Low-voltage circuit breakers-MCCB

1. Kodi ndi chiyaniMtengo wa MCCB ?

Ma mold case circuit breakers amatha kudzidula okha mphamvu yapano ikadutsa paulendo.Mlandu wa pulasitiki umatanthawuza kugwiritsa ntchito ma insulators a pulasitiki ngati chotchingira chakunja cha chipangizocho kuti azitha kusiyanitsa ma conductor ndi zitsulo zokhazikika.Zomangira zomangika zimakhala ndi gawo loyendera maginito lotenthetsera, pomwe mitundu yayikulu imakhala ndi masensa akuyenda mokhazikika.Gawo laulendo lagawidwa mu: ulendo wamagetsi wotentha ndi ulendo wamagetsi.Nthawi zambiri oveteredwa mafunde ndi motere: 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.

2. Mbali yaMtengo wa MCCB ?

2.1:Tsatirani miyezo ya GB14048.2008;

2.2:Oveteredwa kutchinjiriza voteji: 800V;

2.3:Kukula kwa chimango adavotera panopa: 63A;100A;225A;400A;630A;800A;

2.4:High kuswa mphamvu: mpaka 100kA;

2.5:Kupanga koyenera, kotetezeka komanso kodalirika, kukula kwa samll, kulemera kopepuka, mawonekedwe okongola;

2.6:Chalk chirichonse, unsembe mwamsanga, yosavuta kugwiritsa ntchito, applicability wamphamvu.

3.MotaniMtengo wa MCCBntchito?

Kulumikizana kwakukulu kwa otsika-voltage circuit breaker amatsekedwa pamanja kapena 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 kwapamwamba chimakokedwa kuti chipangitse njira yomasulira yaulere, ndipo kukhudzana kwakukulu kumadula dera lalikulu.

Dera likadzadzaza, chotenthetsera chotulutsa chotenthetsera chimapindika bimetal, kukankhira njira yotulutsa yaulere kuti igwire ntchito, ndipo cholumikizira chachikulu chimadula gawo lalikulu.

Derali likakhala ndi mphamvu yamagetsi, chida cha under-voltage release chimatulutsidwa, chomwe chimapangitsanso njira yaulere yaulendo, ndipo kukhudzana kwakukulu kumadula dera lalikulu.

Pamene batani la shunt tripping likanikizidwa, chida cha shunt tripper chimakoka, kupangitsa kuti njira yaulere igwire ntchito, ndipo cholumikizira chachikulu chimadula dera lalikulu.

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.
