GGD AC low-voltage switchgear
Product Overview
GGD AC low-voltage switchgear yog tsim rau lub zog faib hluav taws xob nrog AC 50Hz, ntsuas kev ua haujlwm ntawm 380V, thiab ntsuas kev ua haujlwm tam sim no txog li 3150A hauv cov chaw tsim hluav taws xob, cov chaw ua haujlwm, cov chaw tsim khoom thiab cov chaw lag luam mining, rau lub hom phiaj ntawm kev hloov hluav taws xob, kev faib tawm, thiab tswj cov khoom siv hluav taws xob, teeb pom kev zoo thiab kev faib khoom.
GGD AC low-voltage switchgear yog ib hom tshiab ntawm AC low-voltage switchgear tsim raws li qhov yuav tsum tau muaj ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob, cov neeg siv hluav taws xob loj thiab cov chaw tsim khoom, raws li cov hauv paus ntsiab lus ntawm kev nyab xeeb, kev lag luam, kev tsim nyog thiab kev ntseeg tau.Cov khoom nta muaj peev xwm tawg, zoo dynamic thiab thermal stability, hloov tau hluav taws xob schemes, yooj yim ua ke, muaj zog practicality, tshiab qauv, thiab kev tiv thaiv theem, thiab yuav siv tau raws li ib tug tshiab khoom rau ua tiav poob lawm ntawm low-voltage switchgear.
GGD AC low-voltage switchgear kuj ua tau raws li cov qauv xws li IEC439 "Complete Low-voltage Switchgear thiab Controlgear" thiab GB7251 "Low-voltage Complete Switchgear."
Cov xwm txheej ntawm kev siv
Cov huab cua puag ncig yuav tsum tsis txhob siab tshaj +40 ℃ thiab tsis qis dua -5 ℃, thiab qhov nruab nrab kub nyob rau hauv 24 teev yuav tsum tsis txhob tshaj +35 ℃;
Kev teeb tsa sab hauv tsev raug pom zoo, thiab qhov siab ntawm qhov chaw siv yuav tsum tsis pub tshaj 2000m, uas yuav tsum tau teev thaum xaj;
Cov av noo nyob ib puag ncig yuav tsum tsis pub tshaj 50% ntawm qhov kub siab tshaj ntawm +40 ℃, thiab cov av noo ntau dua (piv txwv li 90% ntawm +20 ℃) tso cai rau qhov ntsuas kub qis dua los txiav txim siab qhov ua tau ntawm condensation los ntawm kev hloov pauv. nyob rau hauv qhov kub thiab txias;
Thaum ntsia, lub incline los ntawm ntsug nto yuav tsum tsis txhob ntau tshaj 5 °;
Cov khoom siv yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj kev vibration loj lossis poob siab thiab tsis zoo li yuav ua rau corrosion ntawm cov khoom siv hluav taws xob;
Cov neeg siv khoom tuaj yeem sib tham nrog cov chaw tsim khoom kom ua tau raws li cov kev cai tshwj xeeb.

Daim duab Dimensional Drawing
kev txiav txim rau kev txiav txim:
Thaum tso ib qho kev txiav txim, tus neeg siv yuav tsum muab:
- Daim duab qhia kev faib hluav taws xob tseem ceeb thiab daim duab teeb tsa, ntsuas kev ua haujlwm voltage, ntsuas kev ua haujlwm tam sim no, kev tiv thaiv cov cuab yeej teeb tsa tam sim no, thiab cov kev ntsuas tsim nyog.
- Qhia qhov tshwj xeeb ntawm cov kab nkag thiab tawm.
- Qauv, specifications, thiab kom muaj nuj nqis ntawm lub ntsiab hluav taws xob Cheebtsam nyob rau hauv lub hloov txee.
- Yog tias yuav tsum muaj cov txuas tsheb npav lossis qhov chaw npav yuav tsum tau nruab nrab ntawm cov khoom siv hloov lossis cov khoom nkag, cov kev cai tshwj xeeb xws li ncua thiab qhov siab ntawm av yuav tsum tau qhia.
- Thaum hloov cov khoom siv hauv ib puag ncig tshwj xeeb, cov lus qhia ntxaws yuav tsum tau muab thaum xaj.
- Nto xim ntawm lub txee hloov thiab lwm yam kev xav tau tshwj xeeb.
