|
摘要
智能开关是智能变电站的核心设备,是支持智能电网优化运行的关键设备,传感器与智能组件可靠性是衡量智能开关质量的重要指标之一。以1 100 kV智能气体绝缘全封闭组合电器(GIS)为研究对象,搭建暂态地电位测试平台,提出智能GIS的暂态地电位测试方案,通过实测数据研究隔离开关操作引起的暂态地电位抬升对SF_6气体传感器的影响,并提出了压敏电阻、磁环及隔离滤波等多种电磁干扰防护措施,通过试验表明所提出的防护措施效果明显。
Intelligent switch is the core equipment of a smart substation and the key equipment for supporting optimal operation of the smart grid.The reliability of the sensor and intelligent components is one of the important indexes for measuring the quality of the intelligent switch. Taking 1 100 kV intelligent gas insulated switchgear( GIS) as research object,this paper discussed the setup of a transient earth potential test platform and proposed a test scheme for the transient earth potential of the intelligent GIS. Through measured data,it studied the influence which was produced by the transient earth potential rising caused by the disconnecting switch operation upon the SF_6 gas sensor. Furthermore,it proposed various protection measures for electromagnetic interference such as varistor,magnetic ring and isolation filtering. Experimental tests indicated that the proposed protection measures could achieve good effects.
