摘要
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。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。认为角环数目最好不超过3个,并尽可能采用成型角环。
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. 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. It discussed the action of angle rings in main insulation configurations of power transformer. It's better to get no more than 3 angle rings and use forming angle rings.
