Txheej txheem cej luam
GCK low-voltage rho tawm switchgear yog dav siv nyob rau hauv fais fab nroj tsuag, metallurgical dov, petrochemical, lub teeb kev lag luam thiab textile, ports, tsev, tsev so thiab lwm qhov chaw raws li AC peb-theem plaub-xaim los yog tsib-xaim system, voltage 380V, 660V, zaus 50Hz, ntsuas Nws yog siv rau kev faib hluav taws xob thiab lub cev muaj zog hauv kev tswj hwm hauv lub zog hluav taws xob nrog cov tam sim no ntawm 5000A thiab hauv qab no.
GCK yog lub tshuab hluav taws xob qis hluav taws xob siab sib dhos thiab sib dhos, thiab tsim los ua kom tau raws li cov qauv hauv qab no:
Lub teb chaws tus qauv GB7251.1-2005 "Low-voltage switchgear"
International txuj IEC60439.1-1992 "Low-voltage switchgear thiab tswj cov cuab yeej"
Lub ntsiab lus qauv
Ib puag ncig siv li qub
◆ Qhov kub ntawm huab cua tsis siab tshaj +40 ℃, tsis qis dua -5 ℃, thiab qhov nruab nrab kub hauv 24 teev tsis siab tshaj +35 ℃;
◆ Tus txheeb ze ntsuas kub tsis tshaj 50% ntawm qhov kub siab tshaj +40 ℃, thiab qhov ntsuas kub ntawm cov txheeb ze raug tso cai nyob rau hauv qis dua, xws li 90% ntawm +20 ℃;
◆ Cua huv si, tsis muaj corrosive thiab explosive gas, tsis muaj conductive thiab insulating plua plav:
◆ Nyob rau hauv cov ntaub ntawv ntawm tsis muaj kev co tseem ceeb thiab poob siab kev co, ntsug installation, lub inclination yuav tsum tsis txhob siab tshaj 5 degrees;
◆ Qhov siab tsis tshaj 2000 meters;
◆ Lub switchgear tsim nyog rau kev thauj mus los thiab khaws cia ntawm qhov kub thiab txias hauv qab no: -25 ° C txog + 55 ° C, tsis pub tshaj + 70 ° C hauv lub sijhawm luv luv (tsis ntau tshaj 24 teev);
◆ Cov neeg siv yuav tsum sib tham nrog cov chaw tsim khoom yog tias tsis tuaj yeem ua raws li cov xwm txheej saum toj no.
