Transformer bushings tuaj yeem faib ua ntau hom raws li qhov ntev ntawm rwb thaiv tsev khoom, cov xwm txheej, thiab rwb thaiv tsev rwb thaiv tsev nruab nrab. Hauv qab no yog ib qho kev faib tawm tshwj xeeb thiab cov lus piav qhia:
1. Kev faib tawm los ntawm cov qauv tseem ceeb
Muaj peev xwm busher
Roj-impregnated ntawv capacitor bushing (OIP): Lub ntsej muag tseem ceeb yog ua los ntawm cable daim ntawv, uas yog imprating nrog insulating roj thiab muab tso rau hauv ib lub plooj (porcelain tes tsho. Lub teb hluav taws xob yog coj los ntawm lub capacitor screen voltage, uas yog haum rau cov qib voltage siab (saum 100 kv).
Resin-impregnated ntawv capacitor bushing (rip): cov tub ntxhais yog qhov chaw tsis kho thiab impregnated nrog cov khoom rwb thaiv tsev, uas yog tsim rau cov khoom siv roj rwb (xws li gIS khoom siv gis).
Adhesive Ntawv Capacitor Bushing (RBP): Lub capacitor corener nrog cov roj nplaum, tab sis vim tias muaj kev tshem tawm ib feem loj, ntau lawm tau nres.
Fiberglass qhuav bushing: FRP yog siv los ua cov khoom siv rwb thaiv tsev sab nraud, uas haum rau cov khoom siv dawb.
Tsis yog-configititive bushing
Cov plooj dawb huv: Nws muaj cov yeebyam bushing thiab ib qho kev sib tw sab hauv, thiab feem ntau yog siv rau kev voltage theem ntawm 10 kV thiab hauv qab no.
2. Kev faib tawm los ntawm sab nraud insulating nruab nrab
Roj-Cua Bushing
Qhov qis dua yog raus hauv transformer roj, thiab lub sab qaum yog raug rau huab cua. Lub hnub los nag rwb thaiv tsev ua tau zoo yuav tsum tau txhim kho los ntawm lub kaus khaub ncaws lub kaus. Nws yog tsim nyog rau cov roj-raus cov hloov pauv.
Roj-Sf₆ Bushing
Sab qaum yog nyob rau hauv SF₆ roj ib puag ncig, thiab qis dua yog raus hauv cov roj. Lub siab rwb thaiv tsev lub zog ntawm SFO yog siv los luv luv qhov ntev ntev, uas yog qhov haum rau GIS khoom.
Roj-Roj Bushing
Nws yog siv nyob rau hauv scenarios qhov twg transformer qhov hluav taws xob tsis sib xws yog tso rau hauv cov roj (xws li cov hlua cab-tawm).
SF₆-SF₆ Bushing
Ob qho tib si sab saud thiab qis dua ua haujlwm hauv SF₆ roj, uas yog qhov tsim nyog rau tag nrho SF₆-faced transformers.
3. Kev cais tawm los ntawm sab hauv cov qauv saib xyuas
Hlua loj bushing
Tus neeg xyuas coj los qhia rau hauv bushing los ntawm kev hloov pauv ntawm cable, uas yog haum rau me- thiab cov hloov chaw muaj peev xwm.
Tus ncej bushing
Tus neeg xyuas coj ua ncaj qha ruaj khov rau cov pas nrig ua, uas haum rau cov xwm txheej siab tam sim no.
Conduit tam sim no-nqa bushings
Xws li hom ncaj qha (ncaj qha sib txuas ntawm cov roj davhlau ya nyob twg ntawm cov roj davhlau ya nyob twg thiab bushing) thiab pas nrig-los ntawm hom, haum rau cov kev xav tau siab thiab cov kev xav tau siab tam sim no.
4. Kev faib tawm los ntawm kev siv cov xwm txheej
40 kv thiab qis dua cov bushings high-tam sim no
Xws li Qws-Hom ntshiab plooj (rau nruab nrab muaj peev xwm Generator transformer) thiab capercitor bushings qes-roj hluav taws xob transformer).
40 KV thiab hauv qab cov nplaim hluav taws kub
Xws li Qws-Hom (rau Transformer Tsawg-Voltage Bushings) thiab cable-los ntawm hom (rau 10 ~ 20 KV High-voltage tawm).
66 KV thiab saum toj-ntawv-ntawv muaj peev xwm capacitor bushings
Tus rwb rwb thaiv tsev yog cov roj-impregnated cable daim ntawv thiab aluminium ntawv ci capacitor core, haum rau cov qib voltage ntau.
5. Kev faib tawm los ntawm cov khoom siv thiab cov txheej txheem
Resin-Castel Capacitor Bushings
Lub capacitor core yog pov nrog epoxy cob qhia los ua rwb thaiv tsev khov, haum rau cov roj-ib puag ncig.
Silicone Roj Hmab Composite Casing
Cov rwb thaiv tsev sab nraud yog ua los ntawm cov khoom siv roj hmab silicone
