I. Cov kev nyab xeeb tseem ceeb ntawm qhov tshwj xeeb rau cov specifications rau tsawg- voltage tub
Kev Nyab Xeeb Kev Nyab Xeeb Cov Lus Qhia rau Tsawg - voltage txee hloov chaw "thiab" GB 5004-2011 tsawg hluav taws xob faib khoom tshwj xeeb. " Cov kev yuav tsum muaj cov lej muaj raws li hauv qab no:
1. Pem hauv ntej kev ua haujlwm deb: tsawg kawg 800mm (tsau cov txee) lossis 1000mm (ua kom muaj kev sib tw ua haujlwm rau kev saib xyuas lossis sawv ntsug ntawm GB 50054, Ntu 4.2.5).
2. Lub tsheb sib nrug deb: tsawg kawg 600mm, lossis tsawg kawg 800mm yog tias lub qhov rooj nkag tom qab.
3. Tom qab Aisle Dav: Rau ob npaug- kab pib} kev npaj ntawm cov tub rog yuav tsum yog yam tsawg 1000mm; Rau ib qho - kev npaj tiv thaiv ib phab ntsa, tsawg kawg 200 hli ntawm kev tshem tawm yuav tsum tau sab laug ntawm ob sab.
Cov Lus Cim Ntxiv:
-} Lub 800mm Hauv ntej Clearance yog raws li cov neeg laus nruab nrab ntev (kwv yees li 700mm), nrog rau cov nyiaj tau los tuav.
{{0- TXIAB - Hom Xwm uas yuav tsum muaj kev tshem tawm ntxiv.
Ii. Cov Kev Tshwj Xeeb Rau Cov Kev Nyab Xeeb Rau Kev Nyab Xeeb Kev Nyab Xeeb Sab saud qis- voltage tub
Cov kev nyab xeeb tshaj plaws saum toj qis qis - voltage txee yog feem ntau saib rau cua sov dissipation thiab siab} voltage rho tawm:
1. Sab saum toj txiav txim siab:
{{0 {0} Tus qauv qis - voltage tub me: ntau dua lossis sib npaug nrog 300mm (tshav kub dissipation yuav tsum);
{{0- Thaum lub siab-} voltage busbar yog nyob saum lub txee: ntau dua lossis sib npaug los ntawm Ntu 4.3.3 ntawm GB 50054).
