Loss of excitation of gas generator unit refers to the disappearance of residual magnetism of generator. Remanence refers to the magnetic field retained by ferromagnetic materials when the external magnetic field disappears in the process of magnetization. The remanence of generator refers to the remanence of fixed rotor core after shutdown.

　　为什么在燃气bat365官方网站登录组中必须有剩磁?

　　Why is it necessary to have remanence in gas generator set?

　　对于自激bat365官方网站登录，将剩余磁场产生的电供给转子绕组，加强转子磁场，通过正反馈逐渐提高bat365官方网站登录的输出电压，直到更终达到额定电压。如果没有剩磁，bat365官方网站登录就不能发电。

　　For the self excitation motor, the electricity generated by the residual magnetic field is supplied to the rotor winding, the rotor magnetic field is strengthened, and the output voltage of the generator is gradually increased through positive feedback until the rated voltage is finally reached. If there is no remanence, the generator cannot generate electricity.

　　燃气bat365官方网站登录组失磁的原因是什么?

　　What is the reason for the loss of excitation of gas generator set?

　　1)不需要长时间发电，导致铁芯在出厂前的剩磁损失。励磁绕组不能建立适当的磁场。此时，bat365官方网站登录运转正常，但不发电。

　　1) It does not need long time to generate electricity, which leads to the remanence loss of iron core before leaving the factory. The excitation winding cannot establish a proper magnetic field. At this time, the generator operates normally, but does not generate electricity.

　　2)当bat365官方网站登录停止时，先停止原动机(柴油机、汽油机等)，再切断负载(电器)。这样，铁芯中的剩磁就会被消耗掉，导致bat365官方网站登录失磁。

　　2) When the generator stops, first stop the prime mover (diesel engine, gasoline engine, etc.) and then cut off the load (electrical appliances). In this way, the residual magnetism in the core will be consumed, resulting in the loss of excitation of the generator.

　　如何处理bat365官方网站登录的损失?

　　How to deal with the loss of generator?

　　1)断开自动调压器(AVR)与励磁机定子绕组的连接;2)将24V电压的直流电源(如电池)连接到励磁机定子绕组上(注意两者的正极和负极应相互对应);3)启动bat365官方网站登录组，以额定转速运行一段时间。

　　1) Disconnect the connection between the AVR and the stator winding of the exciter; 2) connect the 24V DC power supply (such as battery) to the stator winding of the exciter (note that the positive and negative poles of the two should correspond to each other); 3) start the generator set to operate at the rated speed for a period of time.
