Distributed Type DTU
The distributed DTU power distribution terminal is suitable for the protection, measurement and control, and communication of the interval unit of the ring network cabinet with a voltage level of 10kV and below. Equipped with complete protection, measurement, control and communication monitoring functions, the mcc main control cabinets electrical cooperates with circuit breakers, load switches and other switches to provide protection for lines and feeder lines of 10kV and below, using complete protection functions to quickly isolate and isolate fault areas and reduce power outages Range, rapid restoration of power supply, and a strong guarantee for the safe and stable operation of the distribution network system.
Features of Distribution Automation Terminal
Distributed structure, it composed by several interval units and public units.
The software platform adopts the powerful Linux operating system of real-time multi-tasking and multi-threading.
The rtu remote terminal unit can record the first 4 cycles of the faulty line and 8 cycles after the failure during the fault recording of the device, and record 64 points for each cycle. Use the device maintenance tool to perform detailed analysis on the recording files, and the waveform details can be seen at a glance.
Miniaturization, each unit of the terminal adopts a small structure, and the structure is small and convenient for mass production and mass testing
The installation is simplified, and the terminal adopts a unified and easy-to-plug interface, suitable for installation and replacement
Large size LCD screen with 160*160 resolution, terminal operating conditions can be seen at a glance
It has a variety of communication interfaces and a variety of standard communication protocols. In addition to the internal data management function, it can also forward the data of electricity meters, PLC and DC screen in the distribution room or on and off station, and complete the data transmission and other functions by communicating with the master station system through a standard unified interface
Main Purpose of Distribution Automation Terminal
Installed in conventional switching stations (stations), outdoor small switching stations, ring main unit, small substations, box-type substations, etc., to complete the position signal, voltage, current, active power, reactive power, and collection and calculation of electric energy and other data, etc., to perform opening and closing operations on the switch, to realize the fault identification and isolation of the feeder switch and the restoration of power supply to the non-fault section. Report the processing process and results to the main distribution automation station.
Advantages of Distribution Automation Terminal
Use miniaturized distributed DTU to transform the existing ring main unit, which greatly saves installation space and solves the problems of large installation volume, complicated wiring, and long power outage time and so on.
It does not depend on the global information of the master station or the sub-station
Fast processing and reliable action
When the operation mode of the distribution line changes, the logic is adaptive.
No need to reclose multiple times, reducing the impact on the equipment.
