Feasibility Analysis of Power Equipment Condition Monitoring Method Based on Broadband Vibration Sensor
摘要
Abstract
Broadband vibration signal includes both low frequency vibration signal within 1 Hz-20 kHz and high fre-quency ultrasonic signal within 20-500 kHz.In recent years,the method of using vibration signal to detect the state of such power equipment as transformer,capacitor and reactor is more and more mature.Using ultrasonic signal to detect and locate partial discharge of power equipment has also been an expertly application.In this paper,the condi-tion monitoring method based on broadband vibration sensor is proposed.The vibration of the pulsed vibration source and the ultrasonic of partial discharge of the oil-paper insulated needle board electrode are measured simultaneously by the sensor.The ultrasonic time delay is corrected by simulation.The partial discharge is identified and compared with the results obtained by pulse current method.The results show that the proposed monitoring method can detect vibration and ultrasonic well and achieve the identification of partial discharge.The method proposed is feasible for the condition monitoring of power equipment.关键词
