Seven polyimides were synthesized and their films were uniaxially stretched to observe the variation in their in-plane birefringence. The creep method of DMA was used instead in stretching the PI films. The preload force and isothermal temperature were the two controlled factors that were chosen on the basis of the lowest stretchable force and lowest temperature for each PI structure. The elongation ratio of a PI film was then decided by the stretching time.

在此是以DMA 的另一种试片拉伸方式-Creep模式,来取代之前的Stress Relaxation模式对PI薄膜试片进行拉伸实验,Creep模式是以最低的拉伸力量及最低的拉伸温度的前提下,选择Pre-load Force与Isothermal Temperature这二项为拉伸控制因素,在此状态下的PI薄膜拉伸比是取决於其拉伸的时间,此种拉伸模式将可得到较高的拉伸比,而高的拉伸比是获取较高薄膜双折射率的必要条件。

The article adopts "humidity ratio" integrated emendation method and other two traditional emendation methods in emendation calculating on several group test results. The tests are : simulating test in artificial climate room on 110kV substation equipment of Yangbajing, Lasa and Yanghu by Xi"an High Voltage Lab; power frequency voltage discharge test of ZS-110 by Yunnan provincial electrical research academy. It compares and analyses the equipment test voltage emendated to standard atmosphere conditions with the equipment nominal withstanding voltage. And then it concluded that: the emendation value educed by "humidity ratio" integrated emendation method is basically equal or close to the equipment nominal withstanding voltage; but the values by two traditional emendation methods are mostly higher.It also proves that,"humidity ratio integrated emendation method is more perfect than any other methods, and it can reflect the influence degree of atmospheric parameters on electrical equipment outer insulation discharge voltage actually. The method should be spread in designing high elevation power projects.
