A method and device for online detection and monitoring of partial discharge based on 4G transmission

Abstract

This invention relates to a method and apparatus for online partial discharge detection and monitoring based on 4G transmission. The method includes: a partial discharge detection sensor signal is connected to an input protection and isolation junction box via an SMA interface, and then uniformly connected to a high-frequency signal processing module. The high-frequency signal processing module performs bandpass amplification and charge normalization on the input pulse signal before it enters a high-speed data acquisition module. The high-speed acquisition module communicates with an edge control processor, which performs cleaning and network communication management on the high-speed acquired data according to cloud configuration. Compared with existing technologies, this invention has advantages such as significantly improved accuracy of condition diagnosis, significantly reduced data transmission pressure and cloud computing load, improved response efficiency, significantly reduced equipment deployment costs, strong adaptability to industrial scenarios, enhanced anti-interference capability and detection reliability, significantly reduced operation and maintenance costs, and significant economic benefits.
