Miniature Circuit Breakers: Kusunga Chitetezo Chanu Chozungulira

Chidule

Chotsekera chaching'ono cha MCBndi AC yotsika mphamvu zambirichosokoneza dera, yokhala ndi overload, short circuit, undervoltage komanso mphamvu yamphamvu yosweka.

1. Makhalidwe a kapangidwe kake

• Imapangidwa ndi njira yotumizira mauthenga ndi njira yolumikizirana;
• Njira zotumizira zimagawidwa m'magulu awiri: zodziyimira zokha komanso zamanja;
• Pali mitundu iwiri ya machitidwe olumikizirana, imodzi ndi yolumikizirana yachikhalidwe, inayo ndi yolumikizirana ndi makina ogwiritsira ntchito masika osinthika.

2. Kagwiridwe ka ntchito kaukadaulo

• Ili ndi makhalidwe monga kupitirira muyeso, kufupika kwa magetsi, kusakhala ndi mphamvu zamagetsi komanso mphamvu yosweka yamphamvu;
• Ili ndi mawonekedwe odalirika komanso otseguka kwa nthawi yayitali.

3. Malamulo ogwiritsira ntchito

• Njira yokhazikitsira: kukhazikitsa kokhazikika, kukhazikitsa kwa flange;
• Njira yotetezera kutentha: mitengo itatu;
• Yoyenera AC 50Hz, voteji yoteteza kutentha ndi 630V ~ 690V, mphamvu yamagetsi ndi 60A ~ 1000A.

Kukula kwa Ntchito

MCBzodulira zazing'ono za deraamagwiritsidwa ntchito makamaka polowera ndi potulukira maukonde osiyanasiyana ogawa, makamaka kuphatikiza:

• Dongosolo logawa magetsi.
• Imagwira ntchito pa makina ogawa magetsi ngati chitetezo cha mizere yodzaza ndi kupitirira muyeso komanso kufupika kwa magetsi;
• Imagwira ntchito pa mitundu yonse ya chitetezo cha injini poyambira ndi kuletsa mabuleki.
• Imagwira ntchito poyang'anira njira zamagetsi zomwe zimagwiritsidwa ntchito, monga magetsi, wailesi yakanema, foni ndi kompyuta;
• Imagwira ntchito ku malo omwe sasinthidwa kawirikawiri kapena kugwiritsidwa ntchito m'magawo.
• Amagwiritsidwa ntchito makamaka poteteza mzere (chitetezo cha overcurrent), ndipo amapereka chitetezo chodula mwachangu fault current chifukwa cha short-circuit fault mu circuit;
• Ikhoza kugwiritsidwa ntchito ngati zida zoyambira injini ndi zotsekera mabuleki;
• Itha kugwiritsidwa ntchito poteteza zida zamagetsi mopitirira muyeso komanso mwachangu;
• Ingagwiritsidwe ntchito kuteteza mota ndi transformer ku overload ndi undervoltage.

Mikhalidwe Yogwiritsira Ntchito

• 1, Kutentha kwa mpweya wozungulira sikuyenera kupitirira + 40 ℃, ndipo sikuyenera kupitirira - 5 ℃, chinyezi chaching'ono sichiyenera kupitirira 90%, ndipo chinyezi chaching'ono chimaloledwa pa kutentha kotsika;
• 2, kutentha kwa mpweya wozungulira sikuyenera kupitirira + 40 ℃;
• 4, Kukwera kwa malo okhazikitsa sikuyenera kupitirira 2000m;
• 5, Mu sing'anga yopanda chiopsezo cha kuphulika, ndipo mu sing'anga mulibe mpweya kapena nthunzi yokwanira kuwononga zitsulo ndikuwononga kutchinjiriza;
• 6, Palibe kugwedezeka kwamphamvu, kukhudzidwa kapena kusintha pafupipafupi.
• 9, Chotsekera dera ndi chipangizo chokhazikitsira pansi zitha kuyikidwa ndikulumikizidwa malinga ndi malangizo a wopanga kapena zomwe zafotokozedwa mu malonda;
• 10, Chotsekera ma circuit chingagwiritsidwe ntchito pamodzi ndi zoteteza kutayikira kwa pole imodzi ndi pole zambiri zomwe zayikidwapo kuti apange chipangizo choteteza kutayikira kwa pole chophatikizika.

Kukhazikitsa Mawaya ndi Zosamala

1. Malo okhazikitsa:

Kutentha kwa mpweya wozungulira kuyenera kukhala kuyambira -5 ℃ mpaka +40 ℃, nthawi zambiri sikuyenera kupitirira +35 ℃; kutentha kwapakati pa maola 24 sikuyenera kupitirira +35 ℃, ndipo chinyezi cha mpweya wozungulira sichiyenera kupitirira 50%.

2. Malo oyika:

Pamene chotsegula magetsi chaikidwa pambali yolowera magetsi, mapeto a switch a chotsegula magetsi ayenera kukhala olimba, ndipo kukana kwa insulation pakati pa chotsegula magetsi ndi chimango chachitsulo chokhazikika kuyenera kukhala koposa 1000MΩ;

Pamene chotsegula magetsi chayikidwa mbali ya magetsi, sichingakhazikike pansi;

3. Malamulo ogwiritsira ntchito:

Chotsekera ma circuit chiyenera kuyikidwa pamalo oikirapo mopingasa kapena moyimirira. Ngati izi sizingakwaniritsidwe chifukwa cha malire a malo oikirapo, njira zotsatirazi zitha kutengedwa:

(1) Ma contact othandizira ayenera kukhazikitsidwa pamalo oyenera pa bolodi la terminal la wogulitsa wakale wa circuit breaker.

Kukhazikitsa kwapadera 3 ~ 4. Pamene chotsegula mawaya sichingagwire ntchito bwino, chikhoza kukhazikika bwino pogwiritsa ntchito kulumikizana kothandizira.
