在电力行业中RTU[1]、DTU[2]、FTU[3]、TTU[4]等设备是配网自动化系统中的开关监控装置,适用于城市、农村、企业配电网的自动化工程,完成环网柜、柱上开关的监视和保护以及通信等自动化功能,配合配电子站、主站实现配电线路的正常监控和故障识别、隔离和非故障区段恢复供电,在电力行业有着广泛的应用。这些设备的内部设计上非常相似,其对电源的要求更是如此,下面以DTU为例介绍其供电电
In the power industry, RTU [1], DTU [2], FTU [3], TTU [4] and other equipment are switch monitoring devices in distribution network automation systems and are suitable for automation projects in urban, rural and enterprise distribution networks. Complete the monitoring and protection of ring counter, column switch and communication and other automation functions, with the distribution of electronic stations, the main distribution line to achieve the normal monitoring and fault identification, isolation and recovery of non-fault section power supply, the power industry has a wide range of Applications. The internal design of these devices are very similar, its power supply requirements even more so, the following to DTU as an example to introduce the power supply
