System and method for diagnosis of vibration abnormalities in a transformer

Abstract

A system and method for diagnosis of vibration abnormalities in a transformer are provided. The system includes at least one vibration sensor, an analysis device, and a diagnostic device. The at least one vibration sensor is configured to acquire vibration data of the transformer within at least one period of time. The analysis device is connected to the at least one vibration sensor, and is configured to establish a correlation relationship between vibration conditions of the transformer and tightening strength applied to a core coil assembly of the transformer. The diagnostic device is connected to the analysis device, and is configured to determine whether the transformer in operation has a vibration abnormality according to the correlation relationship and provide an early warning notification when the transformer in operation has the vibration abnormality.
