摘要
变电站避雷器作为电力系统的重要组成部分,对站内设备起到了很好的保护作用。为对变电站避雷器的运行环境进行有效监测,设计了一套变电站避雷器底座绝缘电流在线监测系统。通过改造底座物理架构,在绝缘底座采用多个传感器检测电流,利用数据融合算法实现检测结果和检测数据的融合,从而当检测值超过系统设定阈值时自动启动现场报警和远程GSM短信报警,实现避雷器的远程在线监测。现场模拟试验数据表明,该系统能够有效实现避雷器的全方面检测,能够预知避雷器装置的安全风险。
As an important part of the power system,the lightning arrester in the substation plays a very good role in protecting the equipment in the substation.In order to effectively monitor the operation environment of the arrester in the substation,an on-line monitoring system for the insulation current of the arrester base in the substation is designed.Through the transformation of the physical structure of the base,multiple sensors are used to detect the current in the insulating base,and the data fusion algorithm is used to realize the fusion of the detection results and the detection data,so that when the detection value exceeds the threshold set by the system,the on-site alarm and the remote GSM SMS alarm are automatically started,and the remote on-line monitoring of the arrester is realized.The field simulation test data show that the system can effectively realize all-round detection of arresters,and predict the safety risks of arresters.
