Qib rwb thaiv tsev yog hais txog qib cua sov ntawm cov khoom siv insulating siv, uas tau muab faib ua qib A, E, B, F thiab H. Qhov tshwj xeeb tso cai ntsuas kub ntawm txhua theem rwb thaiv tsev yog raws li nram no: Tso cai kub ( degree ) A: 105 E: 120 B: 130 F: 155 H: 180 winding kub nce txwv (degree) A: 60 E: 75 B: 80 F: 100 H: 125 transformer epoxy castables muaj F, H thiab lwm qib. Feem ntau, qhov kev tiv thaiv ntawm epoxy resin tsis yog ib qho teeb meem, thiab muaj qee qhov sib txawv ntawm qhov tawg, tab sis qhov sib txawv tsis loj. Hauv cov khoom siv epoxy potting ntawm qhuav transformer, qib F thiab H feem ntau qhia txog qib cua sov. Tam sim no, ntau lub tuam txhab tsim F-class transformers, tab sis nrog upsizing ntawm transformers, lub tshav kub kuj yuav tsum tau nce siab dua, yog li qhov kev thov rau H-class.transformersyog ntau.
Transformers tau dav siv nyob rau hauv lub teeb pom kev zoo hauv zos, cov tsev siab siab, tshav dav hlau, terminals, CNC machinery thiab cov khoom siv thiab lwm qhov chaw, yooj yim hais tias transformer yog hais txog cov tub ntxhais hlau thiab winding tsis impregnated nyob rau hauv rwb thaiv tsev roj transformer. Cov txheej txheem cua txias tau muab faib ua cua txias (AN) thiab cua txias (AF). Thaum huab cua txias lawm, lub transformer tuaj yeem khiav tsis tu ncua rau lub sijhawm ntev nyob rau hauv lub peev xwm ntsuas. Thaum yuam cua txias, lub peev xwm ntawm lub tshuab hluav taws xob tuaj yeem nce 50%. Haum rau kev ua haujlwm tsis sib xws, lossis kev ua haujlwm kub ceev; Vim qhov loj ntawm qhov poob thiab impedance voltage thaum lub sij hawm overload, nws yog nyob rau hauv ib tug tsis-economic lag luam lub xeev, yog li nws yuav tsum tsis txhob muab cia nyob rau hauv tas li overload ua hauj lwm rau lub sij hawm ntev.
