摘　　要：分析特高频监测传感器特点及其受GIS内部不同结构的影响,针对具体外置传感器性能,研究并提出体现效能与成本平衡的传感器测点布置策略。该策略中,监测传感器在GIS模型及实体间隔内模拟局部放电,统计分析实验样本数据,讨论GIS内部结构及外部干扰对监测效果的影响,比较各类情况下传感器在盆式绝缘子法兰处的检测效果。该策略兼顾对关键设备局部放电信号的有效监测和配置经济原则,有利于为放电源定位提供依据。This paper analyzes the characteristics of UHF sensor and the effects of GIS interiorstructure on it. The layout strategy of the test points of UHF sensor is studied and proposed. Inthe strategy, the monitoring sensor simulates partial discharge in GIS model and entity interval.The sample data is analyzed, based on which the effects of GIS interior structure and externaldisturbance on the monitoring effects are studied, and the monitoring results of in various sensorbasin-type insulator flanges are compared. The strategy considers both the effective monitoring onpartial discharge signals of the key devices and the economical allocation, and it helps to providethe basis for discharge source location.
