Cov yam ntxwv ntawm cov qauv
- Qhov kev hloov pauv no yog cov ntaub ntawv hlau -cov qauv kaw. Raws li lub teb chaws tus qauv GB3906 thiab thoob ntiaj teb standardIEC298, tiv thaiv degreeIP2X. Cov hlau-cov qauv kaw tau zoo tiv thaiv luv luv- Circuit Court tsis ua haujlwm los ntawm cov neeg nkag thiab tib neeg lub cev los ntawm kev kov cov khoom siv hluav taws xob thiab kev ua haujlwm.
- Muaj ob lub qauv ntawm lub txee: (1) lub kaum sab xis hlau vuam (2) ntu ntu sib dhos. Nyob rau hauv lub txee, muaj chav rau breaker, busbars, cables thiab relay. Hlau daim hlau cais txhua chav.
Breaker chav nyob hauv qab ntawm lub txee nrog lub siab tso tawm channel. Yog hais tias muaj ib qho hluav taws xob arc sab hauv, roj siab tuaj yeem tso tawm los ntawm cov channel.
Chav tsev tsheb npav yog nyob rau sab saum toj ntawm lub txee. Cov kab no tau txais kev txhawb nqa los ntawm epikote insulators (Ntau dua lossis sib npaug rau 8000N). Lub tsheb npav tseem ceeb yog txuas nrog cov terminals ntawm qhov hloov hluav taws xob sab saud.
Cable chav tsev yog nyob rau hauv qab ntawm lub txee. Cables yog tsau rau ntawm qhov chaw. Chav tsev no ua haujlwm ua tus sib txuas lus thaum txoj kab txuas tseem ceeb yog tsim los ua kev sib txuas lus- taw qhia.
- Txhua daim ntawv ntawm polar mus rau polar lossis polar rau hauv av rwb thaiv tsev boards (los yog compound rwb thaiv tsev) tsis siv. Thaum huab cua rwb thaiv tsev nyob nruab nrab ntawm polar mus rau polar lossis polar rau hauv av Tsawg dua lossis sib npaug li 125 hli, cov khoom siv hluav taws xob porcelain (Ntau dua lossis sib npaug rau 8000N) yog siv. Tag nrho cov no ua kom muaj kev siv hluav taws xob ntau dua thiab ruaj khov.
-
Breakers, ob qho tib si sab sauv thiab sab hauv hluav taws xob hloov pauv, hloov hauv av thiab kev sib cuam tshuam ntawm lub qhov rooj txhua tus yuav siv lub tshuab xauv hom kom tau raws li qhov yuav tsum tau ua ntawm "tsib- tiv thaiv".
- Ob chav tu, tsis sawv ntawm phab ntsa. Kev kuaj xyuas cov khoom thib ob, kev tswj xyuas kev ua haujlwm ntawm mechanics / interlocks / kis tau tus mob / breakers yog nyob rau hauv pem hauv ntej. Thaum lub sij hawm tu lub tsheb npav bar thiab chav cable yog nyob rau tom qab. Teeb pom kev zoo yog muaj rau kev soj ntsuam hauv lub txee. Cov tsheb npav tooj liab rau hauv av hauv qab lub qhov rooj yog sib npaug rau qhov dav ntawm lub txee.
Cov khoom ua tau raws li qhov xav tau rau cov xwm txheej nruj I. siv tau nyob rau hauv lub sijhawm uas nquag khov thiab me ntsis av.
