Abstract: As the grid load increases year by year, the heating problem of KYN switchgear is becoming more and more prominent, and it is very necessary to monitor the temperature in the switchgear. In view of the shortcomings of the previous KYN switchgear temperature measurement technology, the passive wireless online temperature measurement technology based on surface acoustic wave is studied, and the problems faced by the passive wireless temperature measurement technology in the use of KYN switchgear are analyzed and solutions are proposed. The case verifies the practicality and effectiveness of the technology.
Key words: KYN switchgear; heating; surface acoustic wave; passive wireless temperature measurement
