The Design of the Upper Computer System of the on-line Moisture Content Monitoring of SF_6 Circuit Breaker Based on GPRS

On-line monitoring of moisture content in SF6 circuit-breaker runs on the host computer,the system can be adapted to carries on the real-time monitor to mechanical properties and electrical insulation of SF6 circuit-breaker,and form an timely and accurate judgment.In this paper,according to the characteristics of the moisture content on-line monitoring system for SF6,the system will transmit characteristic values of working condition to the monitoring centre by GPRS wireless communication technology and network platform,so the host computer communicate with the lower computer monitor system is realized,and the on-line monitoring,diagnosing alarms,transmission and other functions of moisture content in many SF6 circuit-breakers are complete.
