摘要：
Ultra high frequency PD (Partial Discharge) signals reflect the insulation status of GIS (Gas Insulated Switchgear) devices effectively, which are steep pulses with rising edge and pulse width in nanoseconds. A data fusion management method based on LabVIEW is proposed for online monitoring and signal processing, which integrates file management and database management together to construct a data-file fusion management system for steep pulse signal storage. Key techniques are introduced, such as the requirements and ways of data management, the database operations, the PD wave data storage, the database query and so on. Practices show that the data-file fusion management system can effectively manage the massive monitored PD data.
