Abstract

The invention belongs to the technical field of power equipment fault detection of acoustic imaging, and discloses an acoustic imaging positioning system for transformer substation domain fault intelligent monitoring, which comprises a sound acquisition module, and is characterized in that the sound acquisition module comprises a plurality of sound sensor arrays; the signal processing module is used for judging whether the digital signal is a fault sound signal or a background noise signal, and if the digital signal is judged to be an abnormal fault signal, removing the background noise signal in the abnormal fault signal to obtain an effective signal; the sound signal imaging module is used for calculating and analyzing the effective signals to obtain sound signal characteristics and obtaining a sound position distribution array diagram corresponding to the sound sensor array; the image acquisition module is used for acquiring visual image data of each device; and the visual sound source positioning module is used for performing overlay analysis on the sound position distribution array diagram and visual image data to determine a sound fault position. The problems that an existing state monitoring device is high in system integration and technical complexity and not visual in detection result are solved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment fault detection by acoustic imaging, and in particular relates to an acoustic imaging positioning system and method for intelligent monitoring of substation domain faults. Background technique [0002] The substation is an important hub connecting the transmission network and the distribution network. The substation domain involves a wide variety of operating power equipment, and the operating conditions are complex and changeable. The stable and reliable operation of the equipment in the substation domain directly determines the safety of the transmission and distribution ends of the power system. . [0003] As the structure and function of power equipment become more and more complex, the state detection and fault diagnosis system of power equipment is used more and more. Mechanical vibration fault is one of the common faults of power equipment, and effective diagnosis and identifica...
