| 摘 要： | 高压开关触点、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。针对这一问题,笔者提出了一种结合光纤技术的检测方法,利用AVR单片机控制光源,通过光强度型光纤温度传感器的调制,将带有温度信息的光信号耦合到LOG114芯片进行光电转换,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。结果表明,该系统具有精度高、体积小、易安装等特点。

| Abstract: | For directly detecting temperature of the contacts and bus of high voltage switch,this paper presents a detection method by making use of fiber-optic technology.An AVR microcontroller is adopted to control light source,the optical signal with temperature information is coupled into LOG114 chip for photo-electric conversion through modulation via light intensity type optical fiber temperature sensor,and A/D conversion of the output signal is then performed by the AVR microcontroller to obtain high-precision temperature values through calculation.The system has the features of high precision,small volume,and easy installation. |
