Abstract
The utility model discloses a monitoring device of transformer states. The device comprises a remote monitoring module, a transformer on-site monitoring module and a data communication module. The data communication module comprises a signal processing unit, an A/D conversion unit, a data management unit, a data display unit and a communication unit. The transformer on-site monitoring module transmits a collected state signal to the signal processing unit. After amplified and filtered, the signal is subjected to A/D conversion by the A/D conversion unit and then is connected with the data management unit. The data management unit performs analysis and processing of the collected signal data, the data display unit performs real-time data display, and the communication unit performs transmission to the remote monitoring module. The device can effectively and automatically determine and process the transformer states, provides data support for electric power system maintenance, and facilitates operation and protection of the electric power system.
