Purpose

DTU series distribution network automation terminal device is a protection and monitoring terminal product developed for multi line collection places such as ring main unit and small switching station in distribution network

The current and voltage acquisition of main control unit in DTU device adopts ad special high-speed sampling chip, and the device adopts 32-bit MCU control chip at the same time. It is a new type of high-voltage switch control device, which can quickly and stably complete the monitoring of high-voltage switch. It integrates the functions of protection, measurement, control, monitoring, communication and movement, and has the characteristics of high integration, flexible configuration and friendly interface. It is widely used in radial power supply and ring network power supply system, which can help the system identify the transient fault and permanent fault of the line, automatically eliminate the impact of the transient fault on the line, isolate the permanent fault section, avoid long-term large-area blackout, and automatically restore the power supply of non fault section, so as to realize the automation of distribution network economically and practically

Functional features

Unified core public platform: using embedded real-time operating system, supporting high-speed Ethernet bus and can bus, large interface capacity.

Communication mode, communication protocol diversified configuration: hardware configuration independent communication management module, hardware configuration support main standby exchange, redundancy design. The software configuration supports a variety of communication modes (Ethernet, GPRS, optical fiber, etc.) and a variety of communication protocols (such as more than 50 kinds of GB101, gb104, Mudbus, etc.), and can communicate with multiple master stations of different levels at the same time. The flexible configuration of remote communication, remote control and telemetry: the number of three remote functions can be configured according to the needs of the project, and the real modular design.

Intelligent power management: multiple power supply, support battery switching of various media and capacity, intelligent battery management (automatic battery activation), output voltage and power of operation power supply are monitored and displayed, with perfect overload and short circuit function, backup power provided by battery is online hot backup

Convenient maintenance function: provide remote and local maintenance interface, operators can maintain it locally or in the main station. Support handheld wireless maintenance, can be convenient

Flexible and convenient strategy configuration: current type DA, voltage type DA, composite type DA

The modular design of the system can support the use of various specifications of the loop, up to 18 loops.
