摘　　要：为了及时发现气体绝缘金属封闭开关设备(Gas Insulated Swithear,GIS)放电故障,通过分析GIS设备的典型局部放电检测方法的数据特点,依据模糊综合评价法原理,选取能够反映GIS设备运行状态的检测数据作为评估指标,建立GIS盆式绝缘子的状态评估模型,分析局部放电检测方法;根据相关技术规范对评估指标进行归一化,分析指标数据特征;选择三角形与半梯形组合隶属度函数,运用层次分析法确定评估指标的权重向量集,选择加权平均型算子进行模糊合成,最终实现对GIS盆式绝缘子的状态评估。最后通过实例验证了该评估方法的有效性和实用性。In order to find the fault of the discharge of gas insulated swithear(GIS),this paper analyzes the data characteristics of the typical partial discharge(PD)detection method of GIS equipment,and based on the principle of fuzzy comprehensive evaluation method,the paper selects the detection data that can reflect the running status of GIS equipment as the evaluation indicators.The state evaluation model of GIS basin insulator is established,and the partial discharge detection method is analyzed.According to the relevant technical specifications,the evaluation index is normalized,the index data characteristics are analyzed and the triangular and semi⁃trapezoidal combination membership function is selected,the analytic hierarchy process(AHP)is used to determine the weight vector set of the evaluation index,the weighted average operator is selected for fuzzy synthesis,and the status evaluation of GIS basin insulator is finally realized.An example is given to verify the effectiveness and practicality of this method.
