Description

Technical Field

[0001] The present application relates to the field of GIS maintenance, and in particular to a preinstalled GIS maintenance platform. Background Art

[0002] With the development of the electric power industry, the increase in the transmission voltage level, and the formation of large-scale cross-regional networking, high requirements are placed on the reliability of the power transmission and transformation equipment of the power system. Compared with traditional open high-voltage equipment, gas insulated switchgear (GIS) has obvious advantages: compact structure, greatly reduced space occupied by the entire device; not affected by the external environment, high operating reliability; long maintenance cycle. Since its advent in the 1960s, GIS has developed rapidly and occupies an important position in the power transmission and transformation system. Many substations in my country will introduce GIS equipment during their development. Because GIS equipment has strong stability and small footprint, many substations in my country will give full play to the advantages of GIS equipment, thereby greatly improving the working efficiency of substations. However, in the current use of GIS equipment in substations, various faults are often encountered, such as operating mechanism failure, partial discharge phenomenon, excessive micro-water, and even SF6 gas leakage inside the GIS equipment. During operation, since the interior of the GIS equipment is a closed environment, the position of the conductor inside the equipment cannot be observed with the naked eye, which will cause discharge short circuits during operation, affecting the safe and stable operation of the power grid. During the installation and commissioning of GIS equipment, due to factors such as non-standard installation and commissioning process and poor construction environment, dust or microorganisms are left inside the GIS equipment, causing discharge after the GIS equipment is put into operation. Many devices are used directly outdoors, acid rain frequently falls in the area, and the humidity of the installation environment exceeds the standard, which accelerates the aging of the equipment and causes gas leakage inside the GIS equipment. These equipments are aged and circuit failures occur frequently, which has a great impact on the current application of GIS equipment in substations. The following problems exist in the current maintenance:

[0003] 1. No platform for GIS maintenance

[0004] During the maintenance of GIS, the lack of a dedicated maintenance platform has caused great trouble to maintenance personnel, making it difficult to carry out maintenance work efficiently and safely. Without a dedicated maintenance platform, a series of problems will arise:

[0005] 1) Increased safety hazards: Maintenance personnel need to operate directly on the ground or equipment, which greatly increases the safety risks of falling from heights, electric shock, etc.;

[0006] 2) Reduced maintenance efficiency: Due to the lack of a suitable maintenance platform, it is difficult for maintenance personnel to quickly and accurately locate the fault point, which prolongs the maintenance time and reduces work efficiency.

[0007] 3) Equipment damage risk: During the maintenance process, if the maintenance personnel operate improperly or lack the necessary support, it may cause damage to the GIS equipment and increase maintenance costs.

[0008] 2. Existing maintenance function technology is single

[0009] 1) Limited detection methods: Currently, many maintenance tasks still rely on simple methods such as traditional visual inspection and manual measurement, and lack advanced non-destructive detection technologies (such as ultrasonic testing, infrared thermal imaging, etc.), resulting in inaccurate fault detection and easy omission of potential problems.

[0010] 2) Insufficient diagnostic capabilities: Existing maintenance technologies can often only identify surface faults of equipment, but it is difficult to effectively diagnose deep-seated problems such as internal defects and material aging, which increases the risk of sudden equipment failure.

[0011] 3) Single maintenance method: When faced with equipment failure, the usually adopted method is to replace damaged parts or simply repair them. There is a lack of predictive maintenance strategies based on data analysis, resulting in high maintenance costs and low efficiency.

[0012] 3. No integrated platform for GIS maintenance:

[0013] As a core component of modern power systems, GIS has a complex structure and high integration, which places extremely high demands on maintenance work. However, many GIS sites currently lack an integrated and intelligent maintenance platform during maintenance, which results in cumbersome maintenance processes, low efficiency, and certain safety risks.

[0014] 1) Information island phenomenon: During GIS maintenance, information sharing between related systems is not smooth, forming information islands, making it difficult for maintenance personnel to obtain comprehensive equipment status information.

[0015] 2) Maintenance tools are not integrated: Existing maintenance tools are often scattered and independent, lacking unified management and scheduling, resulting in inconvenient use of tools and low efficiency during the maintenance process.

[0016] 3) Lack of intelligence in maintenance decisions: GIS maintenance decisions still rely mainly on manual experience and lack intelligent decision support based on data analysis, making it difficult to optimize maintenance work.

[0017] In summary, the problem of GIS maintenance without an integrated platform needs to be solved urgently. By building an integrated platform to achieve data integration, tool integration and intelligent decision support, we can greatly improve the efficiency and safety of GIS maintenance work and contribute to the sustainable development of the power system.

[0018] Therefore, it is necessary to develop a special platform for GIS maintenance. Summary of the invention
