Latest Patents

Yiming Wu holds a patent for a "Fault diagnosis and preliminary location system and method for transformer core looseness." This invention presents a fault diagnosis and location system that utilizes vibration sensors, data collection, and computer analysis. The method employs three vibration sensors positioned on the top of the transformer tank to capture vibration signals. Through signal processing, the system analyzes these signals to identify fault characteristics associated with transformer core looseness. The key frequency components identified are 50 Hz, 150 Hz, and 300 Hz, with 300 Hz being the primary feature. When the signals reach a specific value at a given position, it indicates potential core looseness. By comparing the differences among signals from the three positions, the fault location can be accurately determined. This invention effectively manifests fault characteristics and efficiently detects core looseness.
