Mitundu ya Circuit Breaker ndi Buku Lothandizira

KumvetsetsaZosokoneza DeraZipangizo Zofunika Kwambiri Zotetezera mu Machitidwe Amagetsi

Mu dziko la uinjiniya wamagetsi ndi chitetezo chapakhomo, mawu oti "circuit breaker" amamveka kwambiri. Circuit breaker ndi chipangizo chofunikira chomwe chimapangidwa kuti chiteteze ma circuit amagetsi ku zinthu zambiri komanso ma short circuit, kuonetsetsa kuti ma electronic system ndi omwe amagwiritsa ntchito ndi otetezeka. Nkhaniyi ikufotokoza mozama za 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 chimasokoneza kayendedwe ka magetsi mu dera chikazindikira vuto linalake, monga kudzaza kwambiri kapena kufupika kwa magetsi. Mosiyana ndi ma fuse, omwe ayenera kusinthidwa akaphulika, ma circuit breaker amatha kubwezeretsedwanso akagwa, zomwe zimapangitsa kuti akhale njira yabwino komanso yotetezeka yamagetsi. Nthawi zambiri amaikidwa m'mapanelo amagetsi ndipo ndi ofunikira popewa moto wamagetsi ndi kuwonongeka kwa zida.

Kodi ma circuit breaker amagwira ntchito bwanji?

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

1. Njira yotenthetsera: Njirayi imagwiritsa ntchito chingwe cha bimetallic chomwe chimatentha ndikupindika pamene mphamvu yamagetsi ili yokwera kwambiri. Chingwe cha bimetallic chikapindika pamlingo winawake, chimayambitsa chotsegula ma circuit kuti chitseguke, zomwe zimasokoneza dera.

2. Kachitidwe ka maginito: Kachitidwe kameneka kamadalira mphamvu ya maginito. Pamene dera lalifupi la magetsi lachitika, mphamvu yamagetsi yadzidzidzi imapanga mphamvu ya maginito yokwanira kukoka lever, motero kuswa dera.

Ma circuit breaker ena amakono amaphatikiza njira zonse ziwiri kuti atetezedwe bwino ndipo amadziwika kuti ma circuit breaker a "dual function".

Mitundu ya ma circuit breakers

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

1. Ma Circuit Breaker Okhazikika: Awa ndi ma circuit breaker odziwika kwambiri omwe amapezeka m'nyumba zogona komanso zamabizinesi. Amateteza ku overload ndi short circuit.

2. Ground Fault Circuit Interrupter (GFCI): Ma circuit breaker awa adapangidwa kuti ateteze ku zolakwika za nthaka, zomwe zimachitika pamene magetsi akutuluka kuchokera ku dera lomwe akufuna. Ma GFCI nthawi zambiri amagwiritsidwa ntchito m'malo onyowa monga m'bafa ndi m'khitchini.

3. Arc Fault Circuit Interrupter (AFCI): AFCIs amapangidwira kuzindikira zolakwika za arc zomwe zingayambitse moto wamagetsi. Ndi othandiza kwambiri m'zipinda zochezera ndi m'zipinda zogona.

4. Ma Miniature Circuit Breakers (MCBs): Ma circuit breakers awa amagwiritsidwa ntchito pamagetsi otsika ndipo amapangidwira kuti agwe pamagetsi enaake.

5. Chipangizo Chotsalira cha Mphamvu (RCD): Mofanana ndi GFCI, RCD imaletsa kugwedezeka kwa magetsi mwa kuzindikira kusalinganika kwa mphamvu.

Kufunika kwa Ophwanya Dera

Kufunika kwa ma circuit breaker sikuyenera kunyalanyazidwa. Ndiwo mzere woyamba wodzitetezera ku ngozi zamagetsi. Mwa kuzimitsa magetsi okha panthawi yamavuto, ma circuit breaker amathandiza kupewa moto wamagetsi, kuwonongeka kwa zida, ndi kuvulala kwa anthu.

Kuphatikiza apo, ma circuit breaker amathandiza kukonza magwiridwe antchito amagetsi. Amayendetsa bwino katundu wamagetsi, kuonetsetsa kuti ma circuit akugwira ntchito moyenera momwe adapangidwira. Izi sizimangowonjezera nthawi ya zida zamagetsi, komanso zimachepetsa kuwononga mphamvu.

MFUNDO YAPAMWAMBA

Pomaliza, ma circuit breaker ndi gawo lofunika kwambiri pamagetsi amakono. Ndi ofunikira pa chitetezo cha nyumba ndi mabizinesi chifukwa amaletsa kudzaza kwambiri, ma short circuit, ndi zolakwika zina zamagetsi. Kumvetsetsa mitundu yosiyanasiyana ya ma circuit breaker ndi ntchito zawo kungathandize anthu kupanga zisankho zolondola zokhudza magetsi awo, zomwe pamapeto pake zimawonjezera chitetezo ndi magwiridwe antchito. Pamene ukadaulo ukupitirirabe kusintha, ma circuit breaker mosakayikira adzakhala ndi gawo lofunika kwambiri pa tsogolo la chitetezo chamagetsi.
