The terminal of the secondary and converged SMS500 distribution network automation station is mainly used for monitoring the opening and closing station, switch station, cable dividing room, ring network cabinet and power distribution room, low voltage substation and other places.
1) High-precision, wide-range sampling, conforming to the Comtrade 1999 standard for high-precision 128-point recording.
2) Small current single-phase ground fault, using the transient algorithm to solve the single-phase ground fault location and isolation in situ.
3) Deepen the localized feeder automation application, compatible with recloser voltage time type, voltage and current time type, and adaptive integrated type.
4) Access the line loss measurement module to improve the level of management refinement.
5) Communication can be hard and soft encryption, built-in national network professional security chip.
6) The communication protocol is expanded, and it has the function of configuring the national remote unified parameter.
7) Complete cascade channel, 6 RS232/RS485 serial ports that can be switched on site, and 2 RJ45 networks, which can meet complex site requirements.
8) Relevant type tests, one-time integration professional inspection, special inspection of national network, and information security special items have been obtained.
