With the adjustment of the global energy structure and the continuous growth of power demand, smart grids are becoming the main development direction of modern power systems.As the basic support for the operation of the power grid, the continuous technological updates of power distribution equipment are gradually adapting to this change.From the perspective of practical application, the following combs the current development trend of power distribution equipment and several directions of technological upgrading.
1. Basic characteristics of intelligent power distribution equipment
Intelligent power distribution equipment refers to the addition of state perception, data transmission and control response functions on the basis of traditional power equipment, which can realize automatic operation and remote management to a certain extent.Its main features include：
- Real-time monitoring of equipment operating status, such as temperature, current, voltage, etc.;
- With a communication interface, it can exchange data with the background system;
- Support remote operation and rapid fault handling;
- Adopt energy-saving design and environmentally friendly materials to reduce the impact of operation on the environment.
2. The technical improvement direction of the main power distribution equipment
Traditional transformers mainly assume the voltage conversion function. On this basis, the current smart transformers have added monitoring and control modules, which can collect and analyze operating parameters in real time.For example, through the monitoring of oil temperature and winding temperature, potential problems can be discovered in advance and sudden failures can be reduced.This kind of equipment is more suitable for occasions where the reliability of power supply is required to be high.
Application and promotion of environmentally friendly gas switchgear
In the past, SF6 gas was commonly used as an insulating medium. Although its performance is stable, it has a greater impact on the environment.Now more and more switchgear are beginning to use dry air, nitrogen or other environmentally friendly gases as alternatives, which not only meet the insulation requirements, but also reduce the burden on the environment.The application of such equipment in urban distribution grids and new energy projects is gradually increasing.
A ring main unit is a node device used to distribute electricity in a distribution network.The current intelligent ring network unit can collect feeder data in real time, automatically complete fault judgment and power conversion operations, reduce manual intervention and improve processing efficiency.It is suitable for places where the continuity of power supply is required in parks, commercial areas, etc.
Standardized production of prefabricated substations
The prefabricated substation transfers the contents of the traditional on-site construction to the factory for completion, and the equipment is directly installed after being transported to the site as a whole.This method shortens the construction cycle and reduces the uncertainty of on-site construction.The internal monitoring system can be integrated and has unattended operating conditions, which is suitable for urban construction or temporary electric field scenes.
3.several directions of future development
More comprehensive data collection and higher degree of interconnection between devices;
Operation and maintenance gradually shift to predictive management to reduce sudden failures;
Product design pays more attention to standardization and interchangeability, which is convenient for later maintenance;
Environmental protection requirements have been increased to promote the application of green materials and low-energy design.
4.Conclusion
The technological upgrading of power distribution equipment is a microcosm of the intelligent and refined development of the power system.Kechang Electric continues to pay attention to industry changes, continuously optimizes product performance based on actual needs, and provides users with stable and reliable power distribution solutions.In the future, we will continue to further explore product functions and application experience.
