Abstract:

Abstract:In order to avoid the fire accident in switch contacts of highvoltage electrical equipments during longterm operation, a temperature measurement technology based on surface acoustic wave was proposed. The differences between the temperature measurement technology and the traditional temperature measurement technology were analyzed. The temperature measurement theory using surface acoustic wave was introduced, and a complete passive wireless temperature measurement system was developed. The system is used in the converter cabinet of a wind farm to measure inside cabnet temperature and operates well, and the temperature of the measurement points inside the cabinet can be measured real time and accurately.

Key words: Keywords:surface acoustic wave (SAW), passive wireless temperature measurement system, frequency converter for wind turbine, antielectromagnetic interference
