Fault Diagnosis System for Diagnosis and Control of Temperature, Partial Discharge and Noise of Transformers Using Sensors

摘要

The present invention relates to a fault diagnosis system for diagnosing and controlling temperature, partial discharge and noise of a transformer using a sensor, and more particularly, to a transformer; a non-powered surface wave sensor installed on the surface of the transformer winding to detect surface temperature and partial discharge in real time; A monitoring device comprising; a noise sensor that detects noise generated from a transformer; a diagnostic device for receiving a monitoring signal from the monitoring device and diagnosing whether the transformer is faulty; a PC that shares the diagnosis result by the diagnostic device and controls the operation of the transformer; and a fault diagnosis system for diagnosing and controlling the temperature, partial discharge, and noise of a transformer using a sensor including a terminal for sharing the diagnosis result and controlling the driving of the transformer. According to the fault diagnosis system for diagnosing and controlling the temperature, partial discharge and noise of the transformer using the sensor of the present invention, the temperature rise of the transformer, the occurrence of partial discharge, harmonic inflow and overload, interlayer short circuit, poor contact, relaxation of the fixed part By measuring the abnormal noise generated due to factors such as etc. and accurately diagnosing the state of the transformer, it is possible to minimize transformer damage and prevent system accidents. It measures the transformer temperature and partial discharge with one sensor, and measures the noise in a complex manner. It is possible to increase the reliability of the fault diagnosis of the transformer and reduce human error by linking it to the Durability can be improved.
