A distributed high-frequency partial discharge real-time acquisition and analysis system

Abstract

The application discloses a kind of distributed high-frequency partial discharge real-time acquisition and analysis system, it is related to partial discharge detection field, including: sampling module, for the sampling node of each distributed monitoring point of transmission and transformation equipment, the trigger sampling of high-frequency partial discharge signal band unique space-time identifier is executed with digital quantization processing;Dismantling module is used to the high-frequency partial discharge signal after digital quantization, and the uniqueness of signal segment of multi-order intrinsic dimension disassembly and dimension is marked;The application can dynamically adjust quantization accuracy according to signal characteristics when applied to high-frequency partial discharge acquisition and analysis scene, guarantee the integrity and accuracy of signal acquisition, through the signal disassembly and unique marking of multi-order intrinsic dimension, so that the dimension signal is fine processing, simultaneously based on the networking mode of feature dimension mutual recognition, directional efficient transmission of signal segment is completed, transmission path can be dynamically updated and signal is verified, avoid transmission loss and error.
