CKPM602 distribution automation terminal (hereinafter referred to as DTU) is suitable for distribution networks with voltage levels of 10kV and above. It can be applied to distribution automation systems with double-ended power supply, open-loop or closed-loop operation. The device is the terminal of the box-type distribution automation station, and completes the local and remote monitoring, control and fault detection functions of the switchgear through the current, voltage, state quantity, etc. of each line in the station.
The terminal has the functions of voltage-time type and other on-site feeder automation, inter-phase short-circuit fault protection and ground fault protection tripping functions, single-phase grounding adaptive fault judgment tripping function, and three-phase automatic reclosing function. The terminal can be used as a traditional distribution automation terminal product, or as a primary and secondary integrated distribution automation terminal product.
Three remote function; Flexible configuration configuration function to achieve DTU three remote function, low pressure measurement and control function; Three remote function; With telemetry, remote communication, remote control, communication and other conventional monitoring and control/telecontrol functions;
Reasonable structure; Insert plate installation structure, intuitive operation instructions, flexible application configuration, components interchangeability, convenient maintenance;
Intelligent data; each plug-in module has its own intelligent unit, and each module exchanges data based on the communication bus; it has the function of historical data storage, records telemetry and SOE data, and the data storage time of the FTU feeder terminal is not less than 1 month;
Maintenance function; complete feeder protection function and fault recording and broadcasting function; collect and identify feeder fault current and transmit it to the substation or master station; can accommodate voltage and current collection of up to 24 loops, with overcurrent, zero sequence current, and overvoltage , Reclosing and other fault detection/protection functions;
The performance is stable; the frequency sampling and tracking technology combined with software and hardware provides a theoretical basis for fast FFT transformation. Sampling accuracy.
Intelligent diagnosis; with self-diagnosis, self-diagnosis for each functional board and important chip;
