摘要
研究利用单只发光二极管(LED)和高阻值电阻串联而成的电压传感器及其温度漂移补偿方法。通过将输出传感信号的交流、直流分量相除的运算,可以实现传感信号温度漂移的实时补偿。实验测量了1. 35 kV^4. 5 k V范围内的工频电压,在-40^+60℃的温度范围内,电压传感信号的温度漂移低于±2. 9%。
An optoelectronic voltage sensor composed ofmonochromaticlight-emitting diode(LED)and a resistance is investigated in experiment,in order to compensate for its temperature drift of output sensing signal.The temperature compensation can be achieved by the division operation between the alternating and direct components of the output signal.The 50 Hz measurand voltage in the range of 1.35~4.5 kV has been measured,and corresponding temperature drift is less than(2.9%in temperature range of-40^+60℃.
