Kutentha ndi Magetsi a MCCB a Machitidwe Amphamvu Zamakampani: Ndi Yabwino Kwambiri?

Kodi munayamba mwafufuzapo mozama pamene Ulendo Wotsegula DeraKodi palibe chifukwa? Kodi chitetezo chamagetsi choyenera chalephera kugwira ntchito panthawi yoyenera, kapena mwapeza kuti ma circuit breaker anu akulephera kugwira ntchito msanga? Ngati mwakumanapo ndi chimodzi mwa izi, muyenera kudzifunsa ngati mtundu wa MCCB wanu ukugwirizana ndi malo omwe mumagwira ntchito.

Ambiri mwa MCCBs (Mlanduwu Wopangidwa Chotsegula Deras)pamsika masiku ano ndi maginito otenthetsera MCCBzomwe zimapereka chitetezo chokwanira kuti zisagwedezeke pa ntchito za m'nyumba ndi zamalonda; komabe, m'malo otsatirawa a mafakitale, mafakitale, mabwalo owongolera magalimoto, malo ochitira masewera olimbitsa thupi otentha kwambiri, ndi ntchito zamagetsi obwezerezedwanso, maginito otenthetsera kutentha MCCB malire amamveka bwino. Apa ndi pomwe kugwiritsa ntchito kalembedwe ka maginitomatiki koyera MCCBs (monga ELM1 electromagnetic) imakhala yogwira ntchito kwambiri; Magetsi oyera MCCBs amapereka mayankho ku mavuto ambiri omwe ali mumakina amagetsi amafakitale.

Nkhaniyi ikupatsani mwachidule kusiyana pakati pa Kutentha-Maginito MCCB ndi Woyera MCCB yamagetsi, momwe chilichonse chimagwiritsidwira ntchito, ndi chifukwa chake ndikofunikira kusankha yoyenera MCCB m'malo amakono a mafakitale.

Kodi MCCB Yotentha-Maginito Ndi Chiyani?

The Kutentha-Maginito MCCB ndi MCB yomwe imagwiritsidwa ntchito kwambiri ndipo ili ndi mitundu iwiri ya chitetezo: chitetezo chopitirira muyeso ndi chitetezo cha short-circuit.

• Chitetezo Chodzaza Zinthu:Izi zimachitika kudzera mu mzere wa bimetallic. Pamene mzere wa bimetallic iyeinde Mukakwera kuchokera ku mphamvu yamagetsi yochuluka yomwe ikuyenda mkati mwake, imapindika kuchoka pa dera, zomwe zimapangitsa kuti chala chigwe; izi zimadziwika kuti chitetezo cha overload.
• Chitetezo cha Dera Lalifupi: Dera loteteza mafunde afupi limaperekedwa ndi coil yamagetsi. Coil yamagetsi imalandira mphamvu pamene mphamvu zambiri zikuyenda mu dera (laufupi). Mphamvu ya maginito yopangidwa ndi coil imapangitsa kuti chopasula chigwe nthawi yomweyo; chitetezo ichi chimatchedwa chitetezo cha mafunde afupi.

Kugwira ntchito kwa MCCB yotenthetsera ndi maginito ndikosavuta - pamene bimetallic strip itenthedwa ndi mphamvu yamagetsi yochuluka yomwe ikuyenda mu bimetallic strip, bimetallic strip imapindika ndikutseguka kuti igwetse breaker panthawi yodzaza; coil yamagetsi imatsegula breaker mkati mwa nthawi yochepa kwambiri panthawi yamagetsi olemera afupikitsa.

Vuto lalikulu la makina oteteza kutentha ndilakuti amadalira kusintha kwa kutentha kuti ateteze ku zinthu zochulukirachulukira—monga, makina oteteza kutentha amadalira kutentha.

Kodi MCCB Yoyera ya Magetsi ndi Chiyani?

MCCB yoyera yamagetsi sigwiritsa ntchito chingwe cha kutentha cha bimetal kuti chiteteze ku zinthu zodzaza ndi magetsi komanso zofupikitsa monga TC-MCCB. M'malo mwake, zokonzera maulendo a MCCB zimadalira kokha kulowetsedwa kwa magetsi ndipo sizidalira mphamvu ya kutentha kuti ziteteze ku zinthu zodzaza ndi magetsi kapena zofupikitsa.

