摘要
采用双电源管理技术设计了输变线路接头的无线测温节点,并通过单片机工作模式的切换实现了测温节点的超低功耗;控制室主机与测温节点通过点对多点轮询模式实现变电站的无线测温与通信。无线测温装置安装在高压变电站环境中,进行了两个系统之间的电磁兼容性分析。系统在天津市供电公司西青供电分公司变电站试运行1年,证实了其有效性。
Fire and explosion occurred at transmission circuitry joints in high-voltage transformer substation caused by high temperatures were frequently accompanied by huge financial loss. Double battery technique was applied to design a kind of wireless thermometric node, and ultra low power consumption was realized by switching work patterns of chips on the nodes. The host computer in control room utilized roll polling mode to the temperatures of the spots. In respect that the temperature detecting nodes were fixed in high voltage transformer substations, the electromagnetic compatibility （EMC） was studied. This system has been successfully operated in Xi＇qing branch, Tianjin electric power company for 1 year, improved the validity of the design.
