采用无线RF技术的高压开关柜实时测温系统

Real-time Temperature Measurement System of High Voltage Switchgear by RF Wireless Technical

高压开关柜开关触头发热是常见的故障,为解决发热的监测问题,已进行了多年研究。采用无线技术的开关柜实时监测系统是一项新成果,己在金华江南变电站等处投入运行。其测量部分能直接安装在高压带电部分,实现等电位工作,解决了高压绝缘问题,且测量和通信部分体积小、重量轻、安装灵活方便,适用于各种类型的开关柜,可为开关柜触头及其它设备发热故障的实时监测发挥作用。

The disconnecting switch contacts fault of high voltage switchgear is familiar. In order to resolve monitoring problem, the study has been already carried on for many years. A real-time monitoring system of switchgear by wireless technical is a new study result. The system has been running in Jiangnan substation and etc. The measuring part can be direct installed at living part of high voltage switchgear for equal potential working, and resolve high voltage insulation problem. Its measuring and communicating parts are small physical volumes, light weight, convenience install. It can be applicable to the various type＇s switchgear. The system can exert on a role in real-time monitoring of over-heat fault for disconnecting switch contacts and other equipments.
