基于光纤灯技术的防火防爆防触电照明系统

电力系统变电站除常规照明外,在电缆夹层等生产场所还装设有防爆型安全电压照明与事故照明等系统,种类繁多、维护复杂,与当前变电站的无人值守及运维一体化生产模式不相适应。基于光纤灯技术的防火防爆防触电照明系统,主要由阳光导入光纤灯照明系统与激光灯导入光纤灯照明系统构成。其室内的光纤灯及其光缆不会带电、不会发热、不会打火,节能环保、寿命长,能够替代变电站现有的各种照明系统,简化了照明系统结构,安全稳定可靠,施工维护便捷,提高了变电站的安全经济运维水平。

Achieving UHF RoF communication based on restraining zero band with EO-FM modulation

We present a simple system of RoF communication based on electronic-optical frequency modulation（EO-FM） in the article. Optical system soflware-Optisystem5.0 was adopted. The results of software simulation showe that the simplex - directional 5 Gbit/s data and UHF microwave of 24 GHz were successfully transmitted over 15 km single mode fiber with 0dBm transmitted power, dispersion is 17 ps/nm/km, attenuation is 0.25 dB/km.
