摘　　要：针对现有GIS局部放电检测设备的缺陷,设计了一种基于无线传感器网络(WSNs)和GSM的GIS局部放电报警系统。GIS局部放电报警系统由一个信息中转站和若干个传感器节点组成,传感器节点获取GIS工作状况信息,通过nRF24l01无线模块将信息发送给信息中转站,信息中转站再利用GSM模块将各传感器节点发来的信息发送给GIS站管理员,实现了对GIS局部放电高效的实时在线监测。测试实验结果表明:该系统简单、经济、工作稳定、监测范围广,当GIS发生局部放电时,系统能准确地发出报警信息;传感器节点使用1000 m Ah的锂电池供电可持续工作超过211天,信息中转站采用20 Ah的铅酸电池供电可持续工作超过58天。Aiming at disadvantages of existing GIS partial discharge detection equipment, an alarming system based on GSM and WSNs for GIS partial discharge is designed. GIS partial discharge alarming system consists of an information transfer station and some sensor nodes. Sensor nodes obtain GIS＂ working status information and send the information to the information transfer station by nRF24101 wireless module, then the information transfer station sends information to GIS station manager through GSM module, which realize efficient and real-time online monitoring on GIS partial discharge. Test results show that the system is simple, economical, stable and extensive in monitoring range, when GIS partial discharge occurs, the system can accurately send alarm information;sensor node is powered by 1000mAh lithium battery, which can continue to work for more than 211 d and information transfer station is powered by 20 Ah lead-acid battery ,which can continue to work for more than 58 days.
