Application of Acoustic Imaging Online Monitoring in 10kV High and Low Voltage Distribution Rooms
Release time：2023.05.17 　|　 Number of views：419

State Grid XXX Power Supply Company

 

The user installed an acoustic imaging online monitoring system in the high and low voltage distribution room, and found obvious positioning points in the 10kV switchgear busbar room using the acoustic imaging online monitoring device. Automatically analyze the background data as obvious partial discharge signals. The positioning point and discharge position are shown in the figure, and the maximum ultrasonic amplitude measured is 41.6dB. At present, continuous tracking is being conducted on this point, and maintenance is planned for the next planned power outage.
