Miniature circuit breaker, yotchedwa MCB (Micro Circuit Breaker/ Miniature Circuit Breaker), ndiye chida chodzitetezera chomwe chimagwiritsidwa ntchito kwambiri pomanga zida zogawira magetsi.Amagwiritsidwa ntchito pa gawo limodzi ndi gawo laling'ono la magawo atatu, chitetezo chochulukira komanso chitetezo chopitilira 125A, kuphatikiza single-pole 1P, two-pole 2P, three-pole 3P, and four-pole 4P.

2. MotaniMCBNtchito?

 

Zowonongeka zazing'ono zimapangidwa ndi makina ogwiritsira ntchito, zolumikizirana, zida zodzitetezera (zotulutsa zosiyanasiyana), ndi zida zozimitsa za arc.Zolumikizira zake zazikulu zimayendetsedwa pamanja kapena kutsekedwa ndi magetsi.Pambuyo pa kukhudzana kwakukulu kutsekedwa, njira yaulere yaulendo imatseka kukhudzana kwakukulu pamalo otsekedwa.Coil ya kumasulidwa kwa overcurrent ndi chinthu chotenthetsera cha kumasulidwa kwa kutentha kumagwirizanitsidwa motsatizana ndi dera lalikulu, ndipo coil ya kumasulidwa kwa undervoltage imagwirizanitsidwa mofanana ndi magetsi.Pamene dera liri lalifupi kapena lolemedwa kwambiri, chida cha kumasulidwa kwa overcurrent chimakokedwa kuti apange njira yaulere yaulendo, ndipo kukhudzana kwakukulu kumadula dera lalikulu.Dongosolo likadzaza kwambiri, gawo lotenthetsera la kutulutsa kwamafuta limatenthetsa ndikupindika bimetal, ndikukankhira njira yotulutsa yaulere kuti igwire.Pamene dera likuphwanyidwa, mphamvu ya kumasulidwa kwa undervoltage imatulutsidwa.Yambitsaninso njira yaulere yaulendo

 

3.Cholinga chaMCB ?

 

M'mapangidwe omanga nyumba, zowononga magetsi otsika kwambiri zimagwiritsidwa ntchito kwambiri pakudzaza mizere, kufupikitsa, kupitilira apo, kutayika kwamagetsi, kutsika kwamagetsi, kuyika pansi, kutayikira, kusinthika kwamagetsi apawiri, chitetezo ndi magwiridwe antchito amagetsi munthawi yamagetsi. kuyambira pafupipafupi.Mfundo Zazikulu Kuphatikiza pa kutsata mfundo zoyambira monga momwe chilengedwe chimagwirira ntchito pazida zamagetsi zotsika mphamvu (onani Buku Lopanga Mapangidwe a Industrial and Civil Power Distribution Design), izi ziyenera kuganiziridwa:

1) Mphamvu yamagetsi yamagetsi yamagetsi yamagetsi sayenera kukhala yocheperako kuposa mphamvu yamagetsi;

2) Mawonekedwe amakono a wozungulira dera ndi momwe amachitira pakalipano ya kumasulidwa kwa overcurrent sikucheperapo kusiyana ndi chiwerengero chowerengedwa cha mzere;

3) Kuthamanga kwafupikitsa kwafupikitsa kwa wodutsa dera sikocheperapo kusiyana ndi kuchuluka kwafupipafupi komwe kuli pamzere;

4) Kusankhidwa kwa oyendetsa magetsi oyendetsa magetsi kuyenera kuganizira za kuchedwa kwakanthawi kochepa kwapang'onopang'ono komanso kulumikizana pakati pa chitetezo chochedwa;

5) Ma voliyumu ovoteledwa a kutulutsidwa kwa undervoltage kwa wowononga dera ndi ofanana ndi voliyumu ya mzere;

6) Ikagwiritsidwa ntchito poteteza mota, kusankha kwa wowononga dera kuyenera kuganizira momwe injiniyo imayambira ndikupangitsa kuti isagwire ntchito panthawi yoyambira;onani "Industrial and Civil Power Distribution Design Manual" powerengera mapangidwe;

7) Kusankhidwa kwa owononga dera kuyeneranso kuganizira za kusankhana kosankha kwa owononga dera ndi oyendetsa madera, ophwanya ma circuit ndi fuse.

   

4.Chifukwa chiyani Yueqing AIso?

4.1: Thandizo laukadaulo ndiukadaulo: 3 opanga akatswiri, ndi gulu laukadaulo.

4.2: Quality ndi No1, chikhalidwe chathu.

4.3: Nthawi zotsogola mwachangu: "Nthawi ndi golide" kwa inu ndi ife

4.4: 30min kuyankha mwachangu: tili ndi gulu la akatswiri, 7 * 20H

Pezani chidaliro chamakasitomala chifukwa cha mbiri yawo yotsimikizika yodalirika, magwiridwe antchito komanso moyo wautali.

 

Ngati muli ndi funsoskapena chilichonse chomwe chikufunika, chonde omasuka kundilankhula.
