Abstract
Description
Technical Field
[0001] This application relates to the field of mobile GIS combined electrical appliances, specifically to a GIS maintenance platform trolley. Background Technology
[0002] With the development of the power industry, the increase in transmission voltage levels, and the formation of large-scale inter-regional grid interconnections, high demands have been placed on the reliability of power transmission and transformation equipment. Compared with traditional open-type high-voltage equipment, gas-insulated switchgear (GIS) has significant advantages: compact structure, greatly reducing the footprint of the entire unit; unaffected by external environment, resulting in high operational reliability; and long maintenance cycles. Since its introduction in the 1960s, GIS has developed rapidly and occupies an important position in power transmission and transformation systems. Many substations in my country have introduced GIS equipment during their development because of its strong stability and small footprint, allowing many substations to fully utilize its advantages and significantly improve substation efficiency. However, various faults are frequently encountered during the use of GIS equipment in substations, such as operating mechanism failures, partial discharge, excessive moisture, and SF6 gas leakage inside the GIS equipment. During operation, because the interior of the GIS equipment is a closed environment, the position of the internal conductors cannot be observed visually, which can lead to short circuits and affect the safe and stable operation of the power grid. During the installation and commissioning of GIS equipment, factors such as improper installation and commissioning procedures and poor construction environments can leave dust or small debris inside the GIS equipment, causing discharge phenomena after the equipment is put into operation. Some GIS equipment is installed outdoors, and due to frequent acid rain in the areas where it is located, and the high humidity and moisture content in the installation environment, the equipment ages rapidly, leading to SF6 gas leakage. These issues, including equipment aging, circuit faults, and short circuits, significantly impact the application of GIS equipment in substations. Therefore, necessary maintenance work is required for GIS equipment. However, due to the lack of a systematic approach to maintenance, various problems exist, such as:
[0003] 1. There is currently no dedicated maintenance platform for GIS.
[0004] The lack of a dedicated maintenance platform during GIS maintenance causes significant inconvenience for maintenance personnel, hindering efficient and safe maintenance work. A series of problems exist:
[0005] 1) Increased safety hazards: Maintenance personnel need to operate directly on the ground or equipment, which greatly increases the safety risks of falls from heights, electric shocks, etc.
[0006] 2) Reduced maintenance efficiency: The lack of a suitable maintenance platform makes it difficult for maintenance personnel to quickly and accurately locate the fault point, thereby prolonging the maintenance time and reducing work efficiency.
[0007] 3) Equipment damage risk: During the maintenance process, improper operation by maintenance personnel or lack of necessary maintenance equipment may damage the GIS equipment and increase maintenance costs.
[0008] 2. Existing maintenance functions and technologies are limited.
[0009] 1) Limited detection methods: Currently, many on-site fault repair work still relies on traditional simple methods such as visual inspection and manual measurement, lacking advanced non-destructive testing equipment (such as ultrasonic testing, infrared thermal imaging, etc.), resulting in inaccurate fault detection and easy to miss potential problems.
[0010] 2) Insufficient diagnostic capabilities: Existing on-site maintenance equipment can often only identify surface faults in equipment, but it is difficult to effectively diagnose deeper problems such as internal defects and material aging, which increases the risk of sudden equipment failure.
[0011] 3) Limited maintenance methods: When faced with equipment failure, the usual approach is to replace the damaged parts, lacking predictive maintenance strategies based on data analysis, resulting in high maintenance costs and low efficiency.
[0012] 3. GIS maintenance lacks an integrated platform:
[0013] As a core component of modern power systems, GIS (Geographic Information System) has a complex structure and high degree of integration, placing extremely high demands on maintenance work. However, many GIS sites currently lack an integrated, intelligent, and mobile maintenance platform, resulting in cumbersome and inefficient maintenance processes, as well as certain safety risks.
[0014] 1) Information silo phenomenon: During GIS maintenance, information sharing between various related systems is not smooth, forming information silos, making it difficult for maintenance personnel to obtain comprehensive equipment status information.
[0015] 2) Low integration of maintenance tools: Existing maintenance tools are often scattered and independent, lacking unified management and scheduling, which leads to inconvenience in using maintenance tools and low maintenance efficiency during the maintenance process.
[0016] 3) Lack of intelligent maintenance decision-making: GIS maintenance decisions still mainly rely on human experience and lack intelligent decision support based on data analysis, making it difficult to optimize maintenance work.
[0017] In summary, the problem of lacking a mobile integrated platform for GIS maintenance urgently needs to be solved. Summary of the Invention
[0018] The purpose of this application is to provide a dedicated GIS maintenance platform vehicle that meets the needs of GIS maintenance, fills a gap in the industry, enables GIS maintenance to use more specialized tools, eliminates the need for non-professional platforms, reduces costs, alleviates the labor intensity of personnel, and provides higher safety.

[0023] The vehicle body shell is made of non-metallic composite fiber material; the main frame is made of steel channel steel and rectangular steel pipe welded together; the walls are made of corrugated plate welded together, with a hot-sprayed zinc coating and a high anti-corrosion paint; the inner layer is made of water-resistant, anti-corrosion, flame-retardant and heat-insulating polyurethane board; the top is made of stainless steel double-sloped roof structure, and then insulated with rock wool or polynitride, with aluminum composite panel ceiling; the bottom is made of wood-based ceramic anti-static floor.
[0024] The GIS push-pull transport component consists of longitudinal rods, transverse connecting rods, and support legs. The longitudinal rods and transverse connecting rods form a support structure that supports the GIS tank component. The support legs are located at the end away from the GIS maintenance vehicle body to support the support structure on the ground. The support legs are connected to the longitudinal rods through fixed pins and connecting plates.
[0025] The lifting and traction assembly includes connecting rods, a balancing lifting assembly, and moving wheels. The connecting rods connect to the GIS maintenance vehicle body, the balancing lifting assembly automatically compensates to maintain the balance of the GIS maintenance vehicle body, and the moving wheels facilitate the movement of the GIS maintenance vehicle body.
