【摘要】：電力變壓器在發(fā)、輸、變、配電系統(tǒng)中起著至關(guān)重要的作用,它的性能、質(zhì)量直接關(guān)系到電力系統(tǒng)運(yùn)行的可靠性和運(yùn)營效益。尋找新型聚合物材料代替絕緣紙用于變壓器固體絕緣改善電場分布和絕緣結(jié)構(gòu),將非常有利于變壓器朝著大容量、緊湊型方向發(fā)展,有非常好的應(yīng)用前景。本文選擇聚碳酸酯、聚酯薄膜兩種聚合物材料作為研究對象,并與絕緣紙對比,選擇90℃、110℃和130℃三種不同的老化溫度進(jìn)行電熱老化試驗,對材料不同老化階段的聚合度,介質(zhì)損耗因數(shù)進(jìn)行了測試,并結(jié)合物理外觀性變和掃描電鏡測試結(jié)果進(jìn)行了對比分析,為判斷這兩種材料能否成為油浸式變壓器絕緣材料提供了依據(jù)。
[Abstract]:Power transformer plays an important role in power generation, transmission, transformer and distribution system. Its performance and quality are directly related to the reliability and operation benefit of power system operation. Finding a new polymer material instead of insulation paper to improve the electric field distribution and insulation structure of transformer solid insulation will be very beneficial to the development of transformer in the direction of large capacity and compact type, and has a very good application prospect. In this paper, two kinds of polymer materials, polycarbonate and polyester film, were selected as the research objects, and compared with insulating paper, three different aging temperatures, 90 鈩，
