摘　　要：传统的SF6气体的离线测量方式在精确度、实时性等方面存在一定的不足,而且其湿度的标定方法不能准确的反映SF6断路器的运行状态。针对以上问题,本文设计了一种基于GPRS网络的SF6断路器微水在线监测系统,并详细论述了该系统结构、工作原理,重点研究了变电站现场条件下压力、温度与SF6气体相对湿度的关系,设计和实现了一种微水整定算法。经过实际应用检验,该装置可实现变电站内SF6气体状态的实时在线监测,采用在线监测相对湿度的方式,相对提高了采集的准确性,有效保证了设备的安全运行。There is a certain lack of the accuracy and real-time in the traditional off-line measurement of SF6 gas,and its humidity calibration method does not exactly reflect the operational status of SF6 circuit breaker.Due to the problems,the paper introduces a on line monitoring system of moisture content in SF6 circuit breaker.It explains the structure of system and the principle of work,especially the influence of pressure and temperature on moisture content.By the comparison between this system and the measurement devices at home and abroad,this system realized the online monitoring of SF6 gas in substations,and the rate of information＇s sharing and applying is promoted.
