With the aim of analyzing the laminated pressboard's applicability in an oiled transmission transformer,mechanical properties were tested by using a laminated pressboard made up of the single pressboard with the thickness of 2mm,3mm and 5mm respectively.
为了研究层压纸板在油浸式输电变压器中的适用性,将单张厚度分别为2、3、5mm的纸板加工成层压纸板标准试件,进行力学性能测试。
Pressure of the rider roll greatly influence the rewound roll’s profile, the traditional pressure control curve is based on the steady model of the winder,but this kind of pressure curve can only produce a fairish profile ,that the profile at the end of the accelerated process is usually ragged.
复卷机的压纸辊压力对成品纸卷的端面有较大影响,传统的压力控制曲线是由稳态模型而来,按照这种方法调节压纸辊的压力虽然能得到满意的纸卷端面,但是在复卷机加速到指定工作车速的时候,成品纸卷的端面常常出现小范围的参差不齐,破坏了纸卷整体的平整。
