| 摘 要： | 金属氧化物避雷器(MOA)广泛应用于10 kV变电站电力设备的过电压保护,这种避雷器由于使用量大且分布广,导致查找故障点困难,为此研制了变电站用10 kV避雷器运行状态在线检测装置。首先利用EMTP软件仿真得出只有氧化锌避雷器的阻性电流分量才能真实准确地反映出避雷器运行状态,其次介绍了用谐波分析法对MOA的阻性电流进行监测的原理,并设计了一种基于微功率无线通信技术的氧化锌避雷器的远程在线监测系统来实现对MOA状态的实时监控,最后进行了试验分析。

| Abstract: | Metal oxide arresters(MOA) are widely used for overvoltage protection of power facilities in 10 kV substation,and due to its large amount of usage and wide distribution,it is very hard to find the fault point.A kind of 10 kV on-line monitor for MOA used in substation is developed.Firstly,the resistive current component of MOA could accurately reflect the actual state of arrester operation by EMTP simulation.Then the principle of detecting the MOA resistive current by the harmonic analysis method is also introduced,and a remote monitoring system for MOA based on micro-power wireless communication technology is designed to realize the real time monitoring of MOA situation,and finally the test and analysis are carried out. |
