4. Thaum cov cuab yeej raug teeb tsa, qhov inclination los ntawm lub dav hlau ntsug yuav tsum tsis pub tshaj 5°.
5. Cov khoom siv yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj kev vibration loj thiab cuam tshuam, thiab qhov chaw uas cov khoom siv hluav taws xob tsis corroded.
6. Thaum tus neeg siv muaj cov kev cai tshwj xeeb, nws tuaj yeem daws tau los ntawm kev sib tham nrog cov chaw tsim khoom.
Qauv thiab Nws Lub ntsiab lus
Lub ntsiab Technical Parameters
1. Cov kev ntsuas hluav taws xob yooj yim tau qhia hauv Table 1

2. Cov txheej txheem kev pabcuam hluav taws xob
Kev tsim cov khoom siv hluav taws xob tau muab faib ua ob ntu: kev npaj hluav taws xob thiab cov phiaj xwm cog hluav taws xob.
3. Lub tsheb loj
Thaum qhov ntsuas tam sim no yog 1500A thiab qis dua, ib lub tsheb npav bronze siv.Thaum qhov ntsuas tam sim no ntau dua 1500A, ob lub npav tooj liab siv.Qhov sib tshooj ntawm cov busbars tau kho nrog tin hauv ob sab phlu.
4. Kev xaiv cov khoom siv hluav taws xob
ib.GGD txee feem ntau txais cov khoom siv hluav taws xob ntau dua uas tuaj yeem ua tau ntau hauv Suav teb.Xws li DW17, DZ20, DW15, thiab lwm yam.
b.Lub 1ID13BX thiab HS13BX rotary-operated riam keyboards yog cov khoom tshwj xeeb tsim los ntawm NLS kom tau raws li qhov xav tau ntawm cov qauv tshwj xeeb ntawm GGD txee.Nws hloov pauv kev ua haujlwm ntawm lub tshuab ua haujlwm thiab khaws qhov zoo ntawm cov khoom qub.Nws yog ib hom tshiab ntawm cov khoom siv hluav taws xob.
c.Piv txwv li, thaum lub tuam tsev tsim qauv xaiv cov khoom siv hluav taws xob tshiab nrog kev ua tau zoo dua thiab cov thev naus laus zis ntau dua raws li cov neeg siv khoom xav tau, vim tias GGD txee muaj qhov yooj yim installation, feem ntau nws yuav tsis ua rau muaj kev tsim khoom thiab teeb meem vim yog cov khoom siv hluav taws xob tshiab.
d.Txhawm rau txhawm rau txhim kho kev ruaj ntseg ntawm lub voj voog, lub tsheb thauj mus los ntawm GGD txee txais yuav ZMJ hom kev sib xyaw tsheb npav thiab kev txhawb nqa insulating.Lub busbar clamp yog ua los ntawm lub zog siab, siab nplaim-retardant PPO cov khoom sib xyaw, nrog lub zog rwb thaiv tsev siab, kev ua haujlwm zoo ntawm tus kheej, thiab cov qauv tshwj xeeb.Nws tuaj yeem yooj yim ua ke rau hauv ib lub busbar lossis ob lub busbar clamp los ntawm kev kho lub tsev thaiv.Cov kev txhawb nqa insulating yog lub tes tsho-hom molded qauv nrog tus nqi qis thiab lub zog siab, uas daws cov teeb meem ntawm qhov tsis txaus creepage nrug ntawm cov khoom qub.
