Otseka Ma Circuit: Alonda a Chitetezo cha Magetsi

KumvetsetsaZosokoneza DeraZipangizo Zofunika Kwambiri Zotetezera mu Machitidwe Amagetsi

Mu dziko la uinjiniya wamagetsi ndi chitetezo chapakhomo, mawu oti "circuit breaker" amapezeka nthawi zambiri. Circuit breaker ndi chipangizo chofunikira chomwe chimapangidwa kuti chiteteze ma circuit amagetsi ku kuwonongeka komwe kumachitika chifukwa cha kuchuluka kwa ma circuit kapena ma short circuit. Mwa kusokoneza kayendedwe ka magetsi pokhapokha ngati vuto lapezeka, ma circuit breaker amachita gawo lofunikira pakuwonetsetsa kuti makina amagetsi ndi otetezeka komanso ogwira ntchito bwino m'nyumba, m'mabizinesi, komanso m'mafakitale.

Kodi chosokoneza mawaya n'chiyani?

Chotsekereza magetsi ndi chosinthira magetsi chomwe chimatsegula kapena kutseka magetsi pansi pa mikhalidwe yabwinobwino komanso yolakwika. Mosiyana ndi fuse, yomwe iyenera kusinthidwa ikaphulika, chotsekereza magetsi chimatha kubwezeretsedwanso ikagwedezeka, zomwe zimapangitsa kuti ikhale njira yosavuta komanso yokhazikika yotetezera magetsi. Amabwera m'mitundu yosiyanasiyana ndi kukula kuti akwaniritse zosowa za ntchito zosiyanasiyana.

Mitundu ya ma circuit breakers

Pali mitundu ingapo ya ma circuit breaker, iliyonse ili ndi ntchito yakeyake:

1. Miniature Circuit Breaker (MCB): Ma circuit breaker amenewa amagwiritsidwa ntchito kwambiri m'nyumba ndi m'mabizinesi kuti ateteze ku overloads ndi short circuits. Ma MCB amapangidwira kuti azingogwedezeka okha pamene power ipitirira mulingo wokhazikika.

2. Zotsalira Zamagetsi Zamagetsi (RCCB): Zotsalira Zamagetsi izi, zomwe zimadziwikanso kuti RCDs (Zida Zamagetsi Zamagetsi Zamagetsi), zimapangidwa kuti zipewe kugwedezeka kwa magetsi pozindikira kusalingana kwa magetsi. Ngati vuto lachitika, monga munthu wokhudza waya wamoyo, RCCB idzagwa, ndikudula magetsi.

3. Chothyola Mphamvu Yotayira Madzi (ELCB): Mofanana ndi RCCB, ELCB imagwiritsidwa ntchito kuzindikira zolakwika za nthaka ndikupewa kugwedezeka kwa magetsi. Ndikofunikira kwambiri m'malo onyowa, monga m'bafa ndi m'khitchini.

4. Zothyola Mpweya (ACB): Zothyola mpweya zimenezi zimagwiritsidwa ntchito pamagetsi amphamvu kwambiri ndipo zimatha kuthana ndi mafunde amphamvu kwambiri. Ma ACB amagwiritsidwa ntchito kwambiri m'mafakitale ndipo amapangidwira kuteteza makina akuluakulu amagetsi.

5. Ma Hydraulic Magnetic Circuit Breakers: Ma circuit breakers amenewa amagwiritsa ntchito njira zosiyanasiyana za hydraulic ndi electromagnetic kuti adule circuit. Nthawi zambiri amagwiritsidwa ntchito m'ma system akuluakulu amagetsi omwe amafunika kuyendetsedwa bwino.

Momwe ma circuit breaker amagwirira ntchito

Ma circuit breaker amagwira ntchito pozindikira overcurrent. Pamene current ikuyenda mu circuit ikuposa mphamvu yovomerezeka ya circuit breaker, imayambitsa makina omwe amatsegula circuit, motero amaletsa kuyenda kwa current. Izi zitha kuchitika pazifukwa zingapo, monga short circuit, overload circuit, kapena malfunction mu system yamagetsi.

Njira yoyendera ingakhale yotentha, ya maginito, kapena kuphatikiza ziwirizi. Ulendo woyendera umagwiritsa ntchito mzere wa bimetallic womwe umapindika ukatenthedwa ndi mphamvu yowonjezera, pomwe ulendo woyendera maginito umagwiritsa ntchito maginito amagetsi omwe amagwira ntchito pamene mphamvuyo yapitirira malire enaake.

Kufunika kwa Ophwanya Dera

Kufunika kwa ma circuit breaker sikuyenera kunyalanyazidwa. Ndi ofunikira kwambiri popewa moto wamagetsi, kuteteza zipangizo zamagetsi ndi zida kuti zisawonongeke, komanso kuonetsetsa kuti munthu ali otetezeka. M'nyumba, ma circuit breaker ndi njira yoyamba yodzitetezera ku zoopsa zamagetsi, zomwe zimathandiza eni nyumba kuti ayambitsenso makinawo mwachangu akangoyenda.

Kuphatikiza apo, ma circuit breaker amathandiza kukonza magwiridwe antchito amagetsi. Mwa kupewa kuchuluka kwa magetsi, ma circuit breaker amathandiza kusunga umphumphu wa zomangamanga zamagetsi, kuchepetsa chiopsezo cha kukonza kokwera mtengo komanso nthawi yogwira ntchito.

MFUNDO YAPAMWAMBA

Pomaliza, ma circuit breaker ndi gawo lofunika kwambiri pamagetsi amakono. Ndi ofunikira pa chitetezo cha nyumba, mabizinesi, ndi malo opangira mafakitale chifukwa amaletsa kudzaza kwambiri ndi ma short circuit. Kumvetsetsa mitundu yosiyanasiyana ya ma circuit breaker ndi ntchito zawo kungathandize anthu kupanga zisankho zolondola pankhani ya chitetezo chamagetsi ndi kukonza. Pamene ukadaulo ukupitirirabe kusintha, ma circuit breaker mosakayikira adzakhala ndi gawo lofunika kwambiri mtsogolo mwa uinjiniya wamagetsi ndi chitetezo.
