Eddy Current Sensor Rotation Adjustment for GIS Partial Discharge Detection

The patent employs a rotating detection matrix that can dynamically adjust its orientation and position. The detection matrix rotates around the GIS equipment, enabling automated scanning of multiple locations without manual intervention. This dynamic rotation mechanism significantly improves detection efficiency by continuously acquiring data from different angles and positions, eliminating the need for slow manual scanning while reducing the time required to locate partial discharge sources.

The patent replaces manual mechanical scanning with an automated detection system. The rotating detection matrix is driven by mechanical rotation mechanisms that automatically position sensors at various locations around the GIS equipment. This substitution of manual operation with automated mechanical systems eliminates human labor requirements and accelerates the detection process, directly addressing the low productivity and time loss issues.

The patent divides the detection system into multiple sensor assemblies arranged in a matrix configuration. Instead of relying on a single antenna with narrow beam characteristics, the system segments the detection function across multiple sensors positioned at different locations. Each sensor contributes to the overall detection coverage, and their combined data provides comprehensive spatial information. This segmentation approach maintains signal gain while eliminating the need for narrow beam scanning mechanisms.

The patent merges multiple detection functions into a single integrated rotating detection matrix. The matrix combines multiple sensor assemblies that work together to provide both signal amplification and wide-angle coverage simultaneously. By merging the functions of signal gain and broad spatial coverage into one unified system, the patent eliminates the trade-off between signal amplification and beam angle that exists in traditional antenna-based systems.
