金属氧化物避雷器的固有参数及其当前性能的评定

INHERENT PARAMETERS OF MOA AND ITS PERFORMANCE EVALUATION

本文介绍了金属氧化物避雷器固有参数的计算方法，找出了固有参数与在线检测数据之间的关系。本文述及两个方面：一是固有参数（Ｂ、β及Ｃ）的计算问题；Ｍ是根据标准评价运行中的金属氧化物避雷器的特性问题。推导结果表明：在运的金属氧化物避雷器的性能可以借助于实时检测到的数据与性能指标间的对应关系通过计算机来实现实时监视。

A method of calculating the inherent parameters of MOA used in power system to restrict the surge voltage is presented. The purpose of this research is to determine he relation between inherent parameters of MOA and its data from on-line detection. Two problems are discussed in this paper, one is the calculation of the on-line in-herent parameters (B, 5 and C) of MOA, the another is the evaluation of performance of MOA according to the con-cerned standard. The result of measurement and test shows that the performance of a running MOA can be monitored by a computer when the data from real-time detection are registered.
