供应交流同步船用发电机的详细介绍

本稳压器采用先进技术，选用进口元器件，具有性能稳定可靠，调节精度高，尤其适用于轮船主机驱动力发电机。通过控制发电机励磁电压的高低，从而实现控制输出电压的稳定。如果本上本厂生产发电机，使用效果会更好。

　　发电机通常由定子、转子、端盖.机座及轴承等部件构成。 　　定子由机座.定子铁芯、线包绕组、以及固定这些部分的其他结构件组成。

　　转子由转子铁芯(有磁扼.磁极绕组)滑环、(又称铜环.集电环).风扇及转轴等部件组成。

　　由轴承及端盖将发电机的定子，转子连接组装起来，使转子能在定

^[1]子中旋转，做切割磁感线的运动，从而产生感应电势，通过接线端子引出，接在回路中，便产生了电流。

　　汽轮发电机　与汽轮机配套的发电机。为了得到较高的效率，汽轮机一般做成高速的，通常为3000转／分（频率为50赫）或3600转／分（频率为60赫）。核电站中汽轮机转速较低,但也在1500转/分以上。高速汽轮发电机为了减少因离心力而产生的机械应力以及降低风摩耗，转子直径一般做得比较小，长度比较大，即采用细长的转子。特别是在3000转／分以上的大容量高速机组，由于材料强度的关系，转子直径受到严格的限制，一般不能超过 1.2米。而转子本体的长度又受到临界速度的限制。当本体长度达到直径的6倍以上时,转子的第二临界速度将接近于电机的运转速度，运行中可能发生较大的振动。所以大型高速汽轮发电机转子的尺寸受到严格的限制。10万千瓦左右的空冷电机其转子尺寸已达到上述的极限尺寸,要再增大电机容量,只有靠增加电机的电磁负荷来实现。为此必须加强电机的冷却。所以 5～10万千瓦以上的汽轮发电机都采用了冷却效果较好的氢冷或水冷技术。70年代以来，汽轮发电机的大容量已达到130～150万

^[2]千瓦。从1986年以来，在高临界温度超导电材料研究方面取得了重大突破。超导技术可望在汽轮发电机中得到应用，这将在汽轮发电机发展史上产生一个新的飞跃。

usually by generator stator and rotor, cover. base and bearing etc. the stator consists of stator core, line. bag, and fixed the part of windings of other structures.

the rotor core (by rotor winding magnetic poles conjugate.) sliping, (also called copper ring. pediatrias delboni auriemo) and shaft fan etc. parts.

by bearing and cover the stator and rotor will generators connected together, make the rotor can set in

the steam turbine generator and auxiliary generator. in order to get a higher efficiency, make the turbine speed, usually commonly for 3,000 r.p.m. (is 50hz) or 3600 r.p.m. (frequency for 60hz). in the nuclear steam turbine speed, low but also in 1500 r.p.m. above. in order to reduce speed turbine generator generated by centrifugal force of mechanical stress and reduce the consumption of the rotor diameter, commonly done relatively small, length is larger, the slender rotor. especially in over 3,000 r.p.m. of large capacity, high strength, due to material rotor diameter is restricted, generally not more than 1.2 meters. the length of the body and the rotor speed limit is critical. when the body length to 6 times the diameter of the above, the rotor speed will close to the critical speed motors, operation of vibration may occur. so large size of the rotor speed turbine generator restricted. about 10 million kilowatts of air-cooling motor rotor size has reached the limits of the size, will increase, and only by motor capacity of electromagnetism load increases. therefore, must strengthen the motor cooling. so 5 ~ 10 million kilowatt above the steam turbine generator adopts the cooling effect good hydrogen cold or water-cooling system. since the 1970s, the largest turbo generator capacity has reached 130-150 million
