摘要
击穿电压表征变压器油的绝缘性能,是变压器油重要的电气性能。介绍了试验方法、电极形状、温度和操作过程对击变压器穿电压测定值的影响。球形电极的击穿电压值较高,球盖形电极居中,平板电极较低。
The breakdown Voltage characterized the insulation performance of transformer oil ,and was the important electrical property of transformer oil. The influences of testing methods, electrode shape, temperature and operating process on determination value of transformer oil breakdown Voltage were discussed.The breakdown Voltage of spherical electrode was high ,the ball cap electrode was moderate ,and the plate electrode was low.
