DNEC 0.4/20 Intelligent Midline Protection Device

End-Use Power Protection and Management System

Product Introduction:

The End-Use Power Protection and Management System (DTDS) is an intelligent system designed for comprehensive management, protection, and detection of end electrical circuits. Utilizing the latest hardware architecture and control systems, it features powerful data analysis and real-time tracking capabilities. It can quickly compensate for voltage surges or sags and fluctuations in the end power supply system, control current distribution at the endpoint, and provide real-time voltage protection, current protection, and non-electrical protection for end switching equipment based on the characteristics of end-use devices. According to system settings, it guides maintenance personnel through audible and visual alarms and communication to quickly identify and address issues promptly.

Functional Overview:

The End-Use Power Protection and Management System detects and analyzes end-circuit currents, adhering to the principles of power supply continuity and safety. It manages harmonics and three-phase imbalances, protects precision equipment, eliminates neutral line currents, and provides overcurrent rapid-break protection, definite-time protection, and inverse-time protection for scenarios involving excessive neutral line currents after management.

Overcurrent damage to the neutral line leading to "neutral break" is a severe electrical fault. Moreover, once the neutral line is damaged, not only does the system failure caused by neutral break become critical, but replacing the neutral cable is also very troublesome. Therefore, the terminal has implemented a more comprehensive protection scheme for the neutral line. Under normal operation, the terminal only functions to eliminate neutral line currents and monitor the operational status of the neutral line. In extreme cases, based on settings, the terminal allows short-term overcurrent and overheating operation of the neutral line and issues alarm signals to enable technicians to promptly diagnose and resolve faults. If the alarm persists and the neutral line overcurrent or overheating limits are reached, to protect the neutral line, the terminal will decisively output a trip signal, disconnecting the phase lines of the branch circuit switch to halt operation. This ensures both power supply continuity and maximum protection for the neutral line.

Application Sites:

High-speed rail stations, train stations, hotels, hospitals, exhibition halls, supermarkets, restaurants, electrical production lines, buildings, and other locations with significant 3N harmonics. It effectively manages excessive neutral line currents.
