电气设备绝缘预防性试验中的介质损失角正切的测量，则是一种使用较多而且对判断绝缘较为有效的方法。
The measurement of dielectric loss angle is one of the main methods in the preventive tests for the insulation of electrical equipment.
通过对电力变压器绕组端部绝缘结构尺寸与最大场强的计算，确定了角环的形状。
This paper determined the shape of the Angle rings through which calculated the ending dimension of winding-insulation configurations and the maximum electric field intensity.
因此绝缘测试应在变压器注油静止24小时后进行较为可靠。3、铁芯回装应注意其尖角。
Therefore, the transformer insulation test should be conducted 24 hours after the grease still more reliable. 3, the core back to the equipment should be noted that the sharp corners.
采用试探法确定了角环数目及布置方式，从而降低了端部绝缘结构尺寸。
It used exploration method to fix the amount and means of arrangement for Angle rings, thereby to reduce the ending dimension of winding-insulation configurations.
