyika ndalama muubwinochosokoneza dera chaching'onondikofunikira kwambiri kuti chitetezo ndi kudalirika kwa makina aliwonse amagetsi zikhalebe zotetezeka.
