目前大型水轮发电机定子绕组普遍采用多分支双层波绕或叠绕的结构，文章针对这2种绕组结构，详细分析了发电机内部可能发生的所有故障形式特点，设计了可形成各自故障集的通用算法，并介绍了该算法在三峡左岸Alstom电机和柘溪电站扩建工程发电机定子故障形式分析中的应用。

It results in much less leakage flux than would be the two windings were separated by a distance on the core.

It结果清盘比在两个绕组是由一对相距遥远的核心问题。

The intensity of the magnets in permanent-magnet motors can increase as the motor size and output power increase. This causes difficulty in manufacture of large scale PM motors and consequently increases the cost. Post-assembly magnetization can be treated as a solution to the above problem, which fabricates the motors before the magnet is magnetized by applying large current impulse on the motor stator windings.

中文摘要由於永磁马达转子磁铁强度，会随著马达尺寸与输出功率增加而增加，导致大型永磁马达在制作上，因磁铁的强磁性造成组装上的困难，且易有铁粉等杂物附著，使得制作成本增加，故有必要使用新的充磁技术或特殊制程解决。

本绕线机控制系统，既可以预先设定800多种规格或型号的绕组，又可以根据用户需要随时设置新型绕组。

All the vales in their manifold windings shaded by the most delightful forests.

所有的幽谷，都笼罩在繁茂的垂枝下。

The journey of growth can be compared as a road which is long, complicated, full of windings and wrong turnings.

一次道路漫长、路线复杂、充满了迂回绕路和错误的转弯的旅途可以被看做是代表了成长的历程。

Based on the wall temperature of hollow wire, the further calculation program has been given. It account for the complexity of the stators structure and can be used in the calculation of the temperature distributions in arbitrary cross section of windings.

在空心导线壁温分布计算方法确立的基础上，充分考虑到定子线棒结构的复杂性，采用有限差分的方法编制了通用性较强的线棒截面温度分布计算程序。

We believe that the Open-phase transient phase in the broken ends of windings have several times higher than the rated voltage of the anti-.

我们认为断相瞬间在断相绕组两端产生高于额定电压数倍的反。

Because of the off-phase motor running to recognize the harm caused by different fault in the implementation phase of the motor protection have had two different views: that the broken phase to the electrical damage caused by overheating point of view to the implementation of the motor overheating protection or inverse-time characteristics of overcurrent protection, thermal relays the resulting program, thermal resistance package with over-current fault protection program delay, and other programs; that the break caused by phase to the motor windings high-voltage breakdown back-EMF's view of Open-phase protection program to take instantaneous action, and some electronic-type protectors available.

由于对断相运行给电机造成的危害认识不同，因此在对电机实行断相保护时产生了两种不同的意见：认为断相给电机造成过热损坏的观点要对电机实行过热保护或过流反时限特性保护，由此产生了热继电器方案、热敏电阻方案、断相过流延时保护方案以及其他一些方案；认为断相给电机绕组造成高压反电势击穿的观点，对断相采取瞬时动作保护方案，于是一些电子式保护器问世。
