winding: adj. 1.卷绕的;绕线的,绕组的。 2.迂回曲折的, ...
the electric coil around a field magnet that produces the magneto motive force to set up the flux in an electric machine
同义词:field coil,
Alternator field winding
交流发电机磁场绕
The winding through which a current is passed to produce the primary source of flux in the machine is called the field winding
电流通过其在电机中产生主磁通的绕组称为励磁绕组。
So far , there has existed several kinds of theory of ground fault protection for field winding of generator . in these methods , pingpong bridge field ground protection is a simple and effective one
目前已有多种原理的发电机励磁回路接地保护,其中乒乓式励磁回路接地保护是一种简单有效的保护原理。
In the second part , provided that the operating mode of the turbo generator keeps unchanged when the rotor winding appears fault , the magnetic motive force of the field winding will keep unvaried
通过对发电机磁动势的分析,得出发电机在故障前后运行工况不发生变化的条件下,励磁磁动势将会维持不变的结论。
Because the fault of field windings turn - to - turn shorted do not cause much effect of the operation of the machine or its fault characteristics are not very clear , most of the faults are neglected
转子匝间短路故障对机组正常运行影响不大或故障特征不明显,因此许多匝间短路故障被忽略了,但长期运行匝间短路故障会导致转子线圈一点甚至两点接地。
The two - point to earth short fault may cause short currents whic h can lead to serious accident . so it is necessary to monitor the state of field windings of turbo - generator and detect the kind of fault and predict its inclination . thus the security level of power system will be improved
由于发电机转子两点接地故障时会产生较大的短路电流,导致恶性事故的发生,因此对发电机转子绕组进行状态监测,判断短路故障的形式和趋势是十分必要,有助于提高系统安全运行水平。
