摘　　要：绝缘故障是六氟化硫电气设备的主要故障之一。提出了一种基于模糊证据理论的六氟化硫电气设备绝缘性能识别新方法,通过评判六氟化硫电气设备绝缘水平的4个主要特征量去判别其绝缘性能。运用证据理论实现对不同特征量之间的信任分配函数的两两融合。实验结果表明,该方法能有效地判别六氟化硫电气设备绝缘性能状况。Insulation fault is one of the main faults of sulfur hexafluoride electrical equipment. A new method for identifying the insulation performance of sulfur hexafluoride electrical equipment based on fuzzy evidence theory is proposed,that is,the insulation performance of sulfur hexafluoride electrical equipment is evaluated by four main characteristic quantities of its insulation level.The evidence theory is used to realize the pairwise fusion of trust distribution functions between different feature quantities. Experimental results show that the proposed method can effectively determine the insulation performance of sulfur hexafluoride electrical equipment.
