针对负电晕放电和电化学气体泄漏检测技术存在的测量实时性差、测量精度低等问题，设计了一种新型的光子晶体光纤SF6气体传感器，利用谐波检测方法和计算机无线传输网络构建远程实时监测系统，实验表明，气体检测的相对误差在2%以内，当SF6体积分数大于10-3时，可实现实时报警并开启风机，具有很好的应用前景。
Leakage of SF6 gas in a lot of electrical equipments is inevitable.Aiming at problems of negative corona discharge and electrochemical gas leakage detection technologies such as bad real-time and low precision of measurement,a new type of photonic crystal fiber SF6 gas sensor is designed and use harmonic detection method and computer wireless transmission network to construct remote real-time monitoring system.Experiments show that relative error of gas detecting is within 2 %,when volume fraction of SF6 is greater than 10-3,real-time alarm can realize and turn on fans,and system has a very good application prospect.
