【摘要】 220KV大型变压器的相间围屏爬电事故,损失很大,它与相间的电场分布,最大电场强度密切相关。本文针对大型变压器的具体结构,相间最小距离为0.126米,线圈直径近2米,相差十几倍的情况,提出了求解相间电场的二维模型,这种简单的模型能够满足工程要求的精度,减少计算量并便于寻优计算,计算结果可供工程实际参考。更多还原

【Abstract】 The puncture screen fault of 220 KV giant transformer causes enormous losses. It is closely related to the distribution of the electric field.This paper presents a simple model for the calculation of the electric field between phases of a giant transformer. This simple two-dimensionl modeal can satisfy the accuracy requirement of the calculation. lt can help reduce the computer memory and also can be applied to the optimal calculation.更多还原
