热压温度和压力对芳纶绝缘纸介电性能的影响
Influence of Hot Pressing Temperature and Pressure on Dielectric Performance of Aramid Insulating Paper
摘要
Abstract
For deeply studying the influence of hot pressing process on the dielectric performance of aramid insulat-ing paper,the aramid insulating paper with different hot pressing temperatures and pressures is prepared,its com-pactness and dielectric performance are tested,and the micro morphology analysis is performed by scanning electron microscope.The research results show that when the hot pressing temperature is within 220-260℃ and the pressure is within 8-16 MPa,with the increase of hot pressing temperature and pressure,the dielectric constant of the insulat-ing paper shows overall a small rise trend due to the influence of crystallinity and pores in the paper.The AC break-down strength,due to the influence of the pores in the paper,improves continuously with the increases of hot press-ing parameters and tends to be stable.In the hot pressing period,temperature and pressure act together on the insulat-ing paper,in which the influence of temperature on the AC breakdown strength is larger.关键词
