摘要
针对GIS设备内部可能发生局部放电的问题,以及市场上现有的GIS局部放电监测设备成本高昂且不能做到实时监测的缺点,设计了一套基于UHF法的GIS局部放电报警系统,该系统具有成本低、实用性强等优点,可以将其固定安装在GIS设备上实现实时监测。仿真和实测结果表明,该设计解决了信号数字化模块的设计问题,验证了设计方案的可行性。
Since partial discharge may happen inside the GIS device and devices monitoring GIS partial discharge on the market are not only expensive but also non-real-time,an alarm system of GIS partial discharge is designed,which has the advantages of low cost,strong practicability and it can be fixed on the GIS device to realize real-time monitoring. According to the simulation and experiment results,the problem of the signal digitizing module of the system that is the use of high speed integrated comparator has been solved,simultaneously,the feasibility of the system has been proved.
