Reliability of Automated Crimping Meter Temperature Monitoring System

摘要:

提出了一种基于双套管结构光纤光栅封装探头形式,研究了基于该封装探头形式下光纤光栅测量温度的同时屏蔽外力影响;在电能表压接触头上布置双套管结构光纤光栅测温探头,通过光缆及光学分路器将传感器连接,并通过主光缆接到控制室的光纤光栅解调仪上,再通过监控软件对信息进行处理,从而构建了电能表压接温度监测系统;研究表明该系统不仅满足强电磁场环境下对温度监测实时性和精确性的要求,还可以屏蔽外部应力对温度监测的影响;温度监控软件对实时的温度信息处理,可以实现温度的图形显示、列表显示,超温时的报警显示等功能。

Abstract:

A double pipe structure based on fiber Bragg grating sensor encapsulated form of the probe was proposed, Which was based on the form of packaged FBG temperature measurement at the same time shielding external influence.In contact with the head pressure meter double pipe structure layout FBG temperature probe, cable and optical splitter through the sensor is connected via fiber optic cable to the main control room of the fiber grating demodulation instrument, and through monitoring software information processing, in order to build a power meter crimping temperature monitoring system. Studies show that the system not only meets the strong electromagnetic environment temperature monitoring real-time and accuracy requirements, you can also shielded from external stress on the impact of temperature monitoring. Temperature monitoring software for real-time information processing temperature, the temperature can be achieved graphical display, the list display, over-temperature alarm display.
