摘要
新能源场站中关键一次设备内部电缆接线端子、变压器高低压侧端子等温度在线监测设备存在需更换电池、破坏设备绝缘结构、无法接触发热点、通讯故障率高、可靠性差等问题.文章介绍了RFID无线无源测温技术原理,探究了该技术在新能源场站开关柜、环网柜及箱变中的测温方案,并通过在三峡乌兰察布新一代电网友好绿色电站示范项目中的实际应用,验证了该RFID无线无源测温技术的有效性.
Abstract
The online monitoring technology for the temperature of key primary equipment internal cable connection terminals,transformer high and low voltage side terminals,etc.in new energy stations has problems such as the need to replace batteries,damage to equipment insulation structures,inability to contact hotspots,high communication failure rates,and poor reliability.The article introduces the principle of RFID wireless passive temperature measurement technology,explores the temperature measurement scheme of this technology in switch cabinets,ring main units,and box transformers of new energy stations,and verifies the effectiveness of the RFID wireless passive temperature measurement technology through practical application in the"Three Gorges Ulanqab New Generation Grid Friendly Green Power Station Demonstration Project".
