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.

　　為什麽在燃氣好色先生在线观看中必須有剩磁?

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

　　對於自激發電機，將剩餘磁場產生的電供給轉子繞組，加強轉子磁場，通過正反饋逐漸提高發電機的輸出電壓，直到更終達到額定電壓。如果沒有剩磁，發電機就不能發電。

　　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.

　　燃氣好色先生在线观看失磁的原因是什麽?

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

　　1)不需要長時間發電，導致鐵芯在出廠前的剩磁損失。勵磁繞組不能建立適當的磁場。此時，發電機運轉正常，但不發電。

　　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)當發電機停止時，先停止原動機(柴油機、汽油機等)，再切斷負載(電器)。這樣，鐵芯中的剩磁就會被消耗掉，導致發電機失磁。

　　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.

　　如何處理發電機的損失?

　　How to deal with the loss of generator?

　　1)斷開自動調壓器(AVR)與勵磁機定子繞組的連接;2)將24V電壓的直流電源(如電池)連接到勵磁機定子繞組上(注意兩者的正極和負極應相互對應);3)啟動好色先生在线观看，以額定轉速運行一段時間。

　　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.
