摘要: 提出了基于气体传感器法的GIS设备内SF6分解产物检测系统设计方案:采用新型过滤装置,以排除气体传感器的固有缺陷交叉干扰;基于气体传感器特点设计了恒定电位电路,以确保传感器信号输出的准确度;实施联合自适应卡尔曼滤波算法,以克服温度、流量对气体传感器精度的影响,解决零点自漂的问题.实验结果表明,本系统结构简单、操作方便、测量精确、响应速度快、抗干扰能力强,可用于现场在线和便携检测.Abstract: A design method of measuring SF6 gas decompositions in GIS based on gas sensor was put forward.A new type of filter was applied for the system to get rid of the inherent defect about cross interference between gas sensors; One special constant potential circuit was designed according to the traits of sensors to insure the exact signal; The adaptive federated Kalman filtering was proved, which could make up the infection about temperature and flux to the sensors, as well as, null shift can be resolved. The practice results showed that the system has the following advantages:simple structure, convenient operation, the measuring accuracy, the quick survey speed, the strong antijamming ability and so on.It can be used to test SF6 gas decompositions on line and portably.
