Xaiv txoj cai transformer bushing yuav tsum xav txog qhov tseem ceeb xws li qib voltage, tam sim no, kev khiav hauj lwm ib puag ncig, thiab rwb thaiv tsev qauv. Nws yog feem ntau pom zoo kom xaiv qhov tseem ceeb ntawm cov rwb thaiv tsev yam tseem ceeb raws li seb qhov ntsuas hluav taws xob ntau tshaj 40.5kV.
Xaiv lub Main Insulation Structure los ntawm Voltage Level
Voltage theem yog qhov tseem ceeb rau kev txiav txim siab hom bushing:
Rated voltage> 40.5kV: Capacitive bushing yuav tsum tau xaiv. Nws lub ntsiab rwb thaiv tsev muaj cov tub ntxhais capacitor, ua tiav los ntawm kev sib hloov txheej ntawm cov ntawv insulating thiab aluminium ntawv ci, thiab impregnation nrog roj, uas ua rau cov hluav taws xob tsis sib xws. Haum rau siab -voltage systems ntawm 110kV thiab siab dua.
Rated voltage Tsawg dua los yog sib npaug rau 40.5kV: Pure porcelain los yog composite bushings tuaj yeem xaiv. Cov no muaj cov qauv yooj yim thiab tus nqi qis, tsim nyog rau kev faib khoom ntawm 35kV thiab hauv qab no.
