| Abstract: | Temperature real-time monitoring for circuit breaker contact is a technical problem of electric equipment insulation monitoring. In order to solve the problem, a SAW temperature sensor based passive wireless monitor system was designed in this paper. A temperature measuring system was built to test the performance of the sensor. The low power transmission and receiving circuits were designed. The transmission and radiation resistance characteristics of the receiving antenna, the loss resistance and the inductance were analyzed with network matching to improve the reliability and stability of the wireless communication. This system has the advantage of easily control, high accuracy, high reliability, and it can achieve the function of SF6 circuit breaker contact temperature measurement. |
