摘　　要：针对检测GIS(Gas Insulated Switchgear,简称GIS)局部放电的分布式传感器采集局部放电信号的数据量大,通过RS-422串口进行数据传输时间长的不足。基于GIS局部放电分布式传感器在线监测系统,采用一种最大值数据压缩算法,将高速A/D采集到的大量实时数据,有效地传输到后台监测系统,解决了分布式在线监测系统中大量数据传输的瓶颈。通过实验验证,该数据传输方式速度快,性能安全、可靠,实用性强。In view of the disadvantage that the data transmission through RS-422 serial port needs a long period because the large amount of partial discharge signal data are collected by the distributed sensors for detection of GIS（ Gas Insulated Switchgear） partial discharge,a maximum data compression algorithm is adopted in the on-line monitoring system of GIS partial discharge based on distributed sensors in this paper. By the proposed algorithm,a large number of real-time highspeed data collected by A/D can be transmitted to the background monitoring system effectively. Therefore,the bottleneck problem of the large number of data transmission is solved. The experimental verification shows that the proposed data transmission mode of the system is fast,safe and reliable with a good practicability.
