摘　　要：采用双SF6传感器和负高压自适应技术对传统的负电晕放电监测SF6泄露的技术进行改进,应用多种传感器的数据融合技术产生报警信息,有效地提高了SF6传感器的使用寿命,解决了误报警率高的问题.测试表明,该系统满足了高压变电站对开关室内环境状态的在线实时监控的需求.Using dual-sensor and negative high-voltage adaptive technology to improving the traditional monitoring SF6 leak of negative corona discharge technology, applying with multi-sensor data fusion technology to generate alarm information, a high stable SF6 gas online monitoring system has developed. The technology has been applied has effectively improved the life of the SF6 sensor and resolved the problem of the high false alarm rate. The field application has shown that this system meets the demand of on-line real-time monitoring of the chambers＇ environmental status.
