• Mwa njira yolumikizira: kulumikizana kwa bolodi lakutsogolo, kulumikizana kwa bolodi lakumbuyo la b, mtundu wa pulogalamu yowonjezera ya c
• Pogwiritsa ntchito njira yogwirira ntchito: ntchito yogwirira mwachindunji, ntchito yogwirira yozungulira b, ntchito yamagetsi c
• Chiwerengero cha ndodo: 1P, 2P, 3P, 4P
• Ndi chowonjezera: kukhudzana ndi alamu, kukhudzana kothandizira, kutulutsidwa kwa shunt, kutulutsidwa kwa mphamvu yamagetsi

Mkhalidwe Wabwinobwino wa Utumiki

• Kutalika kwa malo okhazikitsa sikuyenera kupitirira 2000m
• Kutentha kwa mpweya wozungulira
• Kutentha kwa mpweya wozungulira sikuyenera kupitirira +40℃
• Mtengo wapakati suyenera kupitirira +35℃ mkati mwa maola 24
• Kutentha kwa mpweya wozungulira sikuyenera kuchepera -5℃
• Mkhalidwe wa mlengalenga:
• 1. Chinyezi cha mpweya sichiyenera kupitirira 50% pa kutentha kwakukulu kwa +40℃, ndipo chikhoza kukhala kutentha kwakukulu pa kutentha kochepa, pamene kutentha kotsika kwambiri pamwezi wonyowa kwambiri sikupitirira 25℃ kungakhale 90%, chifukwa cha kusintha kwa kutentha, ziyenera kuganiziridwa.
• Mlingo wa kuipitsa ndi kalasi 3

Kodi DC MCCB ndi chiyani?

Kumvetsetsa DC MCCB: Buku Lophunzitsira

Mu gawo la uinjiniya wamagetsi ndi kugawa mphamvu, mawu oti "MCCB" amapezeka kawirikawiri. MCCB imayimira Molded CaseChotsegula Derandipo ndi gawo lofunika kwambiri poteteza ma circuit ku overcurrent, short circuit ndi zina zolakwika zamagetsi. Ngakhale ma AC MCCB amakambidwa kwambiri, ma DC MCCB ndi ofunikiranso, makamaka pakugwiritsa ntchito ma direct current (DC) systems. Blog iyi cholinga chake ndi kufotokoza bwino ma DC molded case circuit breakers ndikukambirana za ntchito zawo, ma application awo ndi ubwino wawo.

Kodi chotsukira ma circuit cha DC molded case ndi chiyani?

Chosweka cha DC Molded Case Circuit Breaker (DC MCCB) kapena Chosweka cha DC Molded Case Circuit Breaker ndi chosweka cha circuit chopangidwa mwapadera kuti chiteteze ma DC circuits. Mosiyana ndi ma AC ena, ma DC MCCB amapangidwira kuthana ndi mavuto apadera omwe DC imabweretsa, monga kusowa kwa malo odulira zero komanso kuthekera kodulira nthawi zonse. Ma circuit breaker awa ndi ofunikira m'mafakitale osiyanasiyana, kuphatikizapo mphamvu zongowonjezwdwanso, mayendedwe ndi mauthenga, omwe nthawi zambiri amagwiritsa ntchito magetsi a DC.

Kodi chotsukira ma circuit cha DC molded case chimagwira ntchito bwanji?

Ntchito yayikulu ya DC molded case circuit breaker ndikusokoneza magetsi ngati magetsi achulukirachulukira kapena afupikitsa. Nayi njira yofotokozera momwe imagwirira ntchito:

1. Kuzindikira: Chotsukira magetsi chopangidwa ndi DC chimayang'anira nthawi zonse magetsi omwe akuyenda mu dera. Ngati magetsi apitirira mphamvu yovomerezeka ya chotsukira magetsi, njira yotetezera imayambitsidwa.

2. Kusokoneza: Pamene magetsi akuchulukirachulukira apezeka, chosokoneza magetsi chimatsegula zolumikizira zake kuti chisokoneze kayendedwe ka magetsi. Izi zimaletsa kuwonongeka kwa magetsi ndi zida zolumikizidwa.

3. Kuzimitsa Arc: Chimodzi mwa zovuta zazikulu mu machitidwe a DC ndi kupanga ma arc. Pamene ma contacts atsegulidwa, arc imapangidwa chifukwa cha kupitiliza kwa DC current. Ma DC molded case circuit breakers ali ndi njira zozimitsira arc, monga zipinda zozimitsira arc kapena zida zozimitsira arc zamaginito, kuti achotse ma arc mosamala.

