摘　　要：六氟化硫(SF_(6))气体分解产物检测对于气体绝缘设备的故障评估和电力系统的安全监测具有重要意义。文中提出了一种基于SnS_(2)纳米材料气体传感器检测SF_(6)分解产物的方法,即采用水热法和丝网印刷法分别制备SnS_(2)纳米材料和气体传感器,通过实验研究了该传感器对SF_(6)分解产物H_(2)S和SO_(2)F_(2)气体的最佳工作温度、响应特性、灵敏度和长期稳定性。测试结果表明,SnS_(2)气体传感器在最佳工作温度200℃下,对两种SF_(6)分解气体产物的响应与其体积分数之间线性关系较好,线性相关系数均大于0.980,且稳定性较好。文中研究可为SnS_(2)基气敏传感器检测SF_(6)分解组分提供数据参考。The detection of sulfur hexafluoride(SF_(6))gas decomposed products is of great significance for fault assessment of gas insulated equipment and safe monitoring of power system.In this paper,a kind of method to detect SF_(6)decomposed product by SnS_(2)nanomaterial-based gas sensor is proposed,namely,using the hydrothermal method and silk screen printing method are used to prepare SnS_(2)nanomaterial and gas sensor respectively.The optimal operating temperature、response characteristic、sensitivity and long term stability of the sensor to H_(2)S and SO_(2)F_(2)gas,the SF_(6)decomposed product,is studied experimentally.The test results show that the SnS_(2)gas sensor has a good linear relationship with the response and volume fraction of the two SF_(6)decomposed gas products at the optimal working temperature of 200℃,and the linear correlation coefficients are greater than 0.980 with good stability.The research in this paper can provide data reference for the detection of SF_(6)decomposed components by SnS_(2)-based gas sensor.
