Abstract: Aiming at the problem that the temperature of high-voltage switch cabinet is not easy to monitor, this paper proposed a new method of temperature monitoring based on surface acoustic wave (SAW) technology for passive wireless sensor, which could monitor the temperature inside the high-voltage switchgear in real time. This paper expounded the constituent part of the temperature sensor structure and wireless passive temperature system of SAW. The practical application case shows that the temperature monitoring system using this technology has greatly improved the on-line monitoring level of power supply equipment in iron and steel enterprises, with the advantages of easy installation, high accurate measurement, safe and reliable operation.
Key words: high voltage switchgear; temperature monitoring; surface acoustic wave; wireless sensor
