基于无源无线SAW的开关柜温度检测系统的研究

Study on the Temperature Detection System of Switch Cabinet based on Passive Wireless SAW

为了对高压开关柜内温度进行有效准确的测量,在对变电站开关柜内环境的要求做出准确判断的基础上,设计了一套基于无源无线SAW温度监测系统,用无线电信号将分散的传感器进行连接,组成设备的温度监测网络,将最终参数信息送至监控中心,以便相关工作人员进行直观的观测。该装置投入到变电站中测试,发现对高压开关柜内的温度能进行准确有效的检测,并能正常发出预警信号,达到了预期目标。

In order to effectively accurate temperature measurement within the high voltage switch cabinet,at the request of the environment inside the substation switchgear make accurate judgment,on the basis of design a temperature monitoring system based on passive wireless SAW,sensors are connected by radio signal will be dispersed,composition of equipment temperature monitoring network,will eventually parameter information sent to the monitoring center,so that the relevant staff for intuitive observation.The device is put into the substation to test,and it is found that the temperature in the high voltage switch cabinet can be detected accurately and effectively,and the warning signal can be issued normally,and the expected target is reached.
