Detection method for abnormal vibration state of high-voltage electrical e-quipment based onfieldbus communication
Most of the conventional detection methods of abnormal vibration state of high volt-age electrical equipment are designed by the principle of laser interference technology.In the face of a large scale of high voltage electrical equipment,there are deficiencies of long detection time,large detection error and low accuracy.In order to improve this problem,fieldbus com-munication is introduced,and the method of high voltage electrical equipment based on fieldbus communication was studied.First,the vibration sensor is used to collect the vibration signal of the electrical equipment in real time.Secondly,the principle of wavelet transform and the principle of uHF method are used to establish the uHF signal model of high voltage electrical e-quipment and denoise the vibration signal.On this basis,based on the fieldbus communication,monitor the UHF signal change in the local discharge process of the high-voltage electrical e-quipment,and detect the abnormal vibration state of the electrical equipment.According to the experimental analysis results,after the application of the proposed detection method,it can ac-curately detect the potential abnormal vibration in the operation of high voltage electrical equip-ment in a fast time,and the detection accuracy of abnormal vibration state is more than 98%,and the detection effect is significant.
