基于声表面波的高压断路器灭弧室压力测量装置
摘要：
本发明涉及一种基于声表面波的高压断路器灭弧室压力测量装置，包括全密闭结构的高压断路器灭弧室，在灭弧室内放置声表面波传感器标签，在灭弧室外放置声表面波接收器。所述声表面波传感器标签固定于灭弧室内侧墙壁上，其位置与灭弧室外部放置的声表面波接收器位置相对应，两者的距离在40CM范围内。所述声表面波接收器发射天线的方向指向声表面波传感器标签，本发明可实现对灭弧室内压力变化情况施行监控，解决了长期以来没有有效手段对电力系统高压断路器灭弧室的实时监测，在技术手段上实现了重大突破。
摘要（英）：

The invention relates to a device for measuring pressure of a high-voltage circuit breaker arc extinguish chamber based on acoustic surface waves. The device comprises the high-voltage circuit breaker arc extinguish chamber of a totally-sealed structure, an acoustic surface wave sensor tag is placed in the arc extinguish chamber, an acoustic surface wave receiver is arranged outside the arc extinguish chamber, the acoustic surface wave sensor tag is fixed to the wall of the inner side of the arc extinguish chamber, the position of the acoustic surface wave sensor tag corresponds to the position of the acoustic surface wave receiver arranged outside the arc extinguish chamber, and the distance between the acoustic surface wave sensor tag and the acoustic surface wave receiver is within 40 CM. The direction of a transmitting antenna of the acoustic surface wave receiver points to the acoustic surface wave sensor tag. The pressure change condition in the arc extinguish chamber can be monitored by the device, the problem that the effective means for conducting real-time monitoring on the high-voltage circuit breaker arc extinguish chamber of an electric system does not exist for a long time is solved, and the major breakthrough is achieved in the technological means.