4. Konzaninso: Pambuyo poti vuto latha, chodulira mawaya chikhoza kubwezeretsedwanso pamanja kapena chokha kuti chiyambenso kugwira ntchito bwino.

Zinthu zazikulu za DC molded case circuit breaker

Ma DC molded case circuit breakers ali ndi zinthu zingapo zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ndi DC:

- Kutha Kuthyola Kwambiri: Amapangidwira kuti azitha kuthana ndi mafunde amphamvu, kuonetsetsa kuti chitetezo chodalirika ngakhale m'malo ovuta.
- Ma Units Oyendera Kutentha ndi Magnetic: Ma Units awa amapereka chitetezo chawiri poyankha ku overcurrent yayitali (thermal) ndi short circuit ya kanthawi (magnetic).
- Zosintha Ulendo: Ma DC MCCB ambiri amapereka zosinthika ulendo, zomwe zimathandiza kusintha malinga ndi zofunikira zinazake.
- Kapangidwe Kakang'ono: Kapangidwe ka nyumba yopangidwa ndi ulusi kamatsimikizira mawonekedwe ake opapatiza komanso olimba, zomwe zimapangitsa kuti zikhale zosavuta kuphatikiza m'njira zosiyanasiyana.

Kugwiritsa Ntchito DC Molded Case Circuit Breaker

Ma DC molded case circuit breakers amagwiritsidwa ntchito kwambiri m'mafakitale ndi zochitika zosiyanasiyana:

- Mphamvu Zobwezerezedwanso: Makina amphamvu a dzuwa, ma turbine amphepo ndi makina osungira mphamvu nthawi zambiri amagwiritsa ntchito ma DC molded case circuit breakers kuti ateteze ma circuit awo.
- Magalimoto Amagetsi (EV): Ma DC molded case circuit breakers amagwiritsidwa ntchito m'malo ochajira magalimoto amagetsi ndi machitidwe omwe ali mkati mwa galimoto kuti atsimikizire kuti ntchito yawo ndi yotetezeka.
- Kulankhulana: Zomangamanga zolumikizirana zomwe zimadalira kwambiri mphamvu ya DC zimagwiritsa ntchito ma circuit breakers awa kuteteza zida zofunika kwambiri.
- Zodzichitira Pang'onopang'ono Zamakampani: Ma DC Molded Case Circuit Breakers amagwiritsidwa ntchito m'mafakitale osiyanasiyana pogwiritsa ntchito ma DC motors ndi ma drive.

Ubwino wogwiritsa ntchito ma DC molded case circuit breakers

- Chitetezo Chowonjezereka: Zothyola ma circuit breaker za DC molded zimawonjezera chitetezo cha machitidwe amagetsi ndi antchito mwa kupereka chitetezo chodalirika cha overcurrent ndi short circuit.
- KUCHEPETSA NTHAWI YOGWIRA NTCHITO: Kulephera kugwira ntchito mwachangu kumachepetsa kuwonongeka ndi kuchepetsa nthawi yogwirira ntchito, zomwe zimapangitsa kuti machitidwe ofunikira azigwira ntchito mosalekeza.
- Yotsika Mtengo: Kuteteza kuwonongeka kwa zida zodula ndikuchepetsa ndalama zokonzera, zomwe zimapangitsa kuti ma DC Molded Case Circuit Breakers akhale njira yotsika mtengo.

Powombetsa mkota

Chotsekereza magetsi chopangidwa ndi DC ndi chinthu chofunikira kwambiri m'makina amagetsi amakono, chomwe chimapereka chitetezo champhamvu ndikuwonetsetsa kuti ma DC circuits akugwira ntchito bwino. Kumvetsetsa ntchito zake, mawonekedwe ake, ndi momwe amagwiritsidwira ntchito kungathandize mainjiniya ndi akatswiri kupanga zisankho zodziwa bwino popanga ndi kusamalira makina amagetsi a DC. Pamene kufunikira kwa magetsi ongowonjezedwanso ndi magalimoto amagetsi kukupitilira kukula, kufunika kwa ma DC circuits opangidwa ndi DC kudzangowonjezeka, zomwe zimapangitsa kuti zikhale gawo lofunikira kwambiri pa zomangamanga zathu zamagetsi.
