摘　　要：通过理论和试验统计数据分析,指出了在线监测检出金属氧化物避雷器故障的有效性。基于形态学理论,构造了适用于在线监测数据处理的开-闭、闭-开和混合滤波器,并通过仿真计算验证了形态学滤波器的有效性。建立了金属氧化物避雷器本体温升、全电流、阻性电流、外观等状态量的评价函数,并通过引入状态量的权重因子获得了在线监测的评价模型,该模型可以对运行中的金属氧化物避雷器进行有效评价。Through the analysis on the theoretical and test ing of metal oxide arrest （MOA） malfunction is verified. statistical data, the effectiveness of online monitor- Based on the mathematical morphology theory, the open-closing filter, close-opening filter and hybrid filter for online monitoring data processing are constructed. The effectiveness of the filters is also validated through the simulation and calculation. The evaluation func- tions of quantity of state including body temperature rise, total current, resistive current, appearance etc. are established and the evaluation model of online monitoring of MOA is created by introducing the weighting factor of quantity of state. This model can perform effective evaluation of MOA in operation.
