摘要
国内无线技术与光纤复合架空地线(OPGW)短路电流试验相结合的测试技术一直处于研究空白阶段。根据光功率计和双波长稳定光源的合理搭配,组成满足试验要求的光衰减测试系统;基于ZigBee无线测温技术和数据采集系统的有机结合,组成适用于OPGW-24B1-72样品的短路试验测温系统;通过光衰减测试系统与测温系统的组合,建立一种OPGW短路试验无线温度测试系统并进行试验。试验中样品光缆的最高温度约为161℃,光纤永久最大衰减约为0.01dB/fiber。试验结果证明:基于ZigBee的OPGW短路试验无线温度测试系统不仅具有可操作性,而且能大程度缩短准备时间,提高了在大电流试验现场设备和人员的安全系数,并进一步简化了测试现场的线路布局。
The test technology combining the domestic wireless technology with the optical composite overhead ground wire(OPGW) short-circuit current test has been in the research blank. According to the reasonable combination of the optical power meter and the dual-wavelength stable light source, a light attenuation test system that meets the test requirements is formed. Based on the organic combination of Zig Bee-based wireless temperature measurement technology and data acquisition system, a short-circuit test temperature measurement system suitable for OPGW-24 B1-72 samples is formed. Through the combination of the optical attenuation test system and the temperature measurement system, an OPGW short-circuit test wireless temperature test system is realized and established. After the test, the maximum temperature of the sample cable is about 161℃, and the permanent maximum attenuation of the fiber is about 0.01 dB/fiber. The experiment results prove that the proposed system is operable and greatly shortens the preparation time, improves the equipment and personnel safety factor at the high-current test site, and simplifies the circuit layout of the test site.
