Title:
MONITORING AND ALARM SYSTEM FOR TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2022/000640
Kind Code:
A1
Abstract:
A monitoring and alarm system for a transformer comprises a monitoring sensor group (1), a data acquisition station (2), and a monitoring and analysis station (3). The monitoring sensor group (1) is used to acquire safety parameter information of the transformer, and the safety parameter information is uploaded to the monitoring and analysis station (3) by means of the data acquisition station (2). The safety parameter information comprises thermal state distribution, corona discharge intensity, respective contents of hydrogen, carbon monoxide, carbon dioxide, methane, acetylene, ethylene, and ethane dissolved in transformer oil, an earth leakage current, the amplitude, the polarity, and the phase of a discharge signal, the number of discharges, respective vibration amplitudes of a transformer winding, an iron core, an oil pump, and a fan, and respective temperatures of the transformer winding and an oil tank. The monitoring and analysis station (3) performs monitoring and issues alerts with respect to the transformer according to the safety parameter information. The system uses the monitoring sensor group (1) to acquire the safety parameter information of the transformer, which enables the system to perform comprehensive monitoring of safety elements of the transformer, thereby improving the accuracy of fault detection performed on the transformer.