2. Kusinthasintha kwa Katundu wa Magalimoto

Ma injini ambiri ogwira ntchito m'mafakitale amapanga mafunde olowera (mpaka nthawi 3-5 kuposa mphamvu yoyesedwa) omwe ndi okwera kuposa masiku onse akamayatsa. MCCB yomwe sikugwira ntchito bwino iyenera kusiyanitsa pakati pa kuwonjezeka kwakanthawi ndi zolakwika zenizeni mu mphamvu.

Zophulitsira Maginito ndi Kutentha: Ma breaker amenewa nthawi zambiri salabadira kwambiri kusintha kwa mphamvu yamagetsi, chifukwa ambiri molakwika amaika kusintha kwa injini ndi overload. Izi zimapangitsa kuti breaker igwedezeke mobwerezabwereza, zomwe zingasokoneze ntchito yake motero kuchepetsa kugwira ntchito bwino.

Zophulitsira Magetsi Zoyera: Ma breaker awa adapangidwa makamaka kuti agwiritsidwe ntchito pa injini ndipo motero ali ndi ukadaulo wapamwamba wozindikira mphamvu yamagetsi kuti asiyanitse kuthamanga kwa injini ndi kuchuluka kwenikweni kwa mphamvu. Izi zimawathandiza kugwira ntchito mofanana mu ntchito zomwe nthawi zambiri zimaphatikizapo kuyambitsa injini.

3. Kuyankha Kolakwika ndi Kulondola kwa Chitetezo

Kuti muchepetse kuwonongeka kwa zida zamagetsi zofunika kwambiri, luso lotha kuzindikira ndikugwetsa cholakwika mwachangu ndilofunika kwambiri.

Zophulitsira Ma Circuit Zotentha ndi Maginito: Amachedwetsa nthawi pogwetsa cholakwika, chifukwa chitetezo chawo cha kutentha kwambiri chimapangidwa potenthetsa chingwe cha bimetallic ndikuwononga chingwecho. Chifukwa chake, kuthekera komva nthawi yomweyo kukwera kwa mphamvu yamagetsi kumakhala kochepa ndi mtundu uwu wa chosweka, zomwe zimapangitsa kuti zida ziwonongeke kwambiri.

Zophulitsira Zamagetsi Zamagetsi Zoyera: Kutengera mfundo za kulowetsa magetsi m'magetsi, ma electromagnetic circuit breaker okha ali ndi ma circuit omwe amagunda nthawi yomweyo omwe amatha kuyankha kufupika kwa magetsi komanso kupitirira muyeso mkati mwa ma microseconds. Chifukwa chake, mtundu uwu wa circuit breaker umachotsa cholakwika mwachangu, motero kuchepetsa chiopsezo cha kuwonongeka kwa injini, chingwe, ndi zida zina zomvera.

4. Kudalirika kwa Ntchito Kwa Nthawi Yaitali

Ma circuit breaker omwe amagwiritsidwa ntchito m'mafakitale amafunika kugwira ntchito moyenera pakapita nthawi ndikupereka magwiridwe antchito opitilira ngakhale kuti amawonongeka pogwiritsa ntchito tsiku ndi tsiku.

Zophulitsira Ma Circuit Zotentha ndi Maginito: Chifukwa cha kutentha kwambiri ndi kuzizira, mipiringidzo ya bimetallic imatopa kwambiri, zomwe zimakhudza kulondola kwa ulendo pakapita nthawi. Zosokoneza ma circuit nthawi zina zimayambitsa maulendo osafunikira komanso kulephera kugwa bwino.

Ma MCCB Oyera a Magetsi: Chotsukira maginito cha mtundu wa ELM1 electromagnetic type MCCB (molded case circuit breaker) sichidzawonongeka ndi kutentha kwambiri chifukwa cha kutentha. Palibe zigawo za kutentha zomwe zingachepetse kulondola kwawo; chifukwa chake, zidzakhala ndi makhalidwe olondola opunthwa pa moyo wawo wonse, zomwe zapangidwa kuti zipereke maginito osachepera 125,000 asanakonze kapena kusintha zida zina.

Kodi Muyenera Kusankha Liti Electromagnetic MCCB?

Ma MCCB amagetsi oyera si abwino kwambiri m'malo omwe anthu amawafuna kwambiri monga m'nyumba kapena m'malo osungiramo katundu; komabe, ma MCCB amagetsi ndi ofunika kwambiri m'mafakitale otsatirawa:
