摘要
SF6气体密度继电器作为SF6电气设备的重要监控元件之一,预试规程对其检验周期有明确规定,但在实际检验中,发现部分检验人员对密度继电器的相关知识缺乏,影响检验工作正常开展。文章通过对SF6气体密度继电器的结构、动作原理、精度等级、温度-压力换算及高海拔地区检验方法的介绍,力图提高密度继电器的检验水平。
SF6 gas density relay is one of important monitoring component of SF6 electrical equipment,the inspection cycle has clearly defined in the pre-test regulation.But in actual testing,part of the inspectors lack of related konwledge of density relay,and it affects the inspection work regular development.The paper introduces SF6 gas density relay's structure,action principle,accuracy class,temperature-pressure conversion and the inspection method of high altitude,in order to improve the inspection level of density relay.
