(1) The remaining magnetic is often lost after stopping. The material used by the magnetic pole of the excitation machine is close to soft steel, and the remaining magnetic is small. After the stoppage is stopped, the magnetic field disappears when the magnetic field is not available without current.
(2) The magnetic pole of the diesel generator is lost.
(3) Inspirational circuit components are damaged or the line is disconnected, short -circuit or grounded.
(4) Poor contact with the inspiration of the electrical brush of the motivation machine or insufficient pressure on the frame.
(5) Etwatings of excitation winding, the opposite of the polarity.
(6) Poor exposure to the shift of the electromechanical brush of the generator, or the pressure of the brush.
(7) The generator stator winding or rotor winding road.
(8) The generator leads to loose wiring or poor switching.
(9) Fractive fuse
9 major processing methods
(1) Store a battery, and carry out massiveness before power generation.
(2) Magnetic transfers to the DC electricity (short time) with a large fixed current in the winding, and the specific current is determined by the test.
(3) Replace the damaged element and repair the fault line.
(4) Clear the dirt on the surface of the contact, adjust the pressure of the brush, and tighten the brush.
(5) Correct the wiring and press the certain polarity.
(6) Clear the exposure to the surface dirt, grind the brush, adjust the pressure of the brush, and make the brush tightly in contact with the slip ring.
(7) Check and repair the disconnection.
(8) Connect the connector or repair the switch contact site.
(9) Check the cause of the fuse, and conclude that the diesel generator itself and the line are normal, and replace the specified fuse.
