Transportation Monitoring of Geo-Location, Speed, Vibration, and Shock Acceleration for 110-kV Vehicular Mobile Transformers

As a kind of transformer installed on vehicles, the vehicular mobile transformer needs to realize frequent transportation quickly and safely. However, there are few studies on the on-line monitoring of vehicular mobile transformers. In this article, a transportation condition monitoring system for vehicular mobile transformers is introduced and developed. The transportation process of a 110-kV/40-MVA vehicular mobile transformer is monitored from Jiangsu Province to Guangdong Province, which is recognized as the first time that the transformer is monitored for more than 12 h and more than 1000-km transportation. The geo-location, driving speed, vibration, and shock acceleration in six different road sections are obtained in real-time. The results show that the vibration and shock acceleration has a strong positive correlation with the driving speed. The amplitude of the $y$ -axis acceleration is generally the lowest among three-axis accelerations, and the three-axis vibration and shock acceleration has the same trend of increase and decrease. During the whole transportation process, the driving speed of the 110-kV/40-MVA vehicular mobile transformer varies from 0 to 76 km/h, and the vibration and shock acceleration amplitudes obtained by the monitoring system do not exceed 1 g, which has great significance to the safe operation of power grid and can provide the strong evidence of online monitoring data to set transportation guidelines for vehicular mobile transformers.
