针对目前高压配电装置隔离触头温度在线监测因采用红外探头、光纤等监测手段存在造价高、安装不便、测试不准确等问题,设计了一种基于nRF905的高压配电装置隔离触头温度在线监测装置,详细介绍了装置的硬件和软件设计。实验结果表明,该装置数据采集、数据收发和数据处理单元的电路设计合理,装置能比较准确地对高压配电装置隔离触头温度进行在线监测,测量误差为±1.5℃,符合工程实际需求。

In order to solve the problems of high cost,un-convenient installation and low-precise detection caused by using IR temperature sensor and fiber sensor to detect temperature of isolators in high-voltage distribution equipment at present,an on-line monitoring device of temperature for isolators in high-voltage distribution equipment based on nRF905 was designed,and design of hardware and software of the device was introduced in details.The experimental results showed that circuits of data collection,data receiving and sending and data processing of the device are reasonable,and the device can realize on-line monitoring of temperature of isolators in high-voltage distribution equipment,which has error below（± 1.5 ℃） and meets actual needs of engineering.
