摘要
Abstract
The safe and reliable operation of dry-type transformer depends largely on the insulation safety of the transformer winding. One of the most important factors that can damage the insulation of dry-type transformer is that winding coils' temperature exceeds the temperature tolerance of insulating material. Therefore, an on -line temperature monitoring system for 10kV dry-type transformers is developed. The system is composed of ZigBee-based wireless temperature sensors, it could get the real -time temperature data of each phase of dry -type transformer. The data would be transferred to the monitor center by IEC60870-5-104 transmission protocol. The system software is combined by LabVIEW software. Moreover, the functions of temperature alarm and fault warning are realized by assessing the transformer's operating states with comprehensive evaluation methods. It is proved that the system possesses strong reliability and flexibility in practical use.关键词
