Analysis of Electromagnetic Interference for Anti-Medal UHF RFID Temperature Tag in High Power Electronic Equipment

Being inches from the rapid development of new energy technology, capacity high-power power electronic equipment is increasing rapidly, and requirements for its safe reliable operation are also rising. As a result, demand online temperature monitoring such becoming increasingly urgent. RFID measurement technology can be used real-time powered equipment. However, generates strong electromagnetic interference, which seriously affect normal systems. For applications involving internal equipment, this paper employs an anti-metal tag antenna with short-circuit cutoff structure. This structure was tested in excitation switchgear cabinet. During low-power cabinet, functioned normally. By combining model interference simulation main circuit establishes tag. It analyzes how tag’s performance parameters change when subjected to interference. Through simulation, failure mechanism during cabinet clarified. The analysis found that there both conductive radiated having more significant effect. Conductive impact tags significantly degrading their performance. In contrast, effect on relatively small. Therefore, simulates characteristics.
