介绍一种基于冷镜露点法测量技术、热导传感器技术和电化学传感器技术等手段,实现多参数快速测量的互感器带电检测系统,同时考虑检修人员现场取气工作的安全防护等因素,提出了标准化取样接口,简化操作,规范流程。从而建立了SF_6气体绝缘互感器状态安全评价体系。

This essay introduced an electrical transformer detection system that can measure multipleparameters in a fewminutes. The system i based on technologies including chilled mirror dew point thermal conductivity sensor and electrochemical sensor technology. Meanwhile,it considers the safety of themaintainers when collecting gas samples on site. Thereby a safety assessment systemof SF6 was established standardizing the process and simplifying the operation.
