Transformer bushings yog cov khoom siv insulating uas txuas cov siab -voltage thiab low-voltage coj hauv lub transformer mus rau sab nraud ntawm lub tank. Lawv tsis tsuas yog muab rwb thaiv tsev ntawm cov coj thiab hauv av tab sis kuj txhim kho cov coj thiab txhawb nqa lub peev xwm tam sim no, ua rau lawv yog ib qho tseem ceeb tshaj plaws ntawm cov rwb thaiv tsev sab nraud thiab tam sim no - nqa cov khoom ntawm lub transformer.
Raws li lawv cov qauv thiab cov txheej txheem rwb thaiv tsev, transformer bushings feem ntau muab faib ua pawg hauv qab no:
Pure Porcelain Bushings
Feem ntau siv nyob rau hauv transformers ntawm 10kV thiab hauv qab no. Lawv muaj cov qauv yooj yim, uas muaj cov plooj (porcelain bushing) thiab cov pas nrig tooj liab hla dhau los ntawm nws, nrog cua rwb thaiv tsev sab hauv.
Roj-Pov Bushings
Feem ntau siv hauv 35kV transformers. Cov plooj (porcelain bushing) yog ntim nrog cov roj insulating, thiab cov pas nrig conductive yog qhwv nrog ntawv insulating los txhim kho kev ua haujlwm rwb thaiv tsev. Lawv feem ntau txuas nrog lub tank transformer.
Capacitive Bushings
Siv nyob rau hauv transformers ntawm 110kV thiab saum toj no. Siv lub hauv paus ntsiab lus ntawm kev faib hluav taws xob hluav taws xob, ntau txheej txheej ntawm cov ntawv hlau hlau thiab cov khoom siv insulating yog interleaved los ua ib lub capacitor core, kom ntseeg tau tias cov hluav taws xob tsis sib xws raws cov bushing thiab txhim kho lub zog rwb thaiv tsev. Nyob ntawm cov khoom siv rwb thaiv tsev, lawv tuaj yeem muab faib ntxiv rau hauv cov roj-paper capacitors thiab nplaum-paper capacitors, nrog rau tom kawg muaj zog dua txhua yam.
Fiberglass Dry Bushings
Siv nyob rau hauv qhuav- hom transformers, lawv yog ua los ntawm cov ntaub ntawv sib xyaw xws li fiberglass thiab muaj cov rwb thaiv tsev zoo thiab muaj peev xwm txhawb kev siv tshuab, haum rau cov roj- ib puag ncig dawb.
