| 摘 要： | 高压开关触头、母线一般处于高电位,检测其温度一直是电力系统检测中的难题.提出了一种新方法,利用AVR单片机控制光源,通过位移一光强度型光纤温度传感器的调制,带有温度信息的光信号耦合到LOG114芯片进行光电转换及放大,输出信号再由AVR单片机进行A/D转换,经数据分析得到高精度的温度值.系统具有精度高、体积小和抗电磁干扰强等特点.

| Abstract: | Due to the contacts and bus of the hige voltage switchlies in high potental ,it is difficult to detect their temperature directly . A new design is discussed using AVR control led light source . Through light intensity fiber-optic temperature sensor modulation , the optical signal with a temperature informationis coupled into LOG114 for photoelectric conversion and enlarger . AVR processes A/Dconversion for the output signal and analyses data to gain high-precision temperature . The system has characteristics of high precision ,occupied small space ,resistance to electromagnetic interference . |
