Centralized Type DTU
The centralized DTU adopts high-performance MCU processor, high-speed industrial network communication technology, multi-CPU integration technology and Linux operating system. The product has strong stability, high reliability, good real-time performance, and strong environmental adaptability. Mainly used in the ring network cabinets, switching stations, box-type substations, etc. in the distribution network, combined with the main distribution station, it can quickly and reliably realize the fault location and isolation of the distribution network and the restoration of the power supply in the non-faulty section. It is a kind of new generation of remote terminal device for distribution automation that integrates telemetry, remote control, protection and communication functions.
Description and Functions of Centralized Type DTU
With "communication", it has "remote maintenance" function.
Flexible configuration, all protection functions have separate retreat.
The device has a complete self-checking function to detect the working conditions of each part online.
The closing and closing circuit adopts anti-misoperation design and has anti-missing function.
Applicable to analog acquisition, state quantity acquisition, local and remote control switch closing of 4-12 switch
24 channels can be controlled by expansion
By selecting different configurations, it can meet the needs of “Three Remote” and “Two Remote” of State Grid and South Grid.
Meet the special requirements of all parts of the country (such as Shandong, Beijing, Guangdong, etc.)
Zero-sequence current setting adaptive function, no manual setting required
Meet the specific requirements of “one or two integration”
The core unit can be flexibly configured to shade vertical, shaded horizontal, outdoor vertical and group screen.
