Cov qauv qauv yog tsim los ntawm cov qauv thiab cov tub rau khoom sib xyaw ua ke nrog cov khoom siv hluav taws xob txhim khu kev qha, ua kom muaj kev ntseeg siab thiab muaj kev nyab xeeb dua rau cov neeg siv.
Qhov no hloov pauv tau haum rau peb {-}} hlau siv voltage ntawm 400v thiab ib tug rated tam sim no ntawm 5000a lossis tsawg dua. Nws tuaj yeem siv rau hauv cov nroj tsuag hluav taws xob, hloov, kev lag luam thiab chaw nres tsheb, fais fab, fais fab, thiab siv fais fab, thiab siv hluav taws xob. Nws tseem tuaj yeem ua cov kev them nyiaj kho mob rau lub ntsiab busbar loj los ntawm capacar them khoom txee.
Cov khoom no ua raws li cov cai ntawm cov qauv xws li GB7251 {{- - {{
Cov kev pabcuam ib txwm muaj
● Cov ntsuas kub yog qhov kub thiab txias: Qaum Qeeb +40 degree, qis dua-15℃(qis rau -45℃nrog cov txheej txheem tshwj xeeb);
Exitude tsis tau tshaj 2500m (txog 4000m nrog cov txheej txheem tshwj xeeb);
Tus txheeb ze cov cua ntawm cov huab cua ib puag ncig yuav tsis pub tshaj 50% ntawm qhov kub tshaj plaws ntawm +40 degree. Ntawm qis dua kub, cov txheeb ze cov av noo yog siab dua, xws li 90% ntawm {4 4}} degree. Txawm li cas los xij, nws yog suav tias yog qhov kev hws hws yuav tshwm sim vim qhov ntsuas kub hloov.
Nws yuav tsum tau nruab rau hauv qhov chaw muaj kev kub loj los ntawm kev co loj thiab poob siab, thiab qhov twg cov khoom siv hluav taws xob yuav tsis xeb.
Thaum cov kev siv tau saum toj no tau tshaj li, tus neeg siv yuav sib tham nrog cov chaw tsim khoom los txiav txim.

Tus qauv thiab qhov ntev
MnS series Switchgear yog ntsia kab ntsug thiab tsis tawm tsam ib lub phab ntsa. Tom qab ntawm lub txee yog lub cable trench rau cov cable cable. Txhawm rau pab txhawb kev kho, qhov kev ncua deb ntawm lub nraub qaum rau phab ntsa feem ntau yog 800 rau 1200 hli. Lub installation nrug nyob rau pem hauv ntej yog qhia nyob rau hauv daim duab hauv qab no.
