基于自适应神经模糊推理系统的避雷器有效运行寿命估计方法

Gaoya dianqi
估算金属氧化物避雷器的使用寿命一直是一项挑战，它决定着输电系统的安全稳定运行。基于此，文中提出了一种基于自适应神经模糊推理系统（adaptive neuro-fuzzy inference system，ANFIS）和支持向量机回归（support vector machine for regression，SVR）组成的组合时间序列预测模型，用于估算金属氧化物避雷器（metal oxide surge arrester，MOSA）的使用寿命。首先，文中进行了现场测量 ...

Investigations on Electro-Thermal Ageing of Metal Oxide Surge Arrester Elements: A Realistic Laboratory Simulation

, 1991
The ageing of metal oxide surge arresters (MOSA) under field operating conditions caused by a combination of electrical and thermal stresses is simulated in the laboratory in an attempt to characterize the degradation phenomena as well as to identify the

Studies of in-service and laboratory failures of metal-oxide distribution surge arresters

, 2003
We describe the findings from tests and inspections of arresters withdrawn from service, the results of laboratory studies with multipulse lightning currents and high temporary over-voltages, and comparisons of in-service and laboratory failure modes. We
