Abstract

Oil immersed shunt reactor is one of the most important reactive power compensation equipment in Ultra high voltage (UHV) long-distance power transmission and transformation system. When the oil immersed shunt reactor has potential defects, the vibration signal during operation will be different from that under normal condition, which is shown as different defect signals such as noise and abnormal temperature. Compared with traditional vibration sensor detection, acoustic detection and infrared detection realize non-contact detection, which is safer and does not require complex vibration sensor layout. If the two are combined, the detection efficiency can be greatly improved.In this paper, the acoustic characteristics and thermal distribution characteristics of oil immersed shunt reactors under different vibration modes are studied. Based on the beam forming sound source space positioning calculation method, after the integration of voiceprint and infrared image is completed, the acoustic imaging and infrared detection technology of reactor vibration is proposed to realize the simultaneous monitoring of reactor sound temperature state information, and improve the accuracy and rationality of defect identification. In addition, the design scheme of a prototype for on-site acoustic infrared detection of reactor vibration is proposed. The related results of this paper can provide technical support for the application of UHV oil immersed shunt reactor state assessment and diagnosis, and improve the level of equipment operation and maintenance.
