This paper preliminarily analyse the relation between leakage current and voltage in the electrical imsulation test,introduce a rational voltage rising curve to lessen the damage to the insulating materials in the test.
初步分析了电气绝缘试验时施加电压与漏电流的关系,提出了在介电强度试验时一种较为合理的电压上升曲线,目的是减少介电强度试验对绝缘材料的破坏。
The results show the slope of the initial traction curve increases with the decrease of the amount of oil at low pressure and approaches the value of the dry condition at high pressure.
在低压情况下 ,牵引曲线上升斜率随着牵引油数量的减少而增大 ,并且在高压情况下其值接近于干摩擦状态下的值。
