On the basis of the present technologies of sulfur hexafluoride(SF6)leakage detection,in order to detect whether the SF6 breakers leak and the concentration of SF6 in the room timely and correctly,an fiber-optical SF6 infrared gas sensor and the system of SF6 gas leakage detection was designed by using the method of infrared absorption spectrum.

为了更加及时准确地检测SF6断路器的泄漏情况以及气室内SF6气体的体积分数,在分析了现有SF6断路器检漏技术的基础上,主要利用红外吸收光谱法,设计出了全光纤光学式SF6红外气体传感器及SF6气体体积分数检测系统。
