[Retracted] Neural Network Based on Health Monitoring Electrical Equipment Fault and Biomedical Diagnosis

Table 1

Knowledge base for fault diagnosis of electrical equipment.

Fault symptom	Cause of failure
The two-phase insulation resistance of the motor is too low, the insulation of the wire skin is damaged, the coil is hot, and the vibration sound of the unit is loud	Winding overheating, winding insulation breakdown, fuse burning, and improper stator offline
The insulation resistance between stator winding conductor and iron core is too low, and the motor is overheated	The end of insulation aging winding touches the end cover, the power supply voltage is three-phase asymmetric, the voltage is too high, and the stator winding is short-circuited
Active and reactive loads of the unit decrease	Transmitter misoperation and feedback sensor failure
