Because insulation layers in strands and turns are very thin , they are always be out of consideration when calculating electromagnetic fields 大型水轮发电机定子绕组股线绝缘和励磁绕组匝间绝缘很薄，在以往的场计算中常忽略了它的存在。
But the whole areas of stator strands insulation may exceed that of one piece of strand and it will have certain of effect on the calculation precision 但是转子匝间绝缘整个加起来的面积接近一根导体的面积，因此这样对计算结果的精度有一定的影响。
Two sides of the copper foil from an arc circular , eliminating completely the dangers as burr breaking the insulator between turns , and making it more reliable 铜箔两边缘成圆弧形，完全消除了由于边缘毛刺破坏线圈层间绝缘的危险，使得线圈匝间绝缘更可靠。
The transient simulation of stator winding inter - turn short circuit fault has been completed successfully based on the multi - loop mathematical model 基于神经网络技术，提出了以定子负序导纳平均值作为故障特征量的异步电动机定子绕组匝间短路故障检测方法。
So , insulating material , especially the temperature rise value that winding circles the heat - resisting ability of the paper insulating material between restricted transformer 所以，绝缘材料，尤其是绕组匝间的纸质绝缘材料的耐热能力限制了变压器的温升值。
Calculating results with and without the consideration of insulation is compared and the effect of insulation to the air gap magnetic field and rotor temperature field is analyzed 在场的计算中，讨论了定子股线绝缘和转子匝间绝缘对电磁场及温度场的影响。
So relay protection ca n ' t detect fault . this is likely to burn transformer if do n ' t take any measures after turn to turn short - circuit 绕组匝间短路后仍然能带满负荷继续运行，但是如果不采取相应的措施，故障将会进一步扩大，严重者至烧毁变压器，造成巨大的经济损失。
Firstly , the theory and character of the shorted rotor windings is analyzed . a new intelligent method , i . e . genetic programming ( gp ) , is introduced 由于转子的匝间短路是发电机常见的一种故障，因此本文主要采用传统的方法和智能方法结合，对发电机转子匝间短路进行诊断。
Through analyzing the air gap magnetic field , stray loss on the surface of rotor can be worked out and moreover temperature field distribution in rotor can be obtained 通过对气隙磁场的分析可以计算出转子表面损耗，进而计算出转子的温度场分布。在场的计算中，讨论了转子匝间绝缘对电磁场及温度场的影响。
But the whole areas of stator strands insulation may exceed that of one piece of strand and it will have certain of effect on the calculation precision . the same condition occurs for the turn insulation 但是定子股线绝缘和转子匝间绝缘整个加起来的面积超过和接近一根导体的面积，因此这样对计算结果的精度有一定的影响。
