转子水内冷机组运行时,需监测各磁极出水端温度。中国科学院电工研究所和响洪甸水电站合作,于82年4月用无线电遥测技术测量了转子温度。经过140小时连续监测表明:发射、接收、同步装置工作稳定;克服了电机运行时产生的电磁干扰;测量数据重复性好。由于测量装置旋转部分的供电取自发电机励磁电源,不用任何滑环就能长期工作,实现温度的无触点测量。遥测系统方框图如下: Rotor water cooling unit operation, the need to monitor the temperature of each pole water outlet. The Institute of Electrical Engineering, Chinese Academy of Sciences, in cooperation with Xiang Hongdian Hydropower Station, measured the rotor temperature by radio telemetry in April 82. After 140 hours of continuous monitoring shows that: launch, receiving, synchronization device work stable; to overcome the electromagnetic interference generated when the motor running; measurement data repeatability. As the measuring device rotating part of the power supply from the generator excitation power supply, without any slip ring can long-term work to achieve the temperature of non-contact measurement. Telemetry system block diagram is as follows:
