XGN2 Case-style Fixed Hlau-Nplhaib npogMib ainUnit
Generalization
XGN2-10 Case-style Tsau Hlau-Txuas Nplhaib lub ntsiab chav tsev (Switchgear) feem ntau yog siv los txais thiab faib cov khoom siv hluav taws xob ntawm 3.6, 7.2 thiab 12KV, 3Phase AC, 50Hz sab hauv tsev. Nws yog siv tshwj xeeb rau cov xwm txheej uas yuav tsum tau ua haujlwm ntau zaus. Lub switchgear mus raws li lub xeev Standard GB3906 thiab International Standard IEC298 thiab muaj nruj "tsib tiv thaiv" xauv muaj nuj nqi.
Lub ntsiab hloov siv ZN28A-12 segmental hom nqus tsev vacuum nrog Cd10 electromagnetic ua hauj lwm mechanics, CT8 / CT19A (B) caij nplooj ntoos hlav ua haujlwm mechanics, ZN28-12 series ib lub tshuab nqus tsev vacuum (nrog CD17 Electromagnetic Operational mechanics, CT17 / CT19S12) vacuum mechanics (CTV-12) Circuit Court breaker. Kev rho tawm hloov siv GN30-10 rotating style thiab GN22-10 siab tam sim no rho tawm hloov.

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 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 saud 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.
Tsis muaj polar-rau-polar lossis polar- mus rau- cov ntaub ntawv rwb thaiv tsev hauv av (los yog cov khoom siv rwb thaiv tsev sib xyaw) siv. Thaum lub rwb thaiv tsev nyob deb ntawm tus ncej lossis los ntawm tus ncej mus rau hauv av tsawg dua lossis sib npaug li 125 hli, cov khoom siv hluav taws xob porcelain nrog lub zog siv hluav taws xob ntau dua lossis sib npaug ntawm 8000 N. Cov kev ntsuas no ua kom muaj zog rwb thaiv tsev ntau dua thiab ntev - lub sijhawm ruaj khov.
Cov hluav taws xob hluav taws xob, ob lub qhov hluav taws xob sab sauv thiab sab qis, cov hloov pauv hauv av, thiab cov txheej txheem sib cuam tshuam ntawm lub qhov rooj txhua tus txais yuav lub tshuab kaw lus yuam kom ua tau raws li "tsib- kev tiv thaiv" kev nyab xeeb.
Chav tsev txhawb nqa ob- kev saib xyuas ib sab thiab tsis tas yuav tsum tau teeb tsa phab ntsa. Kev nkag mus rau pem hauv ntej tso cai rau kev tshuaj xyuas cov khoom nruab nrab thiab kev saib xyuas cov txheej txheem kev khiav haujlwm, kev sib cuam tshuam, qhov chaw sib kis, thiab cov khoom tawg, thaum lub tsheb nkag tau muab rau kev saib xyuas busbar thiab cable compartment. Sab hauv teeb pom kev zoo saib xyuas sab hauv lub txee, thiab tooj liab grounding busbars hauv qab lub qhov rooj tau teem caij sib npaug rau lub txee dav.
Cov khoom ua tau raws li qhov yuav tsum tau muaj ntawm Kev Kho Mob I, ua rau nws tsim nyog rau ib puag ncig uas tsis tshua muaj khov thiab muaj paug tsawg.
