Txheej txheem cej luam
GCS low-voltage rho tawm switchgear yog tsim rau lub tshuab hluav taws xob faib hluav taws xob hauv cov chaw tsim hluav taws xob, roj av, tshuaj lom neeg, metallurgy, textile, cov tsev siab siab thiab lwm yam lag luam.Nyob rau hauv loj fais fab nroj tsuag, petrochemical systems thiab lwm qhov chaw nrog ib tug high degree ntawm automation thiab xav tau kev sib txuas nrog cov computers, nws yuav siv tau raws li ib tug tsim hluav taws xob thiab lub hwj chim mov system nrog peb-theem AC zaus ntawm 50 (60) Hz, ib tug rated Ua haujlwm voltage ntawm 400V, 660V, thiab ntsuas tam sim no ntawm 5000A thiab hauv qab no.Cov khoom siv hluav taws xob tsawg-voltage ua tiav cov khoom siv hluav taws xob faib hluav taws xob siv hauv hluav taws xob faib hluav taws xob, lub cev muaj zog hauv nruab nrab tswj, thiab hluav taws xob them rov qab.Kev tsim cov cuab yeej ua raws li cov qauv hauv qab no: IEC439-1 "Low-voltage switchgear thiab tswj cov cuab yeej" GB7251 "Low-voltage switchgear".
Lub ntsiab lus qauv
Kev siv ib puag ncig
◆ Cov huab cua nyob ib puag ncig yuav tsum tsis txhob siab tshaj +40 ℃, tsis qis dua -5 ℃, thiab qhov nruab nrab kub hauv 24 teev yuav tsum tsis txhob siab tshaj +35 ℃.Thaum nws dhau lawm, kev ua haujlwm derating yuav tsum tau ua raws li qhov xwm txheej tiag tiag;
◆ Rau kev siv sab hauv tsev, qhov siab ntawm qhov chaw siv yuav tsum tsis pub tshaj 2000m;
◆ Cov av noo nyob ib puag ncig tsis pub tshaj 50% thaum qhov kub siab tshaj plaws yog +40 ° C, thiab cov av noo ntawm cov txheeb ze loj tau tso cai rau qhov kub qis dua, xws li 90% ntawm +20 ° C.tsim cov teebmeem condensation;
◆ Thaum lub cuab yeej raug teeb tsa, qhov inclination ntawm lub dav hlau ntsug yuav tsum tsis pub tshaj 5 °, thiab tag nrho pawg ntawm cov khoom yuav tsum tiaj tus (raws li tus qauv GBJ232-82);
◆ Cov cuab yeej yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj kev vibration loj thiab poob siab thiab tsis txaus ua rau cov khoom siv hluav taws xob raug corroded;
◆ Thaum cov neeg siv muaj cov kev cai tshwj xeeb, lawv tuaj yeem sib tham nrog cov chaw tsim khoom.
