Online Monitoring System of Dissolved Gas in TransformerOil Device Based on VxWorks

Abstract

Abstract:

Abstract: In order to meet the requirements of intelligent substation development and further improve the stability, accuracy, remote monitoring and management of online monitoring system of dissolved gas in transformer oil device, we use the technologies of selfmade carrier gas, vacuum degassing method, constant temperature control technology and combining with the research on VxWorks operating system, embedded database SQLite and IEC61850 communication protocol, put forward a design scheme of online monitoring system of dissolved gas in transformer oil device based on VxWorks operating system. Through the field application, the results show that: this device has some advantages, such as good stability, high accuracy of operation, more practicability, high level of functional integration, supporting remote monitoring and easy management.
