开关柜绝缘件嵌入式RFID柔性温度标签天线设计研究OA

The passive wireless RFID switch cabinet temperature measurement system,compared to other tradition⁃al temperature monitoring technologies,has such advantages as easy layout,stable energy supply and self⁃organizing network communication,and has a high application prospect.Firstly,the working mechanism of RFID temperature measurement system is introduced in this paper,and the feasibility of using this system in the environment of switch cabinet is discussed.Then,a kind of RFID temperature⁃sensitive tag antenna based on flexible FPC substrate is de⁃signed,and the related performance indexes of the designed antenna are simulated and studied;Finally,the influ⁃ence of the environment and layout mode of the switch cabinet on the performance of temperature⁃sensitive tag anten⁃na is discussed in detail,and a kind of RFID flexible temperature tag layout scheme with embedded insulation(insu⁃lation bushing)is proposed in accordance with the heat source environment in the switch cabinet.The research shows that the measurement method can collect more accurate information of guide bar temperature and is easy to maintain,which has certain guiding significance for improving the intelligent level of switch cabinet and promoting the development of temperature measurement technology of power equipment.
