Description

Technical Field

[0001] The present invention relates to the field of switch cabinet equipment, and in particular to a fully digital real-time monitoring and control method for a switch cabinet. Background Art

[0002] In the construction and operation of power systems, switchgear, as the core control and protection equipment, plays an important role in power distribution, line protection and system safety. Traditional switchgear mainly relies on mechanical relays and manual operation to realize its functions. These devices have achieved certain achievements in stability and reliability. However, with the rapid development of smart grids and industrial automation, higher requirements are placed on the performance of switchgear, especially in terms of digitalization, intelligence and remote monitoring.

[0003] Existing switchgear generally has the following limitations:

[0004] 1. Limited data collection capabilities: Traditional switchgear usually only has basic measurement functions such as current, voltage, temperature, and environmental factors, and lacks comprehensive monitoring and data collection of equipment status.

[0005] 2. Insufficient data processing capabilities: Even if some data is collected, existing switchgear has limitations in data processing capabilities. They usually lack advanced data analysis and machine learning algorithms and cannot deeply explore the value and patterns behind the data.

[0006] 3. Data silos between systems: There is often a lack of effective data integration and communication mechanisms between different sensors and monitoring systems, which makes it easy for data silos to occur and prevent a comprehensive understanding of the overall operation of the switchgear.

[0007] 4. Long fault response time: Due to the lack of real-time monitoring and analysis capabilities, traditional switch cabinets often require manual inspections to discover problems when faults occur, resulting in long fault response times.

[0008] 5. High maintenance cost: Due to the lack of predictive maintenance function, the maintenance of traditional switchgear is usually time-based or event-driven, which makes it difficult to achieve on-demand maintenance, increasing maintenance costs and power outage duration.

[0009] 6. Low operating efficiency: The operation of traditional switchgear relies on on-site manual operation and cannot be remotely controlled, which reduces the efficiency and flexibility of operation.

[0010] 7. Lack of adaptability and flexibility: The average service life of switchgear is generally 15-20 years. The design of traditional switchgear is usually relatively fixed, which makes it difficult to adapt to the rapid iteration and upgrading needs of new technologies, limiting its long-term development and application.

[0011] Through the above analysis, it can be seen that digital intelligent switchgear has obvious advantages and necessity in terms of technical background, market demand and development trend, and is expected to become an important supporting equipment for future power system construction and operation. Summary of the invention

[0012] The technical problem to be solved by the present invention is to provide a fully digital real-time monitoring and control method for a switch cabinet, which can realize the comprehensive collection, in-depth analysis and effective utilization of the system data of the entire switch cabinet, fully tap the data value in the system, and improve the digitalization level, intelligence level, operation efficiency and safety of the switch cabinet.
