GIS变电站二次设备端口电磁骚扰测量系统的研制及应用

Gaoya dianqi, 2017
在GIS变电站中,大量二次智能单元下放到本地汇控柜或者安装在GIS一次设备附近,例如:电子式互感器、合并单元、智能终端等测量监测设备。它们容易受到开关操作引起的瞬态骚扰电压影响而导致工作异常。为了制定相应的电磁兼容考核要求和防护措施,研究电磁兼容特性,需要通过测量掌握二次设备端口所受电磁骚扰电压特性,则需要满足特定要求的GIS变电站二次端口电磁骚扰测量系统。开关操作引起的二次设备端口瞬态骚扰电压的特点是:高频成分较多,分布在几兆赫至十几兆赫,最高可达上百兆赫;上升沿陡度大,可至数纳秒级;持续时间长 ...

基于光纤传输的高压断路器触头温度测量研究

Gaoya dianqi, 2011
针对高压真空断路器内部的高电压、大电流、强电磁干扰、机械结构复杂的特殊工作环境,提出了基于光纤传输技术的隔离式触头温度实时测量系统。首先阐述了系统的总体结构设计和各模块设计的基本思路,然后从硬件和软件两个方面详细描述了系统的设计过程。系统的实际测试结果表明:该系统能够对高压断路器内多个触头温度进行实时监测并能安全、稳定、可靠的工作;系统安装简便,成本低,功耗小,并具有很高的安全性、实时性、准确性以及抗强电磁干扰能力。
