Description

A remote management system for power distribution equipment

technical field

The utility model relates to a remote management system for power distribution equipment, which belongs to the technical field of power distribution applications.

Background technique

In recent years, the automation of distribution network has developed rapidly, which is reflected in the continuous improvement of the degree of power automation, which has laid a solid foundation for the rapid development of the national economy. The coverage area of the interconnected grid has gradually expanded, and the safe operation of power distribution equipment is important for the safety and reliability of the grid. The impact of operation is particularly prominent. The detection, fault diagnosis and status evaluation of power distribution equipment are of great significance to improve the reliability and utilization of power distribution equipment and realize the optimal management of equipment. At present, power distribution equipment below 10 kV needs Go to the installation place of the electric energy meter in the power distribution equipment room to check the power consumption. Only when the special power supply personnel read the meter can the user know the power consumption. When the transformer is overloaded or its cooling device fails, the temperature of the transformer winding will be too high. When the temperature reaches a certain value, the protection device will trigger the alarm device to alarm. If there is no staff in the duty room at that time, and the cooling measures are not taken in time, the transformer may be forced out of operation, and the sudden power failure of the electrical equipment is fatal for the IT industry. It will cause large economic losses, and the overload operation of the transformer will accelerate its aging. If a fire occurs, the power cannot be cut off in time, and the accident loss will also be enlarged.
