| 以声表面波（SAW）器件作为传感器，结合无线智能读写装置，实现传感信息的采集与传输，传感器安装在被测点上，无需连线即可将被测点的温度信息传送出去。而传感器本身无需电源供电、亦无需从电力装备上取电，因而具有优越的安全性、可靠性和可维护性。该技术属于高电压设备安全在线监测方面一项颠覆性技术，是智能电网高压设备实时温度检测技术上的重大突破。近年来已得到国内外在线监测设备厂家和电网公司的密切关注。 For surface acoustic wave (SAW) devices as sensors, combined with wireless smart to read and write device, sensor information acquisition and transmission, the sensor on the measuring point installation, will be the temperature of the measuring point without attachment transmit information. And the sensor itself does not need power supply, nor does it need to take electricity from the power equipment, so it has superior security, reliability and maintainability. The technology is a disruptive technology in the on-line monitoring of high-voltage equipment and is a major breakthrough in the real-time temperature detection technology of the intelligent power grid. In recent years, we have received close attention from both domestic and international online monitoring equipment manufacturers and power grid companies. 主要特性： Main features: 无线传送温度信息 Wireless transfer temperature information 无需电池及取电装置 No batteries and no electricity 无IC电路 No IC circuit 体积小、重量轻、安装简易 Small size, light weight and easy installation 不受高温、高电压、强电磁场环境影响，可靠性高 Low temperature, high voltage, strong electromagnetic field environment, high reliability 实时在线，测温精度高 Real-time online, high temperature measurement 工作温度范围宽 The working temperature range is wide 工作寿命长达20年以上 More than 20 years of working life 安装后几乎终生免维护 The installation is almost lifelong maintenance 测温技术比较 The temperature measurement is compared 传统的测温方式有很多种。当前应用较多的主要有光纤测温、红外测温、无线有源测温、无线感应取电测温等几种。但是，跟基于SAW技术的无线无源测温相比，这些测温方式在电力设备的应用上都有比较大的局限性。SAW测温技术在安全性、耐高温能力和抗电磁干扰能力上有着突出的优势。 There are many different kinds of temperature measurements. The current application is mainly of optical fiber measuring temperature, infrared measuring temperature, wireless active temperature, wireless induction temperature and so on. However, these temperature measurements have a significant limitation on the application of power equipment, compared with the wireless passive temperature measurement based on SAW technology. SAW temperature technology has outstanding advantages in safety, high temperature resistance and anti-electromagnetic interference ability. |
