  • Aiming at the problems of the traditional electric switchgear including the severe disturbance of the temperature measurement system by electromagnetic interference, the difficulty of lying line and the inconvenience of energy supply, etc.,a temperature on-line monitoring system was built based on surface acoustic wave measurement technique. The system used planar inverted-F antenna alternative helical monopole antenna to optimize the structure of the antenna. It broke through the limitations of the short transmission distance of the original antenna of the data concentrator. The actual installation location of the sensor was adjusted to avoid signal cross interference to the greatest extent. The actual operation showed that the system worked stably with good results, effectively solving the problem of strong electromagnetic interference, meeting the accuracy requirements of on-line temperature monitoring of the switchgear.
