Title:
ULTRAHIGH-FREQUENCY SENSOR AND ONLINE PARTIAL DISCHARGE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/152983
Kind Code:
A1
Abstract:
An ultrahigh-frequency sensor (201) and an online partial discharge monitoring system. The ultrahigh-frequency sensor (201) comprises: a signal processing circuit (1) configured to process acquired partial discharge signals; a feature extraction circuit (2) configured to extract, from the partial discharge signals, partial discharge feature parameters of an apparatus to be monitored to serve as partial discharge information; a transceiver circuit (3) comprising an antenna subsystem (31), a radio frequency front end subsystem (32), and a baseband subsystem (33) and configured to perform data exchange with the outside; and a processor (4) separately connected with the signal processing circuit (1), the feature extraction circuit (2), and the transceiver circuit (3) and configured to process the partial discharge information and control the signal processing circuit (1), the feature extraction circuit (2), and the transceiver circuit (3) to be in an asynchronous working state. According to the solution, partial discharge signals are acquired wirelessly, feature parameters are extracted to serve as partial discharge information, the amount of data needing to be transmitted is reduced, and interference of wireless communication signals on the acquired signals is avoided by means of asynchronous processing of signal acquisition and wireless communication.
