Kodi mfundo yogwiritsiridwa ntchito ya circuit breaker ndi iti?

Mfundo yogwira ntchito ya awowononga deraimazungulira mfundo zazikuluzikulu zowunikira, kuweruza, ndi kachitidwe. Kupyolera mu makina ake omangirira mkati ndi makina ozimitsa arc, imakwaniritsa kulumikizana kwanthawi zonse ndikuwongolera kulumikizidwa komanso kusokoneza mwachangu mabwalo olakwika. Mwachindunji, imatha kugawidwa m'machitidwe abwinobwino komanso chitetezo cha zolakwika. Dongosolo lozimitsira arc ndi njira yofunikira yothandizira kuwonetsetsa kuyenda modalirika.

Dera likakumana ndi zolakwika monga kulemedwa, kufupika, kapena kutsika kwamphamvu, gawo lolowera mkati limayambitsa makina otsekera kuti atseguke, ndikungodumpha. Zolakwika zosiyanasiyana zimayenderana ndi mfundo zosiyanasiyana zodumphira:

Chitetezo Chowonjezera Kwambiri (Mfundo Yoyendera Matenthedwe)

Core Component: Bimetallic strip (yopangidwa ndi mapepala awiri achitsulo okhala ndi ma coefficients osiyana kwambiri a kukulitsa kwamafuta ophatikizidwa pamodzi).

Zolinga Zogwirira Ntchito: Dera likadzaza kwambiri, zomwe zikuchitika zimapitilira mtengo wake, zomwe zimapangitsa kuti mzere wa bimetallic upindike ndikupunduka chifukwa cha kutentha. Ma deformation akafika pachimake, amakankhira njira yotsekera kuti atsegule, ndipo kukhudzana kosuntha kumaswa dera pansi pakuchita masika.

Mbali: Kuchedwa kuchitapo kanthu; Kuchulukitsitsa kwakanthawi kochepa (monga kuyambitsa injini) sikungayambitse kupunthwa, kupewa kupunthwa kwabodza.

Chitetezo Chachifupi Chozungulira (Mfundo Yoyendera ya Electromagnetic)

Chigawo Chapakati: Koyilo yamagetsi yamagetsi (chilonda chozungulira pakati pachitsulo).

Malingaliro Ogwiritsa Ntchito: Pamene dera lalifupi lichitika, zomwe zikuchitikazi zimakwera nthawi yomweyo kufika makumi kapena mazana nthawi zambiri za mtengo wake. Koyilo yamagetsi imapanga mphamvu yamphamvu yamagetsi, kukopa pachimake chachitsulo kuti igunde makina otsekera, ndikutsegula nthawi yomweyo.

Mawonekedwe: Kuchita mwachangu kwa Millisecond-level, kutha kudula dera munthawi yochepa kwambiri, kupewa kuwotcha kwa arc ku zida kapena kuyambitsa moto.

Kutetezedwa kwa Undervoltage/Kutayika kwa Voltage (Mfundo Yoyendera Pansi pa Voltage)

Core Component: Koyilo yapaulendo ya Undervoltage, yolumikizidwa molumikizana mozungulira kuti iwunikire voteji.

Malingaliro Ogwiritsa Ntchito: Mphamvu yamagetsi ikatsika pansi pafupifupi 70% ya mtengo wake kapena kutayika kwathunthu, mphamvu yamagetsi yapaulendo imasowa, ndipo pachimake chachitsulo, pochita masika, imayambitsa makina otsekera kuti atsegule, kudula dera.

Ntchito: Imateteza zida kuti zisagwire ntchito molakwika komanso kuwonongeka pansi pamagetsi otsika, ndikupewa ngozi yomwe imabwera chifukwa choyambitsa zida mwadzidzidzi mphamvu ikabwezeretsedwa.

Chitetezo cha Kutayikira (Mfundo Yotsalira Yatsopano Yachitetezo)

Core Component: Zero-sequence current transformer.

Malingaliro Ogwiritsa Ntchito: Nthawi zonse, mafunde omwe ali mugawo ndi mizere yopanda ndale amakhala ofanana kukula kwake komanso kosiyana molunjika. Kuthamanga kwa maginito mu transformer core kumalepheretsana, zomwe zimapangitsa kuti pasakhale kutulutsa komweku. Pamene kutayikira kumachitika (monga kugwedezeka kwa magetsi), madzi ena amatayika pansi, zomwe zimapangitsa kusalinganika kwa mafunde a magawo awiri. Transformer imapanga chizindikiro chochititsa chidwi, ndikuyambitsa gawo laulendo.

Mawonekedwe: Malo ocheperako (nthawi zambiri 30mA), kuyika patsogolo chitetezo chamunthu.
