Abstract

Abstract:

In order to protect the LHW antenna, it is necessary to measure the antenna temperature. According to the antenna specifications, the K type thermocouple is selected as the measurement tool. The signals generated by 8 thermocouples are acquired by a temperature logging device with high speed, and the measurement data are read remotely by software for display. Fiber communication is adopted to resist the EMI brought by tokamak in the loop of measurement hardware. The test results show that this method is able to real time reflect the trend of antenna temperature accurately, which lays a foundation for further antenna thermal protection.

摘要：

为了实现对低杂波系统天线的保护需要测量天线温度，根据天线的特征，选择了K 型热电偶作为测量工具，使用快速温度巡检仪采集8 路热电偶信号，温度数据由软件远程读取显示；为了克服托卡马克带来的电磁干扰，测量回路使用了光纤通信的方法。结果表明，这种方式能够准确实时地反映出天线温度变化，为日后开展天线热保护工作奠定了基础。
