摘　　要：为了及时发现交流特高压避雷器的受潮、老化和其他隐患,避免因事故造成巨大经济损失,对特高压避雷器在线监测系统进行了研究。该系统采用性能稳定、功耗低、体积小,可靠性高的传感头采集流过避雷器的全电流信号;电流信号采用光纤传输;传输信号由信号处理单元处理后通过RS485发送至PC机,在PC机内通过程序对采集的数据进行处理,并通过人机界面进行自动判断与数据存储,从实验室的运行情况看,该系统可以满足特高压避雷器在线监测的要求。In order to detect the AC ultra high voltage surge arrester＇s moisture, aging, and other risks, to avoid big economic losses caused by the accident, The ultra high voltage surge arrester on-line monitoring system is studied. The system uses stable performance, low power consumption, small size, high reliability of the sensor to capture the signal which is full current flowing through the arrester. The current signals is transmissed by optical fiber. The signal processed by the unit which processes the signals is sent to the PC by the RS-485 protocol. The data which is transmissed is processed by the program in the PC and the data is stored automatically and judged automatically through the man-machine interface. From the operation of the laboratory situation, the system can meet the ultra high-voltage surge arrester＇s on-line monitoring requirements.
